在幽门螺杆菌(H·pylori)相关胃病中,研究肠上皮化生其细胞增殖动力学改变,对胃癌发生机制的研究比较重要。为此我们应用免疫组化和组化方法对伴有肠上皮化生的胃黏膜细胞增殖核抗原PCNA、Ki- 6 7表达进行分析。1 材料和方法1.1 研究对象 所选病例均系1997～2 0 0 0年门诊和
In Helicobacter pylori related gastropathy, the study of intestinal metaplasia changes in cell proliferation kinetics, the study of the mechanism of gastric cancer is more important. To this end, we used immunohistochemistry and histochemistry to analyze the expression of proliferating cell nuclear antigen PCNA, Ki- 67 in patients with intestinal metaplasia. 1 Materials and Methods 1.1 Selected subjects were selected from 1997 to 2000 out-patient and
