我们测定了36例食管癌组织中微量元素 Cu、Zn、Mn、Cd。这些元素都是与 SOD 相关的微量元素。结果:癌组织中 Zn、Mn 含量减少,癌组织中 Zn 含量明显低于非癌组织(P<0.001)。而癌组织中 Cu 含量增高,Cu/Zn 比值增大,其 Cu/Zn 比值明显大于非癌组织(P<0.05)。
We measured the trace elements Cu, Zn, Mn and Cd in 36 cases of esophageal cancer. These elements are trace elements associated with SOD. Results: The contents of Zn and Mn in the cancerous tissues decreased, while the contents of Zn in the cancerous tissues were significantly lower than those in the non-cancerous tissues (P <0.001). However, the Cu content in cancerous tissues increased and the Cu / Zn ratio increased, and the Cu / Zn ratio was significantly higher than that in non-cancerous tissues (P <0.05).
