Evaluation of selenium status and its distribution in organs of free living foxes (Vulpes vulpes) from an Se deficient area.

The objective of the study was to determine selenium status and its distribution in the organs of free living foxes from selenium deficient areas of north-western Poland. Samples of organs harvested from 40 foxes shot during the 2008-2009 hunting seasons served as experimental material. Selenium concentration in the organs was determined spectrofluorometrically.

Relationship between selenium and selected heavy metals concentration in serum of cattle from a non-polluted area.

The present study was undertaken to evaluate the concentration of selenium and selected heavy metals and their possible relationship in serum of 25 healthy lactating cows (Montbéliarde) reared in a non-polluted area, in the western part of Poland. Cadmium, lead, copper, and zinc concentrations were determined by inductively coupled plasma-atomic emission spectrometry and Se concentration was determined fluorimetrically. The content of Se, Zn, and Cu was 0.

Glutathione peroxidase (GSHPx) activity in the liver of red deer in relation to hepatic selenium concentrations, sex, body weight and season of the year.

The purpose of this study was to determine glutathione peroxidase (GSHPx) activity in the liver of red deer in relation to selenium concentrations in the liver, as well as to evaluate changes in GSHPx activity according to sex, body weight and season of the year. Total selenium concentration in the liver of red deer averaged 0.095 ± 0.

Tissue distribution of selenium and effect of season and age on selenium content in roe deer from northwestern Poland.

The aim of the study was to compare selenium concentrations in different organs of roe deer from northwestern Poland. Samples of liver, kidneys, heart and lungs, collected from 74 roe deer shot during the hunting seasons of 2008-2009 in northwestern Poland, were studied. Selenium concentration in the organs was determined spectrofluorimetrically.
