[Interaction of ionic membrane mechanisms in the regulation of slow electrical activity of the smooth muscle cells of the ureter].
The effects of Na-free medium, Na-K pump inhibitors, ATP and Ca++ ion antagonists in calcium channels (verapamil, Mn++) on the slow-wave spontaneous activity of the ureter pace-maker zone were studied under conditions of i. a. perfusion of kidney. A reduction of membrane potential oscillations was observed.
