在急性辐射损伤的防治研究中,如何直接地应用人体细胞的有关实验来定量地评价有效的辐射防治药物,这乃是当前一项十分重要的研究课题。本文报导了DNA 对人体细胞离体经受~(60)Coγ线不同剂量照射的染色体畸变效应的实验结果。实验中,任选了四名表型正常,身体健康的献血员作为受检者(C),各取血4毫升,血细胞体外培养方法及染色体畸变的观察、统计、分 In the study of prevention and treatment of acute radiation injury, how to directly evaluate the experiment of human cells to quantitatively evaluate effective radiation preventive drugs is a very important research topic at present. In this paper, we report the experimental results of DNA on chromosome aberration induced by different doses of ~ (60) Coγ in vitro. In the experiment, four blood donors with normal phenotype and good health were selected as subjects (C), 4 ml of each blood was collected, the method of in vitro culture of blood cells and the observation and statistics of chromosome aberration
