过去在肝癌发病水平不同地区多次的对比调查,均说明肝癌高发与主粮的玉米比重、黄曲霉毒素污染、饮用圹水等因素有关,而自然人群中HBsAg阳性率与肝癌的关系,则有时呈平行关系,有时又不平行。考虑到HBsAg检查方法灵敏性的影响。这次改用较灵敏的反向间接血凝法及对流免疫电泳法同时检测HBsAg,并调查平均黄曲霉毒素摄入量。在扶绥县 In the past in the incidence of liver cancer many times in different areas of the comparative survey all indicate that the high incidence of liver cancer and the main staple of the proportion of corn, aflatoxin contamination, drinking water and other factors, and the natural population of HBsAg positive rate and liver cancer, sometimes Parallel relationship, sometimes not parallel. Consider the impact of the sensitivity of the HBsAg assay. This time switch to more sensitive reverse indirect hemagglutination and convective immuno-electrophoresis simultaneous detection of HBsAg and investigate the average aflatoxin intake. In Fusui County
