【摘要】 对不同群体的尿镁同时进行测定与比较有助于更好地了解镁的临床意义。以新试剂聚２－丙烯胺缩－３－（４－甲酰基苯偶氮）－４，５－二羟基－２，７－萘二磺酸作显色剂，藉分光光度法同时测定了健康成年人、儿童肾脏及心脏病患者的尿镁。结果表明，健康人（包括儿童）的尿镁高于各种病人，其中与心脏病患者的差异无统计学意义，而与肾脏病患者却具有显著性统计学差异。提示尿镁浓度在一定程度上可反映肾脏的某些病变。更多还原

【Abstract】 To understand well the clinical significance of urinary magnesium,it is necessary to determine and compare simultaneously the urinary magnesium levels of different groups of people.In the present work,urinary magnesium concentrations in healthy adults,children and patients with kidney or heart diseases have been determined by spectrophotometry using a novel condensed product of polyallylamine and 3-(4-formylphenylazo)-4,5-dihydroxynaphthalene-2,7-disulfonic acid (PA-FPNS)as a highly selective polymeric chromogenic reagent.The results showed that urinary magnesium concentrations of healthy people including children are higher than that of various patients.The difference of urinary magnesium between healthy people and patients with heart diseases has no statistical significance,but that between healthy people and patients with kidney disases does have statistical importance,suggesting that urinary magnesium concentration may reflect to a certain extent some renal lesions.更多还原
