摘要: 目的:为研究油烟凝聚物与肿瘤发生的潜在关系及大蒜油的防护作用。方法:用油烟凝聚物和大蒜油分别或同时处理V79细胞,利用免疫细胞化学方法检测V79细胞中p53 、p21ras蛋白的表达情况。结果:与对照组相比,油烟凝聚物处理组p53 、p21ras蛋白表达明显升高( P < 0. 01) ,且有剂量———效应关系;与对照组相比,50μl/ ml 大蒜油处理组降低油烟凝聚物诱发V79细胞p53 、p21ras蛋白表达水平( P < 0. 05 或P < 0. 01) 。结论:油烟凝聚物有诱变作用,大蒜油可防护油烟凝聚物的诱变作用。

Abstract: Purpose : This paper studies the relationships between Heated Cooking Oil Vapors (HCOV) and Allium Sativum Oil (ASO) in mutagenesis. Methods : we detected p53 and p21ras protein expression in the V79 cells treated by HCOV and ASO with immunocytochemical techneques. Results : The result s showed that the p53 and p21ras protein expression was significantly increased in HCOV groups compared with the cont rol group ( P < 0.01) , and a dose2dependent relationship was observed , while the ASO(50μg/ ml) could decreased the p53 and p21ras protein expression in the V79 cells t reated by HCOV compared with the cont rol group ( P < 0. 05 or P < 0.01) . Conclusion : The result s indicated that the ASO could prevent f rom mutagenic activity of the HCOV.
