Clinical and immunological peculiarities of whooping cough at children of early age in modern stage The article show clinical and immunological peculiarities of whooping cough at children of early age. Clinical manifestation of modern whooping cough characterized by light symptoms of intoxication, paroxysmal cough, more often at night and finished discharge of viscous sputum or vomiting, sometimes with reprizes; at percussion — box sound, at auscultation — rigid breathing with dry rales. In peripheral blood — leukocytosis, lymphocytosis, accelerated ESR. Increased level of cytokines, decreased level of subpopulations of CD3+ and CD4+ lymphocytes against a background of physiological level of CD8+ and CD19+, decreased level of factors of local immunity.

Peat ecosystems in the strategy of sustainable development of the biosphere In the light of v. I. Vernadsky year, in the paper the ecological condition of the biosphere, emission dioxide of carbon and methane is estimated by Siberia bogs is considered. On the basis of a database of greenhouse gases emissions is carried out scheme of zoning of the territory of Western Siberia on emission greenhouse gas.

Development of the software product for realization of Lake Onega ecosystem model Mathematical modeling plays large role when studying water ecosystems. The software product is developed and the new algorithm of realization ecosystem model is offered. The developed software product allows to receive results of calculations for Lake Onega ecosystem.

Study of the urban soils’ ecotoxicity using biotesting methods The toxicity of urban soils’ upper horizons in St. Petersburg using traditional and new methods of biological diagnostics has been studied for 4 years. Hydrobionts, higher plants and microorganisms were used as testing cultures. Sensitivity range of tested organisms towards anthropogenic impact was composed. The seasonal character of ecotoxicity dynamics for the most kinds of soils was determined. It was also detected that natural processes effect urban soils’ toxicity.

Evaluating the effectiveness of the process aerosol pesticide use software and information center The results of the use of software and information center for the evaluation of environmental parameters of aerosol spraying of pesticides.

Differentiation of ground invertebrate communities in urban environment (Kaluga, Russia) We have collected arthropods with pitfall traps and identified them to order or to family. Classification of arthropod communities reflects habitat properties, if we survey herpetobionts sensu lato (as biocenotic layer). And there is no satisfactory classification, if we consider herpetobionts sensu stricto (as life form). Differentiation of arthropod communities in urban area is influenced mainly with density of canopy.

Phylogeography of house mice Mus musculus in Russia and adjacent territories and role of invasions Using a phylogeographical approach based on the reconstruction of mitochondrial DNA, we attempt to determine the expansion and genetic diversity of different subspecies of M.musculus in Russia and adjacent territories. The study of genetic distances demonstrated existence of two phylogenetic lineages of Mus musculus distribuited in Russia and adjacent territories. The first lineage includes the house mice of Transcaucasian hybrid zone and populations of M.m.musculus subspecies from Moscow region, the second ones include populations of subspecies M.m.musculus and M.m.wagneri from the south of West Siberia and the south of Volga river region.

Characterization of cell growth and accumulation of phenolic compounds in suspension culture of Trigonella foenum-graecum L. The paper presents a characteristic of cell growth activity and synthesis of phenolic compounds in suspension culture of Trigonella foenum-graecum L. during its cultivation. It was shown that the suspension culture is characterized by the typical S-shaped type growth and high viability. Predominant types of fractions are single cells and small aggregates. The suspension culture accumulates phenolic compounds, mainly phenolic acids, throughout the growth cycle.
