RDG006004 The present program of the Institute encompasses three main areas: clinical support, disease prevention, and adaptation of men to new weapons systems. The major efforts in clinical support involve experimental surgery, experimental medicine, and experimental dentistry, all involving the development of new techniques, applications, and concepts for the treatment of naval casualties. Experimental surgery is focused on problems of vascular physiology of major importance in military medicine. Work in isolated organ perfusion looks towards the development of successful organ transplantation, which has a direct bearing on treatment of combat injuries where there has been irreparable damage to vital organs. Although these studies involve animals, the same care is taken as would be in an operation on a human being; identical aseptic techniques, careful preoperative and post-operative care, and anesthesia are used. During the kidney transplant pictured here, a special computer records cardiac output, and other vital functions are recorded on a polygraph.
