Unconjugated bilirubin alleviates experimental ulcerative colitis by regulating intestinal barrier function and immune inflammation

Figure 3 UCB ameliorated colon tissue injury in DSS induced colitis mice. A: Light microscopic assessment of hematoxylin and eosin stained sections; B: Histological scores (images acquired at 10 × using Olympus BX60; scale bar =100 μM; images acquired at 20 × using Olympus BX60, scale bar = 50 μM, n = 3); C: MPO activity of colon tissues (n = 5). Data are expressed as means ± SEM. ^cP < 0.001 vs control group, and ^fP < 0.001 vs DSS. UCB: Unconjugated bilirubin; DSS: Dextran sodium sulfate; MPO: Myeloperoxidase; SEM: Standard error of the mean.
