    Currently, hemorrhagic fever with renal syndrome (HFRS) remains the most common natural focal disease of viral etiology in the Russian Federation. Effective antiviral drugs have not yet been developed. Pathogenetic and symptomatic drugs are mainly used in the treatment of HFRS.The aim of the study was to evaluate the clinical and laboratory effectiveness of intravenous gabriglobin in the treatment of moderate forms of HFRS.Materials and methods. The study included 22 patients with a diagnosis β€œHFRS of moderate severity” in the febrile stage of the disease. In the febrile period of HFRS, patients of the main group (n=10) were given gabriglobin via intravenous route at a dose of 0.1 g/kg per day along with pathogenetic therapy. The course of treatment was 2–3 infusions. The control group (n=12) received only pathogenetic therapy.Results and conclusions. As a result of the studies, the clinical and laboratory efficacy of intravenous administration of gabriglobin in the treatment of patients with moderate-grade HFRS was revealed, which was manifested by a decrease in the duration of the febrile period by 2.1 days, the severity of oliguria and a decrease in the duration of thrombocytopenia by 3.5 days compared with the group of patients receiving only pathogenetic therapy

    The results of treatment of data obtained in the SERP-E-184experiment "Investigation of mechanisms of the production of charmed particles in proton-nucleus interactions at 70 GeV and their decays" by irradiating the active target of the SVD-2 facility consisting of carbon, silicon, and lead plates, are presented. After separating a signal from the two-particle decay of neutral charmed mesons and estimating the cross section for charm production at a threshold energy {\sigma}(c\v{c})=7.1 \pm 2.4(stat.) \pm 1.4(syst.) \mub/nucleon, some properties of D mesons are investigated. These include the dependence of the cross section on the target mass number (its A dependence); the behavior of the differential cross sections d{\sigma}/dpt2 and d{\sigma}/dxF; and the dependence of the parameter {\alpha} on the kinematical variables xF, pt2, and plab. The experimental results in question are compared with predictions obtained on the basis of the FRITIOF7.02 code.Comment: 9 pages, 9 figures,3 table

    Observation of narrow baryon resonance decaying into pKs0pK^0_s in pA-interactions at 70GeV/c70 GeV/c with SVD-2 setup

    Full text link
    SVD-2 experiment data have been analyzed to search for an exotic baryon state, the Θ+\Theta^+-baryon, in a pKs0pK^0_s decay mode at 70GeV/c70 GeV/c on IHEP accelerator. The reaction pAβ†’pKs0+XpA \to pK^0_s+X with a limited multiplicity was used in the analysis. The pKs0pK^0_s invariant mass spectrum shows a resonant structure with M=1526Β±3(stat.)Β±3(syst.)MeV/c2M=1526\pm3(stat.)\pm 3(syst.) MeV/c^2 and Ξ“<24MeV/c2\Gamma < 24 MeV/c^2. The statistical significance of this peak was estimated to be of 5.6Οƒ5.6 \sigma. The mass and width of the resonance is compatible with the recently reported Θ+\Theta^+- baryon with positive strangeness which was predicted as an exotic pentaquark (uuddsΛ‰uudd\bar{s}) baryon state. The total cross section for Θ+\Theta^+ production in pN-interactions for XFβ‰₯0X_F\ge 0 was estimated to be (30Γ·120)ΞΌb(30\div120) \mu b and no essential deviation from A-dependence for inelastic events (∼A0.7)(\sim A^{0.7}) was found.Comment: 8 pages, 7 figures, To be submitted to Yadernaya Fizika. v3-v5 - Some references added, minor typos correcte

    Charged vector Dβˆ—+(2010)D^{*+}(2010) meson production is studied in a high energy neutrino bubble chamber experiment with mean neutrino energy of 141 GeV. The Dβˆ—+D^{*+} are produced in (5.6Β±1.8)%(5.6 \pm 1.8)\% of the neutrino charged current interactions, indicating a steep increase of cross section with energy. The mean fractional hadronic energy of the Dβˆ—+D^{*+} meson is 0.55Β±0.060.55 \pm 0.06

    Objective. The aim of the study is to develop a technique of potentiating traditional multimodal anesthesia with contact laser exposure to the body in the red range (650 nm) in patients with critical lower limb ischemia (CLI).Materials and methods. Multimodal anesthesia in the main group was performed with the potentiation of modern laser technology in 70 to 94 years old 35 patients [7 (20.0 %) women and 28 (80.0 %) men] with CLI and associated diseases. As a comparison group, a retrospective group of 23 patients was selected who underwent a high amputation of the lower extremities without potentiation of multimodal anesthesia with laser blood radiation. Multimodal anesthesia was additionally potentiated with quantum hemotherapy sessions. Sessions were carried out using a fifth-generation semiconductor contact laser irradiation of blood LASPOT (PRC) in the form of a wristwatch with an additional effect on the acupuncture points Nei-Guan, Tun-li – the heart meridian, connection with the inner world, Ling-dao – the meridian hearts, the road of the spirit. The first session was performed to patients before surgery β€” a duration of 15 minutes; the second β€” during surgery β€” a duration of 30 minutes.Results. The obtained data on the shifts of peripheral hemodynamic parameters at the stages of surgical interventions in patients of both groups practically did not demonstrate significant differences from the baseline values, reflecting the adequacy of the degree of anesthesiological protection. In patients of the main group, central hemodynamic indices: the cardiac index (CI) significantly increased from 2.81 Β± 0.49 to 3.15 Β± 0.58 (p &lt; 0.05) l/minβˆ™m2, and total peripheral vascular resistance (TPVR) decreased from 1587.5 Β± 494.3 to 1492.7 Β± 427.8 dynβˆ™sβˆ™cm-5. In patients of the comparison group, CI increased during surgery from 2.83 Β± 0.53 to 3.02 Β± 0.35 l/minβˆ™m2, and at the end of the operation it returned to baseline. Potentiation of multimodal anesthesia with modern laser technologies in patients of the main group made it possible to reduce during surgical interventions the average dose of fentanyl, which was 0.98 Β± 0.12 mcg/kg/h, while in patients of the comparison group, the consumption of fentanyl was 3.28 Β± 0.18 mcg/kg/h (with traditional combined general anesthesia, the flow rate of fentanyl during surgery is on average 5–12 mcg/kg/h or more).Conclusion. The method of potentiation of the traditional scheme of general combined anesthesia with optical radiation of the red range (650 nm) allows to achieve more pronounced effects of hemodynamic control, makes it possible to reduce the dose of fentanyl, reduce the pharmacological load on the operated patient.ЦСль исслСдования: Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚Π°Ρ‚ΡŒ ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΡƒ потСнцирования Ρ‚Ρ€Π°Π΄ΠΈΡ†ΠΈΠΎΠ½Π½ΠΎΠΉ ΠΌΡƒΠ»ΡŒΡ‚ΠΈΠΌΠΎΠ΄Π°Π»ΡŒΠ½ΠΎΠΉ анСстСзии ΠΊΠΎΠ½Ρ‚Π°ΠΊΡ‚Π½Ρ‹ΠΌ Π»Π°Π·Π΅Ρ€Π½Ρ‹ΠΌ воздСйствиСм Π½Π° ΠΎΡ€Π³Π°Π½ΠΈΠ·ΠΌ Π² области красного Π΄ΠΈΠ°ΠΏΠ°Π·ΠΎΠ½Π° дСйствия (650 Π½ΠΌ) Ρƒ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² с критичСской ишСмиСй Π½ΠΈΠΆΠ½ΠΈΡ… конСчностСй (КИНК).
