为了早期查明慢性支气管炎(慢支)的阻塞性,观察慢支150例,年龄18～60岁,均有急性呼吸系疾病既往史。分3组,每组50例。第1组年龄34～60岁,临床确诊阻塞性慢支,病程10～25年。第2组临床诊断支气管阻塞有一定困难。第3组年龄18～42岁,临床确诊非阻塞性慢支,病程2～5年。对照组13例,无呼吸系疾病。各组治疗前、后均进行菊粉吸入试验,评定(菊粉)咳出时间;检查纤毛上皮纤毛振动频率;测定排出痰的重量。用O.B.P公式计算纤毛上皮纤毛活
In order to early identify chronic bronchitis (chronic bronchitis) obstruction, the observation of 150 cases of chronic bronchitis, aged 18 to 60 years old, have a history of acute respiratory disease. Divided into 3 groups, each group of 50 cases. The first group of 34 to 60 years old, clinical diagnosis of obstructive chronic bronchitis, duration of 10 to 25 years. Group 2 clinical diagnosis of bronchial obstruction has some difficulties. Group 3 age 18 to 42 years old, clinically diagnosed non-obstructive chronic bronchitis, duration of 2 to 5 years. The control group of 13 cases, no respiratory disease. Before and after treatment were inulin inulin test, assessment (inulin) cough time; check the ciliary epithelial cilia vibration frequency; measured sputum weight. Use O.B.P formula to calculate ciliary epithelial cilia live
