The topic “Ethics in Research and Surgical Practice” appears most appropriate for the 1997 Claude H. Organ, Jr. Honorary Sandoz Nutrition Lecture. With the increasing numbers of ethical problems facing clinicians today, greater emphasis on ethics is demanded. This lecture focuses primarily on the clinical applications of basic science and ethics certainly plays a major role in this regard. Ethical principles espoused by the American College of Surgeons and the American Medical Association will be emphasized. Further, the results of the deliberations of the Advisory Committee on Human Radiation experiments wilt be discussed. Certainly, the Tuskegee experiment debacle will be mentioned. Ethics remains important if we are to give our patients the best care. We must always keep in the vanguard of our thinking that the welfare of our patients comes first. High ethical principles emphasize our obligations and responsibilities to our patients.
