ABSTRACT
OBJECTIVE@#To detect the expression and distribution of the lung surfactant protein D (surfactant protein D,SP-D ) and IL-16 in nasal mucosa of allergic rhinitis and nasal polyps, and then probe into their significance in the pathology of allergic rhinitis and nasal polyps.@*METHOD@#Fifteen cases of allergic rhinitis, fifteen cases of nasal polyps and fifteen cases of inferior turbinate mucosa were studied to detect the expression of SP-D and IL-16 by immunohistochemistry method.@*RESULT@#The expression of SP-D and IL-16 in allergic rhinitis and nasal polyps were dramatically higher in controls (P 0.05).@*CONCLUSION@#Both normal tissue and diseased tissue express SP-D and IL-16. SP-D is likely to play key roles in the inflammatory reaction process of allergic rhinitis and nasal polyps. IL-16 is an important eosinophil chemokine in the process of allergic rhinitis and nasal polyps,and it can also enhance the local role of eosinophils,thus it can involve in the process of allergic rhinitis and nasal polyps disease.
