title: [Bronchial response to allergens after controlled NO2 exposure (author's transl)].
abstract: The bronchial response to inhaled grass pollen (assessed by specific airway resistance, SRaw, measurements) was determined in seven allergic patients after each had spent 1 hour in an exposure chamber breathing on one occasion unpolluted air and on a separate occasion (one week interval) a mixture of air and nitrogen dioxide (NO2, 207 micrograms/m3). Sequences of exposure to unpolluted air and to NO2 were randomized in a single-blind fashion. No significant change in baseline SRaw or in the response to antigen was observed after NO2 exposure.
