摘要: 目的:研究幽门螺杆菌(HP)与胃腺上皮细胞增生的关系, 方法:经PCR检测和组织病理学观察138例胃粘膜活检标本, 采用SP免疫组化染色观察PCNA表达和Feulgen二染色测定细胞核DNA含量。 结果:细胞核DNA含量在慢性浅表性胃炎(CSG)和慢性萎缩性胃炎(CAG)中, 有HP感染与无HP感染比较, 二倍体和近二倍体细胞减少, 增殖倍体增加。 PCNA表达在CSG和CAG中, 有HP感染与无HP感染比较阳性细胞数和均值增加。 结论:HP感染与胃腺上皮细胞的增生程度有密切关系。Abstract: To study the association between helicobacter pylon(HP) infection and epithelialcell hyperplasia of gastric gland. 138 cases of gastric mucosa from the polymerase chainreaction(PCR) technique and observations of histopathology were performed with PCNAexpression of S-P immuncocy to chemical method and DNA content exanines of Feulgen staining. RESULTS: HP infection and non-HP infection compared with diploid andnear diploid cells reduces and proliferating diploid cell increased, in the chronic superficialgastritis(CSG) and the chronic atrophic gastritis(CAG) on the study of the DNA content of cell nucleus. HP infection and non-HP infection compared with increased of positive cells, in the expression of PCNA with S-P immunohistochemical staining CONCLUSION: The degree of the epithelial cell hyperplas of gastric gland was very correlative to HP infection.
