摘要/Abstract

摘要： 利用体表电极、体内胃肠电极和压力传感器,通过计算机分别同时记录正常对照组和急性应激组Wistar大鼠体表胃电、体内平滑肌慢波和胃平滑肌运动信号,并进行数据处理和统计学分析。结果表明,正常对照组和急性应激组的体表胃电、体内平滑肌慢波和胃平滑肌运动存在差别。这种差别提示：①体表胃电在一定程度能够反映胃的活动,揭示胃的生理和病理规律,有可能应用于临床,作为胃病的诊断和疗效判定的客观标准；②体表胃电不仅反映体内胃平滑肌慢波的电活动,还与胃平滑肌运动有关,反映了有关胃平滑肌运动的一些信息。

关键词: 体表胃电, 体内平滑肌慢波, 胃平滑肌运动, 时-频分析

Abstract: The cutaneous electrodes, gastric electrodes and strain gauges were used to record the cutaneous gastroelectric activity, gastroelectric smooth muscle slow wave and gastric circle muscle motility in Wistar rats of the control group and the acute stress group through computer, respectively. The data were delt with by time-frequency analysis, and statistics analysis. The differences of the two groups suggested that: ①Cutaneous electrogastrography could reflect the gastric activities, reveal gastric physiological and pathological laws, be applied in clinic as an objective standard to diagnose gastric diseases and evaluate the therapeutic effect to a certain degree. ② Cutaneous electrogastrography reflected not only the electric activities of gastric smooth muscle, but also some information about gastric circle muscle motility.

Key words: electrogastrography, slow wave, gastric motility, time-frequency analysis
