Fig 8. Effects of V. pubescens on the histology of the stomach wall in ethanol-induced gastric mucosal damage in rats.

(G1) (Normal control group); (G2) (Ulcer control group); (G3) (Omeprazole); (G4) (62.5 mg/kg), (G5) (125 mg/kg), (G6) (250 mg/kg) and (G7) (500 mg/kg) of V. pubescens extract. There were 6 rats in each group of experiment. The rats in the experimental groups (groups 4–7) exhibited markedly better protection of the gastric mucosa, as shown by the reduced ulcer area (white arrow), submucosal edema and leucocyte infiltration (blue arrow) of the submucosal layer (H&E staining magnification 10×).
