Red blood cell tocopherol and liver tocopherol in hyperlipemic rats as compared with plasma tocopherol

Lipids, 1985
AbstractIn rats with hyperlipemia induced by Triton WR‐1339, changes in tocopherol concentrations in plasma and RBC were compared with those in the liver and its subcellular fractions, microsomes and mitochondria.After daily injection with Triton, plssma total lipids at 3 days and 7 days, respectively, showed elevation 6.5 times and 15 times as high as

η-Tocopherol (7-Methyltocol) : a New Tocopherol in Rice

Nature, 1956
RECENT publications have confirmed the existence of two previously unknown natural tocopherols in the lipid fractions of cereal grains (ɛ- and ζ-tocopherols) and have described methods for their separation by paper chromatography1–3. Thus six of the seven possible tocol structures produced by methylation of the tocopherol chroman nucleus have been ...

The Effect of α-Tocopherol on the Nitration of γ-Tocopherol by Peroxynitrite

Archives of Biochemistry and Biophysics, 1999
It has been proposed (S. Christen et al. Proc. Natl. Acad. Sci. USA 94, 3217-3222, 1997) that although alpha-tocopherol (alpha-TH) is an efficient antioxidant, the presence of gamma-tocopherol (gamma-TH) may be required to scavenge peroxynitrite-derived reactive nitrogen species.

ALPHA-TOCOPHEROL AND ALPHA-TOCOPHEROL PHOSPHATE IN THE PROPHYLAXIS OF THROMBOEMBOLISM

Archives of Surgery, 1953
IN THE first seven months of 1949, thromboembolic disease developed postoperatively in nine patients in the surgical service of the Snyder-Jones Clinic, Winfield, Kan., and two of these nine patients died with pulmonary embolism. During the summer of 1949, we learned of the work later reported by Ochsner, DeBakey, and DeCamp, and by Kay and his co ...

Tocopherol Deficiency in Man

New England Journal of Medicine, 1965
THE pathophysiologic effects of vitamin E deficiency in man remain uncertain some forty years after isolation and purification of this vitamin. Although tocopherol depletion in infants and children with steatorrhea is well documented, no clear-cut clinical syndrome secondary to tocopherol deficiency is recognized.1 , 2 Certain in vitro phenomena of ...

Tocopherol Therapy in Acanthocytosis

Pediatrics, 1971
Acanthocytosis or a-beta-lipoproteinemia is a rare inborn error of metabolism known also as the "Bassen Kornzweig syndrome."1 We had See Images in the PDF File the opportunity to examine a Jewish girl, H.F., 11 years old, with a-beta-lipoproteinemia. The girl has healthy parents of Turkish origin who are first cousins, and

Ubiquinone and Tocopherol in Birds

Nature, 1961
UNLIKE the rat and the rabbit, it seems from nutritional studies made by several groups of workers that the chicken needs little vitamin E, providing its diet contains an adequate supply of selenium and only limited amounts of unsaturated fat1–3. Since tissue-levels of ubiquinone in the rat4 and rabbit5 are high compared with those given for some other

New insights into tocopherol research with emphasis on gamma-tocopherol and delta-tocopherol

2006
Vitamin E research in recent years has broadened and changed, with a shift from studies using only synthetic -tocopherol towards the evaluation of other forms, mainly - and -tocopherol. In addition, alternative functions of vitamin E have been proposed, in particular the effects of - and -tocopherol on gene expression. These non-antioxidant functions ¿

Chromatographic separation of tocopherols

Journal of Chromatography A, 2001
alpha-, beta-, gamma-, and delta-Tocopherols were separated by reversed-phase high-performance thin-layer chromatography (C18RP-HPTLC), normal-phase high-performance liquid chromatography (NP-HPLC), reversed-phase high-performance liquid chromatography (C18RP-HPLC), and gas chromatography (GC). The selected topological indices based on connectivity (M,

A reassessment of tocopherol chemistry

Biochemical and Biophysical Research Communications, 1964
Abstract This paper describes the presence in Nature of four methylated tocols (the 8-monomethyl, 5,8- and 7,8-dimethyl and 5,7,8-trimethyl derivatives) and the four related tocotrienols (for nomenclature see Bunyan, McHale, Green and Marcinkiewicz, 1961 ).
