title: [Role of the hypothalamo-hypophyseal neurosecretory system in the accomplishment of the antistress effect of substance P].
abstract: Light and electron microscopy and spectrophotometry were employed in study of the morphofunctional condition of the hypothalamo-hypophyseal neurosecretory system (HHNS) of intact rats after exposure to stress in injection of substance P. Injection of 12.5 mcg/100g of substance P decelerates the outflow of the neurosecretory substance in intact animals and inhibits the processes of biosynthesis in the neurocytes of the hypothalamic supraoptic nucleus. Injection of substance P prior to exposure of the organism to the stress effects leads to diminution of the HHNS response of them and prevents the development of dystrophic changes in the gastric mucosa.
