title: Histochemistry of complex carbohydrates in the skin of the pig snout, with special reference to eccrine glands.
abstract: The histochemistry of carbohydrates has been studied in the skin of the pig snout with selected methods of light microscopy including peroxidase-labelled lectin-diaminobenzidine (PO-LT-DAB) procedures. In the snout skin the dark secretory cells and the luminal secretion of the eccrine glands contained considerable amounts of neutral glycoproteins, but only a very small amount of acidic ones. It was possible to demonstrate glycogen in the secretory cells of these glands. The other skin structures of the snout also showed positive reactions for complex carbohydrates. Most remarkable were stronger reactions of intercellular substances among the spinosum cells, particularly following the PO-LT-DAB procedures, which demonstrated such saccharide residues as beta-D-galactose and N-acetyl-D-glucosamine.
