褐毛甘西鼠尾注射液对兔血小板功能的影响

Study of the Effect of S.Przewalskii Maxim var Mandarinorum Stib on Platelet Function in Rabbits

目的:观察云南产褐毛甘西鼠尾对血小板聚集率的影响。方法:采用Born氏比浊法,观察褐毛甘西鼠尾及丹参体内、体外对抗ADP、PAF、AA诱导的兔血小板聚集的作用;体内实验分为7组,即生理盐水组、两种丹参各以5、10、20g/kg剂量组,每组6只。结果:(1)与对照组相比,褐毛甘西鼠尾、丹参体外显著抑制ADP、AA诱导的血小板聚集,抑制效应呈浓度-效应关系,IC50分别为褐毛甘西鼠尾55.4g.l-1(ADP)、14.3g.l-1(PAF)、丹参49.6g.l-1(ADP)、14.1g.l-1(PAF),两种丹参也显著抑制PAF诱导的血小板聚集,其最大抑制率为褐毛甘西鼠尾24.8%、丹参22.4%;体内实验结果显示,两种丹参在高剂量时可显著抑制ADP、PAF和AA诱导的血小板聚集(P<0.05,0.01);且均具有剂量依赖性。40min达到最大抑制作用,抑制率分别为褐毛甘西鼠尾65.8%(ADP)、47.6%(PAF)和51.3%(AA),丹参62.3%(ADP)、43.5%(PAF)和50.2%(AA),褐毛甘西鼠尾和丹参无显著差异。结论:以上结果表明,褐毛甘西鼠尾和丹参具有明显的抗血小板聚集作用,为进一步开发和利用滇产丹参提供了依据。

Objective:To study the effect of S.Przewalskii Maxim var mandarinorum Stib on platelet aggregation.Method:42 rabbits were randomly divided into seven groups,every group have six.The rabbit platelet aggregation was evaluated with Adenosin Diphosphate(ADP).Platelet Activating Factor(PAF).Arachidonic Acid(AA)as inducing agents in vitro or in vivo.The central venous blood samples was collected from artery at 20,40,60,120,180,240min.Result:Compared with the negative group,the treated groups markedly inhibited ra...
