Following injection of chymopapain into a single knee joint in rabbits, serum keratan sulfate levels rose sharply and remained elevated for at least 48 hours before returning to preinjection levels. These changes were accompanied by depletion of proteoglycans from articular cartilage in the injected joint. We conclude that serum keratan sulfate levels rise predictably following acute loss of proteoglycan from a single joint.

D007632	Keratan Sulfate	A sulfated mucopolysaccharide initially isolated from bovine cornea. At least two types are known. Type I, found mostly in the cornea, contains D-galactose and D-glucosamine-6-O-sulfate as the repeating unit; type II, found in skeletal tissues, contains D-galactose and D-galactosamine-6-O-sulfate as the repeating unit.

D002358	Cartilage, Articular	A protective layer of firm, flexible cartilage over the articulating ends of bones. It provides a smooth surface for joint movement, protecting the ends of long bones from wear at points of contact.	Articular Cartilage,Articular Cartilages,Cartilages, Articular
D002917	Chymopapain	A cysteine endopeptidase isolated from papaya latex. Preferential cleavage at glutamic and aspartic acid residues. EC 3.4.22.6.	Chemolase,Chymodiactin,Chymopapain A,Chymopapain B,Discase
D006025	Glycosaminoglycans	Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
