From: A comparative study on the anti-inflammatory effects of single oral doses of naproxen and its hydrogen sulfide (H2S)-releasing derivative ATB-346 in rats with carrageenan-induced synovitis

Effects of treatment with single oral doses of naproxen or ATB-346 on gait score secondary to CGN-induced synovitis in rats. CGN-injected animals were orally pre-treated with naproxen (at 0.3, 1, 3 and 10 mg/kg; n = 8), equimolar ATB-346 doses (0.48, 1.6, 4.8 and 16 mg/kg; n = 8) or vehicle (1 ml/kg; n = 8). A separate control group (Sham - S) received only an i.art. injection of saline injection (n = 5). Panels A and B illustrate the walking behaviours evaluated 3 and 5 h after CGN injection, respectively, which were scored on a scale from 0 (normal) to 3 (total joint immobility). Data are presented as scatter plots with the median values for each experimental group, and differences among the groups were non-parametrically analysed by the Kruskal-Wallis test followed by the Dunn’s test for multiple comparisons. *P < 0.05, **P < 0.01 and ***P < 0.001 vs. the vehicle-treated (V); ##P < 0.01 and ###P < 0.001 vs. the corresponding S group.
