Abstract

The dynamics of fluctuations of capillary blood flow in the cortex of rat kidneys under conditions of transient occlusion of renal arteries and veins or simultaneous occlusion of afferent and efferent vessels was studied by laser Doppler flowmetry. The initial variability of blood flow in the right kidney was higher than in the left kidney. The most pronounced changes in the right kidney were observed during occlusion and subsequent recirculation. In the left kidney, the most pronounced changes were found during occlusion and after arterial occlusion. Spectral analysis gave similar results. The recovery of renal blood flow after transient venous occlusion took longer time than after arterial occlusion (especially in the right kidney).
