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.
对产蛋母鸡输卵管壁中淋巴组织和含免疫球蛋白（Ig：IgA、IgG和IgM）细胞（cIg：cIgA、cIgG和cIgM）的分布以及免疫球蛋白（Igs）的定位进行了研究。偶尔观察到淋巴细胞聚集，主要位于漏斗中部以及从峡部到阴道的区域。在膨大部和峡部的黏膜结缔组织中，cIgG的数量显著多于cIgA或cIgM。相比之下，在膨大部和峡部以外的区域，这三种类型的cIg数量较少。Igs定位于输卵管的一些表层上皮细胞（SEC）和腺细胞（GlC）中。在漏斗部、峡部以及子宫头部和主要子宫中发现了许多含IgG的SEC。在整个输卵管中，含IgA或IgM的SEC很少见。在膨大部发现了大量三种类型的含Ig的GlC，尽管那里淋巴细胞聚集很少。在峡部，发现了许多含IgG的GlC，而含IgA或IgM的GlC很少被观察到。产蛋后，膨大部中含Ig的GlC数量大幅减少。结果表明，母体Igs主要通过鸡输卵管膨大部的GlC转移到蛋中，并且输卵管淋巴组织与被动免疫关系不大。
