Figure Lengend Snippet: Stress decreased the gastric expressions of antioxidants in mice. The mRNA and protein expression levels of antioxidant enzymes in the stomach tissue of control mice and stressed mice were analyzed by quantitative RT-PCR and Western blot, respectively ( A – E ). The values for the stress mice are presented in comparison with those for the control mice and are expressed as mean±SD ( n =15). Student’s t -test was performed to test the differences between the stress and control groups.
