The chronical gastritis Helicobacter pylori correlated: immunohistochemical behaviour of nitric oxide synthase isoforms in rat's stomach

Abstract

Recent non extensive studies indicate that Nitric Oxide (NO), a novel intercellular messenger, may play a role in pathogenesis of gastric lesions by Helicobacter pylori (Hp). Aim of this study is to evaluate the immunohistochemical distribution and modification of NO synthases (cNOS - iNOS) in experimentally induced gastritis by Hp in rats.
