ABSTRACT
The aim of this paper was to investigate the effect of Dilong( geosaurus) on the expressions of fibrotic factors TGF-β1 and α-SMA in bleomycin-induced pulmonary fibrosis mice. The binding ability of Dilong to fibrotic factor TGF-β1 was initially detected by Biacore technology and verified by in vivo pharmacodynamics. A total of 60 SPF C57 mice were randomly divided into 6 groups. Except the blank group( injecting 0. 08 m L·kg-1 sodium chloride in the trachea),the other five groups were given bleomycin( 4 mg·kg-1) to replicate the pulmonary fibrosis model. After 14 days of drug treatment,the expressions of TGF-β1 and α-SMA were detected by Masson staining,immunohistochemistry and RT-PCR. The results of Biacore experiment showed that the extract of Dilong was well bound to TGF-β1 protein in vitro,and the binding value reached 619. 3. Compared with the model group,Masson's results showed that cellulose deposition in high-dose,medium-dose and low-dose Dilong groups decreased to varying degrees. RT-PCR results showed that different doses of Dilong could reduce protein and mRNA expressions of TGF-β1 and α-SMA to a certain extent in a dose-dependent manner. In conclusion,Dilong could delay the process of pulmonary fibrosis by binding to target protein TGF-β1 and inhibiting the expression of α-SMA.
