摘要:

目的: 探讨邻苯二甲酸二(2-乙基己)酯(DEHP)对小鼠肺细胞DNA的损伤作用。方法:以生理盐水作为阴性对照组,用不同浓度DEHP(5、25、125、625 μmol/L)对小鼠肺细胞进行体外染毒,应用单细胞凝胶电泳技术检测肺细胞DNA的断裂程度。结果:当DEHP的浓度为125和625 μmol/L时,肺细胞尾部DNA百分含量、尾矩和Olive 尾矩与阴性对照组相比均升高,差异具有统计学意义(P<0.05)。结论:DEHP在体外可造成小鼠肺细胞的DNA断裂损伤。

Abstract:

OBJECTIVE: To study DNA damage induced by di (2-ethylhexyl) phthalate (DEHP) to mice lung cells. METHODS:The negative control group was exposed to saline. Extracted mice lung cells were exposed to different concentrations of DEHP(5,25,125,625 μmol/L) and single cell gel electrophoresis was used to test the DNA breakage degree. RESULTS:Compared with the control group,tail DNA percentage,tail moment and Olive tail moment of 125 μmol/L and 625 μmol/L DEHP-treated groups were increased significantly (P<0.05). CONCLUSION: DEHP could induce DNA breakage of mice lung cells in vitro.

Key words: di(2-ethylhexyl) phthalate, single cell gel electrophoresis, lung cells, DNA damage
