title: Lysosomal membrane stabilization by alpha-tocopherol against the damaging action of Vipera russelli venom phospholipase A2.
abstract: This investigation shows the membrane stabilizing effect of alpha-tocopherol against the damaging action of viper venom phospholipase A2 (PLA2). Liver lysosomal membranes from rats fed 100 mg and 200 mg alpha-tocopherol acetate per kilogram of diet were more resistant to damage by viper venom PLA2 compared with vitamin E-deficient rats. The membrane stabilizing effect of vitamin E is proposed to be due to the formation of a complex with the phospholipid hydrolysis products of the membrane.
