Hydrogen-rich water protects against inflammatory bowel disease in mice by inhibiting endoplasmic reticulum stress and promoting heme oxygenase-1 expression

Figure 2 Hydrogen-rich water alleviates the changes in colon length, thickness and macroscopic score in dextran sulfate sodium-induced inflammatory bowel disease. Mice were sacrificed, and the colons were rapidly removed and processed for analysis on the 7^th d after inflammatory bowel disease (IBD) modeling. A: The representative pictures of the colons in each group; B-D: The macroscopic score, length, and the thickness of the colons from each group. n = 6, mean ± SEM, ^aP < 0.05 vs control group; ^bP < 0.05 vs dextran sulfate sodium (DSS) group. HRW: Hydrogen-rich water.
