  • 치커리 물추출물은 실험동물의 지질대사에 영향을 미치는 것으로 알려져 있으나, 이러한 영향에 대한 대사가 작은 명확하게 밝혀져 있지 않다. \ulcorner음처리한 치커리(roasted-chicory)또는 볶음처리하지 않은 치커리(unroasted-chicory)로부터 물추출한 치커리 추출물을 5% 수준으로 식이에 첨가하여 SD계 수컷흰쥐에 2주간 자유 섭취시켜 혈청 및 간장의 지질 농도와 간장 MTP(microsomai triglyceride trasfer protein) 활성에 미치는 영향을 조사하였다. 체중 증가량, 장기 중량 및 식이 섭취량은 각군잔의 유의적 차이는 인정되지 않았다. 혈당치는 대조군과 볶음처리한 치커리군에 비교해서 볶음처리하지 않은 치커리군에서 증가하는 경향을 나타내었다. 혈청의 TG 농도는 치커리 첨가군에서 감소하는 경향으로 나타났으며, 혈청 총 콜레스테롤, 인지질 및 유리지방산 농도와 간장 지질농도는 실험군간의 유의적 치이는 없었으나, HDL콜레스테롤 농도는 치커리 첨가군에서 증가하는 경향을 보였다. 간장에서 중성 지질 합성의 조절효소로 알려진 PAP(phosphatidate phosphohydrolase)활성은 각 실험 군간의 유의적 치이는 없었다. 그러나, 중성지질-rich 리포단백질의 합성, 분비에 필수적인 간장 MTP활성을 대조군에 비교하여 치커리군에서 현저하게 저해되었다. 간장 MTP 활성과 혈청 중성지질 농도의 사이에 높은 정의 상관관계(r=0.81)가 인정되어, 본 실험에서 치커리 뿌리 추출물에 의한 혈청 중성지질 억제효과는 간장 MTP 활성의 저해에 기인하는 것으로 시사되었다.

  • This study was conducted to investigate the cholesterol and Triglyceride (TG) lowering and anti-obesity effects of water extract of vegetable formula (onion 25%, carrot 20%, Cabbage 20%, Sweet Pumpkins 20%, Chinese plum 5%, turmeric 5%, morus leaves 5%, SLS) in mice fed high fat-diet. ICR mice were divided into 3 groups; a normal diet group (ND), a high-fat diet group (HFD), a high-fat diet and SLS with 300 mg/kg treated group (HFD+SLS). Body fat gain was increased by high-fat diet and HFD+SLS group showed a definite weight loss. The total cholesterol level in the HFD+SLS group was 328.4 mg/dl which was 27.4% lower than that in the HFD group and the cholesterol-lowering effect of SLS was confirmed. The HFD + SLS group showed 118.1 mg/dl and the triglyceride level in the serum was decreased by 88.7% compared to the HFD group and SLS significantly decreased blood triglyceride levels. RT-PCR showed that the expression of PPAR-${\gamma}$ and the target gene SCD-1 was inhibited in a dose-dependent manner in the SLS-treated group. These results suggest that the SLS water extract may have a cholesterol and triglyceride-lowering effect and inhibit the expression of PPAR-${\gamma}$ and SCD-1 to have an anti-obesity effect.

  • This study was performed to offer the fundamental data for preventing and controlling the cardiovascular diseases of rural community women. The number of 168 women aged 40 to 50s who live in Kumsan-gun, Chungnam were selected for analysis after medical examination by a Kumsan-gun health center during the period of November to December in 1996. Total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol(HDL-C), blood pressure(BP), degree of obesity(BMI) and atherosclerosis index(AI) were measured and relation between these physical measurements to serum lipid levels were studied. The results were as follows; 1. Mean TC level, TG level, BP, BMI and AI were significantly increased with advancing age. 2. Mean TC level, TG level, BMI and AI of borderline BP group and hypertension group were significantly increased than those of normal BP group. 3. Mean TC level, TG level and AI of obesity group were significantly increased than those of normal BMI group. 4. Simple correlation analysis showed that the positive correlation between TC, TG, BP, BMI and AI, but the level of HDL-C was negative correlation with TG and AI. 5. In multiple regression analysis taking HDL-C level as the dependent variable and TG, TC, BP, BMI, Age AI as the independent variable, AI, TG, BMI, TC were significantly related to HDL-C.

  • In order to examine the effect of oil extraction methods on the charateristics of sesame oil, the fractionation pattern and fatty acid compositions of the each fraction of the oil were compared in the oil extracted by the three different extraction methods, that is, pressure extraction of roasted seed (RTP), acetone extraction of roasted seed (RTE) and acetone extraction of raw seed (RWE). The amount of triglyceride in RWE oil was slightly higher as 77.2% of the total lipid than that in RTP and RTE oil of 73.4%. The content of oleic and linoleic acid in glycolipld and fatty acid fractions, linoleic acid in triglyceride, and palmitic and stearic acid in phospholipid fractions from RTP and RTE oil were higher than those from RWE oil, but the oleic acid in triglyceride. Palmitic and stearic acid in free fatty acid, and oleic and linoleic acid in phospholipid from RTP and RTE oil were lower than those from RWE oil. The ratio of $C_{18}$ to $C_{16}$ fatty acids and unsaturated to saturated fatty acids in glycolipid and phospholipid fractions from RTP and RTE oil were higher than those from RWE oil, but the ratios in triglyceride and free fatty acid fractions from RTP and RTE oil were lower than those from RWE oil.

  • Rhodosporidium toruloides, an oleaginous yeast, can be used as a fast and reliable evaluation tool to screen new natural lipid-lowering agents. Herein, we showed that triglyceride (TG) accumulation was inhibited by 42.6% in 0.1% red radish coral sprout extract (RRSE)-treated R. toruloides. We also evaluated the anti-obesity effect of the RRSE in a mouse model. The body weight gain of mice fed a high-fat diet (HFD) with 0.1% RRSE (HFD-RRSE) was significantly decreased by 60% compared with that mice fed the HFD alone after the 8-week experimental period. Body fat of the HFD-RRSE-fed group was dramatically reduced by 38.3% compared with that of the HFD-fed group.

  • TCDD, one of the notorious toxic environmental pollutants, damages various organs including liver and is regarded as an endocrine disrupter. To investigate the effects of Houttuynia cordata Thunb (HCT) on the biochemical parameters of function, liver and serum of TCDD-treated rats were used. Seven days after the injection of TCDD (1 $\mu\textrm{g}$/kg), HCT (200 mg/kg) was administered to rats on every other day for four weeks. The lipidperoxide activity was examined by measuring the level of total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid and triglyceride (TG) in serum, and malondialdehyde (MDA) in liver tissue of rats. Result showed that lipidperoxidation was inhibited In the significant level when 2,3,7,8-TCDD-damaged rats were treated with HCT.

  • In order to develop an improved paclitaxel formulation vehicle, a micelle forming solubilizer, Aceporol 330 was synthesized. It was previously reported that Aceporol 330 provided the linearity of paclitaxel plasma pharmacokinetics. In this study, the single dose toxicity test and 2-week repeated dose toxicity test of Aceporol 330 was performed in beagle dogs after intravenous administration. Single dose and 2-week repeated dose toxicity test of Aceporol 330 showed fever/generalized erythema, severe vomiting, and diarrhea in beagle dogs. However, those toxicities were less severe than those of Cremophor EL. Blood chemistry analysis of 2-week repeatedly treated beagle dogs with Aceporol 330 showed significant elevation of total cholesterol (TCHO) and triglyceride (TG) compared to that of control group. Cremophor EL also significantly increased total cholesterol (TCHO) and triglyceride (TG) as much as Aceporol 330. Results from this study indicated that Aceporol 330 was less toxic than Cremophor EL. Based on the pharmacokinetic advantages and the low toxicity of Aceporol 330 in single dose and 2-week repeated dose toxicity test, Aceporol 330 has a potential for use as a safer solubilizer for paclitaxel than Cremophor EL.

  • Effects of methanol extract from turmeric (Curcuma longa L.) (CME) on underlying mechanisms of lipolysis were investigated in 3T3-L1 adipocytes. Compared to the control, lipid accumulation with 72 hr treatment of CME at the concentration $20\;{\mu}g/mL$ was significantly decreased by 19.9% as quantified by Oil red O dye. Intracellular triglyceride (TG) content was also lowered by 19.3%. To determine the mechanism for TG content reduction, glycerol release level was measured. Incubation of 3T3-L1 adipocytes with 15 and $20\;{\mu}g/mL$ of CME significantly elevated the level of free glycerol released into the cultured medium by 20.4 and 28.6%, respectively. In subsequent measurements using quantitative real-time polymerase chain reaction (PCR), mRNA levels of hormone-sensitive lipase (HSL) and adipose triglyceride lipase (ATGL) were significantly increased by 21.2 and 24.9%, respectively, at the concentration $20\;{\mu}g/mL$. Results indicated that CME stimulated lipolysis through induction of HSL and ATGL mRNA expressions, resulting in increased glycerol release.

  • The effects of three fractions, hexane (BHHH), chloroform (BHHC), and ethyl acetate (BHHE), from water extract of Benincasa hispida on the underlying mechanisms of adipogenesis were investigated in 3T3-L1 cells. Intracellular lipid droplets were stained with Oil Red O dye and quantified. Compared to control, lipid accumulation significantly decreased by 11% and 13% upon treatment with BHHC and BHHE, respectively at a concentration of 50 ${\mu}g/mL$. Intracellular triglyceride (TG) levels were also reduced by 21% and 16%, respectively, at the same concentration. To determine the mechanism behind the reductions in TG content and lipid accumulation, glycerol release and expression levels of adipogenic marker genes were measured. The levels of free glycerol released into culture medium increased by 13% and 17% upon treatment with BHHC and BHHE, respectively. In subsequent measurements using real-time polymerization chain reaction, the mRNA levels of $PPAR{\gamma}$, C/$EBP{\alpha}$, and leptin significantly decreased upon treatment with BHHE (45%, 67%, and 35%) in comparison with non-treated control. These results suggest that BHHE inhibits adipocyte differentiation by blocking $PPAR{\gamma}$, C/$EBP{\alpha}$, and leptin gene expression in 3T3-L1 cells, resulting in reduced lipid accumulation, increased glycerol release, and intracellular triglycerides.

  • Sweet potato (Ipomoea batatas L.) is widely used in Indonesia and other countries as a traditional medicine for the treatment of diabetes mellitus (DM). The MeOH extract of white skinned sweet potatoes (WSSP) was administered orally in doses of 100 and 200 mg/kg body weight in streptozotocin (STZ)-induced diabetic rats. Experimental diabetes was induced by a single dose of STZ (45 mg/kg, i.p.) injection. Oxidative stress was measured by tissue lipid peroxide (LPO) levels, serum aspartate transaminase (AST), alanine transaminase (ALT), total triglyceride (TG), total cholesterol (TC) and by antioxidative enzymatic activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione S-transferase in the liver. An increase in blood glucose, LPO level, AST, ALT, TG and TC levels was observed in the STZ-induced diabetic rats. Administration of MeOH extract of WSSP at a dose of 200 mg/kg for two weeks caused a significant reduction in blood glucose, LPO levels, AST, ALT, TG and TC levels in the STZ-induced diabetic rats. Furthermore, oral administration of MeOH extract showed significant improvement in the activities of antioxidant enzymes (SOD, GPx, and CAT) compared to STZ-induced diabetic rats. In conclusion, the obtained results clearly indicate the role of oxidative stress in the induction of diabetes, and that the protective effects of MeOH extracts of WSSP could be used to benefit diabetic patients.
