摘要
用原子吸收分光光度法测定了50例食管癌患者和16例正常人食管组织中微量元素铜、锌、铁、钴、锰、镍的含量。结果:①食管癌组织铜含量明显高于癌旁组织、余差异无显著性;②正常人食管组织锰、钴高于食管癌组织及癌旁组织,铜低于癌组织,但与癌旁组织差异无显著性。作者认为.食管癌组织铜含量升高可能是癌变的结果。食管癌病人食管组织锰、钴低于正常人有可能是癌变原因之一。
Copper zinc, manganese, cobalt,iron and nickel in the esophageal tissues obtain-ed from 50 patients with esophageal cancer and 16 normal subjects (died in accidents)were measured with atomic absorption spectroscopy. the results showed that: (1)the amount of Cu in the esophageal cancerous tissues was statistically higher thanthat in the corresponding normal tissues (adjacent to cancer) (2) Mn cnd Co in thepatients, esophageal tissues (the cancerous and the corresponding normal tissues)were lower than those in the normal subjects. The Cu level in the tissues of thenormal subjects was lower than that in the cancerous tissues, but the level was notsignificant differenct from that in the corresponding normal tissues. In our study, itis considered that the increase of Cu level in the cancerous tissues is probably theconsequece of tumour: and the decrease of Co as well as Mn in the patients' tissuesmay be one of the causes of esophageal cancer.
