Objective This study investigated the effects of Jeoreongchajeonja-tang in a high-fat diet-induced obesity mouse model. Methods The study examined 9-week-old male mice (C57bl/6J) divided into four groups: the normal(C57bl/6J-Nr), control (high-fat diet only; HFD-CTL), positive-control (high-fat diet with Garcinia cambogia), and experimental (high-fat diet with Jeoreongchajeonja-tang; HFD-JCT) groups. After 7 weeks, the body weight, food efficiency ratio, organ weight, and visceral fat weight of the mice were measured. Blood serum tests, mRNA, liver histopathology, and epididymis adipocytes were also examined. Results Compared with the Control(HFD-CTL) group, the Experimental(HFD-JCT) group given Jeoreongchajeonja-tang showed significant reductions in absolute body weight and food efficiency ratio. The serum alanine aminotransferase, total-cholesterol, triglyceride, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, insulin-like growth factor-1, and leptin levels were significantly lower in the experimental group than in the control group. The serum adiponectin levels were significantly higher in the experimental group than in the control group. Compared with the control group, the experimental group showed significant reductions in absolute abdominal subcutaneous fat, epididymal adipose tissue, kidney adipose tissue, intestine adipose tissue, and liver, kidney and spleen adipose tissue weights. The C/EBP-${\beta}$, leptin, and SREBP1c/ADD1 mRNA expression were significantly lower in the experimental group than in the control group, while the UCP-2 and adiponectin mRNA expression were significantly higher. Compared with the control group, the experimental group showed a significant reduction in the absolute adipocyte area in the liver and epididymal adipose tissue. Conclusion Jeoreongchajeonja-tang has an anti-obesity effect. Additional clinical studies are expected.

In experiment 1, rats (n＝6) fed diet containing 10 g/kg cholesterol for 4 wk (control) with either no amaranth (control), amaranth grain (300 g/kg, AG) or amaranth oil (90 g/kg, AO). Both the AG and AO groups had lower concentration of serum and hepatic cholesterol and triglyceride than the controls (p < 0.05). Fecal excretions of cholesterol and bile acid in AO group increased about 4 fold and 2 fold, respectively, while AG affected only bile acid excretion (p < 0.05). In experiment 2, rats (n＝6) were fed the cholesterol diet for 4 wk and injected intraperitoneally with saline (control) or amaranth squalene (AS) for 7d. The hypolipidemic effect of AS was evident in both serum and liver. Fecal excretions of cholesterol and bile acid were greater (p < 0.05) in AS than control. HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase activity was reduced in AS group (11.6%, p=0.13). This study suggests that the cholesterol-lowering effect of AS is mediated by greater fecal elimination of steroids through interference with cholesterol absorption.

The study examined the effects of dietary green tea powder supplementation on blood glucose, and plasma and liver lipid concentrations in diabetic rats. Twenty-five male Sprague-Dawley rats (body weight $200{\pm}5\;g$) were divided into two groups (diabetic and non-diabetic), which were each randomly divided into two subgroups that were fed a control and 1% green tea powder-supplemented diet. Serum and liver lipid concentrations were measured by established techniques. Low density lipoprotein-cholesterol (LDL-C) was calculated from an established equation. Body weight gain and feed efficiency ratio were lower in diabetic rats than in non-diabetic rats regardless of diet. There were no differences in weight gain in diabetic and non-diabetic rats consuming the control and green tea powder-supplemented diets. The levels of fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index of diabetic rats were significantly higher than that of non-diabetic rats. Conversely, the levels of high density lipoprotein-cholesterol (HDL-C) of diabetic rats was significantly lower than that of non-diabetic rats. Fasting plasma glucose, serum total cholesterol, triglyceride, LDL-C and atherogenic index were significantly lower in diabetic rats fed the green tea powder diet than in rats fed the control diet, and HDL-C was significantly higher in rats fed the green tea powder diet than in rats fed the control diet. The content of liver total cholesterol and triglyceride of diabetic rats were significantly higher than that of non-diabetic rats. Liver total cholesterol and triglyceride were significantly lower in diabetic rats fed green tea powder-supplemented diet than in rats fed the control diet. It is concluded that green tea powder supplementation positively influences blood glucose and lipid metabolism in diabetic rats. The present study, although not directly applicable to humans, may have some implications for individuals who habitually consume green tea powder.

The effectsof garlic vinegar supplementation on body weight, blood blucose, and plasma triglyceride and cholesterol were investigated in streptozotocin -induced diabetic rats fed high-cholesterol(1%) diet for 4 wk. The garlic vinegar was made by fermenting 20% frsh garlic juice. There was no effect of garlic vinegar on body weight, plasma glucose or triglyceride concentrations in the diabetic rats. Plasma total -cholesterol concentrations were unaffected by garlic vinegarr supplementation. However, plasma LDL-cholesterol concentrations and atherogenic index were significantly lower in the diabetic rats supplemented with garlic vinegar diet than tin the cotnrol rats. The diabetic-rats supplemented with garlic vinegar not only had increased HDL-cholesterol levels but had decreased LDL-cholesterol. This alteration in the HDL/LDL-cholesterol ratio in the diabetic rats may decrease the risk of atheroscelrosis. Therefore, the over-all effect of garlic vinegar supplement may contribute to the antiatherogenic role in streptozotocin-induced diabetic rats.

자색고구마 열수추출물의 간 보호 기능을 확인하기 위해 C57BL/6 마우스를 사용하여 시험하였다. 지방간 유도를 위해 8주간 고지방/콜레스테롤 식이를 급여하였으며, 자색고구마 열수추출물은 1.25, 2.5, 5%의 수준으로 식이에 함께 넣어 같은 기간 동안 제공하였다. 간 조직의 병리학적 분석, 혈장 ALT 활성도, 간 및 혈장의 TC 수준을 바탕으로 비알콜성 지방간 모델이 형성되었음을 확인하였다. 고지방/콜레스테롤 식이의 급여는 식이섭취량을 감소시켜 총 에너지 섭취량은 시험군간 차이가 없었으나, 포화지방을 급원으로 하였을 때 지방세포의 비대와 혈장 TC, 간 TC, 간의 지방구를 증가시키는 것으로 관찰되었다. 한편 자색고구마 열수추출물을 고지방/콜레스테롤 식이와 함께 섭취시킨 결과, 고지방/콜레스테롤 식이로 인한 지질대사 이상을 유의하게 변화시키지 못해 혈액 및 간 손상 지표를 개선시키지 못하였으나, 지방조직의 크기는 작게 유지하고 간의 지방구 형성은 억제하는 것으로 관찰되었다. 이상의 결과로 자색고구마 열수추출물은 지질대사 개선을 통해 간 보호 효과를 갖음을 알 수 있었다. 향후에는 자색고구마 열수추출물이 지방세포-간의 상호 지질대사에 미치는 영향을 추가적으로 연구해야 할 것으로 사료된다.

The purpose of the present study was to examine the effects of water extracts from red pepper seeds powder on antioxidative enzyme activities and oxidative damage in groups of rrats fed high-fat and high-cholesterol diets group (HFC). The Rrats were divided into the following five experimental groups which are : composed of a normal diet group, a high fat high cholesterol diet group, and a high fat high cholesterol diet group supplemented with different amounts contents (1%, 2% and 4%) of red pepper seeds powder water extracts supplemented groups (HFCW1, HFCW2 and HFCW4, respectively). Body weight gains and food intake were lower ofin the red pepper seed water extracts groups were lower than those inof the HFC group. Hepartic xanthine oxidase (XOD) activity was decreased in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic glutathione peroxidase (GSH-px) activitiyactivity was increased in the HFCW4 group compared to the HFC group. Hepatic superoxide radicals within the mitochondria and microsomes of cells were significantly reduced in the HFCW2 and HFCW4 groups compared to the HFC group. Hepartic hydrogen peroxide in the cytosol was significantly reduced in the HFCW3 and HFCW4 groups compared to the HFC group. Hepatic carbonyl values in the microsomes and mitochondria were significantly reduced in the HFCW4 group compared to the HFC group. Hepartic thiobarbituric acid reaction substance (TBARS) activity was decreased in the HFCW2 group compared to the HFC group. These results suggest that water extracts of red pepper seeds powder may reduce oxidative damage by activation of antioxidative defense systems in rats fed high fat-high cholesterol diets.

Objectives This study is to investigate the effects and mechanisms of Imyo-san (IMS) on the obese mice model induced by high-fat diet. Methods Antioxidative capacity was measured by in vitro method. C57BL/6 mice were randomly assigned into 5 groups (n=7). Normal group was fed general diet (Normal). The other 4 groups were fed high fat diet (HFD) with water (Control), with Garcinia gummi-gutta (GG, Garcinia gummi-gutta 200 mg/kg), with low-dose IMS (IMSL, Imyo-san 0.54 g/kg) and with high-dose IMS (IMSH, Imyo-san 1.08 g/kg). Results IMS showed high radical scavenging activity. After 6 week experiment, body weight, food intake, food efficiency ratio (FER), epididymal fat and liver weight, triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, very low density lipoprotein (VLDL) cholesterol, sterol regulatory element-binding protein-1 (SREBP-1), phospho-acetyl-CoA carboxylase (p-ACC), fatty acid synthase (FAS), stearoyl-CoA desaturase-1 (SCD-1), SREBP-2, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), phospho-liver kinase B1 (p-LKB1), phospho-AMP-activated protein kinase (p-AMPK), peroxisome proliferator-activated receptor 𝛼 (PPAR𝛼), peroxisome proliferator-activated receptor 𝛾 coactivator-1𝛼 (PGC-1𝛼), uncoupling protein-2 (UCP-2), carnitine palmitoyltransferase 1A (CPT-1A), and histology of liver and epididymal fat were measured and analysed. Body weight gain, FER, liver and epididymal fat weight of IMS groups were significantly decreased. There were significant improvements in blood lipids with less TG, TC, LDL-cholesterol, VLDL-cholesterol and more HDL-cholesterol. Proteins associated with lipid synthesis (SREBP-1, p-ACC, FAS, SCD-1) and cholesterol (SREBP-2, HMGCR) was improved. Factors regulating lipid synthesis and lipid catabolism (p-LKBI, p-AMPK, PPARα, PGC-1α, UCP-2, CPT-1A) were increased. In histological examinations, IMS group had smaller fat droplets than control group. All results increased depending on concentration. Conclusions It can be suggested that IMS has anti-obesity effects with improving lipid metabolism.

고지방식이로 고지혈 및 비만이 유도된 흰쥐에서 브로콜리 싹 에탄올 추출물 투여로 인한 혈 중 지질대사 개선 및 지방조직의 항비만효과에 미치는 영향에 대하여 조사하였다. 5주령 된 흰쥐 수컷 36마리를 1주일간 적응시킨 후 정상 식이군(ND), 고지방식이군(HFD), 정상식이와 브로콜리 싹 에탄올 추출물 저용량 병합 투여군(ND-BSL), 정상식이와 브로콜리 싹 에탄올 추출물 고용량 병합 투여군(ND-BSH), 고지방식이와 브로콜리 싹 에탄올 추출물 저용량 병합 투여군(HFD-BSL) 및 고지방식이와 브로콜리 싹 에탄올 추출물 고용량 병합 투여군(HFD-BSH)으로 나누어 4주간 사육하였다. 고지방식이로 증가되어진 체중증가량은 브로콜리 싹 에탄올 추출물 고용량 병합 투여로 유의하게 감소되었으며, 정상식이군(ND)과는 비슷한 수준으로 저하되었다. 고지방 식이군들(HFD, HFD-BSL 및 HFD-BSH)이 정상식이군들 (ND, ND-BSL 및 ND-BSH)에 비하여 식이섭취량은 낮았으나, 식이효율은 높게 나타났다. 간조직의 무게는 실험 군간에 유의차가 없었으나, 부고환 및 장간막지방조직의 무게는 고지방식이를 급여한 흰쥐에게 브로콜리 싹 에탄올 추출물을 고용량 병합 투여한 경우에는 고지방식이에 비하여 유의하게 저하되었다. 고지방식이로 증가되어진 혈청 중의 ALT 및 AST 활성, 중성지방, 총콜레스테롤 및 LDL-콜레스테롤 함량, 심혈관위험지수와 동맥경화지수도 브로콜리 싹 에탄올 추출물 고용량 병합 투여로 감소되었다. 혈청 중의 ALP 활성은 실험 군 간에 유의차가 없었다. 혈청 중의 HDL-콜레스테롤 함량은 정상식이군(ND)에 비하여 고지방식이군(HFD)이 유의하게 감소하였으나, 정상식이 혹은 고지방식이를 급여한 흰쥐에게 브로콜리 싹 에탄올 추출물을 투여하였을 경우에는 영향을 미치지 않았다. 고지방식이로 증가되어진 간조직과 장간막지방조직 중의 총콜레스테롤 함량은 브로콜리 싹 에탄올 추출물 병합 투여로 저하되었다. 지방조직 중의 HR-LPL과 TE-LPL 활성 모두 정상식이군 (ND)에 비하여 고지방식이군(HFD)이 증가하였고, 브로콜리 싹 에탄올 추출물 고용량 병합 투여한 모든 군은 고지방 식이군(HFD)에 비하여 유의하게 감소되었으나 정상식이군 (ND)과는 비슷한 활성을 나타내었다. 특히 브로콜리 싹 에탄올 추출물의 효과는 고용량 병합 투여군이 저용량 병합투여군에 비하여 더 좋은 효과를 나타내었다. 혈청 및 조직 중의 지질 함량 변화는 정상식이군들(ND, ND-BSL 및 ND-BSH) 간에는 유의차가 없었다. 따라서 고지방식이를 급여하면서 브로콜리 싹 에탄올 추출물을 병합 투여 시에만 효과가 있는 것으로 여겨진다. 이상의 결과 브로콜리 싹 에탄올 추출물이 체중 및 지방조직의 무게 감소와 더불어 혈청지질 개선 효과와 LPL 활성을 저하시켜 고지혈증 예방효과와 지방축적 억제 효과가 있는 것으로 사료되나 브로콜리 싹 추출물의 어떤 성분이 콜레스테롤 저하효과 및 비만을 억제시킬 수 있는지는 보다 자세한 연구가 요구된다.

As the obesity has been known to be related with the hyperlipidemia, cardiovascular disease, cerebral apoplexy, fatty liver, and other chronic diseases, recent researches have focused on the functional food materials and their anti-obesity activities. This study was performed to study the effects of vanilloid family capsaicin, major pungent ingredient of hot chillies and peppers, on anti-obesity activities. ICR male mice were fed one of the pellet diet, basal diet, and high fat diet with capsaicin (45 $\mu\textrm{g}$/day) solution for 5 days. Mice in the corresponding control groups were given water for 5 days. In results, capsaicin reduced body weights in any diet groups. Percent weight and cell size of the abdominal white adipose tissue in mice on the high fat diet with capcaicin were significantly lower compared with those in mice on the high fat diet with water. However, percent brown adipose tissue weight per body weight in mice on the high fat diet was not affected by capsaicin. Capsaicin reduced the levels of s-triglyceride and s-total cholesterol in the pellet diet or high fat diet groups. There was no difference in the s-protein levels between the capsaicin group and the control water group. These data indicate that 1) orally administered capsaicin has a reducing effect on the blood triglyceride and total cholesterol levels, and 2) capsaicin has lowering effects on the body weight, percent weight and cell size of the abdominal white adipose tissue.
