title: [Effects of ulinastatin on experimental arthritis].
abstract: Effects of the urinary enzyme inhibitor ulinastatin on experimental arthritis were investigated. Ulinastatin at the dose of 30,000 units/kg/day, i.v., significantly restored the swelling of hind paw, inflammatory score and bone damage in adjuvant arthritic rats. Intraarticular administration of ulinastatin at 3000 units/site x 3, significantly suppressed the articular swelling and the elevated inflammatory parameters in the synovial fluid of carrageenin-induced arthritic rabbits. Moreover, ulinastatin at the dose of 50000 units/kg/day, i.v., significantly prevented the elevation of serum rheumatoid factor and articular lesions in MRL/l mice. In addition, ulinastatin significantly inhibited human granulocyte elastase and cathepsin G. These findings indicate that ulinastatin may be a useful therapeutic agent for arthritis.
