Experimental study of therapeutic effects on osteoarthritis with sodium hyaluronate of different molecular weight

  • Received Date: 2009-07-07

  • Objective To study the therapeutic effects of sodium hyaluronate injection of different molecular weight(MW: 800~1500 kDa vs.1500~2500 kDa) on osteoarthritis. Methods Two kinds of osteoarthritis models were induced in rabbit’s knee joints: long-term immobilization experiment,and intra-articular injection of papain.Pathological study,analgesic effect experiment and capillary permeability experiment were carried out to observe the effects of treatment with intra-articular injection of sodium hyaluronate. Results Both of the two kinds of sodium hyaluronate injection of different molecular weight have the ability to resist the pathological changes of cartilage and synovial.They all show significant analgesic effect and inhibit capillary permeability.Furthermore,greater improvement in osteoarthritis models induced by intra-articular injection of papain was achieved by administration of sodium hyaluronate of relatively low molecular weight(MW: 800~1500 kDa). Conclusion Sodium hyaluronate of different molecular weight all could improve the outcomes of osteoarthritis.Our findings suggest that sodium hyaluronate treatment of osteoarthritis is a safe,effective therapeutic option,and low molecular weight sodium hyaluronate may have better performance in improving the pathological changes of cartilage and synovial.

Abstract: Objective To study the therapeutic effects of sodium hyaluronate injection of different molecular weight(MW: 800~1500 kDa vs.1500~2500 kDa) on osteoarthritis. Methods Two kinds of osteoarthritis models were induced in rabbit’s knee joints: long-term immobilization experiment,and intra-articular injection of papain.Pathological study,analgesic effect experiment and capillary permeability experiment were carried out to observe the effects of treatment with intra-articular injection of sodium hyaluronate. Results Both of the two kinds of sodium hyaluronate injection of different molecular weight have the ability to resist the pathological changes of cartilage and synovial.They all show significant analgesic effect and inhibit capillary permeability.Furthermore,greater improvement in osteoarthritis models induced by intra-articular injection of papain was achieved by administration of sodium hyaluronate of relatively low molecular weight(MW: 800~1500 kDa). Conclusion Sodium hyaluronate of different molecular weight all could improve the outcomes of osteoarthritis.Our findings suggest that sodium hyaluronate treatment of osteoarthritis is a safe,effective therapeutic option,and low molecular weight sodium hyaluronate may have better performance in improving the pathological changes of cartilage and synovial.
