CD45RO CD20及总IgE在声带息肉组织中表达的研究

目的 :从免疫病理学角度探讨细胞免疫、体液免疫和局部变态反应在声带息肉发病中的作用。方法 :对 30例声带息肉组织 (息肉组 )和 10例正常声带组织 (对照组 )采用免疫组织化学方法观察两组CD4 5RO、CD2 0及IgE的表达情况并检测其阳性细胞数。 结果 :息肉组CD4 5RO、CD2 0和IgE阳性细胞数显著高于对照组 (P <0 .0 1) ;声带息肉组织中CD4 5RO、CD2 0和IgE的表达之间无相关性 ;男、女患者间的表达差异亦无统计学意义 (P >0 .0 5 )。 结论 :由T淋巴细胞介导的细胞免疫和B淋巴细胞介导的体液免疫在声带息肉中免疫应答活跃 ;声带黏膜局部变态反应参与了声带息肉的发病 ;在声带息肉的发病机制中免疫病理改变起着重要的作用。

Roles of CD45RO,CD20 and local IgE in the pathogenesis of vocal fold polyps

OBJECTIVE: To investigate the roles of CD45RO, CD20 and local IgE in the pathogenesis of vocal fold polyps. METHOD: Thirty cases of vocal fold polyps and ten cases of normal vocal folds were used in present study by immunohistochemical method to detect the CD45RO, CD20 and IgE cells. A mean numbers of positive cells per high power field(X 400) were counted. All data were analyzed with t-test and correl-test by SPSS10.0 software. RESULT: The number of CD45RO+ cells, CD20+ cells and local IgE cells in vocal fold polyps was significantly more than in normal vocal folds (P < 0.01). The expression of CD45RO+ cells, CD20+ cells and local IgE+ cells in vocal fold polyps was no connection relations. The expression of CD45RO+ cells, CD20+ cells and local IgE cells between male and female vocal fold polyps was no significant(P > 0.05). CONCLUSION: There were active cellular immunity and humoral immunity in vocal fold polyps. Local allergy may play a role in the pathogenesis of vocal fold polyps.
