Potential rat model of anxiety-like gastric hypersensitivity induced by sequential stress

Figure 9 Influence of the sequential stress on inflammatory response of gastric mucosa. A: On day 6 in early life only superficial sloughing of the mucosa was observed in the sequential-stress-treated group; B: Myeloperoxidase (MPO) activity assay at the same time demonstrated no statistical significance between two groups; C and D: after RS treatment, both histology and MPO activity test display no lesion or abnormality in the gastric mucosa of the two groups. MPO activity is represented as activity per unit of dry weight. Data were expressed as the mean ± SEM of the MPO activity (n = 8 in each group).
