[Compensatory-adaptive responses of the microcirculatory bed of rat mesentery in hypoxia]
Abstract
Television microscopy and stroboscopic determination of the blood flow speed showed that linear and volumetric speed of the blood flow in arterioles with gauge 40--20 mcm and venules with gauge 40--50 mcm diminished during repeated action of hypoxia and constrictory reaction. In capillaries and postcapillary venules with gauge 11--39 mcm, there was a dilatation with an original increase and subsequent decrease of the blood flow speed.
