CHARACTERIZATION OF AN ANTICOAGULANT AGENT IN THE VENOM OF IRANIAN COBRA (NAJA NAJA OXIANA).
Authors
Abstract:
Snake venoms contain a rich variety of factors which affect blood coagulation. There have been few reports on the anticoagulant activity of the venom of different cobras, but no such observations have been made on the Iranian cobra, although a procoagulant factor has been described. In this study an anticoagulant factor has been purified from the venom of Naja naja oxiana using gel filtration followed by isopycnic ultracentrifugation with 30% KBr. The factor was a glycoprotein with a molecular weight of 45.36 kDa and increased plasma recalcification time by 224 sec which was 7.7 times greater than the activity of crude venom.

The myocardial effect of snake venoms is considered as one of the most common pathogenesis in many cases of snake envenomation. This study was under taken to investigate the effects of snake (Naja naja oxiana) venom on cardiac function in experimental animals. The blood samples from all the rabbits were collected before venom injection and then 140 µg/kg venom of snake (Naja naja oxiana) was in...

Abstract Cancer is the leading cause of death worldwide. Current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. Present study investigated cytotoxic effects and mode of cell death induced by the Caspian cobra venom in some human cancer cell lines. Cytotoxic effects of snake venom toxin...

Cobra venom cytotoxins are basic three-fingered, amphipathic, non-enzymatic proteins that constitute a major fraction of cobra venom. While cytotoxins cause mitochondrial dysfunction in different cell types, the mechanisms by which cytotoxins bind to mitochondria remain unknown. We analyzed the abilities of CTI and CTII, S-type and P-type cytotoxins from Naja naja oxiana respectively, to associ...
