A type of water-soluble carboxymethyl chitosan (O--CMC), with 76% degree of substitution determined by conductivity method, was prepared by using chloroacetic acid to react with C6-OH of chitosan. The solubility of O--CMC was characterized also. Animal experiment in rabbits showed that O--CMC could lubricate arthron, inhibit proliferation of fibroblast cells on rabbits' knee joints, benefit the process of repairing pathologic articular cartilage, and produce good therapeutic effect on rheumatoid arthritis.
