Quercetin Treatment Ameliorates Systemic Oxidative Stress in Cirrhotic Rats

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Our aim was to investigate whether the antioxidant quercetin protects against liver injury and ameliorates the systemic oxidative stress in rats with common bile duct ligation. Secondary biliary cirrhosis was induced through 28 days of bile duct obstruction. Animals received quercetin (Q) after 14 days of obstruction.
