[Renal blood flow as a factor in the realization of trophic influences during compensatory hypertrophy under denervation].

In the Wistar rats, the effect of nervous decentralization of a single kidney on the changes of local blood flow in the cortex and medulla, was studied. Phasic changes of the intraorganic [correction of interorgan] hemodynamics involving a cortical perfusion increase during 15 days followed by a progressive decrease of the local blood flow, were recorded. The redistribution in the kidney blood flow involved a decrease of the tissue blood flow in the cortex within 30 days along with a rise in the local medullary blood flow. The cortical blood flow decrease was due to a changed reactivity of the denervated kidney's arterioles and lesion of the tubulo-interstitium in the cortex.
