黄花倒水莲总皂苷对凝血系统及血栓形成的影响
Effect of Total Saponin from Root of Polygala fallax Hesml.(PTS) on Coagulation and Thrombosis
-
摘要: 目的:本文观察黄花倒水莲总皂苷(PTS)对凝血系统和炎症血栓的影响,为其临床应用于血栓性疾病提供一定依据。方法:采用体外家兔血浆复钙时间、凝血酶原时间、抗凝血酶时间、部分凝血活酶时间及小鼠凝血时间的测定,考察PTS对内、外凝血系统指标的影响,并通过角叉菜胶致小鼠体内血栓及足跖肿胀实验,观察PTS对炎症血栓的影响。结果:PTS可明显延长体外家兔血浆复钙时间;显著延长凝血酶所致纤维蛋白凝固时间;显著延长部分凝血活酶时间;对血浆凝血酶原时间无明显影响。预先ig给予PTS显著延长小鼠凝血时间;减小角叉菜胶所致尾部形成血栓的长度,同时明显抑制其足跖肿胀。结论:PTS可能通过影响内源性凝血系统发挥抗凝血及抗血栓作用。Abstract: AIM:To observe the effects of total saponin from root of Polygala fallax Hesml.(PTS) on coagulation and thrombosis.
