小肠是辐射敏感器官之一,急性辐射损伤时小肠运动功能出现明显紊乱,其变化程度与照射剂量有关。射线引起的小肠运动功能障碍前人已有报导。近年来不少学者提出急性放射病时由于肠套叠而引起的死亡是个值得重视的问题。不难看出,急性放射病时小肠运动功能紊乱对病程的发展和结局具有一定的影响。关于照射后小肠运动功能紊乱的机理,国内外学者曾做过一些研究。他们认为,照射后小肠运动功能 The small intestine is one of the radiation-sensitive organs. When the acute radiation injury occurs, the small intestine movement function appears obviously disordered, and its degree of change is related to the irradiation dose. Radiation-induced intestinal motility dysfunction has been reported previously. In recent years, many scholars put forward the death of acute radiation sickness caused by intussusception is a problem worth attention. It is not difficult to see that acute radiation sickness when the small intestine motor dysfunction on the course of the development and outcome have a certain impact. On the mechanism of small intestine dysfunction after irradiation, scholars at home and abroad have done some research. They think the small intestine motor function after irradiation
