Badania przeprowadzono na 27 pacjentach z guzem krtani. Wykazały, że zawartość kadmu w tkance guza wynosiła (75,969 ± 61,619ng/g) i była istotnie niższa niż w tkance okołonowotworowej (203,404 ± 123,003ng/g). Oznaczenia kadmu wykonano metodą atomowej spektrometrii absorpcyjnej z atomizacją elektrotermiczną w kuwecie grafitowej po uprzedniej mineralizacji techniką mikrofalową. Wykazano, że częste spożywanie słodyczy podwyższa zawartość kadmu w tkance guza. Nie wykazano wpływu palenia papierosów na poziom kadmu w badanej tkance nowotworowej i okołonowotworowej.
Background. Bakery products are a source of bioactive compounds, such as dietary fibre (DF), whose proper supply plays an important role in prevention of civilisation diseases. Objective. The aim of the present study was to determine total dietary fibre (TDF) content in bakery products and their contribution to TDF supply. Material and Methods. The determination of TDF content was performed using enzymatic-gravimetric method in 72 samples of six types of bakery products (wholemeal rye bread, wheat-rye bread, wheat-rye bread with grains, toast bread, crispbread, rolls) included in the young adults diet. Simultaneously, frequency of bakery products consumption and their contribution to TDF supply were assessed based on dietary interview questionnaires carried out among 224 students from Poland. Index of nutritional quality (INQ) of examined bakery products was calculated. Results. Our data indicate that average TDF content depended on the type of bakery products and ranged from 2.19 g/100 g in rolls to 11.80 g/100 g in wholemeal rye bread. All of the tested types of bakery products, except rolls, were a good source of fibre (INQ≥1), but the richest were wholemeal rye and wheat-rye with grains breads. Analysis of questionnaires data showed that bakery products were regularly consumed by 80% of young adults; however, most of whom preferred rolls. Consumption of bakery products covered current recommendations for dietary fibre in 27%. Daily intake of bakery products and TDF was not correlated with student’s BMI, however, women frequently consuming bread had a lower BMI than those who rarely ate it. Conclusion. Wholemeal rye and wheat-rye with grains breads are the rich source of TDF and they should be consumed by young adults in order to achieve the recommended TDF values.
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.
