Abstract:
Lectin histochemistry combined with glycosidase digestion was used to investigate the presence of glucidic residues and identify the terminal residues and their acceptor sugars in these glands. Quantitative evaluation of lectin-positive sites was made by histophotometrical scanning. Lectin histochemistry demonstrated that the anteromedial portion contains disaccharides sialic acid-D-Gal, sialic acid-D-GalNAc and Fuc-D-Gal, and that the anterolateral portion contains the terminal dimer sialic acid-D-Gal only. These findings have hypothetical significance in terms of the known functions of chicken anterior lingual glands.
