Mechanism of selective lesion of the cardiovascular system in psycho-emotional stress

A species predisposition to hypertensive and ischemic heart disease occurs in mammals only at the level of primates, and is associated with social regulation of biological reactions. The specific physiological mechanism giving rise to psychonerogenic pathology may be an inhibition of the motor component of the agressive-defensive response. Repeated combination of pursuit with subsequent immobilization resulted in four out of five experimental baboons developing serious arterial hypertension and ischemic lesion of the heart which lasted many years

Hormone supply of the organism in prolonged emotional stress

The effect of prolonged emotional stress of varying genesis on the hormonal function of the pancreas, thyroid gland, and adrenal cortex was studied. The amount of the hormonal secretion was found to depend on the type of adaptation activity and its duration. High secretion of the hormones observed outside the adaptation activity was examined as an index of the phase transition of defense reactions to the phase of overstress

Morphological and functional manifestations of rat adrenal-cortex response to sodium bromide administration under hypodynamic stress

Functional and morphological manifestations of adrenal cortex response to hypodynamia (2-hr immobilization on an operating table) under the influence of bromine preparations were studied. The sodium bromide was administered intraperitoneally in 100, 250, and 500 mg/kg doses once and repeatedly during ten days. The adrenal gland was evaluated functionally by ascorbic acid and cholesterol content and morphologically by coloring it with hematoxylin-eosin and Sudans for lipid revealing at freezing. Results are displayed in two tables and microphotographs. They are summarized as follows: the bromine weakens the functional state of the adrenal cortex in intact rats, causing changes similar to those under stress. During immobilization combined with preliminary bromine administration, a less pronounced stress reaction is noticeable

Occupational hypokinesia as a hygienic problem

Insufficient motor activity at the work place is discussed as a widely prevalent problem reducing worker efficiency and adversely affecting worker health. Some guidelines are provided for evaluating and promulgating measures to prevent and correct hypokinesia at the work place and compensate for it during off-hours. Suggestions included developing standards for optimal work-related motor activity and setting limits for its reduction

Emergent processes as generation of discontinuities

In this article we analyse the problem of emergence in its diachronic dimension. In other words, we intend to deal with the generation of novelties in natural processes. Our approach aims at integrating some insights coming from Whitehead’s Philosophy of the Process with the epistemological framework developed by the “autopoietic” tradition. Our thesis is that the emergence of new entities and rules of interaction (new “fields of relatedness”) requires the development of discontinuous models of change. From this standpoint natural evolution can be conceived as a succession of emergences — each one realizing a novel “extended” present, described by distinct models — rather than as a single and continuous dynamics. This theoretical and epistemological framework is particularly suitable to the investigation of the origin of life, an emblematic example of this kind of processes

Defining and diagnosing the gifted students

The article contains the research of the phenomenon of giftedness and the ways of its diagnosis. The interdisciplinary analysis enables to derive at the conclusion about genetic connection of talent with the creative and intellectual aspects of a personality. The study is based on methodological aspects when the research proceeds from the universal to the particular, and from the latter – to the singular. On the level of philosophical methodology the universal paradigm of development is applied enabling to ground, that creativity, giftedness and intellect have certain genetic ties being realized in the process of a person's development: the man develops from the state of giftedness, characterized by the functions of right hemisphere of the cerebrum realizing multiple, emotional and image reflection of reality, high affective and perceptive sensitivity being the indicators the very giftedness – that right hemispheric developing potential of man which must be sublimated into left hemispheric intellectual (analytical, abstract and logical) forms of psychical activity. On the third stage of man's development the unification of right- and left hemispheric functions reveal the psycho physiological basis for creative (paradoxical, dialectical) thinking and mastering of reality. The mentioned stages determine pertaining proper strategies of the diagnostics of giftedness

APPLYING OF ACTIVITIES MANAGEMENT BASED ON SELF-LEARNING

The article is devoted to a brief presentation and application in practice of an effective management way of human activities and human-technical communities one. This way was called Method of statistical regularity (Method of self-organizing processes). In fact, this is a system approach. For the first time, the application of this approach is shown on the example of quality management of the technological process. Practical management is shown using an algorithm. The effectiveness of the author's system approach is explained by the consideration of the final result of the activity as a goal and a system-forming factor of activity, taking into account the individual features of the management object, real statistics of activity. The system approach described in the article is a universal devise of management. It can be used and already used to manage individual functions of the enterprise, the process, the human operator, the communit

About the personal approach in physical education of students

In recent scientific publications on improving the students’ physical education learning process, many authors point to the need for a personal approach to each student, but the technology of such an approach are not described. The research conducted at the Department of Physical Education and Health of Ryazan State Medical University has shown that the methodological basis of the personality-oriented educational process of physical education of students is a systematic approach. The approach offered by P. K. Anokhin, aims to get the final useful result in the process of any activity. The low level of motivation for regular physical exercises noted among students largely depends on the fact that students do not know what useful result they will receive from classes and when they will get it. Tested at the Department of Physical Education and Health of Ryazan State Medical University for many years, the methodology of individual planning to increase the level of physical fitness when passing the physical fitness standards is easy to apply, but the use of tables in each university should be different according to the local contingent of students
