Macroscopical evaluation of protective effects of wheat peptides against gastric mucosal damage induced by ethanol. (a) Representative macroscopic photograph of the gastric mucosa in ethanol-induced gastric mucosal lesions in rats; (b) The gastric injury index of each group. Data are presented as mean ± SD (n = 10). Data are presented as mean ± SD (n = 10). ## p < 0.01 vs. normal control (NC) group, * p < 0.05 vs. ethanol model control (EC) group. A: NC, normal control; B: EC, ethanol control; C: omeprazole (OME), 20 mg/kgbw of omeprazole; D: low dose of wheat peptide (LWP), 0.1 g/kgbw of wheat peptide (WP); E: medium dose of wheat peptide (MWP), 0.2 g/kgbw of WP; F: high dose of wheat peptide (HWP), 0.4 g/kgbw of WP.
