  • Title: Biochemistry of glycosaminoglycans in the skin and oral mucosa of the rat.
    Author: Pedlar J.
    Journal: Arch Oral Biol; 1984; 29(8):591-7. PubMed ID: 6591892.
    Abstract:
    Glycosaminoglycans (GAG) were extracted by digestion with papain followed by ultrafiltration and separated by cellulose-acetate electrophoresis and by chromatography of their cetyl-pyridinium complexes on cellulose microcolumns. The uronic-acid content of the tissues ranged from 0.8 to 2.4 mg/g of dry defatted tissue. Hyaluronic acid and dermatan sulphate were found in all tissues with chondroitin-4-sulphate also in skin, palatal mucosa and gingiva. There was 3-fold more hyaluronic acid in palatal mucosa than in any other tissue; it was concentrated in the antemolar rugae. A substance of presumptive salivary origin staining with alcian blue was found in cheek and floor of mouth mucosa. It migrated differently from reference GAG by electrophoresis and was not degraded by testicular hyaluronidase.
