[Biochemical processes of greenhouse gasses generation in swamplands of the Gorny Altai].

Starting from 2009, monitoring studies of swamp regimes have been conducted at the swampland station located in the north-eastern Altai. Here, we present the results of biological activity (indices of microorganisms abundance, respirometric indicator, catalase activity) in peat deposits of eutrophic (Turochak) and mesotrophic (Kutyushskoye) swamps during 2012-2013 vegetation periods with different levels of marsh water and oxidation-reduction conditions.

Cardioprotective Activity of Ganoderma lucidum Extract during Total Ischemia and Reperfusion of Isolated Heart.

The cardioprotective effects of Ganoderma lucidum extract were examined in experiments with global ischemia (45 min) and reperfusion (30 min) of isolated and perfused rat heart. The course of preventive administration of the extract in a dose of 400 mg/kg for 15 days diminished necrotic death of cardiomyocytes and reduced reperfusion contracture. Ganoderma lucidum extract demonstrated antioxidant properties.

[The structure of the micromycete complexes of oligotrophic peat deposits in the southern taiga subzone of West Siberia].

The analysis of the micromycete complexes of oligotrophic peat deposits in the Vasyugan Marsh by direct count and culture methods showed that the micromycete carbon comprises no more than 3% of the total peat carbon and that the microscopic fungal biomass varies from 2 to 13 tons/hectare, depending on the season and the peat deposit thickness. Fungal spores were found in all layers of the peat deposits, whereas the mycelium was found only in the active peat layer. The high abundance of eukaryotic cells in the peats was due to the presence of yeastlike cells rather than fungal spores.
