The study was performed on pregnant ewes and their progeny. The experimental group of ewes was given injections of 5 mg selenium in the form of sodium selenite. The sodium selenite s.c. injections resulted in monre than a triple, significant increase in the selenium level in ewes, at the first month as compared to the initial concentration of 0.42±0.11 to 1.38±0.21 μmol/l. Also in lambs a marked increase in selenium was noticed in the first and fifth weeks of life, but the levels of this element were by a half lower than in their mothers. Moreover, considerable diminution of magnesium concentration was observed in both groups: from 1.05±0.05 to 0.82±0.07 mmol/l in Group 1 of ewes in the second month following Na₂SeO₃ injection, and from 0.94±0.05 to 0.82±0.08 mmol/l in lambs, in the ninth week.

The Premenstrual Syndrome (PMS) is described as a cyclical disorder related to the hormonal changes during a menstrual cycle, which affects the emotional and physical health of many women during their reproductive period of life. The PMS can obviously change the quality of life. The syndrome is characterized by a complex group of symptoms, such as depression, irritability, mood swings, anxiety, abdominal discomfort. These signs occur during the luteal phase of a menstrual cycle and disappear after the onset of menses. Some studies suggest that a variety of nutrients may play an important role in the mood swings which occur cyclically during the course of the premenstrual syndrome and that some can have a beneficial impact, especially on the estrous phase of a menstrual cycle. The aim of the paper is to review the results of some studies concerning the role of bioelements in patients with the PMS. Concentrations of magnesium, zinc, selenium and manganese are the highest during menses and the lowest in the ovulatory phase. Fluctuations of the magnesium concentration during a menstrual cycle and the involvement of this element in many cellular pathways and neuromuscular activities obviously affect the incidence or intensity of the PMS symptoms. However, we lack firm evidence that magnesium supplementation can have a positive effect on alleviating the the PMSrelated ailments. Some relationship between the PMS and bone demineralization or depressed calcium concentration in blood has been identified. However, further studies are necessary to examine how the calcium concentration in a human body can decrease the intensity of the PMS symptoms.

Selenium concentrations in the liver, kidneys, and muscles of silver foxes living at a farm in West Pomerania, (northwestern Poland) were determined. The studies were performed on 243 tissue samples collected from 81 foxes. Selenium concentration was determined using the modified Watkinson's spectrofluorometric method. The highest Se concentration was found in the kidneys, with a mean level of 0.587 µg/g of wet weight. In the liver, the mean level was 0.247 µg/g w.w. and in muscles 0.070 µg/g w.w.

The aim of this study was to determine the effect of exploitation of recreation horses horse in the summer season on the selenium concentration in serum and the values of chosen haematological parameters. Blood to analyse was sampled from horses used in recreation in two horse riding centres located in the Western Pomeranian Province. Stable 1 (8 horses), situated in a seaside resort, with rides being led mostly in a riding arena, less often in the field. Large rotation of riders with different level of riding advancement has been observed, with prevalence of novice riders and horses working on the lunge. Stable 2 (18 horses), situated in a rural area, far away from large cities; in the holiday season, horses work maximum 4 hours a day, with prevalence of rides of weak and moderate intensity, being led in the field, with riders with average and high level of riding advancement and small rotation of riders. Blood samples were drawn twice: in the first days of July (start of the holiday season) and in the last days of August (end of the holiday season). Average selenium concentration in the blood serum of horses in Stable 1 decreased significantly during the holiday season. Mean values of chosen analysed haematological parameters of the horses in both riding centres did not undergo any significant changes during their use in the holiday season. Significant increase in the leukocyte and platelet counts after the holiday season was observed in the blood of horses in Stable 1. The horses of Stable 2 were characterised by significantly higher mean haematocrit value (39.14%) when compared to those in Stable 1. No significant correlations were found between the Se concentrations and chosen haematological parameters. The observations being carried out confirm the occurrence of Se deficiencies in horses in the Western Pomerania. As it appears from the performed study, intensive recreational horse use (5-6 hours of work per day) affects the significant decrease in serum selenium concentration, which suggests that application of appropriate supplementation in the nutrition of intensively working horses is necessary. Insufficient number of studies and ambiguous results concerning the effect of horse use on the WBC and the platelet counts prompt to undertake more broader observations in this respect.

Selenium is an essential element for humans, animals and some species of microorganisms. In higher plants, however, the role of selenium is still unclear. Because selenium enrichment may influence the nutrient balance of plants, a study was done to test the effects of selenite-Se (Na2SeO3⋅5H2O) on selected macronutrients content in maize (Zea mays L. var. saccharata Kcke. cv. Złota Karłowa) seedlings. Plants were grown in Hoagland I nutrient solution (pH 6,2) amended with selenite at 0 (control), 5, 25, 50 and 100 μmol⋅dm-3 for 14 days. The dry weight of the shoots was then analyzed for phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) content. Phosphorus and calcium content increased, while potassium content decreased with increasing selenium treatments. No significant differences were found for magnesium level. Plant growth was affected by excessive selenium concentration. At low concentration (5 μmol⋅dm-3), selenium tended to stimulate the plant growth and the root elongation but at higher concentrations (50 and 100 μmol⋅dm-3) the dry mass accumulation and root tolerance index severely decreased. The study revealed that disturbances of growth and reduction of plant’s biomass at the presence of high selenium concentrations in the nutrient solution may have resulted from the disturbance of mineral balance of plants, namely accumulation of large amounts of calcium and phosphorus in shoot tissues.

Concentration of selenium in serum samples was determined using a modified Watkinson's spectrofluorometric method. Selenium concentration averaged 0.021 ±0.008 µg/mL for water buffaloes and 0.074 ±0.017 µg/mL for dairy cows. The analysis of selenium concentrations in cows showed deficiency level in 2.0%, marginal level in 64%, and optimal level in 34% of the examined samples. In water buffaloes, deficiency level was found in 96.55% and marginal level in 3.45% of the animals. Selenium levels in cattle and water buffaloes should be periodically diagnosed to provide data for veterinarians to make appropriate decisions. The implementation of suitable prophylactic programmes will enable optimum levels of this element to be maintained.

Aim: Selenium (Se) is of fundamental importance to health conditions. Also, the concentration of Se in human organism depends on dietary intakes. The aim of this study was to analyze the influence of dietary preferences on serum and tissue levels of Se in patients with laryngeal cancer. Methods: Twenty eight patients who had undergone an operation on laryngeal cancer, were studied. Food frequency questionnaires were implemented to collect the dietary> data Serum and tissue levels of Se were determined using atomic absorption spectrometry. Results: In patients with laryngeal cancer the mean Se concentration in serum (38.73±13.9 µg/L) and cancer tissue (94.00± 92.7 ng/g) were significantly lower than in controls (52.56 ±12.8 µg/L and 174.01±120.9 ng/g, accordingly). Smoking and using butter on bread decreased Se levels in tissue of cancer sufferers. Frequent consumption of pork-butcher 's meat increased of Se concentration in serum and cancer tissue, but honey only in serum. Conclusion: Se levels in patients with laryngeal cancer may depend not only on the health condition, but also on the habit of eating pork-butcher 's meat, butter and honey. It can also depend on the fact if a patient smokes or not.
