  • Description:
    In response to a large number of patients visiting the hospital with seasonal rhinitis, a study of pollinosis was begun in the rural areas of Japan. Vegetation in these areas was more varied and in greater quantities than in an urban settings. Nagano Prefecture, where the study was conducted, is a tableland in the middle of the main island of Japan. It has a deciduous and broad leaf tree zone. A chronology of airborne pollen was established and an intradermal test was also begun to discover which dusts were allergens among the pollinosis patients at the allergy department of the hospital. Specific immunoglobulin-E antibodies were examined whenever practical. The incidence of allergic rhinitis was high among individuals aged 20 to 40 years. Incidences were concentrated during March through October, with two peaks occurring during this period. Particular problems were associated with Japanese cedar, birch, oak, and walnut trees. Studies are not yet complete of alder, white mulberry and zelcova trees. Orchard grass was the most important allergen in the Gramineae family. The most important allergen of the weeds was common mugwort. Special findings in tests of walnut pollinosis, apple pollinosis, orchard grass pollinosis, short ragweed pollinosis, and common mugwort pollinosis were presented. In the extreme cases, pollinosis becomes an occupational allergy. [Description provided by NIOSH]
