[摘要]目的 检测诱导型一氧化氮合酶(iNOS)、5-羟色胺(5-HT)在病理性瘢痕及正常皮肤组织中的表达,探讨其与病理性瘢痕增生及痛痒的关系。方法 应用免疫组化技术对痛痒、非痛痒的病理性瘢痕和正常皮肤组织中iNOS、5-HT的表达及分布情况进行检测,并采用图像分析法对检测结果进行半定量分析。结果 痛痒的瘢痕组织与正常皮肤组织相比,iNOS、5-HT的表达均显著升高( F=25.47、44.92,q=4.39、4.43,P <0.01);非痛痒的瘢痕组织与正常皮肤组织相比,iNOS表达显著升高( q=3.96, P <0.01),5-HT表达差异无显著性( q=2.64,P >0.05);痛痒的瘢痕组织与非痛痒的瘢痕组织相比,5-HT的表达显著升高( q=3.92,P <0.01),iNOS的表达差异无显著性( q=2.71,P >0.05)。结论 iNOS 可能与病理性瘢痕的形成有关,其增高可能促进瘢痕的增生;5-HT可能与病理性瘢痕的临床痛痒症状有关,其增高可能导致病理性瘢痕临床痛痒症状的发生。[关键词] 一氧化氮合酶;血清素;瘢痕

[ABSTRACT]ObjectiveTo study the expressions of inducible nitric oxide synthase (iNOS) and 5-hydroxytryptamine (5-HT) in abnormal scar and normal skin and their relationship with the scar proliferation and itching or pain. Methods Immuno-histochemical method was adopted to detect iNOS and 5-HT in itching or painful scars and non-itching or non-painful scars and nor-mal skin tissues ......
