食管癌组织中铜、锌、锰、镉的测定

Determination of Trace Elements Containing in the Tissues of Esophageal Cancer

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)。

In 36 cases of esophageal cancer,determination was made of the quantities of the trace elements of Cu,Zn,Mn,Cd,which are related to SOD.The results showed that the levels of Zn and Mn containing in cancer tissues were lower than those containing in non-cancer tissues There was very significant difference in the level of Zn between cancer tissues and non-cancer tissues (P<0.001).The Cu content in cancer tissues increased;the Cu/Zn ratio was higher in cancer tissues than in non-cancer tissues (P<0.05).
