[Participation of vasopressin and adrenal gland adrenaline in the mechanism of reflex coronary vasoconstriction].

In 17 acute experiments on sympatho- and vagotomized cats under chloralose anesthesia in conditions of stabilised blood pressure following bilateral common carotid arteries occlusion, similar coronaroconstriction occurred before and after adrenalectomy. The increase of latency and maximum of reaction were obvious in adrenalectomized cats as well as clear correlation between the coronaroconstriction and elective activation of HHNS as manifested in the increase of synthesis, transport, and release of vasopressin into blood flow. The data suggest participation of both endogenous vasopressin and epinephrine of adrenal glands in coronaroconstriction bollowing carotid occlusion.
