The systematic and quantitative composition of Actinomyces (genus Streptomyces) in the soils of Kaliningrad was analysed according to the level of soil contamination. The authors proved the seasonal activity of Actinomyces in the soils of the city and identified the changes in the dependence between the number of Actinomyces and the temperature and pH of soil environment
throughout seasons. The article offers a preliminary systematic analysis of Actinomyces in the city soils.

This article analyses the level of antioxidants (water-soluble antioxidants, carotenoids, and anthocyanins) in plants under the conditions of environmental cadmium pollution. The authors emphasise excessive background concentration of cadmium in plant samples collected in Kaliningrad and note a positive correlation between cadmium concentration and traffic intensity. A negative
correlation between the Cd content and the antioxidatic status of plants and a positive one with the anthocyanin content were established in the course of research.

This article focuses on the features of corrosion of St. 3 steel in water-salt media containing sulfate-reducing bacteria. The authors emphasises the biocide and inhibitor role of a number of organic substances in the course of corrosion and hydrogen absorption of steel in presence of sulfate-reducing bacteria.

This article analyses the dynamics of sugar concentration in the nectar of Taraxacum officinale Wigg. in the arctic, boreal and temperate zones of Russia. The author arrives at the conclusion that the sugar productivity of flowers analysed changes throughout the day. The average sugar production in T. officinale flowers increases towards the North.

This article considers the morbidity of vector-borne infections in the Kaliningrad region against the background of regional climate change. The author points out the increasing prevalence of Lyme disease in 1995—2008 and emphasises the role of abnormal weather conditions in morbidity changes.

Upper limb injuries account for 50—70 % of orthopedic trauma incidents. The number of multisystem injuries is increasing. The author describes the frequency, structure, and extent of injuries to tendons and nerves on the basis of 400 cases. The article offers an analysis of the efficiency of pre-hospital surgical interventions. The statistical data obtained favour high-precision techniques of tendon and nerve treatment over the traditional ones. The author achieved relatively high positive results of treatment — 88,8 % of
patients were able to return to work.
