摘　　要：采用脉冲式电流刺激蟾蜍腓肠肌,将鸡腿菇多糖溶液组与任氏液组进行对比,探究鸡腿菇多糖对骨骼肌疲劳的作用。结果表明:鸡腿菇多糖能够延缓蟾蜍骨骼肌疲劳,质量浓度分别为0.16、 0.08、 0.04 g/L的鸡腿菇多糖溶液组离体、在体蟾蜍腓肠肌达到最大收缩幅度的90%、 50%、 10%的时间均明显长于任氏液组的;随着鸡腿菇多糖浓度的增加,骨骼肌收缩的时间也延长,呈现剂量依赖性的趋势。To investigate the effect of Coprinus comatus polysaccharide on skeletal muscle fatigue,the pulsed current was used to stimulate the gastrocnemius muscle of a toad,and the Coprinus comatus polysaccharide solution group was compared with Ringer’s solution group.The results show that Coprinus comatus polysaccharide can delay skeletal muscle fatigue of the toad.The time of Coprinus comatus polysaccharide solution group at mass concentrations of 0.16,0.08,and 0.04 g/L allowing the toad gastrocnemius muscle and the isolated toad gastrocnemius muscle to reach 90%,50%,and 10%of the maximum contraction is significantly longer than that of Ringer’s solution group.As the concentration of Coprinus comatus polysaccharide increases,the contraction time of skeletal muscle also prolongs,showing a dose-dependent tendency.
