Effects of DSS and/or PBA supplementation on the DAI scores during 12 days of the experiment. Mean (A) weight loss score, (B) stool consistency score, (C) bleeding score, and (D) total DAI score (n=5 or 10 per group). The data are summarized as the means ± standard error. ^*P<0.05; ^**P<0.01 compared with the DSS control group, determined by one-way analysis of variance followed by Dunnet’s post hoc test. DSS, dextran sulfate sodium; PBA, sodium 4-phenylbutyrate; DAI, disease activity index.
