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 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 کاملThe Bovine Cornea Opacity and Permeability Test
An in vitro test for the development of corneal opacity in response ocular irritants was first proposed by Muir (1984). This test required the clamping of a bovine cornea between two chambers filled with physiologic saline and measuring the transmittance of white light through the cornea using the voltage output of a photocell. This was followed by exposure of the epithelial surface of the corn...
متن کاملInteractions between bovine cornea proteoglycans and collagen.
Two types of proteoglycan subunits were obtained from bovine cornea, the first mainly composed of proteochondroitin sulphate and the second of proteokeratan sulphate. These two fractions can be obtained from the tissue as an aggregate, and are able to recombine each other after separation, to re-form the original structure. In order to investigate collagen-proteoglycan interactions, type-I coll...
