Fig. 3.

Effects of cyclic nigerosylnigerose (CNN) on the histology and the number of goblet cells in the colonic tissue of mice with DSS-induced colitis. (A) Representative images of H&E-stained colonic tissues. (B) Histological score. (C) Representative images of colonic tissues stained with Alcian Blue (AB). (D) Number of AB-positive cells. AB-positive cells are indicated by arrows. Con: control group; DSS: DSS group; CNN-DSS: CNN-DSS group. Data are expressed as the mean ± SEM. Each section is shown at 200× magnification. The black scale bar indicates 100 μm for all panels. Values without a common letter are statistically significantly different (p<0.05).
