Figure 6: Nitrite levels in synovial exudates of zymosan-induced TMJ arthritis. Zymosan was injected i.art. and the NO release in exudates (as / ) was measured 6 h after zymosan. Sham animals received only saline i.art. Injection of saline into the joints did not increase NO release throughout the experiment. Data are expressed as means ± SEM ( ). versus Sham (ANOVA, Bonferroni).
