[The role of histamine in regulation of spontaneous electrical activity of the rat ureter and bordering to bladder area].

The nature of the influence of histamine on the slow wave and spike spontaneous activity of both perirenal and peribladder bordering areas of the bladder zone has been studied. It is shown that under these conditions of activated renal section of the organ, in the distal part, the decrease in frequency of the slow waves occurred. The histamine effect also contributes to improvement of the conduction of the excitation wave propagating to the bladder, which destroys the coordination of spike activity of the latter with slow waves of ureteral bordering zone.
