Chronic Bronchitis

The definition of chronic bronchitis requires that productive cough be present on most days for a minimum of three months in the year in at least two consecutive years in order to make the diagnosis. The disease is probably the most common debilitating respiratory disease in China. There is a strong association with inhalation of irritant substance such as various forms of air pollution and heavy smokers.

The pathologic findings include hyperplasia and hypertrophy of the submucosal bronchial mucous glands, hyperplasia of bronchiolar goblet cells, sequamous metaplasia of bronchial mucosal cells, chronic and acute inflammatory infiltrates in the bronchial submucosa, profuse inflammatory exudates in the lumens of brochi and bronchiolesand denudation of bronchial mucosa.

In traditional Chinese medicine, this disorder is called "Ke Sou" and is thoughtto be caused by damp, cold and heat phlegm and deficiency of the lungs.
