Objective To investigate relationship between broncho-hyperreactivity (BHR) and pulmonary rehabilitation in patients with active pulmonary tuberculosis. Method Pulmonary function and histamine provocation tests were conducted to compare results in 103 cases. Results Positive rate for histamine provocation test was 13.59％ . Compared with negative group, more patients in positive group developed cough and hemoptysis(P< 0.01).Incidence of BHR in patients with positive result for sputum examination for tubercle bacillus was higher than patients with negative results(P<0.01).Percentage of midexpiratory rate of flow(PMMF)in group with positive provocation test was strikingly lower than that in negative group. Conclusion BHR is closely related to stenosis of little airway in patients with pulmonary tuberculosis. Increased BHR affects pulmonary rehabilitation.
