Abstract
BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic and fibrotic lung disease of unknown causes. Given the crucial role of oxidative stress in the progression of IPF, antioxidant therapy may be speculated to be an efficient therapeutic approach. Therefore, the present study aimed to evaluate the protective effects of Crocin as a potent, natural antioxidant against Bleomycin-induced PF in male Wistar rats. METHODS: Forty male Wistar rats were randomly divided into four groups. Group 1 received intratracheal saline on day 7 and oral gavage of saline for 28 days. Group 2 received a single dose of Bleomycin on day 7 and oral gavage of saline for 28 days. Groups 3 received a single dose of Bleomycin on day 7, accompanied with oral administration of Crocin for 28 days. Group 4 orally received Crocin for 28 days. Finally, the lungs were removed for measuring the biochemical and histopathological markers. RESULTS: The results showed that Crocin therapy remarkably decreased TNF-α, MDA and NO levels in the lungs of Bleomycin-exposed rats. Furthermore, a significant increase was seen in lung GSH content, catalase, and GPx activities in the Crocin/Bleomycin-treated group as compared with Bleomycin-treated group. However, Crocin could not markedly change the lung index and SOD activity. Histopathological changes, fibrosis and hydroxyproline content of lungs also significantly decreased by Crocin therapy in the Crocin/Bleomycin-treated group. CONCLUSION: In sum, Crocin therapy could modulate biochemical and histological changes induced by Bleomycin; therefore, it might be considered as an effective therapeutic approach against IPF.
