Expression of PCNA, BCL-2, CD4+, CD8+ in the adenoid tissues from children with secretory otitis media / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To investigate the relationship between immune status of adenoids and secretory otitis media (SOM).@*METHOD@#The adenoid tissue samples of 72 cases with SOM and 30 cases with adenoid hypertrophy without SOM were studied by immunohistochemical method.@*RESULT@#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) (P < 0.01). The expression of CD4+ in T-lymphocyte was obviously higher than that of CD8+.@*CONCLUSION@#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.
