title: [Parameters of reactive oxygen species and nitric oxide metabolism in people with high arterial blood pressure].
abstract: An exchange of active forms of oxygen and nitric oxide in normal conditions and under the development of oxidative stress in humans with high of arterial blood pressure was studied. The activity of NO-synthase was estimated in the human thrombocytes. The nitric oxide formations were determined by the quantity level of its final metabolites--nitrites and nitrates. The peroxynitrite formations were determined by the quantity level of 3-nitrotyrosine. An analysis of the investigation results has shown the increase of processes of oxidative stress, violation of nitric oxide formation in humans with high arterial blood pressure. Application of ascorbic acid allows to reduce the level of free radicals and to increase the formation of nitric oxide, but does not result in statistically reliable changes of the parameters describing formation of peroxynitrite and products of peroxide oxidation of lipids in humans with high arterial blood pressure. Application of ascorbic acid does not result in changes of researched parameters in the control group.
