[Olive pollinosis in Japan].
Olive (Olea europaes) is the most important allergic tree in the Mediterranean area. That is widely distributed at Syodoshima in Japan. I observed olive pollination period and studied the patients with pollinosis. The patients were examined by skin test, measuring of specific IgE antibody and nasal provocation test with olive pollen extract. Allergic responses to olive pollen were found to be present in 16.3% of pollinosis patients. And cross-reactivity between olive and grass pollen (Dactylis glomerata) was suggested. Other literature reported the cross reactivity between the pollens of the Oleaceae family, containing olive, and grass family. From our study we suppose that Oleaceae pollens cause allergic reaction of Gramineae pollinosis patients in Japan.
