Abstract
Pneumonia is a common infectious disease with high morbidity and mortality. It is caused by a variety of pathogenic microorganisms that infect the lung parenchyma. Anti-infective drugs are one of the preferred choices for the treatment of pneumonia. Pachymic acid (PA) is a lanolin triterpene compound from Poria cocos, which has antiemetic, anti-inflammatory, and anticancer properties. Although PA inhibits inflammatory response in a variety of diseases, its role in pneumonia is not clear. In this study, we established that PA improved histopathological changes in the lungs of rats with pneumonia. PA inhibited the expression of inflammatory cytokines in the serum of rats having pneumonia. In addition, PA inhibited the apoptosis of cells from rat lung tissues. Mechanically, PA inhibited inflammation and cell apoptosis via NF-κB and MAPK pathways. Therefore, PA could serve as a promising drug for treating pneumonia.
