RvE1 reduces leukocyte infiltration and proinflammatory mediators in colitis. (A) Myeloperoxidase activity of colons of mice treated with TNBS alone or RvE1. *, P < 0.0001 vs. mice treated with TNBS alone. (B) Anti-TNBS IgG level in serum on day 4 from mice treated with TNBS alone or RvE1 as noted. *, P < 0.01. (C) Quantitative real-time PCR analysis of mRNA expression of inflammatory mediators in colons obtained on day 4 from control mice (white column), mice treated with TNBS alone (black column), or mice receiving TNBS plus RvE1 (gray column). *, P < 0.01.
