Abstract
The present author found five patients with attack of allergic diseases caused by working in the tea-garden. To determine causative allergen, an intracutaneous reaction test, provocation test, Prausnitz-Kustner reaction test were carried out on these cases. As a result, these cases were considered to be caused by the inhalation of tea-leaf ciliae scattered in the air, and reasoned that other ciliae of leaves could be inhalative allergens.
Soon after this study had done, the author found many respiratory symptoms among cultivator of chrysathemum. By some allergological tests, these symptoms were also considered to be caused by the inhalation of chrysanthemum-leaf ciliae.
In this article, the author reviewed on these inhalative allergy of ciliae of leaves and respiratory impairments due to agricultural work.
