[Effects of aldosterone and vasopressin on the intracellular Ca2+ activity in the cortical collecting tubules of rat kidneys]
Effects of aldosterone and vasopressin on the intracellular Ca2+ activity in the isolated cortical collecting tubules were studied. Both aldosterone and vasopressin were shown to evoke a transient increase in intracellular Ca2+, the response amplitude being not reduced in the presence of the other hormones. As vasopressin via its membrane receptors, aldosterone is suggested to activate the system
