107例高龄老人头发锰铜锌铬微量元素含量的探讨

Study on Content of Trace Elements (Mn, Cu, Zn,Cr)in Hair of 107 Advanced Age Persons

对１０７例７０～８０岁高龄老人作头发８种微量元素含量测定，测定结果以Ｍｎ，Ｃｕ，Ｚｎ，Ｃｒ与长寿地区广西巴马县老人作比较，结果表明本组是低Ｍｎ、高Ｃｕ、低Ｚｎ、高Ｃｒ，差异极为显著（Ｐ＜０．００１），符合非长寿地区低Ｍｎ的现状．本组与４５～５９岁，６０～６９岁二个年龄组比较，本组为高Ｍｎ、低Ｃｕ、低Ｚｎ、高Ｃｒ，差异均显著（Ｐ＜０．０５），表明本组微量元素组合优于７０岁前老人．从本组男、女微量元素比较，女性表现为高Ｍｎ、高Ｓｒ、高Ｃａ、低Ｃｒ、低Ｃｕ，说明老年女性在抗衰防衰方面优于老年男性．

The content of trace elements in hair of 107 cases of 70￣80 years old persons was detected.The content of Mn,Cu,Zn and Cr of 8 trace elements in hair of 107 cases was compared with that of advanced age persons in Bama county where people have long life in Guanxi,The cases examined in this study had lower content of Mn and Zn and higher content of Cu and Cr.There was significant difference between two groups (P<0.001).which cornforms to present situation of lower content of Mn in hair of advanced age personsin non-longlife area.The subject group was also compared with two age groups of 45￣59 years old and 60￣69 years old. The results showed that the subject group's content of the trace elements was higher in Mn and Cr and lower in Cu and Zn, and the differences were both significant(P<0.05).The results indicated that the subject group's combination of the trace elements was better than that of elderly people under the age of 70 years old.The content of men's and women's trace elements in hair of the subject group was compared with each other.The results showed that the women's content of trace elements was higher in Mn, Sr and Ca and lowed in Cr and Cu. which indicate that aged women were better than aged men in ageing preventing and ressisting.
