        ABSTRACT     OBJECTIVE:To investigate the effects of Buyang huanwu decoction on hemorheology and platelet related
        biological indexes of hyperlipidemia model rats. METHODS:Male Wistar rats were randomly divided into blank control group(10
        rats)and model group(40 rats). Blank control group was given normal diet,and model group was given high-lipid diet for 6
        weeks at least to induce hypelipidemia model. After modeling,rats were randomly divided into model control group,positive
        control group(simvastatin,0.004 g/kg),Buyang huanwu decoction low-dose and medium-dose groups(3.5,14.0 g/kg,by crude
        drug),with 10 rats in each group. Blank control group and model control group were given normal saline intragastrically,
        administration groups were given relevant drug intragastrically,0.01 mL/g,once a day,for consecutive 4 weeks. Thirty min after
        last medication,hemorheological indexes(whole blood viscosity,plasma viscosity),platelet adhesion related indexes [adhesion
        rate,von Willebrand factor(vWF),fibronectin(FN)],platelet release related indexes [β-thromboglobulin(β-TG),platelet factor 4
        (PF4)] and platelet fibrinolytic system related indexes [tissue plasminogen activator (t-PA),plasminogen activator inhibitor
        (PAI-1)],platelet parameters(PLT,PDW,MPV,PCT,PLCR),4 kinds of coagulation parameters(APTT,TT,PT,FIB)were
        detected. RESULTS:Compared with blank control group,the whole blood viscosity(low,medium and high shear rate),plasma
        viscosity,platelet adhesion rate,the contents or levels of vWF,FN,β-TG,PAI-1,PLT,MPV,PCT,PLCR and FIB in model
        control group were increased significantly (P<0.05 or P<0.01),and t-PA content was significantly decreased (P<0.05).
        Compared with model control group,the whole blood viscosity(except for whole blood viscosity of high shear rate in Buyang
        huanwu decoction high-dose group),plasma viscosity,platelet adhesion rate,the contents or levels of vWF,FN,β-TG,PAI-1,
        PLT,PDW (except for Buyang huanwu decoction low-dose and high-dose groups),MPV,PCT,PLCR (except for Byang
        huanwu decoction low-dose group)and FIB were decreased significantly(P<0.05 or P<0.01),while t-PA content(except for
        positive control group) was increased significantly (P<0.05). CONCLUSIONS:Buyang huanwu decoction can significantly
        improve the pathological state in hyperlipidemia model rats by reducing blood viscosity and FN content,improving platelet
        adhesion,enhancing fibrinolytic activity,improving platelet aggregation,inhibiting hypercoagulability and hyperplatelet release.
