摘要
采用日立 1 80 - 3 0型原子吸收 /火焰分光光度计 ,对 3 6例食管癌组织中微量元素 Zn、Mn的含量进行了测定 ,并与食管癌患者的癌旁正常食管组织和正常人的食管组织进行了对照比较。结果表明 :食管癌组织中 Zn、Mn含量显著低于癌旁食管组织和正常人食管组织中 Zn、Mn的含量 ,分化差程度的食管组织中 Zn、Mn的含量显著降低。提示微量元素 Zn。
The contents of Zinc(Zn) and Manganese(Mn)in cancerous from 36 patients with esophageal cancer were measured with atomic absorption spectrophotometry,which was compared with normal esophageal tissues in patients with esophageal cancer and normal persons'.The results show that the contents of Zn and Mn in cancerous tissues are lower than in the patients'normal esophageal tissues and that in the normal subjects,the contents of Zn and Mn in cancerous tissues with worse histologic grading are even lower.The results indicate that there in close relationship between trace element and esophageal cancer.
