Vit E有抗氧化作用,能阻止不饱和脂肪酸的过氧化反应,对保护含不饱和脂肪酸较多的细胞膜的完整和功能起到重要作用,评价Vit E营养水平的方法是测定它的血浆浓度,正常的水平在5.0～20.0μg/ml间,通常认为小于5μg/ml时,提示营养不良,可以发生水肿,网状细胞增生,大细胞溶血性贫血。①芬兰对15,089名健康妇女随访8年,证实血清Vit E水平与癌症发生率呈负相关,血清VitE≤7.9μg/ml的妇女有较高的上皮癌症发病率(与激素有关的妇女科癌
Vit E has an antioxidant effect that stops the peroxidation of unsaturated fatty acids and plays an important role in protecting the integrity and function of the cell membrane containing more unsaturated fatty acids. The method for assessing Vit E nutrition level is to measure its plasma concentration, The normal level of 5.0 ~ 20.0μg / ml, usually considered less than 5μg / ml, suggesting malnutrition, edema, reticulocyte proliferation, large cell hemolytic anemia. (1) A total of 15,089 healthy women in Finland were followed up for 8 years, confirming that serum Vit E level was negatively correlated with the incidence of cancer and that women with serum VitE≤7.9 μg / ml had a higher incidence of epithelial cancer (women with hormone-related cancers
