Effect of rosiglitazone and pioglitazone treatment on histological grading of ankle lesions during adjuvant-induced arthritis. Animals were treated daily for 21 days with rosiglitazone (ROSI) 10 mg/kg (n = 8) or pioglitazone (PIO) 30 mg/kg (n = 8) by oral administration. Arthritic (adjuvant-induced arthritis (AIA)) (n = 7) and normal controls (n = 7) were given 0.5% carboxymethylcellulose alone. Cartilage degradation and bone erosion were graded as indicated in the Materials and methods section. Data are expressed as means ± SEM for five representative animals per group. *, P < 0.05 compared with normal controls; #, P < 0.05 compared with AIA controls (Mann–Whitney U test).
