[Changes in the local blood flows of the single kidney with partial impairment of the autonomic innervation].

The changes of cortical and intramedullary blood flow of the remaining after nephrectomy kidney under the condition of guanethidine sympathectomy and continuous pharmacological blockade of parasympathetic mediation by atropine were studied in chronic experiments on Wistar line rats in dynamics at 4, 7, 15, 30, 60, 90 and 120 days. Decrease in cortical and increase of intramedullary peritubular blood flow were noted in both experimental series, that is both blockade of sympathetic and parasympathetic nerves after 15 days. The conclusion was made that blood flow redistribution is a universal mechanisms of single kidney adaptation to its neurogenic impairments.
