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(More)
Chronic experiments in dogs showed that, after i.v. injection of oxytocin, the latency of activation of gastrointestinal motility by the stimulation of median hypothalamic structures was increased and inhibitory effects of posterior hypothalamic structures on the contractile activity of the digestive tract were intensified. The data obtained suggests that(More)
Chronic experiments on hypophysectomized dogs with gastric and small intestinal fistulas as well as with hypothalamus-implanted electrodes have shown that blockade of alfa-adrenoreceptors by phentolamine increases the number of the excitatory motility responses while stimulating hypothalamic structures during rest of the gastrointestinal tract and decreases(More)
