Effects of Lycium barbarum polysaccharides (LBP) and capsaicin (CAP) on histological changes. (A) Representative distal colons stained by hematoxylin and eosin; (B) Histological scores. N: control group, U: ulcerative colitis induced group, L: LBP treated group, C: CAP treated group, M: mixed LBP and CAP treated group. Data are presented as mean ± SEM (n = 5). The arrow indicates erosion or ulceration of the epithelial layer. The * symbol indicates extent of inflammation. The dotted-line square indicates regeneration of the epithelial layer. ^## p < 0.01 compared to the N group. ^### p < 0.001 compared to the N group.
