[Responses of the mesenteric microcirculatory bed of rats with experimental renal hypertension to histamine and adrenaline].
Reactions of the blood flow and of the diameter of mesentery arterioles were studied in vivo after the application of histamine (100--500 gamma) and adrenaline (1--10 gamma) in normal rats and in the animals with renal hypertension. A decrease of sensitivity of the microvessels, 10--30 mu in diameter, to the action of these substances was shown in the animals with hypertension.
