Abstract
Context: Ampelopsis brevipedunculata Maxim (Vitaceae) is a traditional medicinal herb used for treating liver disorders.
Objective: The hepatoprotective effects of A. brevipedunculata ethanol extract (ABE) was investigated in experimental models of fibrosis.
Materials and methods: Hepatic stellate cells (HSCs) system in vitro and thioacetamide (TAA)-induced liver fibrosis rat model in vivo were used. Sprague–Dawley rats were divided into five groups of eight each (control, TAA, TAA with ABE 10 mg/kg, ABE 100 mg/kg and silymarin 50 mg/kg groups, respectively). Fibrosis was induced except to the control group by TAA (200 mg/kg, i.p.) twice per week for 13 weeks. ABE and silymarin was administered orally six times per week from the 7th week to the 13th week.
Results: In HSC-T6 cells, ABE (0.1 mg/mL) and silymarin (0.05 mg/mL) significantly (p < 0.01) induced apoptosis (12.94 ± 5.72% and 14.9 ± 3.8%, respectively) compared with control group (7.51 ± 1.26%). The expression of fibrosis related genes (TGF-β, α-SMA and Col1A1) in HSC-T6 cells were significantly (p < 0.01) downregulated in ABE-treated groups compared with control group. In in vivo studies, ABE (10 and 100 mg/kg) treatment ameliorated the altered levels of serum biomarkers significantly (p < 0.01 and p < 0.001) in TAA-induced groups. Further, ABE (10 and 100 mg/kg) significantly (p < 0.01) attenuated the altered histopathological findings, glutathione content and the accumulation of hydroxyproline.
Conclusion: These results collectively indicate that ABE can potentially be developed as a therapeutic agent in the treatment of hepatic fibrosis.
