Abstract
This study was conducted to determine the effect of fermented water extracts from Ligularia fischeri (LAF) on reduction of hepatotoxicity induced by D-galactosamine (D-GalN) in rats. In this experiment, male Sprague- Dawley rats were used as experimental animals, which were divided into eight groups: normal group, D-GalN-treated group (control), D-GalN and non-fermented water extracts from Ligularia fischeri (LA)-treated groups (100, 200, and 400 mg/kg BW (body weight)), and D-GalN and LAF-treated groups (100, 200, and 400 mg/kg BW). γ-Glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase activities in serum of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05). The high density lipoprotein-cholesterol levels of the D-GalN and LAF-treated groups increased significantly compared to those of the control group (P<0.05). The low density lipoprotein-cholesterol and triglyceride levels of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05). The atherogenic index values of the D-GalN and LAF-treated groups decreased significantly compared to those of the control group (P<0.05), and their high density lipoprotein cholesterol by total cholesterol ratio increased significantly in these groups (P<0.05). Superoxide dismutase activity of liver tissues were enhanced significantly (P<0.05) in the D-GalN and LAF-treated groups compared to that of the control group (P<0.05), whereas their malondialdehyde content decreased significantly in these groups (P<0.05). The histopathological observations revealed apoptotic cells and mild portal inflammation in liver tissues of the D-GalN and LAF-treated groups. Taken together, these results demonstrate that LAF may improve plasma lipid profile and alleviate hepatic damage.
