牧区牧民老年人头发中微量元素含量的调查研究

INVESTIGATION OF THE CONTENT OF TRACE ELEMENTS IN THE OLD HERDSMANS HAIR IN THE PASTORAL AREA

本文调查了内蒙古牧区牧民老年人和城市老年人150名头发中的微量元素(Zn、Cu、Fe、Co、Ni、Mn、Cr、Mo、V、Se、Al)的含量,并对它们与人体健康、疾病、衰老等方面进行了研究。研究结果表明,Fe、Co、Ni、Cr、Mo、V、Se、Al等元素城市居民普遍高于牧民。在牧民中,患心血管疾病、神经系统疾病等比城市居民多,平均寿命也短。这可能与体内缺乏一些人体必需微量元素有关。此结果主要是由于:牧民的膳食结构不合理,摄取营养素不全,营养比例失调。

The paper describes an investigation made among 150 healthy aged people in the pastoral area and the city of Inner Mongolia. The content of trace elements in the hair (Z_n、C_u、F_e、C_o、N_i、Mn, C_r、M_o、V、S_e、Al) and its relation to health, disease, and ageing have been studied. The result has shown that the content of F_e,C_o,N_i,C_r,M_o,V,S_e,Al is generally more in the dwellers' hair in the city group than in the pastoral area group. The herdsmen are easier to suffer from never and heart diseases than the dwellers in the city and the average life expectancy of the herdsman is short, too. This may be due to the shortage of trace elements man needs. The nutrient taken is not enough and too simple.
