In Japan, Japanese cedar (Cryptometria japonica) and cypress
(Chamaecyparis obtusa) pollens are considered to be the major
unique allergens which can give rise to severe pollinosis and their
extent of dispersal is quite wide, especially in the urban area.
Cry j 1 is a causative substance of Japanese cedar pollinosis, and
it may deteriorate by Cry j 1 invasion to a lower respiratory
tract. We observed airborne particles containing Cry j 1 by an
immunofluorescence technique using a fluorescence microscope. We
evaluated a Cry j 1 reacted with various air pollutants by liquid
phase reaction. My study will pay attention to pollen morphological
observation, allergenic measurement of airborne pollens and
cross-antigenicity evaluation in Japanese urban areas, also
including the investigation of various pollens in Chinese urban
areas. Morphological changes of pollens will be observed by an
optical microscope, a fluorescence microscope and a scanning
electron microscope to confirm the existing evidences of visualized
suspended particulate matter containing the Japanese cedar and
cypress pollen allergens.
