人的外周血染色体的培养技术已被广泛应用。业已证明,这一方法受到许多因素的影响。近年来,一些作者还证明,不同的培养时间,对一定数目的细胞的染色体畸变率的影响是十分明显的,这对辐射细胞遗传学的研究尤为重要。如按穆尔黑德(Moorhead)及其他作者的常规方法培养72小时后才进行收获,将使染色体真正的畸变率明显下降。为了今后进行系统的实验研究和对从事放射性作业的职工的染色体畸
Human peripheral blood chromosome culture technology has been widely used. It has been shown that this method is influenced by many factors. In recent years, some authors have also demonstrated that the effects of different incubation times on the chromosome aberration rate of a given number of cells are quite significant, which is of particular importance for the study of radiation cytogenetics. Harvesting for 72 hours, as routinely done by Moorhead and other authors, markedly reduced the true rate of chromosome aberrations. In order to carry out systematic experimental research and chromosome aberration to employees engaged in radioactive work in the future
