To investigate the relationship between immune status of adenoids and secretory otitis media (SOM).The adenoid tissue samples of 72 cases with SOM and 30 cases with adenoid hypertrophy without SOM were studied by immunohistochemical method.The PCNA, BCL-2, CD4+, CD8+ and CD4+ / CD8+ in SOM tissue samples were 30.85 +/- 1.73, 21.27 +/- 1.25, 41.90 +/- 9.07, 20.45 +/- 7.08 and 2.10 +/- 0.17, respectively, which were much more than that of tissue samples without SOM (25.25 +/- 1.75, 14.05 +/- 1.02, 16.30 +/- 8.21, 11.15 +/- 5.71, 1.39 +/- 0.15 respectively) (P0.01). The expression of CD4+ in T-lymphocyte was obviously higher than that of CD8+.In adenoid tissues of SOM patients, the activity of T-lymphocyte subsets are increased,the adenoids are enlarged and local immunity are enhanced. Therefore,adenoidectomy should be applied in SOM patients as early as possible. |
