摘要

用不同剂量（0～3 Gy）,60,Co γ射线一次全身性照射雌性ICR小鼠，观察MⅡ（第二次减数分裂中期）卵母细胞和骨髓细胞染色体损伤效应，用WHO推荐的4个模式进行剂量效应曲线的拟合，选出最优的拟合模式，并对MⅡ卵母细胞和骨髓细胞的量效关系式进行了比较。结果表明，MⅡ卵母细胞和骨髓细胞均为辐射的敏感指标。骨髓细胞的辐射敏感性高于MⅡ卵母细胞。

Abstract

Chromosome aberrations induced by various ,60,Co γ-ray doses(0~3 Gy) were examined in secondary oocytes and bone marrow cells of ICR mice. The chromosome aberration rates of the two cell lines were both significantly higher in γ-irradiated groups than that in control ones. Using four models recommended by WHO, dose-response calibration curves were established and better matches were selected: they were ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004025&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004028&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004026&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004040&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004042&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=43004030&type=, for aberrant cell and total chromosome aberration rates(%) of oocytes, respectively.

A comparison of radiosensitivity between MⅡ oocytes and bone marrow cells were also made, the results showed that both MⅡ oocytes and bone marrow cells were sensitive, the bone marrow cell radiosensitivity was higher than that of MⅡ oocytes by 2.2 times.
