黄曲霉毒素B_1(AFB_1)能诱发出所有实验动物的肝癌,是已知化学致件癌物最强的一种。为进一步探索AFB_1与肝癌的关系,近三年来国内、外学者进行了大量的研究。流行病学 1.AFB_1污染与肝癌发病率地理分布一致:Hsidh分析表明,中国和某些非洲国家肝癌发病常与AFB_1关系似乎比乙型肝炎更密切。汪耀斌指出:(1)我国90％以上肝癌高发区位于东南沿海狭长地区,提示癌分布与所处的地理环境密切相
Aflatoxin B_1 (AFB_1) can induce liver cancer in all experimental animals, and is the most powerful type of known cancerous cancer. To further explore the relationship between AFB_1 and liver cancer, domestic and foreign scholars have conducted a lot of research in the past three years. Epidemiology 1. AFB_1 pollution and the geographical distribution of liver cancer incidence consistent: Hsidh analysis shows that the incidence of liver cancer in China and some African countries often seem more closely related to AFB_1 than hepatitis B. Wang Yaobin pointed out: (1) More than 90% of the high-incidence areas of liver cancer in China are located in narrow and long areas along the southeast coast, suggesting that cancer distribution is closely related to the geographical environment in which it is located.
