Активність синтази оксиду азоту та вміст пероксинітриту у клітинах слизової оболонки шлунка щурів за умов експериментальної стресової виразки
Nitric oxide synthase activity and peroxynitrite content in cells of rat’s mucous coat of stomach under experimental stress-induced ulcer

Summary/Abstract: Nitric oxide synthase activity in gastric mucosal cells as well as peroxynitrite generation in experimental stress-induced gastric ulcer formation in rats were studied. There was made the conclusion that nitric oxide synthase activity is growing during the stress. It causes increasing of peroxynitrite’ production and ulcer formation. It was established that destructive gastric mucosal damages depend on stress’ duration. It was determined that nitric oxide is involved in complex pathogenetic mechanisms of ulceration.
