title: Increase of lipid hydroperoxides in tissues of vitamin E-deficient rats.
abstract: The level of lipid hydroperoxides was determined by a newly developed method in rat tissues of vitamin E deficiency, which was a good in vivo model of enhanced radical reactions. In the heart, lung and kidney, the level of lipid hydroperoxides increased significantly as early as 4 weeks after feeding on a tocopherol-deficient diet compared with that of the control group. After 8 weeks of the deficiency, similar results were obtained. These results indicate that the lipid hydroperoxide is available as an extremely sensitive indicator of lipid peroxidation in these organs, because it takes several months to detect manifestations of the vitamin deficiency based on conventional indices.
