本文利用１９８８年在一组青年人群食管炎患病率与有关因素调查基础上，随机观察了３８例食管上皮的３Ｈ－ＴｄＲ标记，将食管上皮细胞标记指数（ＬＩ）分别与性别、年龄、家族史、吸烟、正常食管与食管炎及饮食中动物蛋白和水果蔬菜的数量等方面进行了相关性研究，结果显示除食用动物蛋白外，ＬＩ与上述因素均呈显著性相关。食管上皮细胞的３Ｈ－ＴｄＲ的标记方法，在进一步证实食管炎与食管癌关系的研究方面，是一个可靠的生物学中间终末指标之一。 Based on the investigation of the prevalence and related factors of esophagitis in a group of young people in 1988, the 3H-TdR markers of 38 cases of esophageal epithelium were randomly observed. The esophageal epithelial cell labeling index (LI) was correlated with gender, age, and family respectively. History, smoking, normal esophagus and esophagitis, and dietary animal protein, fruits and vegetables were investigated. The results showed that in addition to animal protein, LI was significantly associated with the above factors. The 3H-TdR labeling method of esophageal epithelial cells is one of the reliable biological intermediate terminal indicators in the further study of the relationship between esophagitis and esophageal cancer.
