据报道,胃癌组织中锌含量较正常胃组织含量增高,因而胃癌患者的胃液,其锌含量也较正常人或非胃癌患者的胃液高。利用胃液锌含量的这一差别,可以作为胃癌的鉴别诊断。目前国内已有一些单位开展胃液二硫腙锌定性试验作为诊断胃癌的方法。但还未见有关于胃液锌定量分析的报告。我们用极谱分析法在这一方面作了一些初步工作,现将结果报告于后。
According to reports, the content of zinc in gastric cancer tissues is higher than that in normal gastric tissues, and thus the gastric juice in patients with gastric cancer has higher zinc content than those in normal or non-gastric patients. Using this difference in the zinc content of gastric juice can be used as a differential diagnosis of gastric cancer. At present, some units in China have carried out qualitative tests for dithizone in gastric juice as a method for diagnosing gastric cancer. However, there has been no report on the quantitative analysis of zinc in gastric juice. We have done some preliminary work in this area with polarographic analysis and report the results later.
