978例小儿头发微量元素测量分析报告

Analysis of 978 Cases of the Trace Elements of Children Hairs

目的：通过对978例小儿头发微量元素测量分析，了解微量元素的缺乏与小儿临床表现的关系，从而指导对小儿营养性疾病的诊断及治疗．方法：用不锈钢手术剪紧贴头皮取样，长发取距发根3cm内头发．每份取标本发样0．58．采用CTV－202型原子吸收光谱仪火焰测定发锌、铁、钙值．结果：978例中查出缺锌847例（86．6％），缺钙409例（41．8％），缺铁134例（13．7％），通过补充锌、铁、钙制剂，患儿临床症状及体征明显减轻．结论：微量元素的缺乏会引起儿童出现一系列临床症状，如厌食，发育迟缓，易感冒等．头发微量元素的测定简便易行、无痛苦，对小儿营养性疾病的诊断及治疗有一定指导意义．

Objective: To investigate the correlation between lack of the trace elements of children hairsand malnutrition. Methods: Levels of zine, iron, calcium were measured by CTV-202 atomic absorptionphotometer from 978 cases of children hairs. Results: The lack of the trace elememe of children hairswas zince 86.6% (844/978), calcium 41.8% (409/978), iron 13.7% (134/978), respectively, Conclusion:We recommend that the trace elements of children hairs be measurd when children had anorexia,bradygenesis and common cold.
