title: [Expression of inducible nitric oxide synthase in allergic fungal rhinosinusitis].
abstract: OBJECTIVE
  To investigate the expression of inducible nitric oxide synthase(iNOS) in the mucus involved in allergic fungal rhinosinusitis(AFRS) and chronic sinusitis(CRS).
  
  
  METHODS
  The iNOS expression was examined using immunohistochemistry in cases of AFRS as well as CRS.
  
  
  RESULTS
  The expression rate of iNOS in AFRS was significantly higher than in CRS.
  
  
  CONCLUSIONS
  The increased expression of iNOS may involve in AFRS pathogenesis. Statistical difference between AFRS and CRS groups may indicate two groups may be distinct diseases entity.
