摘要
[目的]探讨黄芪酒精提取液对大鼠骨骼肌收缩力的影响.[方法]灌胃给予200 mg/kg黄芪酒精提取液2周后,观察大鼠坐骨神经受刺激后腓肠肌及比目鱼肌的收缩力.[结果]黄芪酒精提取液缩短腓肠肌及比目鱼肌单收缩和完全性强直收缩潜伏期,增加单收缩最大收缩幅度,延长最大收缩时间及最大舒张时间;增加完全性强直收缩的最大收缩度,延长最大收缩时间.[结论]黄芪酒精提取液可增强大鼠骨骼肌的收缩力.
OBJECTIVE To study the effects of ethanol extract of the Huangqi on the skeletal muscles contractility in rats. METHODS The gastrocnemius and soleus muscle contractility were observed by stimulating the sciatic nerve with electricity after affusing stomach with ethanol extract of the 200 mg/kg dosage of Huangqi for 2 weeks. RESULTS The ethanol extract of the Huangqi could shorten latent period, increase maximal contractive extent and time and relaxative time at the twitch and complete tetanus of gastrocnemius and soleus muscles. CONCLUSION The ethanol extract of the Huangqi can enhance skeletal muscles contractility in rats .
