| Abstract: | The cytotoxic effect of venoms from six crotalinae Peruvian snakes (Bothrops atrox; B. brazili; B. pictus; B. barnetti; Lachesis m. muta y Crotalus durissus terrificus) was studied in an in vitro system of BALB/c 3T3 fibroblasts grown in Dulbecco modified minimal essential medium at 37 degrees C in a humidified atmosphere of 5% CO2-95% air. The viability of the cells was evaluated 24 hours after the treatment with the different venoms, using the method of exclusion of trypan blue. The six venoms produced cytotoxic effects at 24 hours on the 3T3 fibroblasts. The venom from B. atrox was the most potent (DE50 = 162 ng/ml) and that from B. barnetti the least (DE50 = 7182 ng/ml). |
