Figure 1 Representative images of colons and colonic character assay. A: Representative images of colons; B: Colonic length; C: Colonic weight; D: Weight index of the colon. Data are mean ± SEM (n = 8). ^bP < 0.01, ^eP < 0.001, ^fP < 0.0001 vs normal group; ^aP < 0.05 vs TNBS group. TNBS: 2,4,6-trinitrobenzene sulfonic acid; APS: Astragalus polysaccharide; MES: Mesalazine.
