[Influence of age in content of trace elements in pharyngeal tonsils from exposure and unexposure children]. / Rola wieku w ksztaltowaniu sie obecnosci pierwiastków fizjologicznych w migdalakch gardlowych dzieci w aspekcie biernego palenia.

This project is aimed to estimate the effect of passive smoke on the levels of selected trace elements (Ca, Mg, K, Na) in pharyngeal tonsils of children in several group of age (2-5 years, 6-9 years, 10-15 years). This trace elements were determined using ICP-AES method. It was concluded that the exposure to the cigarette smoke in pharyngeal tonsils is a factor producing the changes in the levels of essential elements: geometric mean of Ca was the highest in pharyngeal tonsils of children in 10-15 years old unexposure to ETS (410 microg/g). The least level of Ca - 281 microg/g was observed in this samples in the same group of age, but in children exposure by ETS. High levels of K was observed in pharyngeal tonsils of children exposure to passive smoking in all of group of age to comparison to unexposure by ETS. The greatest content - 27479 microg/g was in pharyngeal tonsils in exposure to ETS in 6-9 years old was observed, but the least - 16478 microg/g in 10-15 years old. Change of content of Mg was from 764 to 784 microg/g in samples from children exposure by ETS to comparison 720-744 microg/g in children unexposure by ETS. High level of Na was observed in pharyngeal tonsils from children exposure to ETS in all of group of age to comparison to unexposure. This study showed that the kind of interaction dependent on age and exposed by ETS. The changes of given elements were different for children passive smoking and no passive smoking in several group of age.

[Trace elements concentration in pharyngeal tonsils from exposed and unexposed to ETS children in refer to sex and places of living]. / Wplyw biernego palenia na zawartosc pierwiastków fizjologicznych w migdalkach gardlowych w nawiazaniu do plci i miejsca zamieszkania.

The aim of this study was investigation influence sex and place living (industrial region or village) to concentration of: Ca, K, Mg and Na in pharyngeal tonsils (n = 84) from children exposed and unexposed to tobacco smoke and analysis kind of interactions between trace elements. Determination of these elements contents were performed by ICP-AES. It was found higher concentrations of Ca and Na in pharyngeal tonsils from boys (389 microg//g) and girls (356 microg/g) unexposed to tobacco smoke to comparison to expose to ETS boys (304 microg/g) and girls (298 microg/g). Higher concentrations of Ca and Na was found in this samples from children unexposed on ETS, living in industrial area to comparison to unexposed to ETS children living in village region. Higher concentration of K and Mg was found in exposed to ETS girls and boys in comparison to unexposed to ETS children, and higher level of these metals were found in exposed to tobacco smoke children living in industrial region and village.

Characteristics of chelation ability of chosen metal ions by protective ointments containing Na2H2EDTA.

Allergy contact dermatitis is a common occupational disease and the protective ointments are often used by the sensitized subjects. The efficacy of the chelation ability of the barrier creams containing Na2H2EDTA was evaluated. The in vitro test with the diffusion chamber and artificial membrane was performed. The effect of the Na2H2EDTA concentration (3, 5 or 10%), pH of the buffer for Na2H2EDTA dissolving and the vehicle of the ointment on the chelation of Ni2+ and Co2+ were assessed. The ointment with 10% Na2H2EDTA dissolved in the buffer of pH 7.0 or 7.4 buffer was found as optimal for the protection ability. There was no influence of the formula of the ointements on the efficiency of chelation.

[Accumulation of Cu in pharyngeal tonsils from children exposed and unexposed to smoke of tobacco]. / Kumulacja Cu w migdalkach gardlowych dzieci narazonych i nienarazonych na dzialanie dymu tytoniowego.

The characteristic of occurrence Cu content in pharyngeal tonsils from girls and boys exposed to tobacco smoke and unexposed to tobacco smoke living in Southern Poland is presented in this article. Analysis of content of Cu in pharyngeal tonsils was observed in eight groups of children: girls exposed to tobacco smoke and unexposed to tobacco smoke living in industrial region and village, boys exposed to tobacco smoke and unexposed to tobacco smoke living in industrial region and village. Geometric mean of contents of copper in pharyngeal tonsils from girls exposed to ETS living in industrial region was 1.35 microg/g and no exposed girls was 1.31 microg/g, in girls exposed to ETS living in village region was 0.72 microg/g and no exposed to ETS girls was 0.66 microg/g. Geometric mean of contents of copper in pharyngeal tonsils from boys exposed to ETS living in industrial region was 1.76 microg/g and no exposed to ETS boys was 1.10 microg/g, in boys exposed to ETS living in village region was 0.71 microg/g and no exposed girls was 0.30 microg/g and this differences was statistically important. The cross-correlation analysis between content of Cu and other metals Ba, Ca, Cr, Al, Fe, Mg, Mn, Zn, K, Na in eight groups of children was observed.

[Co-occurrence Fe in relationships to other metals in pharyngeal tonsil of children in view of sex, age and expose to passive smoking]. / Wspólwystepowanie Fe z innymi metalami w migdalkach gardlowych dzieci ze wzgledu na plec, wiek i narazenie na dym tytoniowy.

The aim of this study was analysis of kind of interactions between Fe and the other metals: Al, Ba, Ca, Cr, Cu, Mg, Mn, Zn, K i Na in pharyngeal tonsils from girls and boys in several group of age (2-5 years, 6-9 years and 10-15 years) exposed and no exposed to tobacco smoking. This study showed that the kind of interaction dependent on sex, age and exposed to ETS.
