The aim of the study was to investigate the content of spontaneous protein oxidative modification (POM) in the blood serum and pulmonary tissue of rats after local gamma irradiation of the projection area of the heart and lungs. The content of products of spontaneous POM (aliphatic neutral and basic aldehyde- and ketone-dinitrophenylhydrazones) in the blood serum and pulmonary tissue of 57 rats was studied. The animals were divided into 5 groups: “control group”, where there was gamma irradiation of the heart and lungs area, the collection of samples was done at the next day; “treatment group”, where a single session of low-intensity broadband red light was performed after local exposure to gamma radiation (the collection of samples was done at the next day); “chronic control group”, where there was an exposure to local gamma irradiation of the heart and lungs area, the collection of samples was done at the fourth day; “chronic treatment group” was daily exposed to low-intensity red light for 4 days after local exposure to gamma radiation, the collection of samples was done at the fourth day; “normal level group” was not exposed to either gamma radiation or broadband red light. In the pulmonary tissue and blood serum of control animals, a gradual increase in the content of spontaneous POM products was observed. The most significant difference from the normal level the “chronic control group” had. At the same time, the normalization of the content of POM products under the influence of low-intensity broadband red light in the tissues of the experimental groups was revealed. In the course of the experimental study, the normalization of processes of free radical oxidation of proteins in the lung tissue and in the serum of rats after gamma irradiation and the exposure of the projection region of the heart and lungs to low-intensity broadband red light was shown. Thus, low-intensity red light can be considered as a possible radioprotector.

Introduction. The inflammatory-dystrophic process in periodontium is accompanied by its hypoxia, which causes the activation of free radical oxidation processes. Tissue destruction in periodontal diseases is considered to be the result of an altered inflammatory/immune response to microbial plaque and involves massive release of neutrophils, reactive oxygen species and enzymes. The aim of the study – to establish the protein oxidative modification in blood and periodontium in case of periodontitis combined with hyper- and hypothyroidism in rats. Research Methods. Experimental studies were carry out on 48 mature male, nonliner, white rats, which were divided into the following groups: І – control animals; ІІ – animals with periodontitis; ІІІ – animals with periodontitis combined with hyperthyroidism; IV – animals with periodontitis combined with hypothyroidism. Protein oxidative modification (POM) was determined in blood serum and periodontium homogenate by the method of I.F. Meschyshyn. Results and Discussion. The results of our studies showed that the intensity of the processes of protein oxidative modification was significantly increased in animals of all experimental groups vs control group. The content of aldehyde- and ketone derivatives of the alkali nature changed more pronounced than the content of aldehyde and ketone derivatives of neutral nature. Conclusions. Thus, the experimental periodontitis is accompanied by a marked increase in the intensity of the protein oxidative modifications both in the homogenate of periodontal tissues and in the blood serum. Imbalance of thyroid hormones increases oxidative stress in experimental periodontitis, especially pronounced in hyperthyroidism.

Aim. To study the influence of substrate for nitrogen oxide (II) synthesis - L-arginine - and non-selective NO-synthase inhibitor - N-nitro-L-arginine-methyl ester - on protein oxidative modification in combination with rats’ thymocytes cathepsin H activity estimation in vitro. Methods. The study was performed on male Wistar rats with body weight of 280-320 g. Freshly-separated thymocytes were incubated in vitro in the full nutrient medium containing 5 мМ of N-nitro-L-arginine-methyl ester (n=8) or 5 мМ of L-arginine for 24 hours at the temperature of 37 °C (n=8). Control group consisted of thymocytes incubated in the same conditions in the full nutrient medium (n=8) for 24 hours. Nitric oxide metabolites levels were measured by spectrophotometry in the visible spectrum using the reaction with Griess reagent. Cathepsin H activity was estimated by BarrettKirschke spectrofluorimetry. Protein oxidative modification was measured by R.L. Levine method in E.E. Dubinina modification followed by carbonyl derivatives absorption spectrum quantitative analysis. Results. In nitrogen oxide (II) synthesis deficiency model, protein oxidative modification degree increased, mainly due to basic and neutral aldehyde- and ketone-dinitrophenylhydrazones level increase. Those changes were accompanied by increased activity of cathepsin H. In nitrogen oxide (II) synthesis stimulation model, level of oxidative-modified proteins decreased, mainly due to lower levels of neutral amino acid derivatives, cathepsin H activity didn’t change. Conclusion. In vitro nonselective inhibitor of inducible NO-synthase - N-nitro-L-arginine-methyl ester - stimulates protein oxidative modification and increases activity of cathepsin Н; substrate of NO synthesis - L-arginine - showes antioxidant effect.

Background: Zingerone is one of the active components of ginger that possesses multiple biological activities and anti-inflammatory properties against either radiation effect or cisplatin toxicity. Purpose: to examine the protective effect of zingerone against gamma radiation (IR) or cisplatin-induced immunotoxicity. Material and Methods: 48 rats were divided into six groups as follows: (group-1); normal control group received distilled water; (group-2); rats received Zingerone orally at a dose of 25 mg/kg b.wt. Once / day for 14 consecutive days (Zing.). (group-3); Rats were given a single injection of Cisplatin at a dose of 7.5 mg/kg b.wt. intraperitoneally (Cispl.). (group-4); Rats exposed to a single dose of 6 Gy whole-body gamma irradiation using 137Cesium source in a Gamma cell 40 (Rad.). (group-5); rats received same dose of Zingerone then they were exposed to gamma radiation as in group 4 (Zing+Rad.). (group-6); rats received Zingerone followed by single injection of Cisplatin at the dose of 7.5 mg/kg b.wt. Intraperitoneally (Zing+Cisp.). Results: Exhibited a significant increase in expression of NF-κB, IL-10, caspase-3, and gene expression of TNF-α as well as oxidative stress biomarkers (MDA and NO) levels accompanied with a reduced level of SOD in either whole body-irradiated or cisplatin-received group. Conversely, pro-inflammatory cytokines levels were significantly decreased with an improvement of oxidative stress in groups that received zingerone. Conclusion: It could be concluded that zingerone exerts its antioxidative activity and immunomodulatory effects through inhibition of pro-inflammatory mediators induced by whole body-gamma irradiation or cisplatin administration at two time interval early and late stage of radiation exposure (after 2 h and one week).Therefore, further studies are required to elucidate the molecular signaling pathway concerning zingerone.

The aim of this study was focused on investigating the possible protective effect of erdosteine against gamma radiation-induced renal lesions in male albino rats. Twenty-eight albino rats were divided into four equal groups as follows: control group, irradiated group (animals subjected to whole-body gamma irradiation at a dose of 5 Gy), treated group (each rat received 100 mg/kg body weight once daily, orally by gastric tube, erdosteine for 1 week), and treated irradiated group (each rat received 100 mg/kg body weight once daily, orally by gastric tube, erdosteine for 1 week, then exposed to whole-body gamma irradiation at a dose of 5 Gy). The results revealed that the administration of erdosteine to rats before irradiation significantly ameliorated the changes occurred in kidney function (creatinine and urea) compared with irradiated group. Also the changes in serum tumor necrosis factor α, interleukin 1β, and interleukin 6 activities were markedly improved compared with the corresponding values of irradiated group. Kidney catalase and glutathione peroxidase (GPx) activities and reduced glutathione concentration showed approximately normal level when compared with the irradiated group. The histopathological results showed distinctive pattern of renal lesions in irradiated group, while in treated irradiated group the renal tissues showed relatively well-preserved architecture. Erdosteine acts in the kidney as a potent scavenger of free radicals to prevent or ameliorate the toxic effects of gamma irradiation as shown in the biochemical and histopathological changes and might provide substantial protection against radiation-induced inflammatory damage.

The effect of low-intensity laser radiation on the biochemical, immune and clinicalstatus of hypotrophic calves was studied. The studies were carried out in 2 groups(test and control ones) of 12 animals with symmetric moderate hypotrophy. Thecalves in the test group underwent low-intensity laser irradiation of blood withinthe red spectral range (wave length of 630 nm). The animals of the control group(intact) were not treated. Clinical observations of the calves were carried out during2 months, taking into account the incidence, duration and severity of the course ofthe disease, as well as the calves’ weight gain. Blood sampling for biochemical andimmunological studies was performed on the 1st and the 21st days of the calves’life. On the first day the biochemical status and natural resistance in the animals ofthe both groups did not differ. On the 21st day, the calves of the test group hadhigher levels of glucose, pyruvic acid, vitamin E, Blood Serum ComplementActivity (SCA), Blood Serum Lysozyme Activity (SLA), Leucocyte PhagocyticActivity (LPA), Phagocytic Number (PN), Phagocytic Intensivity (PI), and lowerlevels of lactic acid, middle molecules and ectoglobular hemoglobin in comparisonwith the control group. The treatment of the animals with low-intensity laserradiation positively affected their clinical state and productivity. The calves in thetest group had mild forms of gastrointestinal diseases with a shorter courseduration, and the increase in body weight was significantly higher compared withthe control group. The positive effects of low-intensity laser radiation onbiochemical status, natural resistance and clinical condition of hypotrophic calveswere established, which allows us to recommend it for their rehabilitation.

Objective: In this article aims to investigate the radio-protective effect of hesperidin on the liver of Sprague Dawely rats.Material and Methods: 40 male Sprague Dawely rats were selected randomly and divided into 8 groups. Group 1 did not receive radiation and hesperidin (sham control). Group 2 received only 100 mg/kg body weight (b.w) of hesperidin for 7 consecutive days (HES group); group 3 exposed to dose of 2Gy whole-body gamma radiation (2Gy group), and group 4 and 5 received 50 and 100 mg/kg b.w of HES for 7 consecutive days before 2 Gy gamma radiation, respectively.Group 6 exposed to dose of 8Gy gamma radiation (8Gy group); group 7 and 8 received 50 and 100 mg/kg b.w of HES for 7 days before 8Gy gamma irradiation, respectively. Histopathological evaluation was perfomred 24 hours after radiation.Results: Administration of hesperidin (50 mg/kg b.w, 7 days) before 2Gy of gamma irradiation led to remove inflammatory mononuclear cells in the portal space, but there was still dilation of central veins while hesperidin at a dose of 100 mg/kg before 2Gy gamma radiation was observed with normal liver structure. Microscopic findings in the groups receiving two doses of hesperidin (50 and 100 mg/kg b.w, orally, 7 days), before 8Gy of gamma radiation, were similar in a way that extreme dilation of central veins to be seen, however, there was no capillarization.Conclusion: HES can be offered as a suitable radio-protector in radiotherapy patients and radiation workers.

Aim. To investigate in vitro effects of 5 mM L-Nω-nitroarginine methyl ester and 0.1 mM sodium nitroprusside on oxidative modification of lysosomal proteins of liver of intact sexually mature female rats of Wistar line. Methods. In the control groups in vitro incubation of isolated lysosomes in the isolation medium for 1, 2 and 4 hours was carried out. Experimental groups were incubated similarly in solutions of 5 mM L-Nω-nitroarginine methyl ester and 0.1 mM sodium nitroprusside. Protein oxidative modification was measured in sedimentary fraction according to R.L. Levine’s method in E.E. Dubinina’s modification. Reserve-adaptive capacity was calculated as the difference between total area under the curve of carbonyl derived proteins after metal-catalyzed oxidation (taken as 100%) and spontaneous oxidation, expressed as a percentage. Results. After 4-hour in vitro incubation 5 mM L-Nω-nitroarginine methyl ester was found to statically significantly increase the total level of protein oxidative modification compared to the control group by 2.41 times and to reduce reserve-adaptive capacity by 4.96 times, and 0.1 mM sodium nitroprusside increases the total level of protein oxidative modification compared to the control group by 2.05 times and reduces reserve-adaptive capacity by 1.56 times. One of the possible mechanisms of this phenomenon may be the reduced activity of lysosomal proteinases. 2-hour and 4-hour in vitro incubation of lysosomes in 5 mM L-Nω-nitroarginine methyl ester is accompanied by an increase of secondary markers of the ratio of protein oxidative modification relatively to 1-hour exposure by 1.18 times and 1.35 times, respectively. At 1-hour in vitro incubation in 0.1 mM sodium nitroprusside, increase of secondary markers of protein oxidative degradation by 1.64 times occurs. Conclusion. The in vitro effect of 5 mM -Nω-nitroarginine methyl ester and 0.1 mM sodium nitroprusside results in visible changes of oxidative modification of rat liver lysosomal proteins.

 Aim. The study of the prevalence and clinical peculiarities of Mycoplasmosis and Chlamydiosis in patients with different pathogenic forms of bronchial asthma (BA) taking into account ethnicity of a patient. Subjects and Methods. The research covered 239 subjects – both the Europeoids and the Mongoloids in the city of Krasnoyarsk and the town of Kyzyl, all of them being BA patients of different stages, including acute stage and practically healthy. We had determined antigens Mycoplasma pneumoniae, Mycoplasma hominis, Chlamydophila pneumoniae, Chlamydophila psittaci and Chlamydia trachomatis in smears of mucosa of pharynx and antibodies to these antigens in peripheral blood serum. Results.  We found high frequency of Mycoplasmosis and Chlamydiosis in the inhabitants of Eastern Siberia, BA patients with different pathogenic forms as compared to control group. We had determined ethnic peculiarities of specific immune response: IgM to М. pneumoniae was revealed in the Europoids more frequently than in the Mongoloids, but IgM to С. pneumoniae and to C. trachomatis, C. trachomatis antigens had been revealed more often in the Mongoloids than in the Europoids. We accepted as clinical equivalents of Mycoplasmosis and Chlamydiosis diagnostics the following signs: temperature around 37C (subfebrile temperature), non-intensive but stable coughing with scanty mucous and muco-purulent sputum, dyspnea of mixed character. Conclusions. Mycoplasma and Chlamydia are meaningful etiologic factors of bronchial asthma. We have found the peculiarities of immune response depending on ethnicity of a patient (ethnic belonging). Clinical markers of Mycoplasmosis and Chlamydiosis should be taken into account in bronchial asthma in order to provide diagnostics timely as well as eradication of infection agents. Because of insufficient knowledge of problem of bronchial asthma related to contamination with Мycoplasma and Chlamydia we put the goal to study the frequency of Mycoplasmosis and Chlamydiosis occurrence in bronchial asthma patients and determine the characteristics clinical course of diseases. We defined antigens Мycoplasma pneumoniae, Мycoplasma hominis, Chlamydophila pneumoniaе, Chlamydophila psittaci, Chlamydia trachomatis in smears of oropharynx mucosa and antibodies to them in blood serum.

To evaluate possibilities of aspirin-induced gastroduodenopathy treatment in the patients with chronic ischemic heart disease by means of applying the internal endogenous prostaglandins stimulant.  Material and methods. 340 patients suffering from chronic coronary heart disease and receiving a long-term acetylsalicylic acid (ASA) therapy were examined on the base of the cardiovascular care unit of The Nizhny Novgorod Regional Clinical Hospital named after N.A. Semaschko. There were evaluated frequency, nature and severity of the aspirin-induced gastroduodenopathy. The patients with coronary heart disease and aspirin-induced gastroduodenopathy were divided in two groups. In the first group of patients there was applied rebamipide therapy (in a single daily dose 300 mg) in combination with the proton pump inhibitor (PPI) — pantoprazole. In the second group there was applied only pantoprazole therapy. For the purpose of specification of AIG pathogenetic mechanisms development, all the examined chronic coronary heart disease cases were tested on the prostaglandin E2 (PGE2) level in blood serum before the therapy beginning and after the treatment. The control group was formed of chronic coronary heart disease patients showing no AIG evidence. Statistical processing of the received data was fulfilled with the program «Statistika 10.0». Results. AIG was registered in 15% out of 340 chronic coronary heart disease patients. According to the endoscopic examination erosive disease of the body and antrum prevailed among the patients. The PGE2 level in the blood serum was significantly lower (р = 0,00087) in these patients in comparison with the control group. In association with PPI and rebamipide mixed therapy, esophagogastroduodenoscopy results showed no pathological findings in gastrointestinal mucosa and statistically significant (р = 0,00067) blood serum PGE2 level growing in all the treated patients. As a result of exclusive PPI therapy there was marked positive dynamics in endoscopic view in 19 out of 25 patients and a tendency to normalization of PGE2 level in the blood serum. However, PGE2 level growing was insignificant. Conclusion. The presented research demonstrates the possibility of AIG treatment with the use of internal endogenous prostaglandins stimulant — rebamipide in complex with proton pump inhibitor PPI therapy.

Introduction. The overwhelming number of publications contains only data on the content of individual antioxidants, but not on the overall antioxidant activity of the blood in patients with vibration disease.The aim of the study was to determine the total antioxidant activity of blood serum in patients with vibration disease.Materials and methods. Th e main group consisted of 30 people diagnosed with “Vibration disease” of 1 degree (n=21) and 2 degrees (n=9). Th e control group consisted of 30 clinically healthy men, comparable in age with the main group (p=0.66). Th e total activity of antioxidant systems of blood plasma was evaluated photometrically using the test system “Total antioxidant status-Novo” (“Vector-best”, Russia).Results. The indicator of the total antioxidant status (TAS) was 1,038±0.232 mmol/l in the examined main group, against 1,456±0.225 mmol/l in the examined control group (p<0.000001). Th e coefficient of variation (CV) in patients with vibration disease was 22.35%, 1.45 times higher than in the control group (15.45%). In the main group there was a positive correlation between age and TAS (R=0.525), in the control group there was no such relationship (R=0.095). Th e degree of decrease depended on the severity of vibration disease.Conclusions. 1. The development of vibration disease is accompanied by a decrease in the antioxidant status of blood serum. 2. Th e degree of decrease in the antioxidant status of blood serum correlates with the severity of vibration disease. 3. Reduction of TAS can serve as a pathogenetic justification of the need to include drugs and/or biologically active additives with antioxidant activity in therapy
