ABSTRACT
Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by progressive and irreversible fibroblasts proliferation leading to significant respiratory insufficiency. This study was designed to investigate the effect of sage infusion against bleomycin (BLM)-induced lung fibrosis in rats. Male Wistar rats were given a single dose of BLM (4 mg/kg, intratracheal), while sage infusion (50, 100 and 150 mg/kg, intraperitoneal) was administered 3 day later and continued for 4 weeks. We reveled by HPLC and LC-MS methods an important amount of phenolic bioactive compounds such as vanillic, gallic, ellagic, rosmarinic and carnosic acids. BLM induced collagen deposition, increased lipid peroxidation (MDA) and decreased superoxide dismutase (SOD) and catalase (CAT) activities. Only sage infusion at 150 mg/kg normalized MDA and antioxidant enzyme levels (SOD and CAT) and reduced significantly lung fibrosis. Our results showed also that this high dose have no renal or hepatic cytotoxic effect. In conclusion, sage can protect against BLM-induced murine lung fibrosis and oxidative stress due to the large content of bioactive phenolic compounds.
