[Renal mechanisms of protective potassium effect in essential hypertension].

In experiments on nonlinear rats, the renal functions were investigated at aqueous diuresis induced by intragastric administration of sodium potassium, potassium hydrocarbonate (20 mM/kg), and potassium succinate (10 mM/kg). We have found that the load by potassium raised glomerular filtration rate and sharply increased excretion of not only K+ but also Na+ and Cl- with urine, that led to hyponatremia and hypochloremia following hyperkalemia. In...
