Glutathione peroxidase and selenium distribution in semen and reproductive tissues of farm animals

Creator:: Alabi, Nathaniel Sigismund
Abstract:: This study was conducted to investigate the distribution of glutathione peroxidase (GSH-Px) and selenium in semen of the boar, bull, ram and stallion, and in the reproductive tissues of the boar, bull and ram. The effect of repeated noncryoprotective freeze-thawing on GSH-Px activity was also studied. Both hydrogen peroxide (H₂0₂)...

Interaction of selenium with cadmium and mercury in semen and reproductive tissues: in vivo and in vitro studies

Creator:: Alabi, Nathaniel Sigismund
Abstract:: Studies were conducted to investigate the metabolism of selenium (Se) , and the influences of Se on the metabolism of cadmium (Cd) and inorganic mercury (Hg) in rats, and in ram semen in vitro. Se-deficient (-Se) or Se-adequate (+Se) rats were injected intraperitoneally with either ¹⁰⁹CdCl₂ (5 μCi/rat) or ²⁰³HgN0₃...

A metabolic function of selenium, assessed with rat liver homogenates

Creator:: Bull, Richard Charles
Abstract:: In three separate trials rats were fed either a basal diet deficient in selenium and vitamin E or the same diet supplemented with one or both of these factors. In addition to these treatments in two of the trials, ethoxyquin was included to provide adequate lipid antioxidant protection and to...

Influence of dietary selenium on the distribution of tritium-labeled vitamin E in the rate

Creator:: Cheeke, Peter R.
Abstract:: A series of four trials were conducted to determine the influence of selenium supplementation of a selenium- and vitamin E-deficient basal diet on the absorption, excretion, tissue distribution and placental transfer of a single dose of tritium-labeled α-tocopherol in the rat. In the first trial, the effect of supplementation of...

The effect of selenium on chemical carcinogenicity in the rat

Creator:: Johnston, Weldon Kearney
Abstract:: One hundred and fifty-one weanling rats of both sexes were fed control diets or diets containing 160 ppm diethylnitrosamine (DEN) or 150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was calculated so that the LD₅₀ should be achieved at about 17 weeks. Each carcinogen treatment was incorporated with three different diet...

Selenium effects and species differences in hepatic metabolism of pyrrolizidine alkaloids and other xenobiotics

Creator:: Shull, Lee R.
Abstract:: The metabolism of pyrrolizidine alkaloids and other drugs was studied with regard to nutritional status and species differences. Pyrrolizidine alkaloids which are biotransformed to severely toxic metabolites were isolated from tansy ragwort (Senecio jacobaea). Semi-purified alkaloid crystals containing five alkaloids (senecionine, seneciophylline, jacobine, jacoline, and jacozine) were prepared and found...

Effects of selenium and glutathione peroxidase on the biosynthesis of prostaglandin E₂ and F₂α by the ram vesicular gland

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: This study was conducted to investigate the involvement of selenium and glutathione peroxidase in prostaglandin biosynthesis by the ram vesicular gland. Vesicular glands were collected from healthy intact rams covering a wide range of selenium nutrition and were analyzed for selenium concentrations, glutathione peroxidase activities and levels of prostaglandin E₂...

Nutritional interrelationship of cobalt and selenium in lambs and weanling rats

Creator:: Wise, William Robert, Jr.
Abstract:: The purpose of this thesis is to determine if dietary and metabolic relationships exist between cobalt and selenium. Two groups of lambs were compared. The dams of one group of lambs received an alfalfa hay adequate in selenium and the dams of the other group received an alfalfa hay deficient...

Selenium deficiency in the equine

Creator:: Basler, Susan E.
Abstract:: Whole blood selenium levels were measured in 207 horses, representing 41 ranches and 11 regions throughout Oregon. Age, sex, diet, and history of disease were recorded. Diet was divided into three categories; local feed only, commercial feed, and Se supplemented feed. Region (p<.01), diet type (p<.01), and a region x...
