林蛙头多糖抗凝血活性的研究

目的探讨林蛙头多糖对凝血系统的影响。方法体外实验分别测定林蛙头多糖对复钙凝血时间、凝血酶原时间、凝血酶生成时间、凝血酶活性、水解纤维蛋白,激活纤溶酶原和对血凝块的影响。体内实验采用断尾法测定出血时间,玻片法测定凝血时间。结果林蛙头多糖在体外表现出显著的抗凝血效果,其作用随着浓度的增加而增强,但没有表现出溶栓作用。在体内能延长凝血时间和出血时间。结论林蛙头多糖在体内外均有抗凝血活性。

Anticoagulant Activities of Polysaccharides from the Heads of Rana temporaria chensinensis

Objective To investigate the anticoagulant effect of polysaccharides from the heads of Rana temporaria chensinensis(Chinese Forest Frogs). Methods In-vitro experiments were applied to test the effect of polysaccharides on recalcification time, prothrombin time, thrombase time , the activities of thrombin, hydrolyzing fibrin content, activated fibrin dissolve zymogen and blood clotting.. In the in-vivo experiment, bleeding time was measured by cutting mouse tail and clotting time was measured by glass sheet method. Results The polysaccharides from the heads of Chinese Forest Frogs had an obvious anticoagulant effect in a dose-effect manner, but had on thrombolytic action. It could prolong the bleeding time and the clotting time in vivo. Condusion The polysaccharides from the heads of Chinese Forest Frogs have the anticoagulatant activities in vitro and in vivo.
