Probiotics increase T regulatory cells and reduce severity of experimental colitis in mice

Figure 2 Representative histological images and scores of mice. A: The normal group; B: The model group; C: The bifico group; D: The mesalazine group; E: Histological images and scores (hematoxylin and eosin, light microscope, × 100). Normal: In the normal group, the animals were administrated with physiological saline; Model: In the model group, the animals were challenged with 2,4,6-trinitrobenzene sulfonic acid (TNBS) without treatment; Bifico: In the Bifico group, the animals were challenged by TNBS and treated with Bifico at 345 mg/kg; Mesalazine: In the Mesalazine group, the animals were challenged by TNBS and treated with 300 mg/kg mesalazine. Data are means ± SE (n = 10). ^bP < 0.01 vs the normal group; ^dP < 0.01 vs the model group.
