Abstract
To study variability of enzymatic apparatus of opportunistic enterobacteria.
Clinical strains of Morganella morganii, Citrobacter freundii, Proteus mirabilis isolated from patients treated in Irkutsk Regional Hospital for Infectious Diseases. Activity of cellulase and lipase as well as amount of auxins and gibberellins was studied in these bacteria at different cultivation temperatures.
It was shown that studied species isolated from humans enterobacteria are able to produce plant growth regulators amount of which depends from cultivation temperature and type of microorganism. Activity of cellulase sharply rises if temperature falls.
Obtained results show high adaptation potential of opportunistic bacteria from Enterobacteriaceae family. Switch on saprophytic mechanism after fall of temperature to environment-corresponding values allows them to survive in soil and arrange different interactions with soil biota including plants.

Sex Characteristics
Abstract
Results are submitted of the study into the role of sex features of reactivity and adaptivity in the organization and compensation of structural and functional changes in the central nervous system in newborn babies having suffered intrauterine hypoxia and born in asphyxia. The identified sex dimorphism of the neuroendocrine system attests to the need for taking account of sex resistance in neonatology and permits the awareness of better adaptation of newborn girls with cerebral disorders of hypoxic genesis. Further study of sex dimorphism will, we believe, help in working out informative-and-quest systems of clinical, instrumental, biochemical, and morphological diagnosis in neonatology.

Abstract
The purpose of this study was analysis of forensic medical aspects of macro- and trace element composition of hairs of the head in the residents of Mexico, Ecuador, Bolivia, Brazil, Columbia and changes in this characteristic during adaptation to conditions of Central Russia. One of our tasks was to define expert criteria for differentiation between the hairs belonging to residents of these countries and Russia. A total of 136 hairs were examined by spectral approximated quantitative analysis using DFS-13 spectrographer. The detected regularity consisted in the following: adaptation of residents of Latin America to conditions of Central Russia was associated with disappearance of some elements and appearance of other ones characteristic of residents of Central Russia (Byelorussians, Russians, Ukrainians).

Abstract
The preservation of human health in polar and circumpolar regions depends mainly on the strategy for future development of these regions. The consequences of human intervention into northern ecology are irreversible, as in the case of greenhouse effect, industrial and atomic pollutions of polar nature, tundra devastation, destruction of northern flora and fauna, etc. The ongoing creation of large-scale industrial population centers in the North due to newcomers is to be stopped. Polar regions are to be used for biospheric reservation and tourist sanitary zones, to preserve specific flora and fauna, to provide the rhythms and customs necessary to survive in extreme climatic and geophysical conditions of high latitudes. The programme for securing man's survival in circumpolar regions should comprise several stages of practical measures to provide necessary resources and to combine international efforts. The preservation of human health should be based on the understanding of the relationship between the health status and biospheric processes and the assessment of the role of human intervention into polar ecology. A programme facilitating the preservation of human health and survival in the North and in the Antarctic should be launched.

Abstract
Differences in the degree of separate and combined effects of temperature, pH, and heavy metals (zinc, copper) on the trypsin- and chymotrypsin-like proteinase activities have been established in the whole body of some invertebrate animals - potential objects of fish nutrition: pond snail Lymnaeae stagnalis, orb snail Planorbis purpura, zebra mussel Dreissena polymorpha, oligochaetae Tubifex sp. and Lumbriculus sp. in total, chironomid larvae Chironimus sp. and Ch. riparus, as well as crustacean zooplankton. It has been shown that enzymes of the potential victim at a low temperature can compensate low activity of intestinal proteinases of fish bentho- and planktophages.

Abstract
Disorders of dietary sugar assimilation occur more often among native people of the Arctic then in temperate climate inhabitants.It is hypothesized that the limited variety of natural exogenous sugars in the Arctic, and their low content in the traditional diets of native northerners in accordance with a "protein-lipid" type of metabolism weakened selection, favoring diversity of disaccharidase enzymes.
