四种蒲黄对凝血系统作用的比较研究

Comparision Among Four Species Puhuang on Blood Coagulation System in Vivo and Vitro

通过对小鼠、大鼠的凝血时间，凝血酶元时间及血小板聚集性等试验表明，4种蒲黄均具有促凝血的作用。其中以长苞香蒲作用最强。其次为蒙古、宽叶、窄叶香蒲。它们的作用机理也不完全一致。长苞香蒲主要促进凝血酶元激活，蒙古香蒲则主要在于促进血小板聚集性。

Test on coagulation time,prothrombin time and platelet aggregation of mice and rats showed that all four species of Puhuang had effects on blood coagulation, in which Typha angustata Bory et Chaub. was the strongest followed by T. davidiana Hand. -Mazz., T. latifolia L,and T. angustifolia L. Their mechanism of coagulation were not the same,in which T. angustata Bory et Chaub. mainly acted on thrombogen,while T.davidiana Hand. -Mazz. mainly acted on platelet aggregation.
