Abstract
Biological properties of Russell's viper (Daboia russelii siamensis) venoms collected from 5 localities (Htantabin, Kungyankone, Hmawbi, Hlegu and Indaing) of Yangon division were studied according to WHO recommended methods. Htantabin venom is the most potent among others. Both adult and young viper venoms of Htantabin possess potent lethality, capillary permeability increasing activity; necrotic and defibrinogenating activities inthe former and haemorrhagic in the latter. In contrast, adult venoms of Kungyankone has potent haemorrhagic and coagulant activities and the young has potent necortic and defibrinogenating activities. Such variation in venom properties may be responsible for variation in clinical pictures of Russell's viper bite cases seen within the same division and variable performance of antivenom.
