不同粒度三七止血凝血作用比较研究

Comparative Study of Effects of Panax notoginseng (Burk.).F.H.chen Ponders with Different Diameters on Stopping Bleeding and Blood Coagulating

目的:探讨三七粒度大小对其药效的影响。方法:采用两种动物模型,测定各组小鼠出血时间及凝血时间。结果:同剂量三七粗粉和三七细粉之间止血时间相当,无显著性差异;凝血时间细粉组明显少于粗粉组。结论:三七细粉药效优于三七粗粉。

Objective ：To explore the effcet of granulation size on bioavailability .Methods：Two Animal models were used to determine the stanch bleeding time and the coagulantion time of every group. Results：The same dosage small size powder and big size powder of Panax notoginseng （Burk.）F. tt. Chen had the same stanch bleeding time,but had different coagulantion time. The time of the small size powder was shorter than the big size powder Conclusions：The small size powder of Panax notoginseng （Burk.） F. H. Chen has better effect than big size powder.
