    Authors investigate cells and immunologic factors of induced sputum in children with newly diagnosed asthma and healthy children without atopy. The aim of the study was to find out the differences of cellular and immunologic profiles of induced sputum in children with newly diagnosed asthma. 35 children aged 1,5-5 years old (Me = 3,5 years) were include in this study: 18 children with newly diagnosed asthma and 17 children (control group) without allergic diseases, which had no respiratory symptoms during last month. Sputum induction carried out according to our modification of protocol developed by Pin et al. The levels of IgE, slgA, lgG4, IL-1Ξ², IL-4, IL-8, IL-13, TNFΞ±, INFΞ³, N03, NOX and cells percentage (macrophages, neutrophils, eosinophils, lymphocytes) were evaluated in sputum. Results. The percentage of eosinophils was significantly higher and the percentage of macrophages was significantly lower in induced sputum of children with newly diagnosed asthma. The levels of proinflammatory factors (IL-1Ξ², IL-4, IL-8, IL-13, TNFΞ±), immunoglobulins, which participate in allergic inflammation (IgE, slgA, lgG4) and stable metabolites of NO (NO3, NOX) in sputum were also significantly higher in children with newly diagnosed asthma.ΠŸΡ€ΠΎΠ²ΠΎΠ΄ΠΈΠ»ΡΡ подсчСт ΠΊΠ»Π΅Ρ‚ΠΎΠΊ ΠΈ ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ иммунологичСских Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² Π² ΠΈΠ½Π΄ΡƒΡ†ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠΉ ΠΌΠΎΠΊΡ€ΠΎΡ‚Π΅ Ρƒ Π΄Π΅Ρ‚Π΅ΠΉ с впСрсыС выявлСнной Π±Ρ€ΠΎΠ½Ρ…ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ астмой ΠΈ Π·Π΄ΠΎΡ€ΠΎΠ²Ρ‹Ρ… Π΄Π΅Ρ‚Π΅ΠΉ Π±Π΅Π· Π°Ρ‚ΠΎΠΏΠΈΠΈ.

    A prospective cohort study was conducted to assess the effect of a recombinant interferon alpha-2b prophylactic course on cyto-immunological parameters of induced sputum in children with mild asthma, the main trigger of exacerbation of which was respiratory viral infections.We examined 40 children aged 1 to 7 years with (mean age β€” 4.8 Β± 0.2 years), half of whom received a course of recombinant interferon alpha-2b. The authors detected respiratory viruses in scrapings from throat and nose (PCR method) and evaluated the different cell counts, also the levels of interleukin-10, tumor necrosis factor alpha, interferon alpha and immunoglobulin E on the 1st and 30th day of the study (ELISA method) were determined in sputum.The number of asthma exacerbations, triggered by respiratory viral infection, decreased in 4.5 times against. In children who received recombinant interferon alpha-2b the count of sputum eosinophils and the number of children with sputum eosinophilia (β‰₯3 %) reduced. After two months the level of nasal eosinophils was 30% lower than the start level. The level of IgE in induced sputum decreased by 35%, but the level of IL-10 was increased by 1.5 times. 75% of parents whose children received recombinant interferon alpha-2b, note positive effect of this drug.There were no adverse events to receive the drug in any case. Thus, the use of recombinant interferon alpha-2b in children with virus-induced asthma to reduce episodes of exacerbations associated with acute respiratory diseases can be recommended.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ΠΎ проспСктивноС ΠΊΠΎΠ³ΠΎΡ€Ρ‚Π½ΠΎΠ΅ исслСдованиС с Ρ†Π΅Π»ΡŒΡŽ ΠΎΡ†Π΅Π½ΠΊΠΈ влияния профилактичСского курса Ρ€Π΅ΠΊΠΎΠΌΠ±ΠΈΠ½Π°Π½Ρ‚Π½ΠΎΠ³ΠΎ ΠΈΠ½Ρ‚Π΅Ρ€Ρ„Π΅Ρ€ΠΎΠ½Π° Π°Π»ΡŒΡ„Π°-2b (суппозитории ΠΈ гСль) Π½Π° клиничСскоС Ρ‚Π΅Ρ‡Π΅Π½ΠΈΠ΅ ΠΈ цитоиммунологичСскиС ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»ΠΈ ΠΈΠ½Π΄ΡƒΡ†ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠΉ ΠΌΠΎΠΊΡ€ΠΎΡ‚Ρ‹ Ρƒ Π΄Π΅Ρ‚Π΅ΠΉ с Π»Π΅Π³ΠΊΠΎΠΉ Π±Ρ€ΠΎΠ½Ρ…ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ астмой, основным Ρ‚Ρ€ΠΈΠ³Π³Π΅Ρ€ΠΎΠΌ обострСния ΠΊΠΎΡ‚ΠΎΡ€ΠΎΠΉ являлись острыС рСспираторныС вирусныС ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ.Π’ исслСдованиС Π±Ρ‹Π»ΠΎ Π²ΠΊΠ»ΡŽΡ‡Π΅Π½ΠΎ 40 Π΄Π΅Ρ‚Π΅ΠΉ Π² возрастС ΠΎΡ‚ 1 Π΄ΠΎ 7 Π»Π΅Ρ‚ (срСдний возраст β€” 4,8 Β± 0,2 Π»Π΅Ρ‚), ΠΏΠΎΠ»ΠΎΠ²ΠΈΠ½Π° ΠΈΠ· ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Ρ… ΠΏΠΎΠ»ΡƒΡ‡Π°Π»ΠΈ курс Ρ€Π΅ΠΊΠΎΠΌΠ±ΠΈΠ½Π°Π½Ρ‚Π½ΠΎΠ³ΠΎ ΠΈΠ½Ρ‚Π΅Ρ€Ρ„Π΅Ρ€ΠΎΠ½Π° Π°Π»ΡŒΡ„Π°-2b ΠΏΠΎ схСмС Π² Ρ‚Π΅Ρ‡Π΅Π½ΠΈΠ΅ 29 Π΄Π½Π΅ΠΉ.

    H1 NMR relaxometry is a method that is extremely sensitive to the presence of magnetic nanoparticles, which significantly affect the transverse relaxation time of the water proton. Accordingly, the use of magnetic nanoparticles as labels allows detection of even extremely small amounts of the test substance. This paper analyzes the prospects for applying the method of solid-phase NMR-relaxometric determination of biologically active molecules. The nitrocellulose membranes are chosen as a solid phase and nanoparticles based on iron core with a carbon shell are used as magnetic labels. The possibility of detecting small concentrations of magnetic particles in porous medium is demonstrated. Finally, the ability to detect extremely low concentrations of an analyte, in this case, streptavidin protein (0.5 ng/ml to 100 ng/ml), which is actively used in various fields of biology and medicine, is demonstrated.
