Abstract

Rats with hereditary hypothalamic diabetes insipidus (so-called DI rats) have elevated plasma renin levels. Although the mechanism responsible for this condition has not be elucidated, it seems reasonable to postulate that the absence of ADH and/or the hypokalemia previously reported in these rats might contribute to the elevation of plasma renin concentration (PRC). Evidence in favor of this hypothesis emerges from studies in which both ADH and potassium have been shown to inhibit renin release. In an attempt to examine the relative roles of ADH and potassium in the regulation of renin secretion, PRC was measured in DI rats maintained on a potassium-free, normal potassium, or high potassium diet in the presence and absence of ADH treatment.
