I.緒言
鼻アレルギーの診断と治療において特異抗原の検索は最も事症要な因子のひとつである。特異抗原の険索には,各種の皮膚反応,Prausnitz-Ktlstner反応1),鼻粘膜言誘発反応などが一般的である。最近ではradioallcrgosorbellt test(以下RASTと略す)がin vitroの検出法として注目されつつある。しかし,問診や鼻鏡所見から鼻アレルギーが強く疑われるにもかかわらず,これら既存のアレルギー検査では抗原の検出されない症例も存在する。これらの症例に対して,われわれは,鼻粘膜組織のradioallergosorberit testを施行し,抗原の検出を検討した。
In order to find out specific antigens from the patients with nasal allergy, various methods have been designed, and radioallergosorbent test (RAST), as a in vitro method, is possible to detect IgE antibodies. In some cases, however, specific antigens can not be detected by any tests. We designed a new method for detection of IgE antibodies from the patients, and IgE antibodies which are not revealed by any previous examinations are detected in nasal mucosa by RAST. We named this new method "t-RAST". In this paper, we discussed about the type of nasal allergy with special pathology―localized type of nasal allergy―, and the possibility that IgE antibodies might be produced in the nasal mucosa.
