In this study we evaluated protective and therapeutic effects of Flaxeeed Oil (FO) on Bleomycin (BLM) lung fibrosis in rats.Methods: 30 males wistar rats were randomly divided into 3 equal groups: untreated group (G1) and 2 treated groups (FO, 1g/kg bw/day). G2 received FO during two months before inducing lung fibrosis than G3 received FO 2 days after inducing lung fibrosis during 10 days. Pulmonary fibrosis was induced by BLM (4 mg/kg, intratracheally single dose). Inflammatory index, fibrosis score (Ashcroft) and TGF-β density was evaluated in different areas of damaged lung by anatomo-histological and immuno-histological analysis.Results: Independent-samplesTtest revealed that comparatively to control group (G1). FO reduced significantly fibrosis score in G2 and TGF-β density in fibrocytes in G3 (p<0,05).Figure 1. Distribution of TGF-β in fibrocytes of treated groups (G2, G3) and control group (G1).Figure 2. Score of fibrosis of treated groups (G2, G3) and control group (G1).Conclusion: These data demonstrated a protective activity of FO against bleomycin-induced lung fibrosis model in rats.More investigations will be realized in human to prove relationship between diet and interstitial lung diseases.
