烹调烟雾冷凝物的DNA损伤和细胞转化作用研究
DNA Damage and Cell Transforming Activity Caused by Cooking Fume Condensates
【摘要】 为全面评价烹调烟雾的危害,收集居民家用脱排油烟机中的烹调烟雾冷凝物,经干燥脱水后,应用人外周血淋巴细胞非程序DNA合成试验(UDS)及BALB/c3T3细胞体外培养系统,检测居民厨房中烹调烟雾冷凝物的DNA损伤作用及对BALB/c3T3细胞的毒性与转化作用。结果表明受试物在加S9和不加S9时,均能提高CPM值,DNA放射比活性R值均随测试浓度的增加而升高;受试物对BALB细胞具有明显的细胞毒性与转化作用,其转化率随检测浓度升高而升高。提示烹调烟雾冷凝物具有DNA损伤和细胞转化作用,且具有一定的剂量效应关系。
【Abstract】 To assess the hazardous effect of cooking fume comprehensively,cooking fume condensates were collected from many families that used rapseed oil as cooking oilsUnscheduled DNA synthesis(UDS) test and the cell transformation assay were applied to detect the DNA damage and the cell transforming activity of cooking fume condensatesThe results showed that 1)the condensates of cooking fumes could increase the CPM of human peripheral blood lymphocytes apparently with and without S9,and there was a significant doseeffect relationship between the CPM and consistency of condensates 2)condensates of cooking fumes ould induce morphological transformation in BALB/c3T3 A3111 cells,and there was a doseeffect relationship in the cell transformation frequencyIt indicated that condensates of cooking fumes ould cause DNA damage and cell transforming activity,and doseeffect relationship in certain extent was induced cooking fumes might possess potential carcinogenic hazards to the exposures
