本文报导了1982年9月重庆大学高压实验室应用5—脱氧尿嘧啶核苷标记方法测定本室15名工作人员及重庆市X光医生外周血淋巴细胞姐妹染色单体互换发生率(S.C.E.Rate),分别为6.8次/细胞及5.8次/细胞(均高于国内外所测定正常人S.C.E.发生率)。数据经统计学处理,t值为3.733,即P<0.01,表明具有非常显著性差异。 我室测定结果证实:高电压实验室进行空气间隙放电操作过程中,室内确实存在造成工作人员外周血淋巴细胞染色体畸变因素存在,能对工作人员带来一定有害影响,并提示:S.C.E.技术以及测定染色体畸变技术对检测长期接触高压放电工作者的染色体的畸变效应都是敏感的。
In this paper, we report the prevalence of sister chromatid exchange among 15 workers in our laboratory and peripheral blood lymphocytes from X-ray doctors in Chongqing in September 1982 using a 5-deoxyuridine labeling method ), Respectively, 6.8 times / cell and 5.8 times / cell (both higher than the normal rate of SCE incidence in China and abroad). The data were statistically processed, t value was 3.733, P <0.01, indicating a very significant difference. My room measurements confirmed: high-voltage laboratory air gap discharge operation, the existence of indoor staff does exist in the presence of chromosomal aberrations in peripheral blood lymphocytes, the staff can have some harmful effects and prompts: SCE technology and determination Chromosomal aberrations are sensitive to the detection of chromosome aberrations in workers exposed to high voltage discharges over a long period of time.
