The influence of dietary conjugated linoleic acid (CLA) isomers (CLAmix) and/or Se as Na2SeO3 (SeIV) or selenized yeast (SeY) on the relative body weight gain (RBWG) of rats, pancreas weight, concentrations of CLA isomers and of other fatty acids (FA) in the pancreas were studied. For 6 weeks, female Wistar rats (aged 8 weeks) were fed ad libitum the Labofeed H diet enriched in 1.5% CLAmix, 0.2 ppm Se (LSe), 0.5 ppm Se (HSe) as SeIV (i.e. LSeIV or HSeIV, respectively), or SeY (i.e. LSeY or HSeY, respectively). Each group contained eight rats. The results documented that dietary LSeIV and CLAmix most effectively increased the RBWG of rats and feed conversion efficiency, while the diet with HSeIV most efficiently increased pancreas weight compared with the control rats. The diets enriched in CLAmix and Se as SeIV or SeY increased the sum of saturated fatty acids (SFA), the atherogenic SFA, A-SFA index, thrombogenic SFA (T-SFA), and the T-SFA index in the pancreas of rats compared with the control group. The diets containing CLAmix and Se as SeIV or SeY stimulated the accumulation of cis9trans11CLA, trans10cis12CLA, as well as the sum of all CLA isomers in the pancreas compared with rats fed the diet enriched in CLAmix. These diets increased the concentration of n-6 polyunsaturated FA (n-6 PUFA) and decreased the level of long-chain n-6 PUFA (Ln-6 PUFA) in the pancreas compared with the control rats and rats fed the diets with SeIV or SeY. The diets containing CLAmix and Se (as SeIV or SeY) increased the concentration of n-3 PUFA and Ln-3 PUFA in the pancreas compared with the control rats. Our study findings documenting that dietary Se and/or CLAmix and Se (as SeIV or SeY) considerably increased the concentration of PUFA, especially n-3 PUFA, improved the n-6 PUFA/n-3 PUFA ratio in the pancreas are valuable information for scientists carrying out research to improve animal and human health.

We investigated the effect of selenium form and dose on the total glutathione and non-protein -SH group contents in the edible spinach (Spinacia oleracea L.) and ground tomato (Lycopersicon esculentum Mill.) plants. Our experiments were carried out in a hydroponic culture. Selenium was added to the culture medium in its selenite (Na2SeO3 x 5H2O) and selenate (Na2SeO4) forms. Regardless of the selenium form, we observed an increase in the non-protein thiol content. The non-protein -SH group content depended on the form and dose of selenium as well as on the organ and plant species. Regardless of the selenium form, a higher content of non-protein -SH groups were found in the spinach biomass than in the tomato biomass. Selenite contributed to a larger accumulation of non-protein -SH groups in the roots, whereas selenate contributed to their accumulation in the shoots

W wątrobie, nerce i mózgowiu szczurów otrzymujących przez 12 tyg. wodę zawierającą 50 µg Cd2+ /cm3 i/lub dożołądkowo 5 µg Se/100 g masy ciała, badano aktywność dehydrogenazy glutaminianowej (GLDH), arginazy (ArgE), katalazy (CAT) oraz całkowitą zawartość wolnych aminokwasów (AmAc) i mocznika (Ur). Zatruwanie kadmem powodowało wzrost aktywności GLDH i ArgE w nerce i mózgowiu oraz zawartości mocznika w badanych narządach. Podawanie seleninu obniżało o kilkanaście procent zawartość Ur w nerce oraz aktywność CAT w wątrobie i nerce, nie wpływając na inne wskaźniki. Selen przeciwdziałał zmianom wywoływanym przez kadm z wyjątkiem zmian zawartości Ur w tkankach. Zawartość AmAc w narządach nie była zmieniana przez badane czynniki.
