Research results of application of reflexo-therapy in correction of myopia

Objective: To develop the optimum scheme of acupuncture, aimed at improving the functional status of the visual analyzer in patients with myopia. Materials. Treatment was conducted in the main group by reflexology courses in 10 procedures and basic therapy in the control group, only basic therapy. The examination included the classic ophthal-mologic research methods, ultrasound and Doppler echoofthalmografy with color mapping of blood vessels — the ophthalmic artery (OA), central retinal artery (CRA) and posterior long ciliary arteries (ZDTSA), the study of visual efficiency and visual assessment of the subjective expression of asthenopia. The results of these studies were subjected to statistical analysis using the method of variation statistics with the computation of the arithmetic mean (M), the average error of the arithmetic mean (m) and the level of significance (p). Differences between mean values were considered significant if the probability of errors on the distribution of Student»s less than 0,05. The result showed a pronounced effect method of acupuncture on the clinical features, hemodynamic and ergonomic eye, the severity of visual fatigue and general condition of patients. Conclusion. The use of corporal-auricular acupuncture technique in patients with myopia allowed to increase the visual acuity without correction in 1,6 times, visual acuity with correction in 1,2 times, lower rates of subjective and objective refraction in an average of 29.8 and 32.4%, increase rates of accommodation of more than 1,5 times, to increase blood flow velocity characteristics in the GA by an average of 9.7, the CAC at 33.4 and ZDTSA by 27,5%. All this is possible to reduce the severity of subjective indicators of asthenopia in 58% of cases and to increase visual efficiency by 11,3

Estimation of Hydrodynamical Model Parameters from the Invariant Spectrum and the Bose-Einstein Correlations of pi-mesons Produced in (pi+/K+)p Interactions at 250 GeV/c

The invariant spectra of pi- mesons produced in (pi+/K+)p interactions at 250 GeV/c are analysed in the framework of the hydrodynamical model of three-dimensionally expanding cylindrically symmetric finite systems. A satisfactory description of experimental data is achieved. The data favour the pattern according to which the hadron matter undergoes predominantly longitudinal expansion and non-relativistic transverse expansion with mean transverse velocity = 0.20(7), and is characterized by a large temperature inhomogeneity in the transverse direction: the extracted freeze-out temperature at the center of the tube and at the transverse rms radius are 140(3) MeV and 82(7) MeV, respectively. The width of the (longitudinal) space-time rapidity distribution of the pion source is found to be Delta eta = 1.36(2). Combining this estimate with results of the Bose-Einstein correlation analysis in the same experiment, one extracts a mean freeze-out time of the source of = 1.4(1) fm/c and its transverse geometrical rms radius, R_G (rms)=1.2(2) fm.Comment: latex, 14 pages, 5 figure

Boost Invariance and Multiplicity Dependence of the Charge Balance Functionin π+p\pi^{+}p and K+pK^{+}p Collisions at s=22\sqrt s= 22 GeV/c

Boost invariance and multiplicity dependence of the charge balance function are studied in \pi^{+}\rp and \rK^{+}\rp collisions at 250 GeV/$c$ incident beam momentum. Charge balance, as well as charge fluctuations, are found to be boost invariant over the whole rapidity region, but both depend on the size of the rapidity window. It is also found that the balance function becomes narrower with increasing multiplicity, consistent with the narrowing of the balance function when centrality and/or system size increase, as observed in current relativistic heavy ion experiments.Comment: 4 pages, 5 figures, Revte

Entropy Analysis in \pi^{+}\rp and \rK^{+}\rp Collisions at s=22\sqrt{s}=22 GeV

The entropy properties are analyzed by Ma's coincidence method in \pi^{+}\rp and \rK^{+}\rp collisions of the NA22 experiment at 250 GeV/$c$ incident momentum. By using the R\'{e}nyi entropies, we test the scaling law and additivity properties in rapidity space. The behavior of the R\'{e}nyi entropies as a function of the average number of particles is investigated. The results are compared with those from the {\sc Pythia} Monte Carlo event generator.Comment: LaTeX, 11 pages, 5 figure to be appeared in Acta Phys. Pol.

Self-affine scaling from non-integer phase-space partition in π+p\pi^{+}p and K+pK^{+}p collisions at 250 GeV/cc

A factorial-moment analysis with real (integer and non-integer) phase space partition is applied to $\pi^+$p and K$^+$p collisions at 250 GeV/$c$. Clear evidence is shown for self-affine rather than self-similar power-law scaling in multiparticle production. The three-dimensional self-affine second-order scaling exponent is determined to be 0.061$\pm$0.010.A factorial-moment analysis with real (integer and non-integer) phase space partition is applied to $\pi^+$p and K$^+$p collisions at 250 GeV/$c$.

Large Self-affine fractality in \p^+p and K+^+p collisions at 250 GeV/cc

Taking into account the anisotropy of phase space in multiparticle production, a self-affine analysis of factorial moments was carried out on the NA22 data for \p^+\Pp and \PK^+\Pp collisions at 250 GeV/$c$. Within the transverse plane, the Hurst exponents measuring the anisotropy are consistent with unit value (i.e. no anisotropy). They are, however, only half that value when the longitudinal direction is compared to the transverse ones. Fractality, indeed, turns out to be self-affine rather than self-similar in multiparticle production. In three-dimensional phase space, power-law scaling is observed to be better realized in self-affine than in self-similar analysis.Comment: 10 pages and 4 figure

Dynamic regulation of cerebral blood flow and it's clinical, and laboratory markers in elderly patients with arterial hypertension

Aim: to estimate the dynamic regulation of cerebral blood flow (CBF) and significance of clinical, and laboratory parameters as a possible markers of CBF violations. Material. 179 elderly patients with arterial hypertension were involved in the study. Transcranial Doppler ultrasonography (Philips Envisor HD, USA) was used for CBF parameters dynamics during orthostatic hypotension. Results. Main directions of CBF parameters changings (Friedman ANOVA p 0,0091 ... 0,012, coeff. of concordance 0,308 ... 0,691) were detected. Gender differences of CBF parameters, as well as blood pressure level influence upon CBF regulation during orthostatic hypertension were studied. Conclusion. Received data allow us to consider gender, controlled or uncontrolled hypertension, cytomorphological parameters of peripheral blood, diuretics usage as clinical, and laboratory markers of dynamic regulation of CBF in elderly patients with arterial hypertensio

Age dependent dynamics of intima-media complex thickness in elderly patients with arterial hypertension

Aim: To estimate the dynamics of intima-media complex in elderly patients with arterial hypertension. Materials: 179 elderly patients with arterial hypertension were involved in the study. Mean intima-media wall thickness (IMT) of common carotid arteries in plaque-free sites and prevalence of plaques were evaluated by B-mode ultrasound investigation (Philips Envisor HD, USA). Results: IMT changing was of nonlinear character, remained stable up to 74 years. Mean rate of the following IMT augmentation was 0.157 mm per year. Frequency of atherosclerotic plaque revealing was significantly increased since the 7th decade. Significant correlation between IMT and systolic, diastolic, mean blood pressure levels or medication spectrum was not revealed. Conclusion: Received data proved significant influence of aging upon IMT enlargemen
