title: Gene expressions of antiinflammatory mediators in THR retrieved interfacial membranes.
abstract: We investigated gene expression of antiinflammatory mediators in the interfacial membranes retrieved at hip revision arthroplasty using reverse transcription-polymerase chain reaction (RT-PCR). Levels of RT-PCR products were compared with those of synovial tissue from patients with osteoarthrosis or rheumatoid arthritis. Antiinflammatory mediators such as type II interleukin (IL)-1 receptor, IL-4, IL-10, IL-1 receptor antagonist, and transforming growth factor-beta 1 (TGF-beta 1) were expressed in the interfacial membrane. In interfacial tissue, the level of IL-10 was lower, but that of the IL-1 receptor antagonist higher than in diseased synovial tissue.
