[Participation of hypothalamic adrenergic and cholinergic systems in the regulation of pituitary adrenocorticotropic function].
Experiments were conducted on male rats; a study was made of the activity of pituitary-adrenal cortex system under conditions of electrolyte destruction of various hypothalamic areas. Pharmacological analysis pointed to the irregular distribution in the hypothalamus of the cholinergic and adrenergic systems controlling the secretion of ACTH-glucocorticoids. As suggested, the cholinergic systems are situated in the mammillary region, alpha-adrenergic ones--in the anterior or the posterior regions of the hypothalamus, and beta-adrenergic receptors--in the ventromedial nuclei of the hypothalamus. The latter possibly play an inhibitory role.
