Obesity is the leading metabolic disease in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and cancer. The objective of this study was to evaluate the anti-adipogenic effects of two roasted coffee beans, Vietnam robusta (VR) and Ethiopia Mocha Sidamo G2 (ES), as well as fermented coffee beans with Monascus ruber (MR) mycelium on differentiation of 3T3-L1 preadipocytes. Treatments with 1,000 ${\mu}g/mL$ of hot water extract from coffee beans significantly reduced intracellular lipid accumulation. In addition, VR more effectively inhibited transcription factors such as $PPAR{\gamma}$, $C/EBP{\alpha}$, FAS, and aP2 compared to ES. Further, ES fermented with MR showed more effective anti-adipogenic activity than non-fermented ES. These results suggest that VR and ES inhibit adipocyte differentiation which may contribute to their anti-adipogenic properties.

Sleep deprivation is an extremely common event in today's society. It has caused learning cognitive skill deterioration and poor concentration, increased disease such as heart disease, diabetes and obesity, sexual function decrease, infertility increase, depression and autonomic nervous system disorder. Sleep deprivation-induced stress caused NADPH oxidase and oxidative stress. And this oxidative stress induces apoptosis. Lilii bulbus and Nelumbins semen are known to mental and physical relaxation effects. In this study, we induced sleep deprivation(SD) in Sprague-Dawley rats in water for 5 days and thereafter administered orally L. bulbus and N. semen for 5 days. Brain tissues were observed by histochemical, immunohistochemical and tunel staining. The immunoreactives of Tumor necrosis factor ${\alpha}$, Neuronal nitric oxide synthases, Phospho-SAPK/JNK and gp91-phox of the L. bulbus administered group and N. semen administered group were weaker than those of sleep deprivation group. In the L. bulbus administered group and N. semen administered group, apoptosis was decreased than that of sleep deprivation group. Proapoptotic p53, Bax, Cleaved caspase 3 immunoreactives of the administered group were weaker than those of sleep deprivation group, whereas anti-apoptotic Bcl-2 immunoreactity was stronger in the L. bulbus administered group and N. semen administered group. Antioxidant mechanism such as DJ-1, superoxide dismutase 1, Nuclear factor-like 2 immunoreactives of the L. bulbus and N. semen administered group were stronger than those of sleep deprivation group. These results demonstrate that L. bulbus, N. semen had the neuroprotective effects on the sleep deprivation-induced oxidative stress in the hippocampus.

In the present study, we investigated the effect of 70% EtOH extract from Hippophae Rhamnoides L. leaves (HRL) on the anti-obesity effect in 3T3-L1 cells. The effects of HRL on lipid accumulation in 3T3-L1 cells were examined using Oil Red O staining. In addition, we examined the gene expression levels by using RT-PCR and western blot. The results of this analysis showed that 100 ㎍/㎖ HRL significantly increased the inhibition of lipid accumulation by 82.25%; significantly decreased the mRNA expression of sterol regulatory element binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding proteins α (C/EBPα), and fatty acid synthase (FAS) in 3T3-L1 cells as well as the stimulated protein expression of AMP-activated protein kinase (AMPK); and suppressed the expression level of PPARγ. These results suggest that HRL can prevent adipogenesis through activation of AMPKα and inhibition of adipogenesis transcription factors.

In recent year, We are concerned about anti-aging, disease-prevention, longevity, so many methods are used in solving this problem. And Those are related with antioxidative ability. Recently, We heard that Mori Cortex was known to reduce the hypertension and was helpful in promoting health, and Mori Ramulus was effective against obesity, etc. So, This study was performed to investigate the antioxidative effect of hot-water extracts of Mori Cortex and Mori Ramulus used for 3 methods, those are DPPH radical scavenging activity, Nitric oxide(NO) radical scavenging activity and Bovine serum albumin(BSA). And we compared Mori Cortex and Mori Ramulus on Antioxidative Effects. The results of this study were as follows: We measured levels of DPPH radical scavenging activity and Nitric oxide(NO) radical scavenging activity. And we obtained results that Mori Ramulus was most effective with the concentration of 5 $mg/m{\ell}$, and Mori Cortex was most effective with the concentration of 2.5 $mg/m{\ell}$, And we examined the antioxidative effects of Mori Ramulus and Mori Cortex with $CU^{2+}/H_20_2$-induced Bovine serum albumin(BSA). And we obtained that antioxidative ability was increased after 1.25 $mg/m{\ell}$ and that was most effective with the concentration of 5 $mg/m{\ell}$ on both of them. And antioxidative ability of Mori Cortex was better than Mori Ramulus(p<0.05). So I guess that hot-water extracts of Mori Ramulus and Mori Cortex have effects on antioxidative ability, but Mori Cortex is better than Mori Ramulus on antioxidation. Hereafter we need differential experimental methods of antioxidative effect on both of them.

Baek-kimchi (whitish baechu kimchi) was evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20 %) diet, and compared to the similar effects of baechu kimchi. Baek-kimchi does not use red pepper powder but contains higher levels of sliced radish and pear than baechu kimchi. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or HFD containing 5 % baek-kimchi or 5 % baechu kimchi. Feed consumption was not different among the groups, but weight gains were significantly lower in the groups fed either the normal diet or HFD with baek-kimchi or baechu kimchi diets than the group fed HFD alone. The weights of liver and epididymal and perirenal fat pads in baek-kimchi and baechu kimchi diet groups were lower than those of the HFD groups, but the baek-kimchi diet group had lower epididymal and perirenal fat pad weights than the baechu kimchi diet group (p<0.05). The baechu kimchi dietary group also had significantly lower triglyceride and cholesterol contents in liver and epididymal and perirenal fat, reversing the higher levels seen in HFD. Baek-kimchi and baechu kimchi diets were also effective in lowering serum triglyceride and cholesterol levels (p<0.05). These results suggest that baek-kimchi and baechu kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that baek-kimchi is more effective than baechu kimchi. The greater effect is probably due to the higher content of radish and pear used in baek-kimchi.

Aster Yomena (AY) has been used in traditional medicine to treat diseases such as obesity, hyperlipidemia, atherosclerosis, diabetes and osteoarthritis. However, protective effect of AY on acute pancreatitis (AP) has not been reported. The present study examined the anti-inflammatory effects of an ethanol extract of AY on cerulein-induced AP. AP was induced in mice by intraperitoneally injecting cerulein ($50{\mu}g/kg$) hourly for 6 times. 70% ethanol extract of AY (0.1, 0.2, and 0.5 g/kg) was orally administered for 1 week before acute pancreatitis induction. The mouse was killed at 6 hours after the final cerulein injection. The pancreas and lung were rapidly removed for histological examination and myeloperoxidase (MPO) assay. Blood samples were taken to determine serum amylase and lipase activity. In addition real-time reverse transcription-polymerase chain reaction (RT-PCR) was also performed to investigate mRNA expression of proinflammatory cytokines such as $TNF-{\alpha}$. $IL-1{\beta}$, and IL-6. Administration of AY significantly ameliorated pancreatic weight to body weight ratio, histological damages and MPO activity during AP. In addition, AY inhibited the serum amylase and lipase activity during AP. Also, mRNA expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 were inhibited by AY against AP. Our results revealed that pre-treatment of AY reduces the severity of cerulein-induced AP. Therefore, AY may have a protective effect drug against AP.

Objectives : In this study, the inhibitory activities of Korean Medicine against pancreatic lipase in vitro and biochemical analyses in vivo were measured to determine its possibility as a well-matched sauce material with chicken. Methods : The inhibitory activity on pancreatic lipase enzyme of 11 samples were evaluated in vitro and then 5 samples were selected. The activity of pancreatic lipase was investigated using orlistat as a positive control. Animals were divided into eight groups (n=7). The experimental groups except for normal group were fed 60% high-fat diet for 7 days. 5 samples were orally administered at a dose of 200 mg/kg body weight and orlistat were orally administrated at a dose of 60 mg/kg body weight for 7 days. Biochemical anaylses of 5 samples were executed based on lipid parameters analysis. Results : Korean Medicines with an $IC_{50}$ of below 1 mg/kg were Scutellariae Radix, Gardeniae Fructus, Theae Folium Coptidis Radix, and Mori Cortex Radicis. Body weight change of Mori Cortex Radicis reduced significantly, however fecal triglyceride couldn't regulate effectively. The most excellent inhibitory effect of pancreatic lipase showed in Scutellariae Radix treatment and also regulated significantly serum triglyceride and total cholesterol. Moreover, the supplementation of Coptidis Radix excreted meaningfully triglyceride to fece. Conclusions : In conclusion, Coptidis Radix may exert anti-obesity effect by directly inhibiting pancreatic lipase, which would prevent the absorption of lipid from the small intestine. Besides, Mori Cortex Radicis may led to the decrease of the body weight via the different pathway.

Background: Nonalcoholic fatty liver disease (NAFLD) is characterized by an increase in hepatic triglyceride content and increased inflammatory macrophage infiltration through the C-C motif chemokine receptor (CCR) 5 pathway in the liver. DA-6034 (7-carboxymethyloxy-3',4',5-trimethoxy flavone), is a synthetic derivative of eupatilin that exhibits anti-inflammatory activity in inflammatory bowel disease. However, the effect of DA-6034 on the inflammatory response in NAFLD is not well elucidated. Therefore, we aimed to determine the effect of DA-6034 on hepatic steatosis and inflammation. Methods: Forty male C57BL/6J mice were divided into the following four groups: (1) regular diet (RD), (2) RD with DA-6034, (3) high fat diet (HFD), and (4) HFD with DA-6034. All mice were sacrificed 12 weeks after the start of the experiment. The effects of DA-6034 on macrophages were assessed using RAW 264.7 cells. Results: DA-6034 not only reduced hepatic triglyceride levels and lipid accumulation but also macrophage infiltration and proinflammatory cytokines in HFD-fed mice. According to fluorescence-activated cell sorter analysis, DA-6034 reduced the CD8⁺ T cell fraction in the liver of HFD-fed mice. DA-6034 also reduced CCR5 expression and the migration of liver macrophages in HFD-fed mice and inhibited CCR2 ligand and CCR4 ligand, which stimulated the migration of macrophages. Conclusion: Overall, DA-6034 attenuates hepatic steatosis and inflammation in obesity by regulating CCR5 expression in macrophages.

Salicornia herbacea L. is an annual herb that grows in salt marshes and salt fields along the seashores. It is also commonly used as a folk remedy in Korea. The objective of this study was to investigate the beneficial effects of Salicorrnia herbacea L. (SH) hot water extract on obesity. Five-week old male Sprague-Dawley rats (n=36) were divided into two groups and provided either a normal fat diet (11.5% fat from kcal) or a high fat diet (40.5% fat from kcal) for 6 weeks to induce obesity. Then, rats were blocked into six groups of six mice each and provided either a diet containing SH (0.5% of diet; g/kg) or a normal diet for another 6 weeks. Final body weights were significantly reduced when rats were fed SH among the high fat diet groups (HNS and HHS). Serum triglyceride concentrations significantly decreased in every group provided SH. HDL-cholesterol concentrations significantly increased in SH-fed groups among the high fat diet groups. Further, atherogenic index significantly decreased when rats were fed SH diet (HHS). There were no differences in LDL-cholesterol between the high fat diet groups, and glucose concentrations decreased when rats were fed SH diet (HNS). These results indicate that dietary intake of Salicornia herbacea L. hot water extract might have beneficial effects on obesity by reducing body weight, fat weights, and improving blood lipid profile.

Agaricus blazei Murill (Almond mushroom) has many beneficial effects, such as anti-cancer, immuneenhancement, and anti-obesity. Also, its skin benefits have been reported for antioxidant, anti-inflammatory, and whitening. In order to elucidate these effects, many studies have been conducted. In this study, we reconfirmed the skin efficacy of the extract of the mushrooms mushrooms. The Agaricus blazei extract showed inhibition of melanin synthesis, enhancement of collagen synthesis, and up-regulation of gene expression (hyaluronan syntahase-2, 3 and aquaporin-3) at 100 ㎍/mL. and identified the ingredients from the extract. We further investigated them to find an applicability as cosmetic ingredients. The ingredients were confirmed comparison of their spectroscopic data with literature values. They were identified as being ergosterol (1), 5-dihydroergosterol (2), cerevisterol (3), cerebroside B (4), cerebroside D (5), adenosine (6), and benzoic acid (7). Among these compounds, we evaluated skin efficacy for two cerebrosides and three ergosterol derivatives that have not been reported its efficacy. As a result, 5-dihydroergosterol (2) inhibited melanogenesis in B16F10 and promoted collagen biosynthesis in human dermal fibroblast. In addition, cerevisterol (3), cerebroside B (4), and cerebroside D (5) inhibited NO production in RAW 264.7 cell. In particular, cerebroside D (5) increased the expression of hyaluronan synthase-2 and aquaporin-3 genes in HaCaT. These results suggest that Agaricus blazei extract and isolated compounds can be used as cosmetic ingredients.
