Inhibition of renin secretion from incubations of rat kidney cortex by angiotensin II (AII), ouabain and K+ depletion, depended on the presence of external Ca2+. AII inhibition of isoprenaline-stimulated renin secretion was only partially dependent on external Ca2+. Ouabain and K+ depletion inhibited isoprenaline-stimulated renin release but only in the presence of external Ca2+. Since, in Ca2+-free medium, isoprenaline stimulated renin release when the Na+/K+-ATPase was blocked, isoprenaline probably does not act through the Na+/K+-ATPase. Lanthanum blocked the stimulation of renin release by isoprenaline. Ethylenediamine tetra-acetic acid (EDTA) and ethyleneglycol-bis-(beta-amino-ethyl eth..
