目的观察■虫对大鼠血小板聚集程度和凝血时间的影响。方法以脑血康口服液为阳性对照药,以虫生药粉组、水提液组为治疗给药组,测定各组大鼠血小板聚集程度和凝血时间。结果各给药组在给药后血小板聚集程度增加,明显高于空白对照组(P<0.05),但凝血时间组间比较无明显差异。结论虫可增加大鼠血小板聚集程度,与以往报道不一致,其中水提液组作用明显。表明虫活血化瘀的主要作用可能不在于抗凝血方面。 Objective To observe the effect of worms on platelet aggregation and clotting time in rats. Methods NaoXangkang oral liquid was used as positive control drug, acarid powder group and water extract group as treatment group. Platelet aggregation and coagulation time were determined in each group. Results The level of platelet aggregation increased after administration in each drug-administered group, which was significantly higher than that of the blank control group (P<0.05), but there was no significant difference between the coagulation time groups. Conclusion Aphids can increase the platelet aggregation of rats, which is inconsistent with previous reports. The effect of water extract is obvious. The main effect of the aphid to promote blood circulation and phlegm-removal may not be anticoagulation.
