This study is to make a comparison between the one liquid emulsion with and without fish oil containing higher omega-3 fatty acid in parenteral nutrition (PN) of newborns. Serum chemistry and clinical complications from Medical Records of 76 newborns who had received PN with either SMOFlipidⓇ or ClinOleicⓇ for at least 7 days in NICU at Chosun Univeristy Hospital from January 2011 to December 2014 were reviewed retrospectively. Serum chemistry revealed no significant difference between the two groups except for total bilirubin (TB), glucose, blood urea nitrate (BUN), creatine (Cr), and cholesterol, but they even were not clinically significant as their values were within almost normal range. In terms of the difference in clinical complications, the incidence of cholestasis was higher in newborns given ClinOleicⓇ. However, there was no statistically significance. In this study, no significant difference between ClinOleicⓇ and SMOFlipidⓇ in their clinical efficacy was proven. But, considering the advantage of omega-3 fatty acid in reduction of cholestasis and infection risk, more studies may be needed using lipid emulsions containing higher content of fish oil with high omega-3 fatty acid, and they may be better if done with larger groups.

Menopause is characterized by a decrease in estrogen production by the ovaries. Furthermore, the risk of developing chronic diseases including cardiovascular disease, obesity, and diabetes increases in menopausal women. In this study, we evaluated the ability of Caragana sinica (CS) to affect lipid and glucose metabolism in an ovariectomized Sprague-Dawley rat model of induced menopause. The animals were divwided randomly into three groups: sham-operated rats (SHAM), ovariectomized rats (OVX), and ovariectomized rats treated with 1% water extract of CS (OVX-CS). The OVX-CS treated mice showed a significant decrease in body weight, adipose tissue, triglyceride, and total cholesterol. Improved lipid and glucose profiles were also observed, and were attributed to suppression of hepatic lipogenesis and adipokine production and regulation of glucose-regulating enzyme activity. Therefore, these findings indicate a potential use for CS as a functional food for menopause-induced hyperlipidemia and hyperglycemia.

We investigated the effects of Acorus gramineus water extract on the blood lipid levels in high fat diet-fed obese male mice. We divided thirty-five C57BL/6 mice into 5 groups: normal group, control group, and groups treated with Acorus gramineus water extract at concentrations of 20, 100, and 500 ㎎/㎏. We inoculated Acorus gramineus water extract per orally once a day for 6 weeks respectively. The results revealed that Acorus gramineus water extracts had positive effects on the total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol levels.

방사선에 의해서 유도된 간 손상에 대한 백삼과 발효인삼추출물의 보호효과를 비교 연구하였다. ICR계 생쥐에게 코발트-60 감마선의 5Gy조사 7일 전부터 백삼과 발효인삼추출물(150㎎/㎏/day)을 각각 투여하였 다. 대조군은 생리적 식염수를 투여하고 방사선조사군은 생리적 식염수를 투여하면서 5Gy를 조사하였다. 그리고 각각의 실험군에서 간조직의 H2O2, catalase, MDA를 측정하였다. 그 결과 방사선조사군과 보다 백 삼과 발효인삼추출물 투여군에서 catalase함량이 유의성 있게 증가하여 간의 보호효과가 있었으며 H2O2와 MDA함량도 유의성 있게 감소하였다. 백삼과 발효인삼이 간 조직에 대한 방사선조사로 부터 매우 우수한 방호제라고 할 수가 있다.

This study was conducted to evaluate the cytotoxicity and α-amylase, α-glucosidase, pancreatic lipase inhibition in vitro by different solvent fractions from the roots of Codonopsis lanceolata. The values of IC50 against Calu-6 cell showed a high effect in n-hexane fraction (10.13 μg/mL) whereas DW fraction exhibited the weakest inhibition on cell viability, having an IC50 value of over 1,000 μg/mL. The values of IC50 against HCT-116 cell showed the highest activity in n-BuOH fraction (102.01 μg/mL), followed by n-hexane fraction (145.85 μg/mL), methylene chloride fraction (332.02 μg/mL), ethyl acetate fraction (462.93 μg/mL) and DW fracion (>1,000 μg/mL). α-Amylase inhibitory activity in methylene chloride fraction and ethyl acetate fraction was found to have a higher inhibitory effect with 24.5% and 25.6% than the other fractions. The highest α-glucosidase inhibitory activity was observed from the ethyl acetate fraction extract, while the extract of DW fraction showed the lowest level of inhibitory activity at given experiment concentration. The pancreatic lipase inhibitory activity of C. lanceolata was found to have a higher the effect in ethyl acetate fraction. Inhibition of lipase activity of the ethyl acetate fraction and n-hexane fraction showed a relatively high, while the extract of DW fraction showed the lowest level at given experiment concentration. These results suggested that the roots of C. lanceolata may assist in the potential biological activity on carbohydrate, lipid Inhibitory activity and anticancer activity.

본 연구에서는 연화 열수 및 에탄올 추출물의 3T3-L1 지방세포 분화 및 ROS생성 저감효과를 구명하기 위하여 3T3-L1 전지방세포 분화과정 중 연화 열수 및 에탄올 추출 물에 의한 지방축적과 ROS 생성을 관찰하였다. 연화 열수 및 에탄올 추출물은 XTT assay에서 100, 200 및 400 μg/mL 농도에서 세포 독성을 보이지 않았다. 지방세포 분화 중 세포 내 지방축적 및 ROS 생성량을 비교한 결과, 연화 열수 및 에탄올 추출물을 처리한 지방세포의 경우 지방축적량과 ROS 생성량 모두 유의적으로 억제되는 것으로 나타났다. 특히 연화 열수 및 에탄올 추출물을 처리함으로써 지방세포 분화와 관련된 전사인자인 PPARγ, C/EBPα 및 aP mRNA의 발현을 유의적으로 감소시켰으며, ROS의 생성과 관련이 있는 주요 유전자인 NOX4 및 catalase의 유전자발현 또한 유의적으로 감소하였다. 이 결과를 통해 연화 열수 및 에탄 올 추출물이 3T3-L1 지방세포 내 중성지방의 축적 억제 효과와 더불어 ROS 생성 억제에 효과적으로 작용함을 확인 하였다. 따라서 연화 열수 및 에탄올 추출물은 비만과 같은 대사증후군 관련 질환의 개선을 위한 천연물 기능성 소재로 의 활용이 기대된다.

The ovariectomized Sprague-Dawley female rats were randomly assigned to Sham-Control, OVX-Control, OVX-Superjami (extract) groups. The results showed that the activity of glucokinase to keep the blood sugar constant is increased by increasing insulin secretion from pancreatic β- cells and the homeostatic regulation of glucose. Meanwhile the glyconeogenesis which is involved in the actions of the enzymes glucose-6-phosphatase and phosphoenolpyruvate carboxykinase showed that the glucose level is decreased. It was confirmed that these enzymes regulate the carbohydrate metabolism. On the other hand, results of the measurement of the lipid metabolism in the fat tissue and liver tissue, effect of β-oxidation enzymes and carnitine palmitoyl transferase which is involved in fatty acid oxidation for energy generation is increased. Moreover, the activity of fatty acid synthase, glucose-6-phosphate dehydrogenase and malic enzyme have been reduced, therefore, it was confirmed that these enzymes regulate the lipid metabolism.

본 연구에서는 오디 농축액을 우리나라 전통한과인 약과에 첨가하여 약과의 저장 중 품질 특성에 미치는 영향에 대하여 분석하였다. 약과의 수분함량은 대조군에 비하여, 오디 농축액 3% 첨가 약과가 높은 수분함량을 나타내었다. 저장 기간별 약과의 수분함량은 모든 군에서 2주 동안 급격한 수분함량의 감소를 나타내었고, 2주와 3주의 수분함량 변화는 유의적 차이를 나타내지 않았다(p<0.05). 오디 농축액을 첨가한 약과의 색도는 0주차의 오디 약과에서는 명도(L)는 대조군에 비해 오디 농축액의 첨가량이 많아질수록 낮아지는 경향을 보였고, 적색도(a)는 대조군 5.88, 오디 농축액 3% 첨가군은 6.69로 오디 농축액을 첨가할수록 높게 나타났다. 또한 황색도(b)는 18.32~11.51로 오디 농축액 첨가량이 높아질수록 낮아지는 경향을 보였다. 명도(L)는 저장기간이 지남에 따라 대조군이 58.56에서 46.45로, 오디 농축액 3% 첨가군은 43.82에서 35.92로 낮아졌고, 적색도(a)와 황색도(b) 모두 3주가 경과하면서 높아지는 것을 볼 수 있었다. 지질산패정도를 알아보는 실험중 산가는 시간이 경과함에 따라 유의적 차이가 나타나(p<0.05) 3주차 오디 농축액을 첨가한 약과는 1.65~1.91의 산가를 나타내었고, 대조군은 1.97로 오디 농축액 첨가군이 대조군보다 산가보다 더 낮게 나타났다. 과산화물가는 0주차에는 시료간의 유의적인 차이가 나타나지 않다가 3주차에는 대조군 63.80 meq/kg, 오디 농축액 1% 첨가군 58.46 meq/kg, 2% 첨가군 55.00 meq/kg, 3% 첨가군 52.54 meq/kg로 대조군의 과산화물가가 오디 농축액 첨가군에 비해 높은 경향을 나타내었다. 0주차 TBA가는 11.25~13.11로 오디 농축액을 첨가할수록 낮은 값을 나타내었고, 3주가 경과한 후 TBA측정 결과 대조군이 가장 높은 TBA가를 나타내었으며 오디 농축액 3% 첨가군이 가장 낮게 측정되었다. DPPH 라디칼소거능은 오디 농축액의 첨가량이 많아질수록 증가하는 경향을 나타내었고, 저장 기간 동안 모든 군의 DPPH라디칼소거능은 감소하였으나 오디 농축액 첨가군이 대조군에 비해 낮은 IC50값을 유지하였다. 실험의 결과들로부터 오디농축액의 첨가량이 증가할수록 항산화성이 높아지고, 지질산패를 억제되는 것을 확인하였다. 이는 항산화성의 증가로 인해 오디 농축액을 넣은 약과가 넣지 않은 약과보다 지질산패가 억제되는 것으로 사료되며, 약과 제조시 오디농축액을 첨가하면 저장성이 증대된 약과를 생산할 수 있을 것으로 기대된다.

This study was designed in order to determine the influences of haw (Crataegus pinnatifida BUNGE) on the lipid metabolism syndrome. Sprague Dawley rats, 7 weeks old, were given four different types of diets for 5 weeks: ND group (noncholesterolemic diet), HE group (non cholesterolemic diet+haw extract), CD group (cholesterolemic diet), CH group (cholesterolemic diet+haw extract). Concentrations of LDL-cholesterol, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose were remarkably higher in the CD group than the other groups. But by treatment of haw extract group with cholesterolemic diet (CH group) were significantly decreased compared with CD group. Cholesteryl ester ratio was no difference between CD group and CH group. These results indicate that Crataegus pinnatifida BUNGE would be effective in lipid metabolism syndrome.

Onion (Allium cepa L.) is one of the richest sources of flavonoids in human diet. Onion peel contains over 20times more quercetin than onion flesh. In this study, we studied the effects of onion peel water extract (OPE) on the bloodlipid profiles in mice. The onion peel extracts was extracted with hot water. The experimental groups were divided with 3groups (n=6) of ICR male mice: normal diet+distilled water (NC), high-fat diet+distilled water (HF), high-fatdiet+onion peel water extract 20㎎/㎏ (OPE-20). The oral administration was conducted daily. The experimental periodwas 7 weeks. Onion peel water extract showed higher concentration of polyphenol gallic acid and anti-oxidant trolox equiv-alent than the ethanol extract. The body weight gain and food efficiency ratio was significantly lower in the OPE-20 group ascompared with HF group (p<0.05). The epididymal fat and retroperitoneal fat showed significantly lower weights and sizesin the OPE-20 group as compared with HF group (p<0.05). The serum levels of total cholesterol, LDL cholesterol and trig-lyceride were significantly lower in the OPE-20 group as compared with HF group (p<0.05). The OPE-20 group showedhigher HDL cholesterol concentration than HF group (p<0.05). Atherogenic index was ignificantly lower in as comparedwith HF group (p<0.05). The serum levels of glucose, GOT and GPT were significantly lower in the OPE-20 group as com-pared with HF group (p<0.05). In these results, we suggests that onion peel water extracts supplementation can reduces theserum lipid components and improves the lipid metabolism in hyperlipidemic mice induced with a high-fat diet.

Western blot을 통해 지방관련 단백질 발현양상을 본 결과 지방분해에 관여하는 PPAR α의 경우 섬더덕 추출물을 급여함으로써 발현양이 증가하였으며, 지방생성 관련 단백질인 SREBP-1, FAS, ACC의 경우 고지방식이군과 비교 시, 섬더덕 추출물을 공급한 군에서 억제되었다. 이상의 결과로 섬더덕 추출물의 섭취는 체중 감소와 더불어 혈장 지질수준 개선에도 도움을 줄 수 있음을 제시하였다.

The aims of this study were to investigate and confirm the occurrence and distribution patterns of blood lipid lower agents (BLLAs) in Nakdong river basin (mainstream and its tributaries). 4 (atorvastatin, lovastatin, mevastatin and simvastatin) out of 5 statins and 2 (clofibric acid and zemfibrozil) out of 3 fibrates were detected in 29 sampling sites and simvastatin (>50%) was predominant compound followed by atorvastatin, lovastatin and clofibric acid. The total concentration levels of BLLAs on April, August and November 2009 in surface water samples ranged from ND∼25.7 ng/L, ND∼18.8 and ND to 38.8 ng/L, respectively. The highest concentration level of BLLAs in the mainstream and tributaries in Nakdong river were Goryeong and Jincheon-cheon, respectively. The sewage treatment plants (STPs) along the river affect the BLLAs levels in river and the BLLAs levels decreased with downstream because of dilution effects.

The objective of this study was determined to evaluate α-amylase, α-glucosidase, pancreatic lipase inhibition in vitro and DPPH radical scavenging activity of the several Korean resources plants. The α-amylase inhibitory activity of Salicornia herbacea, Erythronium japonicum (flower) and Phragmites communis (root) in water extract showed relatively high 62.8%, 66.5% and 69.3%, respectively. The α-amylase inhibitory activity of Citrus junos (pericarp) and Cornus officinalis in methanol extract was found to have an effect with 32.8% in Citrus junos (pericarp) and 60.9% in Cornus officinalis. Corylopsis coreana in both water and methanol extract had the highest α-glucosidase inhibitory activity of 81.7% and 89.5%, while the extract of Portulaca oleracea, Ficus carica and Citrus junos was not measured α-glucosidase inhibitory activity at given experiment concentration. Depending on the extraction solvent and the plant species, it was observed that there was a significant difference in α-glucosidase inhibitory activity. The pancreatic lipase inhibitory activity showed relatively higher in the methanol extract than water extract except pericarp of Citrus junos. The DPPH radical scavenging activity of selected plants was much difference between measured plant species, and showed that the increase was proportional to the concentration. These results suggested that selected plants had the potent biological activity on carbohydrate, lipid Inhibitory activity and antioxidant activity, therefore these plant resources could be a good materials to develop medicinal preparations, nutraceuticals or health functional foods for diabetes or obesity.

This study is a basic study on the development of functional substances involved in obesity prevention, lipid metabolism, and immune regulation. Male Sprague-Dawley rats were fed a high-fat diet for 10 weeks. Allium monanthum extracts (AME) were administered orally to obesity-induced rats, and their lipid-lowering, antioxidative and various types of biological effects related to the immune system were examined. Blood free fatty acid and triglyceride concentrations decreased as the dose of AME increased. Total cholesterol and LDL cholesterol concentrations in the blood decreased as the dose of AME increased. The total cholesterol concentrations in the liver of the AME-treated groups were lower than the control group. The thiobarbituric acid reactive concentrations were lower in the plasma and liver of all AME-treated groups than the control group. Plasma AST and ALT activities did not show any significant differences among the treatment groups. IL-1β and IL-6 concentrations in the liver tended to decrease as the dose of AME increased. TNF-α and IL-10 concentrations did now show any significant differences compared to the control group. Lower expression levels of TNF-α, Apo-B and Apo-E genes were found in the AME-treated groups. Taken together, these results indicate that AME may show positive effects in lipid lowering, antioxidation and anti-inflammation.

The effects of gamma irradiation at medium dose levels on commercial starches (corn starch/CS, sweet potatostarch/SS, and potato starch/PS) were investigated in terms of its color and lipid oxidation. The CS, SS, and PS samples were irradiated at 0, 1.5, 3, 4.5 and 6 kGy by a Co-60 gamma irradiator and used for measuring Hunter's colors and TBA value. Irradiation doses applied did not cause apparent changes in Hunter color parameters between the control and irradiated groups. But, the decrease in lightness (L value) for CS and the increase in both redness (a value) for SS and yellowness (b value) for PS were observed, respectively, thereby resulting in slight increase in overall color difference (ΔE) upon irradiation. Browning intensity observed with the naked eye for gelatinized starches by irradiation doses was also gradually increased along with irradiation dose, which was more remarkable in SS. The thiobarbituric acid (TBA) values of samples showed a dose-dependant increase with ≥ 0.9964 of R2 (p<0.05).
