本研究主要利用流式细胞术DNA／Ki67双标记法同时检测恶性实体肿瘤细胞的DNA含量、细胞周期和Ki67的表达和周期分布，并探索其相互之间和与病理组织学分级的关系。1材料与方法1．1材料1999年2～8月，经我院病理确诊的新鲜恶性实体瘤标本87例。按病理组织学分级，高分化肿瘤9例?
In this study, flow cytometry DNA/Ki67 dual-labeling method was used to detect the DNA content, cell cycle and Ki67 expression and cycle distribution of malignant solid tumor cells at the same time, and to explore their relationship with each other and pathological histological grade. 1Materials and methods 1.1 Materials From February to August 1999, 87 cases of fresh malignant solid tumors were diagnosed by pathology in our hospital. According to histopathological grade, 9 cases of well-differentiated tumors?
