Effects of vitamin E and selenium on immune responses of peripheral blood, colostrum, and milk leukocytes of sows.

Effects of selenium and vitamin e supplementation on concentrations of selenium and immunoglobulins in colostrum and blood of baluchi ewes and lambs and on lamb growth

Adverse Effect of T-2 Toxin and the Protective Role of Selenium and Vitamin E on Peripheral Blood B lymphocytes

Background: T-2 mycotoxin belongs to the Trichothecene family and has damaging effects on the immune system. Objective: To investigate the toxic effect of T-2 toxin on the percentage of peripheral blood B lymphocytes and the potential protective role of selenium and vitamin E. Method: Frequencies of B lymphocytes (CD19+ ) were analyzed after injection of sublethal doses of T-2 toxin into Balb/c...

Radioprotective effects of selenium and vitamin-E against 6MV X-rays in human blood lymphocytes by micronucleus assay

Background: Critical macromolecules of cells such as DNA are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. Selenium and vitamin-E are natural compounds that have been shown to be a direct free radical scavenger. The aim of this study was to investigate the radioprotective effect of selenium and vitamin-E separately and sy...

Effect of polyunsaturated fatty acids and vitamin E level of the sow gestation diet on reproductive performance and on level of alpha tocopherol in colostrum, milk and dam and progeny blood serum.

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...

Importance of diet of dam and colostrum to the biological antioxidant status and parenteral iron tolerance of the pig.

Fifteen second-parity sows were used to determine the importance of vitamin E (E) and selenium (Se) supplementation of the sow's diet and colostrum consumption by the neonatal pig on tolerance to parenteral iron. Selenium (.1 ppm) and E (50 IU/kg) supplementation of the diet of the sow increased plasma tocopherol and Se concentrations, but did not increase plasma glutathione peroxidase (GSH-Px)...
