PG - 399-401 AB - OBJECTIVE: To study the expression of transforming growth factor alpha, beta 1 in hyperplastic tissue after endoscopic polypectomy and the effect of corticosteroid. METHOD: Forty patients with nasal polyps were divided into two groups randomly: corticosteroid group (n = 20) with topical application of Budesonide (BUD, 400 micrograms/d) after endoscopic polypectomy and control group (n = 20) without corticosteroid after surgery. The hyperplastic tissues in operative cavity obtained in the 1st and 8th weeks after operation were studied with HE staining and immunohistochemistry technique respectively. RESULT: Morphological changes of hyperplastic tissue after endoscopic polypectomy included pseudostratified epithelium, highly edematous lamina proper and inflammatory cells infiltration, in which the main infiltrative cells were eosinophils (67.5%). Transforming growth factor alpha(TGF alpha) protein was highly expressed in epithelial cells, grand cells and inflammatory cells in the hyperplastic tissue. Transforming growth factor beta 1 (TGF beta 1) protein was highly expressed in inflammatory cells in the hyperplastic tissue. The expression of TGF alpha and beta 1 was significantly decreased after topical BUD spray (P < 0.01, 0.05). CONCLUSION: Transforming growth factor alpha and beta 1 may play an important role in the formation and recurrence of nasal polyps.
