An experiment was conducted using 20 male buffalo calves to study the effect of vitamin E and selenium supplementation on their immune response and plasma α-tocopherol and selenium status. These buffalo calves (10-12 months old, average body weight 75.30±2.20 kg) were randomly allotted to four treatments on the basis of their body weights and were fed on wheat straw and concentrate mixture to m...

Oxidative DNA damage may be important in mutagenic, carcinogenic, and aging processes. Although it is plausible that antioxidant vitamins may reduce oxidative DNA damage, evidence from human studies has been sparse and inconsistent. We determined the short-term effects of vitamin C (500 mg/day) and vitamin E (400 IU d-alpha-tocopheryl acetate/day) supplements on oxidative DNA damage in a double...

Chick embryo tissues contain a high proportion of highly polyunsaturated fatty acids in the lipid fraction and therefore need antioxidant defence (Surai, 1999). It is well accepted that maternal diet composition is a major determinant of antioxidant system development during embryogenesis and in early postnatal development. The antioxidant system of the newly hatched chick includes the fat-solu...

background: hyperthyroidism is associated with liver oxidative stress causing liver dysfunction in many hyperthyroid patients. the hepatoprotective effect of satureja khuzestanica essential oil (skeo), as herbal origin antioxidant and anti-inflammatory agent on the hyperthyroidism induced hepatotoxicity and oxidative stress is investigated. methods: adult male sprague dawley rats were divided i...

The effect of natural (NE) and synthetic vitamin E supplementation (SE) on lamb meat packed under modified atmospheres (MAP) for 14 days was studied. Three hundred and sixty Rasa Aragonesa lambs were offered nine dietary treatments (0, NE125, NE250, NE500, NE1000, SE250, SE500, SE1000 and SE2000). Lambs had ad libitum access to the experimental compound feed and wheat straw, for 14 days (pre-sl...

asthma is a chronic inflammatory airway disorder and the most common chronic disease among children characterized by frequent and chronic cough, wheezing, and dyspnea. asthma is defined as an inflammatory process in response to t- helper 2 cells. vitamin e as a lipid soluble vitamin containing 4 isomers α, β, γ, б, with α- tocopherol as the most important isomer is an important defensive agent ...

Sixteen Yorkshire gilts were assigned randomly to four semi-purified diets fed throughout gestation and lactation. Two sources of fat (stripped lard and stripped corn oil) were fed factorially with two levels of vitamin E (atocopheryl acetate, 0 and 100 IU/kg of diet). All diets were supplemented with .05 ppm Se as Na2SeO3. Reproductive performance (litter size, individual pig birth weight, wea...

Background: Cyclosporine A (CsA) is a nephrotoxic immunosuppressive drug. Antioxidants might attenuate its toxicity. In the present study, the effects of vitamin E and quercetin on the morphology of kidney in CsA-treated rats were investigated. Methods: Six groups of rats were used in this gavage feeding study either for 4 or 8 weeks. Groups 1 and 2 received either olive oil or 25% ethanol in o...
