中文摘要:
      为了研究1,2,4- 三氯苯(1,2,4-TCB)对斑马鱼(Danio retio)肝细胞DNA 的损伤作用,采用不同浓 度的1,2,4-TCB 溶液(0、1、5、10 mg/L)对体外培养肝细胞进行染毒,应用单细胞凝胶电泳(彗星实验)检测肝 细胞DNA 的损伤效应。结果发现,染毒2 h 后,与对照组相比,当1,2,4-TCB 浓度大于5 mg/L 时,各染毒组细胞 尾长、尾部DNA 百分率均极显著升高,即1,2,4-TCB 染毒引起了肝细胞DNA 的严重断裂;随着1,2,4-TCB 浓 度的增加,DNA 损伤程度加剧,细胞尾长、尾部DNA 百分率及尾距与1,2,4-TCB 染毒浓度呈明显的剂量- 效应 关系。结果表明,水体中残留的1,2,4-TCB 可导致斑马鱼肝细胞DNA 损伤。
英文摘要:
      In order to explore the DNA damage in cells induced by 1,2,4-TCB,hepatocyte cells of zebrafish cultured in vitro were exposed to different concentrations of 1,2,4-TCB(0,1,5,10 mg/L)for 2 h. Then,the comet assay was applied to measure the DNA damage. Results showed that tail length,tail DNA rate of hepatocyte cells both significantly increased when treated with more than 5 mg/L 1,2,4-TCB compared with the control group. Meanwhile,the DNA damage increased gradually with the increase of 1,2,4-TCB concentration. There was an obvious dose relationship between 1,2,4-TCB concentration and DNA damage(tail length,tail DNA rate,tail moment). It was concluded that 1, 2,4-TCB could induce DNA damage in hepatocyte cells of zebrafish
