Features of the neuro-psychological development of orphans from 1 month to 3 years of age
The level of neuro-psychological development of orphans from 1 month to 3 years of age was assessed with G.V. Pantyukhina, C.L. Pechora, E.L. Frucht test using. Children raised in institution have delay of neuropsychological development. Such delay is related with reduction of cognitive, speech, motor, sensory and emotional development. Probably delay of neuro-psychological development is associated with changes in the processes of growth and maturation of the cerebral cortex. These changes are accompanied by later cortical nerve cells differentiation and maturation of different types of neurons, reduced the rate of dendrites and axons growth, myelination deficit and the decrease in the rate of formation of synaptic contacts with other cells in all areas of the brain.

Anticipatory changes of the human low extremity H-reflexes by the voluntary contralateral movements in man
H-reflexes of the soleus and peroneus longus muscles were studied in healthy humans lying at the prone position. Facilitation of the H-reflexes takes place at about 90 ms before the onset of the voluntary contralateral ankle joint movements. The changes of H-reflexes appears later before the contralateral movements than before ipsilateral ones. Anticipatory facilitation of the soleus H-reflex does not differ significantly at the plantariflexion and dorsiflexion of the contralateral extremity. The peroneus longus Hreflex is also facilitated in the same way before the contralateral ankle joint movement. The present results suggest that anticipatory H-reflex facilitation which rise up before the contralateral extremity movements is generalised reaction which spreads on the muscles with the different functions.

The manifestations of pyracetam adaptogenic action in the changes of background electrical activity of rats' neocortex during prolonged stress
The changes of rats' electocorticogramm (ECoG) indexes under the influence of prolonged stress and application on its background of nootropic drug with adaptogenic GABA-like action – ðyracetam were analyzed. Revealed, that the three phases were separated in the dynamics of absolute and normalized powers of ECoG waves under the isolated stress influence, which could correspond to different stages of organisms stress-response. In applying of ðóracetam the dynamics of ECoG indexes became a two-phase, that together with character of ECoG indexes changes could be a sign of drug adaptogenic action on the brain processes. The obtained data suggest that under the isolated stress influence the manifestations of sustain adaptation did not appear in background electrical activity of neocortex, that could be connected with deficit of energy caused the prolonged stress and GABAergic mechanisms.
Research of the heart-vascular system reaction during sailing on the windsurf
It is revealed that prolonged sailing in extreme weather conditions demands well-trained heart-vascular system, as temperature factor starts “distracting” heart activity from its adequate oxygen supply of the working mussels because of intensification of the skin blood flow. Thus, while windsurfing it is obligatory to take into account temperature factor, eliminating its strenuous effect on the body to the maximum. It is also shown that one of the integral figures, presenting effective heart work while windsurfing can be vegetative index Kerdo (VIK) – its positive values justify effective contracting ìyocardium function.

Blood plasma free oligosaccharides of practically healthy volunteers
The mechanisms of cellular quality control of newly synthesized glycoconjugates and the degradation of membrane and secreted ones lead to the appearance of free oligosaccharides - unbound analogues of glycans of glycoproteins, glycolipids, proteoglycans and glycosylphosphatidylinositol anchors. HPLC spectra of plasma free oligosaccharides of practically healthy donors are obtained for the first time. It is shown that the concentration of these oligosaccharides in plasma can vary but HPLC spectra of the glycans in the samples have very similar profiles. The stability of the spectra in norm can be a reliable basis for studying the changes of plasma free oligosaccharides in various diseases. The use of biomaterial of practically healthy donors as a control requires further ranking within the group and its extensions.

Adenosinetriphosphate- and calciumdependenñe mechanisms of salicylate neurotropic Effects
The adenosinetriphosphate- and calciumdependence mechanisms of adjusting of snail`s neuron activity of Helix albescens Rossm are researched. It was shown that the neutropic effects of salicylates depends on the presence of adenosinetriphosphate in a extracellular environment. At joint application of adenosinetriphosphate with salicylic and acetylsalicylic acids the oppressing effect of these acids on electric activity of snail`s neurons is removed. Adding to the extracellular environment of adenosinetriphosphate strengthens the activating neurotropic effects of salts salicylic and acetylsalicylic acids. The blockade of transmembrane current of Ñà2+ showed, that these ions did not participate in the neurotropic effects of salicylates, except for influences of calcium-dependent potassium current on the effects of salicylic acid and cobalt salicylate.
