title: [Mechanisms of action of beta-endorphin on the secretion of hypophyseal hormones].
abstract: The purpose of the study was to investigate some mechanisms of the effect of beta-endorphin on somatotropic and lactotropic function of the hypophysis, adrenal activity and the content of catecholamines in the cerebral tissues. Activation of the hypophyseoadrenal system, lactotropic and somatotropic functions 5-20 min after beta-endorphin administration was established in experiments on male rats. At the same time a decrease in the content of catecholamines in the hypothalamus, cerebral cortex was observed. It was most significant for dopamine participating in the regulation of ACTH, prolactin and somatotropin secretion.
