Vitamin E (tocopherol) concentrations in blood plasma were determined in 48 infants and correlated with their nutritional status. Infants were divided into two groups as following: group I (n : 12) estimated well-nourished, and group II (n : 36) appreciated undernourished. Clinical nutritional status was evaluated according to their weight, height and skinfold thickness of triceps percentiles. Plasma vitamin E levels were analysed by a modification of the spectrophotometric micro-technique of Fabiank et al. (using 0.2 ml of plasma). There was difference in serum tocopherol levels between two groups: 1.21 (0.21) mg/dl: mean (+/- SEM) in group I in front of 1.84 (0.18) mg/dl in group II (0.10 greater than p greater than 0.05). On the other hand, vitamin E concentrations were correlated with the skinfold thickness of triceps percentiles by a logarithm curve: y = 2.25-0.31 1n X (r: 0.35, p less than 0.02). Probably, serum vitamin E levels do not reflect the tissue store status in undernourished infants without malabsorption.
测定了48名婴儿血浆中的维生素E（生育酚）浓度，并将其与他们的营养状况相关联。婴儿被分为以下两组：第一组（n = 12）估计营养良好，第二组（n = 36）被认为营养不良。根据他们的体重、身高和三头肌皮褶厚度百分位数评估临床营养状况。血浆维生素E水平通过对法比安克等人的分光光度微量技术进行改进来分析（使用0.2毫升血浆）。两组之间的血清生育酚水平存在差异：第一组为1.21（0.21）毫克/分升：平均值（±标准误），而第二组为1.84（0.18）毫克/分升（0.10＞p＞0.05）。另一方面，维生素E浓度与三头肌皮褶厚度百分位数通过对数曲线相关：y = 2.25 - 0.31 ln X（r：0.35，p＜0.02）。可能，血清维生素E水平不能反映无吸收不良的营养不良婴儿的组织储存状况。
