Abstract
Purpose: Pulmonary fibrosis is a potentially lethal inflammatory disease and there has been no effective medication for this progressive disease up to now. As a model, different therapeutic approaches have been applied for paraquat-induced pulmonary injury and fibrosis. Atorvastatin besides cholesterol-lowering effects possesses anti-inflammatory and anti-oxidant properties. The current study was designed to investigate the preventive anti-fibrotic effects of atorvastatin on paraquat-induced pulmonary fibrosis in rats. Methods: The rats were randomly divided into five experimental groups. Group I, control group (saline), group II received a single oral dose of 20 mg/kg paraquat with no treatment and III, IV and V groups received atorvastatin at the doses of 10, 20, and 40 mg/kg/day orally one week before and three weeks after paraquat administration, respectively. The rats were sacrificed 21 days after paraquat. Lung hydroxyproline and serum levels of malondialdehyde (MDA) were determined and lung indices and semi-quantitative histopathological changes were evaluated. Results: Paraquat could significantly increase the serum MDA and lung hydroxyproline levels. Elevated content of tissue hydroxyproline and serum levels of malondialdehyde induced by paraquat, attenuated by atorvastatin at the doses of 10, 20 and 40 mg/kg. Furthermore, histopathological findings and the amount of lung indices showed the beneficial preventive role of atorvastatin in rat pulmonary fibrosis induced by paraquat. Conclusion: In conclusion, the present data show that atorvastatin alleviate the toxic effects of paraquat under the experimental circumstances and may be a useful agent in cases who are in contact or poisoned with paraquat.
