近年来,金属元素特别是微量元素与肺癌的关系日益受到重视.不少研究表明,肺癌患者血清中铜、锌、钙、镁均有明显变化.但组织水平研究较少,结果也不一致,迄今国内尚无这方面的报道.本研究通过对四组不同肺组织中铜、锌、钙、镁含量的测定以探讨其与肺癌的关系.1 研究对象 肺癌组:40例.男31例,女9例;年龄40~75岁;平均55.48岁.肺部良性病变组:20例.男12例,女8例;年龄20岁~68岁,平均42.24岁.荷瘤组;20例,男15例,女5例;年龄45~75岁,平均54,95岁;本组标本系取自肺癌同一肺叶内,但离癌灶2.5
In recent years, the relationship between metal elements, especially trace elements, and lung cancer has received increasing attention. Many studies have shown that serum copper, zinc, calcium, and magnesium all have significant changes in patients with lung cancer. However, there are few studies at the organizational level, and the results have been inconsistent. There is no report in this area. This study examined the relationship between copper, zinc, calcium, and magnesium levels in four different lung tissues to explore its relationship with lung cancer.1 Study group Lung cancer group: 40 cases. Male 31 cases, female 9 cases; age 40-75 years old; average 55.48 years old. Benign lung disease group: 20 cases. Male 12 cases, female 8 cases; aged 20 to 68 years, mean 42.24 years. Tumor-bearing group; 20 cases, male 15 Cases, female 5 cases; aged 45 to 75 years old, average 54 and 95 years old; specimens of this group were taken from the same lobe of lung cancer, but from the cancer foci 2.5
