【摘要】 为了进一步探讨口腔扁平苔藓（ＯＬＰ）与幽门螺旋杆菌（ＨＰ）的关系，本研究应用非放射性ＤＩＧ系统的原位杂交技术对２０例ＨＰ－ＰＣＲ阳性的ＯＬＰ患者作ＨＰ－ＤＮＡ的检测。结果显示：在２０例ＯＬＰ的损害组织中，１８例为ＨＰ－ＤＮＡ阳性，２例为阴性，而对照组均为阴性。结果提示ＯＬＰ损害组织中ＨＰ所致的病理变化可能是某些ＯＬＰ的发病基础。更多还原

【Abstract】 In order to discuss the relationship of oral lichen planus(OLP) and helicobacter pylori(HP),in situ hybridization was applied to detect HP DNA in the lesions of 20 OLP cases who were HP PCR positive. The result showed that 18 of 20 OLP cases had positiveness of HP DNA and 2 negativeness. It is indicated that HP in the lesions of OLP may result in pathological change which may be the pathogenic basis of OLP.更多还原
