Pharmacokinetics of the venom of Bothrops erythromelas labeled with 131I in mice.

Bothrops erythromelas venom (BeV) has been responsible for many snake accidents in Brazil. We investigated the plasmatic pharmacokinetic of BeV labeled with (131)I in the absence and the presence of anti-Bothrops serum (BAS). A higher percentage of BeV plasmatic radioactivity and longer elimination were found in the presence of BAS.

BE-I-PLA2, a novel acidic phospholipase A2 from Bothrops erythromelas venom: isolation, cloning and characterization as potent anti-platelet and inductor of prostaglandin I2 release by endothelial cells.

A novel acidic Asp49 phospholipase A(2) was isolated from Bothrops erythromelas (jararaca malha-de-cascavel) snake venom by four chromatographic steps. BE-I-PLA2 present a molecular weight of 13,649.57 Da as estimated by mass spectrometry.
