Abstract: | The effects of propranolol (l mg/kg/H infused in the renal artery) on the diuretic action of furosemide (20 mg/kg i.v.) have been studied in pentobarbital anesthetized dogs. We obtained the 3 following results : the urine remained isotonic to the plasma during the 6 hours following the furosemide injection ; the urinary output of sodium and water, measured during 6 hours after furosemide injection, was increased ; the renin hypersecretion was inhibited. |
