To investigate the effects of Ixeris sonchifolia Hance diets on serum and hepatic lipid levles and enzyme activities in rats administered with ethanol chronically, Sprague-Dawley male rats were AIN-76 diet(control), control diet plus ethanol, control plus Ixeris sonchifolia Hance diet, or control plus Ixeris sonchifolia Hance diet plus ethanol for 30 days. Ixeris sonchifolia Hance diets significantly decreased the serum total cholesterol, triglyceride, LDL-cholesterol, and GOT levels that were increased due to the chronic ethanol administration. In addition, Ixeris sonchifolia Hance diets significantly decreased the liver triglyceride and total lipid levels that were increased due to the ethanol administration. The present findings, combined with previous data showing differences in the effects of cabbage diets having a high or a low level of GABA on the lipid levels and the serum Y-GPT activity of rats(Cha and OH[2000] J. Korean Soc. Food Sci. Nutr. 29, 500-505) raise the possibility that GABA in plants could have a nytraceutical role in the recovery of chronic alcohol-related diseases.

This study investigated the synergy effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system of rats on hypercholesterol diets. Sprague-Dawley male rats were fed either a hypercholesterol diet with water or a hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine. The experimental groups consisted of the control group (CO), the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES), and the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). Eleutherococcus senticosus was extracted, made into 0.5% solution, and fed to the ES and ESC groups. A 3% carnitine diet was supplied to the ESC group. Hypercholesterol diets contained 18% beef tallow and 5% cholesterol. After 4 weeks of administering these diets, serum and liver were obtained and the level of serum lipid and the activities of GOT and GPT were measured. In addition, the level of liver lipid and TBARS and the activity of GSH-Px were measured. The results were as follows: 1) Weight gain and FER in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC) was low significantly(P<0.05). 2) In the groups supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and the group supplied with hot water soluble extract from Eleutherocorcus senticosus and dietarty carnitine(ESC), total serum cholesterol levels were both significantly low (P<0.05,P.0.01). 3) Serum GOT activity was significantly low(P<0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietary carnitine(ESC). There was no difference between serum GPT activity in the control group and the groups supplied with hot water soluble extract from Eleutherococcus senticosus or dietary carnitine. 4) Liver triglyceride was low (P.0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). No difference was observed in other lipid composition, TBARS level, and GSH-px activity in liver between the control group and the experimental groups. In summary, the effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system (such as weight gain, FER, total serum cholesterol and liver triglyceride) were low when Eleutherococcus senticosus and dietarty carnitine were supplied simultaneously.

Objectives: Though overt thyroid dysfunction is well recognized to affect serum lipid profiles and obesity, there are conflicting reports on the effect of subclinical hypothyroidism on serum lipid profiles and obesity. In most reports, the definition of the upper normal limit of serum thyroid stimulation hormone (TSH) of 4.0${\sim}$5.0mU/L has been used to diagnose. However, recent studies have suggested a much lower TSH cut off with an upper limit of 2.5mU/L, because >95% of rigorously screened normal euthyroid volunteers had serum TSH values between 0.4 and 2.5mU/L. Therefore we defined subclinical hypothyroidism as a TSH level greater than 2.5mU/L. We sought to evaluate the correlations of subclinical hypothyroidism with obesity index and serum lipid profiles Methods: TSH levels were measured in 6190 men and 4223 women that participated in health examination and free T4, lipid profiles (total-cholesterol, triglyceride, LDL-C), and obesity index (body mass index, body fat, waist circumference, C-reactive protein) were also measured. Results: There were significant differences of triglyceride between subclinical hypothyroidism men and normal control subjects. In women, there were also significant differences of triglyceride and LDL-C between subclinical hypothyroidism and normal control subjects. Subclinical hypothyroidism women showed significant correlations of TSH with total cholesterol, LDL-C, triglyceride, and C-reactive protein. Subclinical hypothyroidism men and women with a TSH level 2.5${\sim}$4.0mU/L had significant differences of triglyceride and body fat. In men, there were significant differences of waist circumference andC-reactive protein. In women, there were significant differences of LDL-C. Conclusions: We have demonstrated correlations of subclinical hypothyroidism with serum lipid profiles and obesity index. These findings suggested that subclinical hypothyroidism people had an increased risk of dyslipidemia and obesity. Subclinical hypothyroidism people with a TSH level 2.5${\sim}$4.0mU/L may be also considered suspect since it may signal a case of evolving thyroid underactivity eligible to be prevented.

The purpose of this study was to investigate the correlations among the anthropometry, serum lipid levels and nutrient intake in Korean female university students. The subjects were 119 female students at a university located in Incheon. This study was conducted using a self-administered questionnaire. Anthropometric data were measured and blood lipid levels were analyzed. Nutrient intake collected from 3 day-recalls was analyzed by the Computer Aided Nutritional Analysis Program. The data were analyzed by SPSS 10.0 program. Average age, height and weight of the subjects were 20.9 years, 160.1cm and 54.3kg, respectively. Average serum TG (triglyceride), total cholesterol, HDL-C (high density lipoprotein-cholesterol) and LDL-C (low density lipoprotein-cholesterol) levels of the subjects were 69.47mg/dl, 146.85 mg/dl, 50.49mg/dl and 82.52mg/dl, respectively. Average AI (atherogenic index) of the subjects was 2.03, which was in the normal range based on risk values. Average intake of most nutrients except protein, vitamin B$_1$, vitamin C and phosphorus were lower than the Korean RDA. Especially calcium and iron intakes of the subjects were under 65% of the Korean RDA. Serum TG, total cholesterol and LDL-C levels were negatively correlated with DBP (diastolic blood pressure). HDL-C/LDL-C and HDL-C/total cholesterol were positively correlated with height. Age was positively correlated with phosphorus intake. DBP of the subjects was positively correlated with calcium and iron intakes. Serum TG level was positively correlated with total cholesterol, HDL-C, LDL-C and AI, while negatively correlated with HDL-C/total cholesterol. Total cholesterol level was positively correlated with HDL-C, LDL-C and AI, while negatively correlated with HDL-C/LDL-C, HDL-C/total cholesterol. HDL-C level was positively correlated with LDL-C, HDL-C/LDL-C and HDL-C/total cholesterol, while negatively correlated with AI. LDL-C level was negatively correlated with HDL-C/LDL-C and HDL-C/total cholesterol, while positively correlated with AI HDL-C/LDL-C ratio was positively correlated with HDL-C/total cholesterol and AI. HDL-C/total cholesterol was negatively correlated with AI. Fat intake was positively correlated with total cholesterol, HDL-C level, and vitamin B$_2$ intake was positively correlated with TG, HDL-C/LDL-C. Therefore, nutrition education is necessary for female university students to promote the lipid profile and to optimize the nutritional status. (J Community Nutrition 4(3) : 151∼158, 2002)

To investigate the effects of yellow soybean powder on serum lipid level and enzyme activities, male Sprague-Dawley(SD) rats were given hyperlipidemic diets for 6 weeks. Rats(n=8) were divided into three groups consisting the normal group(N), hyperlipidemic diets group(C) and hyperlipidemic diets and yellow soybean powder group(YSP). YSP group lowered triglyceride, total lipid, phospholpid, ester-cholesterol and free-cholesterl than control group. YSP group lowered total-cholesterol, VLDL-cholesterol and LDL-cholesterol but increased HDL-cholesterol of the serum compared to the control group. Athergenic Index(AI) and LHR(LDL-cholesterol/HDL-cholesterol ratio) of YSP group was decreased by control group (p<0.05). On the other hand, glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GTP), lactate dehydrogenase(LDHase) and alkaline phosphatase(ALP) enzymes activities were decreased by hyperlipidemic diets group (C). These results suggest that yellow soybean powder fed a lipid lowering effect in serum of rats.

The large-scale preparation method for black soybean peptide (BSP; about 70% less than 10,000 Da; highly enriched with glutamic acid, aspartic acid, and arginine) was developed, and its effect on weight reduction and lipid profiles in rats was investigated. Sprague-Dawleymale rats were assigned to four dietary groups (high-fat diets containing 0, 2, 6, and 10% BSP) and fed four weeks to examine the effects of BSP. During the experiment, food intake was measured every two days and body weight was monitored two times a week. After the supplementation of BSP, liver and adipose tissues (epididymal, retroperitoneal and perirenal adipose tissue) in the rats were weighted and the lipid profiles in serum, liver, and feces were analyzed. At the results of body weight gain, liver and epididymal adipose tissue weight, BSP groups were more decreased than HF group (0% BSP), with greater decreases at higher BSP levels. The same patterns were shown in lipid profiles of serum, as BSP was increased, triglyceride and total cholesterol concentration decreased. The serum HDL-cholesterol level was increased with increasing at BSP levels. Total cholesterol concentration of liver and feces were decreased and increased, respectively, as BSP increased. The results confirm that BSP is involved in reducing the body weight and the improvement of lipid composition in serum and liver of rats and that BSP can be applied in weight reduction in the food products industry.

The levels of $\gamma$-aminobutyric acid (GAGA) have been analyzed from pharbitis seeds by an AccQ-Tag amino acid analysis procedure. The GABA level of the pharbitis seeds was 125 nmole per gram fresh weight. To investigate the effects of pharbitis seed diets on serum and hepatic lipid levels, as well as enzyme activities of rats administered with ethanol chronically, Sprague-Dawley male rats were fed with either a AIN-76 diet (control), a control diet plus ethanol, a control plus pharbitis seed diet, or a control plus pharbitis seed diet plus ethanol for 30 days. Pharbitis seed diets decreased the serum total cholesterol, triglyceride, LDL-cholesterol, and $\gamma$-GTP levels that were increased by the chronic ethanol administration. In addition, pharbitis seed diets decreased the liver triglyceride and total lipid levels that were increased by the ethanol administration. However, ethanol metabolism was not retarded by the pharbitis seed supplemented diets. The present Endings, plus previous data showing the differences in the effects of cabbage diets having a high or a low level of GABA on the lipid levels and the enzyme activities of rats (Cha and Oh [2000] J. Korean Soc. Food Sci. Nutr. 29, 500-505), raise the possibility that GABA in plants could have a nutraceutical role in the recovery of chronic alcohol-related diseases.

The aim of this study was to analyze an association between milk consumption and serum lipid profiles in postmenopausal women in Korea. The dietary data by the Food Frequency Questionnaire were evaluated among 208 postmenopausal women who did not receive hormone therapy and their serum concentrations of triglyceride (TG), total, HDL-, and LDL-cholesterol, and alkaline phosphatase were analyzed. When the relationship between milk consumption and serum lipid profiles were analysed by linear regression, we found a negative relationship of milk consumption with ALP and a positive relationship with HDL-cholesterol. Animal calcium intake was significantly correlated with ALP and HDL-cholesterol. In addition, the serum level of HDL-cholesterol of the upper quartile (UQ) subjects who took animal calcium over 313 mg/day was significantly higher than the lower quartile (LQ) subjects who consumed milk below 101 mg/day when we compared the UQ and LQ subjects. The HDL-cholesterol level of the UQ subjects who consumed 235 ml of milk tended to be higher than the that of the LQ who consumed 53 ml. As for serum concentrations of TG, total cholesterol, and LDL-cholesterol, there was no significant difference between the UQ and LQ groups of milk consumption. Based on our study, we concluded that continual consumption of approximately one cup of milk per day was associated with low cardiovascular risks with favorable lipid profiles and ALP in postmenopausal women.

The purpose of this study was to investigate the effect of calcium intake on lipid contents and enzyme activities in rats of different ages. Lipid levels in serum and liver and GOT, CPK and LDH activities in serum were compared in rats of different ages(4 weeks and 10 months) that were fed various levels of calcium(50, 100, 200% of requirement)for 3 weeks. Body weight gain and feed efficiency ratio were significantly higher in young rats than in adults. Serum calcium level was increased by elevation of calcium intake levels were decreased. Liver phospholipid and triglyceride levels in the high-cal-terol and triglyceride levels were decreased. Liver phospholipid and triglyceride levels in the high calcium group were significantly lower than those in other groups. Serum GOT and LDH activities of adults were significantly higher in low-calcium group than those in adequate/high-calcium groups. However, serum CPK activity of adults was significantly higher in high-calcium group than that in low/adequate-calcium groups. The results of this study suggest that adequate calcium intake may have protective effects ont he alteration of lipid and enzyme activity in rats.
