Description
Summary:Glycosaminoglycan content and cell density of articular cartilage have been studied quantitatively in the adult rabbit in experimental lipoarthrosis. On the fourth day after injection of non-radioactive or tritium-labelled glyceryl trioleate into the synovial cavity of the knee joint, femoral condylar cartilage shows no change in cellularity. There is a 35% loss of chondroitin sulphate from the matrix, but little change in keratansulphate. The results are not affected by the presence or absence of radioactive isotope in the lipid: possible mechanisms accounting for glycosaminoglycan loss are discussed.
