  • To investigate the effect of GyeongshinhaeGihwan 1(GGT1) frequently used as an anti-obesity herbal medicine in oriental medicine on the expression of obesity-related genes, we measured the changes in mRNA levels of these genes by GGT1 in human growth hormone transgenic (hGHTg) obese female rats, and these effects by GGT1 were compared with those of reductil (RD), an anti-obesity drug approved by FDA. Rats received once daily oral administrations of autoclaved water, RD, or GGT1 for 8 weeks. At the end of study, rats were sacrificed and tissues were harvested. Total RNA from adipose tissue, liver and kidney was prepared and the mRNA levels for LPL (lipoprotein lipase), $PPAR{\gamma}$ (peroxisome proliferator activated receptor-gamma), $PPAR{\delta}$ (peroxisome proliferator activated receptor-delta), leptin, $TNF{\alpha}$ (tumor necrosis factor-alpha), and internal standard G3PDH (glyceraldehyde-3-phosphate dehydrogenase) were analyzed by RT-PCR. Compared with control group, $PPAR{\gamma}$ mRNA levels of liver and kidney were decreased in both RD and GGT1 groups, and the effects were more prominent in GGT1 group than in RD group, suggesting that GGT1 is effective in the inhibition of lipid storage by decreasing the $PPAR{\gamma}$ expression. $PPAR{\delta}$ mRNA levels of adipose tissue were increased by RD and GGT1 compared with DW, and the magnitude of increase were higher in GGT1 group than in RD group, indicating that GGT1 stimulates fatty acid oxidation and energy metabolism by activating $PPAR{\delta}$ expression. GGT1 group had higher concentrations of serum leptin, a well-known inhibitor of appetite, than control and RD groups. However, The mRNA levels of leptin, LPL, and $TNF{\alpha}$ were not changed by GGT1. These results indicate that GGT1 can prevent obesity in hGHTg obese female rats by down-regulating and up-regulating the mRNA expression of $PPAR{\gamma}$ and $PPAR{\delta}$, respectively, and that this anti-obesity effects were more pronounced in GGT1 group compared with RD group. In addition, GGT1 seems to inhibit obesity by increasing the circulating leptin levels.

  • Effects of various combinations of corn oil (CO) and perilla oil (PO) as respective dietary sources of ${\omega}$-6 and ${\omega}$-3 polyunsaturated fatty acids on fatty acid profiles of immune organs were studied in young chicks. Seventy-five 1-day-old male (ISA Brown) chicks were assigned to five treatments with three replications. Semi-purified-type diets containing glucose and soybean meal as major ingredients were added with 8% CO, 6% CO+2% PO, 4% CO+4% PO, 2% CO+6% PO and 8% PO and fed for 7 weeks. There were no significant differences in body weight gain, feed intake and relative weights of liver and immune organs (g/100g weight) among dietary groups. Dietary fatty acid patterns were generally reflected in the fatty acid compositions of all immune organs such as spleen, thymus and bursa of Fabricius. The levels of a-linolenic acid(LNA), eicosapentaenoic acid (EPA) and docosahexaenoic acid in various immune organs increased with increasing levels of perilla oil in the diets, whilet the levels of linoleic acid (LA) and arachidonic acid (AA) decreased. Thymus appeared to have capacity to retain remarkably higher (P<0.05) levels of LA and LNA up to 37 and 22%, respectively, compared to the other organs. Thymic tissue contained ${\omega}$-3 fatty acid and ${\omega}$-6 fatty acid 10~36 times and 3~5 times higher than the other organs, respectively. Spleen tissue was specifically higher (P<0.05) in the levels of AA and EPA and the ratios of AA/LA and EPA/LNA, compared to the other organs, suggesting that the tissue might have high desaturase activity to convert LA or LNA to AA or EPA, respectively. BSA antibody production tended to increase by 18 ~ 32% with higher levels of perilla oil in diet, although the increase was not statistically significant. In conclusion, fatty acid compositions of immune organs very depending on the lipid composition of the diets and each organ appears to respond differently for its fatty acid profile to dietary lipids. Considering AA and EPA are precursors of many important eicosanoids, further studies are required to clarify the responses of the immune organs to the dietary fatty acids.

  • Hepatic disease has been noted and reported for involvement various detrimental factors. Among many detrimental injury factors, alcohol has been noted for hepatitis, fatty liver, fibrosis, and hepatic cirrhosis. The purpose of this study is to develop animal model for hepatic fibrosis in pig with ethanol, and to search new anti-fibrogenic agent. Twelve male Landrace pigs were divided into 3 groups of 4 animals each. Group 1, 2 and 3 were fed with ceramic water only, ceramic water + liquid diet containing 20% ethanol and normal tap water + containing 20% ethanol for 12 weeks, respectively. At week 12, all pigs were immediately sacrificed for collection each tissue and blood. Serologically, serum ALT and AST levels were significantly reversed in group 2, comparing to group 3. They were normal range in pigs of group 1. Microscopically, macrovesicular lipid droplets and moderate necrosis were evident in the tap water + ethanol fed group 3. However, ceramic water intake group 1 showed normal. Moreover, in group 3, little fatty changes and mild necrosis were observed. Collagen fibers were detected in the spaces of surrounding periportal and interlobular areas in the group 3 of tap water + ethanol, but collagen synthesis and its thickness of fibrotic septa connecting portal tracts was markedly reduced in the group 2 of ceramic water + ethanol. In immunohistochemistry, myofibroblasts were detected in the ethanol and tap water treated group 3. No or a few myofibroblasts were observed in groups 1 and 2. CYP 2E1 was rarely detected in group 1 fed ceramic water. However, group 2 showed slightly activation of CYP 2E1 in the area of pericentral, while CYP 2E1 was significantly activated in group 3 fed tap and ethanol. Taken together above, alcohol fibrosis model in pig was established. Furthermore, ceramic water had an inhibitory and protecting ability for alcohol-induced hepatic damages.

  • This study was carried out to estimate beneficial effects of Foeniculi fructus water extract on activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS), and hormone sensitive lipase (HSL) on lipid metabolism related with obesity. LPL and ACS were extracted from the epididymal adipose tissue and liver of C57BL/6J normal and obese mouse. Foeniculi fructus water extract treatment significantly reduced the activity of normal and obese LPL. When 100 ppm of Foeniculi fructus water extracts were tested, they decreased obese LPL activity by 12.0%. Foeniculi fructus water extract activated obese ACS activity by 7-fold compared with control at 1,000 ppm concentration. Expression of HSL mRNA was increased in Foeniculi fructus water extracts treated cells compared with non treated cells. All things considered, Foeniculi fructus water extract efficiently inhibits the influx of fatty acid into the cell, and activates metabolic process that uses fatty acids flowing as an energy source. Thus, it suggest that Foeniculi fructus water extract may have great potential as a novel anti-obesity agent.

  • Three experiment were designed to determine the effects of dietary(n-3) fatty acids on the growth-suppressive effects of the inflammatory response and anti-oxidant enzyme activity and balances of nitrogen and energy. Day-old chicks were fed diets containing 1.0 % soybean oil in experiment 1, or diets containing 1.0 % of fish oil in experiment 2, and then on 7-d of age chicks were fed diets containing 1.0 % of either soybean oil or fish oil. In experiment 3, day-old chicks were fed on diets containing 1.0 % of either soybean oil or fish oil. In chicks of half pens within each dietary treatments of each experiments, the acute phase response were induced by injecting with Salmonella typhymurium lipopolysaccaride(LPS) i.p. 3 times at 8, 10 and 12-d of age. During acute phase response, chicks fed dietary fish oil from 1-d of age enhanced energy balances and did not give negative effect on nitrogen balance and uric acid excretion, but elevated MnSOD and Cu/ZnSOD activity In liver and erythrocyte cytosols compared with those fed dietary soybean oil. The results indicated that enhanced daily gain and metabolizable energy value of diet in birds fed fish oil from one-d of age seems due to change on the antioxidants systems during acute phase response.

  • DA-11004 is a synthetic, potent NADP-dependent isocitrate dehydrogenase (IDPc) inhibitor where $IC_{50}$ for IDPc is 1.49 $\mu$M. The purpose of this study was to evaluate the effects of DA-11004 on the high fat high sucrose (HF)-induced obesity in male C57BL/6J mice. After completing a 8-week period of experimentation, the mice were sacrificed 1hr after the last DA-11004 treatment and their blood, liver, and adipose tissues (epididymal and retroperitoneal fat)were collected. There was a significant difference in the pattern of increasing body weight between the HF control and the DA-11004 group. In the DA-11004 (100 mg/kg) treated group the increase in body weight significantly declined and a content of epididymal fat and retroperitoneal fat was also significantly decreased as opposed to the HF control. DA-11004 (100 mg/kg) inhibited the IDPc activity, and thus, NADPH levels in plasma and the levels of free fatty acid (FFA) or glucose in plasma were less than the levels of the HF control group. In conclusion, DA-11004 inhibited the fatty acid synthesis in adipose tissues via IDPc inhibition, and it decreased the plasma glucose levels and FFA in HF diet-induced obesity of C57BL/6J mice.

  • Lindera erythrocarpa Makino (LE) is widely distributed on Jeju Island, where it has been used for various traditional therapies. Effects of a crude extract of LE were examined in rats with obesity induced by a high-fat diet (HFD). Anti-obesity effects were followed in rats receiving orally administered vehicle, 100mg/kg extract, or 250 mg/kg LE extract, for 56 days. LE extract (250 mg/kg) suppressed increases in body weight and epididymal fat, with amelioration of fatty changes in the liver. Additionally, serum levels of alanine aminotransferase, aspartate aminotransferase, and total cholesterol were significantly decreased compared with those of vehicle-treated groups (p < 0.05). These results suggest that oral administration of LE extract reduced rat obesity induced by HFD, possibly through the reduction of fat accumulation.

  • Betaine, a major component of Lycii Fructus, was evaluated for its anti-hepatotoxic activity on carbon tetrachloride-induced hepatotoxicity in primary cultured rat hepatocytes. Betaine was found to attenuate carbon tetrachloride-induced hepatotoxicity both morphologically and biochemically. Typical hepatocyte necrosis due to carbon tetrachloride seemed to be reduced by 50 to 500 $\mu{M}$ of betaine under microscopical observation. The value of glutamic pyruvic transaminase released from the hepatocytes into the medium significantly decreased as betaine concentration increased. Betaine also significantly elevated the reduced activities of some enzymes, cytochrome P-450, 7-ethoxycoumarin-0-deethylase and glutathione-S-transferase, involved in xenobiotic metabolism due to carbon tetrachloride-induced hepatotoxicity. These results demonstrate a possible hepato-protective role of betaine against fatty liver that could be easily induced by carbon tetrachloride.

  • Extracts from Geum japonicum (Bammu in Korean) were analyzed for their antioxidative activities and scavenging effects on free radicals. The ethyl acetate fraction of G. japonicum methanol extract (EFGJ) showed a remarkable scavenging activity on the 1,1-diphenyl-2-picrylhydrazyl radical. EFGJ also showed excellent antioxidative activity on linoleic acid during long-period storage and on rat liver microsome peroxidation system, and good anti-peroxidation effect on lipid in Rancimat system using lard, palm oil, and perilla oil, as compared with BHT and ${\alpha}$-tocopherol. Varying effects of antioxidative activity of the EFGJ on various fatty acids were observed. The prevention of linoleic acid and linolenic acid peroxidation was superior to ${\alpha}$-tocopherol, but inferior to BHT. The methanol extract of G. japonicum did not show mutagenicity as revealed through SOS chromotest. Based on the results, the extracts of G. japonicum may be useful source as natural antioxidants.

  • Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.
