摘  要:我们采用胞质分裂附断微核法对18例肿瘤放疗患者的淋巴细胞微核进行了检测分析。其中食管癌8例、肺癌4例、乳腺癌3例,其它肿瘤3例。微核检测分三次,即放疗前累积剂量达到30Gy和60Gy时。结果显示患者的平均微核率分别为15.6±6.6‰、65.1±19.0‰、122.6±35.8‰。所有患者血淋巴细胞微核率与照射剂量之间呈良好的线性关系。接受同等剂量照射的三组患者其组间微核率无明显差异。Abstract A study on micronucleus(MN) induction assay for 18 cancer patients followingradiotherapy by using cytokinesis-block micronucleus method was performed in 8esophageal cancers, 4 lung cancers, 3 breast cancers and 3 other cancers.Lymphocytes of the patients were analysed for MN frequency just before theradiotherapy, at 30Gy and 60Gy. The results showed that the mean frequencies(micronucleated binucleate cells in binucleated cells)were 15.6± 6.6‰, 65.1±19.0‰,122.6± 35.8‰at the doses of 0Gy, 30Gy and 60Gy, respectively. There were a linearrelationship between the radiation doses and the MN frequencies in all the patients.However, there was no significant difference among the MN frequencies of variousgroups of the patients who received the same radiation doses.
