The indicators of optical density of the alveolar bone of patients with chronic generalized parodontitis and bruxism
The article is devoted to the study of optical density of patients with paradentium diseases. The aim of the study was the evaluation of indicators of optical density of bone tissue of jaws using dental computerized tomography in patients with chronic generalized parodontitis. Materials and methods: in the research following methods were used: dental computerized tomography, densitometry, index estimation of paradentium tissues. The characteristics of clinical, functional features of patients were given. The method of treatment was developed. The effectiveness of this method was evaluated. The positive dynamics of clinical symptoms is more pronounced in patients that received the offered method of treatment, than in patients that received basic therapy. This revealed in the reduction of time of the treatment on 10 days in average. The disappearance of edema, hyperemia of the gingiva, pain and bleeding during the probing and during eating, the restoration of densely elastic consistency of the gingiva, correct configuration of marginal papillae and full gingival edge are clinically revealed. Complex use of basic therapy, laserphoresis with Kanalgat gel in patients with chronic generalized parodontitis of mild severity caused to significant increase in the clinical effectiveness of treatment.Π¦Π΅Π»ΡΡ ΡΠ°Π±ΠΎΡΡ ΡΠ²ΠΈΠ»ΠΎΡΡ ΠΎΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ ΠΏΠΎΠΊΠ°Π·Π°ΡΠ΅Π»Π΅ΠΉ ΠΎΠΏΡΠΈΡΠ΅ΡΠΊΠΎΠΉ ΠΏΠ»ΠΎΡΠ½ΠΎΡΡΠΈ ΠΊΠΎΡΡΠ½ΠΎΠΉ ΡΠΊΠ°Π½ΠΈ ΡΠ΅Π»ΡΡΡΠ΅ΠΉ Ρ ΠΏΠΎΠΌΠΎΡΡΡ ΠΌΠ΅ΡΠΎΠ΄Π° Π΄Π΅Π½ΡΠ°Π»ΡΠ½ΠΎΠΉ ΠΊΠΎΠΌΠΏΡΡΡΠ΅ΡΠ½ΠΎΠΉ ΡΠΎΠΌΠΎΠ³ΡΠ°ΡΠΈΠΈ Ρ ΠΏΠ°ΡΠΈΠ΅Π½ΡΠΎΠ² Ρ Ρ

USE OF PHASE-CONTRAST MAGNETIC RESONANCE IMAGING TO QUANTIFY CEREBROSPINAL FLUID DYNAMICS IN PATIENTS WITH COMMUNICATING HYDROCEPHALUS
Objective: to determine differences in cerebrospinal fluid (CSF) flow velocities in patients with varying degrees of communicating hydrocephalus (CH) versus a group of healthy volunteers without hydrodynamic disorders. Material and methods. The investigation enrolled 27 CH patients (17 and 10 patients with an Evans index of 0.31 and 0.46, respectively) and 62 healthy volunteers. Average, volumetric, and peak flow velocities were determined at different intracranial levels. Results. Analysis of differences between the mean values indicated that the patients with CH were observed to have progressive cranial cavity CSF outflow obstruction that depended on the degree of dilation of the ventricular system and, probably, on impaired CSF reabsorption. These changes can provide an explanation for the clinical symptoms present in the patients and also serve as diagnostic criteria. Conclusion. The investigation showed that phase-contrast magnetic resonance imaging might be used to estimate the quantitative indicators of CSF in health and in varying degrees of CH. The velocity characteristics of antegrade and retrograde CSF flows are significantly different in health and in disease, which mayΒ be relevant to neurologists and neurosurgeons when planning therapy and surgery options
Electron Beam Loss Monitor of Areal Accelerator Based on Pin-Photodiodes
A prototype PIN-photodiode-based electron system for flux measurement of the AREAL accelerator electron beam (energy up to 5 MeV) was developed and tested. The system can be eventually used to measure beam losses from the vacuum chamber of the SASE100 undulator, which is intended for the generation of radiation in the terahertz range and will be installed in the AREAL accelerator tract during its modernization. The method of using the PIN-photodiodes as a beam loss monitor is based on the effect of electron-hole pairs formation when ionizing particles pass through the photodiode barrier layer. Calculations of the interaction of electrons with the substance of the barrier layer are performed using the PCLab program. The experiments carried out on the accelerator electron beam showed that the developed system can effectively register the electron fluxes of both the main beam of the AREAL accelerator and its dark current
