前文曾报告了狗经丙线一次全身照射500rad(造血型)后空肠、回肠运动的变化。观察到在照后5天内无论空肠或回肠在收缩频率方面均与正常相似,但在照后1～2天内收缩幅度有所增强,以后渐次减弱,极期时肠运动可进入无收缩麻痹状态。在部分动物中出现极明显的收缩紊乱。动物可以在长时间无收缩状态中突然出现高张力、高幅度、阵发性紧张性收缩,收缩幅度可超过正常的
Earlier reported that the dog through the C line a total body irradiation 500rad (hematopoietic) after jejunum, ileum changes in exercise. Observed within 5 days after irradiation, both the jejunum or ileum in the contraction frequency are similar to normal, but within 1 to 2 days after irradiation, the contraction amplitude has increased, then gradually weakened, the extreme period of gut motility can enter the non-contracted paralysis state. In some animals there is a clear constriction disorder. Animals can suddenly appear in a state of no contraction for a long time, high tension, high amplitude, paroxysmal tension contraction, contraction can be more than normal
