[LONG-TERM RESULTS OF AIRBORNE POLLEN SURVEYS IN THE JAPANESE ARCHIPELAGO FROM THE PERSPECTIVE OF POLLEN ANTIGEN].

Background: In 1986, the Ministry of Health and Welfare started an airborne pollen survey as part of measures against JC pollinosis. We reported the important tree pollen antigens in 2016. We have now estimated the longitudinal investigated results for successful prevention and treatment for allergic symptoms related to grass and weed pollen in Japan.

[LONGITUDINAL MONITORING OF TREE AIRBORNE POLLEN IN JAPAN].

Rational: In Japan patients with Japanese Cedar (JC) pollinosis have increased nation widely since the latter of 1970's. The Ministry of Health and Welfare of Japanese Governments has begun to take preventive measures against JC pollinosis and airborne pollen monitoring has begun to investigate as a causative agent since 1986. We have estimated the longitudinal investigation result for successful prevention and treatment against pollinosis in Japan.

Relationship between the visiting birds and nectar secretion in the cherry tree.

The flying birds to cherry tree, Prunus campanulata, are well known. However since their relationship has not yet been examined, then the present study elucidated their relationship at Tama Forestry and Forest Product Research Institute. The observation of flying birds was carried out on their species, number, attitude and visiting time, with naked eye, a video camera, and a camera from the blind.
