摘要:   目的 探讨过敏性疾病主要变应原屋尘螨特异性抗原的定位。 方法 选用屋尘螨过敏患者的阳性血清特异性IgE抗体作探针,制作屋尘螨石蜡切片,HE染色后光镜观察其内部形态结构,免疫组织化学染色分析其特异性抗原定位。 结果与结论 内部形态结构,消化系统占据大部分体腔,可见口咽部、前中肠 (胃 )、中肠、后中肠等结构。中肠 (尤其是后中肠)见明显的粪便颗粒,体腔见生殖腺等器官。免疫组织化学染色,见雌、雄屋尘螨的多种组织抗原定位均呈阳性反应,其特异性抗原主要定位于口咽部、中肠组织及肠内容物

Abstract:  Objective To study the localization of specific allergen of Dermatophagoides pteronyssinus. Methods Through optical microscope,the specific allergens of D.pteronyssinus were observed in paraffin sections using D.pteronyssinus specific IgE antibodies from the patient sera. Results and Conclusion The digestive system was found occupying large parts of body cavity of D.pteronyssinus by HE staining, while the specific allergens of D.pteronyssinus were mostly occurred in the midgut tissue, gut contents, cuticle and reproductive system in the immunostained sections. The results also showed that many parts of D. pteronyssinus were recognized by the specific IgE antibodies obtained from allergic individuals to D.pteronyssinus, which provided a theoretic base for further study of isolation and purification of the specific allergen.

Key words: Dermatophagoides pteronyssinus, Allergens, Antigenic localization
