[The interaction of the medical researcher with other scientists]

A brief review of nonmedical scientists contributions to medicine is done. Information on morphology, physiology, biochemistry obtained with high technology has been increasingly used in the clinical work. Therefore broad knowledge and skills have turned to be necessary, though almost impossible to get by one person alone. The answer to this problem is the interdisciplinary team work on basic problems: diagnosis, prognosis, treatment, epidemiology, public health, management of health services, etc. By these work the physician must use models and "black boxes". Both concepts are reviewed. Some proposals to improve the relationships among physicians and other scientist are made.
