title: [Course of non-specific bronchial reactivity to histamine after bronchospasm induced by allergen challenge in patients with bronchial asthma].
abstract: Bronchial hyperresponsiveness is the characteristic feature of bronchial asthma. Inhalation of allergen can cause dual asthmatic response--early and late reaction. Thirteen patients with mild and moderate asthma underwent bronchial allergen challenge. Non-specific bronchial reactivity was measured before, 90 minutes, on the 2nd, 7th, 14th day after provocation. Peak Expiratory Flow was measured every hour during 12 hours after challenge to search for late phase reaction. Increased bronchial reactivity was discovered as early as 90 minutes after challenge, it was still observed on the 2nd and 7th but not on the 14th day after allergen provocation. No relationship was found between appearance of late asthmatic reaction and increased bronchial reactivity.
