Abstract

The aqueous extract of Schisandra chinensis, Evodia rutaecarpa and meal (SEM-Ex) has been traditionally used in the Oriental countries as an astringent. However, little is known about the effects of aqueous extract of SEM-Ex on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SEM-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SEM-Ex was orally administered from day 2 of DSS treatment in the different dose (10-50 mg/kg body weight). SEM-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. Moreover, SEM-Ex suppressed significantly not only the serum haptoglobin levels and the activities of myeloperoxidase (MPO), but also the colon tissue expression levels of monocyte chemoattractant protein-1 (MCP-1) in DSS-induced mice. In contrast, SEM-Ex increased significantly the colon tissue expression levels of granular colony stimulating factor (G-CSF) well known as anti-inflammatory cytokine. These results suggest that SEM-Ex administration could reduce significantly the clinical signs and regulate of chemokine and anti-inflammatory cytokine in DSS-induced model mice. Therefore, these properties may contribute to the strong anti-ulcerative colitis (UC) response effect of SEM-Ex.
