The study was conducted on 20 Polish Merino ram-lambs divided into two groups: experimental (E) and control (C), each of 10 animals. From birth all the lambs were maintained with their dams and then weaned at the age of 8 weeks, placed in individual straw-bedded pens and fattened individually with a granulated concentrate mixture until reaching a mean body weight of 31.8 kg. During fattening ea...

BACKGROUND Patients who undergo hemodialysis experience accelerated atherosclerosis and premature death. Recent evidence suggests that endothelial dysfunction proceeds to and exacerbates atherosclerosis. It remains unknown whether hemodialysis per se causes endothelial dysfunction. METHODS AND RESULTS We evaluated endothelial function estimated by flow-mediated vasodilation during reactive hy...

The study was conducted on 40 Polish Merino ewes divided into two groups: experimental (E) and control (C), each of 20 animals. Four weeks before, and then on day 1, week 3 and week 6 post lambing all ewes from group E were given intramuscularly 5 ml 0.1% Na2SeO4, 10 ml 10% ZnSO4 and 250 mg vitamin E. In milk sampled 7 weeks after lambing the concentration of conjugated linoleic acid (0.66% of ...

Two well-known antioxidative nutrients, vitamin E and selenium, were used in this study to investigate possible inhibitory action against the formation of esophageal adenocarcinoma (EAC) in rats. In this model, carcinogenesis is believed to be driven by oxidative stress. Male Sprague-Dawley rats (8 weeks old) were divided into four groups and received esophagoduodenal anastomosis (EDA) surgery ...

The aim of the present study was to evaluate the indicators of oxidative stress (malondialdehyde [MDA]) and antioxidant status (ferric reducing ability of plasma [FRAP]; superoxide dismutase [SOD]; glutathione peroxidase [GSH-Px]; selenium [Se]; vitamin E) in dairy cows of the Slovak Pied cattle from 3 weeks before parturition to 9 weeks after parturition. The mean MDA concentration was signifi...

background: the pathogenesis of atopic dermatitis (ad) remains to be determined; recently a possible change in the immune system with production of immunoglobulins is proposed. as vitamin e is a potent antioxidant, with the ability to decrease the serum levels of immunoglobulin e (ige) in atopic patients, we aimed to evaluate the effect of oral vitamin e on treatment of ad.materials and methods...
