title: [evaluation of relationships between foods and pollen antigens in peach oral allergy patients -serous specific IgE levels of peach recombinant Antigen-].
abstract: OBJECTIVE
  Evaluation of the relationships between foods and pollen allergens in oral allergy syndrome (OAS).
  
  
  METHODS
  Serous level of specific IgE against recombinant peach allergens (rPru p 1, rPru p 3 and rPru p 4) in 17 peach OAS patients were examined by Pharmacia CAP RASTsystem.
  
  
  RESULTS
  In 17 pollinosis patients, the number of patients positive to peach, rPru p 1, rPru p 4 and rPru p 3 RAST were 13 (76%), 14 (82%), 6 (35%) and 0 (0%), respectively. The RAST value of rPru p 1 was significantly correlated with that of natural birch pollen extract (r=0.745, p=0.0003), but not with that of mugwort pollen extract. The RAST value of rPru p 4 was significantly correlated with that of mugwort pollen extract (r=0.602, p=0.0092), but not with that of natural birch pollen extract.
  
  
  CONCLUSIONS
  Concerning to peach OAS, the most important cross-reactive antigen is Pru p 1 in birch pollinosis, and is Pru p 4 in mugwort pollinosis.
