    Abstract:
    OBJECTIVE: To comparatively assess the effects of angelica root and chuanxiong on the hemorheology and the blood coagulation function in acute blood stasis rats. METHODS: Ice water bath and subcutaneous injection of adrenaline were both used to establish the acute blood stasis rat model. The whole blood viscosity, plasma viscosity, erythrocyte sedimentation rate (ESR), and haematocrit were tested to observe the effects of angelica root and chuanxiong on the hemorheology of blood stasis rats. The prothrombin time (PT), activated partial thromboplastin time (APTT), and plasma fibrinogen (FIB) were tested to observe the effects of angelica root and chuanxiong on the blood coagulation function of blood stasis rats. Finally all those indices were integrated to the total activating blood circulation effect value to assess the total effects of angelica root and chuanxiong on activating blood circulation and dissipating blood stasis. RESULTS: Compared with the normal control group, the hemorheological indices obviously increased, PT and APTT were obviously shortened, and the FIB content obviously increased in the model group. Compared with the model group, the water extracts, alcohol extracts, water-alcohol extracts of angelica root, chuanxiong, angelica root and chuanxiong 1:1, and angelica root and chuanxiong 1.5:1 could decrease the hemorheological indices, prolong the PT and APTT, and significantly reduce the content of FIB. Under the condition of the same preparation method, the alcohol extract of angelica root and chuanxiong 1:1 showed the best total effect. As for the single herbs, chuanxiong had better effect than angelica root on the total effects of activating blood circulation and dissipating blood stasis. Under the condition of the same ratio, the alcohol extracts of angelica root and chuanxiong showed better total effects of activating blood circulation and dissipating blood stasis than water extracts and water-alcohol extracts. CONCLUSION: The angelica root and chuanxiong could obviously improve the abnormality of hemorheology and blood coagulation function in acute blood stasis rats, thus providing evidence for revealing the scientific innovation of the compatibility of angelica root and chuanxiong.
