较大剂量照射后,在急性放射病的病程中,由于胃肠道的损伤及由此而产生的一系列问题,常常给治疗、护理工作带来许多困难。比较而言,肠上皮细胞的辐射敏感性很高,但肠上皮细胞的再生潜力很大,更新速度也很快。因此,深入掌握肠上皮辐射损伤与修复的规律性,对改善急性放射病的治疗原则,是有意义的。本文介绍大剂量丙线与中子混合照射狗的小肠上皮再生情况。 Large doses of radiation, in the course of acute radiation sickness, due to gastrointestinal damage and resulting a series of problems, often to the treatment, nursing work has brought many difficulties. In comparison, gut epithelial cells are highly radiosensitive, but intestinal epithelial cells have great potential for regeneration and are rapidly renewed. Therefore, in-depth understanding of the law of intestinal epithelial damage and repair of radiation, to improve the principles of treatment of acute radiation sickness, it makes sense. This article describes the large dose C and neutrons mixed irradiation dog intestinal epithelial regeneration.
