本文采用多种上皮性标记物的免疫组织化学技术,对非肿瘤性鼻咽上皮的抗原表达特性进行研究。结果表明鼻咽部所有上皮均表达角蛋白,但性质不同的上皮所表达的分子量不同。采用商品化癌胚抗原多克隆抗血清可能存在非特异性反应,至于上皮膜抗原则见于鼻咽部所有上皮成分。对上皮性标记物在鼻咽部组织表达的规律及意义作了探讨。 In this paper, the immunohistochemical technique of a variety of epithelial markers was used to study the antigen expression characteristics of non-tumorous nasopharyngeal epithelium. The results showed that all epithelia of the nasopharynx express keratin, but the molecular weight expressed by epithelial cells with different properties is different. Polyclonal antisera against commercially available CEA may have nonspecific responses, and epithelial membrane antigens are found in all epithelial components of the nasopharynx. The regularity and significance of epithelial markers in nasopharyngeal tissue were discussed.
