Abstract

1. The renal response to aldosterone, measured by urinary sodium and potassium excretion, was determined in adrenalectomized rats that had been previously fed either a high potassium diet or a control diet. High K+ rats showed an enhanced response to aldosterone at all doses tested. 2. The induction of this enhanced response to aldosterone could be suppressed by a high sodium intake. It may also require the presence of the adrenal glands during the induction period, although interpretation of adrenalectomy experiments in the present study was made difficult by the effect of maintenance DOC therapy on the renal response to aldosterone. 3. The enhanced response could not be induced by a low so..
