[Action of furosemide in experimental acute renal failure (author's transl)]

The action of furosemide was studied in glycerol-induced acute renal failure of rats. Acute renal failure was induced by an intramuscular injection of 50% glycerol (10 ml/kg). A marked increase in plasma urea concentration was found after the glycerol injection. Urea concentration increased to a maximal value of 339 +/- 67 mg/100 ml at the third day after glycerol application. 36% of the animals died within the first 4 days after glycerol. Furosemide (20 mg/kg) was injected intraperitoneally daily and for the first time 24 h after injection of glycerol Mortality and azotemia of acute renal failure was not improved by this drug.
