An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

The relation among glutathione-related enzyme activities, thiobarbituric acid-reactive substances of the human aorta and internal mammary artery, and serum lipids was studied in 40 male patients undergoing coronary revascularization. Glutathione peroxidase and glutathione reductase activities were significantly higher in the internal mammary artery, whereas glutathione transferase activity was ...
By isolation of a mixed disulfide product of glutathione and cysteine, glutathione peroxidase was shown to be highly specific for only one donor substrate. Using the coupled assay of NADPH and yeast glutatione reductase, which is highly specific for flutathione disulfide, it was shown that the apparent inhibition of glutathione peroxidase by mercaptoethanol can be described kinetically and that...
Twenty-one pregnant women living in Xichang County, China, a selenium-deficient area, were divided into two groups and given either a placebo (n = 10) as yeast or selenium-enriched yeast tablets (n = 11) to provide 100 microg selenium per day. This supplementation was begun the last trimester of pregnancy and continued for 3 months after parturition. Plasma selenium levels and glutathione perox...
The concepts of oxidative stress and antioxidants have been implicated in neurodegenerative disorders. Oxidative stress was assessed by estimating lipid peroxidation product in the form of thiobarbituric acid reactive substances (TBARS). Enzymatic antioxidants like superoxide dismutase(SOD), glutathione peroxidase(GPx), catalase, ceruloplasmin and non enzymatic antioxidant vitamins like vitamin...
The objective of this experiment was to compare the efficiencies of sodium selenite (SS) and selenized yeast (SY) supplemented at different doses (0.05 and 0.30 mg Se/kg feed) with respect to plasma glutathione peroxidase (Gpx) activity, extent of oxidative lipid injury, and thyroid hormone activation in broilers during the first four weeks of growth. Results indicate a significant increase in ...
Oral administration of cadmium (6mg/kg body weight/day) as cadmium chloride (CdCl2) for 30 days resulted in a significant increase in thiobarbituric acid reactive substances (TBARS) level and a decrease in the levels of copper, zinc, iron, selenium, glutathione, superoxide dismutase, catalase, glutathione peroxidase when compared to normal control. Administration of either Liv-52 alone or in co...
The aim of this study was to assess the lipid peroxidation in chronic leg ischaemia by determining thiobarbituric acid reactants. Furthermore, Cu, Zn-superoxide dismutase and glutathione peroxidase activities as well as the trace element profile (Zn, Cu, Se, Mg) were determined. Fasting blood samples from the common femoral artery and vein were taken from both legs of 15 patients (57 +/- 7 year...
The importance of selenium for organisms can be explained by its existence as selenocysteine in the catalytic centers of glutathione peroxidase and thioredoxin reductase. Another selenoamino acid, selenomethionine, is the major form of selenium in foods, and organisms that require selenium as a nutrient directly metabolize selenomethionine to a reactive form of selenium or store it in general p...
