L-arginine protects against ethylene glycol-induced gastric mucosal damage in rats: Immunohistochemical and electron microscopic study

Ethylene glycol is an alcohol widely used in industry as an antifreeze. It affects the normal gastric mucosal defense mechanisms, inducing surface ulcerations. L-arginine is a precursor of nitric oxide that exhibits multiple biological properties, among them is the acceleration of wound healing, especially in the stomach.
