To observe the effects of systemic steroids on the infiltration of eosinophils and the expression of TGF beta 1 in nasal polyps.
The SP immunohistochemical methods were applied to explore the expression of TGF beta 1 in nasal polyps before and after corticosteroids use; the optical density of positive cells in mucosal epithelia, eosinophils, glandular epithelium, vascular endothelial, matrix and mucous membrane was measured by using HPIAS-1,000 image-conduct system.
The expression of TGF beta 1 was positive in nasal polyps. The number of eosinophils and the expression of TGF beta 1 was significantly reduced in nasal polyps after treated with corticosteroids compared with pre-treated.
The effects of systemical steroid use on the nasal polyps may depend on decreasing the infiltration of eosinophils and the expression of TGF beta 1.
