目的 观察 SOD在 Hp感染与胃癌、胃粘膜不典型增生及慢性胃炎之间所起的作用。方法 采用免疫组织化学方法观察 SOD在 Hp感染阳性胃癌、胃粘膜不典型增生及慢性胃炎组织中的表达。结果 Hp感染的阳性胃癌、胃粘膜不典型增生及慢性胃炎组织中的 SOD表达无变化。而在胃癌、胃粘膜不典型增生及慢性胃炎三者之间 SOD的表达有差异。结论 胃癌、胃粘膜不典型增生及慢性胃炎组织中 SOD的表达不受 Hp感染的影响。监测胃粘膜中 SOD的变化 ,可为早期诊断胃癌提供帮助
Objective To observe the role of SOD in Hp infection and gastric cancer, gastric dysplasia and chronic gastritis. Methods Immunohistochemistry was used to observe the expression of SOD in Hp-positive gastric cancer, gastric dysplasia and chronic gastritis tissues. Results There was no change in SOD expression in Hp-positive gastric cancer, gastric dysplasia, and chronic gastritis tissues. There were differences in the expression of SOD between gastric cancer, gastric dysplasia and chronic gastritis. Conclusion The expression of SOD in gastric cancer, gastric dysplasia and chronic gastritis tissues is not affected by Hp infection. Monitoring SOD Changes in Gastric Mucosa Can Provide Assistance for Early Diagnosis of Gastric Cancer
