총 식이섬유 함량과 에너지 수준을 동일하게 조정한 보리첨가식이 및 ${\beta}-glucan$ 함량을 높인 농축획분 첨가식이가 간에서의 지질대사에 미치는 영향을 시험하였다. 체중을 고려한 간무게 결과는 콜레스테롤 투여로 증가되는 것으로 나타났으며 보리 및 ${\beta}-glucan$ 투여에 의한 차이는 없었다. Control군과 fiber-free군의 간에서는 normal(cholesterol-free)군의 간과는 달리 콜레스테롤 첨가로 인하여 심한 지질 침착이 관찰되었다. 반면 보리첨가군의 경우 동량의 콜레스테롤을 섭취하였으나 지질 침착이 거의 없거나 미약하여 normal 간과 유사한 형태였다. 간의 단위무게당 콜레스테롤과 중성지방 농도는 보리 ${\beta}-glucan$ 농축획분을 첨가한 N glucan(5%)와 W glucan(5%)군에서 각각 대조군의 50%와 60%이하 수준으로 현저하게 감소하였다. 식이섬유 함량이 10%가 되도록 찰보리 농축획분의 양을 증가시킨 W glucan(10%)군의 간 콜레스테롤 저하효과는 더욱 현저하였다. 따라서 0.5%의 콜레스테롤을 첨가하고 5%와 10%의 식이섬유를 보리로부터 공급했을 때 변으로 배설된 콜레스테롤과 중성지방을 보상하기 위한 간에서의 생합성 증가는 일어나지 않고 오히려 간의 콜레스테롤과 중성지방 함량이 현저히 낮아지고 간에 지질 침착이 일어나지 않는 것으로 나타났다.

The purpose of this study was to investigate the effect of Lycii fructus on the serum lipid in rats fed high fat diet. We compared the effects of L. fructus and L.fructus water extract both adminstered with high fat diets on rats that had previously been on high fat or standard diets. Two separate experiments were conducted for 6 weeks. respectively. In experiment I, 4 groups of rats were fed experimental diets consisting of either \circled1 6 weeks of a standard diet(control), \circled2 6 weeks of a high-fat diet(HHC), \circled3 3 weeks of a high-fat diet followed by 3 weeks of a high-fat diet containing L. fructus(HHL) or \circled4 6 weeks of a high-fat diet with L. fructus extract in place of water for the last 3 weeks (HHT). In the second set of experiments, a high-fat diet (SHC), high-fat diet containing L.fructus(SHL) or high-fat diet with L. fructus extract in place of water (SHT) were fed for 3 weeks after 3 weeks of standard diet feeding. Rats fed L. fructus diet consumed more diets than high-fat diets. THe results of experiment I showed significant decreases(p<0.05) in serum triglyceride(TB) and low density lipoprotein-cholesterol (LDL-C) levels with L. fructus feedings, but did not show andy changes in total cholesterol (TC) level. High density lipoprotein-cholesterol (HDL-C) level was increased significantly(p<0.05) with L. fructus feedings. Therefore, the ration of LDL-C to HDL-C(LDL-C/HDL-C) which is used as an atherosclerosis index was significantly (p<0.05) low, while the HDL-c/TC ration was significantly(p<0.05) high with L.fructus intake. However, no significant were found in serum cholesterols and TG levels in experimentII. The results of these experiments indicate that , regardless of the feeding from, L. fructus can be beneficial in lowering serum TG and LDL-C levels for habitual high-fat diet intakers. L.fructus also seems to be effective in elevating serum HDL-C level, theregy having beneficial effects on atherosclerosis by influencing the serum lipoprotein profile.

BACKGROUND/OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is becoming an important public health problem as metabolic syndrome and type 2 diabetes have become epidemic. In this study we investigated the protective effect of Cordyceps militaris (C. militaris) against NAFLD in an obese mouse model. MATERIALS/METHODS: Four-week-old male ob/ob mice were fed an AIN-93G diet or a diet containing 1% C. militaris water extract for 10 weeks after 1 week of adaptation. Serum glucose, insulin, free fatty acid (FFA), alanine transaminase (ALT), and proinflammatory cytokines were measured. Hepatic levels of lipids, glutathione (GSH), and lipid peroxide were determined. RESULTS: Consumption of C. militaris significantly decreased serum glucose, as well as homeostasis model assessment for insulin resistance (HOMA-IR), in ob/ob mice. In addition to lowering serum FFA levels, C. militaris also significantly decreased hepatic total lipids and triglyceride contents. Serum ALT activities and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) levels were reduced by C. militaris. Consumption of C. militaris increased hepatic GSH and reduced lipid peroxide levels. CONCLUSIONS: These results indicate that C. militaris can exert protective effects against development of NAFLD, partly by reducing inflammatory cytokines and improving hepatic antioxidant status in ob/ob mice.

Purpose: To investigate the impact of omega-3-enriched lipid emulsion (LE) on liver enzyme (aspartate transaminase [AST] and alanine aminotransferase [ALT]) and triglyceride (TG) levels of children undergoing gastrointestinal surgery. Methods: This experimental randomized controlled group pretest-posttest design study included 14 children who underwent gastrointestinal surgery due to duodenal atresia, jejunal atresia, esophageal atresia, and need for parenteral nutrition for a minimum of 3 days at RSUD Dr. Soetomo Surabaya between August 2018 and January 2019. These children were divided into two groups, those who received standard intravenous LE (medium-chain triglyceride [MCT]/long-chain triglyceride [LCT]) and those who received intravenous omega-3-enriched LE. Differences in AST, ALT, and TG levels were measured before surgery and 3 days after the administration of parenteral nutrition. Results: Liver enzyme and TG levels in each group did not differ significantly before versus 3 days after surgery. However, TG levels were significantly lower in the omega-3-enriched intravenous LE group (p=0.041) at 3 days after surgery, and statistically significant difference in changes in TG levels was noted at 3 days after surgery between MCT/LCT intravenous LE group and the omega-3-enriched intravenous LE group (p=0.008). Conclusion: The intravenous omega-3-enriched LE had a better TG-lowering effect than the MCT/LCT intravenous LE in children undergoing gastrointestinal surgery.

We are concerned about how to apply the theories of oriental medicine appropriately, which direction should it be taken, and how it should be developed. And it is believed to be essential for the government to make efforts to set a standard and laws to validate the medicinal effects and process of the assessment so that the systematic development can be encouraged, and to prepare guidance for the food development for national health improvement Ihis study was peformed to provide basic data that predict the usefulness of oriental medicinal herbs to remove the dampness through diuresis for excess syndrome obesity with oriental diet therapy cuisine(Yak-Sun). Five oriental medicininal herbs, Coix lachryma-jobi L, Atractylodes lancea DC., Ligusticum wallichii F., Angelica sinensis D., Zingiber officinale R. were collected and made into mixing extracts(OMCE). And we examined the effects of OMCE on body weight serum glucose, insulin and lipid profile improvement in rats fed high fat diets. Sprague-Dawley rae(230-250 g) were randomly divided into five groups : basal diet(normal diet control group, NCG), only high fat diet(High fat control group, HCG), high fat diet and supplemented with 25mg/100g body weight 50mg/100g body weight 75mg/100g body weight by OMCE(HLG, HMG, HHG). These experimental diets were fed for 6 weeks. The OME fed groups decreased more significantly in weight serum glucose insulin and lipids than the high fat control group did. These results imply that the OMCE can be used as a safe and clinically applicable ingredients for diet called Yaksun of excess syndrome obesity in human.

We investigated the effects of newly synthesized 4-[(butylsulfinyl)methyl]-1,2-benzenediol (SMBD) on the prevention of atherosclerosis in hypercholesterolemic rabbits. SMBD exhibited stronger inhibition of $Cu^{2+}$-induced low-density lipoprotein oxidation than that of ascorbic acid or simvastatin. Three-month-old rabbits were fed an atherogenic diet containing 0.5% cholesterol and 10% coconut oil, while other two groups were given an atherogenic diet with intravenous injection of either simvastatin or SMBD (0.33 mg/kg/day) for 4 weeks. The concentrations of plasma cholesterol and thiobarbituric acid reactive substances were significantly decreased in SMBD groups, compared to the control group. Also, aortic lipid level in the SMBD group significantly lower than that in the control group. Furthermore, compared with the control group, the SMBD group significantly inhibited the increase of aortic intimal thickness by 36% via reducing of aortic reactive oxygen species and cyclooxygenase-2 protein levels. We conclude that raised antioxidant effect of SMBD results in significant prevention against hypercholesterolemia.

홍국의 아질산염 저감화 소재로서 활용 가능성을 검토하기 위하여 bologna-type 소시지에 Monascus ruber IFO 32318로 제조한 홍국을 2% 첨가하고 $4^{\circ}C$에서 22일간 저장하면서 1, 7, 14, 22일에 시료를 채취하여 품질 특성을 조사하였다. 홍국의 첨가는 전 저장기간에 걸쳐 소시지의 색상유지에 크게 기여하였으며, 특히 소시지의 단면보다 표면 색상의 개선에 큰 효과를 나타내었다. 대조군에 홍국을 첨가한 경우 대조군에 비해 지질 과산화물 생성이 유의적으로 억제된 반면 대조군에서 아질산염과 비타민 C를 제외하고 홍국을 첨가한군은 대조군보다 과산화물의 생성이 유의적으로 많아 홍국이 비타민 C와 아질산염의 효과를 완전히 대체하지는 못하였다. 기계적 texture는 대조군에 홍국를 첨가한 군이 저장초기에 탄력성, 껌성, 경도 및 응집성에서 높은 값을 나타내었으나 저장 14일 이후에는 모든 군에서 차이가 나타나지 않아 장기간 저장하는 경우 홍국의 첨가가 소시지 texture에 영향을 미치지 않는 것으로 나타났다. 홍국첨가에 의한 미생물 증식 억제효과는 뚜렷이 나타나지 않았다. 관능적으로도 홍국을 첨가한 경우 소시지 외관의 색상을 개선시켰으며 유의적이지는 않으나 산패취 도한 저하되는 경향을 나타내었고, 조직감 및 맛과 전반적인 기호도에서 대조군과 유의적인 차이를 나타내지 않아 홍국을 육가공품 제조에 적절히 활용하므로써 아질산염을 부분적으로나마 대체할 수 있는 소재로 활용가능할 것으로 기대된다.

This study was designed to evaluate impact of kinds of dietary grain and dietary lipid level on the glucose metabolism and antithrombogenic capacity in obesity induced rats. Total of 80 Sprague-Dawley male rats were raised for one month with control diet containing $50\%$ (w/w) well-milled rice powder and $20\%$(w/w) of dietary lipids. The rats were blocked into 8 groups and raised for two months with diets containing well-milled rice, brown rice, black rice, or glutinous barley powder and 8 or $20\%$(w/w) of dietary lipids. The contents of total dietary fiber in experimental grains were in following order; glutinous barley > black rice > brown rice > well-milled rice. Weekly food intake were lower in glutinous barley group among all experimental groups. Body weight gain was high in high level of fat groups ($50\%$w/w) than medium level of fat groups ($8\%$ w/w). Plasma glucose concentration was not different significantly in each groups. But brown rice group was a little lower than others. Plasma insulin concentration was lower in black rice and glutinous barley group than rice group. Plasma glucagon concentration did not differ significantly among all experimental groups. Hexokinase activities in skeletal muscle are different significantly according to level of dietary fat and grain variety factors. Brown rice group was significantly highest among all experimental groups in hexokinase activity. Plasma $TXB_2$ concentrations in black rice and glutinous barley groups were lower as compared to rice and brown rice groups. Plasma 6-keto-$PGF_{1\alpha}$ concentrations in glutinous barley group was higher as compared to others. In conclusion brown rice has a little lowering effect glucose concentration. Black rice and glutinous barley intakes enhance antithromboenic capacity. It is suggested that the intakes of mixed gains are recommend.

The current study examined the effect of quercetin supplements on the lipid-lowering and antioxidant metabolism in ethanol-fed rats. The control $group(E_8)$ received ethanol only diet for 8 wks, whereas the other group$(E_8Q_4)$ received a diet including quercetin supplementation(0.05% wt/wt) for 4 wks while on the ethanol diet for 8wks. The hepatic alcohol dehydrogenase activity was significantly higher in the $E_8Q_4$ group than in the $E_8$ group. Supplementation with quercetin significantly elevated the HDL- cholesterol concentration, the HDL-C/total-C ratio, and lowered the atherogenic index(AI) compared to the $E_8$ group. The hepatic triglyceride and cholesterol contents were significantly lowered by the quercetin supplement compared to those of the control group. The hepatic HMG-CoA reductase and ACAT activities of the $E_8Q_4$ group were significantly lower than those of the $E_8$ group. The overall potential for antioxidant defense was significantly enhanced by the quercetin supplement, as indicated by a decrease in plasma and hepatic TBARS levels. The hepatic GSH-Px and G6PD activities were significantly higher in the $E_8Q_4$ group compared to the $E_8$ group. The current results suggest that dietary quercetin leads to the inhibition of HMG-CoA reductase and ACAT, which in turn lowers cholesterol levels and normalizes antioxidant enzyme activities.

Objective: Reduced crude protein (CP) diets offer potential benefits such as optimized feed efficiency, reduced expenses, and lower environmental impact. The objective of this study was to evaluate black soldier fly larvae (BSFL) meal on a low-protein diet for duck performance, blood biochemical, intestinal morphology, gastrointestinal development, and litter. Methods: The experiment was conducted for 42 days. A total of 210-day-old male hybrid ducklings (5 replicate pens, 7 ducks per pen) were randomly assigned to 6 dietary treatments (3×2 factorial arrangements) in randomized design. The factors were CP level (18%, 16%, 14%) and protein source feed soybean meals (SBM), black soldier fly larvae meals (BSFLM). Results: Reduced dietary CP levels significantly decreased growth performance, feed intake, the percentage of nitrogen, pH (p<0.05), and tended to suppress ammonia in litter (p = 0.088); increased lipid concentration; and enhanced relative weight of gastrointestinal tracts (p<0.05). In addition, dietary BSFL as a source of protein feed significantly increased lipid concentration and impacted lowering villus height and crypt depth on jejunum (p<0.05). Conclusion: In conclusion, the use of BSFLM in a low-protein diet was found to have a detrimental effect on growth performance. However, the reduction of 2% CP levels in SBM did not have a significant impact on growth performance but decreased nitrogen and ammonia concentrations.
