[Role of tissue depots and the kaliuretic effect of aldosterone in potassium homeostasis].

The concentration of potassium in the blood serum and in the skeletal muscle increased in consequence of daily administration of 1.25% KCl solution during 4 days in rats and frogs. The concentration of potassium in frog m. soleus increased by over 50%. DOCA administration together with KCl solution increased the excretion of potassium by kidney. Olivomycin and puromycin inhibited the sodium reabsorption and did not effect the potassium secretion by rat kidney.
