Subject. The article presents clinical, biochemical, immunological and microbiological results of a complex of therapeutic measures of chronic gingivitis in patients with chronic gastroduodenitis. The aim of the study was to study the effectiveness of treatment of chronic gingivitis in patients with chronic gastroduodenitis with the use of the proposed method. Methodology. The subject of the study was 155 persons aged 19 to 25 years with diagnosed chronic gingivitis and chronic gastroduodenitis, which were divided by stratified randomization into three groups: 1 group (primary) - 52 patients; 2 group (positive control) - 52 patients; Group 3 (negative control) - 51 patients. All groups were comparable in age (F = 2,355, p = 0,092) and sex (χ2 = 2,133, p = 0,334). To study the state of free radical oxidation, the method of chemiluminescence (CL) of the oral liquid was applied on the device HL-003. The quantitative and qualitative content of oral microflora was determined using nutrient media: CHROMagar Orientation, CHROMagar Candida (France). The concentration in the oral fluid of the intercellular adhesion molecules sICAM-1 was carried out on the automatic enzyme immunoassay analyzer Lazurit and test systems manufactured by Vector-Best CJSC (Russia) and eBioscience (Austria). Results. The use of the complex proposed by us significantly improved the parameters of the clinical examination (dental indices). In addition, the state of free-radical oxidation has normalized: at previously increased values of the light-emission sum (S) and its maximum value (I max), during the time of the study, their decrease occurred, while the lowered values - the increase to the level of normal values. The level of microorganisms of the orange and red complex decreased to normal levels, and the level of sICAM-1 also significantly decreased. Conclusions. The scheme of treatment of chronic gingivitis with the use of NUTRIEL with laminaria and tooth elixir with chlorophyll in patients with chronic gastroduodenitis led to an increase in the duration of remission compared with the traditional treatment regimen.

Peroxidation Processes

Various pathologies, in particular hypertension, accompany violation of the processes of free radical oxidation. The state of the system lipid peroxidation – antioxidant protection can be assessed only by a complex of biochemical methods. The chemiluminescent method is used to obtain a faster result. The method has a number of advantages: measurement of chemiluminescence parameters is carried out in natural conditions and does not require sample preparation, is highly selective, it can be used to identify the presence of free radical pathology, analysis of the intensity of lipid peroxidation processes, the effectiveness of treatment with antioxidant medicament. The aim of the research was to study the lipid peroxidation under hypertension and stress by chemiluminescence. The experiment was conducted on male rats of the ISIAH line. The experiment consisted of 2 stages: stage of alarm and stage of chronic stress. We found that, depending on the type of stress, the state of the system lipid peroxidation-antioxidant protection differed. The role of stress in violation of the processes of lipoperoxidation in hypertension was established. The efficacy of the chemiluminescence method as an alternative to a complex of biochemical methods is shown. Express assessment of pro- and antioxidant status is possible for patients with hypertension.

Subject. Some features of the clinical picture, hygienic and microbiological state of the oral cavity, acidity and free-radical oxidation of the oral fluid in patients with recurrent aphthates on the background of acid-dependent diseases of the gastrointestinal tract are considered. The aim is to assess the relationship between clinical and laboratory parameters in patients with recurrent oral aphthae associated with acid-dependent diseases of the gastrointestinal tract. Methodology. A comprehensive clinical and laboratory examination of 58 young people with revealed recurrent aphthae of the oral cavity against the background of acid-dependent diseases of the gastrointestinal tract was carried out. The level of oral hygiene was assessed using the ONI-s index, the state of free-radical oxidation of the oral fluid - the "Chemilumimer-003" device, individual representatives of the normal flora were identified by inoculating the contents from the surface of aphthous elements on special differential diagnostic media of the HiCrome series. The acidity of the oral fluid was determined using a universal indicator litmus paper pH-1-14, short-term intragastric pHmetry was performed directly during fibrogastroduodenoscopy. Results. In 46.4 % of those examined, recurrent aphthae were found on the oral mucosa. In persons with chronic gastritis and duodenitis, the frequency of recurrences once a year was 37.9 %, 2-3 times a year ― 62.0, with the presence of chronic pancreatitis against the background of hyperacid gastric secretion ― 44.8 and 55.2, respectively. In patients with recurrent aphthae, a low level of oral hygiene, a violation of its microbiome, and a change in the acidity of the oral fluid were revealed. Conclusions. The presence of recurrent aphthae complicates individual oral hygiene, because accompanied by severe pain and paresthetic symptoms. This is manifested by an increase in the ONI-S index and a disturbance in the state of the normobiome in the form of an increase in the growth of resident microflora against the background of changes in the acidity of the oral fluid. Chemiluminescence indices correlate with the hygienic state of the oral cavity, qualitative changes in the normobiota and pH of the oral fluid in the studied clinical groups.

Objective: to study the main indicators of free radical oxidation and antioxidant protection in the erythrocytes of former athletes, depending on the period of termination of sports.Materials and methods: 24 former male athletes aged 19–29 years were examined, who were divided into 2 groups of 12 people each (1st group — former athletes who stopped training for up to 2 years; 2nd — over 2 years). The control group consisted of 15 practically healthy untrained student volunteers of the same age. In erythrocytes, spectrophotometrically (spectrophotometer Shimadzu 1240, Japan), the activity of antioxidant enzymes was determined: superoxide dismutase (SOD) (K.F. 1.15.1.1) — by inhibiting the reduction of nitro blue tetrazolium by superoxide anion radical at λ = 540 nm, after preliminary processing of erythrocytes by the method of Dubinina E.E. and others [8]; catalase (K.F. 1.11.1.6) — according to the rate of utilization of hydrogen peroxide at λ = 260 nm; glutathione peroxidase (HP) (KF 1.11.1.9) — by the change in the content of reduced glutathione in samples before and after incubation of the substrate with dithiobis-nitrobenzoic acid at λ = 412 nm; glutathione reductase (GR) (K.F. 1.6.4.2) — according to the catalytic NADPH ∙ H+-dependent transformation of the oxidized form of glutathione into the reduced form, the intensity of which was estimated by the rate of decrease in the extinction of samples at λ = 340 nm, at which the NADPH H+ solution has a maximum light absorption (Warburg test).Results: the direction of the shifts in the state of the oxidative balance was established depending on the period of detraining. A significantly lower value of the total antioxidant activity was revealed in the former athletes of the 1st group. This phenomenon is probably associated with a decrease in the efficiency of the enzymatic link of the antioxidant defense in the absence of regular physical exertion, and, as a consequence, an increased consumption of non-enzymatic antioxidants. It was found that the early post-sports period is characterized by significantly lower, in comparison with the control group, the values of the activity of the first-order enzymes (superoxide dismutase) against the background of the increased activity of the second-order enzymes (catalase).Conclusions: the obtained data can be recommended for monitoring the state of athletes who stopped playing sports and taken into account when prescribing rehabilitation measures for the corresponding contingent.

Radical Oxidation

In fact, Free radical oxidation is one of the required factors of homeostasis as far as the active forms of oxygen, which have unpaired electron, perform useful functions, they are necessary intermediaries of numerous processes of normal cells’ functioning such as biosynthesis of prostaglandins and leukotriene as well as other biologically active substances. Also, they take part in pathological processes such as: inflammation, fever and others. Free radical oxidation is the process of direct oxygen transferring to the substrate forming peroxide, ketones, aldehydes, etc. Some amino acids, proteins, water and carbohydrates prone to the processes of peroxidation, but crucial place is granted to lipids at the expanse of fatty acids which are included to their composition. The article highlights the information concerning the analysis of the state of antioxidant system of hens in the process of feeding them with subtoxic doses of fungicide of Derosal (BAYER, Germany) (0.1 LD50 for a fowl, 900 mg/kg of the body mass) which active ingredient is benzimidazole carbamate (carbendazim, BMC). It presents the changes of these indicators in the process of using pharmacological and natural antioxidants. The analysis has figured out that giving Derosal to the hens without corrections (II group) has been followed with the activation of the process of lipids’ peroxidation (POL) in the blood plasma, that is followed with the increase of concentration of primary and secondary lipoperoxidation products – diene conjugates (DC) and TBA-active products on the average up to 21.0–25.0 %, catalase activity – up to 38.5 % and decrease of superoxide dismutase activity (SOD) up to 21.8 % and АОА – up to 17.8 %, that shows the adverse effects of pesticides on the system of antioxidant protection of the organism. In the fowls’ groups III, IV and V the adding of antioxidant E-selenium, ascorbic acid and thermally untreated buckwheat seeds as the source of  quercetins and anthocyanins has led to the induction of antioxidant resources that is shown by the decrease in comparison with the control of content of diene conjugates, malonic dialdehyde and catalase (in average up to 13.6–33.6–18.0 % accordingly) and compensatory strengthening of superoxide dismutase activity and general activity of antioxidant (АОА) on the average up to 44.9–72.1–76.5 % and 15.3–13.4–21.7 % accordingly. In comparison with group II the activity of catalase has been lower as well as the activity of superoxide dismutase has been higher in all the groups almost in 1.5–2 times (Р ≤ 0.001).

Recently, interest in the problem of free radical oxidation in biological membranes, which is directly related to both the normal functioning of cells and the occurrence, course and outcome of many pathological conditions, has increased again in clinical medicine. The aim was to determine the role and impact of antioxidant defense in boys with hypoandrogenism. The study involved 75 adolescents with hypoandrogenism aged 13–18 years, who underwent a complex of clinical and laboratory examinations. All patients were conducted complex of anthropometric research and determination of the degree of delayed puberty, laboratory and instrumental examination. Free radical oxidation was determined by the levels of malondialdehyde, conjugated dienes, carbonated proteins, superoxide dismutase and catalase in the serum, and restored glutathione and glutathione peroxidase in whole blood. Based on their determination, the coefficient of oxidative stress was calculated. Statistical processing of results was performed using parametric and nonparametric methods. The study of indicators of the free radical oxidation process found that adolescents with hypoandrogenism have multidirectional changes in the oxidation of proteins and lipids, namely: the level of conjugated dienes increases, the concentration of malondialdehyde remains at the level of the control group, and the level of carbonated proteins tends to decrease. As for the activity of antioxidant protection enzymes, a significant decrease in the level of glutathione peroxidase was detected, while the level of superoxide dismutase and catalase remained at the level of normative indicators. Oxidative stress accompanies and is one of the pathogenetic links in the formation or maintenance of the state of hypoandrogenism in boys. This requires the use of antioxidants, the complex of which must be selected individually.

Introduction. Fluorine compounds in small doses, but with prolonged exposure, cause various disorders in organs at the cellular and molecular levels. Activation of free-radical processes plays an important role in the damaging eff ect of fl uorides. Th erefore, one of the most eff ective ways to limit fl uorine-induced damage is to directly aff ect free-radical processes using herbal preparations with antioxidant properties.The aim of the study is to study the eff ect of a dihydroquercetin-based drug on the activity of free radical processes in brain tissue under subchronic exposure to sodium fl uoride (NaF).Materials and methods. Th e work was performed on white male laboratory rats weighing 200-250 g. Th e rats were divided into 3 groups: 1 — control; 2 — rats with chronic exposure to sodium fl uoride (NaF) for 9 weeks; 3 — rats receiving a NAF solution with simultaneous administration of a complex drug based on dihydroquercetin at a dose of 3 mg/kg in 1% starch gel for 3, 6 and 9 weeks. The activity of free radical oxidation and antioxidant defense enzymes — superoxide dismutase (SOD) and catalase-was determined in the cerebral cortex. Th e level of expression of hypoxia-induced transcription factor HIF — 1A and inducible forms of proteins HSP72 and HSP32 were determined in the cytosolic fraction of brain tissue.Results. In the early stages of subchronic fl uoride exposure (1-3 weeks), the expression of protective proteins HIF-1α, HSP72, HSP32 and catalase was shown in the rat cortex, as a result of which the activity of free-radical processes was maintained at the control level. An increase in the timing of fl uoride intake to 9 weeks led to a decrease in antioxidant protection and signifi cant activation of free radical oxidation in brain tissue. Daily administration of a complex drug with dihydroquercetin for 3, 6 and 9 weeks to rats with subchronic fl uoride exposure led to a decrease in the severity of pro- and antioxidant balance disorders in the cerebral cortex. At the same time, the greatest protective eff ect of dihydroquercetin with fl uoride exposure was manifested by the 9th week of its administration.Conclusions. When subchronic intake of fl uorides in the body, the drug based on dihydroquercetin has a neuroprotective eff ect, which is manifested by an increase in the activity of antioxidant enzymes of fr ee radical oxidation and catalase and the resistance of the cortex to induced fr ee radical oxidation.
