Stress induced gastric mucosal inflammation in mice. The mice were placed under immobilization stress for 2 h per day for 2 weeks. Stomach tissues were extracted from the stressed and control mice and were analyzed via H&E staining. The values for the stressed mice are presented in comparison with those of the control mice and are expressed as mean±SD (n=15). Dot-plot and median were used to test the differences between the stress and control groups. (A) Accumulation of neutrophils (as shown in asterisks) and lymphocytes (as shown in arrows) in stomach tissues following 2 weeks of restraint stress (200× magnification, bar=50 µm). (B) Histopathological score of control and stressed mice.
