  • Objective : The purpose of this study was to investigate the anti-obesity and anti-hyperlipidemic Effects of Taeyeumjowee-tang and its modified prescription on the animal model of obesity and hyperlipidemia induced high-fat diet. Method : 1) The extracts of Taeyeumjowee-tang (TJT) and its modified prescription, Taeyeumjoweetang gagam-bang (TJGB) were evaluated for its inhibitory effects on obesity. 2) The body weight and feed weight were determined in the pre-treated and post-treated mice and the lipid profiles in the serum were analyzed in order to evaluate the anti-hyperlipidemia action of the extracts. 3) The effect of each extract was investigated for the influences on monoamine oxidase activity and HMG-CoA reductase activity. Results 1. TJT and TJGB extracts dose-dependently reduced the body weight and feed intake in normal mice. The effect of TJGB extract was better than that of TJT extract. 2. TJGB extract diminished the body weight increase and reduced the feed intake in the pre-treatment or post-treatment of the extract 3. TJGB extract decreased the amount of total cholesterol slightly and triglyceride potently after the pre-treatment or post-treatment, but HDL cholesterol exhibited no remarkable change compared with control. 4. TJGB extract weakly potentiated the monoamine oxidase activity, but its effect was better than that of TJT extract. 5. TJGB extract weakly inhibited the HMG-CoA reductase activity, but its effect was better than that of TJT extract. Conclusion : Taeyeumjowee-tang and its modified prescription can clinically be useful as anti-obesity drug and also for the improvement of hyperlipidemia.

  • In this study, we investigated the effects of fasting on gut microbiota of mice fed normal (CTL) or high-fat diets (HF). Mice were raised for 16 weeks and fasted for a day at the end of the experiment. Fecal samples were collected one day before and after fasting, which were analyzed using MiSeq. Our results showed that the species richness and evenness were decreased in fasted HF group, whereas no difference was observed for CTL groups. Moreover, HF fed mice gut microbiota showed different microbial communities after fasting, while CTL groups did not show microbiota shifts. Differential abundance analysis showed that fasting CTL group mice increased and decreased one operational taxonomic unit (OTU) in S24_7 and one OTU in Ruminococcaceae, respectively. On the other hand, fasting HF group mice decreased 10 OTUs and increased 3 OTUs most of which were classified to Ruminococcaceae. Our results suggest that fasting mice may affect the abundance of Ruminococcaceae species and effects of fasting seem to be more obvious for HF-fed mice compared to those of mice fed CTL-diet.

  • Background: Ginsenoside compound-Mc1 (Mc1) is a member of the deglycosylated ginsenosides obtained from ginseng extract. Although several ginsenosides have a cardioprotective effect, this has not been demonstrated in ginsenoside Mc1. Methods: We treated H9c2 cells with hydrogen peroxide (H2O2) and ginsenoside Mc1 to evaluate the antioxidant effects of Mc1. The levels of antioxidant molecules, catalase, and superoxide dismutase 2 (SOD2) were measured, and cell viability was determined using the Bcl2-associated X protein (Bax):B-cell lymphoma-extra large ratio, a cytotoxicity assay, and flow cytometry. We generated mice with high-fat diet (HFD)-induced obesity using ginsenoside Mc1 and assessed their heart tissues to evaluate the antioxidant effect and the fibrosis-reducing capability of ginsenoside Mc1. Results: Ginsenoside Mc1 significantly increased the level of phosphorylated AMP-activated protein kinase (AMPK) in the H9c2 cells. The expression levels of catalase and SOD2 increased significantly after treatment with ginsenoside Mc1, resulting in a decrease in the production of H2O2-mediated reactive oxygen species. Treatment with ginsenoside Mc1 also significantly reduced the H2O2-mediated elevation of the Bax:Bcl2 ratio and the number of DNA-damaged cells, which was significantly attenuated by treatment with an AMPK inhibitor. Consistent with the in vitro data, ginsenoside Mc1 upregulated the levels of catalase and SOD2 and decreased the Bax:B-cell lymphoma-extra large ratio and caspase-3 activity in the heart tissues of HFD-induced obese mice, resulting in reduced collagen deposition. Conclusion: Ginsenoside Mc1 decreases oxidative stress and increases cell viability in H9c2 cells and the heart tissue isolated from HFD-fed mice via an AMPK-dependent mechanism, suggesting its potential as a novel therapeutic agent for oxidative stress-related cardiac diseases.

  • An in vitro study was conducted to examine the effects of the addition of activated charcoal (AC) on the ruminal fermentation characteristics, nutrient disappearance, and ruminal gas production. AC was added at the levels of 0.00, 0.25, and 0.50 % to each of the four types of diets (roughage/concentrate ratio : 8/2, 6/4, 4/6 and 2/8), respectively. Although not significant, ruminal pH tended to increase by adding AC, and as the concentrate level increased, ruminal pH decreased (P<0.05). Acetate concentration and acetate/propionate molar ratio tended to decrease in AC diets. but molar % of propionate tended to increase by the addition of AC. Ruminal degradation of dry matter, crude protein, NDF, ADF, and hemicellulose in AC diets tended to increase than in non-AC diet, however, no tendency in ruminal degradation of crude fat was observed. As the concentrate level increased, rumunal degradation of dry matter and nutrients in AC diets increased significantly(P<0.05). Ruminal gas production tended to decrease in the 0.50 % AC diets, however, it tended to increase in high roughage diets. Although there appeared some beneficial effects in adding AC to ruminant diets in this study, more works should be done with AC before we can make clear conclusion on the use of AC in the ruminant diets.

  • The Mongolian ger is ideally suited to the mongol's steppe climate and the nomadic way of life. This is a multipurpose dwelling which can be easily collapsed, transported to another place and put up again fully preserving its original shape. The pastoral nomadic ger has two key components: the wooden framework and the felt cover. The wooden parts are the walls(khana), the long poles(un), the smoke escape(toono) and its supports(bagana). One wall consists of 10-15 branches of willow tree. each about 1.5m high bound together in a way making it possible to fold it for transportation and then unfold it like an accordion. The unfolded walls are connected to form a circle. The long poles(un) are fastened to the upper part of the walls, with the other end passed through the toono hole, the only sky window and smoke escape through it from the ger. The toono is propped up by two posts, called bagana. All this forms the wooden framework of the ger, which is covered with felt. When the herders fire up their metal stoves, the temperature inside the ger becomes quite comfortable. Because the nomads live in a climate where there is only one growing season in a year, they do not make long migrations to new pastures. Livestock subsist on standing vegetation for eight months of the year. The basic pasture migration strategy is to leave enough standing vegetation at the end of the growing season in September to suffice until the new growth appears the following May. Mongolians use a type of compressed tea leaf that is called "brick" tea in English because it is rock solid and roughly the shape of a brick. And they consume a larger percent(88%) of fat from animal products such as meat, milk, butter, and cheese than any other people in the world. Milk products made from the milk of sheep, yak, and goats are major foods in the nomad's diet, but they are produced mainly in summer when all the animals are lactating. Mongolians made their special nomadic food culture on the steppe.

  • Betaine functions as an osmoregulators in the cells and its inclusion in diet can spare the choline and carcass fat reduction in chicken. Thus, two hundred eighty eight laying hens were fed with 0, 500, 1,000, 2,000 ppm of betaine from seventy eight to eighty six weeks of age during the environmentally high temperature stress. Com and soybean basal diets contained 2,800 kcal/kg ME and 16% CP. Egg production, feed intake, and feed conversion were examined for eight weeks. Egg quality characters, serum cholesterol, liver betaine, and lower ileal osmolality were measured at the end of experiment. Egg Production rates of hens fed with 500 or 2,000 ppm of betaine were 75.06 and 75.02%, respectively and tended to increase compared to the control. The feed conversion(FCR) of these treatments was significantly(P<0.05) improved compared to that of control although it did not significantly differ in the e99 Production rates between 500 and 2,000 ppm of betain groups. Eggshell breaking strength of hens fed betaine was significantly(P<0.05) higher than those of control. However, betaine supplements did not influence to improving the albumen height and Haugh unit. Liver betaine in hens fed with betaine was linearly increased unto 2,000 ppm. The birds fed with 2,000 ppm betaine showed significantly(P<0.05) higher in the liver betaine than the control birds. Total cholesterol and triglyceride tended to be increased by dietary betaine supplement. The lower ileal osmolality in betaine supplement group tended to be slightly decreased. As a result, dietary betaine supplement tended to improve the egg Production and eggshell Quality in laying hens during heat stress.

  • Objectives We evaluated the improving effects of Taeksa-tang (TST) using 3T3-L1 cells and C57BL/6 mice were fed on a high-fat diet. Methods The anti-radical activities of TST were studied using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The content of total polyphenol was measured using Folin-Ciocalteu reagent, whereas aluminum chloride colorimetric method was used for the content of total flavonoid. Moreover, the factors related to lipid profile and the protein expressions such as 𝛽-oxidation and anti-oxidant enzyme were analyzed using serum and western blotting of 3T3-L1 cells. Additionally, we examined lipolysis through glycerol appearance in mouse adipose tissue. Results TST treatment showed strong free radical scavenging activities with half maximal inhibitory concentration and the presence of a amount of total polyphenol and total flavonoid. TST treatment significantly increased factors related to 𝛽-oxidation such as carnitine palmitoyl transferase-1 and uncoupling protein 2 via the phosphorlyation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK). Moreover, the protein expressions of anti-oxidant enzyme and lipolysis were significantly elevated by TST administration. In addition, TST supplementation lowered serum malondialdehyde, triglyceride, and total cholesterol levels compared with the control group. Taken together, these data suggest that TST treatment regulated lipid parameters via the increase of 𝛽-oxidation by LKB1-AMPK signaling pathway. Conclusions TST may have a potential remedy in the prevention and treatment of obesity. Therefore, this study may provide the scientific basis for TST use.

  • Objectives: The purpose of this study was to investigate the food, nutrient intake, and diet quality of postmenopausal women at high risk of osteoporosis (OP) and cardiovascular disease (CVD) compared with those of control subjects. Methods: A total of 1,131 post-menopausal women aged over 45 years, who took the 2010-2011 Korean National Health and Nutrition Examination Survey (KNHANES), were included for analysis. These participants were classified into the following groups: the OP group, with a risk of OP (n=135); the CVD group, with a risk of CVD (n=373); the OP+CVD group, with a risk of OP and CVD concurrently (n=218); and the control group (n=405) according to bone mineral density (BMD) and CVD risk. Anthropometric measurements, blood profiles, dietary intake, and dietary quality indices were measured and compared among the four groups. Results: Waist circumference, total body fat percentage, blood pressure, fasting plasma glucose, total cholesterol, triglyceride, and LDL-cholesterol were higher, and HDL-cholesterol and BMD were lower in the OP+CVD group than in the control group. In the food frequency questionnaire, the OP+CVD group had significantly higher frequencies of grain (except for multi-grain) and lower frequencies of fruit and dairy product. The frequency of consumption of red meat, processed meat, and carbonated beverages was higher in OP+CVD group. In nutrient density analysis, proteins and vitamin $B_2$ levels were significantly lower in the OP+CVD group than in the control group. The nutritional quality index (INQ) values of calcium were in the order of 0.63, 0.58, 0.56, and 0.55 in each group, and it was urgent to improve the dietary intake for calcium in postmenopausal women. In addition, vitamin $B_2$ was inadequately consumed by all groups. Conclusions: These results suggest that it is necessary to increase the intake of vitamin $B_2$ and calcium and decrease the frequency of intake of red meat, processed meat, and carbonated beverages in postmenopausal women with the risk of OP and CVD.

  • Little is known about the effects of the plane of nutrition on growth performance and meat quality of grow-finish pigs under commercial production conditions. The present study was thus addressed to this virtually unanswered question. One hundred and two barrows and 102 gilts weighing approximately 24 kg were fed phase I and II grower diets with a high, medium, or low plane of nutrition (HP, MP, or LP) to approximately 43 and 70 kg, respectively, in 6 replicates (pens). Subsequently, the HP and MP groups were fed the HP and MP1 finisher diets, respectively, the LP group being fed a second MP (MP2) finisher diet (LP1 group). Moreover, 68 LP-grower-fed barrows and gilts were added to the feeding trial and fed the MP1 and LP finisher diets to approximately 95 kg and thereafter, respectively (LP2 group). All MP diets had the lysine:calorie ratios comparable to the RNC recommendations, with < 18% differences between those of the HP and LP diets. The finisher pigs were reared in 16 pens and slaughtered at approximately 115 kg. The gain:feed ratio, but not average daily gain (ADG), was greater for the HP group than for the MP and LP during the grower phase I whereas during the grower phase II, ADG was greater (p < 0.05) for the HP and LP groups vs. MP. During the finisher phase I, ADG was less for the LP (LP1 + LP2) group vs. HP and MP, with no difference between the HP and MP groups; the gain:feed ratio was less for the LP vs. MP group. Backfat thickness was greater for the LP vs. HP group. The water holding capacity of fresh longissimus dorsi muscle (LM) and the sensory juiciness score for cooked LM were greatest for the LP group, the sensory flavor and tenderness scores being greater for the LP group vs. MP. In conclusion, results suggest that compensatory growth occurred for the LP and MP groups during the grower phase II and finisher phase I, respectively, with fat deposition increased for the LP group and that meat quality could be improved by the use of LP.

  • The objective of this study was to verify the stability of nutrient composition by using herbal medicine by-products as an alternative food source and to examine the growth effect on Protaeria brevitarsis seulensis larvae. As a result of comparing the nutritional components of food source, crude protein, crude fat, and crude ash content, except crude fiber content, was high in both non-fermented and fermented medicinal herbal by-products. Especially, crude protein content was highest. Cadmium, lead, mercury, and other heavy metals were not detected and thus stability as alternative food was confirmed. The growth comparison based on the feeding sources showed no significant difference between the fermented oak sawdust fed control group and the herbal medicine by-products fed laboratory group from week 1 to week 3. The weight of a 4 week larva was 0.137 g in the control group and 0.671 g in the laboratory group and so began to reveal differences at a significant level (p<0.05). As a result of comparing weights of Protaetia brevitarsis seulensis larvae according to the level of herbal medicine by-product addition, HMB40 recorded the heaviest weight in week 7. Statistical analysis showed that there was no significant difference in each body weights of HMB40 and HMB80 at week 5 (p<0.05). These results indicate that if the shipping date of an edible insect is a third instar larva, it arrives at the time of shipment at week 5. Thus feeding HMB40 and HMB80 at the 5th week is the most effective.
