Currently tuberculosis is considered as a group of diseases united by one etiological factor. The pathogenesis of certain localizations of tuberculous inflammation, in particular peritoneum tuberculosis, hasn’t been sufficiently studied. The role of cytokine mechanisms in the development of the disease and the elaboration of non-sterile immunity requires further experimental studies, in particular the creation of a reproducible model on laboratory animals.The aim: to study the effect of TNF-α on the development of tuberculosis of the serous coat of the abdominal cavity, as well as to evaluate the possibility of modeling tuberculous peritonitis in laboratory animals using infliximab.Materials and methods. The studies were conducted on 18 male rabbits, which were simulated peritoneal tuberculosis by intra-abdominal administration of a suspension of Mycobacterium tuberculosis. 10 rabbits of the experimental group were intravenously injected with an infliximab solution and an iron (III) hydroxide sucrose complex intraperitoneally a day before infection.Results. In the control group of animals, tuberculosis either didn’t develop, or in a third of cases it affected only the pulmonary parenchyma, while proliferative processes prevailed. On the contrary, in animals with inactivated TNF-α, in 100 % of observations, tuberculous peritonitis was detected with associated lung damage and the predominance of alterative caseous processes.Conclusion. The created model of tuberculous peritonitis shows the leading role of TNF-α in the activation of macrophages, as well as in attracting cells to the site of infection. This is the primary signal necessary for the formation and stability of granulomas since the neutralization of this cytokine leads to a loss of control over the infection and the destruction of the granuloma with the development of destructive tuberculosis in the serous coat of the abdominal cavity.

Introduction. For diseases such as stricture and obliteration of the urethra, urethral hypospadias, reconstructive operations are required. The buccal mucosa is the material most commonly used for these operations. The search for alternative materials, carried out in order to reduce trauma and complications in the donor area, is an urgent area of modern urology. Tissue engineered constructions (TEC) can be used as such material.Objective. Justification of the possibility of applying a TEC based on the biodegradable polymers and seeded with autologous buccal epithelium (BE) cells as an implantable material for urethroplasty in an experiment.Methods and Materials. TEC based on poly-L-lactide-caprolactone (PLC) and poly-L-lactide-glycolide (PLG) seeded with BCs was created. Rabbits (n=12) underwent a biopsy of the oral mucosa, BCs were isolated, cultured and PLC-PLG scaffold was seeded with cells. TECs seeded with autological BCs were used on the model of acute trauma of rabbit urethra for replacement urethroplasty.Results. The results were evaluated after 12 weeks, according to the histological examination, there was a repair of the urethral mucosa. According to the data of retrograde urethrography, no impaired urethra patency was detected.Conclusion. TEC (PLK-PLG) seeded with autologous BCs ensured the maintenance of the rabbit urethral lumen which is necessary for adequate urination. This TEC could be recommended for the further clinical studies.

Improving specific prevention of tuberculosis continues to be a top priority in phthisiology. “Prime-boost” vaccination schemes aim to maintain adequate levels of specific immunity while forming long-term protection. They are based on sequential use of BCG vaccine and new vaccine candidates expressing protective mycobacterial proteins. The development of new tuberculosis prevention approaches requires an understanding of how the anti-tuberculosis immune response forms and which mechanisms provide TB protection. Since tuberculosis is an airborne infection, vaccine effectiveness largely depends on mucosal immunity based on the formation of long-lived, functionally-active memory T-lymphocytes in the respiratory tract. We have previously shown that the influenza vector expressing ESAT-6 and Ag85A mycobacterial proteins (Flu/ESAT-6_Ag85A) in vaccination scheme of intranasal boost immunization resulted in significant increase of BCG's protective effect according to key indicators aggregate data in experimental tuberculosis infection. The aim of this work was to study the effect of intranasal immunization with the Flu/ESAT-6_Ag85A influenza vector on the formation of antigen-specific central and effector memory T cells and the cytokine-producing activity of effector T cells (TEM) in BCG standard and “BCG prime — influenza vector boost” vaccination schemes in mice. Intranasal immunization with the influenza vector has been shown to increase the proportion of antigen-specific CD4+ central memory T cells (TCM) in the pool of activated lymphocytes of lung and spleen reaching significant differences from the BCG group in the percentage of spleen CD4+ TCM (p < 0.01). In contrast to BCG, vaccination with the studied vaccine candidate was accompanied by accumulation of highly differentiated CD8 effector cells in lung, the target organ during tuberculosis infection. Comparative evaluation of the cell-mediated, post-vaccine immune response after immunization with influenzavector-based vaccine candidate (intranasal/mucosal) or BCG vaccine (subcutaneous) showed advantages in the mucosal group: in formation of functionally active subpopulations of effector CD4 and CD8 T lymphocytes (CD44highCD62Llow) in lungs secreting IL-2 as well as polyfunctional cells capable of coproducing two cytokines (IFNγ/TNFα or IFNγ/IL-2) or three cytokines (IFNγ/TNFα/IL-2). Due to their more pronounced effector function, polyfunctional T-lymphocytes can be considered to be potential immunological markers of protective immunity in tuberculosis.

The hepatoprotective activity of remaxol, reamberin and ademethionine was studied on a model of the liver Injury Induced by antituberculosis drugs. The study included 30 male uninbred albino rats. The following antituberculosis drugs were used: isoniazid (50 mg/kg) subcutaneously + rifampicin (250 mg/kg) intragastrically + pyrazinamide (45 mg/kg) intragastically (by the procedure of Yu.I. Slivka, 1989). Remaxol, reamberin and ademethionine were administered 1.5 hour prior to the antituberculosis drugs. The treatment course was 14 days. It was shown that remaxol, reamberin and ademethionin were able to correct the structural and functional disorders in the liver due to the use of the antituberculosis drugs. By the impact on the biochemical indices, evident of the liver function condition, remaxol showed the maximum effect. The effect of reamberin was somewhat lower and the results of the ademethionine use were less significant. Remaxol had also a distinct effect as for lowering the level of the structural injuries in the liver, evident from recovery of the organ histoarchitectonics, less extended carbohydrate, albuminous and fatty degeneration, more active intracellular regeneration. It was noted that ademethionine had an insignificant effect on necrobiosis. Moreover, there was once detected a large necrosis focus, evident of possible stimulation of the liver tissue alteration by the drug.

The efficacy of reamberin, remaxol, S-adenosyl-L-methionine (ademethionine) and 5% glucose solution was estimated in the treatment of patients with tuberculosis of the respiratory organs and drug hepatotoxicity signs confirmed by higher activity of liver indicative enzymes and nitrogen oxide levels. Remaxol showed a pronounced positive effect on the cytolytic syndrome signs, evident from lower activity of alanine aminotransferase and aspartate aminotransferase. At the same time ademethionine was superior to remaxol in the effect on the cholestatic signs and inferior in the effect on the cytolytic signs. By the effect on the activity of alanine aminotransferase and aspartate aminotransferase, reamberin was inferior to remaxol and superior to ademethionine, its effect on the cholestasis markers level vs. the other drugs being superior only to that of 5% glucose solution. As compared to reamberin, ademethionine and 5% glucose solution, remaxol promoted higher integral indices of the host antioxidant protection (total antioxidant capacity and total antioxidant status), that partially explained the drug pronounced hepatoprotective effect.

Efficacy of remaxol In complex chemotherapy of generalized drug resistant tuberculosis was studied on mice. Mycobacterium tuberculosis 5419 SPBNIIF isolated from a patient with freshey diagnosticated pulmonary tuberculosis resistant to isoniazid (10 mcg/ml), rifampicin (40 mcg/ml), streptomycin (10 mcg/ml) and ethionamide (30 mcg/ml) was used in the experiments. The main polychemotherapy included 4 antituberculosis drugs in the highest therapeutic doses: isoniazid, amikacin, ethambutol and tavanic, the treatment course was 8 weeks. Remaxol was administered in a dose of 25 ml/kg intraperitoneally 5 times a week (14 injections). Significant activating effect of remaxol on the tension of the lung tissue local immunity was revealed by changes in the granuloma cell composition (from mainly epitheliod to mainly lymphoid) and by more frequent large lymphohistiocytic infiltrates. The use of remaxol also greatly increased the absorptive and digestive activity of the peritoneal macrophages phagocytosis, inhibited in the process of the experimental tuberculosis development.

The paper sets forth the stages of design and introduction of the new Russian tuberculosis (TB) drug perchlozon registered in the Russian Federation in 2012. Based on the results of Phases I-III clinical trials, the authors evaluate the efficacy and safety of the agent and consider the adverse effects of its treatment for respiratory TB. The use of perchlozon as a component of combination therapy versus standard chemotherapy regimens significantly reduces abacillation time in pulmonary TB caused by its drug-resistant pathogen. In terms of the higher prevalence of TB induced by its pathogen resistant to many drugs (with multiple and broad-spectrum drug resistance), perchlozon is an essential drug that has antituberculous activity mainly against multidrug-resistant Mycobacterium tuberculosis strains and gives patients with the severest and epidemiologically poor form of TB the chance to recover.

The effect of Roncoleukin on the recovery of the bone tissue in plastic operational defects (autobone+OsteoSet-T) on the model of experimental tuberculous osteites in 36 rabbits caused by drug resistant clinical strains of M. tuberculosis was studied. It was conducted a comparative analysis of the results of applying of Roncoleukin (12,5 mg/kg, 5 injections, one every 3 days) with anti-tuberculosis treatment in pre-and post-operative period. Efficacy was assessed in 1 and 6 months of surgical intervention on the phagocytic activity of peritoneal macrophages, X-ray study of plastics area, histological study of bone tissue sections. It was found that the most effective use of Roncoleukin appeared in the postoperative period. The analysis showed that Roncoleukin helped to accelerate the restructuring of plastic material - OsteoSet-T, reducing the prevalence of specific foci of inflammation in the bone tissue and the disappearance of alternative necrotic component; the increase of osteogenesis intensity with the new bone beams formation., as well as the activation of hematopoesis in bone marrow. The intensification of reparative processes in the bone combined with a distinct activation of phagocytosis.

The prevalence of tuberculous peritonitis that has been observed in the recent decades is the result of lymphohematogenous spread of Mycobacterium tuberculosis (MBT) from lungs and other extrapulmonary sources. It is still unclear why certain organs and anatomical regions get involved in the inflammatory process during generalization of the tuberculosis infection. Why do some cases develop into peritoneal tuberculosis and other into kidney tuberculosis? Thus study aimed to investigate the pathogenesis of tuberculous peritonitis in a reproducible biological model. Tuberculous peritonitis was modeled in 18 rabbits (10 in the test group, 8 in control) by intraperitoneal inoculation of the MBT suspension. In order to suppress peritoneal macrophages and major cytokines, test group rabbits were injected with the TNFα inhibitor and iron (III) hydroxide sucrose complex before being infected, while control group rabbits received no immunosuppressive drugs. Autopsy of the control group animals revealed changes characteristic of pulmonary tuberculosis in 37.5% of cases, with no damage to other organs and systems registered. Conversely, test group rabbits had the signs of tuberculous peritonitis in their abdominal cavities. The results of this study suggest that it is the local immunity of an anatomical area that largely determines whether a secondary focus of extrapulmonary tuberculosis infection will develop there or not. For the peritoneum, a smaller pool of peritoneal macrophages and weaker cytokine production is a necessary and sufficient condition to have tuberculous peritonitis developing therein.

С учетом результатов клинических исследований I-III фазы оценены эффективность и безопасность препарата, рассмотрены нежелательные эффекты лечения туберкулеза (ТБ) органов дыхания. Перхлозон в составе комплексной терапии по сравнению со стандартными схемами химиотерапии достоверно сокращает сроки абациллирования при ТБ легких, вызванного устойчивым к лекарственным препаратам возбудителем. В условиях роста распространенности ТБ, вызванного возбудителем, устойчивым ко многим лекарственным препаратам ('с множественной и широкой лекарственной устойчивостью'), перхлозон является необходимым препаратом, который обладает выраженной противотуберкулезной активностью, прежде всего в отношении штаммов микобактерий, устойчивых к лекарственным препаратам, и дает шанс на выздоровление пациентам с наиболее тяжелой и эпидемиологически неблагоприятной формой ТБ.

The taxonomy of coccoid cyanobacteria, such as Chroococcidiopsis , Pleurocapsa , Chroococcus , Gloeothece , Gloeocapsa , Gloeocapsopsis , and the related recent genera Sinocapsa and Aliterella , can easily be intermixed when solely compared on a morphological basis. There is still little support on the taxonomic position of some of the addressed genera, as genetic information is available only for a fraction of species that have been described solely on morphology. Modern polyphasic approaches that combine classic morphological investigations with DNA-based molecular analyses and the evaluation of ecological properties can disentangle these easily confusable unicellular genera. By using such an approach, we present here the formal description of two novel unicellular cyanobacterial species that inhabit the Coastal Range of the Atacama Desert, Gloeocapsopsis dulcis (first reported as Gloeocapsopsis AAB1) and Gloeocapsopsis diffluens. Both species could be clearly separated from previously reported species by 16S rRNA and 16S–23S ITS gene sequencing, the resulting secondary structures, p-distance analyses of the 16S–23S ITS, and morphology. For avoiding further confusions emendation of the genus Gloeocapsopsis as well as epitypification of the type species Gloeocapsopsis crepidinum based on the strain LEGE06123 were conducted.

The development of potential abilities and capabilities of the person in his/her adolescence is one of the important directions in the activities of contemporary psychologists-practitioners. A characteristic feature of this paper is the integration of psychological and pedagogical approaches to the analysis of the background foundations for the development of innovativeness and creativity in a personality in the educational environment of high school. The aim of the present work is to develop the technology of formation and realization of innovative potential of a personality basing on the empirical data. The study analyzed the qualitative and quantitative characteristics of the peculiarities of the innovation and creativity manifested by 13-14 and 16-18 year old students. The study is based on the following methods: 1) Creativity test composed by N. V. Vishnyakova; 2) "Selfevaluation scale devoted to innovative qualities" by N. M. Lebedev, A. N. Tatarko; 3) the method of "Personal readiness for changes" developed by Canadian scientists Rodnik, Heather, Gold and Hal. The authors used nonparametric U-criterion by Mann-Whitney and Spearman rank correlation coefficient as the main mathematical methods of research. Interpretation of the numerous data suggests that there are significant differences in the characteristics of creativity and innovativeness manifestation among students of different ages. Based on these data, the paper presents recommendations for the improvement of psycho-pedagogical technologies of supporting the formation of innovative potential of personality in high school.
