Diphenyl diselenide attenuates oxidative stress and inflammatory parameters in ulcerative colitis: A comparison with ebselen.

Objetive: The aim of this study was to evaluate the effects of diphenyl diselenide (PhSe)2 and ebselen (EB) in ulcerative colitis (UC) induced by dextran sulfate sodium (DSS) in rats.

Methods: The effects of (PhSe)2 and EB in rats submitted to DSS-induced colitis were determined by measurement of oxidative stress parameters, inflammatory response and bowel histopathological alterations.

Results: Animals developed moderate to severe neutrophil infiltration in histopathology assay in DSS rats and (PhSe)2 improved this response.
