注射用血栓通对高脂血症家兔血小板功能的影响

目的研究注射用血栓通(冻干,主要成分为三七总皂苷,质量分数为95%)对实验性高脂血症家兔血小板功能的影响。方法家兔喂食高脂饲料2周造模,造模后给药组分别iv给予血栓通6.25、12.50、25.00 mg/kg,每天1次,连续14 d后,各组家兔颈总动脉取血,制备血清或血浆,测定血小板功能。结果血栓通能降低高脂血症家兔血脂水平;抑制二磷酸腺苷二钠盐(ADP)、花生四烯酸钠盐(AA)、胶原诱导的血小板聚集,降低聚集曲线斜率,并能延迟聚集时间;降低高脂血症家兔血浆中血管内皮细胞黏附分子-1(VCAM-1)、血小板因子4(PF4)和P-选择素水平;延长部分活化凝血活酶时间(APTT),降低血浆纤维蛋白原(FIB)水平。结论注射用血栓通体内具有抗血小板聚集的作用。

Effect of Xueshuantong Injection on platelet function of rabbits with hyperlipemia

Objective To investigate the effect of Xueshuantong Injection (lyophilized, main constituents are total saponins of Panax notoginseng with content of 95%) on the platelet function of rabbits with hyperlipemia . Methods The model was made by giving the food with high fat to rabbits for 2 weeks, then Xueshuantong Injection (6.25, 12.50, and 25.00 mg/kg) was iv given once daily for 14 d and the function of platelet was tested after preparing serum and plasma by taking blood form carotid artery. Results Xueshuantong Injection could reduce blood lipid levels, inhibit the platelet aggregation induced by ADP, AA, & COLL, and reduce the aggregation curve slope & the aggregation delay; lower the expression levels of VCAM-1, PF₄, and P-selectin; prolong the APTT, and decrease the level of FIB. Conclusion Xueshuantong injection (lyophilized) has the anti-aggregation function.
