The effect of berberine nanomicelles on hepatic cirrhosis in bile duct-ligated rats

Abstract

Objective (s): The anti-fibrotic effect of chronic berberine (BBR) had demonstrated previously in a rat model of bile duct ligation (BDL). The aim of present study was to investigate hepatoprotective effect of BBR nanomicelles on liver cirrhosis induced by BDL in male rats.<br />Materials and methods: After 21 days of drugs' treatments, the serum and tissue levels of hepatic markers were measured and pathologic evaluations performed.<br />Results: BDL could markedly increase aspartate aminotransferase (AST), alanine aminotransferase (ALT), LDH, and total bilirubin (TBIL) serum levels and tissue tumor necrosis factor-alpha (TNF-α) level along with reductions in tissue levels of key antioxidants glutathione (GSH) and superoxide dismutase (SOD) as well as total protein. On the other hand, silymarin (100 mg/kg, p.o.), BBR (100 mg/kg) and BBR nanomicelles (50 mg/kg, p.o.) markedly decreased AST and ALT while enhanced GSH. In addition, BBR nanomicelles (50 mg/kg, p.o.), silymarin (100 mg/kg, p.o.) and BBR (100 mg/kg, p.o.) groups showed a considerable increase in SOD. BBR nanomicelles (50 mg/kg, po.) significantly lowered TNF-α. In addition, nanoBBR treatment prevented liver cirrhosis in histopathologic analysis.<br />Conclusion: Formulation of BBR may represent a worthy approach to enhance the effect of it in liver injuries.
