Lectin binding histochemistry was performed on the olfactory system of Physignathus lesueurii to investigate the distribution and density of defined carbohydrate terminals on the cell-surface glycoproteins of the olfactory and vomeronasal receptor cells and their terminals in the olfactory bulbs. The lectin staining patterns indicate that the vomeronasal and olfactory receptor cells are characterized by glycoconjugates containing alpha-D-galactose and N-acetyl-D-glucosamine terminal residues. The presence of specific glycoproteins, whose terminal sugars are detected by lectin binding, might be related to the chemoreception and transduction of the odorous message into a nervous signal or to the histogenesis and development of the olfactory system. The olfactory and vomeronasal receptor cells are vertebrate neurons that undergo a continual cycle of proliferation not only during development but also in mature animals.
对 Lesueur 鬃狮蜥的嗅觉系统进行凝集素结合组织化学分析，以研究嗅觉和犁鼻器受体细胞及其在嗅球中的终末细胞表面糖蛋白上特定碳水化合物末端的分布和密度。凝集素染色模式表明，犁鼻器和嗅觉受体细胞的特征是含有α-D-半乳糖和N-乙酰-D-葡萄糖胺末端残基的糖缀合物。其末端糖通过凝集素结合检测到的特定糖蛋白的存在，可能与化学感受以及将气味信息转化为神经信号有关，或者与嗅觉系统的组织发生和发育有关。嗅觉和犁鼻器受体细胞是脊椎动物神经元，不仅在发育过程中，而且在成熟动物中都经历持续的增殖周期。
