近年来,许多专家报道了正常献血员和各种不同肿瘤患者血中微量元素的浓度。其中最常用的检测方法是原子吸收分光光谱测定法。在有转移的何杰金氏病和其它恶性淋巴瘤病人中,往往发现血清铜水平升高.然而,各家研究表明各种癌症病人中血清铜水平并不一致。同样,癌症病人血清锌水平和血清铜锌比例报道亦不一致。有关红细胞中微量元素含量的详细研究较少,迄今,几乎没有关于癌症病人红细胞中铜和锌水平变化的报道,特别是实体瘤.作者用诊断性 X 射线光谱测定法(X 射线荧光光谱分析技术)检测了70例正常献血员和138例各种不同实体瘤(乳腺癌77例、前列腺癌13例、结肠癌13例、肺癌7例、恶性黑色素瘤5例、及其它肿瘤23
In recent years, many experts have reported the concentration of trace elements in the blood of normal blood donors and various tumor patients. The most commonly used detection method is atomic absorption spectrometry. In patients with metastatic Hodgkin’s disease and other malignant lymphomas, serum copper levels are often found to increase. However, studies have shown that serum copper levels are not consistent in various cancer patients. Similarly, reports of serum zinc levels and serum copper to zinc ratios in cancer patients are also inconsistent. There are few detailed studies on the content of trace elements in red blood cells. To date, there have been few reports of changes in the levels of copper and zinc in red blood cells of cancer patients, especially solid tumors. The authors used diagnostic X-ray spectrometry (X-ray fluorescence spectrometry). ) 70 normal blood donors and 138 different solid tumors were examined (77 breast cancers, 13 prostate cancers, 13 colon cancers, 7 lung cancers, 5 malignant melanomas, and 23 other cancers)
