[Functional state of the hematosalivary barrier in children with gastroduodenal diseases].

The hematosalivary barrier state was studied using the values of peroxidation of lipids and nitric oxide, antioxidant defense and macroelements in children with chronic gastroduodenitis and functional dyspepsia. The disturbances of the barrier functioning were shown to be important in the mechanisms of stomach and duodenum lesions. Taking into account significant changes in the metabolic profile of the sputum, which are different for different inflammatory and functional diseases of the gastroduodenal zone, we have suggested using its parameters for noninvasive screening diagnostics of this pathology.
