ABSTRACT

Structure and distribution of the mucosal immunological tissue and cells in reproductive duct of female two-humped camels were observed with microscope and electro-microscope. Intraepithelial lymphocytes (IEL) were scattered extensively in the mucosal epithelium and gland epithelium of the oviduct, uterus and vagina, and lymphocytes infiltration in the mucous epithelium of the posterior segment of the cervix, uteri and the anterior segment of the vagina was found evenly. Variable numbers of lamina propria lymphocytes (LPL), plasma cells, macrophages and neutrophilic granulocytes were distributed in lamina propria along the duct from fimbriae tubea to the vagina. The special eosinophil cells appeared in groups in the lymph nodule arising in lamina propria of the uterus, which were found to be dendritic cells (DC). There were also some neutrophilic granulocytes in the epithelium of mucosa and gland and inside the glandular cavity of cervix uteri. Mast cells in groups were observed in deeper lamina propria and upper muscular layer of the uterus but they were not found in that of the pregnant camels. The multitudinous plica and glands of the mucosa in reproductive duct could enormously increase the surface area of the epithelium and then increased the number of mucosal immunological tissue and cell. The results suggested that the reproductive duct of the female camel may possess an active mucosal immune activity.
