3、Abstract〕 Objective To discuss the effects of Qingfei Huatan decoction combined with erythromycinin COPD (chronic obstructive pulmonary disease) model rats, including IL-8 in serum、BALF and airwayinflammation. Methods 40 SPF level Wistar rats were ran
4、domly divided into 4 groups, COPD modelrats were induced by complex factors, which is in order to observe the effects of Qingfei Huatan decoctioncombined with erythromycin on the expression of IL-8 in serum、BALF and airway inflammation. Results Compared wi
5、th control group, model group appeared cell injury in small airway, inflammatory wallcells infiltration, angiogenesis and integration of alveoli, IL-8 levels in serum and BALF increased significantly;compared with those of model group, after the intervention, s
6、mall airway tissue injury, wall infiltration ofinflammatory cells, angiogenesis and integration of alveoli were all improved, IL-8 levels in serum and BALFdecreased significantly in erythromycin group; compared with those of erythromycin group, indices of eryth
7、romycin+ Qingfei Huatan decoction group were decreased significantly. Conclusion Qingfei Huatan decoctioncombined erythromycin can reduce the expression of IL-8 in serum and BALF, significantly inhibit the change of airway inflammation, suggesting Qingfei
