Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...

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 f...

objective(s): snake venoms contain complex mixture of proteins with biological activities. some of these proteins affect blood coagulation and platelet function in different ways. snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. in the present study, purification of anticoagulation factor from veno...

Viper’s venom is a source of biopharmaceutical compounds, hence the need to assess the effect of this animal extract on human blood. Here, we studied the blood coagulation disorders and hemolytic activities of the venom of M. bornmulleri viper. The pro-coagulant and anticoagulant effects are analyzed with venom concentrations ranging from 0.4 to 0.0031 mg/mL. Thus, the PT is way above the norma...

The biological activity of a Habu (Trimeresurus flavoiridis) venom fraction with drug-metabolizing enzyme inhibitory action was studied. The venom fraction, which was isolated through Sephadex G-100 gel filtration and cation exchange chromatography on Amberlite CG50, caused an increase of vascular permeability and hemorrhage, but these actions were lost after heating at 70 degrees C for 5 min. ...
