Abstract: Objective To discuss the function of Sijunzitang on relieving the exhaustion fatigue of muscle. Methods Thirty-two mice were divided into Quiet group,Fatigue group,Nature recovery group and Sijunzitang group. The mice in last three groups swam in the pool for 50 min every day. During exercise 0.2 mL Sijunzitang was injected into each mouse in Sijunzitang group every day. And the same dosage of normal saline was injected into other groups. After exercise, all the mice were killed and taken as material immediately. The technique of cytochemistry and Type MPV2 microspectrophotometer were used to test quantitatively the chemical components of different types (Ⅰ type, Ⅱ_A type and Ⅱ_B type) of muscle fibers in the quadriceps of mice after exhaustion exercise. Results After exhaustion exercise the content of glycogen and the activity of SDH in the muscle fibers in Fatigue group reduced remarkably (P<0.05 or P<0.01) compared with Quiet group.The content of glycogen and the activity of SDH in the muscle fibers in Sijunzitang group was significantly higher than that in Fatigue group (P<0.05 or P<0.01). Conclusion Sijunzitang can relieve the exhaustion fatigue of muscle and build up health.
