title: [The effect of aldosterone on the second messenger systems in the rat kidney].
abstract: 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 enhancement of the intracellular Ca2+ activity in the isolated distal convoluted and cortical collecting tubules under the influence of aldosterone, was revealed. The participation of the second messenger systems in the realisation of aldosterone effects in kidney and the role of Ca2+ in the mechanism of aldosterone action, are discussed.
