[Problem of predicting occupational morbidity among workers in the iron ore mines of the Krivoĭ Rog region].

The article represents the morbidity prognosis of silicosis, dust bronchitis, cochlear neuritis, vibration disease, trinitrotoluene cataract. Only the morbidity prognosis of silicosis proved to be stable, because the objective diagnosis makes its level close to true.

[Immunocorrecting properties of low-frequency ultrasound].

The possibility to correct the secondary immunodeficient state by means of two- and three-fold low frequency ultrasound effect on the spleen has been demonstrated on mice of CBA strain. It makes it possible to use low-frequency ultrasound on a large scale in the clinical practice.

[Dynamics of the infraslow omega potential and of the spatial synchronization of the EEG in muscle fatigue].

The object of the present study was the dynamics of infraslow omega-potentials and EEG interrelated activity modifications in young and adult (19-25 years old) sportsmen during strenuous endurance exercise on a cycle-ergometer. Correlation and coherence analysis revealed at the initial stage of muscle fatigue an increase of close relationship (synchronization and in phase readjustment) of different cortical areas potentials mainly between the prefrontal and precentral cortex. It is suggested that this phenomenon is an EEG reflection of voluntary increase of fatigue overcoming.

[Effect of ultrasound on cellular and humoral immunity factors].

Experiments on CBA mice were performed to explore the changes in the body immunoreactivity induced by low intensity ultrasound. A study was made of the content of lysozyme, properdine, T and B rosette-forming lymphocytes, and complement in the peripheral blood, the histophysiological properties of the lymphoid organs, and the titer of pertussis antibodies. It has been disclosed that ultrasound has a stimulant effect, primarily on the T system immunity, which was confirmed during immunization with B.

[Transformation of cortical functional systems during the process of motor habit formation and disruption].

Specific cortical functional systems with synphasic and coherent activities were revealed in the left hemisphere as reflecting the motor program by means of the topical specifics. Diminishing of the activity synchronous character in the precentral and prefrontal areas and its increasing in the precentral and parietal inferior areas occurred in the course of motor automatization, i.e.

[Classical and current aspects of the formation of motor dominance in man].

In the paper, significance of driving phenomenon for formation of motor dominant is considered and experimentally corroborated with the aid of autocorrelation and spectral analysis of the working man's EEG. The A.A.
