Assessment of changes in H. pylori–induced gastric mucosal inflammation in the C57/BL6 mice model after treatment with CTB-UE. (A, B, C, D, E). Representative haematoxylin-eosin–stained stomach sections from the NC, MC, HD, MD, and LD groups (original magnification, × 200). (F). The histopathological changes in the gastric mucosa were determined for individual C57/BL6 mice in each group using ascoring scale. The bars indicate the mean±SD. Each group contained 8 samples (n = 8/group). *, P < 0.05 and **, P < 0.01 comparing 2 groups. NC: normal control group; MC: model control group; HD: high-dose group (200 μg); MD: middle-dose group (100 μg); LD: low-dose group (50 μg). Each group contains 8 animals.
