DSS or TNBS affects body weight (A), colon length (B), macroscopic score (C) and intestinal myeloperoxidase activity (D) in C3H/HeN and C3H/HeJ mice. A histopathological exam was performed by hematoxylin-eosin staining (E). The mice treated with DSS or TNBS were sacrificed on the 7th and 3rd day, respectively: the white bar, normal group; and black bar, DSS or TNBS-treated group. The values of enzyme activities indicate the mean ± S.D. (n = 7). * Significantly different compared with normal group (p < 0.05).
