肝癌高发区不同饮食类型人群的外周血淋巴细胞染色体畸变分析

CHROMOSOME ABERRATION ANALYSIS OF HUMAN PERIPHERAL BLOOD LYMPHOCYTES IN INHABITANTS LIVING ON DIFFERENT TYPES OF FOOD AND WATER IN HIGH INCIDENCE AREA OF LIVER CANCER

用染色体畸变分析技术检测肝癌高发区112例不同饮食类型居民的外周血。发现长期主食玉米(AFB_1污染严重)、饮用污染塘水者其淋巴细胞染色体畸变率显著高于主食大米、饮用河水、自来水者。研究结果提示:该地区居民的肝癌高发病率与长期的AFB_1高摄入及饮用污染的塘水有关。

Chromosome aberration analysis technique was used to examine the peripheral blood lymphocytes of 112 inhabitants living on different types of food and water in the high incidence area of liver cancer(Fusui county,Guangxi).The results showed that the chromosome aberration rates(CAR)of these inhabitants drinking for a long time pond water and eating corn heavily contaminated by AFB_1 were greater than those drinking clean water and eating rice.These results suggested that the hight incidence of liver cancer in Fusui might be related to the prolonged taking of AFB,and pond water.
