BM13505对血小板聚集和血栓形成的影响
EFFECTS OF BM13505 ON PLATELET AGGREGATION AND THROMBOSIS
【摘要】 BM13505在体外对花生四烯酸(AA)诱导的家兔血小板聚集有抑制作用且呈剂量依赖性,其IC50为20μmol/L;对 ADP 和胶原诱导的血小板聚集则无显著影响。大鼠 ivBM13505 0.23mg/kg 能显著,延长血管闭塞时间,与阿司匹林30mg/kg 药效相近。小鼠 ivBM13505 1.13mg/kg 可明显延长尾出血时间效应与阿司匹林30mg/kg 相近。
【Abstract】 In vitro,BM13505 dose-depedently inhibited AA induced (but notADP and collagen) platelet aggregation in rabbits with IC50 20μmol/L.In rats,BM13505 prolonged the occlusion time (OT) greatly.In mice,BM13505 increasedtail bleeding time in a dose-dependent manner.BM13505 0.23 and 1.13 mg/kgproduced effects similar to aspirin 30 mg/kg in rats and mice respectively.
