Figure 1. Changes in DAI score and colon weight per length.

Figure 1

(A) DAI was calculated by the sum of three clinical scores (stool consistency, rectal bleeding, and weight loss) during the DSS treatment period. Significant differences comparing scores to values on day 0 (before DSS treatment) were determined by Dunnett’s multiple comparison test (**P<0.01, ***P<0.001). (B) Colon weight per length with or without DSS treatment. Two-way ANOVA P values for the colon weight per length (diet and treatment) were 0.0047 for diet, <0.0001 for treatment, and 0.0053 for the interaction between diet and treatment. No significant difference was observed for strain. Significant differences between the untreated group and the 2% DSS-treated group were determined by an unpaired two-tailed Student’s t-test (**P<0.01, ***P<0.001). Values are expressed as means ± SEM (n = 5–7).
