| Popis: | Many studies have reported the occurrence of lethal acute renal failure after snakebites. The aim of the present investigation was to determine alterations in renal function produced by Crotalus durissus terrificus venom and crotoxin as well as the histological alterations induced by these venoms. Isolated kidneys from Wistar rats weighing 240 to 280 g were perfused with Krebs-Henseleit solution containing 6 g% of previously dialyzed bovine serum albumin. The effects of Crotalus durissus terrificus venom and crotoxin were studied on glomerular filtration rate (GFR), urinary flow (UF), perfusion pressure (PP) and percentage sodium tubular transport (%TNa+). The infusion of Crotalus durissus terrificus venom (10 µg/ml) and crotoxin (10 µg/ml) increased GFR (control80 = 0.78 ± 0.07, venom80 = 1.1 ± 0.07, crotoxin80 = 2.0 ± 0.05 ml g-1 min-1, P |
