低频电针促胃电节律规整性的腧穴筛选研究

Low Frequency Electroacupuncture Stimulating Regularity of Gastric Myoelectrical Activity for Points Selection in Rabbits

为比较足三里、内关、脾俞 3穴不同组合的低频电针对家兔胃电节律规整性的影响 ,通过胃壁浆膜下电极引导家兔胃电 ,进行计算机频谱分析 ,以正常频段能量比为频域指标对低频电针促胃电节律规整性进行观察 ,结果 7种选穴均能不同程度地对抗因束缚引起的短暂性胃电节律规整性下降 ,其中 3穴组合组效应最显著(P<0 .0 5) ,内关 1穴组亦呈现较好作用。说明电针足三里、内关、脾俞的 7种不同组合均能提高胃电正常频段能量比 ,使胃电节律更规整。

To study the different effects of low frequency electroacupuncture in comparison with random combination of “ZUSANLI”(ST36),“NEIGUAN”(PC6),“PISHU”(BL20)(seven groups respectively,ie one point group,two points group and three points group),throught the computer spectrum analysis of rabbit Gastric Electrogastrogram (EGG) which resulted from electroacupuncture on gastric parietal subserosa,the effects were observed and the percentage of normal slow waves used as index.The results showed that the transient irregularity of EGG caused by bound could be inhibited to different extent by low frequency electroacupuncture among the seven groups.The effects were the most obvious in the three points group and that of only NEIGUAN points run the second.It indicates that low frequency electroacupuncture on the effective points can improve the percentage of normal slow waves of EGG and regulate EGG.
