[Classification of thyroid gland disease on the basis of selenium concentration in serum].

The aim of this study was to estimate the concentration of total selenium in serum women with thyroid gland disease. Selenium was determined by atomic absorption spectrometry using the hydride generation method (HG-AAS). Research was determined in 94 patients with thyroid gland disease and in 28 healthy controls.

Serum selenium concentration in patients with Wilson's disease.

Background/aims: Wilson's disease is a genetically determined disorder of copper metabolism in the liver. Due to the toxic accumulation of this trace element, body organs are damaged by free radical generation, lipid peroxidase and inhibition of synthesis of some proteins. Behavior of anti-oxidative factors in Wilson's disease has not been completely evaluated yet.

[Selenium concentration in serum of women with thyroid gland disease].

The aim of this study was to estimate the concentration of total selenium in serum women with thyroid gland disease. Selenium was determined by atomic absorption spectrometry using the hydride generation technique (HG-AAS). Selenium was determined in 30 patients with thyroid gland disease and in 12 healthy controls.

[Silicon forms and its role in infant food].

This paper presents an attempt to assess the total content of silicon and its potentially bioavailable forms to the baby body in milk nutrient and baby foods. The measurements of the total and bioavailable silicon were conducted with the use of two analytical methods. The method of atomic absorption spectroscopy (AAS) was used for the determination of total silicon content.
