The polyparametric description of adaptation syndromes in students using a uniform set of parameters of cardiovascular system and their relationships is presented. An analog of adrenocorticotropic hormone (ACTH4-10) is shown to exert varying effects on the development of different adaptation syndromes. Adaptation syndromes characterized by moderately active physiological processes (as judged by EGG, rheovasogram, respiration rate) and lowered vascular tonus were associated with marked improvement of the health status.
