ABSTRACT
The results of morphological research of stomach's mucouse membrane in children with functional dyspepsia are presented in the article. Microscopic changes were found in all examined children regardless of endoscopic state of the gastric and duodenum mucosa. Microscopic picture of the epithelium damage and regeneration was revealed; in more complicated cases, under the decline of regeneration potential features of interstitial inflammation appear. Actuality of morphological research in differential diagnostic of functional dyspepsia and chronic gastritis in children has been shown.

The article presents the current views and controversial issues problems comorbidity upper gastrointestinal tract in children and adolescents (gastroesophageal reflux disease and gastroduodenal diseases). Analyzed their own long-term observations, depending on the type of disease, severity of motor disorders, endoscopic and morphological picture, infection Helicobacter pylori. The possible options for the formation of gastroesophageal reflux disease in children and adolescents with gastroduodenal diseases.

Morphofunctional characteristics of industrial microorganisms belonging to different genera, species, and strains were investigated after 15 to 20 years of storage in liquid nitrogen. The taxonomic position of microorganisms, the cell physiological state prior to storage, and the cryoconservation regime were found to affect microbial cryoresistance. Protective media, density of cell suspensions, freezing rate, and heating temperature are the parameters important for development of efficient technologies for cryoconservation of industrial microorganisms at -196 degrees C.

Phagocytic activity of peritoneal macrophages in cases of separate and combined injections of killed bacterial vaccines and prospidin has been studied in the work. As a result of researches conducted, it has been found out that the injection of vaccines together with prospidin makes it possible to reduce an inhibiting effect of prospidin on phagocytic activity of monocyte-macrophagal cells; first of all it concerns their digestive activity. Thus, the immunodepressing effect of antiblastome drugs may be reduced with the help of injection of killed bacterial vaccines which stimulate nonspecific factors of organism protection, including antineoplastic ones.

The possibility of monooxygenase enzymes biomimetic construction models with the use of polynuclear manganese complexes was shown. It was demonstration that benzene is oxidized by polynuclear manganese complex [Mn12O12(CH3CO2)16(H2O)4] in acetonitrile solution at room temperature and atmospheric pressure yielding phenol with the selectivity more than 80%. It was determined that the addition of air oxygen as the reoxidizer to the reaction mixture didn't transfer the reaction into the catalytic mode.
