Abstract

The efficacy of pharmacopeial alpha-tocopheryl acetate, alpha-tocopheronolactone and the antioxidant diludin was studied as to the possibilities of preventing E-hypovitaminosis muscle dystrophy in rabbits. alpha-Tocopheronolactone action was similar to that of pharmacopeial alpha-tocopheryl acetate as regards E-vitamin activity that was manifested by an increase in the body mass, decrease in the urine creatine index and maintenance of normal ubiquinone content, as well as of succinate-ubiquinone-reductase, NADH-ubiquinone-reductase and NADH-cytochrome c-reductase activity of rabbit skeletal muscle and heart mitochondria. On the contrary , as a result of the antioxidant administration, no direct correlation was found between ubiquinone content and activity of ubiquinone-dependent enzymatic systems of mitochondria. The data obtained attest to high E-vitamin activity of alpha-tocopheronolactone. The action of the latter was disclosed to be different from that produced by the antioxidant.
