The histological and biochemical changes in adrenal function has been studied in 50 male cats with circulatory failure. The adrenal glands were examined by morphometric, histochemical and histoenzymological methods after a preliminarily study of the histoenzymological profile of the adrenal glands in intact animals. Five hours after hypotension induced by intravenous injection of trimethaphan and 5 hours after a single massive bleeding, a decrease in adrenal function was observed. Adrenal insufficiency especially of the glucocorticoid release in the course of acute circulatory failure can be considered as a peculiar adaptation of the organism to preserve its life. The demonstrated decrease of adrenal function in the first hours of hypoxia may help in planning hormonal therapy under suitable conditions.
