The effect of selenium supplementation on polyunsaturated fatty acids in rat
Crespo, A.M.V.; Lança, M.J.; Reis, M.A.The purpose of this work was to study plasma, adipose tissue, and liver fatty acids percentages of Wistar rats that drank water supplemented with several levels of sodium selenite for 1, 3, and 6 mo. In a general way, percentages of saturated, monounsaturated, and polyunsaturated fatty acids of supplemented groups were not different from those obtained with nontreated animals in the analyzed tissues. However, i...
Effect of selenium supplementation on some blood biochemical parameters in male...
Crespo, A.M.V.; Lança, M.J.; Vasconcelos, S.; Andrade, V.; Rodrigues, H.; Santos, M.C.The long-term effect of selenium supplementation on blood glutathione peroxidase (GSH-Px) activity and plasma TBARS’ production (as an index of peroxidation) was evaluated in 15-mo-old male rats fed a diet supplemented with 0.25 or 0.50 ppm selenium, for 12 mo. A group of nonsupplemented age-matched rats was the control. In addition, triglycerides, phospholipids, total and free cholesterol, HDL-cholesterol, and...
The effect of age and selenium on some biochemical parameters in rat liver
Santos, M.C.; Rodrigues, H.; Vasconcelos, S.; Andrade, V.; Lança, M.J.; Crespo, A.M.V.Two age groups, 3 and 15 mo, were used to investigate whether age-associated changes in some parameters related to lipid peroxidation occur in the liver of male Wistar rats and to observe possible effects of dietary selenium supplementation (0.25 and 0.50 ppm) for 12 mo on the same parameters. At these experimental conditions, the most important observation was that peroxidation did not change by aging, at leas...
