【摘要】 对云南省大理县29名经临床确诊的3～10岁的克山病患者的头发进行了铜、锌、锰、铁、钼、铬、钴及钙含量的测定。并以年龄及性别相同的大理县正常儿童作为对照。元素测定方法除了钼用极谱法外,其余均用原子吸收光谱法。发样用1％洗净剂清洗,高温灰化。 分析结果显示,克山病患者发中锰、铁、钼含量极其显著地高于正常儿童,而发中锌含量又显著低下。更多还原

【Abstract】 Hair trace element concentrations have been measured in 29 age-and sex-matched groups of children with Keshan disease and normal controls.Hair was collected from children aged 3-10 in Yunnan province. The contents of Cu, Zn, Mn, Fe, Mo, Cr, Co, Ca were determined by atomic absorption spectrophotometry and polarography. Mn, Fe, Mo concentrations are higher in hair samples from patients than from controls. Zn contents are lower in patients. Highly significant differences were observed between the two groups in contents of Mn, Mo, and Zn.更多还原
