title: [Study on the relationship between nitric oxide and allergic rhinitis].
abstract: OBJECTIVE
  To investigate the relationship between nitric oxide (NO) and allergic rhinitis (AR).
  
  
  METHODS
  NO in the serum of 50 patients with AR and 40 healty control were measured by nitrate reductase.
  
  
  RESULTS
  The level of serum NO in AR group was higher than that in healthy control group (P < 0.001).
  
  
  CONCLUSIONS
  There is a relationship between the level of NO in serum and AR. The results suggest that the NO may play an important role in the pathogenesis of AR.
