Efficacy profiles for different concentrations of Lactobacillus acidophilus in experimental colitis

Figure 4 Effects of Lactobacillus acidophilus treatments on colitis-induced changes in intestinal histopathological features. A: Representative intestinal sections (HE, under light microscope, × 200) are shown. Panel 1: untreated model group, 2: negative-treatment (NS) model control group, 3-7: C4-C8 experimental treatment model groups respectively, 8: positive-treatment (prednisone acetate) model control group, and 9: normal control group; B: Average histopathological scores. ^aP < 0.05 vs untreated model control group; ^cP < 0.05 vs positive-treatment (prednisone acetate) model control group; ^eP < 0.05 vs normal control group.
