细胞辐射敏感性的预测一直是放射生物学和肿瘤治疗研究领域的重要内容 ,是肿瘤放射治疗方案尤其放疗个体化方案制定的关键。在动物实验和临床研究中 ,已提出了许多检测细胞内在放射敏感性的方法[1 ] 。其中微核 (ＭＮ)检测法是被广泛应用的方法之一[2 ,3 ] 。但是人们仍对将其 The prediction of cell radiation sensitivity has been an important part in the field of radiobiology and tumor therapy research, and is the key to formulating individualized radiation therapy programs, especially radiotherapy. In animal experiments and clinical studies, many methods for detecting intrinsic radiosensitivity of cells have been proposed [1]. Micronucleus (MN) detection is one of the widely used methods [2, 3]. But people are still right about it
