胃癌高发区居民血清学检查动态观察及其与低发区者对比

CHANGE OF DIETARY HABITS IN INHABITANCES AND SERUM CAROTENOIDS LEVEIS IN HIGH RISK AREA OF STOMACH CANCER

1984年—1989年在胃癌高、低发区自然人群中35岁以上居民,用HPLC及免疫扩散法,分期做了血清学检测273人,结果表明胃癌高发区居民血清中胡萝卜素成分,特别是B-Carotene的含量低于胃癌低发区居民,当改变高发区居民饮食品种及习惯之后则该成分逐年上升并可达到低发区居民水平。提示在胃癌高发区改变居民长年形成的不良饮食习惯是控制胃癌对策的重要措施。

Serum carotenoids concentration in inhabitance over 35 aged in high andlow risk area of stomach cancer were determined by HPLC or immunodiffusion in 1984～1989 separately. The result of examination showed that the serumconcentration of carotenoids especially B-carotene in inhabitance of high riskarea of stomach cancer is lower than that one in low risk area of stomachcancer. However the serum carotene level increased gradually when the inhabi-tance changed their habit of food consumption in high risk area of stomachcancer and it seems probable that food change by inhabitance in high risk area of stomach cancer can be provent from carcinoma of stomach.
