摘　　要：目的揭示人胎儿小肠上皮内淋巴细胞分布及其数量变化规律;方法采用HE染色的方法,观察62例10～38周人胎儿小肠上皮内淋巴细胞的分布并对其进行计数;结果绝大部分上皮内淋巴细胞分布在上皮细胞基底部,位于上皮细胞核下方,只有少数位于或超过上皮细胞核水平;上皮内淋巴细胞计数随胚胎发育而逐渐增多,从十二指肠到回肠,其数量逐渐减少。在35-38周胎龄时,十二指肠、空肠、回肠每100个绒毛上皮细胞范围内淋巴细胞的平均值分别达10.6、9.3和8.9;结论绝大多数上皮内淋巴细胞分布在上皮细胞核下方,其数量随胚胎发育而逐渐增多,从十二指肠到回肠,其数量逐渐减少。Objective To discover the law of dis-tribution and quantitative change of intraepithelial lymphocytes(IEL)in small intestine of human fetus.Methods Counts and distribution of IEL in small intestine of62human fetuses aged from10to38weeks were investigated with HE stain method.Results The great majority of IEL were located in the basal region of the epithelium,below the level of the epithelial cell nuclei,with a few at or above the level of the nuclei.IEL counts increased devel-opmentally with the increase of fetal age,and de-creased locationally from duodenum to ileum.At 35～38weeks of gestation,IEL counts,from duode-num,jejunum to ileum were,on average,10.6,9.3and8.9per100epithelial cells respectively.Conclu-sion The great majority of IEL in small intestine of human fetus were located below the level of the epithelial cell nuclei,IEL counts increased develop-mentally with the increase of fetal age,and de-creased locationally from duodenum to ileum.
