Influence of Potassium Deprivation and Adrenalectomy on Potassium Concentration of the Myocardium

Abstract
Adrenalectomy induced a rise of plasma K in rats fed K-deficient diet as well as those fed stock ration. Adrenalectomy induced a rise of K in skeletal muscles of rats previously depleted of K. However, no rise of K was found in skeletal muscles of adrenalectomized rats which were not preoperatively depleted of this cation. The adrenal-insufficient state was not associated with a rise of K in the myocardium in either group of rats during the 14-day period of study.
