作者对陕西省长寿区老人血清中微量元素(锰、铜、锌、铁)及钙、镁进行分析。发现陕西省长寿区老人血清中利于健康长寿的锰的含量极显著地高于对照区(P<0.001);人体必需的铜的含量也极显著地高于对照区(P<0.01);与抗衰老关系密切的钙的含量也极显著地高于对照区(P<0.01);男性老人血清中锰、铜、锌、铁及钙、镁的含量与女性老人均无显著差异;61岁～90岁的老人血清中锰、铜、锌、铁及钙、镁的含量随着年龄的增长也均未有显著差异。结果表明陕西省长寿区老人血清中有较优越的化学元素谱。本文对实验结果中与抗衰老有关问题进行了讨论。
The authors analyzed trace elements (manganese, copper, zinc, iron) and calcium and magnesium in serum of elderly people in Changshou District, Shaanxi Province. It was found that the content of manganese which is beneficial to health and longevity in serum of elderly people in Changshou District of Shaanxi Province was significantly higher than that in control area (P <0.001). The copper content in human body was also significantly higher than that in control area (P <0.01) The contents of calcium, magnesium, copper, zinc, iron, calcium and magnesium in serum of males were not significantly different from those of female females. The ages of 61 to 90 The content of manganese, copper, zinc, iron, calcium and magnesium in the serum of old people also did not have significant difference with age. The results show that there is a superior chemical elemental spectrum in the serum of elderly in Changshou District of Shaanxi Province. This article discusses the anti-aging related issues in the experimental results.
