Study of geochemical features of soils on the territory of an abandoned coal mining area using geoinformation technologies.

The article describes the results of a study of the geochemical features of soils on the territory of an abandoned mining area. The Kizel coal basin (Russia) is of particular interest for studying the consequences of technogenic and post-technogenic transformation of the natural environment. The study of the soil as a deposit medium made it possible to identify geochemical indicators of the negative impact.

Ecological criteria for assessing the content of petroleum hydrocarbons in the main soils of coniferous-deciduous forests and forest steppe.

The effect of pollution of Albicluvisols/Retisols, Calcaric Leptosols, Luvic Phaeozems, Greyzamic Phaeozems and Folic Fluvisols with oil (Solovatovsky oil field, Perm region) added in amounts of 1, 2, 3 and 5 g oil/kg of soil on the organisms was studied in a model laboratory experiment. Oil addition showed phytotoxic effects on root length in Triticum aestivum L., Lepidium sativum L.

[Pathogenetic therapy of tuberculosis of respiratory organs during sanatorium-and-spa treatment].

The objective of this study was to evaluate the efficiency of combined inhalation of cycloferon for 5 weeks and oral intake of cytoflavin during the period of sanatorium-and-spa treatment of the patients with pulmonary tuberculosis. It was shown that combined immunotrophic and antioxidative treatment promotes resolution of focal and infiltrative lesions in the lungs, normalization of hemograms, and minimization of the activity of cytolytic and cholestatic markers of the liver.

[Molecular-genetic detection of a nonpathogenic genotype of Spironucleus barkhanus (Diplomonadida: Hexamitidae) in the black Baikal grayling (Thymallus arcticus baicalensis Dybowski, 1874)].

A nonpathogenic genotype of Spironucleus barkhanus (Diplomonadida: Hexamitidae) has been revealed for the first time in the Baikal grayling (Salmoniformes: Thymallidae) by molecular-genetic methods. Sequences corresponding to a fragment of the gene encoding the small ribosomal subunit RNA (SSU rRNA) have been obtained. The genotype of S.
