[Local cortical and medullary blood flows to the single kidney in chemical sympathectomy].
Topological shifts of intracortical and intramedullary blood flow were studied with the hydrogen clearance technique in the single kidney of Wistar rats. A hyperperfusion of the cortex due to contralateral nephrectomy and vasodilating effect of sympatholytic agent, was found during first 24 hours. Cortical blood flow decreased and medullary one increased within 7 days, which was due to compensatory shifts in the kidney necessary for the adaptation of the kidney to the tissue deficit of adrenergic transmitter, and for the maintenance of the water-salt homeostasis in conditions of a systemic peripheral sympathectomy .
