The mucopolysaccharides of bovine cornea.
The mucopolysaccharides isolated from various mesodermal tissues have, in several instances, been shown to consist of complex mixtures, and not of single compounds as was believed formerly. In view of the rather contradictory findings reported in the literature, it was thought advisable to reinvestigate the mucopolysaccharide fractions of the cornea. In this paper, the separation of three disti...
متن کاملBiosynthesis of Glycosaminoglycans during Cornea 1 Development
Glycosaminoglycan biosynthesis was studied in developing chick corneas, with particular attention paid to keratan sulfate I, the major glycosaminoglycan of this tissue. This polysaccharide is unique to the cornea and may be required for the development and maintenance of cornea1 transparency. Corneas from 5. to 20-day chick embryos were labeled in uitro with D[6-3H]glucosamine and H2”S0,, and t...
متن کاملEnzymic sulfation of corneal mucopolysaccharides by beef cornea epithelial extract.
On an anatomical basis, cornea may be divided into three major parts: the fibrous stroma, the overlying epithelium, and endothelium. Epithelial and endothelial cells contribute approximately 20% of the total wet weight of beef cornea, and their integrity is essential for stromal maintenance (1). Of the three major parts of cornea, epithelial cells have the highest oxygen consumption that can be...

متن کاملAnalysis of glycosaminoglycans in rabbit cornea after excimer laser keratectomy.
BACKGROUND/AIMS The biochemical basis for the development of subepithelial opacity of the cornea after excimer laser keratectomy has yet to be fully defined. The aim of this study was to evaluate the alterations of glycosaminoglycans (GAGs) after excimer laser keratectomy. METHODS Rabbit corneas were harvested on days 5, 10, 20, and 30 after excimer laser photoablation. The amount of main dis...
