[Physiophilosophical fundamentals and genesis of Tsigun, Indian, and Tibetan Yoga. Paramount empirical efficacy].

This article is devoted to the analysis of physiophilosophical fundamentals and genesis of Tsigun, Indian, and Tibetan Yoga based on the overview of the relevant literature with special reference to the methodology of these physical and mental disciplines and their therapeutic and health-giving efficacy. Based on the combination of physiophilosophical categories and medical knowledge in the framework of the concept of the five primary elements, the authors illustrate the development of the systemic approach by which ancient physicians related man to nature in order to derive the adaptation principle realized through human activities. Traditional and modern aspects of these activities are considered. In the traditional context, the performance of exercises as assigned by Tsigun, Indian, and Tibetan Yoga is considered as the purposeful realization of the energy of conscience for health improvement and development and in the modern context as the realization of a novel form of psychic creative capacity to the same effect based on fruitful brainwork.

[On the methodological approach to the elucidation of mechanisms underlying therapeutic effectiveness of Cigun, Indian and Tibetan Yoga therapy].

The methodological approach is proposed allowing to objectively characterize neurophysiological mechanisms underlying therapeutic effectiveness of Cigun, Indian and Tibetan Yoga therapy. Execution of exercises stipulated in these programs is interpreted as a consciousness-inspired specific form of human behaviour (activity). Step-by-step analysis of mentally-organized body's functional systems as a neurophysiological basis of realizable behaviour is presented. Operational interpretation of internal mechanisms underlying the system's functioning permits to evaluate the stereotype brain condition actualized by specific requirements and motivations that initiates sensory deprivation to ensure priority realization of internal genetically determined activity of the human body. Mobilization of this internal activity is described as a process of selective formation of many complicated interactions between various structures of the reticular formation, limbic system, subcortical centres, and neocortex maintaining priority functioning of homeostatic mechanisms of self-regulation and inborn human behaviour. These mechanisms are believed to underlie the autoreconstructive potential of human organism by ensuring systemic correction and restoration of its functional resources.

[The prognostic significance of the histological characteristics of cerebellar astrocytomas in children]. / Prognosticheskoe znachenie gistologicheskikh osobennostei astrotsitom mozzhechka u detei.

The late term results of surgical treatment of cerebellar astrocytomas in children are compared with the specific features of the histological structure of the tumor and the volume of the surgical intervention. The authors distinguish the prognostically unfavourable characteristics of the histological structure of cerebellar astrocytomas (mitotic figures, even occasional, polymorphism of cells or nuclei, combination of dense cellularity with proliferation of endothelium in the vessels) which determine the prognosis in total or subtotal removal of the tumor. The index "volume of operation" acquires highest prognostic significance in subtotal removal of the tumor. A recurrent tumor develops in all cases after subtotal removal, irrespective of the histological structure.
