本遗传室对 2 0例小儿急性白血病 (AL)患儿进行骨髓细胞培养姐妹染色单体互换 (SCE)技术的观察研究。结果显示 :染色体各组之间姐妹染色单体互换频率比较 ,经方差分析处理有极显著性差异 (P <0 0 1)。急性白血病 (AL)组与正常组相比 ,SCE频率经方差分析处理有极显著性差异 (P <0 0 1)。
The hereditary room on 20 cases of children with acute leukemia (AL) in children with bone marrow cell culture sister chromatid exchange (SCE) technology observation study. The results showed that the frequencies of sister chromatid exchange among the groups were significantly different (P <0.01) by analysis of variance. Compared with the normal group, the frequency of SCE in acute leukemia (AL) group was significantly different (P <0.01) by analysis of variance.
