[The action of noradrenaline, vasopressin and deoxycorticosterone acetate on the activity of the Na+,K+ pump in the veins and arteries of different vascular regions].
Noradrenaline and vasopressin were shown to stimulate the Na+/K(+)-pump activity both in veins and in arteries, whereas desoxycorticosteronacetate did not increase it in pulmonary and mesenteric vessels and even depressed it in the mesenteric vein. There is different potentiation exerted by noradrenaline and vasopressin upon the Na+/K(+)-pump activity in veins and in arteries. The data obtained suggest the regional heterogeneity in the Na+/K(+)-pump activity in neurohormone activated blood vessels.
