  • Vitamin E, selenium and tri-o-cresylphosphate interrelationships

    Creator:
    Shull, Lee R.
    Abstract:
    A two-part study was conducted to investigate some of the nutritional relationships between dietary tri-o-cresylphosphate (TOCP), a toxic stress material, and dietary vitamin E and selenium. In part one, growth rate of male weanling Long-Evans rats and day-old Japanese quail (Coturnix coturnix japonica) was used to determine the protective action...

  • 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...
