Electrolyte composition changes of chronically K-depleted rats after K loading.

The responses of whole body, skeletal muscle, and plasma to oral K loading were studied in K-depleted male rats. Potassium depletion was induced by feeding the rats a K-deficient diet for 4 wk and injecting deoxycorticosterone acetate during the first week. After 4 wk, the rats were growth retarded and hypokalemic (1.
