头发是“记录”微量元素在体内蓄积量的生物材料,取材方便易行,且为无损伤的检查。许多研究表明,硒是人和动物的生命必需微量元素,在预防疾病,促进健康与长寿等方面有着重要的作用。本文通过16例服用抗衰中药“活力苏”(该药系由成都中医学院研制)六个月的老人发硒与15例未服药正常老人发硒进行测定对比,以探讨服药后发硒含量的变化,为抗衰老作用的研究提供参改。本实验所分析的样品均经过严格的前处理,采用2,3—二氨基荼荧光法在日本岛津(SHIMADZU)R—510荧光分光光度计上进行服药与对照组的发硒样品的含量测定,结果如下: 1.关于含硒量的标准:根据一些资料介绍,国外发硒含量范围为0.64—2.35PPm,X=1.88PPm;国内发硒含量范围为0.155— Hair is a biological material that “records” the accumulation of trace elements in the body. It is easy to obtain and is free from damage. Many studies have shown that selenium is an essential trace element for humans and animals, and plays an important role in preventing diseases and promoting health and longevity. In this article, 16 selenium samples were taken from 16 elderly patients taking the anti-aging Chinese herbal medicine “vigorous Su” (developed by Chengdu University of Traditional Chinese Medicine) for the first time in six months and selenium in 15 untreated normal old people to determine the selenium content after taking the medicine. Changes, providing changes to the study of anti-aging effects. The samples analyzed in this experiment were subjected to rigorous pre-treatment. The selenium samples were measured by the 2,3-diaminofluorene fluorescence method on a Shimadzu R-510 fluorescence spectrophotometer in Japan and control groups. The results are as follows: 1. Regarding the standard of selenium content: According to some data, the selenium content in foreign countries is 0.64-2.35PPm, X=1.88PPm; the domestic selenium content is 0.155-
