摘要：Serum vitamin E concentration was analysed in 59 (27 males and 32 females) free-living, healthy, middle-income volunteers with mean age of about 68 years (range, 63-73) from the Nagano City area in Japan. We assessed the vitamin E status of this population using two criteria, i.e., serum vitamin E concentration and the ratio of vitamin E (mg) to triglycerides plus cholesterol (g) in serum. Averages (±SD) of serum vitamin E concentration of the population including both males and females were 0.94±0.26mg/dl in July and 0.98±0.22mg/dl in December. In each season, about 15% of the population had a value of less than 0.7mg/dl and were assessed to be under low or marginal vitamin E status including only one deficient subject (0.46mg/dl) in July according to the first criterion. Averages of the ratio of vitamin E to lipid level (triglycerides plus cholesterol) in serum were 3.06±0.78mg/g in July and 3.15±0.76mg/g in December. In the latter season, the vitamin E status of one subject was assessed to be in inadequate according to the second criterion. In this population, the values of both lipid peroxides and relative fluorescence intensities in serum, and urinary creatine-to-creatinine ratio were normal in the subjects assessed to have low or marginal vitamin E by its concentration in serum. These results suggest that the vitamin E status of this population was acceptable, and that the ratio of vitamin E to lipid level seems to be a more reliable criterion for the assessment of vitamin E status than its serum concentration.
