Lipid analysis of lavage samples from the equine guttural pouch (auditory tube diverticulum)

Baptiste, K.E. and Cake, M.H. (1994) Lipid analysis of lavage samples from the equine guttural pouch (auditory tube diverticulum). Annals of Otology, Rhinology and Laryngology, 103 (51). pp. 383-388.

Abstract

The guttural pouch is a large, air-filled diverticulum of the auditory tube, present in the horse and other species. Lipid analysis of saline lavage from the equine guttural pouch has demonstrated the presence of phospholipids and neutral lipids in amounts that are variable but consistently greater than in any other species described. A stain specific for choline-containing phospholipids has demonstrated the presence of phospholipid-containing vesicles only within the cells of subepithelial, seromucoidlike glands, suggesting that these cells incorporate phospholipids in their secretions. The functional significance of surface-active agents in the guttural pouch may be different from that proposed for other species because of the unique anatomical design and the different proposed functions of the guttural pouch.
