title: Late and delayed responses of the nasal mucosa to allergen challenge.
abstract: In 600 patients suffering from allergic rhinitis the possible existence of another type of allergic reaction of the nasal mucosa other than Type I (immediate) was investigated by means of nasal provocation tests with allergens. Late response of the nasal mucosa to allergen challenge indicated that Type III hypersensitivity might be involved. Delayed reactions also made Type IV suspect.
