Cheng等人(1981)研究了女性腺癌患者淋巴细胞核仁形成区(NOR)的银染多态性,发现患者G组染色体NOR Ag-阳性率显著高于正常人,而提出癌细胞可能产生特殊物质激活个体的NOR.本文作者对一些卵巢癌和乳腺癌患者的端着丝粒染色体NOR的变异进行了研究.方法:用常规全血培养获得染色体标本,患者为45名37～87岁妇女(卵巢癌19人,乳腺癌25人,兼患两种癌1人).卵巢
Cheng et al. (1981) studied the silver-staining polymorphism of lymphocyte nucleolaris formation (NOR) in female patients with adenocarcinoma and found that the positive rate of NOR Ag-positive chromosome in group G was significantly higher than that of normal people, suggesting that cancer cells may have special Substance-activated Individuals NOR The authors examined the alterations of the telocentric NOR in some patients with ovarian and breast cancer.Methods: Chromosome specimens were obtained from routine whole blood cultures in 45 women aged 37-87 years ( 19 ovarian cancer patients, 25 breast cancer patients and 1 patient with both cancers.)
