전 세계적으로 폭발적으로 증가하고 있는 비만은 만병의 근원이다. 동시에 대사성질환의 발병을 증가시키는 결정적인 역할을 하고 있다. 이러한 상황을 극복할 수 있는 안전하고 효능이 우수한 약의 개발이 매우 시급하다. 시판되는 약들은 예견할 수 없는 지방변으로 실제생활을 매우 불편하게 하는 부작용과 우울증 및 자살충동 등의 심각한 부작용을 유발시키고 있다. 특히 생명을 위협하는 약은 시판이 금지되었다. 200여종의 한약재들을 In vitro screening (pancreatic lipase inhibition, PDE inhibition, c-AMP activity), ex vivo screening (lipolytic action on fat pad), short term animal screening(혈중 TG 함량 분석)을 토대로 long term animal model에서비만 예방 및 치료 효능을 검증하기 위하여 호장근 부탄올 분획을 선정하였다. 고지방 사료로 비만을 유도한 rat (Diet induced obesty (DIO) rat)에서 비만 치료 효능이, 고지방 사료로 비만을 유도한 ICR-mice에서 비만 예방 효능이 우수함을 입증하였다 (체중감소, 지방세포의 크기억제, 지방간 예방/치료(간무게, TG함량, 간 색상, 고지혈증 증상억제), 혈중 TNF-a, IL-6, leptin, adponectin 등, 간 조직에서의 pAMPK, SOCS, NF-${\kappa}B$ DNA biding activity, ACC level, FAS expression, CPT-1 activity의 정상화). 호장근 부탄올 분획의 이러한 효능은 AMPK 작용과 CPT-1 작용을 활성화하고 동시에 지방산 합성 억제와 지방산 산화를 촉진함으로 인함임을 규명하였다. 동시에 비만으로 인한 pancreatic beta cell의 파괴를 예방함으로 인슐린 내성을 예방(치료)함을 입증하였다. 이는 AMPK 활성화와 SOCS-3 단백질 억제와 NF-${\kappa}B$-DNA 결합 억제로 인함임을 증명하였다. 3T3-L1 지방 세포주에서 lipogenesis 예방(치료) 및 lipolytic effect에 관여하는 인자들의 변화를 확인하였다. 이는 Multi-compounds-multi-targets에 의한 시너지 효과임을 알 수 있었다.

목적 : 인진약침이 고지방식이로 유발된 비만 ICR mice에서 비만 및 동반 대사이상에 미치는 효과와 그 기전을 연구하고자 한다. 방법 : 인진약침의 비만 예방효과를 검증하기 위하여, 4주간 고지방식이를 급여하면서 150mg/kg 또는 300mg/kg의 인진약침을 양측 비수($BL_{20}$)에 교대로 매일 피하에 시술하였다. 또한 인진약침의 비만 치료효과를 검증하기 위하여, 4주간 고지방식이를 급여한 비만 ICR mice에 추가 4주간 고지방식이를 유지하면서 300 mg/kg 인진약침액과 vehicle control로써 등량의 distilled water를 양측 비수($BL_{20}$)에 교대로 매일 피하에 약침시술하였다. 인진약침의 항비만효과와 기전을 알아보기 위해, 체중, blood glucose, insulin, total cholesterol, triglyceride, non-esterified fatty acid (NEFA), AST, ALT levels 등 대사지표를 측정하고 부고환조직의 조직학적 관찰을 시행하였으며, AMPK activation과 adipocyte differentiation, fatty acid ${\beta}$-oxidation 및 thermogenesis와 관련된 gene expressions을 평가하였다. 결과 : 인진약침의 치료를 통하여 고지방식이 급여로 인한 체중의 증가가 억제되었을 뿐만 아니라, 비만 ICR mice의 체중을 감소시켰으며, glucose 및 lipid homeostasis를 개선시켰으며 지방조직의 증식을 억제하였다. AMPK의 phosphorylation과 CPT-1 및 UCP2의 발현을 증가시켰으며, PPAR-${\gamma}$, C/EBP${\alpha}$, aP2, LPL,FAS, SCD-1의 발현을 억제하였다. 결론 : 인진약침은 고지방식이 유도 동물모델에서 비만 및 동반 대사이상을 개선시키는 효과가 있으며, 이는 식이억제에 의한 2차적 효과라기 보다는 energy expenditure를 증가시키고, pre-adipocyte differentiation 및 proliferation을 억제하며, lipogenesis를 억제하고 lipolysis를 증가시키는 효과에 의한 것으로 사료된다.

In order to determine the possibility that Chrysanthemum indicum L. cultured with Lactococcus lactis (CILL) is a material for obesity suppression food, the body weight, body fat mass, and T cells were determined in C57BL/6 mice induced by a high fat diet. The CILL (25.15±2.44 g) demonstrated weight loss from week 4 onward and maintained a low weight gain from week 1 to week 8 (1.00±0.53 g). The 8-week body weight (30.38±4.17 g) indicated loss of 13.15% when compared to the HFD (60% high fat diet, 34.99±2.09 g). Fat mass decreased to 10.3022±2.8813 g, and the absolute liver weight decreased relative to that in the HFD. CD4+ T cells were 4.84±1.33%, CD8+ T cells 7.02±2.26%, and CD4+CD8+ T cells 1.46±0.81%, which were all higher than those in the HFD. As a result, CILL can be used as a material for preventing obesity as an effective measure toward reducing weight when consumed orally.

Pancreatic lipase and ${\alpha}$-amylase inhibitory activities in purified extracts of pumpkin and job's tear were studied. Pancreatic lipase inhibitory activity was determined by measuring the rate of releasing oleic acid from triolein, and ${\alpha}$-amylase inhibitory activity was determined by iodometric method. The extracts of pumpkin and job's tear were purified using silica gel and C-18 gel column chromatographies. Treatment of pumpkin extract $(120\;{\mu}g/mL)$ in 3T3-L1 preadipocyte decreased differentiation about 95% and blocked accumulation of lipid. Body weights of rats fed high-fat diet containing dietary supplement decreased about 13% as compared with those fed only highfat diet. These results revealed dietary supplement is a good obesity-reducing material for decreasing lipid and carbohydrate absorptions.

It is researched to elucidate the effects of Taeumjowuitang(TE,太陰調胃湯), Sibimikwanjungtang(SE, 十二味寬中湯) and Yangkeogsanwhatang(SY,凉膈散火湯) on the obesity induced by gold thioglucose and the differentiation and growth of preadipocyte 3T3-L1 in the mouse. The result were as follows: 1. TE,SE and SY extracts improved the blood level of transaminase in the obese mouse induced by gold thioglucose. 2. TE,SE and SY extracts inhibited the increase of liver fat and body fat in the obese mouse induced by gold thioglucose. 3. TE,SE and SY extracts inhibited the increase of body weight in the obese mouse induced by gold thioglucose. 4. TE,SE and SY extracts inhibited the growth of undifferentiate preadipocyte 3T3-L1. 5. TE,SE and SY extracts showed inhibitory effect on the differentiation of preadipocyte 3T3-L1. The above results suggest that the TE,SE and SY extracts may be used on the obesity induced by the overgrowth and differentiation of adipocyte, and the accumulation of fat in liver and body.

Obesity is known as a metabolic disease caused by abnormal differentiation of fat tissue due to an imbalance between energy intake and consumption.. The purpose of this study was to confirm the changes in the genes associated with pancreatic lipase activity and pre-adipocyte cell differentiation by treatment of red onion extract treatment. The effect of red onion extract treatment on pre-adipocyte differentiation was evaluated using 3T3-L1 adipocytes, and the activity of related genes was confirmed through Real-Time PCR. As a result of the experiment, the red onion extract inhibit pancreatic lipidase activity by concentration dependent manner. In addition, it was found to inhibit adipocyte differentiation and inhibit the activity of genes(C/EBP-α, C/EBP-β, PPAR-γ) associated with adipocyte differentiation. Through the results of this experiment, it is suggested that the red onion extract can be developed as a high potential material with anti-obesity efficacy by suppressing adipocytic differentiation by controlling genes related to adipocyte differentiation.

Korean traditional herbs, especially Anemarrhena asphodeloides (A. asphodeloides), Salvia miltiorrhiza (S. miltiorrhiza), and Terminalia chebula (T. chebula) have been known to have the immunomodulatory, anti-tumor, and anti-inflammatory effects. However, direct cellular mechanism underlying the mast cell-mediated anaphylaxis-like reaction has poorly been understood. In the present study, the effects of the methanol extracts of A. asphodeloides (MEAA), S. miltiorrhiza (MESM), and T. chebula (METC) on anaphylactic reaction were investigated. Using in vitro and in vivo experiments, the influences of MEAA, MESM, and METC on the compound 48/80-induced anaphylaxis-like reaction and mast cell activation, and IgEmediated PCA were examined. Results are below; 1) MEAA, MESM, and METC significantly inhibited systemic anaphylaxis-like reaction, ear swelling response, and IgE-mediated PCA. 2) the compound 48/80-induced mast cell degranulation, histamine release of rat peritoneal mast cells (RPMC) were significantly inhibited by the pretreatment with MEAA, MESM, and METC, and 3) the compound 48/80-induced calcium influx in RPMC was significantly inhibited by the pretreatment with MEAA, MESM, and METC. These results suggest that MEAA, MESM, and METC may be an activity to inhibit the compound 48/80-induced or anti-DNP IgE-mediated anaphylactic reactions by blocking histamine release and calcium uptake into RPMC. MEAA, MESM, and METC potentially may serve as an effective therapeutic tool for allergic diseases.

The present study was conducted to evaluate the effects of various extracts of Hizikia fusiforme on the anti-obesity effects in 3T3-L1 preadipocytes. We used H. fusiforme extracts from ethanol (EEHF), dichloromethane (CFHF), ethyl acetate (EAFHF), butanol (BFHF), and water (WFHF). Treatment with these extracts significantly suppressed terminal differentiation of 3T3-L1 preadipocytes in a dose-dependent manner as confirmed by a decrease in lipid droplet content through Oil Red O staining; this effect was higher in WFHF than in other extracts. The concentrations of cellular triglyceride were also reduced in 3T3-L1 cells by exposure with these extracts, especially when compared with the controls. Treatment with 200 ${\mu}g/ml$ of WFHF and CFHF caused approximately 42.6% and 23.7% reduction, respectively. In addition, the extracts of H. fusiforme significantly reduced the expression levels of key pro-adipogenic transcription factors, including peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) and CCAAT/enhancer binding proteins ${\alpha}$ (C/$EBP{\alpha}$) and C/$EBP{\beta}$ as compared with controls. Accordingly, our data indicated that WFHF has a preeminent effect on inhibition of adipocyte differentiation among various extracts, and H. fusiforme extracts may be an ideal candidate for obesity relief.
