Abstract
Decreased muscle potassium and increased sodium in rats made magnesium deficient suggested the possibility of increased aldosterone secretion. Muscle and plasma electrolytes and secretion of aldosterone and corticosterone in magnesium-deficient rats were compared with the same values in pair-fed controls. Aldosterone secretion by the magnesium-depleted animals was increased, while corticosterone secretion was decreased. Altered steroid secretion adequately explains the altered sodium and potassium metabolism. (Endocrinology80: 969, 1967)
