[The role of adrenergic receptors in the realization of hypothalamic effects on the motor function of the digestive tract in hypophysectomized dogs].
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 inhibitory effects of the stomach while stimulating hypothalamic structures during work of the digestive tract. The blockade of beta-adrenoreceptors by obsidan induces weakening of excitatory responses of the digestive tract and intensification of inhibitory ones while stimulating hypothalamic structures in hypophysectomized dogs.
