Objective: To study the effects of Huoxue Cuyu capsule on acute soft tissue injury in rats with acute blood stasis. Method: The rat model with acute blood stasis was estalished by freely falling mass damsges models. After modeling

rats were at random divided into model control group

Sanqi capsule control groups

low dose group

middle dose groups and high dose group(2.75

8.25

16.50 g·kg-1)of Huoxue Cuyu capsule

10 rats each group. calf circumference and the threshold value of mechanical stimulus in injuries was tested every day. Rats were treated with oral medication daily for 5 days

the visual observation of local tissue damage

histological examination

determination of blood viscosity was made. A normal control group was set up in addion. Result: Huoxue Cuyu capsule had an apparent effect on acuting soft tissue injury in rats with acuting blood stasis

easing the suffer in soft tissue injury from the mechanical stimulus

reducing the blood viscosity

and increasing the erythrocyte aggregation index

also it had an obvious utility in reparing the soft tissue injury. Conclusion: Huoxue Cuyu capsule is benefit for acuting soft tissue injury from blood stasis.
