[Diagnosis of chronic obstructive bronchitis].

Cough and mucociliary clearances were investigated in patients with chronic obstructive bronchitis, chronic bronchitis, chronic nonobstructive bronchitis by ciliary activity of the ciliated epithelium and cough intensity according to the formulas, using inulin and tussographic techniques of expectoration testing. The findings above were compared to clinical manifestations of bronchitis, x-ray pictures, bronchial mucosa bronchoscopy and cytology, examination of external respiration. The analysis of the data obtained provided the conclusion that early diagnosis of chronic obstructive bronchitis is valid in ciliary activity of the ciliated epithelium equal or surpassing 1 and cough intensity under 35%.
