V. russelli venom induces predominantly neurotoxic, mytotoxic necrotic, and hemorrhagic symptoms in exptl. animals and has several hydrolytic enzyme activities. In this study, V. russelli venom is characterized both as a PLA2 and as a toxin. Anti PL-V Ig (antibodies to a toxic phospholipase A2 VRV PL-V of V. russelli venom) nullifies the toxicity of whole V. russelli venom to a great extent. The neurotoxic symptoms vanish completely in the presence of anti PL-V Ig. The cross reacting components of whole V. russelli venom were removed by precipitating them from whole venom by the addition of anti PL-V Ig. The non-cross reacting components present in the supernatant were checked for toxicity. There was a significant reduction in toxicity. The LD50 value of the supernatant had increased from 4.1 mg/kg body weight to 11.7 mg/kg body weight, and it showed about 34% of the total venom phospholipase A2 activity. It had edema forming, hemorrhagic, and hemolytic activity but failed to induce neurotoxic, anticoagulant, and myotoxic effects.
