PHI treatment improved the intestinal mucosa barrier of colitis colon tissues. (A) Protein levels of ZO-1, E-cadherin, and occludin in colons were detected by Western blotting. (B,C) Immunohistochemical staining of ZO-1 and occludin (scale bar = 100 μm). (D) Apoptosis of colon tissues were subjected to TUNEL staining (scale bar = 100 μm). (E) Goblet cells were detected by AB-PAS staining (scale bar = 100 μm). # P < 0.05, ## P < 0.01, and ### P < 0.001 vs. control group. * P < 0.05, ** P < 0.01, and *** P < 0.001 vs. DSS group. (n = 3–6 mice per group).
