Abstract:

OBJECTIVE: To observe the effects of cistanche phenylethanoid glycosides(CPhGs) on TGF-β1 expression of rats with hepatic fibrosis induced by bovine serum albumin(BSA). METHODS: Seventy-five SD rats were randomly divided into six groups:Normal(distilled water-treated),model(BSA-treated),positive drug(BSA-treated+ compound Biejia Ruangan tablets(BJRG,600 mg/kg),and BSA-treated+CPhGs(125,250,500 mg/kg) groups. BSAtreated+CPhGs(125,250,500 mg/kg) groups consisted of 13 rats in each group,and other various group had 12 rats in each group. Using intravenously injected BSA-induced rat liver fibrosis model,rats were fed with different therapeutic drugs for 12 weeks. After the experiment serum and liver tissues of rats were collected. Measurements of serum enzymes,liver fibrosis markers,serum TGF-β1 concentration,Masson staining to show the histopathological changes and the expression of TGF-β1 were recorded. RESULTS: Compared with model group,except for ALB and the low dose group TB and DB,various dose CPhGs groups(125,250,and 500 mg/kg) could significantly lower liver enzymes in serum(P<0.05),liver fibrosis markers(P<0.05),and TGF-β1 content(P<0.01). Moreover,Masson staining showed BSA-treated+CPhGs(125,250,500 mg/kg) groups could alleviate the degree of liver fibrosis,which was significantly lower than the model group(P<0.01). The expression of TGF-β1 protein in liver tissue of different dose groups were also inhibited significantly(P<0.05 or P<0.01). CONCLUSION: CPhGs demonstrated protective effects on hepatic fibrosis induced by BSA in rats,and one of mechanisms maybe the inhibited expression of TGF-β1 in hepatic fibrosis tissue.
