Representative immunofluorescence confocal images of occludin in colonic mucosa (a) and venules from different groups (b). The green zone represents the distribution of occludin and the blue zone nuclei. Bar = 25 μm. (c) Representative Western blot of occludin protein. (d) Quantitative analysis of occludin protein in colonic mucosa from different groups. Data were mean ± SEM (n = 5). *P < 0.05 versus Sham group; ^# P < 0.05 versus TNBS 15 d group.
