(A, B) Images of the colons dissected from the control, DSS, and DSS+BYB3 groups. (C) The disease activity indices (DAIs) of the mouse colons were calculated based on body weight loss, stool consistency, and abnormal or gross blood-related characteristics. (D) Body weight changes were monitored and are depicted as a percentage of the initial body weight. The values represent the mean ± SEM from six mice. The results are representative of three separate experiments. Significant differences from the control group, *p < 0.05, **p < 0.01.
