The assimilation of phenol as a sole source of carbon and energy was studied with the thermophilic bacillus isolated from the geothermal zones in the South Ural. This ability was displayed by 11 strains of Bacillus stearothermophilus among 26 studied strains. The most active strains oxidized all phenol, when its content in the medium was 0.1--0.2%, during(More)
B lymphocytes. Marked stimulation of the rosette-forming capacity of the neutrophils and restoration of the lysozyme level were noted. Taken as a whole, these observations point to an increase in total functional activity of the neutrophils, and they are in agreement with data published previously [8-10]. Thus in acute destructive pancreatitis inhibition of(More)
The influence of mitogens on the expression of surface membrane TC-II receptors of human blood lymphocytes and internalization of (TS-II+57Co-CNCbl) complex into cytoplasm were investigated. Mature lymphocytes have a very small number of surface receptors to plasma TC-II but their expression is increased significantly by PHA or Con-A stimulation. CBl(More)
The cell wall of Blakeslea trispora was found to contain chitin similar to crustaceaous chitin in physico-chemical properties; this was confirmed by the data of IR spectroscopy and X-ray diffraction analysis. Trisporic acids, hormonal regulators of reproduction, hardly affected the content of chitin, xylan, and other polysaccharides of the cell wall of(More)
Transcobalamin II (TcII) level was studied in plasma of 40 children with acute leukemia. TcII is a cobalamin-binding protein which mediated the cellular uptake of Cbl and interacted with surface membrane receptor of hemopoietic cells. Plasma TcII and cobalofilins were analysed by PAGE using 57Co-cyanocobalamin. In addition, the mature human placenta with(More)
A decisive role in the mechanism of the supply of cobalamin coenzyme precursors to cells, which are essential for their normal proliferation and maturation, is played by the formation of a transcobalamin-II cobalamin complex (TC-II+Cbl) with the membrane surface receptor. Specific receptors of this type have been found on cells of the villi of the mature(More)
Serum protein transcobalamin II (TC-II) is responsible for transport of cobalamins into mammalian cells. A method of quantitative estimation of plasma membrane receptors of hemopoietic cells to TC-II cobalamin complex is suggested. Analysis of mouse leukemia L1210 cells includes the saturation of radiolabelled ligand-receptor complex with papain. The number(More)
The influence of inhibitors of different lipoxygenases (LOX) on the growth of human tumor cells with different profiles of synthesized eicosanoids was studied. The studied LOX inhibitors had virtually no influence on the growth of A549 cells actively synthesizing cyclooxygenase and lipoxygenase metabolites of arachidonic acid (AA). The inhibitor of 12-LOX,(More)
