## Abstract Synovial fluids from 31 patients with seropositive rheumatoid arthritis (RA) and 23 patients with seronegative RA had significantly increased levels of breakdown products of C3, C4, and properdin factor B when compared to patients with osteoarthritis (OA) (__P__ < 0.01). The same patien

Soluble interleukin-2 receptor (sll-2R) levels were quantitated in the seum and synovial fluid (SF) of patients with rheumatoid arthritis (RA) and degenerative joint disease (DJD). A sandwich immunoassay, employing two monoclonal antiodies against distinct epitopes on the lL-2R, was utilized for mea
To determine whether complement turnover in synovial fluids of patients with rheumatoid arthritis (RA) reflects activation by the classical or alternative pathway, we used novel immunoassays to measure products of complement activation (the membrane attack complex SC5b-9 and the cleavage fragments B
