中文摘要:

采用胃体、胃窦、十二指肠和结肠浆膜下埋藏铂丝电极法,同步记录胃肠电活动,观察耳穴电针对家兔胃肠生理功能的影响。结果表明,耳针对胃肠道有兴奋和抑制的双相效应,该效应在不同个体和同一个体胃肠道不同部位同时存在。认为针刺对胃肠道功能活动具有不同生理节段、机能状态选择性的双相调整作用。对手针与电针,穴位与非穴位的针刺效应也作了讨论。

英文摘要:

The present investigation-was undertaken with electrophysiological methods to evaluate the effects of ear-acupuncture on gastrointestinal tract.24 rabbits weight 1.7～2.2kg were used.By applying dipolar leads of platinum,gastrointestinal electric activity on corpus,antrum,duodenum and colon were simultaneously recorded in animals.Ear-acupuncture effects were observed respec- tively with electric or manual acupuncture.Results:(1)Most of the rabbits’gastrointestinal electric activities(64.71～94.12%)display excitatory or inhibitory effects.The inhibitory effect was dominative,for example,the motility index(frequency×amplitude/3 min)on corpus,antrum, duodenum and colon was excitatory for 29.41～41.18%,and inhibitory 41.18～60.25%.The other subjects,after needling ear-point,were a few change or unchange on gastrointestinal activity.Their differences were significant(P<0.05～0.01).(2)The acupuncture effects were different in each individual and each segments of digestive tract.It was suggested that the modulatory effects of ear-acupuncture on functional activity of digestive tract were selected according to different func- tional conditions and physiologic segments.Furthermore,effects of electric and manual needles, acupoint and nonacupoint were some different,too.It seems that acupunctral effects possess quantitative and qualitative differences in excitation and specificity of acupoint.
