【摘要】：本研究探索了金针菇多糖是否具有延缓骨骼肌疲劳的作用.使用连续电刺激蟾蜍腓肠肌作为疲劳模型,比较金针菇多糖溶液和任氏液对蟾蜍腓肠肌疲劳的作用.研究显示,金针菇多糖在浓度分别为0.01mg/mL、0.04mg/mL和0.1mg/mL时,离体腓肠肌收缩幅度下降达到最大收缩幅度的90%、50%和10%的时间明显长于在任氏液作用下的离体腓肠肌(P0.01),并且三种浓度的多糖溶液延缓骨骼肌疲劳的作用具有剂量依赖性的趋势;0.04mg/mL的金针菇多糖溶液也极显著地延长了在体腓肠肌收缩幅度下降达到最大收缩幅度90%、50%和10%的时间(P0.01).上述结果表明,金针菇多糖溶液具有延缓骨骼肌疲劳的作用.
[Abstract]:This study explored whether Flammulina velutipes polysaccharides can delay skeletal muscle fatigue. The effects of Flammulina velutipes polysaccharide solution and Ren's liquid on fatigue of toad gastrocnemius muscle were studied by continuous electric stimulation of toad gastrocnemius muscle. The results showed that when the concentration of Flammulina velutipes polysaccharides was 0.01 mg / mL and 0.04 mg / mL, respectively, and the concentration of Flammulina velutipes was 0.04 mg / mL and 0.1mg/mL, The time of 90% and 10% of gastrocnemius muscle contraction decreased to the maximum contraction amplitude in vitro was significantly longer than that in isolated gastrocnemius muscle under the action of Ren's liquid, and the effect of three kinds of polysaccharide solution on delaying skeletal muscle fatigue was dose-dependent. The tendency of Lai was 0.04 mg / mL Flammulina velutipes polysaccharide solution also significantly prolonged the contraction of gastrocnemius muscle to the maximum contraction amplitude of 90% and 10% in vivo (P 0.01). The results indicated that Flammulina velutipes polysaccharide solution could delay skeletal muscle fatigue.
