[Effect of interstitial factors on parameters regulating fluid transport through the walls of the mesenteric vessels of the cat].

With the aid of microocclusion technique, hydraulic conductivity and effective pressure were studied in different blood vessels of capillary type in the cat mesenterium. The fluid permeability of the microvessel walls depended on their segmentary type, vector of transmural flux and protein content of surrounding tissue. The greatest value of the hydraulic conductivity was found in the postcapillary venules. The anisotrophic distribution of fluid in the interstitial spece seems to depend on topography of the microvessels with different transport characteristics.
