摘要: 近年来,微量元素与肿瘤的关系日益为人们所重视。据报导,美国肠癌高发与环境中缺硒有关;北威尔斯胃癌高发与土壤中缺铜、富锌有关;非洲肝癌高发区,土酒受、锌钴污染,肝癌组织里锌、钴增加而钼减少。因此,探素环境因素与区域性肿瘤高发之间的联系,已成为医学与地学工作者共同关注的课题。

Abstract: In this paper. We have analysed the trace elementr Mo, Cu, Zn of the geographical environments in the Yengtre River delta and adjacent arean in onder to investigate the pathogeny of lives cancer. The primany nerults have been of abtained as below: 1. The disticbution of this Clisease has obvious distvict Characteristis.In the areas of high incedencc, the Content of molybdenum in the water and soil is higher, while in the staple food is lower. Thus it dan be seen that the Content of molybdenum entering human body is lower. The intake of molybdenum scene to have negative relation with the mortality of liver Cancer. 2. The absorption of molybdenum in human body decreases, by excess Cu and SO4, entering local masses through food Chain. It leads to low Content of molybdenum in human body. 3. There phenomena Can checrcase enzywe activity,and form the damage of liver function. On other hand. it aid to synthesize nitrosamine, and to pollute from aflatoxin in the food. These lead to enhance the carcinogenesis of nctro-samine and aflatoxin.
