Non-uniform distribution patterns in different organs were registered, irrespective of the presence or absence of malignancy.

[Distribution of Cs-137 in bodies of inhabitants of the Vitebsk Region].

The content of 137Cs in the whole human body and certain internal organs has been determined using gamma-spectrometry method for inhabitants of Vitebsk Region. The average activity of 137Cs in the whole human body was obtained to be 0.038 mkCu.

[Radionuclide pollution of the Vitebsk region].

The 137Cs content has been determined for probes of flora, fauna, food, soil and autopsy material from Vitebsk Region. The 137Cs content was established not to be more, than the Republic Control Levels of 1992. The dynamic of 137Cs accumulation in potato for 1981-1995 has been shown.

[Current aspects of the noise problem in aviation medicine].

The authors discuss the problem of improvement the noise factor prevention in aviation medicine. The analysis of the real acoustic load on aviation engineer specialists, performing maintenance of the modern military aircraft have been given. The authors show the importance of the approach to the aviation noise as an ecological significant factor, that means taking into account the acoustic load during work time as well as during rest-sleep periods.

[Theoretical aspects of rehabilitation and occupational health of pilots].

Some theoretical aspects of the rehabilitation problem and its interaction with the problem of professional health of pilot have been discussed in this paper. The authors have proposed methodologic approaches to the essence of medical and professional rehabilitation; classification of the main directions and types of rehabilitation, the principles of its application in flying practice as well as the question about economic advisability have been studied. As the main lines of medical rehabilitation there suggests the nosologic, psychologic and physiologic, professional (singly) rehabilitation with consideration of the labile and base components of professional health of pilot.

[Changes in specific sensation in pilots exposed to systematic general vibration].

Helicopter pilots exposed to excessive general vibration demonstrate changes of specific sensation (vibrotactile, vestibular, auditory), that could be signs of occupational disorder. Those changes are increased thresholds of vibrotactile sensation, lower vestibulovegetative stability, changed vestibulospinal reflexes, more common occurrence of consistent deafness for voice frequencies in comparison with jet aircraft pilots. Experimental vibration (50-1,800 (m/s2) 2 hour) caused no changes of the vibrotactile and auditory sensation, and the modified vestibular function could prove the increased vestibular reactivity.

[Aviation noise as an ecological environmental factor].

Average diurnal doses of noise, received by aviation engineers servicing up-to-date aircrafts and living near air fields, were analyzed. The doses appeared to outnumber the normal values, especially during the work and the sleep. The examinees living in 1-2 km from air fields were proved to have significantly higher auditory thresholds for 1,000-8,000 Hz, in comparison with the examinees residing 5-6 km apart.

[Role of optokinetic stimulation in realizing vestibulospinal reflexes].

This paper presents data about the effect of optokinetic stimulation (OKS) on vestibulospinal reflexes and discusses mechanisms of interaction of the vestibular, optic and proprioceptive sensors during their combined stimulation. The vestibulospinal reflexes were investigated using a 2-minute step test and simultaneous OKS that was produced by a portable optokinetic drum mounted on the head of the test subject. During the tests optokinetic nystagmus was recorded and the angle of body rotation relative to the initial position was measured.

[Effect of altered blood circulation on human nystagmic reactions].

Optokinetic and vestibulo-optokinetic nystagmus in response to optokinetic and combined vestibulo-optokinetic stimulation applied during head-down tilt was investigated. Tilt-induced circulation changes produced a modifying effect on nystagmic reactions which included a decrease of optokinetic and vestibulo-optokinetic nystagmus and its subsequent recovery after return to the horizontal position. The absolute parameters of vestibulo-optokinetic nystagmus changed depending on the direction of head movements in the sagittal plane relative to the long axis of the body.

[Dissociation of vestibular autonomic and sensory reactions].

The studies of healthy people and test subjects with vestibular reception disorders yielded data about relative independence of the vestibulo-autonomic and vestibulo-sensory reactions during routine vestibulometric and tilt tests. The subjects with a changed labyrinthine function showed a higher vestibulo-autonomic stability as compared to those with normal hearing. In both groups the sensory component of vestibular reactions did not differ significantly.
