Abstract
Based on degradation of sphingomyelin/cholesterol liposomes containing entrapped horseradish peroxidase, we evaluated the Sphingomyelinase-D (SMase-D) activity of scorpion, spider and snake venoms by monitoring spectrophotometrically the product of oxidation of HRP released. The results indicate that Loxosceles crude venoms (Loxosceles intermedia, Loxosceles laeta, Loxosceles gaucho and Loxosceles similis) displayed SMase-D activity in a concentration-dependent manner. Furthermore, this activity was blocked by the anti-loxoscelic antivenom. However, Tityus serrulatus scorpion venom, Phoneutria nigriventer spider venom and Bothrops jararaca, Crotalus durissus, Lachesis muta and Micrurus frontalis snake venoms did not show measurable SMase-D activity.
