Purpose : The purpose of this study was to analyze the correlations among bone mineral density(BMD), serum lipid levels, and cognitive function in the elderly with dementia. Methods : We recruited seventy elderly with dementia(men=35, women=35) to participate in the Korean mini mental state examination(K-MMSE). Their T-scores and serum lipid levels were analyzed for correlation analysis. Results : The results of this study showed that there are significant correlations between cognitive function and three factors BMD, low-density lipoprotein cholesterol(LDL-C) level, and total cholesterol(TC) level. The cognitive function scores increased proportionally with BMD but were inversely proportional to LDL-C and TC levels. There were no significant relations among cognitive function, high-density lipoprotein cholesterol(HDL-C) level, and triglyceride(TG) level. Conclusion : These results indicate that there is a direct proportionality between cognitive function and BMD and inverse proportionalities between cognitive function and LDL-C level and between cognitive function and TC level. Therefore, these levels can be indices for preventing and predicting dementia.

Objectives : The object of this study was to observe the effects of Hwangryungeehwang-tang (HRGHT), which has traditionally been used in Korean medicine for treating diabetes, by administering aqueous extracts to streptozotocin-induced diabetic rats. Methods : Three different dosages of HRGHT extracts were orally administered once a day for 28 days from 3 weeks after streptozotocin treatment (60 mg/kg, single intraperitoneally administered). 6 groups, of 8 rats per group were used in the present study, selected 3 weeks after streptozotocin treatment based on blood glucose levels and body weights. Changes to the body weights, blood glucose levels, serum low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride and total cholesterol levels were observed, as well as changes on the pancreatic, hepatic and kidney malondialdehyde (MDA) contents for lipid peroxidation and glutathione contents for antioxidant effects. The results were compared with a potent antioxidant silymarin 100 mg/kg, of which the effects on streptozotocin-induced diabetes and related complications are already confirmed. Results : Significant decrease of blood glucose levels, serum LDL, total cholesterol, triglyceride levels, pancreatic, hepatic and renal MDA contents and significant increase of body weights, serum HDL levels, pancreatic, hepatic and renal GSH contents were detected in HRGHT extracts 100 and 200 mg/kg administered groups as compared to the streptozotocin control group. The lowest dosage of HRGHT treated group, 50 mg/kg, did not show any favorable effects as compared with the streptozotocin control. Conclusions : HRGHT has favorable effects on diabetes and related hyperlipidemia. Therefore, more detailed mechanism studies should be conduced in future with efficacy tests of individual herbal compositions of HRGHT and screening of the biological active compounds in the herbs.

Defatted methanol extracts of the medicinal plants, Rubus coreanus Miq. (RC) and Atractylodes japonica Koidzumi (AJ) were added at the levels of 0.1, 0.5, or $2\%$ (w/w) to high cholesterol diets and fed to ovariectomized Sprague-Dawley female rats, weighing 212.6 $\pm$ 1.8 g for four weeks. Weight gains were lower in RC and AJ groups than the control group, but there were no changes in uterus weights. Serum levels of triglyceride decreased by 20-$27\%$ in the experimental groups fed $0.1\%$ of each extract (O.1RC and O.1AJ), compared with that of control (Ovx). Serum cholesterol levels were not changed in the RC groups but increased in the group fed $2\%$ of the AJ extract. Liver levels of cholesterol and triglyceride were reduced in both the RC and AJ groups. Microscopic observation revealed that there were no morphological alterations in liver, lung, heart, spleen and kidney tissues of the experimental groups. Plasma levels of albumin, BUN, creatinine, sodium, potassium and phosphate in the IRC and AJ groups were in normal ranges. Serum GOT and GPT activities were, however, higher in the 2.0AJ than Ovx group. These results suggest that the extracts of the Rubus coreanus Miq. and Atractylodes japonica Koidzumi at dietary levels as low as $0.1\%$ may be utilized as hypotriglyceridemic ingredients for functional foods.

■ Objectives The berries of Schisandra chinensis (Schisandra Fructus) are given the name Omiza in Koreane(五味子), and have been used asremedies for many ailments: to resist infections, increase skin health, and combat insomnia, coughing, and thirst. This study was designed to investigate the effects of Schisandra Fructus hexane fraction (SFH) on serum lipid levels in Hyperlipidemic mice. ■ Methods In this experiment, effects on total cholesterol, HDL-cholesterol, triglyceride, AST, ALT, fasting blood glucose in serum were measured. And in addition, histopathological and gene expression changes in liver tissue was also observed. ■ Results SFH did not affects weight gain, serum AST and ALT in hyperlipidemic mice. Oral administration of SFH lowered levels of total cholesterol and triglyceride, which were elevated by induction of hyperlipidemia. Finally, administration of SFH lowered fasting blood glucose significantly. And SFH also ameliorates anti-oxidative stress systems in internal organs which play key role in disease prevention. ■ Conclusion Results in our study suggest that SFH can prevent obese through regulation of dyslipidemia and hyperglycaemia.

The effects of 3% Cortex Eucommiae extracts on serum lipid contents were evaluated in rats. Forty-two male Sprague-Dawley rats weighing $100{\pm}10g$ were divided into seven groups and fed different fat diets for four weeks. Each group was administered with following group: Control, basal fat diet, saturated fat diet and unsaturated fat diet respectively was fed 1% cholesterol, Cortex Eucommiae extracts 3%. The contents of serum lipid contents triglyceride in the basal fat diet group were higher than those of control group. The contents of total-cholesterol in serum of the saturated fat diet group was significantly higher than other group. The contents of HDL-cholesterol in serum of the 3% Cortex Eucommiae extract group were higher than those other fat diet group. The contents of LDL-cholesterol in serum of the 3% Cortex Eucommiae ex1ract group was lower than other fat diet groups. These results suggest that 3% Cortex Eucommiae extract group may reduced elevated levels of serum lipid contents in rats different fed fat diet.

The effects of fruiting body of Cordyceps militaris on the growth, the food intake, the food efficiency ratio, the lipid metabolism, the serum protein level ad enzyme activity in male rats were studied. Sprague-Dawley rats were fed four types of diets for five weeks, respectiely: a control diet, a control diet supplemented with 2%, 3% or 4% fruiting body of Cordyceps militaris(CF) powder. In rats fed 2% or 3% CF diets the body weight gain, the food intake, the concentratons of hepatic triglyceride and serum LDL-cholesterol, the atherogenic index, and the total lipid, total cholesterol, triglyceride and phospholipid in serum were similar to those in rats fed the control diet. Whereas, in 4% CF diet these were significantly decrased. But the all CF diets feeding could not decrease the food efficiency ratio, the weights of liver, pancreas, spleen, kidney and heart, and the concentration of serum HDL-cholesterol. Also, it was shown that the concentrations of glucose, total protein, albumin, urea and creatinine, and the GOT, GPT, LDH, ${\gamma}$-GTP and ALP activities were the same levels in serum of rats of fed all the experimental diets.

This study was intended to figure out the interrelationship among body fat distribution serum insulin and lipids levels. One hundred forty four adult female from Chinju area were participated in this study. The survey was conducted between December 17, 1990-February 27, 1991, . The results are as follows : Wiast/hip girth ratio(WHR) and waist/thigh girth ratio(WTR) were increased with age and positively correlated with body mass index(BMI). It appeared that the prevalence of obesity in terms of BMI was higher in upper body type than intermediate or lower body type women. Correlation analyese indicated that serum triglyceride level seemed to be more closely associated with BMI and other body fat distribution indices. Analyses of the anthropometric data serum lipids and insulin were carried out by dividing the sample into three body type groups-upper body type women(WHR$\geq$0, .87) intermediate body type women(0.82$\leq$WHR$\leq$0.86) and low body type women(WHR$\leq$0.81) Age weight BMI RBW percentage of body fat serum insulin triglyceride cholesterol level of upper body type women were significnatly higher than that of intermediate or lower body type women(p<0.05) HDL-cholesterol was significantly lower in upper body type women. These results suggested that body fat distribution would be relevant to chronic metabolic diseases.

The effects of the vegetable diet on the levels of the serum lipids, particularly the level of the serum total cholesterol which is most concerned with coronary heart disease (CHD) were investigated in 30 male SDA (Seventh Day Adventists) group and 30 male omnivorous group (control group). SDA participated in this study intaked relatively few animal origin foods whereas they intaked plant origin foods largely; they seldom or sometimes intaked meats, fishes, butter, margarine, beverages and coffee, but often unrefined cereals, legumes, vegetables and fruits. In the both systolic pressure and diastolic pressure, there was no difference between two groups. The levels of the serum total cholesterol, triglyceride and phospholipid were lower in SDA group than in the omnivorous group. Among them the difference was statistically significant in the level of the serum total cholesterol. HDL-cholesterol was more or less higher in SDA group than in the omnivorous group, but the difference was no significant. The result that SDA group had lower level of the serum total cholesterol than the omnivorous group suggested that that they might be less prone to CHD than the omnivorous group. Though this possibility, however, was derived from the fact of the lower level of serum total cholesterol of SDA group, it might by partly responsible for their habit that they never smoke and drink alcohols and coffee.

This study was undertaken to investigate the effect of Cassia tora ethanol extract on the lipid levels in serum and liver of rats fed high cholesterol diet. Experimental rats were divided into the following 4 groups: normal diet group, high cholesterol diet group, high choleslerol-0.25% C. tora ethanol extract group and high cholesterol-0.5% C. tora ethanol extract group. After 4 weeks, rats were sacrificed and analyzed the serum lipid profiles, activities of serum alanine aminotransferase (AST), aspartate aminotransferase (ALT), hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme (ME). It was also determined the contents of total cholesterol, triglyceride and thiobarbituric acid reactive substances (TBARS) in liver. There was no difference in weight gains between experimental groups. The concentrations of serum total cholesterol, free cholesterol, triglyceride and free fatty acid were tended to be decreased in C. tora groups compared with control group. HDL-cholesterol concentration was significantly decreased in high cholesterol diet group and slightly increased by C. tora ethanol extract feeding. The contents of liver cholesterol and triglyceride were higher in high cholesterol diet group than normal group, but significantly decreased by feeding of C. tora ethanol extract. Supplementation of 0.5% C. tora extract decreased significantly the activities of hepatic G6PDH and ME. Activities of serum AST, ALT and contents of liver TBARS were tended to be increased with high cholesterol diet and reduced by C. tora ethanol extract supplementation but had not significance. These results suggest that C. tora ethanol extract may exert a lipid lowering effect in serum and liver of rats.

The purpose of this study was to investigate the effects of diet composition on serum leptin and lipids profiles in rats. At the baseline, seven 4-week-old Sprague-Dawley rats, male, were sacrificed and the remaining rats were divided into five groups and each group was fed one of the following five dietary regiments for 2 weeks and 6 weeks;the control diet AIN76(CAL, n=2l), high-carbonhydrate(rice)(HCR, n=2l), high-carbohydrate(flour)(HCF, n=2l), high-fat(corn oil)(HFO, n=2l), high-fat(beef tallow)(HFB, n=2l). Serum leptin was determined by a double antibody ELISA assay at the baseline(n=7), 6 week(n=35) and 10 week of age(n=70). At 6 weeks of age, the increase in the Food Efficiency Ratio(FER) was related to adipocyte hyperplasia in rats on HFB diets. The serum triglyceride, total cholesterol, and LDL-cholesterol increased significantly in HFB group, and decreased in HFO group compared to control group. The HFC group showed significant increase in serum triglyceride level compared with control group. After 2 weeks and 6 weeks, noticeably high increases in epididymal adipose tissue fat cell mass and numbers were observed with the HFB fed group. Serum leptin levels increased as body weight increased over the period of time(4weeks; 1.50$\pm$0.13ng/ml versus 10weeks; 2.08$\pm$-.13ng/ml). And this result shows that there are 193% higher in rats fed high fat-beef tallow diet than the control diet. Serum leptin levels of the HFB group(4.01$\pm$0.39mg/ml) were significantly higher than that of the HFO(2.06$\pm$0.5613ng/ml), CAL(2.08$\pm$0.1313ng/ml), HCR(2.41$\pm$0.2113ng/ml) and HCF(2.80$\pm$0.4713ng/ml) at p<0.05. The serum leptin concentration was positively correlated with the amount of epididymal fat pads(r=0.47 p<0.01), serum triglyceride(r=0.49, p<0.001), tatal cholesterol(r=0.48, p<0.001), LDL-cholesterol(r=0.58, p<0.001), atherogenic index(r=0.67, p<0.001), and inversely correlated with HDL-cholesterol(r=-0.65, p<0.001). In conclusion, the changes in composition of dietary fat and carbohydrate intake could affect changes in concentration of serum lipids and leptin. Especially, the high-fat diet with animal fat source could increase circulating leptin level. (Korean J Nutrition 34(2) : 123-131, 2001)
