The purpose of this study was to investigate the potential hypolipidemic effect of adlay extract in streptozotocin-induced diabetic rats. Fifty six rats were fed either a control diet or adlay extract diets of : Methanol 1%(Ml%) ; Methanol 2%(M2%) ; Methanol 4%(M4%) ; Chloroform-Methanol 1%(CMl%) ; Chloroform-Methanol 2%(CM2%) ; Chloroform-Methanol 4%(CM4%) for 3 weeks. The amount of extracts added was 1%, 2% or 4% by diet weight respectively. The levels of glucose, total cholesterol(TC), high-density-lipoprotein cholesterol (HDL-C), free-fatty acid(FFA) and triglyceride(TG) in plasma, liver and skeletal muscle were compared. Among diabetic rats, there were no significant differences in the plasma level of glucose and TC regardless of a different extraction procedure or different amount of extracts added. While the plasma 7G level tended to increase with times passed in diabetic control group, was not increased with times passed in CM groups and was significantly lower in CM groups at 3rd week. Compared to the diabetic control group, the levels of FFA tended to be lower in all M groups and were not different in all CM groups. The levels of HDL-cholesterol were not different in all M groups and were significantly lower in all CM groups than diabetic control group. Compared to diabetic control group, liver triglyceride level was lower in M4% group and no significant difference was seen in Ml%, M2% and all CM groups. Muscle triglyceride level tended to be lower in Ml%, M2% and CM2% group and significantly was lower in M4% and CM4% group. Thus, it can be suggested that a CM extract of adllay could have a potential hypotriglyceridemic effect on diabetic subjects. (Korean J Nutrition 31(5) : 921∼926, 1998)

This research was planned and executed to evaluate how the composition of Yak-sun(oriental diet therapy) can effect health conditions of people who are suffering from diet-related diseases like obesity and hyperlipidemia by taking Yak-sun in a form of nutritional supplement with our daily meals. We produced Jangswucha with Koekac, Sansa, Heshouwu, Wulong and evaluated how this tea effects on serum lipids and oxidative stress by clinical practices. Also we examined physical characteristics of Jangswucha. Brix, pH and titratable acidity of Jangswucha were 1.4, 5.50 and 0.05%. With this observation, we found out that this tea has significant effect on increase of HDL-cholesterol, decrease of LDL-cholesterol concentration in serum. Also this tea significant effect on decrease oxidative stress and homocystein content. We think that scientific and objective evaluation was done on the components of Yak-sun tea prescription. We concluded that we could apply the components not only in a form of tea, but also in other forms of various food. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other food and will also be a steppingstone for medicinal herbs to step foot in the field of functional food research, which already draws sizable attention world-wide.

The effect of milk in low and high cholesterol diet was invesigated on serum cholesterol metabolism and lipid contents of serum, aorta, liver of rats. Weanling male Sprague-Dawley rats were divided into low(0.01% w/w) and high(1.01% w/w) cholesterol-diets groups. Low cholesterol groups subdivided into four groups ; control group was given water and three milk groups were given low heat milk(LM), ultra-high heat milk(HM), and powder milk(PM), respectivily, instead of water. High cholesterol groups were consisted of three groups ; control, LM, and HM groups. After feeding these experimental diets for six weeks, lipid levels were measured in serum and tissure and dried feces were analyzed for neutral and acidic sterols. Results obtained from this study are as follows : 1) Nutrient intakes, body weight gains and aorta weights did not differ among groups, but liver weights were higher in high cholesterol fed rats than low cholesterol fed rats. 2) Serum protein contents were increased independently by intakes of high cholesterol and milk. 3) Serum total cholesterol and triglyceride levels were increased but phospholipid levels and HDL-cholesterol/total-cholesterol ratios were decreased by high cholesterol in diet. And milk supplementation decreased serum total cholesterol and triglyceride levels but increased phospholipid levels and HDL-cholesterol/total-cholesterol ratios. 4) Contents of cholesterol and triglyceride in aorta and liver were elevated by dietary high cholesterol and lowered by consumption of all three types of milk. 5) Levels of cholesterol and triglyceride among serum, aorta and liver were highly correlated (r=0.7-0.9, p<0.001). 6) Fecal excretion of total sterols was three times high in high cholesterol group, compared with low cholesterol groups and were increased about 20% by milk consumption. 7) The effects of milk were more pronouncely shown in low cholesterol groups and mostly confined to LM and HM groups, rarely shown in PM group. It is concluded from the present study that milk had the hypolipidemic as well as hypocholes terolemic effect, which appears to be mediated through increased fecal bile acid excretion. But the effect is likely to be shaded by excess consumption of dietary cholesterol and was almost absent in powder milk.

To control blood glucose level as close to normal is a major goal of treatment of diabetes mellitus. Hyperglycemia and hyperlipidemia are the major risk factors for cardiovascular complications, the major cause of immature death among the patients with type 2 diabetes. The purpose of this study is to determine the hypoglycemic and hypolipidemic effects of Salicornia herbacea in animal model of type 2 diabetes and to investigate the possible mechanisms for the beneficial effects of S. herbacea. S. herbacea was extracted with 70% ethanol and desalted with 100% ethanol. Three week-old db/db mice (C57BL/KsJ, n=16) were fed AIN-93G semipurified diet or diet containing 1% desalted ethanol extract of S. herbacea for 6 weeks after 1 week of adaptation. Fasting plasma glucose, triglyceride, and total cholesterol were measured by enzymatic methods and blood glycated hemoglobin ($HbA_{1C}$) by the chromatographic method. Body weight and food intake of S. herbacea group were not significantly different from those of the control group. Fasting plasma glucose and blood glycated hemoglobin levels tended to be lowered by S. herbacea treatment. Consumption of S. herbacea extract significantly decreased plasma triglyceride and cholesterol levels (p<0.05). The inhibition of S. herbacea extract against yeast ${\alpha}$-glucosidase was 31.9% of that of acarbose at the concentration of 0.5 mg/mL in vitro. The inhibitory activity of ethanol extract of S. herbacea against porcine pancreatic lipase was 59.0% of that of orlistat at the concentration of 0.25 mg/mL in vitro. Thus, these results suggest that S. herbacea could be effective in controlling hyperlipidemia by inhibition of pancreatic lipase in animal model of type 2 diabetes.

Saururus chinensis Baill was reported to inhibit ${\alpha}-glucosidase$ in vitro and flatten postprandial increase in blood glucose in streptozotocin (STZ)-induced diabetic rats. We studied the effect of chronic consumption of S. chinensis Baill on blood glucose and lipid profile in STZ-induced diabetic male rats fed high fat diet. Male rats weighing 100-120 g were fed 30% fat diet with and without 10% freeze-dried leaves of S. chinensis Baill for 7 weeks after 1 week of adaptation. The rats were rendered diabetic by intravenous injection of STZ (60 mg/kg) after 6-week feeding of the assigned diets. At 1 week after the injection, the rats were sacrificed after an overnight fast. Plasma glucose ($380.2{\pm}14.4mg/dL$), total cholesterol ($93.9{\pm}7.9mg/dL$) and triglyceride levels ($123.6{\pm}7.5mg/dL$) of the S. chinensis Baill group were significantly lower than those of the control group ($418.1{\pm}12.0mg/dL,\;119.9{\pm}9.4mg/dL,\;152.0{\pm}10.3mg/dL$, respectively, p<0.05). Chronic consumption of S. chinesis Baill significantly decreased maltase activity of the small intestinal mucosa ($120.1{\pm}8.7U/g$) protein compared with the control group ($96.8{\pm}7.0U/g protein, p<0.05). These results suggest that S. chinensis Baill have hypoglycemic and hypolipidemic effects by inhibiting ${\alpha}-glucosidase$ activity in the animal model of diabetes mellitus.

Panax ginseng C.A. Meyer (Panax ginseng) has been used for several thousand years to prolong longevity in Asian countries. Ginsenosides are the most active components isolated from ginseng and belong to damarane saponin which are separated into protopanaxadiol and protopanaxtriol. To evaluate the complex effect of ginsenoside in apo E null mice, ginseng extract were intraperioneally (i.p.) injected and provided high-cholesterol diet for 12 weeks. Ginseng extract came from were i.p. injected with dose of 100 mg/kg/day for 4 weeks in the last experimental duration. Ginseng extract used experiment was abundant Rb1, Rc, Re, and Rg1 and PD：PT ratio was 1.2. The high-cholesterol diet induced liver damage was significantly reduced by ginseng extract. Results from plasma lipid profiles and atherogenic index were improved by ginseng extracts. The GE group significantly decreased plasma TG and TC by 73% and 61% compared to apo E (-/-) group. Also ginseng extract tend to decrease lipid profiles and lipidperoxidation contents in liver and heart. Ginseng extract with an abundant amount of Rg1 significantly suppressed the apoptosis induction of cardiac tissue. In conclusion, ginseng extract (PD：PT = 1) was improved lipid profiles and anti-oxidant effects.

Objectives : This study aimed to elucidate the effects of TBE on hyperlipidemia. Methods : We studied the effects of TBE on hyperlipidemia through gene expressions related with lipid metabolism and serum triglyceride as well as total and HDL-cholesterol levels, and perceived histological changes. Results : The present studies demonstrate that TBE can reduce the rise in plasma cholesterol and TG levels induced by a high-cholesterol diet and also reverse pre-established hypercholesterolemia and hypertriglycemia. In the TBE group total cholesterol levels decreased, TG levels decreased, but HDL-cholesterol levels also decreased. In the analysis of absolute and relative liver weight, TBE inhibited the weight gain induced by a high-cholesterol diet. In the histological observations, lipid droplet and apoptotic change in the TBE treated group were less compared with the control group. In the serum biochemical analysis, a difference of serum AST and ALT changes among groups was not shown, but TG and total cholesterol levels were less and HDL level decreased compared with the control group. In the gene expression related with TG and cholesterol metabolism, DGAT decreased slightly but ACAT decreased more as compared with control and Lipidil groups. Conclusion : From this study, we can infer that TBE possesses a hypolipidemic effect by inhibiting the intestinal absorption and storage of exogenous and endogenous cholesterol.

This study was conducted to investigate the effects of shellfish hydrolysate on lipid metabolism in rats fed high fat diet. Male Sprague-Dawley rate weighting approximately 110g were fed basal control diet, high fat diet and high fat diet plus 4 different shellfish hydrolyates for 4 weeks. The shellfish hydrolysates from the different sources, were oyster, hard-shelled mussel, little neck clam and march clam. After 4 weeks, serum GOT, GPT, ${\gamma}$-GTP, triglyceride and total cholesterol was significantly decreased in shellfish hydrolysates supplementation with high fat diet compared to basal control and high-fat group(p<0.05). The total lipid and cholesterol content in liver showed significant decrease(p, 0.05). There were no different in serum GPT, HDL-cholesterol, liver total cholesterol and lipid of rats between basal control diet and high-fat diet. The unsaturated fatty acids, specific components of shellfishes were a little components in shellfish hydrolysate as they were a low and not different among the groups and were most well reflected in liver and plasma. Considering digestive and absorptive process of in human body, it was assumed that the hypolipidemic effect of shellfish was not under the influence of unsaturated fatty acids but the other components, peptides, taurine and betaine and so on was detected in the process of hyperlipidemia induced by high-fat diet.
