Chinese Veterinary Medicine B307 Promotes Cardiac Performance and Skeletal Muscle Contraction via Enhancing Intracellular Calcium Levels and Neural Electrical Activity in Animal and Cell Models

Figure 4

Comparison of contractile force and fatigue curve of the breast muscle in pigeons under sham and oral B307 treatments. (a) Contractile force of the isolated breast muscle in pigeons under sham treatment was obviously weaker over time than that of pigeons under oral B307 treatment. (b) Averaged fatigue curve of the breast muscle in pigeons under sham treatment was obviously steeper than that of pigeons under oral B307 treatment. Using a sham group of pigeons as a reference, the FF_50% and FT_50% are the contractile force and time at 50% of the fatigue curve. The values of the FF_50% and FT_50% were shown beside the curves. (c) Quantified FF_50% of the breast muscle in pigeons under sham treatment was significantly weaker than that of pigeons under oral B307 treatment , while FT_50% of the breast muscle in pigeons under sham treatment was significantly shorter than that of pigeons under oral B307 treatment . The numbers of pigeons under sham and oral B307 treatments were 3 for each group. Values are mean ± SEM (, one-way ANOVA followed by a Student–Newman–Keuls multiple comparison post hoc test).
