卵巢浆液性癌是妇科常见的恶性肿瘤 ,其发病率高而存活率低 ,不易早期诊断。目前病因不清 ,有关癌细胞膜活性的研究报道甚少。我院 1999年 5月至 2 0 0 0年 1月应用光、电镜酶细胞化学方法在超微结构方面观察了肿瘤细胞膜酶的分布及酶活性变化 ,现报道如下。1　材料与方法1 1　 Serous ovarian cancer is a common gynecological malignancy, the high incidence of the disease and low survival rate, not easy to diagnose early. At present, the cause is unclear, and few reports on the activity of cancer cell membrane have been reported. Our hospital from May 1999 to January 2000 application of light, electron microscopy enzyme cytochemistry in the ultrastructure of the tumor cell membrane enzyme distribution and changes in enzyme activity are reported below. 1 Materials and Methods 1 1
