[Comparison of the effectiveness of oil and water solutions of alpha-tocopherol as radiation protection agent].

Abstract

The change in alpha-tocopherol content (as an index of the antioxidative organism system mobilization) in the brain, liver, muscles and heart of rats prior to and after total gamma-irradiation with lethal dose has been studied. Prior to the irradiation alpha-tocopheryl-acetate (oil solution), alpha-tocopheryl-phosphate dipotassium salt (water solution), gammaphos (prepared WR 2721, water solution) were introduced into rats. It is shown that water-soluble form of vitamin E is more effective than gammaphos and much more efficient than oil form of alpha-tocopherol.
