摘要 本文对饲喂莫能霉素的兔,无菌兔和普通兔,饲喂磷酸左咪唑及感染柔嫩爱美尔球虫的鸡,感染球虫的雏鸭以及雏鸡新城疫消化道免疫后肠道上皮间淋巴细胞的形态、功能做了研究。结果表明,肠上皮间淋巴细胞是一种免疫活性细胞,其数目与肠腔中抗原的种类和数量有关。肠上皮间淋巴细胞主要位于上皮细胞核的上方、核间及核下方,形态不一。其分布以十二指肠和盲肠扁桃体较多,空肠低于十二指肠,回肠又低于空肠,直肠最少。肠上皮间淋巴细胞的数量与粘膜固有层的淋巴细胞数量呈正相关。本文还对上皮间淋巴细胞的功能、性质及迁移进行了讨论。 This experiment studied respectively the morphology and function of intcrepithelial lymphocytes ( IEL ) in the intestine of rabbits that were fed monensin; bacterium free rabbits; commercial rabbits; chicks that were fed levomisole phosphate and infected Eimeria tenella; ducklings that were infected coccidiae; chickens that were immunized with Newcastle disease vaccine by alimentary tract, The results show that IEL is an immune competent cell, its number is related with kinds and quantities of antigen in intestine tract. IEL is at the level of supranucle-ar, nuclear and subnuclear. Its appearences are various. The great majority of IEL are located in the duodenum and caecal tonsilsa;the number in the jejunum is lower than that in the duodenum; the number in the ileum is lower than that in the jejunum; the number in the rectum is lower than that in the ileum. The number of IEL is in direct proportion to the number of lymphocyte in the mucosa. In addition, the function, character and migration of IEL. were also discussed.
