Abstract
Sera and synovial fluids from patients with rheumatoid arthritis (RA), and with osteoarthritis (OA) as a control, were investigated for lipid peroxide level, .beta.-glucuronidase activity, acid phosphatase activity and .alpha.-tocopherol level. Lipid peroxide level, .beta.-glucuronidase activity and acid phosphatase activity increased in synovial fluids of RA patients, suggesting that the generation of lipid peroxide in the rheumatoid joints plays a role in the liberation of lysosomal enzymes into the synovial fluids. Significant correlation was demonstrated between lipid peroxide and .beta.-glucuronidase and/or acid phosphatase in synovial fluids from RA patients. Increased .alpha.-tocopherol level in RA synovial fluids might be explained by the increased vascular permeability in the rheumatoid joints since there was no difference in .alpha.-tocopherol level between RA and OA sera. Apparently the increase of lipid peroxide in the synovial fluids in the rheumatoid joints was important in lysosomal instability of synovial lining cells or influxed polymorphonuclear leukocytes.
