Results: Small round or linear haemorrhagic erosions were induced in the oxyntic glandular area after rats exposed to WRS. Meanwhile, GMBF decreased and NO contents in plasma and gastric mucosa increased significangly compared with those without WRS. L-NAME not only further decreased GMBF and inhibited the increases of NO contents but also aggravated the extent of gastric mucosal lesions. In contrast, L-Arg increased both GMBF and NO contents resulting in the lessening of mucosal injuries. All these changes were significant compared with control group.
