Histological and histochemical aspects of the mucosa of the nasal conchae in the zebu (Bos indicus).
In various respiratory areas of the mucosa of the nasal conchae of the zebu (Bos indicus) there is a quantitative variation of goblet cells. The glands are tubular or tubulo-alveolar, having morphologically serous and mucous cells. The excretory ducts are formed by non-secreting cells. The goblet cells and glands elaborate a glycoprotein. The carbohydrate portion is probably an association of neutral mucopolysaccharides, sulphated acid mucopolysacchardies and sialic acid and its proteic portion contains alpha-amino radicals. Tryptophan- and tyrosine-rich proteins are demonstrated only in the glandular secretion.
