Abstract:
Objective To analyze the protective effect of tanshinone Ⅱ A sodium sulfonate on rat skeletal muscle after exhaustive exercise in high temperature environment.Methods Ninety rats were divided into the observation group,blank group and control group,30 cases in each group.The rats in the blank group received no intervention,while which in the observation group and control group received the exhaustive exercise intervention under high temperature environment.The rate in the control group was injected with 8 mg/kg normal saline by femoral vein at 5 h after exhaustive exercise under high temperature environment,while which in the observation group was injected with 40 mg/kg tanshinone Ⅱ A sodium sulfonate by femoral vein.The arterial blood in each group was collected by tail vein before killing the rat,and the right leg gastroc nemius muscle of each group was removed and frozen.The serum CK,LDH activity,TNF-alpha,IL-6,IL-1β,MDA,SOD and GSH-PX levels in skeletal muscles were examined.The rat skeletal muscle samples were conducted the HE staining for observing the morphological change.Results The levels of serum TNF-α,IL-6 and IL-1β and activity of CK and LDH in the observation group were significantly lower than those in the control group,while higher than those in the blank group,the difference was statistically significant (P＜0.05).The skeletal muscle MDA,SOD and GSH-PX levels had statistical difference between the observation group and other two groups (P＜0.05).The skeletal muscle structure was disordered,and the distribution of muscle nuclei was uneven.The structure of rat skeletal muscle in the blank group was normal,and the muscle nuclei were evenly distributed.The morphology and structure of skeletal muscle in the observation group were normal,but the distribution of muscle nuclei was slightly uneven.Conclusion Tanshinone Ⅱ A sodium sulfonate can effectively protect skeletalmuscle after exhaustive exercise inhigh temperature environment.
