Muscle strength of tibialis anterior muscle in vitro and histological structure of gastrocnemius muscle. a: Contractility of tibialis anterior muscle in vitro. *indicates p < 0.05. b: Histological structure of gastrocnemius in the model group. Black arrows indicate enlarged muscle fiber spaces. Magnification: × 200. c: Histological structure of gastrocnemius in the control group. Magnification: × 200. d: Comparison of normalized CSA of gastrocnemius muscle fibers between two groups of rats. *indicates p < 0.05. CSA, cross-sectional area; MG, model group; CG, control group
