This was, of course,before he received his M. D. from the University ofChicago in 1937. There will be those who will remark thatgrave digging laid the ground-work for his successfulcareer as a medical plumber, a urologist. But I wouldn'tsay that. I shall pun, however, to say that he continued acareer digging-digging for the facts both as a researcherand a unique medical administrator.He completed his graduate training, internship, andresidency here in Dallas B. Phemister's great Depart­ment of Surgery. In the 1930s and early 1940s it was arare University of Chicago surgical department residentwho failed to become a professor of surgery someplacerather soon. Phemister, Dragstedt, Huggins and their as­sociates were great teachers, in part because they knewhow to select exceptional students. Vermeulen was cho­sen. His choice of urology as a subspecialty brought himunder the guidance of Charles Huggins, who was almost8 singlehandedly guiding the surgical specialty of urologyinto the scientific era of the twentieth century.As a urology resident Vermeulen had a patient whoappeared with the intractable pain and almost total dis­ability of prostatic cancer with metastases to the bones ofthe spine and pelvis. Dr. Huggins' studies with dogs hadsuggested that some prostatic tumors were dependent onthe testicular male hormone. Accordingly, castration wassuggested to the patient, who became the first to be sotreated for advanced prostatic cancer. After the opera­tion, improvement was spectacular and the patientwalked out of the hospital. He died twelve years later ofheart disease.Vermeulen's powerful, almost evangelistic descriptionof the drama of this great medical discovery, while hewaved X-ray films in his long arms, held a normally pas­sive medical conference audience spellbound. To listenwas an inspirational event. This presentation served as aremarkable revelation of the true emotional constitutionof this usually dispassionate-appearing medical scientistand teacher, for Dr. Vermeulen feels and lovesdeeply-his family, his patients, his students, his col­leagues and his University.At the completion of his training Vermeulen joined thefaculty of the University of Illinois as associate professorof surgery. In 1953 he returned here as professor ofsurgery and head of the urology section. He was de­termined to continue the tradition of research and train­ing, so determined that he was even willing to borrow anidea from the Department of Medicine-a system of rota­tion on and off major teaching and clinical responsibilitiesso that the urologists would have sufficient continuoustime to do productive research.His own research interest was directed toward gainingan understanding of the factors which cause urinary cal­cium stone formation and those which inhibit their forma­tion. He was among the first to emphasize the importanceof the super-saturated state of urine with respect to theionic constituents of the stones. He was the first to pointout that these stones formed at the renal papillary tips.He also contributed substantially to the now-confirmedconcept that normal urine contains a small molecularchemical which maintains the solubility of the con­stituents of stones.As head of the urology section he supervised the train­ing of Ed Lyons, Bill Gill, Warren Chapman, GeorgeMiller, John Sawyer, Duncan Govan, Tom Borden,Floyd Fried, James Roberts, John Sommer, BirdwellFinlaysen, David Proctor, and Marvin Morrison. Ofthese thirteen, ten have full-time academic posts at theUniversity of Chicago or elsewhere-in keeping with theUniversity's aim to be a teacher of teachers.When Dean Coggeshall retired, Vermeulen found him­self on the faculty committee elected to advise PresidentKimpton on the appointment of a new dean. The eight­person committee elected him chairman. It was a com­mittee with a difficult challenge, for at this time the basicscience faculty was seriously considering breaking theDivision of Biological Sciences into two portions, andthis committee became the focal point for such a serious,controversial proposal. Vermeulen's handling of this dif­ficult political situation-which amounted to holding theDivision together during the dean selection process-was so impressive that President Kimpton gave serious con­sideration to appointing him dean.Five years later when Dr. Jacobson became dean, hepersuaded Vermeulen to become the associate dean forclinical affairs. I n the eight years he served in the Dean'soffice, the principal crisis he faced was not political butfinancial, and similar to that of other medical institutionswhich seemed to be able to use money faster than it camein. He was a determined digger for facts in a hospitaladministration whose main aim had not been fiscalsolvency but the provision of teaching and researchfacilities for a growing and demanding faculty. Hisanalysis of the facts and subsequent proposals probablysaved our school as a leading private medical institution.President John Wilson has asked me to read the follow­ing statement concerning Vermeulen's accomplishmentsin the Dean's office. "In addition to those virtues whichhave been recognized in Dr. Vermeulen's exceptionalservices as a faculty member in the Division of BiologicalSciences and the Pritzker School of Medicine, it is mypleasure to call attention to others of a broader scope.From the point of view of the University as a whole, theproblem of establishing financial integrity and stability inthe Biological Sciences Division and the Pritzker Schoolof Medicine was one of the several crises during the earlyyears of the 1970s."As is the case with most problems in the biomedicalarea, it was not a minor one, and in the resolution of thisvaried and complex difficulty no one was of more help toan embattled dean and provost than Dr. Vermeulen. Hisintimate knowledge of the internal operation of both theDivision and the school, his absolute personal integrity,and his judicious sense of balance between the parochialinterests that reside on the west side of Ellis A venue, incontrast to the needs of the University generally, com­bined to make his advice an invaluable resource."It is also quite fitting that his distinguished services tothe University should be recognized at the same time thathe is receiving the Gold Key of the Medical Alumni As­sociation. At Mr. Wilson's request I am privileged toannounce for the first time that effective July I st of thisyear, Dr. Vermeulen became the Lowell T. CoggeshallProfessor of Medical Sciences at the University.-Dr. Richard L. Landau9Distinguished Service Award PresentationsDr. Robert McCormackIn awarding the Distinguished Service Award to Dr.Robert M. McCormack, the University of Chicago rec­ognizes one of the great pioneers and leaders in the im­portant field of plastic and reconstructive surgery. Dr.McCormack's contributions place him at the forefront ofhis specialty in all three categories of the academic triad.His numerous research publications have led to ad­vances of knowledge, particularly in matters related todiseases of the hand and to burns. He has been widelyrecognized as a superb clinical surgeon, and this recogni­tion was formalized by his designation as the clinician ofthe year in 1975 by the American Association of PlasticSurgery. As a teacher, he has served the University ofRochester faithfully and well for many years, and hasrecently received national recognition by being namedthe 1976 Visiting Professor for the Educational Founda­tion of the American Society of Plastic and Reconstruc­tive Surgery.Dr. McCormack received his undergraduate degreefrom Swarthmore College, where he excelled in footballas well as in academic pursuits. He received his M.D.degree from the University of Chicago School ofMedicine in 1943. Following an internship and one yearof residency at the University of Rochester, he enteredthe army and began to develop his life-long interest inhand surgery. He was chief of the Hand Surgery Serviceat the William Beaumont Army Hospital from 1945 -1947. After completing his residency at the University ofRochester in 1949, he joined the faculty of that medicalschool. He rose rapidly to the rank of professor in 1957and was named vice-chairman of the Department ofSurgery in 1968.In addition to his clinical and research contributionsand important teaching activities at the University ofRochester, Dr. McCormack has been a recognizedleader in surgery both nationally and internationally.Among his 32 society memberships are included fellow­ship in the American Surgical Association, and electionto Alpha Omega Alpha. He has served as an officer of allof the important societies of his specialty, including thepresidency of the American Society of Surgery of theHand in 1964, chairman of the Plastic Surgery ResearchCouncil in 1966, chairman of the American Board ofPlastic Surgery in 1968, president of the American Asso­ciation of Plastic Surgeons in 1968, chairman of theAmerican College of Surgeons Council for Plastic andMaxillofacial Surgery in 1963, and president of the Amer­ican Burn Association in 1971.He has undertaken broader responsibilities in medicaleducation and served as the vice-president of the Councilof Medical Specialty Societies in 1972 after many years ofleadership in this organization. He has served on theResidency Review Committee for Plastic Surgery and isthe associate editor of four major journals.Dr. McCormack has received many honors and10 awards, including the Award of Merit from the RochesterAcademy of Medicine, and has given a number of impor­tant lectureships. It is with pride that the University ofChicago recognizes Dr. Robert McCormack as a trueleader in American surgery by the presentation of thisDistinguished Service Award.-Dr. David SkinnerDr. Daniel PorteIt is a great pleasure for me to introduce Dr. DanielPorte, J r., one of the recipients of a Distinguished Ser­vice Award. Dan was born in New York City in 1931. Hereceived his B.A. in 1953 from Brown University.Thereafter, he came to the University of Chicago for hismedical training and was awarded his M.D. degree withhonors in 1957. Following a year of internship in SanFrancisco he was appointed a United States PublicHealth Service fellow at the Cardiovascular ResearchInstitute of the University of California. He completedhis service in the U.S. Navy and his residency by 1963.In 1963 Dr. Robert Williams, who has been so success­ful over the years in attracting the best young people inthe country to join his diabetes-endocrinology trainingprogram, recruited Dan to Washington University inSeattle. There Dan blossomed and rapidly progressed upthe academic ladder from an advanced research fellow ofthe American Heart Association to assistant professor,associate professor and finally full professor of medicinein 1973. In addition, he was appointed associate chief ofstaff for research at the Seattle Veterans AdministrationHospital, and chief, Division of Endocrinology andMetabolism at the same institution in 1975. This yearDan assumed the directorship of the Diabetes­Endocrinology Research Center at the University ofWashington.Dan has received a number of important awards andhonors, including the University of Chicago MedicalHonor Scholarship, a NIH Career Development Award,and the Eli Lilly Award of the American Diabetes Asso­ciation in 1970. In addition, he is a member of manynational research and professional societies, includingthe American Society of Clinical Investigation, the As­sociation of American Physicians, the American Physio­logical Society, the Endocrine Society and the AmericanDiabetes Association.This year, Dan was elected chairman of the MedicalAdvisory Board of the Juvenile Diabetes Foundation, anappointment which indicates the high esteem in which heis regarded by both the scientific community and the laymembers of the organization, who are mainly parents ofdiabetic children.Since 1961, Dan has published over 100 scientific man­uscripts. In the short time available this afternoon, I canonly touch on the highlights of his very substantial scien­tific contributions. The first field that I would like to men­tion is that of insulin secretion.In 1966 Dan and his coworkers initiated a series ofclassical experiments which described the inhibitory ef­fect of epinephrine and norepinephrine on insulin releasein man. In subsequent years Dan has been at the fore­front of research aimed at elucidating the role of the cen­tral and peripheral nervous systems in controlling hor­mone secretion from the islets of Langerhans.In addition, he has integrated this work with incisiveand elegant experiments aimed at defining the secretorydefect in pancreatic beta cells which underlies the dia­betic syndrome. A hallmark of his research has been thecare with which he has designed and carried out studiesin healthy controls and patients, and the meticulous man­ner in which he has analyzed his findings and drawn ap­propriate conclusions.This then is the factual background. In itself, it wouldbe sufficient to commend Dan for this award. However,those of you who have had the pleasure of knowing Danas a friend and colleague know, as I do, that it only de­scribes one aspect of his accomplishments. The otherconcerns his warm personality, readiness to be helpful,generosity with ideas, and leadership qualities. For sometime I have mentioned how impressed I have been by thespirit of unity among scientists working on diabetes­related research. Dan is one of those who nurtures thisatmosphere and provides the basis for its existence.For all these reasons, it gives me special pleasure topresent a Distinguished Service Award of the MedicalAlumni Association to Dr. Daniel Porte, J r., and to wishhim continued success and happiness in the years ahead.-Dr. Arthur RubensteinDr. Olaf SkinsnesThe man that I am honored to present is a humanitarianfirst and foremost. Olaf Kristian Skinsnes was born inChina, son of a missionary physician, attended St. Olaf'sCollege, and joined the University of Chicago as a stu­dent in 1940. He obtained a Master's Degree in 1946 andM.D. and Ph.D. degrees in 1947 from this institution.He remained at the University as an assistant inpathology until 1946, when he took an internship at NewYork Hospital. From there he went to the University ofHong Kong, where he remained as a senior lecturer until1959, then returned to his alma mater as professor ofpathology.To the younger members of the Pathology Departmentat the University of Chicago and to many of our medicalstudents, these were the years when we learned to ap­preciate Dr. Skinsnes as a teacher, investigator andfriend. His life-long interest in Oriental culture and hisscientific interests in the medical and social aspects ofinfectious diseases added a new dimension to the teach­ing of this medical school, one achieved by few, in any,other academic institutions. It was here that he began towrite the multi-volume Chinese Medical History.It may be said that the Chinese proverb, "He who isfor one day my teacher is my father for life," best appliesto Dr. Skinsnes. But his achievements as a teacher andtrainer are only a small measure of the man we are honor­ing. For many years, he has been a leader in the field ofleprosy research, as we witnessed this morning in hislecture. Research on leprosy, however, does not confineitself to a search for the causative agent-which his coun­tryman, Armauer Hansen, had allegedly described first in1874-nor to the development of vaccine. To Dr. Skins­nes, research in leprosy is social medicine in the bestsense of this misused term, whether it is manifested in theestablishment of.a leprosorium near Hong Kong or by themany humanitarian services he has rendered to patientswith leprosy throughout the world.In presenting to Dr. Skinsnes the Distinguished Ser­vice Award, we honor the scholarship and humanitarianspirit that he has represented to us for so long.-Dr. Werner KirstenDr. Joseph SkomIt is a real pleasure today to share with all of you thistraditional and still exciting event in which the Universityof Chicago Medical Alumni Association honors some ofits members, and a pleasurable task to introduce one ofour alumni, Joseph Skom, who migrated to the Univer­sity of Chicago from the little village of Aurora after threeyears of military service, graduating with honors.He then went on to get his S.B., an M.S. in Physiologywith honors, and an M.D. with honors, all at the Univer­sity of Chicago. Joe then interned at Johns Hopkins andreturned to the University of Chicago where he com­pleted his residency and a subsequent fellowship in pub­lic health.He remained on the faculty for the next few years andthen went into practice with a distinguished group ofinternists on the north side, where he has remained to thepresent time. As a member of the faculty of Northwest­ern University he has continued research begun at theUniversity of Chicago. Among his many honors, JoeSkom is currently president of the Illinois State MedicalSociety.Although he is certainly well known for his scientificworks spanning the fields of experimental hypertension,renin and antirenin, immunology, endocrine disorders,and his very important work in drug abuse, Joe is perhapsbest known for a non-scientific event in his life.One morning, one of the adventurous Skom childrendecided to broaden her horizons, and an object near athand provided the opportunity to do just that. The littleSkom climbed higher, higher, and ever higher, and finallyarrived somewhere near the top of a rather tall radiotower in their neighborhood. This event received widecoverage, even on national television, which continuedfor several weeks thereafter. The notoriety of that eventhas subsequently subsided and one rarely hears of itthese days.Perhaps one of the most pleasant events related to theUniversity of Chicago in the life ofJ oe and Edie Skom isthe fact that this daughter is now a sophomore at thePritzker School of Medicine. Of particular poignancy isthe fact that Harriett's apartment when she first came tothe University as a freshman medical student was the11exact place in which Joe and Edie Skom had started theirmarried life at the University of Chicago.Joe, it is a distinct pleasure to present to you this Dis­tinguished Service A ward.-Dr. Henry RusseDr. Donald F. TapleyDonald F. Tapley was born in Woodstock, Nova Scotia,went to undergraduate school at Acadia University, andgraduated from the University of Chicago School ofMedicine in 1952. He then ventured east to begin his longaffiliation with the Columbia University College ofPhysicians and Surgeons (P & S), starting as an intern atPresbyterian Hospital in July, 1952. Regrettably, I didnot know Dr. Tapley during his years at the University ofChicago, but I did share the next two years on the P & Shousestaff.He spent these two years under the tutelage of Dr.Robert F. Loeb, whose austere high standards as chair­man of medicine surely left an imprint on Tapley andhelped shape his career, as they did for so many otheryoung physicians.Next, Tapley dove into rather basic medical-in factendocrinologic-research, spending a year withLehninger at Johns Hopkins and a second year at Ox­ford. During this time he studied fundamental aspects ofthyroid hormone action, and found that thyroxine in­duced swelling of mitochondria and the release ofpyridine nucelotides from mitochondria. This responsepreceded and perhaps caused the subsequent uncouplingof oxidative phosphorylation.He returned to Columbia in 1956 as an assistant pro­fessor and continued as an endocrinologist-teacher­researcher.The focal point of his research was a search for thefundamental effects of thyroxine on mitochondrial func- tion. In a series of studies extending over eight years,performed in collaboration with M. P. Primack and J. L.Buchanan, Dr. Tapley found that triiodothyronine, givenin vivo, increased mitochondrial protein synthesis inthree hours. Thyroxine added to mitochondria in vitroalso promptly induced new protein synthesis. This re­sponse was supported by an A TP generating system, anddid not require prior conversion of thyroxine totriiodothyronine. The protein synthetic response couldbe dissociated from the action of thyroxine on oxygenconsumption by puromycin.During this time, Tapley gradually developed a reputa­tion among students and house officers as an exceptionaladviser, confidant, and teacher. Perhaps his own interestshifted gradually toward medical education.In 1970, with his appointment as Associate Dean forFaculty Affairs, this role became official, and in 1973 hebecame the Dean.Donald is credited with leading a renaissance at Co­lumbia. These very words were used at P & S a fewweeks ago, so it can be said with certainty that this is howhis own faculty views his accomplishments in recentyears. Perhaps renaissance may not be the perfect word,since P & S has never been anywhere but at the top inmedical education. However, under his leadership therehas been a rebirth of confidence in the school, sweepingchanges in the curriculum, the recent development of amagnificent new library and instructional facility, and de­velopment of a sense of progress which has altogethergiven P & S a new air.His accomplishments are large at barely the midpointof his career. The University of Chicago believes that itteaches teachers. Donald is certainly a prime example ofthe best the University can do.-Dr. Leslie De GrootFlexner RevisitedDonald F . TapleyAbraham Flexner is widely regarded as one of the greatheroes of American medicine. Near the turn of the cen­tury, he found an abundance of poor schools with grosslyinadequate standards-schools whose only criteria forentry were the abilities to read, write and pay the bills.He found also that unfortunates who needed the help ofdoctors were more likely to be cared for by "charlatans"than by physicians adequately grounded in scientificmedicine. He enumerated the virtues and analyzed thedeficiencies of the then-existing institutions of medicaleducation in the United States, rated each school, andproposed the measures which would raise Americanmedical education to the level of that of Germany, En­gland and France.These steps included the elimination of inferior schoolsand the universal adoption of the requirement that medi­cal schools offer a graded basic science curriculum, fol­lowed by clinical clerkships conducted in the wards of a12 hospital. In addition, he stressed the importance of full­time faculty, arguing that principles of medicine shouldbe taught by professors, and he insisted that research lab­oratories be linked with clinical facilities. Three strongconvictions lay behind Flexners advocacy of these mea­sures: a belief in the importance of the university; thepostulate that medical education could thrive only in anenvironment in which biomedical research was per­formed at the highest level; and a deep sense that in­stitutions of medical education should be protected frominvolvement in health care delivery.It is of interest that Flexner found the University ofChicago "neither fish nor flesh nor good red herring"because its medical school was divided. Genuine pre­clinical university instruction was offered on the campusitself; clinical instruction conducted by local pro­fessionals took place in a remote part of the city. As youknow, Flexner was largely responsible for changing theUniversity of Chicago medical school into "good redherring" by insisting that clinical instruction be broughtto the University campus.The changes in American medicine with which Flexneris almost universally credited began considerably earlierthan his time. The rise of German scientific medicine inthe last half of the 19th century, the development ofgraduate university education in the United States, theformation of the Johns Hopkins University medicalschool, the efforts of the Association of American Medi­cal Colleges and even those of the American MedicalAssociation were the main sources of the recom­mendations which Flexner incorporated in his report.Thus, it may be more correct to see Flexner not somuch as the initiator of broad and sweeping reform, butrather as the catalyst who with the greatest energy andcourage applied standards advanced by others, and rec­ommended measures conceived by others in order to im­-prove American medical education. Sociologist RobertMerton has noted that Flexner's report, which carriedthe imprimatur of the Carnegie Foundation for the Ad­vancement of Teaching, "largely closed the gap betweenprivate knowledge of departures from accepted standardsand public acceptance of those standards." His ideasmay have been less original than is commonly assumed,but the changes recommended by Flexner have come todominate American medical education.The changes to which Flexner's reforms led have had at least six consequences:• The quality of American medical education has im­proved greatly in comparison with that which was pro­vided in the era of the diploma mills.• Medical knowledge and capabilities have expandedenormously. Because of this growth, the period sinceWorld War II can be compared in scientific productivitywith the "Golden Era" of German medicine during thelatter half of the 19th century.• A many-stranded bond of interdependence has de­veloped between teaching and research in medical educa­tion. The sum of biomedical knowledge has long ex­ceeded anyone individual's capability for mastery.Hence, the medical school's function has become that ofinstilling in its graduates a knowledge of the broad out­lines of the many relevant disciplines, a critical compe­tence, and a disposition to lifelong self-education.• The quality of medical care within those hospitalsclosely affiliated with our medical school has improveddramatically. The improvement is a direct consequenceof more extensive biomedical research and more rigorouseducational procedures.• There has been an important change in the expecta­tions of the American public which is related to the em­phasis Flexner placed on research. Since World War II,we have indeed achieved a large number of authenticadvances in health care, and an eager public, to whomthese marvels of modem medicine have been incessantlylauded, has been waiting for the universal application ofmethods to make everyone healthy, happy and creative.These visions, at least in their exaggerated form, arenot the creation of responsible physician-scientists. Butas the public has come to perceive a failure to deliverboth the authentic and the more fanciful promises ofmodem medicine, and as the deficiencies of health caredelivery remain largely uncorrected, disillusionment hasset in. And it is on the medical schools that the public,through its elected representatives and through the press,places a large part of the responsibility for these disap­pointments.• Finally, in following what they construed as the im­plications of the Flexnerian model, most medical schoolshave remained comparatively isolated from social con­cerns, and lack the means to effectively enter into publicdebate. In particular, medical schools have failed to takethe lead in studying the problem of health care deliveryand developing recommendations as to how an improvedsystem should be organized.Society is now telling us that we have responsibilitiesas physicians as well as professors. The voices are be­coming more strident. But it is unfair that society shouldblame the medical schools for the maldistribution ofphysicians; it is unfair that society should blame the med­ical schools for training too many specialists; it is unfairthat society should blame the medical schools for thedeteriorating care of the population which surrounds us,particularly in the urban ghettos.Or is it?We do have more influence on the career choices of ourstudents than we care to admit. We do have more in­fluence (if not control) over the graduate training pro-13grams in our hospitals than we willingly acknowledge.And we do bear a major responsibility, because of ourlong-standing holier-than-thou attitudes towards the"LMD's" (local medical doctors) in our communities,for the disappearance of the practicing physicians in ourimmediate surroundings.I n one way it is fortunate that the health care deliverysystem has become so chaotic. The mess is so great andthe problem so complex that it now can be solved only bya massive research and development effort. And researchis what both we and the University consider ourbailiwick. Without taking on additional corporate re­sponsibility for patient care, we must assume leadershipin the development of new models of health care, modelswhich result in the effective delivery of care to hundredsof thousands of men and women in the underservedurban and rural areas. This would correct the problems ofgeographic and specialty distribution without, societysays, increasing the cost. I am sure that Flexner, were hehere, would consider this a problem worthy of the talentswhich University medical schools can bring to bear uponit.At the Columbia University College of Physicians andSurgeons, we have begun to approach the problem withthe establishment of a "Center for Community HealthSystems." This research center enlists the substantialand varied resources of the university jointly with thefaculty of medicine and its affiliated teaching hospitals ina systematic attack on problems in organizing and de­livering health care, especially in urban areas.The problem we face is immense-our affiliated hospi­tals in New York City alone serve a population greaterthan that of the city of Boston. And outside our hospitalswe serve this population badly. We do not intend that theCenter itself will assume the responsibility for providingmedical care. Rather, it is intended to serve as a researchand development arm and to design and evaluate newpatterns of health care delivery. We have begun to makeinroads on the problem, but the task is formidable.It clearly is urgent that we rethink the traditional divi­sion oflabor within the health professions. We have beentoo slow in sharing our professional responsibilities withour colleagues. Society is now telling us that it cannotand will not support the use of highly trained physiciansto do tasks which can be performed by other pro­fessionals whose training is less costly. But we can suc­cessfully transfer the responsibility for performing suchtasks only if we succeed in changing our educationalmethods so that the physician, the nurse and the alliedhealth professional are trained in a new and appropriatelycoordinated setting. This, too, is a research and educa­tional challenge worthy of university medical schools.The Flexnerian legacy, in which most medical schoolsremain comparatively isolated from social concerns, hasleft us with few effective ways of entering into publicdebate, or of influencing public policy, or even of project­ing our true aspirations and image.Describing this year's Columbia graduation, the NewYork Times reported:"One of the honorary-degree recipients kissed theUniversity president gratefully, a bearded philosophernoted for a historical study of skepticism chewed gum14 throughout the long citation of his achievements, andstudents mockingly chanted, 'socialized medicine,socialized medicine' as the dean of medicine crossed theplatform. The dean grinned at the students."Is it mockery when undergraduate students confront uswith a call for "socialized medicine"? The New YorkTimes thinks so. There is indeed something wrong withour image when society, as reflected in a newspaper ofthis caliber, does not realize that academic faculties suchas those at Columbia University and the University ofChicago have been practicing a form of "socializedmedicine" for half a century, and that these sameacademic faculties, far from opposing the development ofa National Health Plan, are actively involved in the evo­lution of that scheme, concerned that it be as effectiveand as rational as possible.A major legacy of the Flexner era has been a remark­able cadre of physician-scientists. Nothing must be doneto weaken a process which has had such results. Butsociety now is telling us that this is not enough. It istelling us that we must reform our educational processesin order to develop over the next quarter century anequally remarkable cadre of physician-citizens. If suchphysician-citizens are to emerge from our schools, medi­cal students must be involved with disciplines relevant tothe improvement of our health care system--disciplinessuch as the social and behavioral sciences, economictheory, political theory, planning and administration.At the undergraduate level, I fear that (as with mostareas of medicine) we can but expose them to the rudi­ments and provide them with outstanding role models;postgraduate training programs must provide the refine­ment. We have been eminently successful in developingthe physician-scientist; I see no reason why we cannot beequally successful in developing a similarly remarkablecadre of physician-citizens. It may take another quartercentury to undo the damage of the past, but the damagemust be undone. And the spearhead for any change in themedical system must be the physician.We must rethink the Flexnerian model of medical edu­cation. Both biomedical research and greater social re­sponsibility must be provided for. Universities arenotoriously ineffectual whenever they attempt to dealwith the societal problems which surround them. Thechallenge is how to remain deeply rooted in the Univer­sity tradition while responding effectively to the needs ofsociety.If Flexner were here today, he would be gratified bymost of the changes that followed upon the recom­mendations published in his report. However, I think hewould be surprised at some of the unfortunate conse­quences of his legacy-and I venture that he would judgethe assumption of leadership by a medical school (even aUniversity medical school) in solving these problems tobe a worthy effort.Or.

Hoffmann, Ph.D.Rat pineal serotonin: acetyl coenzyme A: N-acetyl­transferase activity is normally elevated during periods ofdarkness and depressed during periods of light. The re­duction of induced levels of N -acetyltransferase activityby light has been demonstrated to have a half-time ofabout three minutes. In contrast, when protein synthesisis blocked pharmacologically, the half-time of the en­zyme fall is about sixty minutes. This suggests that expo­sure of animals to light results in an active inhibition ofenzyme activity. Information regarding environmentallighting reaches the pineal via a complex neuronal path­way.Experiments were designed to pharmacologicallyblock neurotransmission along this pathway and so blocklight suppression of N -acetyltransferase activity. Alphablocking agents such as phenoxybenzamine and phen­tolamine successfully blocked the decrease in pinealN -acetyltransferase activity following exposure of ani­mals to light for ten minutes. When animals were ad­ministered the alpha agonists methoxamine and clonidineintraperitoneally, falls in enzyme activity occurredmimicking those produced by light. In contrast, intra­peritoneal injections of norepinephrine and phenyle­phrine did not affect levels of enzyme activity. However,norepinephrine did cause a fall in activity when it wasinjected intraventricularly. These results suggest that analpha adrenergic receptor mediates light suppression ofenzyme activity. Also, since norepinephrine only pro­duces a fall when the blood-brain barrier is bypassed withintraventricular injections, it is further suggested that thisreceptor is located within the central nervous system.These data demonstrate that stimulation of a receptor sitewithin the central nervous system can modulate a dis­crete biochemical event in a peripherally innervated endorgan.Enzyme Efflux from Skeletal Muscle: Reductionby DiethylstilbestrolRobert DempseySponsor: Dr. Louis CohenDiscussant: Dr. Alfred HellerIt has previously been shown that oral diethylstilbestrol(DES) lowers the high serum enzyme levels attributed tomuscle cell injury in Duchenne's muscular dystrophy(DMD). The present studies were undertaken to de­termine if this effect of DES could be attributed to areduction in the efflux of enzymes from isolated mouseskeletal muscle, and to develop a model system for therational assessment of other potentially useful com­pounds. Thirty-four male mice were used. Half receiveddaily subcutaneous injections of ten J.Lg diethyl­stilbestrol-diphosphate (DES-DP) in saline for up tothree weeks; the other half received daily saline in­jections. The left gastrocnemius was isolated from con­trol and treated mice, and placed in separate incubationsolutions at 37°C. The efflux of creatine phosphokinase(CPK) and lactate dehydrogenase (LDH) from each wascompared over a four- to five-hour period.In 15/18 studies, there was a reduction in efflux of bothenzymes from muscles isolated from DES-DP treatedmice. The greatest effect was noted during the secondhour, when the mean efflux of each enzyme was reducedby approximately thirty percent. Minor differences inmuscle weight, water content and enzyme activities didnot explain the reduced efflux. Autoradiographic studiesusing H3DES showed intracytoplasmic accumulationwithin the mouse skeletal muscle. The results suggestthat DES or one of its metabolites localized in skeletalmuscle, and reduced enzyme egress by either reducingmuscle cell permeability or enhancing intracytoplasmicstability of the enzymes.This is the first compound given in vivo which has beenshown to reduce the spontaneous enzyme efflux fromisolated skeletal muscle. It remains to be established thata similar effect accounts for the serum enzyme reductionobserved when DES is administered to persons withDMD. Nevertheless, the use of this model has made itpossible to identify other agents that suppress the en­zyme leakage, and with molecular modeling is providinginsight into the molecular characteristics which influenceenzyme leakage.The QT Interval in Myocardial InfarctionRobert DoroghaziSponsor: Dr. Rory ChildersDiscussant: Dr. Morton ArnsdorfThe QT interval of the electrocardiogram represents thetime required for ventricular activation and recovery.The corrected QT duration and depth of T wave inver­sion were measured in sequential EKGs in 71 enzyme­proven myocardial infarctions seen at Billings Hospitalfrom 1974 to 1976. Ralph KunclSteven LukesAnthony MeyerNancy Olsen Robert LowRobert MarcincinGeorge Moll, Jr.Ronald Pearl17The results show that both the QT interval and the Twave undergo an orderly sequence of change in the daysfollowing myocardial infarction and that the time coursesof these changes are similar. QT prolongation is maximalin all infarctions on the second day. T wave inversion ismaximal at two and three days post-infarction in non­transmural and transmural infarctions respectively.These changes were more marked in non-transmural in­farction. Regardless of the magnitude of QT prolonga­tion, all observed QT intervals had returned to normal bythe sixth day post-infarction.The data suggest that QT prolongation later than sixdays following myocardial infarction is not intrinsic to theinitial event and another cause should be sought.The dangerous period of" electrical instability" follow­ing acute myocardial infarction has hitherto beenexamined only in terms of the statistical occurrence oflife-threatening rhythm disorders. This study provides ayardstick by which it can be measured in the clinicalEKG.Alkaline Phosphatase in lymph and Serum afterBile Duct ligationStephen C. HauserSponsor: Dr. Alfred L. BakerDiscussant: Dr. Martha L. WarnockPrevious studies have demonstrated that bile duct liga­tion produces a marked increase in alkaline phosphatase(A P) in serum and that this increase is dependent on newprotein synthesis by the liver. The purpose of this in­vestigation was to determine whether hepatic AP entersthe serum directly through the hepatic sinusoids or byway of the space of Disse and the thoracic duct. Tenmale Sprague-Dawley rats weighing 250 -350 gramsunderwent thoracic duct cannulation proximal to the cis­terna chyli: five of these also underwent bile duct liga­tion. Blood samples and cumulative thoracic duct lymphwere collected hourly for twelve hours. AP was de­termined by a modified Bessey-Lowry method.AP did not rise at any time point in lymph, but wasmarkedly increased in serum by seven hours when com­pared with control (p < .05), and continued to rise for thenext five hours. Electrophoresis of serum specimens onpolyacrylamide gel showed increasingly intense stainingof the hepatic isoenzyme throughout the study period.Lymph flow averaged 0.6 ml. per hour and did not changesignificantly in either group. Gastric instillation of cornoil led to a five-fold increase in thoracic duct lymph APfive hours after treatment. Molecular weight for sera APfrom bile duct-ligated rats was determined by gelchromatography and found to be approximately 125,000.Thus, hepatic AP molecules probably pass freelythrough the large openings in the sinusoidal endotheliallining and are transported out of the liver chiefly insinusoidal blood, which flows more rapidly than doeshepatic lymph.18 Monitoring the Monitors: Problems of Trace GasMonitoring in the Operating RoomLinda Lee HugheySponsor: Dr. Donald BensonDiscussant: Dr. Jacobus MostertThe issue of trace gas exposure in the operating room hasdemanded a newly-prominent niche in the professionalliterature. The portable infrared trace gas analyzers nowcommercially available are, the manufacturers claim,both inexpensive and accurate. To assess the impact oftrace gas monitoring on anesthetic practice, we comparedthe measurements of two portable nitrous oxide monitorsand observed the reactions of operating room personnelto the practice of monitoring.Ambient levels of 30 -60 parts per million or more ofnitrous oxide were recorded in standard operating rooms.Simple measures of tightening leaking valves and con­necting waste gas sources to outside vents with plastictubing minimized the worst leak sources. Serious techni­cal problems plague the monitors tested, namely inter­ference by other gases, calibration inaccuracy, and driftof the gauges.Theoretical problems of monitoring are even more crit­ical. Studies attempting to demonstrate dangers of tracegas exposure and to establish acceptable levels aresuggestive but flawed and often contradictory. Educatingoperating room personnel to the subject of trace gas ex­posure poses a second problem. Finally, a surprisingamount of antagonism to the concept of trace gasmonitoring exists, often among the very people at highestrisk of exposure. Such antagonism will make the initia­tion of a trace gas monitoring system difficult to fund andoperate until those who make operating room policy de­cisions are satisfied that reduction of trace gas levels inthe operating rooms is necessary.Determinants In Survival from Malignant Mela­nomaDavid KapelanskiSponsors: Drs. George E. Block and Michael KaufmanDiscussant: Dr. Andrew ChurgThe goal of orthodox operative treatment for Stage Imalignant melanoma is excision of all neoplastic tissue.In over half of the patients, this goal will be accomplishedby a wide excision of the primary tumor withoutlymphadenectomy. Elective lymph node excision istheoretically capable of improving the survival rate byremoving the occult metastases while they are amenableto cure. The low incidence of occult nodal metastases(14.8 percent in this series) and the disappointing survivalwhere nodal disease is encountered (20 percent) requirethe establishment of parameters capable of discriminatingthose patients liable to benefit from such intervention.Clark's and Breslow's histologic staging methods haverecently been advocated as discriminate criteria. In a re-trospective analysis of 114 cases of Stage I and II malig­nant melanoma seen at the University of Chicago, thefive-year recurrence-free survival was 76.9 percent forClark level two, 56.3 percent for level three, 36.4 percentfor level four, and 37.5 percent for level five. The five­year recurrence-free survival was 74.2 percent for pri­maries less than 1.50 mm. thick, and 41.9 percent forprimaries larger than this. Elective regional node dissec­tion significantly improved recurrence-free survival onlyfor level four primaries (p < 0.025). There was no sig­nificant difference in survival when local excision andlocal excision plus elective node dissection were com­pared for level two, three, or five. The histologic type ofthe primary tumor did not significantly alter survival.Primary lesions were also examined for: a) ulcerationgreater than 6 mm.; b) perineural, vascular, or lymphaticinvasion; and c) one or more mitotic figures per highpower field. The absence of these characteristics was as­sociated with a 72.7 percent five-year survival. The pres­ence of one characteristic was associated with 48.1 per­cent survival, two characteristics with 26.7 percent sur­vival, and three characteristics with a 14.3 percent survi­val (p < 0.05).The inability of currently-employed criteria to uni­formly predict recurrence, and the technical imprecisionof the criteria due to sampling and observer error, whencombined with the high proportion of treatment failure,mitigate against the use of these criteria to select patientsfor an elective operative procedure of limited efficacy.Calcium Oxalate Urolithiasis: An Approach toUnderstanding the Crystallization ProcessJohn W. KareshSponsor: Dr. William GillDiscussant: Dr. Frederic CoeCrystallization of calcium oxalate from urine with reten­tion of the crystal in the papillary duct is the fundamentalprocess involved in the development of stones.Stud y of crystallization theory, the molecular basis ofstone formation, can help us to further understand thefactors involved in stone formation.We have investigated the following pertinent ques­tions:1. Under what conditions will a urine spontaneouslyform calcium oxalate crystals? (the concept of nucleationand the metastable limit),2. How much calcium oxalate will precipitate? (thesupersaturation level), and3. How fast will the precipitate form? (the crystalliza­tion rate).We have been able to study these questions in a sim­plified system, by developing a technique for the produc­tion of solutions supersaturated at various levels withradioactively-labelled calcium oxalate in a simple and re­peatable manner. These studies have shown that themetastable limit and saturation level are increased, andthe crystallization rate slowed, in water which containssmall ions similar to those found in urine. These results have been extended by studying urinesdialyzed, with macromolecules removed. The mac­romolecules affected calcium oxalate crystallization by:an inhibition of nucleation (increased metastable limit),an inhibition of the crystallization rate, a decrease in thesupersaturation level, and a decrease in adhesion of crys­tals to container surfaces.These results have been further extended by studyingurines from normal humans and from those who formstones. In those who form stones the relative level ofsupersaturation with calcium oxalate tends to be higherand the rate of crystal formation faster than in normals.The stone formers seem to have a poorer protectivemechanism against crystallization in urine.The importance of crystallization theory in the evalua­tion of the stone former and in possible therapies is evi­dent.The Effect of Anesthesia on Renal Hemodynamicsin the RatBruce M. KoeppenSponsors: Drs. Adrian I. Katz and Marshall D. Lind­heimerDiscussant: Dr. Harold L. BrooksRadioactive microspheres have been used extensively inthe study of intrarenal hemodynamics following numer­ous physiologic, pathophysiologic and pharmacologicmanipulations. The majority of these studies have beenperformed in the anesthetized dog. However, recentwork in the dog and in the rabbit has shown that anes­thesia itself alters intrarenal hemodynamics. In the pres­ent study we have adapted the microsphere technique tostudies in the rat, and have determined the effect of anes­thesia on renal hemodynamics in this species.Experiments were performed on female Sprague­Dawley rats weighing 180-220 grams. The animals werestudied either unanesthetized (U) or anesthetized withsodium pentobarbital (P) 50mglkg I. P., or with Inactin (I)120mglkg I.P. Total renal blood flow (RBF) and its intra­renal distribution were determined with Sr-85- and Ce-141-labeled microspheres 15 ± 51L in diameter. RBF wascalculated by a modification of the Fick principle, andcortical distribution was determined for three 500IL zonessliced on a clinical microtome (Zone I = outer cortex,Zone II = mid-cortex, Zone III = inner cortex).RBF(rnl/rnin/g K.W.) %ZONAL DISTRIBUTIONI II IIIU 7.16 43.0 33.6 23.4n= 12 ±.49 ± 1.3 ±1.2 ± 1.1P 4.75c 37.7a 36.0 26.3n=l1 ±.42 ±2.1 ± 1.4 ±1.0I 5.43 b 42.8 33.8 23.4n=13 ±.49 ± 1.7 ± 1.5 ± 1.2(mean ± S.E.M.) a = p < .05; b = p < .025; c = p < .00519The results indicate that both pentobarbital and lnactinanesthesia cause a decrease in renal blood flow, and thatpentobarbital also produces a redistribution of blood flowaway from the outer cortex. These observations under­score the need for caution in interpretation of mea­surements of renal hemodynamics obtained in anes­thetized animals.Lesions of the MyofibrilRalph W. KunclSponsors: Drs. Herbert Y. Meltzer & Ward R. RichterDiscussant: Dr. Louis CohenOne of the disappointments of the myopathologist is thefact that the pathologic reaction of skeletal muscle toinjury is limited, and most of what he sees is non-specific.There are two commonly-occurring myofibrillar lesionswhich are of obscure origin; the lesions are (1) patchyareas of disruption of normal myofibrillar banding, and(2) patchy areas of smearing of the dense Z-band. Theseare extremely common lesions occuring in non-necroticcells in a wide variety of either neurogenic or myogenicneuromuscular diseases. They are not seen on routinelight microscopic preparations of tissue but are seen onthin and ultrathin sections in the phase microscope orelectron microscope.I studied the occurrence of these lesions in an experi­mental myopathy in which such lesions commonly occur,and in which they are essentially the only significantpathologic change. The myopathy is produced by re­straining rats after pretreating them with a psychomotorstimulant. The extent of myopathy is related to theamount of isometric exercise of the constantly strugglinganimal. This study is an attempt to analyze thesecommonly-occurring myofibrillar lesions quantitativelyand qualitatively as they develop over time and in severalmuscle groups. It corrects some misconceptions concern­ing the pathogenesis of myofibrillar lesions and sub­stantiates an important pathogenic role of the mitochon­drion.The predominant lesion in the experimental myopathywas extensive myofibrillar disruption, occurring in50 -60 percent of fibers. This lesion was temporally re­lated to the 30-fold increased plasma CPK activity thatbegins within minutes of treatment. Focal mitochondrialloss occurred subsequent to other mitochondrial abnor­malities within areas of myofibrillar disruption. Initially,myofibrillar disruptions contained disoriented, clumped,abnormally-staining mitochondria with changes in thefine structure of the cristae. Only 24 hours after onset ofmyofibrillar disruption were mitochondria typically lostin disrupted foci. This correlated well with a 40 percentreduction in specific mitochondrial activity of succinatecytochrome C reductase (SCR) soon after treatment anda recovery of normal specific SCR activity at 24 hours.Significant Z-band smearing occurred independently ofmyofibrillar disruption, being noted first at 24 hourstreatment.Both myofibrillar lesions also occur in normal un­treated control muscles. In control muscles of the lower20 limb, Z-band smearing occurred predominantly inmitochondrial-rich (red) fibers; to the contrary, myofibril­lar disruption occurred predominantly in mitochondrial­poor (white) fibers. In both experimental and untreatedmuscle, Z-band smearing occurred predominantly inthose specially-differentiated peripheral areas in themuscle fiber which are immediately adjacent totransversely-coursing blood vessels. These areas nor­mally lack mitochondria.Thus, the focal mitochondrial/ass that occurs in areasof myofibrillar disruption is not of the same significanceas the focal mitochondrial absence in areas of Z-bandsmearing. In the former lesion, focal mitochondrial de­gradation is an early concomitant and focal mitochondrialloss a subsequent event to the myofibrillar lesion; in thelatter lesion, focal mitochondrial absence provides astructural substratum for the occurrence of a Z-band ab­normality.Myofibrillar lesions are common in normal and dis­eased skeletal muscle. In normal muscle, they may rep­resent a mechanism for myofibrillar turnover and con­sequent muscle fiber remodeling which is known to occurfollowing change in muscle usage and innervation pat­terns. In diseased muscle, myofibrillar disruption may becommon because it represents a final common responseto mitochondrial injury from many causes, in this casemitochondrial injury by functional hypoxia. In support ofthis mechanism are the similarity of this myopathy toexperimental ischemic myopathy and the fact that it isblocked by denervation, adrenal demedullation, andbeta-adrenergic receptor blockade-all maneuvers thatreduce the oxygen requirement of the muscle cell.Z-band lesions may be common because they occur spe­cifically in those frequent subcellularly-differentiatedareas of the muscle fiber which are particularly suscepti­ble to injury due to a paucity of mitochondria.Perhaps study of the skeletal muscle mitochondria inthose neuromuscular diseases of obscure etiology inwhich myofibrillar lesions commonly occur will be re­vealing.Bacillus Subtilis DNA Polymerase III and ItsNovel Inhibition by the 6-p-hydroxy­phenylhydrazinopyrimidinesRobert L. LowSponsor: Dr. Nicholas R. CozzarelliDiscussant: Dr. Wolfgang EpsteinAlthough DNA polymerase III is necessary for DNAreplication, prior to this study it had not been charac­terized adequately. Bacillus subtilis ON A polymerase IIIwas purified 4500-fold to near homogeneity and shown tobe a highly-asymmetric protein consisting of a single165,000 dalton polypeptide. In addition to the polymeraseactivity, the enzyme promotes phosphorolysis of DN Aand contains a potent, intrinsic exonuclease activity. Theexonuclease non-processively degrades single-strandedDNA from the 3' terminus yielding 5'-mononucleotides.Maximal activity occurs on short chains. The exonuc-lease activity probably functions to remove mismatchedbases inadvertently incurred during replication.The 6-p-hydroxyphenylazopyrimidines are anti­microbial agents against a wide variety of gram-positiveorganisms. They selectively inhibit DNA replication andDNA polymerase III. Polymerase III was purified froma drug-resistant B. subtilis mutant and shown to be re­sistant in vitro, conclusively demonstrating that the en­zyme is the drug target in vivo. The molecular mechanismof drug inhibition has been determined. The reduced, ac­tive hydrazino form of the uracil drug derivative interactsat the enzyme's nucleoside triphosphate binding site, andsimultaneously hydrogen bonds to a template cytosine,adjacent to the primer terminus of the DNA. Thepolymerase is thereby sequestered into an inactiveDNA-drug-polymerase ternary complex.The ternary complex was isolated by agarosechromatography and shown to have the predicted fea­tures. The arylhydrazinopyrimidines are the best under­stood and most specific ON A replication inhibitorsknown. The ternary scavenging mechanism suggests thatsimilar drug analogues might be designed to inhibit otherpolymerases and thereby provide new avenues of selec­tively inhibiting DNA synthesis.Hemodynamic Effects of Sodium Nitroprussidein Severe Congestive Cardiac FailureSteven A. LukesSponsors: Drs. Leon Resnekov and Calixto RomeroDiscussant: Dr. Jafar AI-SadirSodium Nitroprusside (NP) is a systemic vasodilator thathas recently been used in attempts to improve cardiacfunction by decreasing left ventricular afterload. Underclose hemodynamic monitoring, NP was administered tosixteen patients with severe congestive cardiac failure.Ten patients (responders) demonstrated marked im­provement in clinical and hemodynamic parameters. Sixpatients (nonresponders) demonstrated no overall im­provement, despite transient benefit in four. Initial leftventricular filling pressure (LVFP) was higher in the re­sponder than in the nonresponder group (37 ± 3 vs. 27 ±1 mm Hg, p < 0.025), as was systemic vascular resistance(SVR) (2510 ± 150 vs. 1730 ± 250 dynes-sec-em - 5, p <0.05). All ten responders had SVR greater than 1900dynes-sec-em -5, while five of the six nonresponders hadSVR less than 1800. Thus, SVR and L VFP appear to behelpful in predicting the response to NP infusion in pa­tients with congestive failure.The Production of Single Digit Numbers by Sub­jects with Normal and Impaired Cognitive Func­tionRobert P. MarcincinSponsor: Dr. Charles M. CulverDiscussant: Dr. Robert Cohen A simple "paper and pencil" technique in which subjectsgenerate sequences of single digit numbers is describedand investigated as a potential test of a patient's mentalstatus. The task is different from most tests of cognitivefunction in that it requires a sustained production of in­formation output with no given conceptual structure inwhich to operate. Hence, it might prove sensitive to evenmild degrees of cortical dysfunction.This study contrasted the ability of subjects with mildcognitive impairment and a matched group of unimpairedcontrols to perform the number generation task.Twenty-four subjects were assigned to each group on thebasis of standardized neuropsychological test results.They were matched for sex, age, and level of education;all were judged to be without focal neurological deficits.Subjects were given a paper and pencil and asked torandomly write as many single digit numbers as possiblein a two-minute period. Each SUbject's data output wasanalyzed with a series of computerized tests that wereconstructed to measure diverse properties of a numberseries.The results indicate that the two groups differ sig­nificantly on several parameters of their number produc­tion. Subjects are seen to create patterns in their numberseries that are group specific.These findings demonstrate that the test is sensitive tomild degrees of cortical dysfunction. Criteria for correctinterpretation of results of the test and proper classifica­tion of patients are developed.The Development of Immune Reactivity toTumor in Immunized and Non-Immunized MiceAnthony A. MeyerSponsors: Drs. Robert L. Hunter and Robert W. WisslerDiscussant: Dr. Warren E. EnkerThis project was undertaken to study how the immuneresponse to a tumor changes with time and tumor growth.It also investigated the effect of pre-immunization onhow this response changes. The MKS-TU5 tumor sys­tem in Balb/c mice was used for this study because of itsstrong immunogenicity. Initial experiments characterizedthe tumor system with respect to the rate of growth oftumor and the dose of irradiated cells required for suc­cessful immunization.Next, three assays of immune reactivity were selectedand standardized for this system; they were blast trans­formation, the Winn test, and lymphoid and tumor tissuemorphology.With the preliminary studies accomplished, the devel­opment of immune response to tumor was investigated.Animals received tumor transplants and the growth oftheir tumors was followed. The growth period could bedivided into three phases, an initial phase of slow growth,followed by a phase of rapid growth, and a final phase ofreduced growth when the animals approach death. Ani­mals with tumors in each of these phases were selectedrandomly, sacrificed, and studied using the three testsmentioned previously.21Analysis of the results revealed that animals demon­strated increasing, significant reactivity to their tumorseven in late phases of tumor growth as measured by allthree tests. In the blast transformation data was revealeda loss of reactivity during the phase of rapid tumorgrowth, but this was temporary.Animals immunized prior to tumor transplant werestudied in the same manner. Immunized animals who re­jected tumor grafts had immune reactivity that rose morerapidly than that of non-immunized animals. However,those immunized animals who failed to reject theirtumors also failed to demonstrate a significant rise in im­mune reactivity to the tumor.The results of this study reveal two major points. First,the immune response to tumor can continue to increasewhile the tumor grows rapidly. This indicates that insome clinical situations induction of tumor immunity in apatient may have no effect on his cancer. Second, in­adequate immunization may not only fail to protect thehost, but also may prevent the development of an im­mune response to tumor. Such effects would have to beconsidered in a vaccination program for cancer preven­tion.This study has provided some useful information aboutthe development of immune reactivity, but it has raisedmore questions and hopefully can serve as a basis fortheir investigation.A Bovine Brain Protein Kinase: An Analysis ofProtein Kinase Mechanism and StructureGeorge W. Moll, Jr.Sponsor: Emil T. Kaiser, Ph.D.Discussant: Josef Fried, Ph.D.The cAMP-dependent protein kinases have been im­plicated as the primary mediators of intracellular cAMPaction. They are thus suitable for the study of the molecu­lar mechanism of action of cAMP.Our preliminary studies of the bovine brain cAMP­stimulated protein kinase suggested a covalent cAM P­enzyme intermediate, but the available methods for pur­ification yielded an enzyme preparation which was in­adequate for detailed mechanistic studies. A procedurewas devised which yielded two highly purified cAM P­stimulated bovine brain protein kinases, one of whichwas stable (PKI) and another less stable (PKII). Noother protein kinases or cAM P-binding subunits wereisolated. The molecular weight of PKI was 162,000 ± 7percent and that of PKII was 83,000 ± 7 percent MWdetermined by gel filtration, analytical ultracentrifuga­tion, and amino acid analysis. SOS gel electrophoresisindicated single sub-unit molecular weights of 73,000 forPKI and 85,000 for PKIl.The data suggested that PKI was formed from twoPKII species and might be the first cAMP-stimulatedprotein kinase with both catalytic and regulatory activityon the same protein subunit. A new protein kinase assayemploying PEl-cellulose thin-layer sheets was devisedwhich permitted 14C-labelled ATP to be used for the first22 time as a protein kinase substrate. This assay was ofgreat help in elucidating the mechanism of action of PKI.The inhibitory effect of metal ions commonly found inprotein kinase assays fits a general ionic strength inhibi­tion model for PKI phosphorylation of histone. Theseexperiments set the stage for future studies concerningthe molecular interaction of cAMP with PKI, and raisesome interesting points regarding the enzymatic mechan­ism of protein kinases in general.The Development of Cell-Mediated Immunity inMice with Mammary TumorsNancy J. OlsenSponsor: Dr. Robert HunterDiscussant: Dr. Warren E. EnkerHuman breast cancer has been shown to be associatedwith various immune responses. The development ofcell-mediated immunity was studied in the C3HBAmouse mammary tumor system. Antigens were preparedfrom mouse and human tissues by the method of KClextraction. Spleen cells from tumor-bearing mice wereused in two in vitro assays of cell-mediated immunity:inhibition of the migration of macrophages and stimula­tion of lymphocyte blastogenesis.U sing the agarose droplet method of MIF assay, anti­gen-specific inhibition of cells from C3HBA mice wasobserved. In addition, antigenic stimulation of spleencells from immunized mice resulted in the production ofMIF activity. In the blast transformation assay, cellsfrom C3 H BA mice had depressed responses to the mito­gen Concanavalin A. A peak of blast activity in responseto antigenic stimulation occurred six to seven weeks aftertumor transplant. Mice who received antigen immuniza­tion prior to tumor challenge had higher stimulation in­dices in this assay.An in vivo assay in mice compared the effects of im­munization with the KC 1 extracts. The normal humanbreast extract inhibited tumor growth, while extract of ahuman breast tumor enhanced the lethality of theC3HBA tumor.The human and C3HBA tumors appear to share anti­gens, morphology and immunological mechanisms. TheC3HBA tumor is a model for the study of human breastneoplasms which may further elucidate immunologicmechanisms in this disease.The Existence of Tolerance to and Cross­Tolerance between {i-Amphetamine andMethylphenidate in the RatRonald G. PearlSponsor: Lewis S. Seiden, Ph.D.Discussant: Dr. Charles R. SchusterAdministration of {i-amphetamine (2.5 mg/kg) or methyl­phenidate (20 mg/kg) decreased milk consumption in rats.When these drugs were administered daily, tolerance de-veloped to this effect over the course of 20 days. Cross­tolerance to the effects on milk consumption occurredbetween g'-amphetamine and methylphenidate over a4-fold range of dose of both drugs. Administration ofg'-amphetamine (l.5 mg/kg) or methylphenidate (10mg/kg) disrupted responding under differential­reinforcement-of-low-rate (DRL) contingencies. Bothdrugs increased response rate, decreased frequency ofreinforcement, and shifted the mode of the interresponsetime distribution to the left. When the drugs were ad­ministered daily, tolerance developed to all these effectsover the course of 20 days.Cross-tolerance to the effects on DRL behavior oc­curred between g-amphetamine and methylphenidateover a 4-fold range of dose of both drugs. Daily adminis­tration of d-amphetamine (2.5 mg/kg) but not of methyl­phenidate (20 mg/kg) resulted in decreased norepine­phrine levels in brain; the decreased norepinephrinelevels which occur with repeated £i-amphetamine ad­ministration are believed to result from the storage innoradrenergic neurons of p-hydroxynorephedrine, ametabolite of g-amphetamine. Radioactivity was not de­tectable in rat brain 24 hours after the last of 15 dailydoses of radio-labeled methylphenidate.These results suggest that g'-amphetamine, but notmethylphenidate, is metabolized to a compound which isstored in noradrenergic neurons. The existence of behav­ioral cross-tolerance between £i-amphetamine andmethylphenidate is therefore inconsistent with thehypothesis that tolerance to the behavioral effects of£i-amphetamine is due to the metabolism ofg'-amphetamine to p-hydroxynorephedrine, a falsetransmitter in noradrenergic neurons.Lead Encephalopathy: A Study of Altered Vascu­lar Growth, Capillary Permeability andNeuronal Development in an Animal ModelMichael F. PressSponsor: Winston Anderson, Ph.D.Discussant: Dr. Edward GanzLead encephalopathy was produced in neonatal Long­Evans rats by administering daily doses of lead acetate(600 milligrams of lead acetate per kilogram of bodyweight) through an esophageal catheter. Experimental ratpups showed behavioral changes, failed to gain weight atthe same rate as controls, developed a paraplegia, anddied by fifteen days of age. Lead analysis showed veryhigh blood and tissue lead levels.Sequential histopathologic changes were studied in thecerebellum at the light and electron microscopic levels.Observations were also made in the choroid plexus,cerebral cortex and corpus striatum. In the cerebellum,petechial hemorrhages were present at three days, at fivedays extensive hemorrhagic lesions were observed, andthereafter until death there was a progressive accumula­tion of fluid in extracellular spaces.Developmental changes in cerebellar neurons wereexamined in Golgi preparations and by electron micro- Michael PressDavid SalesBurton Vander LaanRichard Walker Alan RushtonJohn Scarlett IIISherwin WaldmanJack Weiss23scopy. Matrix cells and neuroblasts of the external granu­lar layer were minimally altered prior to day eight, butthereafter the number of mitotic figures per folium de­creased moderately and the number of pyknotic cells in­creased markedly. Purkinje cells survived the cerebellaralterations of lead encephalopathy well for the first five toeight days. However, the rate of Purkinje cell maturationover "edematous cavities" was retarded after ten days.Vascular malformations were studied with electronmicroscopy, ultrastructural tracers (horseradishperoxidase) and Golgi preparations. Functional andmorphologic alterations were observed in the developingendothelium as early as three days of age. The evidencesuggests that growing capillaries (angioblasts) are a pri­mary central nervous system structure damaged by leadintoxication.Genetic Linkage Studies of the Human Glvco­sphingolipid ,B-GalactosidasesAlan R. RushtonSponsors: Drs. Glyn Dawson, Albert Dorfman, and JanetRowleyDiscussant: Dr. Allen L. HorwitzGlycosphingolipids are important membrane compo­nents of all eukaryotic cells. They also occur as the majorstorage material in a number of inherited human lipidstorage diseases. Galactosylceramide (Gal (,BH I) Cer)is stored in Krabbe's disease; lactosylceramide (Gal (,Bl-74) GIc (,BH I) Cer) accumulates in lactosylceramidosis;and the ganglioside GMI (Gal (,B1� 3) GalNAc (,B1� 4)[NANA (ah 3)] Gal (,Bl-7 4) GIc (,Bl-7 I) Cer) is stored inGMI generalized gangliosidosis. Each of these disorders isinherited as an autosomal recessive and is characterizedby deficiency of a specific f3-galactosidase activity towardthe stored glycosphingolipid. These observationssuggested the existence of three human f3-galactosidases.The genetic linkage relationships of the human glyco­sphingolipid f3-galactosidases were determined using twoindependent series of human-mouse somatic cell hybrids.A new method was devised for the estimation of humanGalCer, LacCer and ganglioside GMI f3-galactosidase ac­tivities in the presence of their mouse counterparts,based on differences in both pH optima and sensitivity tochloride ion. A ratio was defined for each activity whichwas the specific activity at the human pH optimum di­vided by the specific activity at the mouse pH optimum.Hybrid cells containing both human and mouse enzymeswere expected to have pH ratios intermediate betweenthose characteristic of the human and mouse parentalcells. The pH ratios for f3-galactosidase activity towardthe three glycosphingolipids were determined in approx­imately twenty hybrid cell clones.Human and mouse chromosomes were identified inthese same hybrid cell lines by their characteristic band­ing patterns after staining with quinacrine mustard. Themethod of linear regression analysis was then used to testfor concordant segregation between pH ratios for eachf3-galactosidase activity and for the frequency of occur-24 renee of different human chromosomes in the human­mouse hybrid cell strains.The results from two independent series of hybrid cellclones indicated that human f3-galactosidase activitiestoward the three glycosphingolipids, GalCer, LacCerand ganglioside GMI, consistently segregated with humanchromosome C-12.Serum Apolipoprotein Abnormalities in DiabeticRatsDavid SalesSponsor: Dr. Godfrey GetzDiscussant: Dr. Arthur RubensteinDiabetics often have hyperlipidemia and prematureatherosclerosis. Rats rendered diabetic with streptozoto­cin injection developed hyperlipidemia associated withincreased levels of very low density lipoprotein (VLDL),characterized by a lower proportion of arginine-rich pep­tide and a higher proportion of apolipoprotein C-II (a poC-II) relative to apo C-III-O. This apo C abnormality wasfound in all sizes of VLDL as well as in HDL of diabeticrats, and treatment of the diabetic rats with insulin in vivoreversed these changes.To investigate the origin of the diabetic abnormalities,the synthesis, secretion and turnover of the apolipopro­teins of VLDL were studied. Isolated perfused liversfrom diabetic rats produced VLDL with apo C abnor­malities similar to those seen in their plasmas. Turnoverof the various apoproteins was unaltered. Thus, an ab­normal balance in the hepatic synthesis of VLDL apo­proteins probably accounts for the changes seen in dia­betes. Since the apo C's are regulators of lipoproteinlipase, these abnormalities may represent an adaptationto the defective removal of plasma triglycerides encoun­tered in diabetes.Diagnosis of Factitious Hypoglycemia by Mea­surement of Plasma C-Peptide Reactivity andInsulin-Binding AntibodiesJohn A. ScarlettSponsor: Dr. Arthur RubensteinDiscussant: Dr. David HorwitzSeven patients with factitious hypoglycemia due to thesurreptitious injection of insulin are described. The di­agnosis was made by measurements of plasma insulin andC-peptide immunoreactivity (seven patients) and wasfacilitated by the finding of circulating insulin-bindingantibodies (two patients). The simultaneous demonstra­tion of low plasma glucose, high immunoreactive insulinand suppressed C-peptide immunoreactivity represent atriad of results pathognomonic of exogenous insulin ad­ministration. Determination of plasma free C-peptide andfree insulin permitted insulin-requiring diabetic patientswith unexplained hypoglycemia to be studied and di­agnosed in a similar way to non-diabetic subjects.Prostaglandin Metabolism m MyeloproliferativeDiseaseBurton F. Vander LaanSponsor: Dr. Juan ChediakDiscussant: Dr. Margaret TelferPlatelet aggregation as a diagnostic tool is being in­creasingly utilized in both routine and research labora­tories, and several new agents capable of inducing thisresponse have recently been described. One such sub­stance is arachidonic acid, which acts via conversionwithin the platelet to certain prostaglandin metabolites.Since the response can be correlated with the levels ofvarious prostaglandin metabolites, it seems that thesesubstances are responsible for the in vitro platelet aggre­gation.In studying platelet aggregation in various conditions,it became evident that platelets from patients withmyeloproliferative disorders behaved differently thannormal platelets. Since the exact pathogenesis of thehemostatic defects in these patients is unknown, a studywas undertaken of the platelet function and prostaglandinmetabolism in these disorders. One such patient exhaus­tively studied had a significant bleeding tendency as wellas a refractory anemia, neutropenia and thrombocytosis,and illustrated that the abnormality may reside in an in­effective production of prostaglandin metabolites withinthe platelet. Initial evaluation showed a prolonged bleed­ing time, abnormal platelet aggregation, abnormalplatelet electron microscopy and deficient 14C_ serotoninrelease. Measurements of one of the main prostaglandinmetabolites, malondialdehyde, disclosed reducedamounts, and platelet adenine nucleotides were at thelower limit of normal. Similar results were obtained in agroup of controls following the ingestion of aspirin,known to interfere with prostaglandin synthesis.It is possible to speculate that patients with myelo­proliferative disorders produce an abnormal clone ofplatelets defective in the synthesis of prostaglandins, thusexplaining the bleeding tendency or the in vitro abnor­malities observed.Changes in Venular Resistance by Sticking WhiteBlood Cells in Hemorrhagic Hypotension­Effects of Heparin, Methyl Prednisolone, Dex­tran 40 and Normal SalineSherwin WaldmanSponsors: Drs. Robert Replogle and Elof ErikksonDiscussant: Dr. Gerald MossIn hemorrhagic shock, the increased vascular resistancedue to vasoconstriction is well described. The contri­bution to the vascular resistance by wall-adhering whiteblood cells (WBCs) is less appreciated. In this study,using in vivo microscopy, it was attempted to quantitatethe contribution of sticking WBCs to venular resistance.In anesthetized rats, the exposed mesentery was ob­served in the microscope. The femoral artery and vein were cannulated for blood pressure measurements andintravenous injections. The number of sticking WBCswas counted in a venule of approximately 25 ILm diame­ter and 215 ILm length, before and after the rat was bledby 30 percent of its total blood volume, and at subsequentadministration of different pharmacological agents. Dur­ing control conditions, 1-2 WBCs adhered, and afterbleeding, 8.When heparin (200 IU/kg) was given following hemor­rhage, the number increased to 11, while the administra­tion of methyl prednisolone (30mg/kg) after hemorrhageresulted in a decrease to 4. Neither dextran 40 (50 percentof bled volume) nor saline (150 percent of bled volume)affected WBC adherence. Theoretical calculations re­vealed a 400-fold increase in venular resistance caused bythe adherent WBCs.Control of local Cerebral Blood Flow by CentralAdrenergic MechanismsRichard H. WalkerSponsor: Dr. Jack de la TorreDiscussant: Dr. John MullanThe cerebral vasculature consists of two systems: extra­parenchymal and intraparenchymal vessels. Extra­parenchymal vessels are known to be innervated by theperipheral sympathetic system via the superior cervicalganglion.Histofluorescence of catecholamines was used to dem­onstrate adrenergic varicosities on forebrain intra­parenchymal arterioles in dogs and monkeys havingundergone bilateral superior cervical ganglionectomy.This finding suggests intraparenchymal microvessel in­nervation by a central adrenergic system, presumablyoriginating in the brain stem locus coeruleus and project­ing rostrally via the ipsilateral noradrenergic dorsal teg­mental bundle, with little or no contralateral crossover.To study the effect of unilateral electrical stimulationof the locus coeruleus on local cerebral blood flow bilat­eral pre-stimulation and post-stimulation blood flow re­cordings using hydrogen clearance were made stereotaxi­cally in three discrete forebrain regions in rats havingundergone bilateral superior cervical ganglionectomy.Post-stimulation flow recordings showed: 1) a mean re­duction in local cerebral blood flow of 40, 65, and 70percent from pre-stimulation baseline flow rates in fore­brain regions ipsilateral to stimulation and 2) no sig­nificant change from pre-stimulation flow rates in fore­brain regions contralateral to stimulation.The mechanism suggested by this evidence is that elec­trical stimulation of an adrenergic center, the locuscoeruleus, can affect catecholamine release at adrenergicterminals located on ipsilateral intraparenchymal fore­brain microvessels in the regions studied, and causealteration of local cerebral blood flow. Other studies haveshown that pharmacologic stimulation of the locuscoeruleus with carbachol causes reduced cerebral bloodflow and that alpha receptor blockade with intra­ventricular phentolamine causes increased flow.25Knowledge of the mechanism of regulation of cerebralblood flow is applicable to treatment of head injury andcerebral vascular insult in humans.Transmural Distribution of Ischemia: Variationin Canine and Porcine HeartsJack L. WeissSponsor: Dr. Harold L. BrooksDiscussant: Dr. John J. LambertiThe transmural distribution of blood flow before and dur­ing regional ischemia was compared in canine and por­cine hearts-two animal models currently in wide use formyocardial infarction studies. Open-chest, chloralose­anesthetized dogs (10) and pigs (16) of comparable heartsize were studied. Technecium-99m-labeled albuminmicrospheres (1.0-1.5 million, 15-30 J.L) were injectedinto the left atrium and allowed to circulate for 30 sec­onds following occlusions of arteries of varying sizes.The heart was excised, quickfrozen, and the ventriclescut into 1.0 ern" pieces, with each piece sectioned intoepicardial (Epi) and endocardial (Endo) halves. Trans­mural blood flow gradients were expressed in terms ofEpiJEndo flow ratios.No significant transmural flow gradient was demon­strated across the canine left ventricular free wall, eitherin the control (1.15 ± .15) or the ischemic (1.04 ± .19)state. In contrast, the porcine left ventricular free walldid yield a significant transmural blood flow gradient atthe 0.05 level of significance both at control (0.81 ± .04)and following two minutes of ischemia (0.51 ± .05).Hemodynamic parameters were comparable in bothspecies.The resting flow patterns can be explained by previousanatomical studies which have shown the canine heart tohave extensive, predominantly epicardial interarterialanastomoses while the porcine heart, similar to that ofthe human, has fewer anastomoses which are locatedprimarily in the endocardial layer. Anatomy of the coro­nary collaterals may also be the determining factor in thetransmural distribution of ischemia.SENIOR SCIENTIFIC SESSION WINNERSTwo awards were presented to students for theirexceptional presentations at the Senior Scien­tific Session.

WisslerDiscussant: Dr. John L. SkoseyRecent experimental evidence suggests that lysosomesplay an important role in the accumulation of lipid in theatherosclerotic plaque. This study attempts to explorethe relationship between lysosomal enzymes and thesmooth muscle cellular proliferation observed in humanatherosclerosis as well as in experimental models utiliz­ing "conditioned media."Human blood was used to prepare whole blood serum(WBS), platelet-rich plasma serum (PRPS), andplatelet-poor plasma serum (PPPS), which were thenanalyzed for alpha-mannosidase, beta-glucuronidase,acid phosphatase, cathepsin 0 and peroxidase activity.The WBS alpha-mannosidase activity was greater thaneither PRPS or PPPS, but the PRPS-PPPS differencewas not statistically significant. The order of beta­glucoronidase activity was WBS > PRPS > PPS (all dif­ferences being significant). WBS acid phosphatase wasgreater than PPS (WBS-PRPS and PRPS-PPS dif­ferences were not significant). No sample showed dis­cernible cathepsin 0 or peroxidase activity."Conditioned media" prepared with monkey blood in­cluded five percent WBS, five percent PPS and five per­cent PRPS with a supernatant of granulocytes incubatedwith zymosan (ZIG). Rabbit blood was used to prepare amacrophage-conditioned media (MCM). Order ofalpha-mannosidase activity was MCM > WBS > PPPS> ZIG. The order of beta-glucoronidase activity wasWBS > MCM > ZIG> PPPS. Assay of acid phos­phatase activity showed no difference between five per­cent WBS and five percent PPS. No sample showed ap­preciable cathepsin 0 or peroxidase activity.These results suggest that cellular elements as well asplatelets release lysosomal enzymes during in vitrocoagulation. The differences in enzyme activity of the"conditioned media" are also consistent with a role forlysosomal enzymes or their products in the stimulation ofin vitro cell growth.The old order changeth,yielding place to the new.-TennysonName Graduation YearHome Address TelephoneCity, State, ZipBusiness Address TelephoneCity, State, ZipTitleNew address?New position?New medical practice?military assignment?civic or professional honor?book?Please tear out; fold, staple, or tape; and drop in the mailbox.

They were joined by three other recentgraduates: one who graduated in December 1976, andtwo who graduated in 1974 but postponed their res­idencies while they engaged in research activities. Of thetwo graduating seniors who did not participate in theNIRMP, one will enter a residency in emergencymedicine which was not listed in the national matchingprogram, and the other intends to postpone his residencywhile he engages in graduate studies in physiology at theUniversity of Illinois. This brings the total number of ourgraduates who will enter residencies in 1977 to 98.One married couple in the graduating class arrangedfor their postgraduate clinical appointments prior to theactual matching process in a procedure that is permissiblefor married couples under N IRMP guidelines.Almost 90 percent (86) of the 97 individuals who parti­cipated in the national matching program received ap­pointments in residency programs which filled all of theirallocated positions in the NIRMP. Similarly, of the 68hospital units where these students began their residencyassignments on July 1, 85 percent (58) filled all of theirallocated positions in the NIRMP.Five students who participated in the matching pro­gram and were unmatched were subsequently placed inexcellent hospitals. In two instances, unmatched stu­dents were placed in hospitals-the University of OregonMedical Center and the Medical College of VirginiaHospitals-which had actually filled their quotas, butwhich had made additional spaces available subsequentto the matching. The other three unmatched studentswere placed in hospitals which had not filled all of theirallocated positions through the matching program. It issignificant that three of the five unmatched studentssought and secured residencies in internal medicine, adiscipline in which 87 percent of all residencies in theUnited States were filled by the NIRMP in 1977.All first-year postgraduate clinical appointments are now designated as residencies. There are three types offirst-year residencies: categorical, analogous to straightinternships in the past; diversified, analogous to mixedinternships in the past, with the major component beingin a specific clinical discipline; and flexible, similar toprevious rotating internships.The 98 University of Chicago graduates now beginningtheir residencies are distributed among the various disci­plines as follows: almost half-46-will be in internalmedicine, 18 will be in pediatrics, and 13 will be insurgery, including one in neurosurgery. Here is the com­plete distribution by clinical disciplines:Anesthesiology IEmergency Medicine 1Family Practice IFlexible 3Internal Medicine 46Neurosurgery IObstetrics and Gynecology 5Ophthalmology 1Pathology 5Pediatrics 18Psychiatry 2Radiology 2Surgery 12Total 98"The success of our students in the N I RMP can bedirectly attributed to the excellent cooperative efforts ofour students and our faculty members," says JosephCeithaml, Dean of Students. "The members of theCommittee on Residency Placement of Senior MedicalStudents, and Committee chairman Dr. RichardRothberg, should be commended for the time and effortthey expended on behalf of our senior medical students.Finally, the various departmental subcommittees­especially the one in medicine, since fully one-half of theclass sought residencies in internal medicine-meritpraise for their part in counseling the students on theirchoices of hospitals."Bronx Municipal H.

Hogness, Professor ofBiochemistry at Stanford University, de­livered the 1977 Howard Taylor RickettsAward Lecture on May 16. His topicwas "The Arrangement of Genes inDrosophila as Studied by RecombinantDNA."Hogness utilizes a recombinant ON Atechnique to insert fragmentary DNAfrom Drosophila melanogaster (the fruitfly) into small infective virus-like DNAmolecules called plasmids. These circu­lar hybrid plasmid-Drosophila are thenused to infect Escherichia coli bacteria.When theE. coli reproduce, the hybridplasm ids also multiply, producing largeamounts of one small piece of DrosophilaDNA that can be extracted from thehybrid DNA.Hogness utilizes this abundant sourceof Drosophila ON A fragments to studythe as yet unknown code for gene regula­tion.He is a member of the NationalAcademy of Sciences and the AmericanAcademy of Arts and Sciences, andserved in 1975 as a member of the Na­tional Institutes of Health AdvisoryCommittee on Recombinant DNA. Hewas recently appointed a member of thePresident's National Cancer AdvisoryBoard.He is the son of the late Thorfin R.Hogness, who was for many years Pro­fessor of Chemistry and Director of theInstitute of Radiobiology and Biophysicsat the University of Chicago.Quantrell Award for SwiftHewson H.

He served as chairman of acommittee which conducted a feasibilitystudy for a community college in 1957.Two years later, North Central Michi­gan College was established in Petoskey.Dr. Burns serves as Chairman of theBoard of Trustees.Dr. Gillette received a ProfessionalAchievement Award, which recognizesalumni whose attainments in their voca­tional fields have brought distinction tothemselves, credit to the University, andbenefits to their fellow citizens.She is retired Director of PediatricRehabilitation at the Rehabilitation In­stitute of Chicago, and has been apioneer and major contributor in the fieldof pediatric rehabilitation, especially inthe care of patients with cerebral palsy.Student HonorsMichael H. Perlin of Los Angeles hasbeen named the first recipient of theIsaac Anderson Loeb Scholarship forundergraduate research at the Universityof Chicago. Perlin, a third-year Collegestudent concentrating in biology, is con­ducting enzyme research in the mi­crobiology laboratory at Billings Hospi­tal. From this experience, he hopes tofurther develop his interest in cancer re­search.Perlin ranks second in his class of 780students. He has consistently earned aplace on the Dean's List at the Univer­sity. He has been acti ve in the HillelFoundation, the Film Society, and theDebate Club, and he has served as a vol­unteer at Billings Hospital.The Loeb Foundation was establishedon the death of Mr. Loeb in 1954. Itspurpose is to assist bright, young schol­ars at the graduate and undergraduatelevel to pursue studies in the agriculturaland biological sciences. The FoundationMichael Karbowski (left) has provided individual scholarships formore than 500 university students inscores of colleges and universities in theUnited States. This scholarship is thefirst the Loeb Foundation has endowed.MichaelKarbowski, Ph.D., a freshmanmedical student, won first place in theRoche Laboratories Award in Neurosci­ences, and third place in the MeadJohnson Award, the Excellence of Re­search Award. He received the awardsfor his research work on "The Effect ofTricyclic Antidepressants on the Turn­over of Acetylcholine in the Brain,"under the supervision of Dr. Angelos E.Halaris, Assistant Professor in the De­partments of Psychiatry and BehavioralSciences (Biopsychology).Medical Study in lithuaniaLinas A. Sidrys, who received his M.D.degree from the Pritzker School ofMedicine last June, spent the last threemonths of his senior year studying in theLithuanian Republic of the U .S.S. R.Sidrys is the son of Dr. Rimvydas Sid­rys, a Streator, Illinois ophthalmologist,and Dr. Giedra Sidrys. Like his parents,who came to the United States afterWorld War II, he speaks fluent Lithua­nian.It required a year and a half of paperwork by the Pritzker School of Medicineto obtain permission for Sidrys to do amedical rotation in the U.S.S.R., includ­ing a personal call by the Dean and VicePresident for the Medical Center to theU.S.S.R. Academy of Sciences in Mos­cow.Sidrys spent most of his three-monthstay at the University of Vilnius MedicalSchool, after a week of visits to govern­ment offices to obtain permission towork in the University's hospital. Hespent a month in internal medicine, threeweeks in cardiac surgery, two weeks ingeneral surgery, and two weeks inophthalmology.He served under Dr. Algimantas Mar­cinkevicius, a renowned cardiac sur­geon. The Vilnius cardiac service re­portedly has the best cardiac bypass re­sults in the U. S. S. R. Sidrys actuallyserved as an intern, taking part in heartoperations as the third surgeon.He spent the final week of his visit toLithuania in the brand-new 240-bedKaunas Eye Hospital, which was openedin 1976. He reports he was the firstforeigner since World War II to be per­mitted to live in Kaunas.Medical studies in Lithuania begin atabout age 18, after the equivalent of U.S.high school, and take up to six years,followed by the internship, now knownin the U.S. as a first-year residency. Medical studies there stress strict disci­pline and rote learning more than doU.S. studies, says Sidrys. U.S. studentshave much more responsibility, being in­volved in hospital admission procedures,patient care, arid preparing patients forsurgery.Dr. Sidrys began his residency train­ing in ophthalmology at the MedicalCenter in July. After three years' res­idency training, he hopes to enteracademic medicine.Beadle, Coggeshall ProfessorshipsHewson H.

She was Lecturer in Pathologyat the Institute of Ophthalmology, and isalso the author and coauthor of numer­ous research papers, including severalwith her husband. Test Predicts Fate of Comatose PatientsThe prime question in the minds of thephysicians and families of comatose pa­tients usually is: Will they survive?Dr. Jack de la Torre, a University ofChicago neurobiologist, has developed anew test that has successfully predictedthe outcome in fifteen comatose patientswho suffered severe head injuries. Thetest, which measures "evoked" nervesignals received in the so-called sensorycortex of the brain, correctly predictedfull or partial recovery in three comatosepatients and non-recovery (death) intwelve. The signals were induced in thewrists or knees.Fifteen patients both sexes aged 3 to72 who had been in a coma from 3 to 93days received the test. All had "close"head injuries in which the skull was notfractured or penetrated. All had some"brain wave" (EEG) acti vity but couldnot be aroused by external stimulation.This is the first known use of the sen­sory evoked response technique to pre­dict the outcome of coma following se­vere "close" head injury. Neurologistsand psychologists have used the tech­nique experimentally and clinically forsome years to study nerve and brain ac­tion."The combination of sensory, visual,and auditory evoked responses can nowoffer the clinician an assessment of thefunctional integrity of three diverseneural pathways," says de la Torre.The test predicts only recovery fromcoma, says de la Torre, not the extent ofpossible disability after recovery. Hesays that the technique is probably anextremely reliable index for the outcomein such patients, but warns that before afinal judgment of its usefulness is made,many more clinical case studies must beperformed.De la Torre is Associate Professor inthe University of Chicago Brain Re­search Institute and in the Departmentsof Surgery (Neurosurgery) and Psychia­try. He has also administered the test tovictims of other neurological disorders,including brain and spinal cord traumafrom accidents, multiple sclerosis andParkinsonism.New Substance Treats Drug AddictionA new heroin substitute has been foundto be superior to methadone in severalrespects for treating drug addiction. Drs.Edward C. Senay, Walter Dorus, andPierre F. Renault found that methadylacetate, a methadone analog, is as effec­tive as methadone in narcotic substitu­tion therapy.Methadyl acetate has several advan­tages over methadone:·It need only be administered threetimes a week, versus seven times a weekfor methadone.• No weekend dose is given the addictfor self-administration, as with meth­adone, making it impossible to sell it tobuy heroin.The methadone substitute has somedisadvantages:.It is more difficult to establish somepatients on maintenance doses ofmethadyl acetate. Some patients maytolerate methadone better.• Because of differences in patient tol­eration, more methadyl acetate patientsmay drop out of a maintenance program.Senay and his colleagues suggest thatsome drug abusers may have a compul­sive need for daily treatments."Methadyl acetate may be the drug ofchoice for patients with relatively goodpsychosocial adjustment," they reportedin lAMA, the Journal of the AmericanMedical Association. "A patient whogives a history of continuing heroin usebased on his need to avoid withdrawalsymptoms rather than on a psychologi­cally based need for pharmacologicalsupport and tranquilization might be bet­ter started on methadyl acetate treat­ment. Patients with evidence of a psy­chological need to use drugs compul­sively and those without employment orstable outside social supports might bebest considered for methadone mainte­nance. "Some patients, they suggest, might bestabilized on methadone and laterswitched to methadyl acetate.Dr. Senay is Professor in the Depart­ment of Psychiatry, and was Director ofthe Illinois Drug Abuse Program(lDAP), from which the patients in thestudy were recruited. Dr. Dorus is Re­search Associate (Assistant Professor)in Psychiatry and was Research Directorof IDAP. Dr. Renault was AssistantProfessor in Psychiatry and is now in theDivision of Research of the National In­stitute on Drug Abuse.Pure Erythropoietin SampleU sing urine specimens, University ofChicago scientists have obtained a puresample of erythropoietin, a hormone thatstimulates production of red blood cells.The sample of human erythropoietin iseight times more active than previouslyreported pure sheep erythropoietin sam­ples. It will make it possible to start adetailed study of erythropoietin's chemi­cal and biological properties, saysCharles K. -H. Kung, senior scientist inthe Franklin McLean Memorial Re­search Institute.If the chemical structure of ery­thropoietin can be discovered, a means Dr. Edward Senaymay be found to create synthetic ery­thropoietin to treat anemia, in whichthere is reduced ability of the blood tocarry oxygen to the tissues.When there is a need for increased redblood cells to deliver oxygen to tissue,the body normally increases the amountof circulating erythropoietin. The hor­mone then "instructs" the blood­forming tissue (mainly in the bone mar­row) to increase the production of redblood cells.Erythropoietin is formed principally inthe kidneys of humans and other mam­mals. Some victims of kidney disease areunable to produce their own body ery­thropoietin and require careful manage­ment and occasional blood transfusions.If enough pure hormone or syntheticerythropoietin were available, it mightfacilitate the treatment of anemia in kid­ney patients. At present there is notenough of the pure hormone for anytreatment purposes.How erythropoietin acts to form redblood cells from progenitor cells wouldbe useful in the study of biological differ­entiation. With erythropoietin available,this process can now be studied in pro­genitor cell cultures in the laboratory.Knowledge of differentiation, both nor­mal and abnormal, is needed to under'­stand how cancer and birth defects andother diseases may occur. Much morepure hormone will be needed before thestructure of erythropoietin is finallyestablished, says Kung.Urine from specific kinds of patients isat present the only practical source oferythropoietin. The best source for re­search purposes is the urine of aplasticanemia patients. This disease is charac­terized by a severe deficiency of red blood cells. A substantial portion of theerythropoietin in aplastic anemia pa­tients spills over into the urine and is ex­creted .Coauthors with Kung of a paper onthis research are Dr. Takaji Miyake ofKumamoto University Medical School,Japan, and Eugene Goldwasser, Pro­fessor in the Department of Biochemis­try, the McLean Institute, and theundergraduate College at the Universityof Chicago.Measuring DES Cancer RiskThe risk of vaginal or cervical cancer inyoung women associated with fetal ex­posure to DES (diethylstilbestrol, a syn­thetic estrogen) taken by the mothersduring pregnancy in the 1950s is about Iin 1,000 at most, according to Dr. ArthurL. Herbst, the Joseph Bolivar De LeeProfessor and Chairman in the Depart­ment of Obstetrics and Gynecology andChief of Staff of Chicago Lying-in Hos­pital. The odds can extend to about 1 in10,000 at the least. The difference relatesto lack of knowledge concerning howmany pregnant women took DES.Herbst theorizes that DES was one ofseveral factors that in combination mayhave caused such cancers.Herbst based the estimates on a studyof 154 DES-associated cases of suchcancers and on the estimate, based inpart on U.S. census birth statistics, thatfrom 1 to 10 percent of pregnant womenin the United States received DES in theyears 1951 to 1969.Coauthors of the paper were Dr.Philip Cole, epidemiologist at the Har­vard School of Public Health; Dr. Theo­dore Colton, statistician, DartmouthMedical School; and Dr. Stanley Rob­boy and Dr. Robert F. Scully, of theDepartment of Pathology, Harvard Uni­versity and Massachusetts GeneralHospital.Evaluating X-ray DiagnosisA World War II technique to determinethe effectiveness of radar detection isbeing studied here as a means to judgethe diagnostic effectiveness of X-ray andnuclear imaging. The technique, knownas an ROC (receiver operating charac­teristic) curve, has also been used bypsychologists in studies of auditory andvisual signals.It could be used to determine whethernew types of X-ray brain and body scan­ners (computerized axial tomography)and ultrasound imaging techniques areworth the large slims of money paid forthem by hospitals.Charles E. Metz, Associate Professorin the Department of Radiology and theFranklin· McLean Memorial Research33Institute, recently described his theoret­ical and experimental research on themedical applicability of the technique.The ROC curve, as Metz proposes touse it in judging the effectiveness ofX-ray and nuclear-imaging diagnoses,charts on a graph the relationship be­tween the frequencies of correct and in­correct positive diagnoses at various so­called "decision threshold" levels."Some diagnosticians will use a strictthreshold-they will diagnose as abnor­mal only those cases in which they areabsolutely certain that disease is pres­ent," says Metz. "They will have a highratio of correct negative decisions butwill miss some positive cases that a lesscautious radiological diagnosticianwould correctly diagnose."The ROC curve can be charted inhuman cases by comparing the actual di­agnoses made in humans to results ob­tained by surgery and pathologicalexamination.To date, Metz and his colleagues, Dr.Lee B. Lusted, Professor and FacultySecretary in Radiology, and Stuart J.Starr, a graduate student in Radiology,have only tested the ability of Universityradiologists and medical physicists to de­tect test objects in X-rays and in com­puterized radionuclide images on videoscreens. They soon hope to test themethod on cancer patients."With the increased cost of variousdiagnostic procedures, there is an in­creased need for methods to demonstratewhether the expense of new equipment isjustified by the benefits," says Metz.ROC analysis is a method of measur­ing and describing the detectability ofsignals against a background of "noise"or irrelevant image features.Each individual diagnostician has hisown "decision threshold" at which hedetermines that a significant image (or"blip" on a radar screen) is present-s-orappears to be present.The object is to chart the performanceof a variety of diagnosticians withspecific radiological or nuclear imagingequipment. Possible trade-offs in im­proved diagnosis can be revealed if thediagnostician alters his "confidencethreshold. "Surgery Repairs Ruptured SpleenThe spleen is one of the most frequentlyinjured of organs, and is normally re­moved after rupturing in a fall, auto acci­dent or fight.But total removal-splenectomy-isnot always necessary. Dr. John Bur­rington, a University of Chicago pediat­ric surgeon, has reported successful sur­gical repair-rather than removal-ofeight of ten ruptured spleens in children.34 All of the children recovered withoutsubsequent infection or illness. In two ofthe ten cases, the patient's spleens wereremoved because of associated injury tothe pancreas.It is possible for most adults to livewithout spleens, but infants and youngchildren are highly susceptible to infec­tion after splenectomy. The juvenilemortality is much higher. It is nowthought that an intact spleen helps pro­duce such defenses against disease aswhite blood cells and opsonins (anti­bodies that render bacteria and damagedred blood cells susceptible to ingestionand digestion by white blood cells knownas phagocytes).Of the ten children upon whom Bur­rington operated, five were victims ofauto accidents, three were injured infalls, one was injured in a sledding acci­dent, and one was a suspected victim ofchild abuse.Damaged and dead tissue resultingfrom cracks and tears was removed fromthe spleens of six of the patients, and thespleen sutured. Torn-away material wasremoved from the spleens in two victimsand the wound sutured. In six of the tenpatients, the spleen was still bleedingwhen exposed.Burrington favors careful abdominalexploration to observe the extent ofdamage to the spleen and the possibilityof associated injuries. The surgical tech­niques widely used to preserve damagedliver and kidney tissue are equally appli­cable to spleen tissue, he says.Burrington is Professor and Head ofthe Section of Pediatric Surgery in theDepartment of Surgery and Wyler Chil­dren's Hospital.Brain Cell Maturation FactorDr. Ramon Lim, a physician andbiochemist in the University of ChicagoBrain Research Institute, has reporteddiscovery of a protein that promotesmaturation in a type of embryonic braincell known as glial cells. He has ob­served its effect on rat brain cells underthe microscope. A similar maturationfactor presumably exists in humans.The discovery presents several sig­nificant aspects:.Mental retardation: Retardation isdue to inadequate development of braincells; some type of the disease is possiblydue to a lack of glia maturation factor. Ifso, the patient might benefit from ad­ministration of the factor..Brain tumors: The majority of braintumors are caused by the uncontrolledgrowth of the glial cells resulting fromreversion of the mature glia to the un­differentiated primitive predecessorcells. Lim infers that lack of the factor This patient room in the new eight-bed acuteintensive care section of the University's BumCenter is equipped with heat lamps and a built­in monitoring console. Color television andvibrantly-colored walls combat sensory de­privation during long periods of hospitalization.An open house for the new Center was held onJune 6.may permit normal glial cells to revert toa more primitive state, forming glial-typecancer cells. "Glia maturation factormight enhance the maturation of theseprimitive-type cancer cells, thus slowingdown or arresting tumor growth," hesays..Head injury: In cases of brain dam­age from head injury, there is usually anexcessive growth of differentiated glialcells as part of the repair mechanism ofbrain tissue, a condition known as gliosis(formation of glial scar). It is possiblethat when neurons are injured they re­lease the glia maturation factor, whichtriggers gliosis. Gliosis can lead to long­term effects on the brain, such asepilepsy. In this case, unlike the case ofbrain tumors, says Lim, the appropriateremedy would be to inhibit the develop­ment of glial cells. "We hope to reducethe extent of gliosis by administering anantiserum against glia maturation factorwhich we hope to develop," he says.Lim cautioned that he and his col­leagues have not conducted any tests onhumans, and" any use for humans at thisstage is only speculative."Lim is Associate Professor in the De­partments of Surgery (Neurosurgery)and Biochemistry. His colleagues in thisresearch are David E. Turriff andShuang S. Troy, Research AssociatesDr. Ramon Lim(Assistant Professors) in the Departmentof Surgery (Neurosurgery).The glia maturation factor that theydiscovered is a large molecule present inthe adult brain but found only in smallquantity in the embryonic brain andbrain tumor."Although a similar factor for neuronshas been detected before," says Lim,"this is the first instance where a proteinthat can stimulate the glial cells to differ­entiate has been found. We believe thatthe glia maturation factor exerts' its effectby promoting the glial cells to communi­cate with one another, a process impor­tant in cell differentiation. The loss ofthis factor may result in the lack of com­munication between the glial cells, whichin tum may lead to the underdevelop­ment of the brain. Conversely, the lackof communication may lead to the un­controlled growth of the undifferentiatedcells-the formation of tumors. It isworth noting that almost all tumors aris­ing from the brain come from the glialcells. "In MemoriamRichard W. Reilly, 1926-1977Dr. Richard W.
