为了解尿毒症患者全血微量元素的变化及长期血液透析对其影响，测定３０例非透析和３６例长期血液透析的尿毒症患者以及４０例健康人的全血锌、铁、钙、铜、锰、镁的含量。结果：非透析的尿毒症患者血锌和铁明显下降（Ｐ＜０．０１），铜、钙、锰、镁无变化，长期血液透析者血锌和铁明显下降（Ｐ＜０．０１），铜、钙、镁升高（Ｐ＜０．０５或Ｐ＜０．０１），锰无变化。认为：尿毒症患者、长期血液透析者全血微量元素有变化，主张对尿毒症患者常规、适量补锌、铁和钙
In order to understand the changes of trace elements in whole blood of patients with uremia and the effect of long-term hemodialysis on them, 30 cases of uremia patients without hemodialysis and 36 cases of chronic hemodialysis and 40 healthy persons were enrolled in the study of zinc, iron, calcium, copper, Manganese, magnesium content. Results: The levels of zinc and iron in serum of non-dialysis patients with uremia were significantly decreased (P <0.01), copper, calcium, manganese and magnesium did not change, blood zinc and iron of long-term hemodialysis patients were significantly decreased (P <0.01) Copper, calcium, magnesium increased (P <0.05 or P <0.01), manganese did not change. That uremia patients, long-term hemodialysis whole blood trace elements have changed, advocated uremic patients routine, appropriate zinc, iron and calcium
