Functional Phenotype of Alveolar Macrophages Features in Rats with Metabolic Syndrome.

Phenotypic characteristics of alveolar macrophages in the bronchoalveolar lavage fluid as well as their ability to acquire the M1 and M2 phenotypes during in vitro culturing with reprogramming factors were studied in rats with modeled diet-induced metabolic syndrome. A decrease in the number of alveolar macrophages with the M1 phenotype was found in animals with metabolic syndrome. The factors of metabolic syndrome do not affect phenotypic plasticity of cells in culture, but under the action of M2 reprogramming factors, the cells demonstrate a wide range of phenotypic plasticity by the CD80 and CD206 markers.

Analysis of metal content in soils near abandoned mines of Bashkir Trans-Urals and in the hair of children living in this territory.

The aim of this study was to investigate the metal content in the hair of children living near abandoned nonferrous metal mines located in the rural settlements Tubinsk, Ishmurzino and Semenovsk the South Urals (Russia), and in the soils obtained from the same area. The hair and soils samples were examined for the presence of the following metals: copper (Cu), zinc (Zn), iron (Fe), cobalt (Co), nickel (Ni), manganese (Mn), lead (Pb) and cadmium (Cd). The results of this study showed that soil from this territory contained an increased level of Cu, Fe, Zn, Mn, Pb, Cd, exceeding the maximum permissible concentration (MPC) 38.

[Analysis of the state-of-the-art of consulting medical care to patients with glucocorticoid-induced osteoporosis or its risk according to the data of a questionnaire survey (GLUCOST study)].

Aim: To analyze the state-of-the-art of consulting medical care to Russian patients with glucocorticoid-induced osteoporosis (GCOP) or its risk.

Subjects And Methods: This GLUCOST study was organized and conducted by the Russian Association of Osteoporosis. A total of 1129 patients with chronic inflammatory diseases, who had been taking oral glucocorticosteroids (OGCSs) a long time (3 months or more), were examined.

[Modulatory effect of isoniazid and rifampicin in vitro on cytokine secretion in pulmonary tuberculosis].

The effects of isoniazid and rifampicin on the peripheral mononuclear production of IL-2, IL-12, IL-10, IFN-gamma, and TGF-beta were evaluated in patients with infiltrative pulmonary tuberculosis. Irrespective of the susceptibility of the causative agent to the essential antituberculous drugs, rifampicin was ascertained to initiate increased IL-2 secretion and to reduce the generation of IL-12, IFN-gamma and TGF-beta. Isoniazid suppressed the mononuclear leukocytic production of IFN-gamma in drug-sensitive pulmonary tuberculosis, and conversely, stimulated it in the drug-resistant type.

[The molecular-genetic aspects of tubercular infection forecasting and immunotherapy].

In article is presented, the analysis of the data of the literature and own researches, concerning molecular-genetic mechanisms of antimycobacterial immunity infringements. The role of the factors defining features of a current and an outcome of a tubercular infection, namely of immunity system condition, feature of infecting microbic Mycobacterium tuberculosis strain biological properties (a genotype, a spectrum of drag sensitivity/resistance), influence of combined antitubercular chemotherapy is disc issed. The opinion is expressed that the given factors are necessary for taking into consideration for working out methodology the personalised preventive maintenance and correction of immunity infringements during pulmonary tuberculosis.
