Analysis of the results of the questionnaire of orthodontists and children dentists of poltava-city on the optimization of orthodontic aids for children.

Objective: Introduction: In the course of the study, we identified high prevalence rates of orthodontic pathology and identified organizational aspects regarding the provision of orthodontic care for children, and identified the need for their optimization. The aim: The purpose of the study was to analyze the results of the questionnaire of orthodontists and children's dentists, who provide dental care to the children of the Poltava region, about the importance of optimization of orthodontic care for children and improving the knowledge of doctors about the risk factors for the onset of orthodontic pathology.

Patients And Methods: Materials and methods: Methods: Sociological (questionnaire), medical-statistical, bibliosemantic.

[IMPACT OF EMOTIONAL STRESS ON THE IMMUNE SYSTEM INDICES AMONG RESIDENTS OF RADIATION CONTAMINATED AREAS.].

The aim of this research is to study special characteristics of immune system functioning among residents of the areas contaminated with radionuclides, under conditions of additional emotional load. We examined 350 people, including a group of radiation free areas residents (control group, 150 people) and a group of residents living in the areas of enhanced radiation monitoring (IV radiation zone, the density of soil contamination with isotopes (137)Cs 1-5 Ki/km(2), 200 people). All examined are the students of Cherkassy State University, aged 18-24 years, at the time of research didn't have any acute diseases.

[Synthesis of 3-hydroxybutyrate-CO-4-hydroxybutyrate copolymers by hydrogen-oxidizing bacteria].

Synthesis of 3- and 4-hydroxybutyrate copolymer (3HB-CO-4HB), the most promising member of the biodegradable polyhydroxyalcanoate (PHA) family, has been studied. Cultivation conditions of naturally occurring strains of hydrogen-oxidizing bacteria Ralstonia eutropha B5786 and Cupriavidus eutrophus B10646 have been optimized to ensure efficient synthesis of the 3HB-CO-4HB copolymer. A set of highly pure samples of the 3HB-CO-4HB copolymer with 4HB content varying from 8.

[Normobaric hypoxia effects on some parameters of cellular immunity of persons with different blood groups].

We investigated influence of the normobaric hypoxia on separate parameters of cellular immunity of persons with different groups of blood (system ABO). It was established presence of varied direction of immunity changes, which expressiveness depend on the certain antigens (system ABO) The most sensible to hypoxia immunostimulation was immune system of persons with II group of blood, the lowest- with the IV group.

[Modification of T-cell activation marker expression by peripheral blood lymphocytes of persons living in radiation polluted territories].

Investigation to effect of low radiation doses in the T-cells activation surface markers expression of resident in 4 radiation zone around Chernobyl. Was observed the increase cells level, which CD4+CD25+ and CD4+HLA-DR(+)-cells markers expression. Were revealed the increase of the apoptosis related CD4+CD+ cells level in peripheral blood.

[The effect of normobaric hypoxia on the indices of the cardiorespiratory and immune systems in the inhabitants of radiation-contaminated regions].

The results of normobaric hypoxia therapy in patients from ecological clean regions of Ukraine and patients from ionizing radiation pollution regions are analyzed. The positive effect is obtained in both groups. It is shown that intermittent normobaric hypoxia normalize the state of the blood circulation, respiration, hemopoiesis and immunological reactivity.

[The free-radical involvement of the salivary gland in stress].

It has been demonstrated in rat experiments that acute emotional painful stress enhanced free-radical lipid oxidation in salivary gland tissues and reduced the activities of antioxidant enzymes in it. Similar processes take place in the blood. Antiaggregation activity increases in the tissues of salivary gland, this being an essential adaptation factor in stress, preventing microcirculatory disorders in the tissues.

[Human physiological blood protection systems in the late periods after ionizing radiation exposure related to the accident at the Chernobyl Atomic Electric Power Station].

During a 5-year follow-up of rescue party members exposed to radioactive effects of the Chernobyl accident no material changes were observed versus healthy donors in the content of calcium, cholesterol, atherogenic lipoproteins, dienic conjugates, insulin, thyroxin, triiodothyronine, thyroglobulin, IgA, IgG and fibrinogen. Inhibition of peroxidation and emergence of hypocoagulation are attributed to a reduced respiratory splash of the neutrophils. Concentrations of hydrocortisone, testosterone, IgM rose, while the activity of some antioxidant enzymes remained stable.
