Abstract:
The aim of this study was to investigate the carbohydrate composition of mucosubstances in the equine guttural pouches using conventional histochemical tests in conjunction with glycolytic digestion to degrade different classes of glycosoaminoglycans. In the goblet cells, the mucopolysaccharides contained chondroitin sulfate B, heparin, heparan sulfate and sialic acid residues. The acinar cells also expressed these substances (except for heparin), whereas the ductal cells produced chondroitin sulfate B and sialic acid. Neutral sugars were also found in each cell type. The diversity of the glycocomponents found in the auditory tube suggests that they may have important functional roles. Indeed, the glycosoaminoglycans provide a hydrophilic environment that prevents dehydration and desiccation of the guttural membranes during air passage. Additionally, these glycomolecules may be involved in the pathogenesis of some bacterial disease in horses, such as equine strangles.
