Metabolic correlates of behavior in animals upon single influence of extremely low frequency magnetic field
The influence of the magnetic field of 8 Hz 5 microtesla on the relationship of animal behavior in the “open field” with the activity of metabolic processes in different brain structures was studied. It was shown that metabolic links
are important in behavior of animals in the new environment. The most important connection of metabolic parameters with the activity of animals in the “open field” occur in the cerebral cortex and hypothalamus. The response of animal organism to the effect of alternating magnetic field depends on the individual-typological characteristics. In animals with middle and high level of activity in the “open field”, in response to MF 8 Hz the cerebral cortex played more active role, whereas in animals with low activity - the thalamus and the hypothalamus.
The general nature of disorders of the relationships of behavior indices and metabolic processes is characterized by leveling the initial differences between different individual-typology groups. In the stereotypical response of CNS to the action of alternating magnetic field the hemispheric asymmetry plays an important role, with the dominant role of right hemisphere.

Research of dynamics РАСО2 during intensive muscular activity
The research was carried out on the exterior breathing functions of high and low qualified sportsmen during their work on the cycle-ergometer up to gull fatigue. It was revealed that in intensive physical exercise the human aerobic capability depends on the elimination of CO2 and lowing of the general quantity of carbon dioxide level in the body, that is understood from the carbon dioxide level in the alveolar air and arterial blood getting low. The verified prognostic parameter of the functional condition of the exterior breathing and human aerobic capability is PACO2. The higher is PACO2 under standard work, or the later it decreases under maximum work, the higher is the level of work capacity and aerobic capability of the human body.

Acoustic activity of a dolphin female and its calf (Tursiops truncatus ponticus Barabasch) in early ontogenesis in оceanarium conditions
We have studied acoustic activity of a Tursiops truncatus female and a calf born in оceanarium (6 weeks aged) during their simultaneous and single swimming, rest, orientative-exploratory behavior, as well as feeding the female by a trainer. Dolphin signals were digitally audio-taped during video filming behavior elements. In the result of our researches we’ve sorted out 16 types of acoustic signals, 8 of which had their sub-types. The change of occurrence frequency in different types due to different conditions is revealed. The results prove diversity of acoustic signals during female-calf interaction as well as relation of acoustic activity with the interaction form displayed.
The peculiarities of rats’ behaviour with different type of motor assymetry under the circumstances of combinative influence of chronic hypokinetic and pain stresses
The influence of hypokinetic (HK) stress on the change of rats pain sensitiveness at the sharp tonic pain is studied. It is shown that the chronic stress on the mobility limitation influence modificatively on the level of rats’ pain sensitiveness at the sharp tonic pain, nevetheless this effect depends on the durability of the mobility limitation (at the early terms HK stress pain sensitiveness diminishing was observed, and at the later terms, vice versa - increase), and on animals’ individual-typological peculiarities (“left-handed” rats are the most sensitive to the pain stress, and “right-handed” rats and “ambidexters” are the less sensitive).
The respiratory rhythm, as one of the Biorhythmological performance criteria of adaptive control mechanics of respiration athletes in different phases of the menstrual cycle
In this paper we study how to regulate the mechanics of breathing in athletes in different phases of the menstrual cycle. We discuss the influence of hormonal athletes on the sensitivity of the respiratory center to carbon dioxide. Much attention is paid to the respiratory rhythm, and methods of mathematical analysis. In particular, it is recommended to use the periodogram analysis of the respiratory rhythm, because this analysis allows the most adequate to estimate the frequency of respiratory movements throughout the test. And thus determine the influence of the frequency component at the value and mechanical ventilation parameters of respiration, as well as to predict the effectiveness of respiratory reactions of athletes to physical loads in a certain period of training and competitions.
The effect of vasopressin on oxygen balance, heat generation and bile formation in liver
In acute experiments on nembutal anesthetized dogs and chronic experiments on dogs, studied the effect of vasopressin on the oxygen balance, heat generation and bile formation in liver. The study showed that, injection of vasopressin at the vasoactive dose in portal vein increased heat generation and O2 consumption, parallel to a short time decrease in O2 delivery, while the pO2 in liver is decreased. In non vasoconstrictive dose, vasopressin increases volume speed of choleresis, intensity of deoxycholic acids biosynthesis in hepatocytes and conjugation of bile acids
