本文应用荧光分光光度法,测定了24例肺癌和8例良性肺病变的病变组织和病变旁组织硒水平。结果癌组织硒水平显著高于癌旁组织硒。指出肺癌患者血清硒和恶性胸液硒水平降低的主要原因与癌组织富积硒有关。
In this paper, fluorescence spectrophotometry was used to determine the selenium levels in the tissues and adjacent tissues of 24 lung cancers and 8 benign lung lesions. Results The selenium level in cancer tissue was significantly higher than that in the adjacent tissue. It was pointed out that the main reason for the decrease of serum selenium and malignant pleural fluid selenium levels in lung cancer patients was related to the accumulation of selenium in cancer tissues.
