MOD values of NF-κB p65 in the synovium (mean ± SD).

Group	NF-κB p65
Vehicle + control group	0.026 ± 0.006
Vehicle + MSU crystal	0.097 ± 0.022++
MSU + indomethacin (3 mg/kg)	0.047 ± 0.013∗∗
MSU + PRP15 (0.4 g/kg)	0.046 ± 0.003∗∗
MSU + PRP15 (0.8 g/kg)	0.038 ± 0.013∗∗
MSU + PRP15 (1.2 g/kg)	0.036 ± 0.016∗∗

For quantitation, 30 visual fields were analyzed from each group, five from each of the six sections from separate rats. From these, the MOD values were calculated. MOD: mean optical density. Data are means ± SD (n = 6). ⁺⁺ P < 0.01 versus vehicle-control group (control). ^∗∗ P < 0.01 versus vehicle with MSU crystal (model).
