为观察脑组织受照射后的病理改变,分析其与临床的关系,作者用250KV、HVL 为1.3mmCu.剂量率为2Gy/分钟的X 线照射CFHB 鼠脑部。用双侧侧野照射,分别用单次20-42.5Gy 或31-75Gy/4次/4、10、30、40或60天方案照射各组鼠后,只对高剂量组的36只鼠进行了尸检和组织病理观察。尸检时鼠相当消瘦、多数比对照组体重下降50-65%,其中在死前4周内体重下降约30%。体表损伤仅见照射野内脱毛和眼周有干硬壳。查口腔有门齿变长、最为显著的上门齿变长达50-100%。另
To observe the pathological changes of brain tissue after irradiation, analyze the relationship with the clinical, the author with 250KV, HVL 1.3mmCu dose rate of 2 Gy / min X-ray irradiation CFHB rat brain. With bilateral side-field irradiation, the rats in each group were irradiated with single 20-42.5 Gy or 31-75 Gy / 4 times / 4,10, 30, 40 or 60 days respectively, Autopsy and histopathological observation. At the time of autopsy, the rats were quite wasting, most of whom lost 50-65% of the body weight of the control group, with about a 30% weight loss within 4 weeks before death. Surface damage is only seen in the field of hair removal and eye circumference dry hard shell. Check the oral cavity with incisors become longer, the most significant home door teeth change up to 50-100%. another
