Fig. 4

Interleukin-1β (IL-1β) and tumor necrosis factor α (TNF-α) concentrations in the synovial fluid of middle carpal joints (MCJ) and tarsocrural joints (TCJ) following IL-1β-induced synovitis or intra-articular lavage. IL-1β remained unchanged following synovitis induction (a) or intra-articular lavage (b). TNF-α was increased from baseline and was greater in synovitis MCJ as compared to contralateral MCJ at 6 h post-synovitis induction (c). TNF-α was unchanged from baseline following lavage with no differences from contralateral TCJ (d). An asterisk indicates a difference from baseline, and a triangle indicates a difference from the contralateral limb at the same time point. Graphed values are marginal means +/− SEM
