^a Score and microscopic score data are expressed as median (range) and were statically evaluated by non-parametric Kruskal-Wallis test; ^b Extension of lesion and colonic weight data are expressed as mean ± SEM values and differences were assessed using ANOVA was followed by post hoc test of Dunnet; Adherence was expressed in percentage and was analyzed with the χ² test. *P < 0.05, P < 0.01 and P < 0.001 versus TNBS control group.
