MPO and colitis: In all animals treated with infliximab, weverified a significant reduction in the tissue levels of MPO, regardless of theconcentration used, when compared to those submitted to intervention with saline.Differently from what has been shown by other authors who evaluated the efficacy ofinfliximab in experimental models of TNBS-induced colitis, in this study weidentified greater reduction of MPO levels in infliximab-treated animals especiallywhen higher concentrations were used (10 mg/kg/weeks).
