title: [Effect of the antioxidant dibunol on the function of the adrenal cortex, the thyroid and the adenohypophysis in adult and old rats].
abstract: The effect of a single antioxidant (dibunol-D) injection (100 mg/kg body weight) on the functional activity of adrenal cortex (AC), thyroid gland (TG) and tropic hormone production by adenohypophysis (AH) has been studied in old and adult rats. For 48 hours following D administration two-phase changes in adrenocorticotropic function of AH and steroidogenesis were detected in the AC: activation during the first hours was followed by suppression 24 hours later, and recovery 48 hours later. Thyrotropic AH function and thyroidogenesis were found to be decreased during the first hours of D effect. Thyroidogenesis recovery by the end of the first day was delayed as compared to the recovery of AH thyrotropic function. It is suggested that the mechanisms of D action are based on its effects mediated by changes in the functional activity of endocrine glands and associated with resetting of endocrine regulation of body functions.
