  • 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). ${\gamma}$-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.

  • This study was conducted to determine the effects of fermented water extracts from Ligularia fischeri (LAF) on reduction of hepatotoxicity induced by ethanol in rats. Ethanol-treated Sprague-Dawley rats were divided into the following eight groups: ethanol-treated group (control), ethanol and ursodeoxycholic acid-treated group (positive control), ethanol and non-fermented water extracts from Ligularia fischeri (LA)-treated groups [100, 200, and 400 mg/kg BW (body weight)], ethanol and LAF-treated groups (100, 200, and 400 mg/kg BW). ${\gamma}$-Glutamyl transferase activities of the ethanol+LA-treated (100, 200, and 400 mg/kg BW) groups and ethanol+LAF-treated (400 mg/kg BW) group decreased significantly compared to those in the control group (P<0.05). Aspartate aminotransferase activities of the ethanol+LAF-treated (100, 200, and 400 mg/kg BW) groups and ethanol+LA-treated (200 and 400 mg/kg BW) groups decreased significantly compared to those in the control group (P<0.05). Alanine aminotransferase and lactate dehydrogenase activities of all groups significantly decreased compared to those in the control group (P<0.05). The total cholesterol, low density lipoprotein-cholesterol, and triglyceride levels of all groups tended to decrease compared to those in the control group, but the differences were not significant. Superoxide dismutase activity of liver tissues was enhanced in the ethanol+LAF-treated (400 mg/kg BW) group (P<0.05). The contents of malondialdehyde in liver tissues decreased in the ethanol+LAF-treated groups (P<0.05). All treated groups showed well preserved lobular architectures with no evidence of steatosis or liver damage compared to the control group. As the results of this study, LAF may improve the plasma lipid profile and alleviate hepatic damage by ethanol.

  • Purpose : Chronic renal failure is often accompanied by severe dyslipidemia, a known risk factor for cardiovascular disease. Lipoprotein(a) [Lp(a)] has recently been characterized as a risk factor for atherosclerosis and thrombosis. Cardiovascular disease is the leading cause of death in adult patients on dialysis. However, there are only limited data available concerning risk factors for atherosclerosis in uremic children. We have measured serum levels of lipids, lipoproteins, apolipoproteins and Lp(a) in uremic children with maintenance dialysis. Methods : Ten uremic children with hemodialysis (HD) and 14 with peritoneal dialysis (PD) in our dialysis unit were included in this study. The mean age of HD patients was $162{\pm}59$ months and the male to female ratio was 7:3. The mean age and sex ratio of PD patients were $123{\pm}63$ months and 6:8, respectively. The levels of cholesterol, triglyceride, lipoproteins, apolipoproteins and Lp(a) were measured from serum sampled after 14 hours of fasting. The normal control levels were cited from 2 articles presenting the normal blood lipid and lipoprotein levels of primary school and middle school children in Korea. Results : There was no difference in age, sex ratio, body mass index and duration of dialysis between the HD and the PD group. The serum concentration of the cholesterol, triglyceride and apolipoprotein B were significantly elevated in dialysis patients compared with normal subjects. The serum level of Lp(a) was significantly elevated in only PD group. The serum Lp(a) level was below 30 mg/dl in 13 and above 30 mg/dl in 11 patients. The serum albumin level was significantly decreased in high Lp(a) group than in low Lp(a) group. Conclusion : The uremic children receiving dialysis reveal abnormal serum lipid and lipoprotein profiles. These results suggest that they have a higher risk for coronary heart disease, although there has been no clinical evidence of coronary heart disease at present. A long-term follow-up study of these children to clarify the suggestion should be started now.

  • This study was done in order to evaluate the of effects on the blood lipid profiles, the body weight and body fat in 28 healthy female volunteers who had over 30% body fat by the long term intake of red ginseng product. Subjects were divided into four groups (placebo group n=7, red ginseng product group; n=7, exorcise group; n=7, exercise & red ginseng product group; n=7). Blood sampling and measuring of the body fat were taken by pre-treatment, 3 weeks, and after 12 weeks. Statistical techniques for data analysis were applied one-way ANOVA and repeated measures ANOVA. The 5% level of significance was used as the critical level for this study. In summary of results, total cholesterol, triglyceride and low density lipoproprotein cholesterol were reduced in three groups (red ginseng product group, p<0.001, exercise group, p<0.01 ; exercise & red ginseng product group, p<0.001) except placebo group. HDL-C was improved in three groups (red ginseng product group, p<0.05; exercise group, p<0.01; exercise & red ginseng product group, p<0.001) except placebo group. Body weight, percent body fat and body fat mass were reduced in three groups (red ginseng product group, p<0.01, exercise group, p<0.01 ; exercise & red ginseng product group, p<0.001) except placebo group. Finally, lean body mass was improved in three groups (red ginseng product group, p<0.05; exercise group, p<0.01; exercise & red ginseng product group, p<0.001) except placebo group.
