Abstract
In acute experiments on cats, under conditions of autoperfusion of the small intestine vessels, acute hypoxic hypoxia led to a ahort-term increase of the precapillary resistance and a stable decrease of the postcapillary one, to a decrease of capillary hydrostatic pressure and absorption of fluid from the interstitial space into the blood with an increase of the axchange surface. The mechanisms of above vascular and filtration-absorbent changes in the intestine during hypoxia, are discussed.
摘要
在对猫进行的急性实验中，在小肠血管自身灌注的条件下，急性低氧性缺氧导致毛细血管前阻力短期增加，毛细血管后阻力持续下降，毛细血管流体静压降低，液体从间质间隙吸收进入血液，交换面积增加。文中讨论了缺氧时肠道上述血管和滤过吸收变化的机制。
