Nephron function in acute glycerol-induced renal insufficiency in rabbits.

The effect of acute experimentally induced renal failure after intramuscular injection of glycerol on serum and urine GGTP, LAP and AP activities was studied in 30 rabbits. High doses of glycerol caused shock, myolysis and hemolysis, leading to acute renal insufficiency. Serum urea and creatinine levels significantly increased, there was proteinuria, and significant decrease in 24-hr diuresis, glomerular filtration, and urinary urea excretion. The changes in LAP and AP activities were significant, and in GGTP-nonsignificant. In the urine GGTP and LAP increased significantly, and AP nonsignificantly. Urinary excretion of AP increased significantly, and GGTP and LAP nonsignificantly. The highest activity and urinary excretion of GGTP and LAP were observed on the 2nd day, and of AP--on the 5th day of renal failure.
