微核是细胞有丝分裂后期仍滞留在细胞质中的染色体断片或染色单体。随着微核形成机理和意义的阐明以及检测手段和实验技术的不断改进和完善 ,目前微核试验已被公认为筛选致突变物的主要方法之一[1 ] ,也是一种快速而敏感的检测染色体损伤的方法。外周血淋巴细胞是对电离辐射较
Micronuclei are chromosomal fragments or chromatids that remain in the cytoplasm at the late mitotic stage of the cell. With the elucidation of the mechanism and significance of micronucleus formation and the continuous improvement and improvement of detection methods and experimental techniques, the current micronucleus test has been recognized as one of the main methods for screening mutagens [1], and is also a fast and sensitive Detection of chromosomal damage methods. Peripheral blood lymphocytes are more ionizing radiation
