摘要
对广西某肝癌高发区饮水类型和主食口粮不同的各组人群共122例进行了SCE检测.结果表明:长期饮用塘水、主食玉米占口粮50%以上人群与长期饮用自来水、主食大米人群的SCE频率相比较,均有显著性差异.提示:SCE频率升高可能与长期摄入黄曲霉毒素B_1和饮用塘水有关.
The sister-chromatid exchanges (SCEs) in the peripheral lymphocytes of 122 persons who drank the different types of water and food in a high incidence area of liver cancer were analyzed.The results showed that the frequency of SCE in the persons who drank pond water and eating a diet contain-ing corn more than 50% differred significantly from the persons who drank clean water and ate rice for a long time.The results suggested that the increase in SCE rates might be related to the prolonged in take of AFB_1 and drinking pond water.
