[Peculiarities of saliva chemiluminescence and microelement hair content in children with various dental caries activity].

Integrated stomatological examination of 1002 children of Khabarovsk Territory was conducted. Besides carious process and oral hygiene indices the intensity of free radical oxidation in saliva (by chemiluminescence method) and basic microelement hair content (by spectral analysis method) in urban and rural children with compensated and decompensated forms of dental caries. High and equal prevalence and incidence of dental caries in urban and rural children was found. It was shown that in cases of decompensated forms of dental caries indicators of saliva chemiluminescence and consequently the intensity of free radical oxidation was significantly higher than in cases of compensated forms of dental caries. It was determined that activation of free radical oxidation with dental caries progression was developed on the background of combined deficit and imbalance of essential microelements.

[Non-flame atomic absorption method of the analysis of mercury-containing biological materials]. / Neplamennyi atomno-absorbtsionnyi metod v analize rtut'soderzhashchikh biomaterialov.

Julia-2 mercury analyzer is modified. Gasodynamic scheme of the device is altered: water vapors can no longer enter the cuvette, the circulation mode is realized. Equilibrium concentration of mercury vapors is thus attained. The analytical signal is well reproduced. Alteration of the reactor volume improves the sensitivity of testing larger samples.
