The vulnerable Chinese cobra (Naja atra) ranges from southeastern China south of the Yangtze River to northern Vietnam and Laos. Large mountain ranges and water bodies may influence the pattern of genetic diversity of this species. We sequenced the mitochondrial DNA control region (1029 bp) using 285 individuals collected from 23 localities across the species' range and obtained 18 sequences un...

AIM OF THE STUDY Evaluations of the anti-snake venom efficacy of Mimosa pudica tannin isolate (MPT) obtained from root of the plant. MATERIALS AND METHOD MPT was investigated in vitro and in vivo for its efficacy against the venom of Naja kaouthia snake. RESULTS In vitro: (1) mice injected i.p. with MPT pre-incubated with Naja kaouthia venom at concentrations as low as 0.625 mg/ml showed 10...

Naja naja snake venom presents abundant thermostable peptides. Many of them possess useful pharmacological activity that may be employed for drug development. For the proteomic characterization of such toxins, in the present study, Naja naja venom solution was heated up to 100°C for 10, 30, 60, 120, 180 and 300 minutes and protein fractions of non-heated and heated venom were analyzed by twodim...

The activity of phospholipase A on phosphatidyl choline and phosphatidal choline spread as monolayers on phosphate buffers containing snake venom (Crotalus atrox or Naja naja) was studied by measuring the fall of surface potential as a function of time, pH, film pressure, temperature, and concentrations of phosphate and venom. At 25OC, pH 7.0, and 0.2 fig of venom per ml, optimal activity was o...

Recent recognition about snake bite envenomation on June, 2017 as neglected tropical disease under category-A by World Health Organization advocated again its undeniable importance. Present circumstances reasoned to work on a neglected subspecies of Naja naja, i.e., Naja naja karachiensis (N. n. karachensis) has been documented for frequent deaths in Pakistan. In this study median lethal toxic ...
