title: [The effect of antianaphylaxis drugs on specific IgE and eosinophil in serum of patients with allergic rhinitis].
abstract: OBJECTIVE
  To study the roles of leukotriene and histamine in the pathogenesis of allergic rhinitis and to compare the efficacy between leukotriene receptor antagonist and antihistamine by mensurating specific IgE in serum and eosinophil in peripheral blood and nose secretion of patients with allergic rhinitis respectively.
  
  
  METHODS
  The patients were randomly divided into two groups and administrated montelukast sodium and loratadine respectively for two weeks. The specific IgE in serum and eosinophil in peripheral blood and nose secretion smear of patients were detected and then the state was evaluated by patients themselves and doctors.
  
  
  RESULTS
  After treatment the level of specific IgE in serum and eosinophil count in peripheral blood and nose secretion smear of patients were significantly lower than that before treatment (P < 0.05); There were no significant differences in the change of the level of specific IgE in serum and eosinophil count in peripheral blood and nose secretion smear between two groups after treatment (P > 0.05).
  
  
  CONCLUSIONS
  Treating patients with allergic rhinitis with montelukast sodium and loratadine were of similar effect. Histamine and leukotriene are both important inflammatory factors in the pathogenesis of allergic rhinitis and both play roles by affecting eosinophil accumulation and activation and by decreasing the formation of specific IgE. Leukotriene receptor antagonist is a new drug to treat allergic rhinitis.
