黏膜接触电极在家兔Oddi括约肌肌电测量中的应用价值

目的 探讨适合Oddi括约肌（sphincter of Oddi,SO）肌电测量的新方法.方法 两组各15只家兔分别用黏膜接触电极（contact electrode on mucosa,CEM）和浆膜钩状电极（chorion claw electrode,CCE）测量SO肌电活动;另外6只家兔同时使用两种电极同步测量.结果 CEM测量SO肌电成功率高,创伤小,而且记录到的家兔SO肌电波形和CCE相比没有明显的差别.结论 CEM是一种很有价值的测量SO肌电活动的新方法,将来可能用于人体SO功能的研究,为人体内镜诊断SO功能提供了一个新方法.

Value of mucous membrane contact electrode for electrophysiological measurement of Oddi's sphincter in rabbits

Objective To explore a new method of eleetrophysiological measurement for Oddi's sphincter function.Methods Thirty adult rabbits were divided into 2 groups with 15 in each.The e- lectric activily of Oddi's sphincter was recorded by the comact electrode on mucosa(CEM)in group A and that by the chorion claw electrode(CCE)in group B.In another 6 rabbits.rnyoelectric activity was simuhaneously recorded by the 2 methods(group C).Results The rate of success of electro- physiological measurement in rabbits could be increased by using CEM.Meanwhile,the electric activi- ty of Oddi's sphincter recorded by CEM was similar to that recorded by CCE.Conclusions CEM seems to be a valuable technique for determination of Oddi's sphincter function and can be used as a new method for endoscopic determination of Oddi's sphincter function in human being.
