Abstract:
Background: The purpose of the present study was to study the potential anti-arthritic
and antioxidant effects of trehalose in an experimental model of complete Freund’s adjuvant
(CFA)-induced arthritis.
Methods: Arthritis was induced via subcutaneous injection of CFA (0.1) into the right footpad of
each rat. Trehalose (10 mg/kg per day) and indomethacin (5 mg/kg) as a reference drug were intraperitoneally
injected into CFA-induced arthritic rats from days 0 to 21. Changes in paw volume,
pain responses, arthritic score, and oxidative/antioxidative parameters were determined.
Results: Trehalose administration could significantly decrease arthritis scores (p <0.01) and paw
edema (p <0.001), and significantly increase the nociceptive threshold (p <0.05) in CFA-induced
arthritic rats. Trehalose also significantly reduced the pro-oxidant-antioxidant balance values when
compared to CFA treatment alone. In addition, no significant difference was found between the
trehalose group and indomethacin as a positive control group.
Conclusion: The current study suggests that trehalose has a protective effect against arthritis,
which may be mediated by antioxidative effects of this disaccharide.
