ABSTRACT
AIM@#In a previous study, the anti-inflammatory effects of tectorigenin were disclosed. In this study, the anti-inflammatory effects of tectorigenin on acute lung injury using a lipopolysaccharide (LPS)-induced acute lung injury (ALI) mouse model were investigated@*METHOD@#The cell-count in the bronchoalveolar lavage fluid (BALF) was measured. The animal lung edema degree was evaluated by the wet/dry weight (W/D) ratio. The superoxidase dismutase (SOD) activity and myeloperoxidase (MPO) activity was assayed using SOD and MPO kits, respectively. The levels of inflammatory mediators, including tumor necrosis factor-α (TNF-α), IL-1β, and IL-6 were assayed using an enzyme-linked immunosorbent assay method. Pathological changes of lung tissues were observed through HE staining. The inflammatory signal pathway related protein nuclear factor NF-κB p65 mRNA expression was measured by real-time PCR, and the protein level of NF-κB p65 was measured using Western blotting analysis.@*RESULTS@#The data showed that treatment with the tectorigenin markedly attenuated the inflammatory cell numbers in the BALF, decreased nuclear factor NF-κB p65 mRNA level and protein level in the lungs, and improved SOD activity and inhibited MPO activity. Histological studies showed that tectorigenin substantially inhibited LPS-induced neutrophils in lung tissue compared with the model group.@*CONCLUSION@#The results indicated that tectorigenin had a protective effect on LPS-induced ALI in mice.
