The effects of the venoms of Naja melanoleuca, Naja nigricollis, and Ophiophagus hannah on blood coagulation, platelet aggregation, and fibrinolysis were studied in vitro. All three venoms were shown to be anticoagulant. This action appeared to be due to an effect on both the extrinsic and blood thromboplastin mechanisms. Platelet aggregation in Chandler's tubes and adenosine diphosphate reactivity were inhibited by the three venoms, although in the case of Ophiophagus hannah venom they were inhibited only with intermediate concentrations. The three venoms possessed proteolytic properties, but when incorporated into purified caseinolytic systems and euglobulin clot lysis systems inhibition of plasmin activity was observed.
研究了黑曼巴蛇、黑颈眼镜蛇和眼镜王蛇的毒液在体外对血液凝固、血小板聚集和纤维蛋白溶解的影响。结果表明,这三种毒液均具有抗凝作用。这种作用似乎是由于对外部和血液凝血活酶机制均有影响。三种毒液均抑制了钱德勒管中的血小板聚集和二磷酸腺苷反应性,不过对于眼镜王蛇毒液而言,只有在中等浓度时才会产生抑制作用。这三种毒液均具有蛋白水解特性,但当加入纯化的酪蛋白溶解系统和优球蛋白凝块溶解系统时,可观察到纤溶酶活性受到抑制。
