The first half of the XXI-st century is characterized by increasing in the incidence of fungal infections. A wide range of spatial spreading of fungal infections, including dermatophytes and vaginal candidiasis (thrush), which can be explained by intensive migration and changing lifestyles in industrialized countries. This growth was not stopped after the introduction of new antifungal pharmaceuticals, most of which have side effects and are characterized by significant toxicity. In this regard, remains perspective development of new effective non-toxic natural antifungal drugs. Objective. The study of some potential mechanisms of domestic antimycotic Esulanum such as spectrum antimicrobial activity against gram-positive, gram-negative bacteria, microscopic fungi and yeast; influence on morphological characteristics and enzymatic activity of yeast. Methods. The study of antimicrobial activities was performed by preparation of serial dilutions. Study of the dynamics of cell death under the influence of Esulanum performed on models of culture Candida tropicalis. Cell morphology was studied using a light microscope. Results. It was shown that the Esulanum has a broad-spectrum activity against gram-positive and gram-negative bacteria, yeasts and fungies. Minimum inhibitory concentration of Esulanum against yeast (250-500 ug/ml), fungi (62,5-500 ug/ml) gram-positive (31,2-250 ug/ml) and gram-negative (62,5-250 ug/ml) bacteria was established. The study of morphological character of Candida tropicalis cells showed that the introduction of Esulanum into the culture medium in the fungicidal concentration led to changes in the morphogenesis of yeast cells, the degree of manifestation of which was due to a temporary agent. The appearance under the influence of the drug bumps and disruptions on the surface of yeast cells, as well as change their shape was probably due to a breach of the normal metabolism of culture, which was confirmed by the experimental data. Conclusions. The results indicate that Esulanum is a broad-spectrum drug, active not only in relation to micromycetes and yeast cultures, but also Gram-positive and Gram-negative bacteria. It was found that Esulanum affects the metabolic processes of the fungal cells. During the preclinical studies further research should be aimed at the study of the mechanism of action of the drug on cells of fungal cultures.ΠŸΡ€ΠΎΠ±Π»Π΅ΠΌΠ°Ρ‚ΠΈΠΊΠ°.

    At present, development of effective vaccines of new generation is an actual problem, in particular concerning the tularemia causative agent. It determines the need to search antigen determinants with high immunogenic activity. Some authors demonstrate that outer membrane proteins of Francisella tularensis possess immunological activity. This fact gave occasion to isolation and comprehensive study of F tularensis cellular envelopes as a perspective component in vaccine engineering. The influence of cell walls of F. tularensis was studied for morphological changes in immunocompetent organs of experimental animals. Cell walls were obtained from three virulence strains of living cultures: F. tularensis subsp. mediaasiatica А-61, F. tularensis subsp. nearctica Π’-399 A-Cole, F. tularensis subsp. holarctica 306 and vaccine strain F. tularensis subsp. holarctica 15 (extracted by Research Institute of Epidemiology and Hygiene). Cell walls of different subspecies of F. tularensis stimulate the production of antibody forming cells and cell proliferation more in T-dependent zones of lymph nodes and spleen. It has been determined that these antigen preparations do not cause stress reaction of the experimental animal organisms. Basing on the findings, we made a conclusion that there is a need for further detailed investigation of immunogenic properties of CE F. tularensis subsp. holarctica 306, F. tularensis subsp. mediasiatica А-61 and F. tularensis subsp. tularensis B-399 A-Cole as perspective components in development of tularemia vaccines

    Scleroderma systematica (SDS) is a disease in which vascular diseases underlie the pathogenesis and presented by diverse clinical manifestations. Raynaud's syndrome and digital ulceration are the most common symptom of the diseases, which influences the quality of life in patients and requires continuous drug therapy. The paper discusses the recent European guidelines for the management of this manifestation of SDS. The proposed recommendations cannot unfortunately be realized in full measure now due to the unavailability of some drugs.

    Live vaccines are used for specific brucellosis prophylaxis in the Russian Federation. These vaccines in addition toΒ a number ofΒ  positive properties have some limitations including highΒ  agglutinogenicity, reactogenicity, sensitizingΒ activity. In thisΒ  connection, the development of subunit vaccines without adverseΒ  reactions is a perspective directionΒ in modern vaccinology.Β ComplexΒ  morphological research of the adrenal glands and comparativeΒ  analysis of peripheral blood (leukogram, leukocyticΒ index and indexΒ  of allergization) of white mice immunized with thermoextracts (Π’E)Β  of Brucella abortus I-206 inΒ L- and S-form and inactivated vaccine B.Β  abortus 19 ВА were conducted. It was shown that Π’E unlike B.Β  abortus 19 ВА caused minor alterations in peripheral blood of theΒ  experimental animals in early periods of observation (increase ofΒ allergization index, changes in leukogram) with the subsequentΒ  levelling to the values in control.Β Expositions of the adrenal glandΒ  zoning were determined and cellular structure was estimated inΒ  consideration ofΒ morphometry. Changes in architectonics of the miceΒ  organ immunized with B. abortus 19 ВА were revealed. TheseΒ alterations could indicate the stress-reaction development. InΒ  case of Π’E application the given changes were insignificantΒ and wereΒ  developed in early periods.Β The revealed morphological changes inΒ  adrenal glands of laboratory animals permit to prove the necessity ofΒ  realizationΒ the further experimental researches to Π’E applicationΒ  as the components for development of a subcellular brucellosisΒ vaccine

    Objective. To compare disease history data and clinical and laboratory parameters in patients with scleroderma systematica (SDS) with high-resolution computed tomography (HRCT)-verified interstitial lung lesion (ILL) versus those without lung involvement. Subjects and methods. An examination was made in 138 patients with SDS who had been consecutively admitted in 2006-2008, female/male ratio, 124 : 14; limited : diffuse : mixed forms, 78 : 40 : 20; mean age, 47Β±13 years; median disease duration, 6 (2.5 11) years. The history data (occupational hazards, smoking, respiratory diseases) and clinical manifestations of SDS and laboratory data were studied. The diagnosis of ILL was established on the basis of chest HRCT. Results. According to HRCT data, the signs of varying ILL were found in 82% of the patients with SDS. The duration of SDS was similar in the patients with and without lung involvement; but the latter were younger at the time of disease onset. There were no significant differences between the groups compared in history data, clinical forms of SDS, the frequency of involvement of visceral organs and systems. Crepitation was heard only in the patients with ILL. The frequency of respiratory manifestations increased with a larger number of the involved lung segments. The prevalence of ILL was found to be positively correlated with age at the onset of SDS (r=0.29;

    Radioisotope Products and the Medicine of the Future: an IAEA Perspective

    Get PDF
    The production and application of radioisotopes and radiopharmaceuticals is a major peaceful application of nuclear science and technology and has opened new gateways for nuclear medicine in critical human diseases. Advances in the production of radioisotopes via nuclear reactors, accelerators, fission, etc. has facilitated the access to these products for Member States. 99Mo, 131I, 177Lu are among the most essential radioisotopes for nuclear medicine and human health and their production and availability always has been an important theme for professional societies and the International Atomic Energy Agency (IAEA). In the meantime, a large list of theranostic radioisotopes including but not limited to 89Zr, 68Ga, 225Ac, Cu-series, Sc-series, Tb-series etc. has provided a powerful toolbox for clinicians and the IAEA is taking steps to ensure their safe and appropriate application in radiopharmacy. The Agency promotes the production and application routes, including research reactors, cyclotrons, linear accelerators, and other cutting-edge methods, according to international and national guidelines and regulations. The IAEA also conducts activities such as Coordinated Research Projects (CRPs), Technical Meetings (TMs), national/regional training courses and conferences, to support and join forces with international professional societies in the development of human resources and research and development activities. Development of databases and freely available publications for all Member States are other useful means to support Member States in radiopharmaceutical sciences
