1987年4—6月我们在湘西花垣县进行苗族儿童锌营养状况研究。按随机抽样法,采用群体取样方式,在三个地区苗族儿童中取发样送往湖南有色地质防治医院微量元素研究指导中心,采用 Perkin Elemer403型原子吸收分光光度进行发锌含量的测定。分析发锌含量结果,结合临床、形态等指标,评价苗族儿童缺锌程 From April to June 1987, we studied the nutritional status of zinc in Miao children in Huayuan County, western Hunan province. According to the random sampling method, population samples were taken and samples were sent to the Trace Elements Research Center of Hunan Non-Ferrous Geological Prevention and Treatment Hospital from three areas. The PerkinElmer403 atomic absorption spectrophotometry was used to determine the zinc content. Analysis of hair zinc content results, combined with clinical, morphological and other indicators to evaluate the lack of zinc in Miao children
