Objectives This study was designed to evaluate the efficacy of Seungyangjeseup-tang on obesity by using 3T3-L1 cells and high fat diet mice. Methods In vitro, Seungyangjeseup-tang extract (SYJST) (10, 50, 100, 200, 400, $800{\mu}g/mL$) ware added in 3T3-L1 cells. SYJST cytotoxicity was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assasy. Adipocyte differentiation was measured by Oil Red-O staining. In vivo, the experimental animals were divided into five groups: normal diet-fed normal group (N), high-fat diet (HFD)-fed control group (Con), HFD+SYJST 100 mg/kg group (SY100), HFD+SYJST 200 mg/kg group (SY200), and HFD+olistat 60 mg/kg as a positive drug control group (Orli). Markers of obesity, such as body weight, liver weight, food intake, serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), liver tissue TC, TG and fecal TC, TG were measured. Results In vitro, cytotoxicity was not significant compared with the control group. 3T3-L1 cell's differentiation was significantly decreased in Oil Red-O staining. In vivo, compared with controls, mice treated with SYJST demonstrate lower body and liver weight, and reduced food intake. In addition, SYJST increased TC, TG in the serum but not significance. And SYJST showed decreasing tendency TC, TG in the liver tissue. Furthermore, SYJST increased TC, TG in the facal but not significance. Conclusions Based on the results above, Seungyangjeseup-tang may reduce adipocyte differentiation, body fat, food intake, liver weight in obesity. This suggests that Seungyangjeseup-tang may be clinically useful in obesity treatment.

This study was performed to investigate the effect of 12 weeks red-ginseng intaking on MDA(malondialdehyde) produced during aerobic exercise in the young and elderly women. Sixteen volunteers agreed to participate and were placed in 2 groups: in the young(20-25 yrs), red-ginseng intake group(n=8), in the elderly(60-69 yrs), red-ginseng intaking group(n=8). The subjects who joined this study were asked to take 2.7g of red-ginseng powder capsule per day before the meal for 12 weeks(3 times/day). MDA(from blood samples) were collected at rest, just after the submaximal exercise, and 30 minutes after the exercise(cycle ergometer riding) at the beginning and the end of the 12-weeks program. After 12 weeks of red-ginseng intaking, young and elderly groups showed the decreased MDA significantly at rest(41.57%, 28.59%), just after the exercise(45.96%, 40.74%). and 30 minutes after the exercise(37.37%, 32.68%). These results indicate that red-ginseng intaking, as an antioxidant, may be useful for removing MDA produced during aerobic exercise in the elderly.

The aim of this study was to assess dietary fiber intake and the relationship between dietary fiber intake and nutrient intakes of elementary school students. Food consumption of 200 elementary school students (100 boys, 100 girls) in the 6th grade in Gimhae was assessed by 2-day estimated food records. Nutrient intakes were calculated using CAN-pro and total dietary fiber (TDF) intake using the TDF tables of the common Korean foods. The mean height and weight of the boys were 147.7 cm and 42.1 kg. The mean height and weight of the girls were 149.1 cm and 41.1 kg. The mean body mass index (BMI) of the boys (19.3 $kg/m^2$) was significantly higher than that of the girls (18.4 $kg/m^2$, p < 0.05). Average daily intake of energy of the boys and girls was 1733 and 1778 kcal, respectively. Intakes of protein, P, and niacin of the boys and girls exceeded $110\%$ of current RDA. Intakes of Fe, vitamin $B_1$ and vitamin $B_2$ of the boys were similar to RDA. Intake of vitamin $B_1$ exceeded $110\%$ of current RDA and intakes of Fe and vitamin A were similar to RDA among the girls. Ca intake of the boys and girls was $74.2\%$ and $60.1\%$ of RDA, respectively. Vitamin C intake of the boys and girls were $63.6\%$ and $71.7\%$ of RDA, respectively. Intakes of fat, Ca, P, and vitamin $B_2$ of the boys were significantly higher than the girls. Intakes of Fe and vitamin A of the boys were significantly lower than the girls. Average daily intakes of TDF of the boys and girls were 11.2 g and 11.1 g, respectively. TDF intake of the children at the 6th grade of elementary school was about $70\%$ of 'age (yr) + 5 g', a recommended level for American children. Major food groups to supply dietary fiber were vegetables, grains, and seasonings among the boys and girls. Major sources of dietary fiber were Kimchi, rice, and red pepper powder which supplied $17.85\%$. $15.71\%$, and $5.18\%$ of TDF among the boys and $18.02\%$, $16.22\%$, and $6.58\%$ among the girls. Daily fiber intake showed significant positive correlations with intakes of grains, vegetables, fruits, legumes, and seasonings among the boys and girls. Daily fiber intake showed significant positive correlations with intakes of energy, carbohydrates, protein, lipids, Ca, P, vitamin A, vitamin $B_1$ vitamin $B_2$, niacin, and vitamin C among both the boys and girls. From the results of this study we could conclude that it is recommended to increase dietary fiber intake in elementary school students at upper level.

The purpose of this study is to compare the clearance rate (CR) and intake rate (IR) of juvenile purple clam, Saxidomus purpuratus when feeding on different unialgal diet of red tide dinoflagellates (RTDs), and to know what is the most important cell characteristic of RTDs to cause the differences in feeding parameters. Experiments were performed to measure the CR and IR of juvenile S. purpuratus as a function of algal concentration when food was either the standard food, Isochrysis galbana or one of 9 RTDs. Patterns of CR with increasing algal concentration were similar among different RTDs. The highest $C_{max}$ was observed when S. purpuratus was feeding on A. affine, while the lowest on C. polykrikoides. The patterns of IR with increasing algal concentration were also similar among different RTDs. However, there were great differences in the maximum value of IR ($I_{max}$) among different RTDs. The highest $I_{max}$ was observed when S. purpuratus was feeding on A. carterae, while the lowest on G. catenatum. Some RTDs similar in size showed different $C_{max}$. Other RTDs different in size showed similar $I_{max}$. Life form of each RTD affected significantly the $I_{max}$, which was higher for single-celled RTDs than chain-forming RTDs. There were no significant differences in feeding parameters between toxic and nontoxic RTDs. Moreover, a toxic dinoflagellate, A. carterae recorded the highest $I_{max}$ among RTDs. The most important characteristic of RTD as a factor affecting the feeding rate of S. purpuratus was life form, not size or toxicity of RTD species.

Ginseng has been used as a traditional medicine for treatment of many diseases and for general health maintenance in people of all ages. Ginseng is also used to ameliorate menopausal systems. We investigated the estrogenic activity of Korean red ginseng (KRG) in a transient transfection system, using estrogen receptor (ER) and estrogen-responsive luciferase plasmids in MCF-7 cells. The extract activated both ER${\alpha}$ and ER${\beta}$. KRG modulated the mRNA levels of estrogen-responsive genes such as pS2 and ESR1 and decreased the protein level of ER${\alpha}$. In order to examine in vivo estrogenic activity of KRG, sixteen female Sprague-Dawley rats separated into four groups were studied for nine weeks: non-ovariectomized (OVX) rats treated with olive oil, OVX rats treated with olive oil, OVX rats treated with 17-${\beta}$-estradiol (E2) in olive oil, and OVX rats treated with KRG extract in olive oil. The experiments were repeated for three times and the data of twelve rats were combined. Body weight of OVX rats was greater than that of sham-operated control rats and was decreased by E2 treatment. Uterine weight increased after E2 treatment compared to OVX rats. However, no difference in body or uterine weight was observed with KRG intake. KRG induced reductions in total cholesterol, low density lipoprotein cholesterol/total cholesterol, high density lipoprotein cholesterol/total cholesterol, and low density lipoprotein cholesterol/high density lipoprotein cholesterol, but not to the same degree as did E2 intake. These results show that KRG does contain estrogenic activity as manifested by in vitro study but the activity is not strong enough to elicit physiological responses.

We investigated the proper feeding frequency and satiation rate for the growth of red- and white-colored carp fingerlings in a feeding experiment. Triplicate groups of fish averaging 6.3 g were fed diets at four feeding frequencies (1, 2, 3, or 4 meals a day) and two satiation rates (satiation and 80% satiation) for 6 weeks. The survival of the fish was not affected by either the feeding frequency or the satiation rate. The weight gain, feed efficiency, and protein efficiency ratio of fish were affected by the feeding frequency and satiation rate, and increased significantly with both. The feed efficiency and protein efficiency ratio with satiation feeding of fish fed four meals a day did not differ from those of fish fed three meals a day. The daily feed intake was affected by the feeding frequency and satiation rate. The moisture, crude lipid, and ash contents of whole body were affected by the feeding frequency. Moisture and crude lipid contents were affected by feeding satiation. Based on these results, we conclude that the proper feeding frequency and satiation rate for the optimum growth of red- and white-colored carp fingerlings is four meals a day with satiation feeding.

Growth of fish is controlled by various environmental factors, including water temperature (WT). WT is also a major factor that affects the eating behavior of fish. In this study, we studied the relationship between WT and expression profiles of factors involved in appetite regulation and digestion in red spotted grouper. Fish were divided into three groups with 30 fish per group and reared for 2 weeks in a recirculating system at three different WT (natural WT, 20 ℃, and 25 ℃). After 2 weeks, they were sacrificed immediately after food intake (+ 0 h), 3 h after (+ 3 h), 6 h after (+ 6 h), and 3 h before being fed the next day (- 3 h). Fish samples were obtained for analysis of mRNA expression levels of cholecystokinin (CCK), leptin A (LepA), leptin B (LepB), and neuropeptide Y (NPY) in the brain, liver, and intestine. Expression of CCK and NPY mRNA was significantly higher at 25 ℃ compared to that at natural WT and 20 ℃, but no difference was observed for leptin. This suggests that the red spotted grouper shows characteristics typical of subtropical fish and has higher levels of feeding and digestion when reared at 25 ℃ water temperature condition.

This study was undertaken to investigate the knowledge and the use of Korea traditional basic side dishes, Jangachies, by housewives. Among the 58 kinds Jangachies, the most well-known Jangachies (above 80% of subjects) turned out to be Perilla leaf, Red pepper leaf, Garlic, Young stem of garlic, Green red leaf, Cucumber and dried Radish Jangachi in the order. In cooking experience of Jangachi, 40% of subjects in Perilla leaf, 28.0% in Green red pepper, 24.8% in Garlic and 24.1% in Red pepper leaf Jangachi have cooked frequently. The proportion of subjests who has bought the marketed Jangachi products were 51.6%. Major problem of that products was pointed out for a sanitary condition, high price and poor taste. If marketed Jangachies were improved over the aspects, the proportion of subjects who would buy the products was 76.2%. The frequency of Jangachi intake was very low on a average due to too salty taste and the difficulty in preparation. The older in age, the more in interest level for Jangachi (p<0.05). 39.6% of subject have had preparation ability of Jangachies. With increasing age (p<0.01), decreasing education level (p<0.01) and those who live in rural area (p<0.05), preparation ability of Jangachi tended to be higher.

A nutrition survey of 128 perschool children, 4 to 6 years old, in the Saemaul Youlgok day care center, located in one uplane, overpolulated, poor area of the city of Seoul, sponsered by the Korean Red Cross Society, was undertaken between August 21 and 31, 1984, to investigate dietary and nutritional status. RESULTS: Mean values of height, weight, arm circumference, girth of chest, and head circumference ranged from 95 to 100% of KIST mean. However, 4.8~14.2% of the subjects were assessed as undernourished in terms of 'weight for height'. Mean hemoglobin vcalue was 12.1±0.7gm%, and mean hematocrit value was 38.5±2.2%; 4.1% of the subjects were proven to be anemic according to the criterion of hemoglobin established by the ICNND. Mean urinary urea nitrogen/creatinine ratio was 11.4±3.8. Regarding mean energy and nutrient intake, the following percentages had intakes below two-thirds of the 1985 RDAs: 28.8% of children, for protein; 48.8% of children, for iron; and 28.8% of children, for calcium. About 25% of children had vitamin A intake below one-third of the recommended allowance. Carbohydrate provided 71% of total energy intake; protein accounted for 13%; fat provided 16%. Energy intake was divided among breakfast, lunch, dinner and snacks in a percentage ration of 19:26:21:34. The lunch, and snacks which were served at the day care center provided 36.5~79.1% of daily energy and nutrient intake. The survey clarified that the day care feding largely supplemented the inadequate dietary intakes of these young children at home. According to factor analysis of energy and nutrient intake, there were two factor groups : the first factor group, for energy, protein, carbohydrate, iron and niacin, mainly provided by grains; and the second factor group, for calcium, vitamin A, thamin, riboflavin and ascorbic acid, provided by vegetables, fruits, milk and milk products. The survey also revealed significant correlation coefficients between family factors such as family income, educational level of parents, and number of children; and dietary or nutritional status of the subjects.

Underreporting patterns by the level of obesity have not been fully assessed yet. The purpose of this study was to examine the differential underreporting patterns on cardiovascular risk factor, macronutrient, and food group intakes by the level of Body Mass Index (BMI). We analyzed cross-sectional baseline nutritional survey data from the population-based longitudinal study, the Healthy Women Study (HWS) cohort. Study subjects included 538 healthy premenopausal women participating in the HWS. Nutrient and food group intakes were assessed by the one-day 24-hour dietary recall and a semi-quantitative food frequency questionnaire, respectively. The ratio of reported energy intake (EI) to estimated basal metabolic rate (BMR) was used as a measure of relative energy reporting status and categorized into tertiles. Overweight group ($BMI{\geq}25kg/m^2$) had a higher ratio of EI to BMR (EI/BMR) than normal weight group ($BMI<25kg/m^2$). Normal weight and overweight groups showed similar patterns in cardiovascular risk factors, nutrient intake, and food group intake by the EI/BMR. Fat and saturated fat intakes as a nutrient density were positively associated with the EI/BMR. Proportion of women who reported higher consumption (${\geq}4\;times/wk$) of sugar/candy, cream and red meat groups was greater in higher tertiles of the EI/BMR in both BMI groups. Our findings suggest similar patterns of underreporting of cardiovascular risk factors, and macronutrient and food group intakes in both normal and overweight women.
