For the effective utilization of tuna processing byproducts such as roes of skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacores) as a food resource, the roes of skipjack and yellowfin tuna were examined on food component characteristics and also compared to those of Alaska pollack (Theragra chalcogramma). The concentrations of heavy metal in both roe of the skipjack and yellowfin tuna were below the reported safety limits, therefore, these roes appeared to be safe as a raw material for food resource. The contents of crude protein were 21.4% in the skipjack tuna roe and 21.5% in the yellow fin tuna roe, which showed to be the major component in tuna roes. The prominent amino acids of total amino acids were aspartic acid, glutamic acid, leucine and lysine, and these amino acids were comprise to be 38.4-41.2% of total amino acid in both tuna roes. The total lipid content were 2.1 % in the skipjack tuna roe and 2.0% in the yellofin tuna roe. The major component of total lipid was found to be triglyceride in both tuna roes (skipjack tuna roe, 93.3%; yellow fin tuna roe, 92.0%), which was high in the compositions of 16:0, l8:1n-9, and 22:6n-3. The content of DHA in total lipid of the tuna roes (skipjack tuna roe, 29.9%; yellowfin tuna roe, 36.3%) were higher than that of Alaska pollack roe (18.1%). Based on the results of the proximate composition, mineral, amino acid and lipid characteristic, roes of skipjack tuna and yellowfin tuna showed potential as a raw material for food.

We have investigated the intestinal functions and hypolipidemic effects of resistant starch (RS) in rats. Experimental groups were CON (cooked starch 45% + RS 7%), RSIO (cooked starch 35% +RS 10%), RS20 (cooked starch 25%+RS20%), and RS30 (cooked starch 15%+RS 30%). The weight gains during experimental period were slightly decreased by intake of resistant starch and the weights of epididymal fat pad were lower in resistant starch intake groups than in CON, although the difference was not significant. In intestinal functions, water contents of fecal, transit time and colon cell proliferation were affected by resistant starch. Plasma total lipid and triglyceride concentrations were significantly decreased, dose-dependently, by resistant starch intake. Conclusively, it is important to intake resistant starch in order to decrease plasma lipids and to improve intestinal functions.

This study was performed to evaluate the effects of soybean powder with rich aglycone isoflavone through bio-transformation on lipid metabolism and antioxidative activites in diet induced hyperlipidemic rats. The rats were randomly divided into four groups: NO (basal diet normal group), CO (high fat diet control group), BFF10 (soybean powder with rich aglycone isoflavone 10% group), and BFF20 (soybean powder with rich aglycone isoflavone 20% group). After 7 weeks of BFF10 or BFF20 diets consumption, the concentrations in serum triglyceride, total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly decreased in the BFF10 and BFF20 diets groups compared with those in the CO group. The activities of alanine amino transferase and aspartate amino transferase were significantly decreased in the BFF10 and BFF20 than those in the CO group. Thiobarbituric acid reactive substance levels of serum were decreased in BFF10 and BFF20 groups compared to that of the CO group. The super oxide dismutase activites were increased in BFF10 and BFF20 groups compared to that of the CO group.

This study was conducted to evaluate nutrient intake, indices of anemia, serum lipids, and their correlations in 40 Korean female college students aged 21 to 25 years. Fasting blood samples were collected in October. 1997 Nutrient intake was investigated by 24-hour recall method for three days. Anthropometric measurements, blood pressure, iron status and serum lipids of the subjects were determined. The mean values for age. height, weight, BMI and blood pressure of the subjects were 22.1 years, 160.6cm, 54.4kg and 109.1/66.9mmHg, respectively. According to the body composition analysis, total body water, % body fat, lean body mass and WHR were 26.7L. 29.5%, 36.5kg and 0.8, respectively. Average daily intake of energy was 1,858.4kcal. Protein, phosphorus, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than the Korean recommended dietary allowence(RDA), whereas calcium, iron, vitamin A intakes were tower than that. Hemoglobin(Hb), hematocrit(Hct), serum iron(SI) and total iron binding capacity(TIBC) were measured and transferrin saturation (TS%) was calculated from serum. The mean values for Hb, Hct, SI, TIBC and TS were 13.6$\mu\textrm{g}$/㎗, 41.6%,97.8$\mu\textrm{g}$/㎗, 319.6$\mu\textrm{g}$/㎗ and 31.9%, respectively. The Prevalence rates of iron deficiency assessed by Hb and Hct were found to be 10% and 2.5%, respectively. However, when assessed with TIBC, the prevalence rate of iron deficiency was increased to 32.5%. The mean values for serum triglyceride(TG), total cholesterol(TC), HDL-Chol, LDL-Chol concentrations and atherogenic index(AI) were 154.7mg/㎗, 80.0mg/㎗, 47.4mg/㎗, 91.3mg/㎗ and 2.6, respectively. Correlations among indices of anemia. there were positive correlations between Hb and Hct, between SI and TS : negative correlations between TIBC and TS or SI. Correlations among serum lipids, there were positive correlations between TC and TG or LDL-cholesterol. Energy intakes were correlated positively with TIBC(p＜0.05), and vitamin C intakes negatively correlated with Hb(P＜0.05). And vitamin A intakes were negatively correlated with TG(p＜0.01). TC(p＜0.05) and LDL-Chol(p＜0.01). Hb negatively correlated with TG(P＜0.05). Body weights(p＜0.05), lean body mass(p＜0.05) and total body water(p＜0.01) werenegatively correlated with Hb. BMI and WHR correlated with TG and TC(p＜0.01). These results indicated that subjects with higher energy intake and overweight had a tendency to have iron deficiency. Increases in BMI and WHR were related to increases in serum lipids levels and decreases in TIBC. The results also showed that serum lipids were decreased when vitamin A and iron intakes were sufficient.

Objectives : This study was undertaken to verify the effects of Wolbigachul-tang1(WBCEx1) on obesity using high fat diet-induced male mice and to investigate the molecular mechanisms involved. Methods : 8-week old C57BL/6 mice were divided into 5 groups; lean control, obese control, WBCEx1, 2, 3. After mice were treated with WBCEx1(water extract), 2(30% ethanol extract), 3(water extract; Ephedra sinica Stapf., Gypsum fibrosum) for 12 weeks, body weight gain, feeding efficiency ratio, plasma lipid and glucose metabolism, the messenger RNA(mRNA) expression of peroxisome proliferator activated receptor(PPAR)$\alpha$ target genes were measured. In addition, $PPAR{\alpha}$ target gene expression was examined in liver, white adipose tissue and skeletal muscle. Results : 1. WBCEx1-treated mice had significantly lower body weight gain and feeding efficiency ratio. 2. Consistent with the effects on body weight gain, WBCEx1 decreased the weights of epididymal and retroperitoneal white adipose tissue, inguinal subcutaneous adipose tissue, and brown adipose tissue. 3. WBCEx1 significantly decreased plasma triglyceride and total cholesterol levels. 4. The size of adipocytes were significantly decreased by WBCEx1, whereas the adipocyte number per unit area was increased. Hepatic lipid accumulation was decreased by WBCEx1. 5. WBCEx1 did not affect the mRNA expression of $PPAR{\alpha}$ target genes in liver, adipose tissue, and skeletal muscle. 6. Plasma asparate aminotransferase(AST), alanine aminotransferase(ALT), blood urea nitrogen(BUN) and creatine concentrations were in the physiological range. Liver and kidney weights were significantly lower following WBCEx treatment compared with obese controls, indicating that WBCEx does not show any toxic effects on liver and kidney. Conclusions : These results suggest that WBCEx1-induced body weight reduction is associated with appetite control and mediated by a mechanism other than the activation of $PPAR{\alpha}$.

Objectives: This study was investigated the improvement effects of Pakistani Ephedra herba-containing Gangji-hwan-1, 2, 3 (Di-fatty; DF-1, 2, 3), Chinese Ephedra herba-containing Gangjihwan-4 (DF-4) and combination of DF-1 and Gamisoche-hwan (GSH) on obesity in a high fat diet-fed obese mouse model. Methods: Eight-week-old C57BL/6N mice were divided into seven groups: a normal lean group given a standard diet, an obese control group given a high fat diet, and DF-1, 2, 3, 4, and DF-1+GSH groups given a high fat diet with DF-1, 2, 3, 4 (40, 80, 160, 80 mg/kg), and DF-1+ GSH (80 mg/kg), respectively. After 8 weeks of treatment, body weight gain, feeding efficiency ratio (FER), blood lipid markers, liver histology, and fat weight and histology were examined. Results: Body weight gain was significantly decreased in DF and DF-1+GSH groups compared with control. The extent of decreases was eminent in DF-1+GSH group. FER and circulating concentration of leptin were decreased in DF and DF-1+GSH groups compared with control. Circulating concentrations of triglyceride, glucose and insulin were decreased in DF and DF-1+GSH groups compared with control. The size of adipocytes were decreased by DF and DF-1+GSH groups compared with control, whereas the adipocyte number per unit area was increased by them, suggesting that DF and DF-1+GSH groups decreased the number of large adipocytes. Conclusions: In conclusion, these results suggest that DF and DF-1+GSH groups decrease FER, plasma leptin concentration, blood anti-obesity biomarkers and fat mass, improves body weight gain. In addition, these effects were more effective in DF-1+GSH combination group than in DF-1, 2, 3, 4 groups.

The present study was conducted to evaluate the effects of various extracts of Hizikia fusiforme on the anti-obesity effects in 3T3-L1 preadipocytes. We used H. fusiforme extracts from ethanol (EEHF), dichloromethane (CFHF), ethyl acetate (EAFHF), butanol (BFHF), and water (WFHF). Treatment with these extracts significantly suppressed terminal differentiation of 3T3-L1 preadipocytes in a dose-dependent manner as confirmed by a decrease in lipid droplet content through Oil Red O staining; this effect was higher in WFHF than in other extracts. The concentrations of cellular triglyceride were also reduced in 3T3-L1 cells by exposure with these extracts, especially when compared with the controls. Treatment with 200 ${\mu}g/ml$ of WFHF and CFHF caused approximately 42.6% and 23.7% reduction, respectively. In addition, the extracts of H. fusiforme significantly reduced the expression levels of key pro-adipogenic transcription factors, including peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) and CCAAT/enhancer binding proteins ${\alpha}$ (C/$EBP{\alpha}$) and C/$EBP{\beta}$ as compared with controls. Accordingly, our data indicated that WFHF has a preeminent effect on inhibition of adipocyte differentiation among various extracts, and H. fusiforme extracts may be an ideal candidate for obesity relief.

The aim of this study was to investigate the potential effects of extracts from silkworm Bombyx mori L. fermented with Bacillus subtilis KACC 91157 at levels of 5%(v/w) and 10%(v/w) in Sprague-Dawley rats intoxicated with 1%(w/w) orotic acid (OA) for 10 days. The rats were divided into a normal group (N), a control group (C: OA), and treatment groups (SP10: OA + 10% extracts from B. mori L.; BSP5: OA + 5% extracts from B. mori L. fermented with B. subtilis KACC 91157; BSP10: OA + 10% extracts from B. mori L. fermented with B. subtilis KACC 91157). Serum activities of aspartate aminotransferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) increased following OA feeding, but the rise was slightly reduced by administration of BSP10. The total lipid, free fatty acid, phospholipid, total cholesterol, and triglyceride contents in serum were significantly lower in the OA treatment groups than in the N group. However, the contents slightly increased following the administration of BSP10. Glutathione concentrations in liver and serum were reduced in the OA-induced fatty liver, but they increased following the administration of BSP10. Hepatocytes in the OA-induced fatty liver contained numerous large droplets. However, SP10, BSP5, and BSP10 feeding prevented OA-induced lipid droplet accumulation in hepatocytes. Accordingly, extracts from silkworm powder fermented with B. subtilis could be an ideal material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.
