Methods The bone marrow cells of pure Kumming species of mice were used as experimental material in which the micronucleusand sister chromatid exchanges induced by cyclophosphamide were used as an index.

方法以昆明纯种小鼠的骨髓细胞为实验材料，用公认的诱变剂环磷酰胺诱发的微核率和姐妹染色单体互换频率为指标，研究EGCG对CP诱导小鼠骨髓细胞MN和SCE的影响。

Methods: Peripheral blood lymphocytes from 30 women of childbearing age working with VDTs were cultured and conducted sister chromatid exchange and micronucleus analysis.

随机选择VDT作业及对照组的育龄妇女各30例，对其外周血淋巴细胞分别按姐妹染色单体互换检测方法及微核检测方法进行培养、检测。

Methods: The expression of mutated P53 gene in human lymphocytes was investigated using flow cytometry.And the micronucleus and sister chromatid exchange tests were studied in vitro.

以正常人外周血淋巴细胞为材料，用流式细胞仪检测环磷酰胺对突变型P53基因表达的影响，同时以微核及姐妹染色单体互换为指标，进行致突变研究。

The percentage of the cell observed chromosome lagging in A1 and the percentage of abnormal cell in TI showed a greatly significant positive correlation. That may demonstrate chromo

相关分析表明后期Ⅰ染色体滞后细胞比率同末期Ⅰ异常细胞比率呈极显著的正相关，推测后期Ⅰ染色体分离和末期Ⅰ微核形成可能是由相同的显性单基因或主效基因控制。

The distilled water and potassium dichromate (0.05%) were used as the negative and positive control respectively.
