DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE PUBLIC HEALTH SERVICE HEALTH SERVICES AND MENTAL HEALTH ADMINISTRATION November 13, 1978 NATIONAL INSTITUTE OF MENTAL HEALTH DIVISION OF SPECIAL MENTAL HEALTH RESEARCH, IR SAINT ELIZABETHS HOSPITAL - WAW BUILDING Our Reference: SMRC WASHINGTON, D.C. 20032 , AREA CODE 202 TEL: B74~7572 Dr. Joshua Lederberg gocreteiten Gi Office of the President The Rockefeller University 1230 York Avenue New York, New York 10021 Dear Dr. Lederberg: In addition to whatever help I can be to you with your clinical research planning, we might discuss the enclosed two papers when we meet on December 1. The first paper describes in abstract form how two vulner- ability factors might come together to produce a disorder such as schizo- phrenia. In this case, low monoamine oxidase activity and being a heterozygote for PKU impact on the formation and metabolism of phenyl- ethylamine. The second paper deals with the issue of partial brain grafts which may ultimately be of use in treating neurologic disorders. It not only raises many scientific issues but ethical ones as well. Best wishes and, Sincerely yours, Richard J. Wyatt, M.D. Chief, Laboratory of Clinical Psychopharmacology Enclosure
