我们以往工作观察到大鼠全身照射800拉德后早期腹泻发生率很高,与此同时小肠运动显著增强,自发活动与对乙酰胆碱和烟碱的反应明显增高,提示此时可能有肠道植物神经功能的变化。为进一步了解照后肠运动功能障碍发生的机制,我们对照后肠道副交感神经功能作了一些探索。 Our previous work observed a high incidence of early diarrhea in rats after irradiation with 800 rads, and at the same time significantly increased intestinal motility, spontaneous activity was significantly increased response to acetylcholine and nicotine, suggesting that there may be intestinal autonomic nerve Functional changes. To further understand the mechanism of occurrence of hindgut dysfunction, we made some exploration on the function of the parasympathetic parasympathetic nerves.
