[The effect of aldosterone on the second messenger systems in the rat kidney]
The effect of aldosterone on the cAMP level, the state of inositol-phosphate pool and the intracellular free Ca2+ activity in the rat kidney, were studied. The cAMP level in the kidney cortex homogenate was not changed after i.p. injection of aldosterone. Reliable changes in the content of inositol-phosphates in the kidney cell suspension was not revealed after aldosterone treatment. A short-term
