[Use of the antioxidant complex of vitamins A, E and C in murine leukemia].

A study was made of the content of ubiquinone, vitamins A, E, ascorbic, dehydroascorbic and diketogulonic acids (DKGA), and malonic dialdehyde (MDA) in the liver, of the content of glutathione, the activity of superoxide dismutase (SOD) and glutathione reductase in red blood cells, of the content of vitamins A, E and ubiquinone in the spleen of C57Bl/6jG mice with inoculated leukemia La. It was found that in red blood cells of the animals with leukemia, the content of vitamin E and DKGA reduced, the MDA level increased, and the content of glutathione dropped whereas SOD activity rose. Application of the antioxidant complex of vitamins A, E, C appreciably improved the characteristics of enzymatic and non-enzymatic antioxidant protection of the liver and red blood cells of the leukemic animals without exerting any noticeable effect on the content of vitamin E and ubiquinone in the leukemic spleen tissue.
