本室多次研究证明,受孕13 d大鼠(相当人孕8周)进行一次100 R全身照射,引起胎鼠发育迟缓、脑重减轻、脑体积变小与对照组比较有显著性差异。脑(带脊髓)组织学光镜检查,发现端脑部分颞叶皮质(如海马下托等)和嗅球腹内侧面受损,形成许多细胞团块,为了进一步了解上述变化对生后F_1代仔鼠行为发育的影响,将受孕Wistar大鼠随机分为三组:对照组(未照射)、照射组(照射100 R)及照后给药组,于分娩前单笼饲养,仔鼠出生后试验项目有称体重(1、3、5、
Many studies in this laboratory have shown that after a 13-day pregnancy (a considerable number of people were 8 weeks pregnant), a total body irradiation of 100 R caused fetal rat growth retardation, brain weight reduction, and smaller brain volume compared with the control group. Histological light microscopy of the brain (with spinal cord) revealed that the cortex of the temporal lobe (such as the hippocampus, etc.) and the olfactory bulb were damaged in the ventral side of the olfactory bulb, forming many cell clumps, in order to further understand the above changes on the postnatal F_1 generation The influence of behavioral development in rats, pregnant Wistar rats were randomly divided into three groups: control group (non-irradiated), irradiation group (irradiation 100 R) and post-irradiation group, single cage feeding before delivery, postnatal test The project has weight (1, 3, 5,
