[Biofeedback of human heart rate: adaptive module].

Ecological issues, that are not in line with the adaptive opportunities of man, prompt the designing of computer-based systems for psychophysiological support of traditional methods of prevention, diagnostics and rehabilitation. An adaptive module of biofeedback was developed for monitoring the human heart rate. The system can be applied in a variety of medical spheres, like evaluation of adaptive potentialities of different body systems, enhancing of the body's reserve and of its efficiency; mobilization of latent or lost abilities to adapt; training of skills of relaxation, self-regulation and self-control; correction of the condition of persons at different stages of occupational, ecological psychological and social stress; and preliminary psychophysiological preparation for responsible operator tasks.

[The mechanisms of central regulation disorder under combat exposure conditions]. / Mekhanizmy narusheniia tsentral'noi reguliatsii v usloviiakh boevykh deistvii.

Results of research in central regulation system's disorders in the local wars' participants suffering from environmental psychoemotional and traumatic stress. It has been established, that there was an upsetting of interaction between neurodynamic processes in the sub-dominant hemisphere and a reduction of the functional reserve of the brain. Neurophysiology disorders discovered come from the pathological system that had been formed up in the central nervous system preserve their persistence for several years after the war.

[The biological action of physical factors in the critical periods of embryogenesis]. / Biologicheskoe deistvie fizicheskikh faktorov v kriticheskie periody émbriogeneza.

The critical period in a chicken embryonic development (the 10-13-th days of incubation) is revealed under total electromagnetic radiation. This external factor is a physiologically active irritant which can influence functional state of the brain. The increased absorption of electromagnetic energy takes place in this incubation period. Its dynamics within 20 days of embryonic development has phasic, up and down character. Electromagnetic exposure (4 hours a day daily) in the above mentioned period evokes a delay in embryo adaptive motor behavior (biofeedback learning). Morphological investigation shows significant pathological changes--destruction of share brain synapses. The delay in embryo hatching for a day is also detected. Radiation exposure within other periods of incubation (3-6-th or 12-15-th days) was not effective with respect to formation of normal motor pattern in biofeedback experiment.

[The adaptation of the human central nervous system to ecological job factors]. / Adaptatsiia tsentral'noi nervnoi sistemy cheloveka k ékologo-professional'nym faktoram.

The EEG, quantity of cation proteins in neutrophils, the opioid peptides concentration in the CSF, were analysed in military personnel after a prolonged climatic and specific stress complicated by traumas, at the Kabul military hospital in Afghanistan. The brain functional reserve was significantly lower in the control subjects. A positive correlation between the brain functional reserve and the average cytochemical coefficient, was found in certain phases of traumatic disease alone. Accumulation of opioid peptides occurred under the adaptation to stress, being more evident in wounded soldiers.

[The effect of microwaves on the neuronal activity of the hyperstriatum in chick embryos at the critical developmental period]. / Vliianie mikrovoln na neironnuiu aktivnost' giperstriatuma kurinykh émbrionov v kriticheskii period razvitiia.

Studies have been made on multineuronal activity in the dorsal hyperstriatum of chick embryos exposed to microwave radiation (2.375 MHz) at critical stage of development of the structure (19th day of incubation). One day after microwave exposition, activation of neurones was observed in a form of the increase in the discharge frequency and the increase of outburst form of the activity. Cyclic form of outburst activity was absent in experimental animals being present in control embryos of the same age and associated presumably with self-organization of microsystems of neurones in the developing brain. Changes in multineuronal activity were found only in the left hyperstriatum, which is probably due to different levels of the development and functional activity of the right and left hyperstriatum at this stage resulting from asymmetric intensity of visual afferentation which depends on the position of embryo inside the egg.

[The effect of microwave irradiation on the peroxide modification of low density lipoproteins in human blood serum]. / Vliianie mikrovolnovogo oblucheniia na perekisnuiu modifikatsiiu lipoproteidov nizkoi plotnosti syvorotki krovi cheloveka.

In experiments in vitro the electromagnetic field of 2375 mHz, 500 microW/cm2 was shown to influence peroxide modification of low density lipoproteids. It was also shown that this modifying effect was prevented by high density lipoproteids that decreased the level of lipid peroxidation.

[Systematic analysis of the state of man exposed to radio wave irradiation for a long time]. / Sistemnyi analiz sostoianiia cheloveka pri dlitel'nom radiovolnovom obluchenii.

A complex examination was made of 72 men--short-wave (3-30 MHz) radio equipment controllers. Two parallel control groups of 70 people all in all were examined. No regular changes in the dynamics of amplitude-frequency characteristics of electroencephalogram, associated with the length of service, were observed. The number of subjective complaints from people in contact with radiofrequencies increased with an increase in the length of service. The role of certain clinico-physiological parameters of the organism in the process of adaptation to electromagnetic radiation was quantitatively assessed with the use of status-metry technique; in particular, a decrease in the functional activity of the right hemisphere brain structures, aggravating with the length of service, was observed.

[Experimental analysis of biological effects of microwaves: their systemic, ultrastructural and neuronal mechanisms]. / Eksperimenta'lnyi analiz bioéffektov mikrovoli: sistemnye, u'ltrastrukturnye i neironnye mekhanizmy.

For 200 hours the cats were exposed to microwaves of 2375 mHz, the energy current density being 500 mWt/cm2. 6 diversions of the electrocorticogram and multi-cellular activity were registered by coal electrodes. After the exposure an electro-microscopic study of the lateral hypothalamic brain field was carried out. Under the radiation effect synchronization of slow bioelectric activity over the range of 6-10 to 12-16 took place. The analysis of the conditional probability matrix of series generation of action potential in the studied structures demonstrated their functional separation according to multi-cellular activity parameters in proportion to exposure growth. Damage of axodendritic synapses which provided morphologic links between brain structures was considered its morphologic substrate.

Albino rats were exposed to 2375 mHz microwaves of 500 microW/cm2 for 169 h. At the time of exposure, the body mass growth diminished, the efficiency and vertical motor activity decreased in exposed animals in comparison with the controls. Three types of radiation-induced damages were found in the brain: chromatolysis, pyknosis, and ischemia. Different brain parts displayed different sensitivity depending on their location in relation to transverse sutures of the skull.

[Cyclic interactions in the processes of adaptation regulation]. / Tsiklicheskie vzaimodeistviia v protsessakh adaptivnogo reguli- rovaniia.

Human adaptation is characterised by essential changes of functional systems biorhythms which appears in the changes of their components' sequence and in the dynamics of biorhythmological cycles. These objective laws, having been described for human EEG, allow to discern clearly the individual-typological peculiarities in man with different stages of adaptation, the same as the adaptive shifts during long-term influence of external factors. The cyclic course of adaptative processes is regarded as a measure of adaptability. With the help of biorhythmic multitude the memory is constantly satiated from the brain by discrete portions of adaptogenic information, which prevents the natural processes of the memory disintegration.

[Neuroeffects of prolonged exposure to microwaves: systemic, neuronal and electron microscope study]. / Neiroéffekty dlitel'nogo deistviia mikrovoln: sistemnoe, neironal'i élektronno-mikroskopicheskoe issledovaniia.

Cats were kept in the electromagnetic field (2375 mHz, 500 microW/cm2) for 200 h. A functional disorder was noted in the neuronal activity of the studied brain formations associated with a physical injury to axo-dendritic synapses involved in the promotion of the morphological relationship between the brain departments.

[Systemic effects of the interaction of an organism and microwaves]. / Sistemnye éffekty vzaimodeistviia organizma s mikrovolnami.

A study was made of the dynamics of neurophysiological processes, the autonomic nervous system reactions, and the behaviour of cats during long-term electromagnetic field (EMF) exposure (500 mu W/cm2, 2375 MHz). Revealed were the synchronization of the brain bioelectrical activity at 6-10 Hz and 12-16 Hz, different EMF sensitivity of the brain structures, the heart rate decrease, and the increase in the mobility and aggression of the animals. A complex of interrelated changes occurring virtually in all functional systems of the organism should be considered as a specific EMF effect.
