简介
Vitamin E (vit-E) is a lipophilic antioxidant, and its anti-inflammatory activity is still not full characterized. Thus, our goal was to investigate the anti-inflammatory effect of repeated vit-E treatment in the arthritis induced by the intraplantar injection of complete Freund’s adjuvant (CFA). We observed an increase in arthritis scores, interleukin-1β and H2O2 levels, neutrophil and macrophage infiltration, thermal hyperalgesia, mechanical allodynia, and loss of function induced by intraplantar CFA injection. These effects were unaltered after 1 day, partially reversed after 3 days, and inhibited after 9 days after vit-E treatment. Furthermore, the concentration of vit-E was reduced and that of tumor necrosis factor-alpha was increased in the CFA-injected paw. Both effects were reversed from 1 to 9 days after vit-E treatment. However, vit-E treatment did not alter CFA-induced edema at any time. Thus, vit-E treatment …
