Modern overview of biochemical mechanisms of pathogenesis of diabetes mellitus type 2

Abstract

In forest ecosystems of Ukraine 137Cs content in macromycetes is up to 2-fold higher than in forest litter (which during the all post-Chornobyl period is the main depot of radionuclides). That is why it is possible to use them for bioindication of radiocaesium contamination. Between mushroom species investigated we have defined some species as hyperaccumulators of 137Cs, these include certain representatives of mycosymbiotrophic families Cortinariaceae, Russulaceae, Boletaceae, Paxillaceae, Hydnaceae і Gomphidiaceae. For the long-term monitoring of 137Cs it is recommended to use widely spread in Ukrainian forest ecosystems species-bioindicators such as: Xerocomus badius (Fr.:Fr.)Kühn. ex Gilb., Lactarius rufus (Scop.:Fr.) Fr. і Paxillus involutus (Batsch.:Fr.) Fr. Accumulation of 90Sr in wild growing mushrooms is not as high as radiocaesium. Samples of the fruiting bodies from the 10-km zone of ChNPP are showing a range of 137Cs/90Sr from 7.5—10000. Data of 137Cs content in macromycetes-bioindicators will allow to forecast the levels of contamination in soils, other wild mushrooms and berries.
