Objective: To investigate the effects of blood-cooling and stasis-removing formula on hemorheology in rats with acute blood stasis induced by mutifactor stimuli. Methods: The selected SD rats orally took blood-cooling and stasis-removing granule for six days, then the model of acute blood stasis was prepared on the iffth day by injection of epinephrine combined with ice-water bath. The variations of blood-cooling and stasis-removing granule on hemorheology were detected. Results: The high-dose group of blood-cooling and stasis-removing formula can decrease plasma viscosity in rats with acute blood stasis, and obviously reduce the blood viscosity under the condition of shear rates (200s-1, 30s-1, 5s-1, 1s-1) (P<0.01,P<0.05). The middle-dose group can decrease the blood viscosity under the condition of shear rate (30s-1) (P<0.05). Conclusion: Blood-cooling and stasis-removing formula can improve abnormal hemorheology in rats with acute blood stasis.
