Effect of a 5-day treatment with morusin (in mg/kg) on (A) interleukin 1β, (B) transforming growth factor β1, (C) superoxide dismutase and (D) catalase levels in TNBS-induced colitis, compared to the intact group, the untreated group (CTRL), and the group treated with sulfasalazine 50 mg/kg (SAS).

Values were obtained from Western blot analysis, quantified by densitometry, and normalized to the β-actin level, as described in Materials and methods. Representative blots are shown. The results are expressed as the mean, with error bars representing SEM. CTRL vs. intact group: ## p < 0.01; CTRL vs. treated groups: * p < 0.05, ** p < 0.01, *** p < 0.001.
