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.

[The parasite fauna of the big and little Baikal oil fishes].

The parasite fauna of two endemic fish species of the genus Comephorus (Cottoidei: Comephoridae) includes 11 species. Six species were found in Comephorus baicalensis and 9--in C. dybowskii.

[Role of high-dose BEAM-chemotherapy and autologous hemopoietic stem cell transplantation in the treatment of drug-resistant Hodgkin disease].

In 1995-1999, 67 patients with relapsed Hodgkin's disease or refractory to chemotherapy (group A--first relapse, B--primary refractory disease, and C--repeated relapse) received cytoreductive (dexaBEAM, DHAP) therapy followed by high-dose BEAM chemotherapy and autologous bone marrow or blood cell transplantation. Early postoperative transplant-related mortality rate was 4.5%.

[The determination of the species classification of Baikal planarian cocoons found in the stomach of the black grayling (Thymallus arcticus baicalensis) by a comparative analysis of the nucleotide sequences of the ribosomal RNA gene].

Comparative analysis of nucleotide sequences of gene 18S of ribosome RNA was carried out. The results show that the genetic sequences of the given locus could be used as a molecular marker to identify the species of planaria irrespective of ontogenetic stage. The articles deals with problem of specific determination of cocoons of Baikal planaria from the stomach of Baikal black grayling using comparative analysis of nucleotide sequences of ribosome RNA fragments with known sequences determined earlier for Baikal planaria.

[Experience in the use of allogeneic bone marrow transplantation in severe forms of aplastic anemia at the Byelorussian hematological center].

Aim: Investigation of the response to antilymphocytic globulin (ALG) and transplantation of allogenic bone marrow (TABM) in patients with a severe form of aplastic anemia (AA).

Materials And Methods: 15 patients were treated for severe AA in 1995-1997. 8 patients of group 1 were given ALG/cyclophosphamide with subsequent TABM from HLA-identical sib donor.
