[INVESTIGATION OF IRON, ZINC, STABLE STRONTIUM AND LITHIUM CONTENT IN BIOLOGICAL FLUIDS AND TISSUES DURING EXPERIMENTAL SPACE FLIGHT SIMULATION].

In an experiment with space flight simulation, atomic emission spectral analysis with inductively coupled argon plasma was employed to measure iron, zinc, stable strontium and lithium in blood serum and its ultrafiltered fraction, and excretion with daily urine and hair. Monitoring of serum iron and its ultraviolet fraction showed good balance of these parameters in all periods of the experiment. Blood serum was found to contain exclusively iron bound with protein carriers.

[Age and gender characteristics of the content of macro- and trace elements in the organisms of the children from the European North].

By means of the nuclear-emission spectral analysis with inductively connected argon plasma were studied the contents of 28 macro- and trace elements (Al, Ag, Li, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, In, K, Mg, Mn, Na, Ni, Mo, P, Zn, Se, Tl, Pb, Sr, S, Si) in the hair of children and teenagers living in the European North of the Russian Federation (Arkhangelsk region). There were revealed both: decrease and increase of some elements' contents. Also were revealed the dynamics of mentioned elements contents in the hair of the same children in different years.

[Investigation of the copper content in blood serum and its ultrafiltrate in the conditions of experimental space flight simulation].

In experiment MARS-500 on remote space flight simulation, atomic emission spectral analysis with inductively coupled argon plasma was used to measure serum copper and its ultrafiltration fraction. It was shown that, in contrast to baseline data, the Cu serum level varied within the normal physiological boundaries throughout the entire simulation experiment. These variations were sync in all the serum samples.

[Magnesium level in human organism during 105-day isolation].

Total and ionized magnesium in blood serum and in daily urine were determined before (baseline values) and on days 30, 60 and 105 of the experiment with 105-d isolation and confinement (Mars-105)/ Magnesium in hair was investigated before (baseline values) and on day-105 of the experiment. The investigations were performed using atomic emission spectrometry with inductively coupled argon plasma. Changes in magnesium were most significant over the initial 30 days in the experiment.

[Macro- and micro-element balance in tissue of different organs of experimental animals during their physiological and accelerated (radiation) aging].

By the method of atom-emission spectral analysis with inductive combined argon plasma we researched the containing of Al, Cd, Co, Cu, Fe, Mg, Mn, Mo, P, Pb, S, Zn in lungs, liver, kidneys, spleen and hemispheres of brain of female mice CBA line, aged 26 month and 14 months, and on the accelerated radiation aging model composed of mice of the same age and gender. The process of accelerated radiation aging stimulates accumulation of Al in liver and in kidneys; decreasing of containing Cd in lungs and spleen and increasing it in liver; decreasing of containing Co in lungs and spleen and increasing it in kidneys; decreasing of containing Cu in spleen; decreasing of containing Fe in lungs; decreasing of containing Mg in liver; decreasing of containing Mn in lungs and spleen; decreasing of containing Mo in lungs and spleen and increasing of it in liver and kidneys; the containing of Pb is decreased in lungs and increased in liver; the containing of S is decreased in liver and kidneys, the containing of Zn is decreased in liver and spleen (p < 0.05).
