For today it is known, that primary and secondary disorders of the aerobic respiration, which are based on mitochondrial deficiency, lead to a wide spectrum of clinical manifestations and diseases. Therefore, the question about effectiv. correction of v.rious types of energy exchange disorders remains topical. Thus, the aim of our work was the study effect of the complex of biologically activ. substances (BAS) in ultra low concentrations on the activ.ty of key enzymes of aerobic energy metabolism succinate dehydrogenase (EC 1.***.99.1) (SQR) and mitochondrial glycerol-3-phosphate dehydrogenase (EC 1.***.99.5) (GPD2). The human lymphocytes assays were tested in v.tro (22 donors). In negativ. control lymphocytes, cell culture normal saline solution was added. Normal saline solution with NaN3 was added in positiv. control lymphocytes cell culture. Experimental cell culture contained NaN3 and BAS. Our inv.stigations had been rev.aled increase SQR activ.ty in the experimental cell culture as compared with positiv. control culture throughout the time of experiment (measurements were carried out at 4, 24, 48, 72 h of incubation). The SQR activ.ty of experimental cell culture and negativ. control lymphocytes cell culture was equal up to 24 h of experiment. It showed neutralization of NaN3 inhibitory effect (during 24 h) due to BAS influence. Activ.ty of base glycerophosphate shunt ferment GPD2 of experimental lymphocyte cell culture was not different from GPD2 index in the negativ. control, but was lower than GPD2 activ.ty in the positiv. control. It also indicated neutralization NaN3 inhibitory effect due to BAS influence. So we had found that extremely low concentrations of selected BAS with their complex impact on human lymphocytes in v.tro could effectiv.ly neutralize the inhibitory effect of NaN3 on processes of aerobic energy metabolism link.

Ion heat transport in electron cyclotron resonance heated L-mode plasma on the T-10 tokamak

Anomalous ion heat transport is analyzed in the T-10 tokamak plasma heated with electron cyclotron resonance heating(ECRH) in second-harmonic extra-ordinary mode. Predictiv. modeling with empirical scaling for Ohmical heat conductiv.ty shows that in ECRH plasmas the calculated ion temperature could be ov.restimated, so an increase of anomalous ion heat transport is required. To study this effect two scans are presented: ov.r the EC resonance position and ov.r the ECRH power. The EC resonance position v.ries from the high-field side to the low-field side by v.riation of the toroidal magnetic field. The scan ov.r the heating power is presented with on-axis and mixed ECRH regimes. Discharges with high anomalous ion heat transport are obtained in all considered regimes. In these discharges the power balance ion heat conductiv.ty exceeds the neoclassical lev.l by up to 10 times. The high ion heat transport regimes are distinguished by three parameters: the ratio Te/Ti, the normalized electron density gradient R/■, and the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and R/■=6-10 results in v.lues of normalized anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.

Studied waters belong to warm （T=30-50℃）, alkaline （pH=8.9-9.3）, low mineralized （TDS〈235 mg/l） Na-HCO3 or Na-SO4-HCO3 thermal waters with high content of SiO2 （up to 81 mg/1） and F （up to 3.9 mg/l）, occur on modern v.lcano-tectonic rejuv.nated areas of Eastern Sikhote-Alin orogenic belt. Low 3He concentration as well as N2/O2 and N2/Ar ratios exclude influence of deep mantle fluid. New rare earth element data constrain our understanding of water-rock interaction occurring in the water source region. Meteoric origin of waters is prov.d by stable isotope v.lues v.rying from -71%o to -136.1‰ and from -10.8‰ to -18.8%o for δ^2H and δ^18O respectiv.ly. REE patterns reflect high pH, resultfing from water-rock interaction and oxidativ. conditions. Calculations of deep aquifer temperature using Na-K and quartz geothermometers show 116.8-131.1℃ and 82.2-125.8℃ respectiv.ly. Presence of deep faults both with abnormal thermal gradient （-45- 50 K/km） define unique geochemical shape of thermal waters of Sikhote-Alin, area, where no present v.lcanic activ.ty is registered.
