Clearance of proteoglycan from joint cavities. [PDF]
Annals of the Rheumatic Diseases, 1987 The rate of loss from the synovial cavity of proteoglycan subunit, a major constituent of cartilage, has been measured in rabbits with and without experimental arthritis. The effect of aggregation between proteoglycan and hyaluronic acid upon the rate of elimination has also been investigated.
