Aralia contientalis show several beneficial effects including anti-oxidant effects. Aralia contientalis is used as a therapeutic agent to stop haemorrhages and a tonic to promoted health in Korean and Chinese medicine. The pharmacokinetic profiles of the main Aralia contientalis is still not accurately investigated. In present study, I examined the effects of water extracts of Aralia contientalis on high cholesterol diet atherosclerosis-induced rats in serum and abdominal aorta. A total of 3-week old 9 male rats of Sprague-Dawley were divided into 3 groups and fed with the basal diet (normal group), high cholesterol diet (atherosclerosis induced group) for 8 weeks, high cholesterol diet supplemented with water extracts of Aralia contientalis (Aralia contientalis group) for 2 weeks. And rats were sacrificed, serum lipid level, abodominal aortic anti-oxidant activities and lipid peroxide were measured. These results indicated that serum total cholesterl, LDL-cholesterol, triglycerides concentration significently lowered in Aralia contientalis group than high cholesterol diet group. But HDL-cholesterol concentraion significently higher in Aralia contientalis group than high cholesterol diet group.

The present study was carried out to investigate the antiobesity and hypocholesterolemic effects of Bifidobacteria animalis DY-64 (B. animalis DY-64), a lactic acid bacterium isolated from the human intestine, in rats fed a high-fat/high-cholesterol diet for 4 weeks. Forty male Sprague-Dawley rats were divided into four groups and fed either a normal (N) or high-fat/high-cholesterol (HFC) diet without or with oral administration of B. animalis DY-64 (N-BA, HFC-BA). The gain in body weight, and liver and adipose tissue weights of the HFC group were heavier than that of the HFC-BA group. Serum total cholesterol (TC), LDL-cholesterol, and leptin levels of the HFC group, which were significantly elevated compared to those of the N group, dropped by 19, 18, 21, and 13% in the HFC-BA group, respectively, whereas the serum HDL-cholesterol level markedly increased. However, serum TG, LDL-cholesterol, HDL-cholesterol, and leptin levels were not significantly different among the N groups (N, N-BA) with or without B. animalis DY-64 administration. TC and TG levels of the liver as well as the TG level of the adipose tissue were significantly reduced in the HFC-BA group. In addition, HR-LPL activity in adipose tissue was also lower in the HFC-BA group than in the HFC group. These results suggest that B. animalis DY-64 isolated from the human intestine exerts hypocholesterolemic effects by reducing serum and liver cholesterol levels and plays a role in the prevention of obesity induced by HFC diet.

Sense-line (SL), a dietary functional food, is our invention for weight loss. To evaluate such an effect of SL, we analyzed the plasma levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and weight changes after rats were fed on high fat diet with SL for 20 days. Plasma total cholesterol level and LDL-cholesterol level was decreased by 52% and 91.89% in 5% SL treated group and by 13% and 51.45% in 10% SL treated group, respectively. But HDL-cholesterol was not changed. In addition, the weight was significantly lower in SL group than in high-fat diet group (P<0.05). Our findings indicate that SL may contain compounds with actions, which can treat blood circulatory trouble as well as overweight.

Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.

This study was conducted to investigate the antioxidative effects of Paeonia lactiflora (PL) seeds on antioxidative defense system and lipid peroxidation of liver in rats fed high-cholesterol diet. Sprague-Dawley male rats weighing 100 $\pm$10g were randomly assigned into five experimental groups fed 0.5% cholesterol ; HC group which was not supplemented PL seeds extract, 0.1% methanol extract diet group (MP1 group), 0.2% methanol extract diet group (MP2 group), 0.05% ether-souble fraction diet group (EP1 group) and 0.1 % ether-souble fraction diet group (EP2 group). Experimental diets were fed ad libitum to the rats for 3 weeks. The activity of hepatic superoxide dismutase (SOD) was not significantly different among all the high cholesterol diet groups. The hepatic glutathione peroxidase (GSHpx) activity in MP2 group was increased to 27% compared to HC group. The activity of hepatic catalase (CAT) was not significantly different among the all high cholesterol diet groups. The hepatic glutathione S-transferase (GST) activity in the EP1 and EP2 groups were increased to 12% and 13%, respectively, as compared to HC group. The levels of hepatic TBARS in the MP1, MP2, EP1 and EP2 groups were reduced by 18%, 21%, 20% and 23%, respectively, as compared with HC group. The contents of lipofuscin in liver was not significantly different among all the experimental groups. The results indicated that PL seeds extract may be reduced oxidative damage by activating antioxidative defense system of hepatic in rats fed high-cholesterol diets.

The present study examined the lipid lowering and antioxidant activity of Paecilomyces tenuipes. Eight week-old male Sprague-Dawley rats were fed one of the three diets, a reference diet without cholesterol addition (NC), a high fat (17 g/ 100 g)-high cholesterol (1 g/100 g) diet (HC) and a HC diet supplemented with 3% P. tenuipes (PT) for 30 days. Total lipid and total cholesterol were reduced significantly by 33 and 37%, respectively, in the PT diet group compared with controls. A similar reduction was found for low density lipoprotein (LDL) cholesterol levels, while plasma high density lipoprotein (HDL) cholesterol and triglyceride (TG) concentrations were not significantly different among groups. Hepatic total lipid and total cholesterol levels, but not hepatic TG levels, were significantly decreased in the PT group compared to the HC group. The administration of P. tenuipes increased the plasma total antioxidant potential and decreased the levels of lipid peroxidation. These results suggest that P. tenuipes exerts significant health benefits through the modulation of physiological functions including a variety of atherogenic lipid profiles and antioxidants in hypercholesterolemia.

This study examined the antioxidant activity and lipid composition of rats fed a high fat-high cholesterol diet containing Salvia plebeia water extract. Three levels (50 mg/kg, 200 mg/kg, 500 mg/kg) of Salvia plebeia water extract were administered to seven weeks old male Sprague Dawley rats for four weeks. The activity of glutathione peroxidase in serum was high in all groups that received the Salvia plebeia water extract (p<0.05). The glutathione reductase activity was high (p<0.05) in groups that received 50 mg/kg and 500 mg/kg of Salvia plebeia water extract. When rats received Salvia plebeia water extract, the content of MDA (malondialdehyde) in the serum and liver was low in all groups. In addition, the serum total lipid, triglyceride, total cholesterol and LDL-cholesterol contents decreased significantly (p<0.05). Total cholesterol and triglyceride levels in the liver were significantly lower in the group that received the Salvia plebeia water extract than in the control group (p<0.05). Salvia plebeia water extract improves lipid metabolism and it almost meets with the increase of antioxidant activity and peroxide formation reduction. Based on these results, supplemented of a high fat-hypercholesterol diet with Salvia plebeia can increase antioxidant activity and depress peroxide formation in serum, as well as liver cholesterol and triglycerides.

BACKGROUND/OBJECTIVES: High levels of plasma low-density lipoprotein (LDL) cholesterol are an important determinant of atherosclerotic lesion formation. The disruption of cholesterol efflux or reverse cholesterol transport (RCT) in peripheral tissues and macrophages may promote atherogenesis. The aim of the current study was to examine whether bioactive ellagic acid, a functional food component, improved RCT functionality and high-density lipoprotein (HDL) function in diet-induced atherogenesis of apolipoproteins E (apoE) knockout (KO) mice. MATERIALS/METHODS: Wild type mice and apoE KO mice were fed a high-cholesterol Paigen diet for 10 weeks to induce hypercholesterolemia and atherosclerosis, and concomitantly received 10 mg/kg ellagic acid via gavage. RESULTS: Supplying ellagic acid enhanced induction of apoE and ATP-binding cassette (ABC) transporter G1 in oxidized LDL-exposed macrophages, facilitating cholesterol efflux associated with RCT. Oral administration of ellagic acid to apoE KO mice fed on Paigen diet improved hypercholesterolemia with reduced atherogenic index. This compound enhanced the expression of ABC transporters in peritoneal macrophages isolated from apoE KO mice fed on Paigen diet, indicating increased cholesterol efflux. Plasma levels of cholesterol ester transport protein and phospholipid transport protein involved in RCT were elevated in mice lack of apoE gene, which was substantially reduced by supplementing ellagic acid to Paigen diet-fed mice. In addition, ellagic acid attenuated hepatic lipid accumulation in apoE KO mice, evidenced by staining of hematoxylin and eosin and oil red O. Furthermore, the supplementation of 10 mg/kg ellagic acid favorably influenced the transcriptional levels of hepatic LDL receptor and scavenger receptor-B1 in Paigen diet-fed apoE KO mice. CONCLUSION: Ellagic acid may be an athero-protective dietary compound encumbering diet-induced atherogenesis though improving the RCT functionality.
