摘要
采用PerkinElmerZeeman／3030石墨炉原子吸收分光光度法测定肺癌（56例）、结核（30例）、肺部感染（25例）、健康对照（118例）血清铜、锌含量。结果表明，肺癌组血清钢升高，血清锌降低，铜／锌比值升高；肺结核组血清铜升高，血清锌正常，铜／铸比值高于肺部感染组，低于肺癌组；肺部感染组血清铜、锌、铜／锌比值均无变化。认为铜／锌比值界限划分以肺癌组铜／锌比值＞1．5，肺部感组铜／锌比值＜1．2．结核组铜／锌比值介于1．2～1．5之间为宜。
Serum copper and zinc concentrations were measured with a Perkin Elmer Zeeman/3 030 atomic absorption in56 lung cancer patients, 30 pulmonary tuberculosis patients, 25 pulmonary infection patients, and 118 healthy subjects. The lung cancer group had elevated serum copper concentrations, lower serum zinc concentrations, and elevated Cu/Zn ratios. The pulmonary tuberculosis group had elevated serum copper concentrations, normal serum zincconcentrations, and Cu/Zn ratios that were higher than the pulmonary infection group and lower than the lung cancer group. In the pulmonary infection group, no changes were observed in the serum copper and zinc concentrations.The results indicate that the serum Cu/Zn ratio can be useful in diagnosing lung cancer, pulmonary tuberculosis andpulmonary infection. The standard serum Cu/Zn ratio was found to be more than 1. 5 in lung cancer patients, lessthan 1. 2 in Pulmonary infection patients,and between 1. 2 and 1. 5 in pulmonary tuberculosis patients.
