普通成年人体表结肠电的空腹水平及餐后反应

Electocolonogram of Healthy Adults on Fasting Condition and Postprandial Response

应用“微电脑胃肠电检测分析系统”观测76名普通成年人体表升、降、乙状结肠肠电,作频谱分析并分别低、高频段计算频谱累加值,以代表结肠电活动量。各段结肠低、高频段活动量具有各自不同的功能意义。统计结果显示,受检者空腹结肠电有活跃期和安静期两种活动状态,前者动量为后者5～7倍,发生时间1:9。约75％受检者餐后10～20分钟结肠电活动量较空腹安静期明显增大至3.4～6.1倍,属健康人的快速反应;10％左右受检者餐后反应迟缓并减弱;其余15％的反应介于以上两类之间。另外还发现10.1～26.2％受检者餐后30～40分钟时活动量再次升高,呈双相反应。本文的资料定量地反映了健康人大便正常者空腹和餐后结肠的运动电活动状态,并可推导有关神经体液因素的调节过程。报告的数据除具有生理意义外,尚可在结肠病理生理研究、临床结肠电检查以及中医肝脾大肠虚实辨证中作为正常对照值使用。

Electrocolonograms(EcoGs) of ascending, descending and sigmoid colons of 76 healthy adults were detected and frequency-spectrum analysis was made. The results showed there were quiet and active states of ECoGs on fasting condition. In about 75％ objects, action of ECoCs 10-20 minutes after test meal increased significantly to 3.4-6.1 times of that in fasting quiet state, which was a ncrmal response. The rest 15％ and 10％ showed slow or even slower responses. In addition, 10.1-26.2％ of the total objects were found to have two-phase response, which indicated that two peaks of ECoG action increased during 40 minutes after test meal.
