  • Objectives: The object of this study was to observe the complex anti-climacterium potentials of Yuklinzu aqueous extracts (YLZ), using bilateral ovariectomy (OVX) female ddY mice similar to women postmenopausal symptoms, as including cardiovascular diseases, obesity, hyperlipidemia, osteoporosis and hepatic steatosis. Methods: In order to evaluate anti-climacterium effects of YLZ, six groups of mice were used; sham control, OVX control, 17β-estradiol, YLZ 500, 250 and 125 mg/kg treated groups. Since 28 days after bilateral OVX surgery, YLZ were administered orally for 84 days, once a day. And then we evaluated anti-climacterium effects divided into five categories; estrogenic effects, anti-obesity, hypolipidemic effects, hepatoprotective effects and anti-osteoporotic effects. The results of YLZ were compared with 17β-estradiol 0.03 ㎍/head/day subcutaneous treated OVX mice. Results: As a result of OVX, obvious changes related to the estrogen-deficient menopausal symptoms - obesity, hyperlipidemia, hepatic steatosis and osteoporosis were displayed in mice. However, these menopausal symptoms induced by OVX were significantly inhibited by 84 days of consecutive treatment of 17β-estradiol, YLZ 500, 250 and 125 mg/kg, respectively. Especially, YLZ showed obvious dose-dependent inhibitory activities on the OVX-induced climacterium changes in mice, and YLZ 500 mg/kg showed comparable inhibitory effects against menopausal symptoms in comparison with those of 17β-estradiol 0.03 ㎍/head/day subcutaneous treatment. Conclusions: The results suggest that oral administration of YLZ 500, 250 and 125 mg/kg has obvious dose-dependent favorable anti-climacterium effects in OVX mice. Especially, YLZ 500 mg/kg showed comparable inhibitory effects against menopausal symptoms in comparison with those of 17β-estradiol 0.03 ㎍/head/day subcutaneous treatment.

  • In relation to the global increase trend of obesity population, there is a demand for the development of foods having high functional activity by mass-extracting anti-obesity active substances using mulberry product such as leaf and fruit. Therefore, we evaluated the antiobesity efficacy according to varieties by using the mulberry leaves and fruit extracts. At the same time, high active varieties were selected. For this purpose, the effects of the extracts of the mulberry leaf and fruit on 3T3-L1 adipocyte differentiation were examined. As a result, in the case of mulberry leaves, the lipid accumulation inhibitory rate of 'Cheongolppong' was higher than that of the control at $500{\mu}g/ml$ treatment. And in the case of the extract of mulberry fruit, 'Daesim' showed the highest lipid accumulation inhibitory rate compared with the control at 50 times of diluted extract.

  • Anti-obesity effect of biocellulose and diet formulation containing it was evaluated using obese rats. Thirty male Sprague-Dawlely (SD) rats were randomly assigned to high-fat diet group (CON), high-fat diet group containing 5% biocellulose (BIO), and high-fat diet group containing 5% dietary formulation (DF). After 10 weeks, body weight gains of BIO and DF groups were reduced by 15.1 and 6%, respectively, as compared with CON group. Epididymus, parirenal, and visceral fat pads of BIO and DF groups were lower than those of CON group. Weight of interscapular brown adipose tissues increased slightly in BIO group and significantly in DF group. Size of adipocyte in rats decreased in BIO and DF groups. Results indicate biocellulose-containing diet has anti-obesity effect by reducing body weight gain and white adipocytes depots in rats fed high-fat diet.

  • In this study, we investigated the in vitro anti-obesity, anti-cancer activity and single oral dose toxicity of Inonotus xeranticus extracted by methanol (INXM) or ethyl acetate (INXE). In order to investigate anti-obestity effect of Inonotus xeranticus extracts, the 3T3-L1 cells were treated with these extracts at various concentrations(1, 10, 100 and $300{\mu}g/ml$). It was observed that 3T3-L1 cells treated with $100{\mu}g/ml$ of Inonotus obliquus ethyl acetate extract (INOE), INXM and INXE, in the absence of differentiation cocktail (0.5mM isobutylmethylxanthine (IBMX) $1{\mu}M$ dexamethasone, $1{\mu}M$ insulin), differentiated at a rate of 78.5, 80.9, and 76.4% respectively. Differentiation rates of 86.6% and 83.4% were observed in 3T3-L1 cells which were treated with differentiation cocktail at $100{\mu}g/ml$ of INXM and INXE, respectively. The anti-cancer effect of Inonotus xeranticus extracts was investigated using a method of sulforhodamine B in sarcoma 180 cell line. The cells were treated with these extracts (1, 10, 100 and $300{\mu}g/ml$) for 48 hours. The growth of cells which were treated with $300{\mu}g/ml$ of INXM was inhibited by 80.1%. The growth of sarcoma 180 cells which were treated with 100 and $300{\mu}g/ml$ of INXE was inhibited by 74.7% and 64.5%, respectively. In single oral dose toxicity study, no differences were observed between control and treated groups in clinical signs, body weight gains, and feed and water consumptions. The results indicated that Inonotus xeranticus extracts did not show any toxic effects at 2,000mg/kg in mice, and the $LD_{50}$ of these extracts was found to be higher than 2,000 mg/kg in this experiment. From the above results, Inonotus xeranticus methanol and ethyl acetate extracts might have useful clinical applications in the management of cancer and obesity and may also be useful as a medicinal food.

  • In an effort to develop novel mushroom-derived anti-obesity nutraceuticals, water and ethanol extracts containing the lipaseinhibitory compound from Phellinus linteus were prepared, and their nutritional components were determined. The optimal conditions for the extraction of P. linteus lipase inhibitor involved the treatment of the fruiting bodies with distilled water at $80^{\circ}C$ for 72 hr and 80% ethanol at $100^{\circ}C$ for 60 hr, respectively. The distilled water extract and ethanol extract contained 10.9% and 6.11% of crude protein, and 0.96% and 15.86% of crude fat, respectively. Additionally, the distilled water extract contained a large quantity of minerals, including 239.5 mg of K, 39.3 mg of Mg, and 39.3 mg of Na. The free amino acid content of the distilled water extracts was also higher than that of the ethanol extracts, and in particular, the distilled water extracts contained 5,139 mg of asparagine, 3,891 mg of tryptophan, 2,598 mg of alanine, and 2,066 mg of serine in 100 g of the distilled water extracts. 100 g of the distilled water and ethanol extracts were found to contain 12.31 g and 8.16 g of malic acid, respectively.

  • Using high-fat diet-induced obese (DIO) mice, the mechanism of anti-adiposity and anti-obesity actions produced by Inonotus obliquus water extract (IOE) was investigated. Significant reduction in body weight in DIO mice orally administrated with IOE for 8 weeks compared to IOE-non-treated control mice was observed, which was attributed to the reduction of epididymal and mesenteric adipose tissue, but not the liver and skeletal muscle. Adiponectin synthesis in epididymal adipose tissue (EAT) and AMPK phosphorylation in the liver were significantly increased in IOE-treated DIO mice. Gene expression analysis showed that IOE-treated DIO mice had higher expression levels of lipogenic genes in EAT and fatty-acid oxidative genes in the liver, but lower expression levels of hepatic pro-inflammatory cytokines compared to IOE-non-treated controls. Our findings confirm a therapeutic potential of Inonotus obliquus for reducing adiposity and ameliorating hyperlipidemia to treat metabolic disorders.

  • The purpose of the present study was to investigate effects of kochujang and red pepper on energy intake, body fat content and energy expenditure in rats fed on high-fat(30%) diet. Kochujang and red pepper power were added in the high-fat diet, adjusting the level to 95 and 22g/kg diet, respectively, The level of red pepper addition was corresponding was corresponding to the level of the content of red pepper powder in the kichujang-added diet. Kochujang induced a 30% reduction in body fat gain which was associated with a significant increase in energy expenditure. However, red pepper reduced body fat gain by only 15%. Furthermore, energy expenditure was not affected by red pepper. Metabolizable energy intake, apparent digestibility and body protein gain were not affected by either kochujang or red pepper. It has been known that capsaicin, a pungent component of red pepper, enhances activity of brown adipose tissue through increasing protein content. In the present study, in addition of protein content, DNA content of interscapular brown adipose tissue was also increased by kochujang. Therefore, it appeared that the anti-obesity effects of kochujang was greater than those of red pepper, indicating more than red pepper was involved in the expression of the anti-obesity effects of kochujang(Korean J Nutrition 33(8) : 787-793, 2000)

  • Three kinds of bacteria that influence Kimchi fermentation, Lactobacillus plantarium for acidity, Leuconostoc mesenteroides for ripening Kimchi, and Pichia membranifaciens for decreasing Kimchi quality, were regulated by natural products including Theae folium, Taraxacum coreanum, Brassica juncea, Astragali radix, Gynostemma pentaphyllum, Camellia japonica, Agaricus blazei, and Cordyceps militaris. The common prescription combined T. folium, T. coreanum and C. militaris and simultaneously regulated these 3 bacteria as follows: the growth of L. plantarium and P. membranifaciens were inhibited and L. mesenteroides was promoted. The most effective mixing ratio was T. folium: T. coreanum: C. militaris = 3:2:1. With this new prescription, deep flavor, extended preservation, and a special taste are expected in the Kimchi due to these natural products.
