This study was conducted to investigate of hepatoprotective effect of dandelion water extract (DWE) according to repeated administration of thioacetamide (TAA) induced hepatotoxicity in Spraque-Dawley rats. Thirty rats were randomly assigned to 5 groups; normal control, DWE-control, TAA-control (TAA injection during the feeding of normal diet), TAA&DWE600 (TAA repeated injection during the feeding of DWE 600 mg/kg BW), TAA&DWE1200 (TAA repeated injection during the feeding of DWE 1,200 mg/kg BW). Rats in DWE-control and TAA&DWE groups were treated with DWE (600 or 1,200 mg/kg BW daily) by gavage for 20 days (twice a day). All the rats in the TAA-control and TAA&DWE groups were repeated injection of TAA (100 mg/kg BW) into the abdominal cavity 3 days interval and 12 hrs later, all rats were sacrificed. At the same time, normal control and DWE-control groups were injected normal saline. In TAA&DWE groups, serum alanine and aspartate aminotransferase (ALT, AST) were significantly decreased and triglyceride (TG) synthesis was significantly increased compared to TAA group. As well as total billilubin and GGT were slightly decreased by the treatment of DWE. Lipid peroxidation (MDA) concentration was significantly decreased and hepatic GSH content was slightly or significantly increased in the TAA&DWE groups compared to TAA group. Hepatic antioxidative enzyme activities, such as GSH, GST, SOD and catalase were slightly or significantly elevated by the treatment of DWE. According to these results, When dandelion extract was long term supplied, it could be used as a potential protective material for a longer time liver damage by repeated adminstration of the TAA.
