The study was designed to observe the effect of complete listing for 10 days on body fatness, serum leptin level and lipid profile in thirty women who were admitted to fasting Clinical Program in Kyung-Hee Oriental Medical Center. Most of the subjects had food habits of over-eating and preferred oily foods which was correlated to the increase of body weight and BMI during realimentation. Average loss of body weight was 7.98kg and waist-hip ratio was significantly decreased during fasting. Body weight showed significant positive correlation with body fat(r=0.8182), lean body mass(r=0.7797) and total body water(r=0.7563). Body fat was gradually reduced after 9 days fasting, but lean body mass was not diminished any more after 7 days luring. Serum leptin level was significantly decreased after luring and re-feeding. The leptin showed significant positive correlation with body weight(r=0.9324), body mass index(r=0.8279) and body fat(r=0.8376). The levels of serum total cholesterol and LDL-C were significantly increased but HDL-C level was significantly decreased after fasting which increased could be harmful for persons with hypercholesterolemia. VLDL-C and triglyceride levels were not significantly decreased after fasting. Serum total free fatty acid level was significantly increased after fasting. These data suggest that the best way of maintaining the reduced body weight was to carry out the modification of food habits and behavior in daily lift. It could not be recommended to repeat often complete luting for reduction of body weight. (Korean J Nutrition 33(1) : 42-48, 2000)

Objectives: We conducted a retrospective chart review to investigate the effects of Korean Medicine (KM) treatment on weight loss in patients with morbid obesity (body mass index [BMI]≥30 kg/m²) and to compare the effects of KM counseling and non-counseling on weight loss. Methods: We performed a retrospective chart review of patients with morbid obesity who received KM treatment for at least 1 month. We evaluated the effects of KM treatment on body weight, BMI, body fat, fat mass, EuroQol-5D, and the Korean version of the obesity-related quality of life scale (KOQOL). We also assessed the liver and kidney functions, and adverse events. We performed a comparative analysis between the counseling and non-counseling groups. Results: A total of 37 patients who underwent 4 weeks of KM treatment involving Wolbi-tang, electroacupuncture, and KM counseling were included in this study. Twenty-one patients were assigned to the counseling group and sixteen patients to the non-counseling group. There was a significant decrease in weight, BMI, fat mass, and KOQOL (P<0.05) with improvements in total cholesterol, low-density lipoprotein, and triglycerides. The counseling group had a greater reduction in body weight, BMI, body fat, and fat mass compared to the non-counseling group, although it was not significant. In the BMI below 35 (n=25), the reduction ratio of body weight, body fat mass, and body fat was higher in the counseling group than in the non-counseling group; additionally, body fat decreased significantly in counseling group (P<0.05). No severe adverse effects were observed. Conclusion: KM treatment could be effective for weight loss, especially in patients with morbid obesity, KM counseling could also be a good tool for weight loss, typically in patients with BMI<35 kg/m².

A mutation in the promoter region of uncoupling protein 3 (UCF3), specifically the -55C longrightarrow T transition, may influence an individual's energy metabolism and body weight. The objective of this study was to investigate the effect of a weight reduction program on endocrine functions and body fat distribution, related to UCP3 promoter genotype. Ninety overweight pre-menopausal female subjects participated in the weight reduction program at Yonsei University Hospital, and were placed on a calorie-restricted diet (300 kcal less than their daily requirements) for 12 weeks. After 12 weeks, all subjects on the program lost approximately 5% of their initial body weights and had lower Body Mass Index (BMI) values. Among the 90 women, 56 had a normal (without mutation) UCP3 genotype, while 34 women had mutations in the promoter region of UCP3. Despite similar weight reductions in both groups, a significantly higher decrease in abdominal adipose tissue was observed in the normal UCP3 genotype group, compared to the group with mutations. In particular, there was a significant reduction of fat at the lumbar 1 (Ll) level in the without-mutation group. Serum levels of total cholesterol, apolipoprotein Al were significantly decreased in the without-mutation group, by 4.4% and 5.7% respectively. Serum levels of hormones were not significantly changed in both groups artier the intervention. However, in the group without the mutations, the leptin level significantly reduced by 23.4% (p<0.001). Serum free fatty acid (FFA) concentration was significantly increased in the group with mutation following the weight reduction program. On the other hand, FFA responses were shown similar increases in both groups. In conclusion, although no difference was found in the magnitude of weight reduction in both groups, there were significant differences in body fat distribution and in endocrine function between the groups.

Recently high voltage impulse (HVI) technique has been extensively studied for desalting processes to control the $CaCO_3$ scale formation in industrial water practices such as power plant, boiler, and heat exchange operations. Investigation of the operational parameters for the HVI is important, however, those had not been reported yet. In this study, the effect of initial feed volume and contact time on reduction of calcium ion concentration by the HVI technique was investigated. Initial feed volumes of artificial hard water which contained 100 mg/L of $Ca^{2+}$, were set to 1, 2, and 3 L respectively. After 24hr of HVI contact with 12kV, $Ca^{2+}$ ion was reduced to 50, 29 and 19 % of their initial concentration, indicating that calcium removal increased as initial feed volume decreased. This implies the applied HVI pulse energy per unit mass of calcium is important parameter determining overall desalting efficiency. A series of extended operations of HVI up to 30 days verified the long term stability of the HVI system. The calcium ion declined to 40 mg/L after 2~3 days, and further reduction of calcium was not achieved, indicating that optimum operation time could be 2~3 days under these experimental conditions. Consequently, it was confirmed that the important operational parameter of HVI technique is initial feed volume and contact time as well as the applied voltage that was already proven in the previous study.

Back ground : Subcutaneous fat area is the main factor involved in replacement disease and arteriosclerosis. Simple weight control is the appropriate medical treatment. It's understood that weight reduction does not only reduce the fat concentrations in blood but also reduces blood pressure, improves glucose levels in diabetes patients and reduces incidents of heart disease. there are several methods for reducing fat in the abdominal region but their effectiveness is not folly understood. one method is electrical stimulation of the problem areas. Method : From May 1st 2002 to October 31st. The 15 subjects who received medical examination were aged between 25 and 53 and were of mixed gender. The subjects were divided into two groups one to received functional electrical stimulation and the other a control group. Using Broca's criterion for judging fat grades. I analysed the differences between the two groups before and after the treatment. Subjects received functional electrical stimulation on the abdominal muscle intensity 50Hz. They received this treatment 4 days a week for 40 minutes a day. In the case of aerobic exercise, at the Treadmill, we used it with the intensity of $75\%$ maximum heart rate (220-age). Result 1)After functional electrical stimulation in the case of male subjects, the weight was reduced 1.93kg, obesity $2.60\%$, fat mass 2.73kg, Percent body fat $4.40\%$, waist circumference 6.53cm, circumference of hips 5.53cm. On the other side, the quality of muscle was increased at the rate of 1.03kg, but it's not attentional level. The subcutaneous fat area was reduced by $26.63cm^2$, the visceral fat area was reduced by $43.00cm^2$, In the female subjects, we can see the reduction of fat grade by $26.63cm^2$, the quantity of body fat by 1.5kg, percent body fat by $1.77\%$, circumference of waist by 4.02cm, circumference of hips by 3.67cm, weight by 1.40kg but was increased 0.72kg at the quantity of muscles. We can see the reduction also in the subcutaneous fat area $24.03cm^2$, the visceral fat area by $25.36cm^2$. 2)After aerobic exercise, on the male subjects, we can see reduction of weight by 3.36kg, obesity by $4.00\%$, fat mass by 2.83kg and we can see increase at the soft lean mass by 2.96kg, but we can see reduction, the percent body fat by $3.03\%$, fat distribution by $0.023\%$, circumference of waist by 3.10cm, circumference of hips by 2.23cm. The female subjects show a reduction in the weight by 2.48kg, percent body fat by $2.20\%$, show an increase in the soft lean mass by 1.54kg. We can see a reduction in the quantity of fat mass by 2.32kg, the percent body fat by $2.80\%$, the circumference of waist by 2.16cm, the circumference of hips by 2.68cm, the fat distribution by $0.016\%$, the subcutaneous fat area by $15.25cm^2$ the visceral fat area by $11.52cm^2$. After aerobic exercise, we can't see the attentional change at the total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol. 3)After the application of functional electrical stimulation and aerobic exercise, in result of measurement on the body ingredient, we could see the weight reduction and increase the quantity of muscle with the male group who exercised aerobic. We can see the attentional rate on the electrical stimulation about abdominal fat rate, circumference of waist, circumference of hips. The other hand, I couldn't see the attentional differences between the two groups in the rate of fatness and quantity of body fat and the rate of body fat. There isn't any attentional difference in the area of fat under skin, on the contrary, There is attentional difference in the fat in the internal organs area at the electrical stimulation site. We can't see the attentional change of total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol between electrical stimulation and aerobic exercise. 4)After execution of functional electrical stimulation and aerobic exercise, in result of measurement on change of body ingredient among female objects, We could see weight reduction, increase at muscle quantity in the aerobic exercise group. We could see the attentional differences in the rate of fatness, the rate of abdominal region, the circumference which received electrical stimulation. But, we couldn't see the attentional differences between two groups in the quantity of body fatness, the circumference of hips. The subcutaneous fat area doesn't show the attentional differences. On the Contrary, we could see lots of differences in the visceral fat area of the electrical stimulation group. Conclusion The results show that functional electrical stimulation and aerobic exercise have insignificant differences when if comes to total cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol. Though there is affirmative change in body ingredient after both electrical stimulation and aerobic exercise. Functional electrical stimulation is more effective on the subcutaneous fat area and in changing visceral fat area. There fore. It is concluded that the physical therapy is more effective in the treatment of abdominal fatness.

In previous studies, we performed joint animal studies and clinical trials between Yonsei University and Oryza Oil & Fat Chemical Co. Ltd. We have shown that coffee bean extract has potent anti-obesity and hypotriglyceridemic activities as well as beneficial effects on body fat reduction.In this study, the effects of coffee bean extract (100 mg/capsule) on body fat reduction were evaluated in overweight/obese women (body mass index of 25~30 $kg/m^2$ or body fat > 30%) not diagnosed with any type of disease. Subjects were randomly assigned to a coffee bean extract group (n=10) or placebo group (n=10). We measured anthropometric parameters, abdominal fat distribution by computed tomography and blood components before and after the 8week intervention period. After supplementation, the coffee bean extract group showed body weight (p=0.08), body mass index (p=0.06), hip circumference (p<0.05), and upper waist circumference (p< 0.01). In addition, after 8 weeks, the coffee bean extract group showed a significant decrease in abdominal internal fat area compared to 0 weeks (0 weeks : $155.8cm^2$; 8 weeks : $145.9cm^2$, ${\Delta}$ change : $-9.9cm^2$, respectively). However, there were no significant differences in lipid profiles or serological measurements between the coffee bean extract group and placebo group. The results of our human study demonstrated that coffee bean extract supplementation for 8 weeks has beneficial effects on reducing abdominal internal fat area as well as hip and waist circumferences.

생선 등에서 비린내 성분중 하나인 트리메틸아민을 이취 유발 물질로 하여 6% 쌀뜨물을 기준으로 아밀로오스, 전분, ${\alpha}$-cyclodextrin 등과 이취 제거효과를 전자코를 이용하여 비교 분석해보았다. 쌀뜨물과 이취물질의 반응시간이 길수록 그만큼 결합이 많이 이루어져 이취 저감화 효과가 크게 나타났으며 쌀뜨물의 농도가 높을수록 반응할 수 있는 전분의 양이 많아 그만큼 이취가 적게 나타나는 것을 알 수 있었다. 또한 쌀뜨물이 아닌 다른 탄수화물 용액과의 반응에서 6% 쌀뜨물과 전분의 효과는 비슷하였으며 ${\alpha}$-cyclodextrin은 농도가 10배 정도 낮음에도 불구하고 비슷한 경향을 보여 그만큼 이취 저감화 효과가 큰 것을 알 수 있었다. 반면 밀가루는 단백질의 함량이 높아 다른 물질들에 비해 결합정도가 낮을 거라 예상되며 쌀뜨물의 이취 저감화 효과는 아밀로오스뿐 아니라 아밀로펙틴의 영향도 받는 다는 것을 간접적으로 예상되는 바이다. 이러한 결과들을 통해 향후 신제품 개발이나 품질 관리에 활용될 수 있을 것이며 이러한 이취 제거 성분들은 전통식품 같이 첨가물이나 가공품을 많이 첨가하기가 어려운 시료에서의 활용이 높을 것으로 기대되는 바이다.
