| 摘 要： | 采用脉冲式电流刺激蟾蜍离体腓肠肌作为疲劳模型，研究银耳多糖对离体骨骼肌疲劳的影响。结果表明：较低浓度（0．05％、0．10％）的银耳粗多糖可以延长收缩幅度下降到最大收缩幅度90％、50％和10％的时间（P〈0．05）。较高浓度的银耳多糖（0．45g）可以缩短收缩幅度达到最大收缩幅度50％，10％的时间（P〈0．05）。适宜浓度的银耳粗多糖对离体骨骼肌的疲劳具有延缓作用。

| Abstract: | To investigate the effects of tremella polysaccharide on isolated skeletal muscular fatigue,we stimulated the isolated toad gastrocnemius by electric.the results showed that: the tremella polysaccharide at concentration of 0.05%,0.10% can prolong the time of contraction amplitude falling to 90%,50% and 10% of the max contraction amplitude(P<0.05).The tremella polysaccharide at concentration of 0.45% can shorten the time of contraction amplitude falling to 50% and 10% of the max contraction amplitude(P<0.05).So the conclusion is that the proper concentration of tremella polysaccharide has the effect of antifatigue. |
