| Popis: | Studies were made on the distribution of lymphoid tissues and immunoglobulin (Ig: IgA, IgG and IgM)-containing cells (cIg: cIgA, cIgG and cIgM) and the localization of immunoglobulins (Igs) in the oviducal walls of laying hens. Lymphocyte accumulations were occasionally observed, located mainly in the middle infundibulum and in the regions from the isthmus to the vagina. The number of cIgG significantly predominated over that of cIgA or cIgM in the mucosal connective tissue of the magnum and the isthmus. In contrast, in the regions other than the magnum and the isthmus, these three types of cIg were fewer in number. Igs were localized in some superficial epithelial cells (SECs) and glandular cells (GlCs) of the oviduct. Many IgG-containing SECs were found in the infundibulum, the isthmus, and the cranial and major uterus. IgA- or IgM-containing SECs were rare throughout the oviduct. Three types of Ig-containing GlCs were numerously found in the magnum, though lymphocyte accumulations were scarce there. In the isthmus, many IgG-containing GlCs were found, while IgA- or IgM-containing GlCs were rarely observed. Ig-containing GlCs in the magnum were considerably decreased in number after the egg passage. The results suggest that the maternal Igs are transferred to the egg mainly through GlCs in the magnum of the chicken oviduct, and that the oviducal lymphoid tissues have little relationship to the passive immunity. |
