[Fractal characteristics of the functional state of the brain in patients with anxious phobic disorders].

The task of estimation of the functional state of the human brain during psychotherapeutic treatment of psychogenic pain in patients with anxious phobic disorders is examined. For solving the task the methods of spectral and multifractal analyses of EEG fragments are applied during the perception of psychogenic pain and its removal by the psychorelaxation technique. Contrary to power spectra singularity spectra allow to distinguish EEGs quanitatively in the examined functional states of the human brain.

[The energy and fractal characteristics of the physiological and pathological tremors of man's hand].

The tasks was to execute the comparative analysis of involuntary fluctuations (tremor) that are appeared during sustaining of isometric effort by the hands at healthy man and exist at patients with the tremulous form of parkinsonism. For the decision of this task we have applied the fractal analysis and multilevel wavelet-decomposition of tremors with subsequent valuation of the energy characteristics determined on the basis of spectral density of energy of detailed components that can be received at different levels of decomposition. Have found that the computed fractal and energy quantities of tremor at healthy examinees were significantly less than the same characteristics at the patients.

Method for studying the processes maintaining equilibrium at rest standing.

According to current concepts, two processes are responsible for the maintenance of body equilibrium: shifts of the reference point caused by changes in the posture and stabilization of oscillations of the center of mass relative to this point. Exact changes in these processes occurring at various forms of locomotor disorders remain unclear. We proposed an original mathematical method allowing separate evaluation of these two processes responsible for the maintenance of body equilibrium.

[Postmanipulation hemostasis in angiography from different approaches].

The paper is concerned with some data on the quality of hemostasis after various types of angiography in 629 patients: manual hemostasis in transfemoral catheterization was used in 130 patients, mechanical fixing rubber pellets were used in 108 patients. Postmanipulation tamponade in the area of catheterization was used in 163 of 321 patients after catheterization translumbar angiography. In mechanical hemostasis, hematomas were found in 1.
