[Lipid peroxidation and proteinase inhibitors in experimental osteoarticular tuberculosis].
Changes in lipid peroxidation parameters (LP), antioxidant system and proteinase inhibitors were studied at different evolutionary stages of experimental osteoarticular tuberculosis in 30 rabbits. All stages of the process were characterized by LP activation which in animals of all groups (except rabbits having the acute stage of arthritis) is accompanied by compensatory increase of superoxide dismutase and ceruloplasmin activity. Deficiency of superoxide dismutase found in the acute stage of arthritis with a growth of LP activity shows its inadequate production at a given stage of articular inflammation. Decrease in alpha 1-proteinase inhibitor activity at the stage of osteitis with reactive synovitis can be caused by the influence of LP products. The importance of this mechanism in the inhibition of alpha 1-proteinase inhibitor, together with reduction in its production at the acute stage of arthritis, cannot be ignored. The results obtained make it possible to recommend further study of the perspectives of antioxidants use in osteoarticular tuberculosis.
