  • In this study, we examined the inhibitory effect of L. plantarum Q180 on adipocyte differentiation in 3T3-L1 and reduction of adipocyte size in mice fed high-fat diet. L. plantarum Q180 inhibited the adipocyte differentiation of 3T3-L1 cells ($18.47{\pm}0.32%$) at a concentration of $400{\mu}g/mL$ ($10^8CFU/g$). As a result of western blot analysis, the expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ in 3T3-L1 adipocyte treated with $400{\mu}g/mL$ of L. plantarum Q180 decreased 35.16% and 40.07%, respectively, compared with the control. To examine the effects, mice were fed three different diets as follows: ND (n=6) was fed ND and orally administered saline solution; HFD (n=6), HFD and orally administered saline solution; and HFD+Q180 (n=6), HFD and orally administered L. plantarum Q180. After six weeks, the rate of increase of body weight was 13.7% lower in the HFD+Q180 group compared to the HFD group. In addition, the epididymal fat weights of the HFD+Q180 group were lower than that of the HFD group. The change of adipocyte size was measured in diet-induced obese mice. Consequently, the number of large-size adipose tissue was less distributed in the ND and HFD+Q180 groups than in the HFD group. L. plantarum Q180 has an effect on the inhibition of 3T3-L1 adipocyte differentiation, fat absorption and reduction of adipocyte size. L. plantarum Q180 could be applied to functional food products that help improve obesity.

  • We investigated the effects of a pulsed electric field (PEF) treatment on microbial inactivation and the physical properties of low-fat milk. Milk inoculated with Escherichia coli, Saccharomyces cerevisiae, or Lactobacillus brevis was supplied to a pilot-scale PEF treatment system at a flow rate of 30 L/h. Pulses with an electric field strength of 10 kV/cm and a pulse width of 30 µs were applied to the milk with total pulse energies of 50-250 kJ/L achieved by varying the pulse frequency. The inactivation curves of the test microorganisms were biphasic with an initial lag phase (or shoulder) followed by a phase of rapid inactivation. PEF treatments with a total pulse energy of 200 kJ/L resulted in a 4.5-log reduction in E. coli, a 4.4-log reduction in L. brevis, and a 6.0-log reduction in S. cerevisiae. Total pulse energies of 200 and 250 kJ/L resulted in greater than 5-log reductions in microbial counts in stored PEF-treated milk, and the growth of surviving microorganisms was slow during storage for 15 d at 4℃. PEF treatment did not change milk physical properties such as pH, color, or particle-size distribution (p<0.05). These results indicate that a relatively low electric-field strength of 10 kV/cm can be used to pasteurize low-fat milk.

  • The anti-obesity effects of yeast hydrolysate (YH) supplementation (1.0 g/d) have already been demonstrated. We investigated whether a low dose of YH (0.5 g/d, YH-500) also has the anti-obesity effects. Thirty obese women were randomly assigned to the control or YH-500 groups. After 8 weeks, weight and body mass index were significantly reduced by the YH treatment (0.5 g/d) (P<0.05). The YH-500 group lost a significant amount of body fat after the 8-week treatment: fat mass 25.9 kg (baseline) versus 23.8 kg (8th week), P<0.01; fat mass ratio 38.8% (baseline) versus 36.5% (8th week), P<0.05. The YH-500 group showed a significant reduction in calorie intake during the 8-week treatment (P<0.001). The control group wanted to eat much more food (P<0.05) and sometimes thought about eating more often compared with the YH-500 group (P<0.05). Whereas the control group showed a slightly increased sweet preference, the YH-500 group showed a significant reduction in sweet preference (P<0.05). In conclusion, low dose YH supplementation (0.5 g/d) may induce a reductions in weight and body fat in obese women via the reduction of calorie intake.

  • Background & Methods: In order to study the effect of electro-lipolysis-acupuncture, 57 outpatients who have had herbal medication in Kirin Oriental Hospital were devided to two groups; acupuncture-treated group(46) vs non-acupuncture-treated group(11) Acupuncture-treated group was given electro-lipolysis-acupuncture at least two times a week and administered with herbal diet medication, whereas non-acupuncture-treated group was administered only with herbal diet medication. Results: Mean age, body weight and BMI of these two group at the start point of the treatment were $27.22({\pm}7.64)\;vs \;29.09({\pm}8.73),\;67.76({\pm}9.34)\;vs\;67.00({\pm}10.69),\;and\;26.20({\pm}3.02)\;vs\;26.14({\pm}4.10)$ in the order of acupuncture-treated and non-acupuncture groups. After one month of treatment, change rate of body weight, BMI, total fat, percentage of fat was significantly higher in acupuncture-treated group. Also the change rate of arm circumference, hip circumference and thigh circumference was significantly higher in acupuncture-treated group. The change rate of abdominal circumference and WHR of acupuncture-treated group was higher than that of non-acupuncture-treated group with no statistical significance. The circumference reduction rate according to herbal dieting program was higher in this order, abdomen, arms, chest, thighs and hips. On the other hand, chest circumference change rate over weight loss rate, which is the portion no acupuncture treatment was given to, and AMC change rate was higher in non-acupuncture-treated group. Conclusion: These results imply that herbal dieting program combined with electro-lipolysis-acupuncture is more effective on reducing body fat, size reduction of localized obesity and preservation of muscle than herbal prescription only dieting program.

  • 유지방을 초임계 이산화탄소로 추출한 후 흡착제를 통과시켜 콜레스테롤이 제거되고, 지방산 조성이 다른 유지방 분획들을 얻기 위하여, 콜레스테롤 흡착능이 있는 것으로 알려진 몇 가지 흡착제를 선택하여, 추출온도 $40^{\circ}C$, 추출압력 276, 345 bar에서 3 또는 4시간 동안 추출하면서 흡착제의 종류별, 입자크기별, 비율별로 추출시간에 따른 유지방의 수율, 콜레스테롤 함량, 지방산 조성을 측정하였다. 흡착제로서 ${\beta}-cyclodextrin,\;talc,\;celite,\;florisil$ 중에서 florisil이 유지방으로부터 콜레스테롤 제거율이 가장 높았다. Florisil의 입자크기별로 콜레스테롤 제거율은 30/60 mesh가 가장 높았으며, 그 다음 100/200, 60/100 mesh순이었다. 유지방에 대하여 흡착제의 비율이 높으면 콜레스테롤 제거율은 높은 반면, 지방의 수율은 감소하였는데, 유지방의 수율을 높이면서 콜레스테롤 제거율을 높이기 위해서는 유지방과 흡착제의 비율은 20:10이 적당하였다. 추출분획물의 지방산 조성을 측정한 결과 저급 지방산들은 초기 추출물 분획들에 농축되었고, 고급 지방산들은 추출잔류물 분획에 농축되었다. 이상의 결과로부터 초임계유체 추출 및 흡착법은 유지방으로부터 콜레스테롤을 제거하는 동시에 저급지방산, 불포화지방산, 버터향, 색소가 농축된 분획 등을 얻을 수 있었다.

  • The present study was designed to evaluate the usefulness of Sauropus. androgynus leaf (SAL) meal on reducing fat accumulation in broiler chickens. Eighty unsexed broiler chickens were allocated to four treatment groups with five replicates of four chickens each. SAL meal supplementation had no effect on body, leg, back, breast, wing, liver and heart weights, carcass protein, moisture and ash contents (p>0.05). Broilers fed diets supplemented with 30 g of SAL meal had lower feed intake with better feed conversion ratio (p<0.05) than did the control chickens. SAL supplementation at all levels significantly reduced fat accumulation in abdomen region, and liver (p<0.01), and in carcass (p<0.05). Higher SAL supplementation resulted in lower fat accumulation in the carcass ($r^{2}=0.94$; p<0.01), abdomen ($r^{2}=0.99$; p<0.01) and liver ($r^{2}=0.98$; p<0.01). The current study showed that a 30 g supplementation of SAL meal to the broiler diet was effective to improve feed conversion ratio without reducing body weight. SAL meal supplementation to the diet reduce fat accumulation in broiler chickens.

  • 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)

  • Obesity is a global pandemic that is increasing throughout most of the world. Increases in obesity are not restricted to highly industrialized countries, but have been observed in newly developed and developing countries as well. Obesity is associated with increased risk for non-insulin dependent diabetes mellitus, coronary artery disease, and some types of cancer. Tragically, eliminating food shortages in developing countries may result in substituting heart disease, diabetes, and cancer for malnutrition. There are many approaches to reducing obesity, including dietary modification, surgical interventions, and drug therapies. However, only dietary modification has the potential to be effective on a global scale. Public health measures in the United States have sought to reduce obesity by reducing the intake of dietary fat. While these efforts have succeeded in reducing dietary fat, obesity has continued to increase, suggesting that moderate fat reduction may not be effective. Other proposed diets include low-carbohydrate diets, low glycemic index diets, and very low fat diets. While all of these diets may be effective for some people, they are not satisfactory for public health policy. In fact, the ratio of fat to carbohydrate may not be as important as previously believed. Humans may be well suited to adapt to diets as varied as a high carbohydrate tropical diet consisting mostly of fruits to the high fat Eskimo diet consisting largely of animal foods. Either extreme may be healthful if providing adequate, but not excessive, energy and adequate amounts of micronutrients. Public health measures may need to focuss on reducing the overconsumption of inexpensive and convenient foods.

  • Objectives The purpose of this study is to confirm the effect of alleviating inflammation through creating skin fat barrier from Scutellaria baicalensis extract. Methods Four-week-old Balb/C mice were divided into four groups: control group (Ctrl), lipid barrier eliminated group (LBEG), dexamethasone (DM) treated group after lipid barrier elimination (DMTG), and Scutellaria baicalensis (SB) treated group after lipid barrier elimination (SBTG). Scutellaria baicalensis extract were administered for 5 days after removal of the fat barrier. Changes in skin condition, improvement of the fat barrier, and relief of inflammation were observed in each group. Results Compared to LBEG and DMTG, pathological skin damage and tissue changes were less in SBTG, and transepidermal water loss (TEWL) and pH were also significantly reduced. Filaggrin was also significantly increased in SBTG. KLK7, PAR-2, and TSLP in SBTG also showed significant reduction compared to the LBEG and DMTG. Conclusions Scutellaria baicalensis extract restores skin barrier and relieves inflammation through the creation of skin fat barrier. This means that the Scutellaria baicalensis extract can regulate Th2 differentiation through the creation of the epithelial fat barrier.

  • This study investigated the anti-obesity effects of Coriandrum sativum L. ethanol extracts in a high fat diet-induced obesity model (DIO). We confirmed the anti-obesity effects by analysing the expression of the related proteins, weight gain, dietary intake, dietary efficiency, blood biochemistry, histological analysis and western blot analysis. After oral administration of Coriandrum sativumL. ethanol extracts at concentrations of 250 and 500 mg/kg, a significant improvement in dietary efficiency, reduction in weight gain, triglycerides, total cholesterol and LDL-cholesterol in blood lipid was observed for 8 weeks. In addition, improvement in blood glucose and metabolism confirmed through glucose tolerance test was observed. Further, the concentration of alanine transaminase (ALT) in blood was significantly decreased, which improved the fatty liver caused by high-fat diet intake as confirmed by liver tissue analysis. This phenomenon was confirmed to decrease the expression of fat accumulation-related PPARγ and FAS protein in the liver tissue. Especially, it is believed that FAS, a liposynthetic enzyme, has a stronger inhibitory effect than PPARγ. Therefore, Coriandrum sativum L. ethanol extract is thought to improve obesity by reducing blood lipids levels, improving glucose metabolism and inhibiting synthesis of the fat that accumulates in the liver in high-fat diet-induced obesity animal models.
