[Vasomotor responses of the small intestine during acute overheating of the body].
In anesthetized cats under conditions of acute overheating, resistance to the blood flow increased in arteries of the small intestine whereas compliance of the postcapillary vascular bed reduced in respective linear dependence. The correlation-regression analysis indicated a close linear dependence between changes in arterial vessels of the small intestine to heating and their responses to the pressor carotid sinus reflex. The mechanism responsible for splanchnic vasoconstriction under conditions of acute overheating of the organism seems to involve increased efferent impulses activity mediated by the adrenoreactive structures.
