[Collagen from human joint cartilage in deforming arthritis].

Type II collagen of human cartilage has been comparatively studied in norm and at deforming arthrosis. Collagen preparations are characterized by aminoacid composition and electrophoretic mobility in polyacrylamide gel. It is supposed that at deforming arthrosis the degenerative-dystrophic processes in the articular cartilage of man are caused by appearance of procollagen.
