CHARACTERIZATION OF AN ANTICOAGULANT AGENT IN THE VENOM OF IRANIAN COBRA (NAJA NAJA OXIANA).
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 filtrat...
متن کاملProteomic characterization of the thermostable toxins from Naja naja venom
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...
متن کاملCharacterization and physical properties of the major form of phospholipase A2 from cobra venom (Naja naja naja) that has a molecular weight of 11,000.
The major form of phospholipase A2 from cobra venom (Naja naja naja) was prepared in 30% yield and was homogeneous on polyacrylamide gel electrophoresis with and without sodium dodecyl sulfate and on Sephadex G-100 chromatography. The monomer molecular weight is about 11,000 according to sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Ultracentrifugation and molecular sieve technique...
متن کاملThe Protective Effects of Cobra Venom from Naja naja atra on Acute and Chronic Nephropathy
This study investigated the effects of Naja naja atra venom (NNAV) on acute and chronic nephropathy in rats. Rats received 6 mg/kg adriamycin (ADR) once to evoke the chronic nephropathy or 8 ml/kg 50% v/v glycerol to produce acute renal failure (ARF). The NNAV was given orally once a day starting five days prior to ADR or glycerol injection and continued to the end of experiments. The animals w...
