  • This study was conducted to investigate the effects of taro powder on body weight and lipid metabolism in high fat and cholesterol fed mice. C57BL6 mice were divided into four groups; normal (normal) diet group, a high fat and cholesterol (HF) diet group, and high fat and cholesterol diet groups with 20% taro powder (HF-taro 20%) and 30% taro powder (HF-taro 30%). After 8 weeks, body weight in the HF group increased to 175% of the normal group, while those of HF-taro 20% and HF-taro 30% group decreased by 12.5 and 14% compared to the HF group. The HF-taro 20% and HF-taro 30% groups had significantly reduced epididymal adipose tissue weight. Plasma triglyceride, total cholesterol, and LDL-cholesterol concentrations were significantly higher in the HF group than those in the normal group, while their amounts were significantly diminished in the HF- taro 20% and HF- taro 30% groups. Furthermore, the leptin and insulin concentrations in blood plasma decreased significantly in the HF-taro 20% and HF-taro 30% groups. Accumulation of triglycerides and cholesterol in the liver was significantly inhibited in the HF- taro 20% and HF-taro 30% groups through liver weights, a blood analysis, and histological findings. These results suggest that taro powder may be an effective material for anti-obesity by reducing plasma triglyceride and cholesterol levels.

  • The aim of this study was to develop hydroponic-cultured ginseng vinegar (HGV) containing ginsenoside Rg2 in order to its anti-obesity and anti-hyperlipidemic effects in C57BL/6J mice. HGV was prepared by two-stage fermentation. The ginsenoside Rg2 contained in acetic acid-fermented HGV increased by 4.0 times compared to that in pre-fermented HGV. To measure the anti-obesity effect of HGV, thirty two mice were randomly divided into four groups: normal diet group (ND), high-fat diet group (HFD), high-fat diet-supplemented with HGV group (HGV), and high-fat diet-supplemented with green tea extract group (GT). Body weight, fat weight, and liver weight decreased in the HGV group. The HGV group also showed lower plasma levels of low-density lipoprotein (LDL)-cholesterol and triglycerides, and higher levels of high-density lipoprotein (HDL)-cholesterol compared to the corresponding levels in the HFD group. Furthermore, there were significant decreases in plasma aspartase aminotransferase (AST) and alanine aminotransferase (ALT) levels in the HGV group compared to the corresponding levels in the HFD group. These results suggest that HGV can be used as an anti-obesity therapeutic agent or functional ingredient.

  • The primary role of lipoprotein lipase(LPL) is the hydrolysis of triglycerides(TG) from the core of triglyceride-rich lipoproteins such as chylomicrons and very low density lipoproteins in plasma. Fatty acids liberated by LPL on capillary endothelial surfaces are available for tissues as energy sources especially in muscles or for storage in the form of TG in adipose tissues. Therefore, as the candidate gene related to the carcass traits of the beef cattle, we have directly sequenced the exon 5${\sim}$exon 6 region in the bovine LPL gene for discovery of single nucleotide polymorphism(SNP) with 24 unrelated Hanwoo(Korean cattle). Novel eight sequence variants were detected: three loci on exon 5, three on intron 5 and two on exon 6. All SNPs identified were strongly linked each other, and one hundred twenty eight Hanwoo samples were genotyped one SNP on intron 5 using PCR-restriction fragment length polymorphism method by digestion with Hae III restriction enzyme. The allele frequency of the polymorphism was 0.76 and 0.24. The effects of this polymorphism on the breeding values of the carcass weight, loin muscle area, back fat thickness and marbling score were analyzed using least square methods of SAS GLM. The marbling score of BB genotype was significantly higher than those of AA and AB genotypes(P<0.05). This result indicates that this polymorphism may be associated with the variation of marbling score. Further study is warranted to investigate the phenotypic association in Hanwoo.

  • This study was carried out to evaluate the effects of the addition of different levels of CFP (Cordyceps with fly pupa) on growth performance in broiler chickens. 400 broiler chicks (Ross 308, 1 day old) were sorted randomly into 4 treatment groups and fed experimental diets for 35 days. The treatment groups were divided into a control group not fed with CFP (T1), and treatment groups fed with CFP 2.0% (T2), CFP 3.5% (T3), and CFP 5.0% (T4). Although the broilers' weight gain and feed efficiency were significantly higher (p<0.05) in the T3 group throughout the entirety of the test period, no statistically significant differences were noted among the T1 and T2, T4 groups. Triglyceride in the blood, total cholesterol, and LDL-C were significantly lower in the CFP treatment groups than in the control group (p<0.05). The blood lipid reduction rate ranged from 5.32 to 10.63% for triglycerides, from 9.23 to 12.62% for total cholesterol, and from 44.67 to 53.81% for LDL-C in the CFP treatment groups relative to the control group. The abdominal fat weight ratio was reduced significantly in the CFP treatment groups (p<0.05) compared with the control group, with a reduction rate range of 17.67-21.68%. Broiler carcass weight, carcass rate, and ratios of breast muscle, skin and thigh muscle weights to carcass weight were significantly higher in the T3 group, and statistically significant differences were noted among the T1 and T2, T4 groups (p<0.05). Enteropathogenic E.coli and Salmonella were lower in the CFP treatment groups than in the control group, whereas the beneficial bacteria Bifidobacteria were significantly higher in the CFP treatment groups than in the control group (p<0.05). These findings suggest that the Cordyceps with fly pupa can improve the carcass characteristics and body weight gain in broiler chickens.

  • In order to effectively utilize of granular ark and ark shell, lipid and fatty acid compositions, free amino acids, nucleotides and their related compounds and minerals in the muscle and viscera of raw and cooked specimens were analyzed. The major constituents of non-polar lipids in the granular ark and ark shell were triglycerides, which showed higher content in viscera than the muscle. The polar lipids in the granular ark and ark shell were mainly consisted of phosphatidylcholine and phosphatidylethanolamine. The major fatty acids of total lipid were 16:0, 20:5n-3, 18:1n-9, 16:1n-7, 18:0 and 22:6n-3 both the granular ark and ark shell. The major nucleotides and the related compounds were adenosine monophosphate and adenosine diphosphate and they had higher content in the muscle than in viscera both samples, free amino acids such as taurine, glycine, alanine, glutamic acid, phenyl alanine and aspartic acid were abundant both the granular ark and ark shell. In the raw muscle of granular ark, glycine, alanine and $\alpha$-amino-iso-butyric acid were high level, but glutamic acid, aspartic acid and phenyl alanine were low level compared with those of cooking muscle. In the raw muscle of ark shell, taurine and $\alpha$-amino-iso-butyric acid were high content, but the glutamic acid and aspartic acid were low level compared with those of cooking muscle. Minerals in the granular ark and ark shell were chiefly consisted of potassium, sodium, magnesium, iron and calcium.

  • 그람 음성균의 감염에 의한 만성 염증질환인 치주염이 동맥경화를 동반한 허혈성 심장질환 (협심증이나 심근 경색)을 일으킬 수 있는 위험인자로 작용할 수 있다는 보고가 있었다. 그러나, 그 기전에 관해서는 명확하게 알려져 있지 않다. 작용기전의 하나로서, 치주염에 의해 치주조직에서 국소적으로 생긴 염증성 싸이토카인(IL-1${\beta}$, IL-6, $PGE_2$, TNF-${\alpha}$)이 혈행을 따라 이동하여 심혈관에서 동맥경화를 일으킬 수 있다는 가설이 제시되고 있는데, 이 가설을 검증해 보고자 한다. 서울대학교 병원 순환기 내과에 불안정 협심증이나 심근경색으로 입원한 환자 및 과거 이 질환의 병력을 갖고 있거나 검진 목적으로 내원하여 관상동맥 조형술을 받은 환자들 중 동맥경화로 진단받은 사람을 실험군(24명)으로 하고, 동맥경화로 진단받지 않은 사람을 대조군(12명)으로 하였다. 치주질환의 활성도를 나타내는 치은 지수, 치태 지수, 치주낭 깊이, 부착 상실을 측정하였다. Paper strip을 실험대상 치아(Ramfjord's teeth)들 중에서 가장 깊은 치주낭을 가진 두 개의 치아를 택하여 각 치아의 가장 깊은 치주낭에 30초간 삽입한 후 밀폐된 plastic tube에 넣고 ELISA kit를 이용하여 IL-1${\beta}$, IL-6, TNF-${\alpha}$, $PGE_2$의 농도를 측정하였다. 환자의 plasma에서도 동일한 싸이토카인의 농도를 측정하였다. 설문조사를 통해 동맥경화의 위험 인자로 간주되어온 고혈압, 당뇨, 가족력, 심근경색이나 협심증의 기왕력, 흡연의 유무를 기록하였다. 혈액검사를 하여 total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, WBC, CRP (C-reactive protein)의 농도를 측정하였다. 치주조직에 대한 임상 검사 결과 치은의 염증상태를 나타나는 지표인 치은 지수에서만 실험군이 대조군에 비해 유의할 정도 (p=0.0174)로 높게 나타났고, 만성적인 염증의 결과로 인한 치조골의 사실 정도를 나타내는 치주낭 깊이나 부착 상실에서는 유의할 만한 차이를 보이지 않았다. 치주낭에서 측정한 염증성 싸이토카인 중 IL-1${\beta}$, $PGE_2$가 실험군에서 유의할 만한 차이 (p=0.005, 0.022)를 보이며, 더 높은 농도로 나타났고, TNF-${\alpha}$는 대조군에서 유의성 있게 (p=0.009) 높게 나타났다. 그러나, plasma의 싸이토카인이나, serum lipid/lipoprotein, C-reactive Protein, WBC는 유의할 만한 차이를 보이지 않았다. 또한 치은열구액내의 싸이토카인과 이에 상흥하는 싸이토카인 간에 상관관계는 관찰되지 않았다. 다변량 로지스틱 회귀분석 결과, 치은열구액내의 IL-1${\beta}$와 TNF-${\alpha}$ 만이 동맥경화와 유의성 있는 관련성을 보였고, 특히 IL-1${\beta}$와 교차비는 273으로 상당한 관련성을 보여주었다. 결론적으로, 치주조직에서 국소적으로 생긴 염증성 싸이토카인이 그대로 혈행으로 이동하여 혈장내의 싸이토카인 농도를 높이는 것은 아니다. 그러나, 치주염으로 인해 치은열구내액내에 국소적으로 증가된 염증성 싸이토카인은 동맥경화와 상당한 관련성을 가진다.

  • This study examined the effect of Momordica charantia L. (bitter melon: BM) on lipid and hepatic antioxidative enzyme levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats by injection of streptozotocin (STZ), and rats were fed for 4 weeks with experimental groups divided into four groups: a normal control group, STZ-control and STZ-BM 5% & STZ-BM 10% treated groups. Levels of free fatty acids (FFA), high-density lipoprotein cholesterol (HDL-chol), triglycerides (TG) in plasma and malondialdehyde (MDA) & protein in liver, catalase (CAT), superoxide dismutase (SOD), glutathione-S-transferase (GST), and xanthine oxidase (XOD) were measured in liver cytosol. Level of HDL-chol significantly increased in the STZ-BM 5% diabetic group. TG & FFA levels were significantly higher in all diabetic groups compared to the control group. MDA and protein levels were significantly higher in the STZ-BM 5% group compared to all other experimental group. CAT level was higher in the supplementary group with BM compared to the STZ-control group, although the difference was not significantly different. SOD level was not significant in any experimental groups. GST level was significantly higher in the BM-treated groups compared to the STZ-control group. XOD level was significantly lower in the BM 5% group and significantly decreased in all experimental groups. These results show that supplementation of BM fruit powder may have beneficial effects on diabetic complications and damage caused by oxidative stress.

  • The effects of goat's beard (Aruncus dioicus var ramtschaticus Hara) ethanol extracts (AD) on the streptozotocin-induced diabetic symptoms and oxidative stress in rats were assessed. Experimental plots were divided into normal controls (NC), diabetes controls (DM), diet with 0.3% AD after diabetes induction (SA), and diet with 0.6% AD after diabetes induction (SB), then fed for 5 weeks. In the SA and SB groups as compared with the DM group, diabetic symptoms including weight loss, increase in feed and water intake, and enlargement of the liver and kidney were improved. The levels of blood glucose and serum fructosamine were reduced by $17.9{\sim}27.2%$ and $25.6{\sim}32.6%$, respectively. The activities of alanine aminotransferase, aspartate aminotransferase and the levels of triglycerides, total cholesterol, and LDL-cholesterol in the serum were reduced by $25.6{\sim}30.3$, $42.37{\sim}55.51$, $26.85{\sim}30.44$ and $37.29{\sim}39.11%$, respectively, whereas the level of HDL-cholesterol was increased by $37.29{\sim}39.11%$. Hepatic total (T) and O type (O) activities of xanthine oxidoreductase, O/T ratio(%) and level of lipid peroxide were significantly decreased, while the level of glutathione was increased, and also the activities of superoxide dismutase and glutathione S-transferase were increased by $56.84{\sim}94.90%$ and $57.14{\sim}68.92%$, respectively. In the above results, it was noted that AD has an antidiabetic effect which alleviated hyperglycemia and the AD reduced and/or prevented the tissue damage caused by diabetes yia the inhibition of reactive oxygen species (ROS) generating systems concurrent with an increase in ROS scavenging.

  • Obesity is a pro-inflammatory state that contributes to the development of metabolic disorders such as hyperlipidemia, insulin resistance, type 2 diabetes, non-alcoholic fatty liver, and cardiovascular disease. In this study, we evaluated the inhibition of adipogenesis in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice by Peucedanum japonicum Thunberg L. water extract (PJT). Lipid accumulation measurement indicates that PJT markedly inhibited adipogenesis in a dose-dependent manner. RT-PCR results demonstrated that the mRNA expression of adipogenic transcription factors such as peroxisome proliferator-activated receptor-γ (PPARγ) and CCAAT/enhancer binding protein-α (C/EBPα) in 3T3-L1 cells were significantly down-regulated by PJT treatment. Oral administration of PJT (100, 300, and 500 ㎎/㎏, b.w/daily for 4 weeks) was conducted in high-fat diet induced obese mice and C57BL/6 mice. The PJT-administered group of HFD-induced mice had a lower body weight gain, along with decreased serum levels of glucose, triglycerides, and total cholesterol compared with the control mice, however, the HDL-cholesterol/total cholesterol ratio was increased. Furthermore, the elevated mRNA expression levels of adipogenesis related genes in the white adipose tissue of obese mice were significantly suppressed by PJT. These results indicate that PJT exhibits anti-obesity effects in obese mice by decreasing in serum lipid levels and lipogenesis related gene.

  • The purpose of this study was to investigate the effects of a 12 week weight control program, which included nutrition education and regular physical fitness, on body weight, degree of obesity, BMI, and lowering of blood lipids in 16 obese male elementary school students. Changes in waist and hip circumferences and their ratios were measured at the conclusion of the 12 week program conducted from September 9 to November 25, 2005. Body weight after 12 weeks on the program slightly reduced from 55.4${\pm}$10.9 kg to 54.4${\pm}$9.7 kg. Degree of obesity and BMI decreased from 121.3${\pm}$8.1%, and 25.9${\pm}$3.3 to 120.0${\pm}$8.2% and, 25.6${\pm}$2.7, respectively. Body fat percentage decreased slightly from 38.3${\pm}$4.7% to 37.9${\pm}$5.2%. Waist to hip ratio did not change after 12 weeks. There were slight changes in weight of body fat and lean body mass from 22.12${\pm}$6.53 kg and 34.56${\pm}$4.75 kg to 21.68${\pm}$6.05 kg and 34.70${\pm}$4.54 kg, respectively. Also, after 12 weeks on the weight control program, body, waist, and hip circumferences decreased. However, there were no significant differences among the blood lipid components, including triglycerides, total cholesterol, and HDL-cholesterol. Finally, body weight, degree of obesity, BMI, and body fat showed more significant correlations to waist, hip circumference and their ratio than to blood lipid levels.
