Effects of R1 on the activity of MPO and the levels of TNF-α and IL-6 in mice with DSS- or TNBS-induced colitis

Colon segments from mice (n = 6 per group) were excised and homogenized. The supernatants were assayed for the determination of the activity of MPO and the levels of TNF-α and IL-6 as described in Materials and Methods. Values are expressed as the mean ± S.D.
