Article Abstract

Objective: To investigate the effect and mechanism of Gualou Xiebai (GLXB) decoction on pulmonary fibrosis.

Method: Pulmonary fibrosis was induced by bleomycin A5 in SD rats. Rats in treatment group were killed after being treated by GLXB by decoction daily for 28 days. The lungs of all rats were harvested for histopathological studies. The contents of platelet-derived growth factor BB (PDGF-BB) in lungs were measured and compared.

Result: The contents of PDGF-BB in lungs have increased significantly in model group compared with normal group and treatment group (P<0.05).

Conclusion: GLXB decoction could significantly alleviate the increased PDGF-BB expression in lungs of pulmonary fibrosis rats.

Gualou Xiebai Decoction (GLXB) is a classic prescription of Chinese medicine used for the treatment of cardiac problems. The present study was designed to explore the effect and mechanism of GLXB on ischemia/reperfusion (I/R) induced disorders in myocardial structure and function, focusing on the regulation of energy metabolism and the RhoA/ROCK pathway. After hyperlipidemic rat model was established by oral administration of high fat diet, the rats were treated with GLXB for 6 weeks and subjected to 30 min occlusion of the left anterior descending coronary artery (LADCA) followed by 90 min reperfusion to elicit I/R challenge.
