Abstract:
AIM: To explore the effects of sodium ferulate (SF) on function of macrophages in colonic tissue of the colitis rats in vivo. METHODS: The immunological colitis model of rats was produced. SF was used intracolonically for 21 days. The contents of malondialdehyde (MDA), nitric oxide (NO), prostaglandin E_2 (PGE_2) and the activity of superoxide dismutase (SOD), interleukin-1 (IL-1), TNF-?, myelopexoxidase (MPO), and the expression level of NF-?B p65 in colonic tissue of the rats were detected. RESULTS: SF (200,400,800 mg/kg) decreased the elevated contents of MDA, NO, PGE_2, the activity of IL-1, TNF-?, MPO, and the expression level of NF-?B p65, while increased the reduced activity of SOD in colonic tissue of the colitis rats in a dose-depended manner. CONCLUSION: SF restrained the activity of activated colonic macrophages and relieved the colonic inflammation reaction in vivo in colitis rats, which may be related to the suppression of NF-?B activation.
