The present study was intended to elucidate the effect of rutin, a flavonoid, on arthritis in complete Freund's adjuvant-induced arthritic rats. The present study showed that more pronounced effect has been observed in the case of 15 mg/kg dose of rutin, with significant reduction in paw diameter together with positive modulation of hematological parameters as compared to 2 other tested doses. A significant upsurge in the level of superoxide dismutase, glutathione peroxidase and glutathione were observed together with decrease in the level of malondialdehyde after treatment with rutin in a dose-dependent manner. Furthermore, the effect of rutin on the tumor necrosis factor-α and interleukin-1β in arthritic rats showed does-dependent lowering of these cytokines with maximum benefit at 15 mg/kg dose and the level of both NF-κB p65 and NF-κBp65 (Ser536) has been significantly reduced in the presence of rutin. Histopathological examination showed that the inflammatorycells infiltration, synovial hyperplasia, pannus formation and cartilage and bone erosion had considerably improved on administration of rutin. In conclusion, our paper strongly demonstrated the protective effect of rutin against the rheumatoid arthritis involved via suppression of NF-κB p65 protein expression.
