Abstract:
Objective To observe the effects of Qizhi Zhoufei Granules on IL-8, TNF-αand ET-1 in serum and bronchoalveolar lavage fluid (BALF) of chronic obstructive pulmonary disease (COPD) model rats, and to study its mechanism of preventing and treating COPD. Methods Wistar rats were randomly divided into blank group, model group, positive control group, Qizhi low-dose group, Qizhi medium-dose group and Qizhi high-dose group. The COPD model was established by smoking and infusing lipopolysaccharide (LPS). After 15 days, the rats were given the drugs by orally taking once a day. On the 43rd day, the change of IL-8, TNF-α and ET-1 content in serum and BALF were measured by radio-immunity assay. Results Compared with the blank group, the level of IL-8, TNF-α and ET-1 in serum and BALF were considerably raised in model group (P<0.05). Whereas compared with the model group, the level of TNF-αin serum of Qizhi high-dose group was remarkably lowered (P<0.05), the level of IL-8 in serum of Qizhi low-dose group and Qizhi high-dose group was remarkably lowered (P<0.05), the level of TNF-αin BALF of Qizhi medium-dose group was remarkably lowered (P<0.05), the level of IL-8 in BALF of Qizhi low-, medium- and high-dose group was remarkably lowered (P<0.05), and the level of ET-1 in BALF of Qizhi high-dose group and Qizhi medium-dose group was remarkably lowered (P<0.05). Conclusion Qizhi Zhoufei Granules have protective effect on lung tissue of COPD rats, and can adjust the content of IL-8, TNF-α and ET-1, which may be one of its mechanisms of intervening occurrence and development of COPD.
