不同经穴TEAS对不同血压状态大鼠血压调节效应的比较

摘要

[目的]观察不同经穴经皮电刺激(TEAS)治疗对不同血压状态大鼠的血压调节效应.[方法]正常血压大鼠、自发性高血压大鼠和低血压模型大鼠,分别采用足三里、三阴交、太冲、曲池和合谷穴,运用经皮穴位电刺激疗法治疗,刺激参数为疏密波(频率2/100Hz)、强度4±1mA,时间为40min,每天治疗1次,连续治疗3天.无创测量大鼠的尾动脉收缩压.[结果]太冲穴刺激对正常血压有一定的降低作用,而其它四穴刺激无影响;上述五穴均能有效降低高血压大鼠的血压值,其中以太冲穴治疗为最佳、足三里穴次之;除合谷穴外,其它四穴能一定程度提高低血压模型大鼠的血压,其中以足三里穴治疗为最佳.[结论]五个常用的不同经穴对不同血压状态大鼠的血压水平有不同的调节效应,并存在双向调节的现象.%[Objective]To observe the effect of different TEAS on rats' blood pressure regulation.[Methods]For rats with normal blood pressure and self high blood pressure, respectively administer Zusanli,Sanyinjiao,Taichong,Quchi and Hegu acupoints with TEAS therapy;measure rats' tail artery contractive pressure invasively.[Result]Taichong acupoint stimulation can reduce definitely normal pressure;while other 4 acupoints have no effect; the 5 acupoints all can effectively reduce hypertensive rats' pressure,best in Taichong,then Zusanli, Hegu in order.[Conclusion]5 common acupoints with TEAS have different pressure regulation to hypertensive rats,with double-direction regulation.
