本文报道长耳白兔受单次与分次~(60)Coγ线不同剂量照射后一个月外周血 T 淋巴细胞 DNA 的合成能力。结果表明,单次照射各剂量组均在照后第1天 DNA 合成受抑最严重,照后第3天各组开始恢复,第7天各组都恢复到照前水平。当剂量率、累积剂量均相同,仅分次照射的次数不同时,0.05Gy/d 组受抑恢复比0.10Gy/d 组慢。
This paper reports the long-haired white rabbits were single and divided by ~ (60) Co γ-ray irradiation at different doses one month after the T lymphocyte DNA synthesis. The results showed that the DNA synthesis of each dose group was most severely inhibited on the first day after irradiation. Each group began to recover on the third day after irradiation. On the seventh day, all the groups returned to the pre-irradiation level. When the dose rate and cumulative dose were the same, only the times of different irradiation were different, 0.05Gy / d group was slower than the 0.10Gy / d group.
