Abstract
Objective: To research curcumin on rheumatoid arthritis (RA) symptoms. Materials and Methods: Dividing Sixty SD male rats among six groups: normal control group, model group, dexamethasone (DXM) group and curcumin low, medium and high dosage groups (25, 50, 100 mg/kg body
weight) every days. We adopted the CIA (collagen induced arthritis) rat model. All rats were subjected to 28 days of intragastric administration wherein we observed the rats’ state, weight, degree of paw swelling, arthritis index and pathological changes of ankle joints. Their serologic
contents of IL-1β, IL-6 and TNF-α were examined by Elisa method and IKK-α, IKK-β and NF-κB in joint synovial tissues were tested via IHC assay. Results: Curcumin inhibited paw swelling within the CIA rat model, decreasing
the serologic content of IL-1β, IL-6 and TNF-α. It also decreased the protein expressions of IKK-α, IKK-β and and NF-κB in synovial tissues. Its effects were dose-dependent and weaker than those of DXM. Conclusion: Curcumin
is effective against RA by means of transcribing the IKK-α/-β/NF-κB pathway
