Abstract Title:
Formononetin inhibited the inflammation of LPS-induced acute lung injury in mice associated with induction of PPAR gamma expression.
Abstract:
Formononetin has shown a variety of pharmacologic properties including anti-inflammatory effect. In the present study, we analyzed the role of formononetin in acute lung injury induced by lipopolysaccharide (LPS) in mice. The cell counting in the bronchoalveolar lavage fluid (BALF) was measured. The animal lung edema degree was evaluated by wet/dry weight ratio. The superoxidase dismutase (SOD) activity and myeloperoxidase (MPO) activity was assayed by SOD and MPO kits, respectively. The levels of inflammatory mediators, tumor necrosis factor-α (TNF-α) and IL-6,were assayed by enzyme-linked immunosorbent assay method. Pathological changes of hung tissues were observed by HE staining. Peroxisome proliferator-activated receptor (PPAR)-γ gene expression was measured by real-time PCR. The data showed that treatment with the formononetin group markedly attenuated inflammatory cell numbers in the BALF, increased PPAR-γ gene expression and improved SOD activity and inhibited MPO activity. The histological changes of the lungs were also significantly improved by formononetin compared to LPS group. The results indicated that formononetin has a protective effect on LPS-induced acute lung injury in mice.
