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

Figure 4 Hydrogen-rich water decreases the oxidative stress in dextran sulfate sodium-induced inflammatory bowel disease. On the 7^th d after inflammatory bowel disease (IBD) modeling, the colon tissues were harvested to evaluate the oxidative stress. The levels of MDA, MPO, SOD and GSH in the colon tissues were measured. n = 6, mean ± SEM, ^aP < 0.05 vs control group; ^bP < 0.05 vs dextran sulfate sodium (DSS) group. HRW: Hydrogen-rich water; MDA: Malonaldehyde; SOD: Superoxide dismutase; GSH: Glutathione.
