TI  - Plantago lanceolata (English plantain) pollinosis in Japan.
PG  - 251-6
AB  - OBJECTIVE: The objective was to ascertain the prevalence of Plantago lanceolata 
      (English plantain) pollinosis in Japan. METHODS: A total of 160 patients with 
      allergic rhinitis were examined at the Hokkaido University Hospital 
      Otolaryngology Clinic between January 2002 and December 2003. We investigated the 
      frequency of P. lanceolata antigen-specific immunoglobulin E (IgE) 
      antibody-positive serum using the radioallergosorbent test (RAST), the P. 
      lanceolata pollen counts in the Sapporo area and the clinical symptoms of 
      patients with allergic rhinitis caused by this pollen. RESULTS: P. lanceolata 
      pollen was dispersed throughout the Sapporo area from mid-May to early September, 
      peaking in the latter half of May. The airborne pollen count showed little 
      variation between years. The P. lanceolata RAST-positive rate was 12.8%, which 
      was close to those for ragweed and sagebrush. All subjects showed overlapping 
      antigen sensitization, that is, none displayed sensitization (by RAST) 
      exclusively to P. lanceolata. The onset of subjective symptoms peaked in June and 
      the symptoms worsened from April to October. CONCLUSION: P. lanceolata was 
      dispersed over a long period, from mid-May to early September. The P. lanceolata 
      RAST-positive rate (12.8%) was similar to those for sagebrush and ragweed, which 
      are dispersed during the fall. These results suggest that P. lanceolata is an 
      important causative agent of pollinosis in Japan.
