| 摘 要： | 目的探讨穴位电刺激疗法对大鼠急性运动后腓肠肌收缩功能的影响。方法 45只SD大鼠,随机分成三组,适应性游泳训练1星期后,进行急性运动（2 h的游泳）,全麻下取腓肠肌,应用差速离心法提取SR,检测肌质网（SR）钙泵（Ca2＋-ATPase）、Ca2＋浓度;30只SD大鼠,随机分成正常对照组、急性运动模型组、穴位电刺激治疗组三组,运动后制备坐骨神经-腓肠肌标本,在SMUP-E型生物信息处理系统上观察腓肠肌最大收缩力。结果模型组大鼠腓肠肌SR Ca2＋-ATPase的活力明显低于对照组（P〈0.05）,治疗组则明显高于模型组（P〈0.05）;模型组大鼠腓肠肌SR Ca2＋浓度明显高于对照组（P〈0.05）,治疗组则明显低于模型组（P〈0.01）,治疗组与对照组差异无统计学意义（P〉0.05）;模型组大鼠腓肠肌的最大收缩力明显小于对照组（P〈0.05）,而治疗组则明显大于模型组（P〈0.05）。结论一次性急性游泳（2 h）大鼠腓肠肌SR的Ca2＋-ATPase活性明显下降,Ca2＋浓度显著升高,腓肠肌的最大收缩力下降;穴位电刺激则可以明显提高大鼠腓肠肌SR Ca2＋-ATPase的活力,降低SR内Ca2＋浓度,增强大鼠腓肠肌的最大收缩力。这可能是穴位电刺激疗法延缓运动疲劳的机理之一。

| Abstract: | Objective To explore the effect of acupoint electrostimulation on gastrocnemius contractility in rats after acute exercise.Methods Forty-five SD rats were randomly allocated to three groups.Acute exercise(2 hr swimming) was done after adaptive swimming training.The gastrocnemius was taken under general anesthesia.The sarcoplasmic reticulum(SR) was extracted by differential centrifugation.SR calcium pump(Ca2+-ATPase) and Ca2+concentration were measured.The 30 SD rats were randomly allocated to three groups: ... |
