Objectives

Narrative objectives1

To examine induced sputum mucin levels in patients with bronchial asthma or chronic cough by using sputum induction. To examine the relationships between induced sputum mucin levels and various clinical indices in patients with bronchial asthma by using exhaled nitric oxide measurement, pulmonary function, methacholine airway responsiveness and capsaicin cough sensitivity test, questionnaire, etc.
