Core Tip

Core tip: Cholestasis often fails to respond to medical therapy, resulting in liver necrosis, fibrosis, cirrhosis and subsequent liver failure. Bicyclol has significant liver protective effects but little is known about the effect of this drug on cholestatic liver fibrosis. Therefore, the present study was designed to investigate the protective effects of bicyclol in a rat model of liver fibrosis induced by bile duct ligation (BDL). Bicyclol can improve liver function after BDL and decrease bile duct proliferation, inflammation and fibrosis. Bicyclol might be an effective anti-fibrotic drug for the treatment of cholestatic liver disease.
