Effects of wheat peptides in improving gastric mucosal blood flow (GMBF) and relevant protection factors in rats with ethanol-induced gastric lesions. (a) The changes of GMBF measured by the laser doppler flowmeter instrument; (b) Plasma levels of endothelin (ET)-1; (c) Plasma levels of nitric oxide (NO); (d) Gastric prostaglandin E2 (PGE2). Data are presented as mean ± SD (n = 10). ## p < 0.01 vs. NC group, # p < 0.05 vs. NC group, ** p < 0.01 vs. EC group, * p < 0.05 vs. EC group. NC, normal control; EC, ethanol control; OME, 20 mg/kgbw of omeprazole; LWP, 0.1 g/kgbw of WP; MWP, 0.2 g/kgbw of WP; HWP, 0.4 g/kgbw of WP.
