Objective: To investigate the role of adhesion molecule ICAM-1 (Intercellular adhesion molecule-1) in eosinophilia and prognosis of nasal polyps.
Method: Expression of ICAM-1 were detected and quantified in 35 cases of nasal polyps with fluorescence-immunohistochemistry analysis and its relationships to eosinophilia and prognosis of nasal polyps were evaluated.
Result: The numbers of eosinophils in nasal polyps and control nasal mucosas were 28.4 +/- 10.7/mm2 and 9.9 +/- 8.6/mm2, and fluorescent densities of ICAM-1 were 115.9 +/- 82.4 and 28.2 +/- 17.1. The expression of ICAM-1 was associated with the heaviness of nasal polyps.
Conclusion: ICAM-1 may play an important role in the formation and prognosis of nasal polyps.
