A Clinical Study of Japanese Cedar (Cryptomeria japonica) Pollen-Induced Asthma
acethylcholine bronchial provocation test Japanese cedar non-specific airway hypersensitivity pollen-induced asthma
2010/11/17
Background: Grass and birch pollens are known to induce asthma. However there are few reports about other pollen-induced asthma. Japanese cedar is the most common allergen in rhinitis in Japan but is ...
Forecasting Models for Sugi (Cryptomeria japonica D. Don) Pollen Count Showing an Alternate Dispersal Rhythm
annual pollen count dispersal rhythm forecasting model periodicity sugi (Cryptomeria japonica)
2010/11/17
An alternate pollen dispersal rhythm represented by a dummy variable in the multiple regression analysis plays a key role in improving forecasting models for the total annual sugi pollen count.
Preseasonal scattering of Cryptomeria japonica pollen in Japan, with reference to the dormancy of the male flowers
Cryptomeria japonica dormancy male flower pollen emission prediction
2010/11/26
Pollinosis caused by Cryptomeria japonica is a very serious health problem in Japan. To clarify the relationship between C. japonica pollen emissions before the main pollen dispersal season and dorman...

2010/11/24
Background: A number of recent studies have clarified the characteristics of major allergens of Cryptomeria japonica, such as the locality, molecular weights of Cry j 1 and Cry j 2 and cross-reactivit...
The formation of pollen in male flowers and yearly atmospheric pollen counts of Cryptomeria japonica in the following year
atmospheric pollen Cryptomeria japonica male flower production pollinosis
2010/11/29
Prediction of yearly atmospheric pollen counts is a very important component in the prevention of allergenic symptoms. We investigated the relationship between atomspheric pollen counts and the format...
