摘要: 目的: 观察注射用羟基红花黄色素A(HSYA)对家兔血小板聚集功能及超微结构的影响。方法: 采用体内实验法,观察3种剂量的注射用HSYA (10、5和 2.5 mg/kg)对由花生四烯酸(AA)、二磷酸腺苷(ADP)和血小板活化因子(PAF)(3.6 nmol/L)诱导的家兔血小板聚集作用的影响,以及血小板超微结构的变化;并单独研究了以PAF为诱导剂的情况下,富血小板血浆(PRP)中α-颗粒膜蛋白-140(GMP-140)的含量。结果: 各剂量HSYA注射剂能抑制AA、PAF诱导的家兔血小板聚集(P<0.05,P<0.01);扫描电镜显示:各剂量HSYA注射剂能减少AA和PAF诱导后的聚集型血小板数量并使树突型血小板突起变少变短(P<0.05,P<0.01);另外,各剂量HSYA注射剂还能降低经PAF诱导后GMP-140的含量(P<0.01)。结论: 注射用羟基红花黄色素A具有显著的抗PAF诱导的血小板聚集作用,抑制血小板的活化,从而为临床抗血小板聚集药物的使用提供更多选择。

Abstract: AIM: To observe the effects of HSYA injection on platelet aggregation and ultra structure in rabbits. METHODS: In vivo experiments, when platelet activating factor (PAF) induced respectively, we observed the impacts of HSYA injection (10 mg/kg, 5 mg/kg and 2.5 mg/kg) on platelet aggregation, ultra structural changes of platelets and PAF-induced content of GMP-140. RESULTS: HSYA injection inhibited AA and PAF-induced platelet aggregation(P<0.05,P<0.01). Scanning electron microscope showed: HSYA injection could reduce the number of aggregation type plateles which were induced by AA and PAF; and make fewer and shorter processes of dendritic platelets(P<0.05,P<0.01). HSYA injection can reduce the content of GMP-140 in PRP(P<0.01). CONCLUSION: HSYA injection can antagonism PAF-induced platelet aggregation, inhibit the activation of platelets and reduce the content of GMP-140. Thus for, there will be more choices for clinical using of anti-platelet aggregation drugs.
