本文采用ＤＮＡ琼脂糖凝胶电泳研究了２３５Ｕ诱发的免疫细胞（人淋巴细胞白血病细胞株Ｍｏｌｔ－４细胞和巨噬细胞株Ａｎａ－１细胞）凋亡，探讨了细胞因子ＩＬ－２和ＩＬ－６的防护作用。结果表明，经２３５Ｕ照射达６ｈ以上的各组Ｍｏｌｔ－４和Ａｎａ－１细胞，均可观察到呈现凋亡细胞特征的阶梯状条带形成；而预先使用细胞因子ＩＬ－２和ＩＬ－６，对２３５Ｕ诱发的免疫细胞ＤＮＡ链断裂有显著的防护作用。
In this paper, the apoptosis of 235U induced immune cells (human lymphoblastic leukemia cell line Molt-4 and Ana-1 cells) was studied by DNA agarose gel electrophoresis. The effects of cytokines IL-2 and IL-6 The protective effect. The results showed that ladder-shaped bands with apoptotic cells could be observed in all the Molt-4 and Ana-1 cells irradiated with 235U for more than 6h. However, cytokines IL-2 and IL-6, 235U induced immune cell DNA strand breaks have a significant protective effect.
