Oznaczono zawartość glinu oraz podstawowych biopierwiastków Ca, Mg, Zn, Cu, Fe w kości udowej i wątrobie zwierząt doświadczalnych, u których wywoływano kumulację glinu w tkankach, a następnie poddano działaniu deferoksaminy. Poszukiwano zależności między stężeniem glinu a poziomem biopierwiastków w badanych tkankach oraz zmiany wywołane działaniem deferoksaminy - chelatora glinu.

EN

To assess the effect of aluminium intoxication in tissues of experimental animals on Ca, Mg, Zn, Cu, and Fe concentration, aluminium nitrate was administered intraperitoneally to mice at a daily dose of 0.27 mMol/kg for 5 weeks. Concentration of Al, Ca, Mg, Zn, Cu, and Fe were analyzed by atomic absorption spectrometry. The Al content in liver and tibia was significantly higher in treated mice in comparison with control group. In Al loaded tissues the significant increase of all tested essential elements was found. To evaluate the results of DFO treatment on essential elements, mice received 6 times intraperitoneally 3.5 mMol/kg of DFO. This treatment had generally no effect on reduction of Al concentration in tibia and liver, as well as on changes in essential elements concentration.
