Objective To observe the change of myoelectricity ( ME) of rat jejunums whose islet A cells had been damaged, and analyzed the pathogenesis of enteroplegia to probe into internal relation between the Islet A cells and cholinergic nerve. 目的观察选择性破坏胰岛A细胞大鼠空肠肌电变化,分析肠麻痹的产生机制,探讨胰岛A细胞与胆碱能神经之间的内在联系。
Conclusions Emergence of enteroplegia is related to the reduction in acetylcholine. There are internal relations between islet A cells and the function of jejunum cholinergic nerves. 结论肠麻痹的发生与肠壁ACh减少有关,说明胰岛A细胞与空肠胆碱能神经功能之间存在内在联系。
Experimental Study on the Change of Myoelectricity and Enteroplegia of Rat Jejunums Whose Islet A cells of Islet Were Damaged 选择性破坏胰岛A细胞大鼠空肠肌电变化及肠麻痹的实验研究
Results The frequency and the rate of fast-wave reduced, and the appearance time of fast-wave was obviously later than the control group. Namely, the time of enteroplegia was obviously increased. 结果实验组大鼠肠电快波频率及快波出现率减少,肠电快波出现时间明显晚于对照组,即实验组肠麻痹时间明显延长。
