大量的资料证明,许多物理、化学、生物因素可诱发染色体畸变。染色体畸变是潜在遗传危害的讯号,和人类肿瘤发生、流产、遗传性疾病有一定的关系。因此,自1960年体外周围血细胞培养方法建立以来,医学细胞遗传学的研究有了迅速的发展。资料表明,放射线不仅能诱发染色体畸变,而且在一定条件下染色体畸变率与射线有较好的线性关
A lot of data prove that many physical, chemical, biological factors can induce chromosome aberrations. Chromosomal aberrations are signals of potential genetic risk and have a relationship with human tumorigenesis, miscarriage and hereditary diseases. Therefore, since the establishment of the peripheral blood cell culture method in 1960, the research of medical cytogenetics has been rapidly developed. Data show that radiation can not only induce chromosomal aberrations, but also under certain conditions chromosome aberration rate and ray has a good linear relationship
