摘要
目的:研究甲醛对人外周血淋巴细胞染色体的影响。方法:用不同浓度(5、25、125、500μmol/L)的甲醛溶液处理培养中的人外周血淋巴细胞,观察其微核率及SCE频率的变化。结果:低浓度(5、25μmol/L)甲醛处理后,人外周血淋巴细胞微核率和SCE频率与阴性对照组相比,无明显增加(P>0.05);而甲醛浓度(125、500μmol/L)较高时,细胞微核率和SCE频率均显著高于阴性对照组(P<0.05或P<0.01)。结论:较高浓度甲醛对人外周血淋巴细胞染色体有不同程度的损伤作用。
Objective:Effects of formaldehyde on peripheral lymphocyte chromosome out of human body was studied. Methods:Lymphocytes in culture fluid were treated by supplementing different doses (5, 25,125, 500 /通讯作者mol/L) of formaldehyde,then the changes of micronucleus and SCE rates were observed. Results: It is found that no significant increment in both Mieronucleus and SCE rates were detected at low doses of formaldehyde(5,25/μmol/L)in peripheral lym- phocytes( P 〉0.05) ;Micronucleus and SCE rates of test group were obviously higher than those of the negative control( P 0.05 or P 〈0.01) at the higher doses (125,500 μmol/L). Conclusion: formaldehyde may exert different degree of damage to peripheral lymphocyte chromosome out of human body.
