چکیده

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% inhibition). attempts to measure the antiplatelet aggregation activity of crude echis carinatus venom and its fractions were not successful due to the protein coagulation of the plasma samples after the addition of venom. anticoagulant activities of venoms were also evaluated. total venom of echis carinatus showed anti coagulant activity in pt test, while its fractions showed procoagulant activity.

Isolation and partial purification of anticoagulant fractions from the venom of the Iranian snake Echis carinatus.

Many snake venoms comprise different factors, which can either promote or inhibit the blood coagulation pathway. Coagulation disorders and hemorrhage belong to the most prominent features of bites of the many vipers. A number of these factors interact with components of the human blood coagulation. This study is focused on the effect of Echis carinatus snake venom on blood coagulation pathway. ...
