摘要
为阐明体表胃电图(electrogastrogram-EGG)与胃平滑肌电活动(gastromyoelectricactivi-ty-GEA)的相关性并探讨EGG的诊断学意义,用乌拉坦麻醉的大鼠,在胃的不同功能状态下同步记录了EGG和GEA。结果表明:EGG和GEA有高度相关性(P<0.01);静脉注射去甲肾上腺素使EGG和GEA的振幅同步下降,频率不变;由注射盐酸引致的胃窦部溃疡对EGG和GEA的频率与振幅无明显影响。结果提示,EGG只反映胃平滑肌的电活动而不能反映胃粘膜的病理变化。
n order to clarify the correlation between
electrogastrogram(EGG)and gastromyoelectricalactivity(GEA) and to study clinical significance
of EGG ,the experiment was carried out in therats anaesthetized with urethane. EGG and GEA
were recorded simultaneously at the variousfunctional states of the stomach. The results
obtained were as follows :There was high correlationbetween EGG and GEA(P<0.01).After
intravenous injection of noradrenaline,the amplitudesof both EGG and GEA were decreased
significantly,while the frequencies were not changed;Theantrum ulcer induced by injection HCl
to submucous layer did not affect the amplitudes and fre-quencies of both EGG and GEA. The
results indicate that EGG reflects only electrical activity ofthe gastric smoothmuscle,and can not
reflect pathological change of the gastric mucosa.
