Abstract-Present paper outlines certain possibilities for a new approach to the generalized modeling of the dynamics of living organism reaction to the changes in its environment. It is shown that there exists common functional "alignment" of the immune and psychic responses in the living organism reaction to the changes in the environment. This is manifested in the experimentally recorded matching of the response scenarios and activities in the immune and psychic domains. Thus, one may conclude that there exist two functionally matched systems (psychic and immune) tracking the external influences and responding to them. On the other hand it is feasible that one is actually dealing with a complex inseparable psycho-immune system and experimentally monitors different aspects of its activity describing these from two different points of view. Given analysis of available experimental data seems to support both of the above alternatives without giving undoubted preferences to any of them. However treating the situation form the formal logic point of view certain preferences can be given to the concept of an inseparable psycho-immune system modeled in two different ways. This approach can also resolve certain collisions happening with the attempts to describe direct interrelations between psychic and immune domains, and can lead the way to higher-level functionality models of the dynamic responses of the living organisms.

Present article discusses the physiological mechanisms of the state employees adaptation during active training in temporary groups. It is suggested that adaptive mechanisms to adverse effects may be studied basing on the concept of functional isomorphism of the psychic and immune systems. Adaptive mechanisms were studied through the monitoring of the stress factors' impact upon the law enforcement officers when training outside the places of permanent deployment. The specific purpose of present study was to evaluate the physiological indicators of the psychic, immune and endocrine systems dynamics at different stages of adaptation of the live organism to a stressful situation, hoping to get better insight into possible relations between psychic and immune domains. Through monitoring of the dynamics of the endocrine and immune responses to the psychic stimuli, it was possible to correlate the stages of the stress onset to the phases of specific immune reactions. Strong correlations between the parameters characterizing activation of the psychic and immune responses support the hypothesis of the presence of "strong cooperation" between psychic and immune domains. It supports earlier hypothesis that we are monitoring different manifestations of the functioning of a complex inseparable psycho-immune meta-system.

The research was carried out into the changes within psychic and immune domains of the Russian Nenets people migrating from the traditional northern habitat (tundra) to urban environment. It is noted that in the process of significantly changing lifestyle supposedly single ethnic group can be clearly sub-divided according to the differences in adaptation dynamics. This division reflects sociological differences and is connected to the psychoimmunological aspects. Thus, with the adaptation of forest Nenets to the new conditions of existence (from the tundra to the urban centers), we found a division of a whole ethnic group into two groups according to a social attribute, which is fixed at the psychophysiological level. First, psychic and immune domains are not only sharing a number of common features but also can have deep evolutionary connections and can be governed by similar laws. Second, the psyche and the immune system show the most important functions and properties that ensure an effective existence, generalizing the values of adaptation, protection and vitality into a single structure. Such a concept is closed to "wholeness" and "integrity"
