Применение препарата Дипроспан в послеоперационном периоде у больных полипозным риносинуситом

Diprospan (betametason disodium phosphate plus betametason dipropionat) endonasal injection efficiency rating was carried out. Diprospan postoperative endonasal injection methodolody is described. In this research we compared nasal mucosa renewal in two patient groups. At first group (25 patients) we used endonasal Diprospan injection after operation, in second group (25 patients) - we didn't. Postoperative Diprospan endonasal injection makes mucosa recovery process faster.Произведена оценка эффективности эндоназального введения препарата Дипроспан (бетаметазона динатрия фосфат и бетаметазона дипропионат) по разработанной нами методике после хирургического вмешательства у 25 больных в сравнении с группой из 25 больных, которым проводилось только хирургическое вмешательство. Применение препарата Дипроспан после хирургического вмешательства по разработанной ними методике способствовало более раннему восстановлению дыхательной функции носа

Study of KS KL Coupled Decays and KL -Be Interactions with the CMD-2 Detector at VEPP-2M Collider

The integrated luminosity about 4000 inverse nanobarn of around phi meson mass ( 5 millions of phi mesons) has been collected with the CMD-2 detector at the VEPP-2M collider. A latest analysis of the KS KL coupled decays based on 30 % of available data is presented in this paper. The KS KL pairs from phi meson decays were reconstructed in the drift chamber when both kaons decayed into two charged particles. From a sample of 1423 coupled decays a selection of candidates to the CP violating KL into pi+ pi- decay was performed. CP violating decays were not identified because of the domination of events with a KL regenerating at the Be beam pipe into KS and a background from KL semileptonic decays. The regeneration cross section of 110 MeV/c KL mesons was found to be 53 +- 17 mb in agreement with theoretical expectations. The angular distribution of KS mesons after regeneration and the total cross section of KL for Be have been measured.Comment: 14 pages, 8 figure

Diagnostics of plasma streams and plasma-surface interaction of essentially different duration of plasma pulses

Studies of main characteristics of the plasma streams generated by magneto-plasma compressor (MPC) and quasi-stationary plasma accelerator QSPA Kh-50 have been performed. Main features of Plasma Surface Interaction (PSI) have been researched in dependence on plasma heat loads, plasma density and pulses duration. QSPA Kh-50 creates long pulse plasma streams (pulse length of 0.25 ms) with heat load on exposed surfaces of (0.45…0.75) MJ/m² . The MPC generates short (duration of 10…20 μs) compressed plasma streams with plasma density up to 10¹⁸ cm⁻³ , and plasma energy density of (0.05…0.5) MJ/m² . Performed studies of plasma-surface interaction include measurements of plasma energy deposited to the material surface as a function of the impacting energy and kind of targets. Temporal and spatial dependencies of electron density and temperature have been found. Special attention was paid to the dynamics of the spectral lines near surfaces of exposed targets.Изучены основные характеристики плазменных потоков, генерируемых магнитоплазменным компрессором (МПК) и квазистационарным плазменным ускорителем КСПУ Х-50.

Search for rare Phi decays in pi+ pi_ gamma final state

A search for phi radiative decays has been performed using a data sample of about 2.0 million phi decays collected by the CMD-2 detector at VEPP-2M collider in Novosibirsk. From the selected e+ e- -> pi+ pi- gamma events the following results were obtained: B(phi -> f0(980) gamma) < 1x10-4 for destructive and B(phi -> f0(980) gamma) < 7x10-4 for constructive interference with the Bremsstrahlung process respectively, B(phi -> gamma -> pi+ pi- gamma) 20 MeV, B(phi -> rho gamma) < 7x10-4. From the selected e+ e- -> mu+ mu- gamma events B(phi -> mu+ mu- gamma) = (2.3+-1.0)x10-5 has been obtained for E of gamma> 20 MeV. The upper limit on the P,CP-violating decay eta -> pi+ pi- has also been placed: B(eta -> pi+ pi-) < 9x10-4 . All upper limits are at 90 % C.L.Comment: 18 pages, 7 figure

The application of the lyophilized xenodermoimplants for the plastic correction of the external auditory canal and nasal septum perforation

The objective of the present work was to improve the effectiveness of the treatment of atresia of the external auditory canal (EAC). Atresia of external acoustic meatus is a result of a mechanical or thermal injury but can also develop after a surgical intervention for the removal of foreign bodies, benign and malignant tumours. This condition is frequently associated with the narrowing and obliteration of EAC leading to the marked impairment of hearing despite preservation of the middle ear structures. Plastic correction of the external auditory canal for the purpose of its broadening does not always produce the desired result. To improve the efficiency of such intervention, we made use of the lyophilized xenodermoimplants based on porcine skin. Such preparation were applied in 19 patients; patency of the external auditory canal was restored in 16 cases.Abstract available from the publisher
