[Content of ubiquinone and ubichromenol in rat liver at various levels of vitamin E saturation of the body].

The content of these substances in the albino rat liver with vitamin E-deficiency is shown to decrease by 16 and 23%, respectively. The intravenous administration of alpha-tocopherol to the vitamin E-deficiency rats causes a gradual 45% increase in the ubiquinone content 4h after which remains at the same level for 8 h; the ubichromenol content 2 h latter is 1.7 times as high and then it lowers gradually up to the level in the avitaminous animals.
