Oral COS administration ameliorated intestinal mucosal damage and reduced the inflammatory response in DSS-induced colitis mice. (A) Images of H&E-stained colon and ileum sections from DSS-treated mice with or without COS administration. The scale bar is 200 μm or 100 μm, as indicated in the respective images. Pathological scores of these tissues were calculated. (B) The levels of IL-6, IL-1β and TNF-α in serum were detected by ELISA. (C) The level of MUC2 in colonic tissue was detected by ELISA. *, p < 0.05, **, p < 0.01, n = 6.
