A preliminary diet experiment utilizing Jerusalem artichoke's inulin, lotus leaf powder, nettle powder and eucalyptus powder extract indicated that combining all four elements gave the most effective result. Therefore, a study was conducted to evaluate the effectiveness of combined diet for weight loss. In this study, Sprague-Dawley, male white rats about 200 g in weight was fed with high fat diet for 8 weeks in order to induce obesity followed by 4 week administration of combined diet to look into the effect of the diet. After a total of 12 weeks of feeding, factors relevant to weight, blood, and lipid metabolism by liver in the body were researched and histologic change was examined with optical microscope. In terms of weight change, both high fat diet group and regular diet group gained weight from high fat diet for 8 weeks compared to normal group. Then, for another 4 weeks, while normal group and high fat diet group kept gaining weight, combined diet group which was provided with high fat diet for 8 weeks, lost weight to the normal group level after 3 week administration of diet. However, after the 4th week of administration, the group weighted significantly less than the normal group and the efficiency of diet also significantly dropped. In the biochemical analysis of blood, total cholesterol, LDL-cholesterol, triglyceride, glucose, GOT, GPT, ${\gamma}-GTP$ and creatine showed significant increase in high fat diet group and there was no significant difference between diet group and normal group except for GPT, ${\gamma}-GTP$ and creatine. In the biochemical analysis of liver, there was significant increase in LDL-cholesterol, triglyceride of high fat diet group compared to normal group, while there was no significant difference in term of total cholesterol and HDL-cholesterol. Compared to normal group, diet group had higher HDL-cholesterol, while total cholesterol dropped significantly. There was no significant difference in terms of LDL-cholesterol and triglyceride. Besides, in high fat diet group, observation of histologic change in liver and change in ultrastructure showed volume increase of hepatic cell and severe fatty degeneration in hepatic cell around hepatic vein. However in diet group, like normal group, no pathological change was observed in terms of cytoplasm, nucleus and capillary in hepatocyte and the alignment of hepatocyte had regularity thanks to the administration of combined diet. Therefore, combined diet utilizing Jerusalem artichoke's inulin, lotus leaf powder, nettle powder and eucalyptus powder was proven to be an effective measure to prevent and improve obesity as a result of abnormal adipose deposition.

Authors obtained the results of the investigation for healthy people through the routine health examination of public officers and school personnels in private schools which were conducted in 1986. The results were as follows; 1) Those who were above 20% incidence of body weight for 3917 study population were revealed 5.2% in males and 15.1% in females of $45{\sim}49$ years of age, 6.8% in males and 24,4% in females of $50{\sim}54$ years old, 5.8% in males and 13.5% in females of $55{\sim}59$ years old, and they showed that the incidences were significantly higher in females than in males at 0.01, 0.01 & 0.05 in P-values respectively. 2) Mean$\pm$SD of total cholesterol level for 3,265 healthy people with both sexes combined showed $181.63{\pm}34.67$ and it was $188.61{\pm}33.96$ in people of $40{\sim}59$ years old with both sexes combined. Mean$\pm$SD of fasting blood sugar level for 3,266 healthy people showed $87.28{\pm}11.67$ and that in $40{\sim}59$ years of age were $89.14{\pm}11.74$. Therefore, mean$\pm$2SD of total cholesterol and fasting blood sugar were $112.26{\sim}250.98mg/dl$ in males and $58.93{\sim}110.61mg/dl$ in females. 3) This investigation showed 3.0% in above 251 mg/dl of total cholesterol and 3.5% in above 111 mg/dl of fasting blood glucose. 4) Those who were above 251 mg/dl of total cholesterol and above 111 mg/dl of blood glucose in above 20% incidence of body weight according to the Broca' index were 12.9% and 7.6% respectively. 5) Those who have hypertension according to the criteria of WHO with obesity of above 20% incidence of body weight showed 8.4% in both sexes (8.2% in males and 8.7% in females). 6) Blood pressures increased according to more aging and gaining body weight.

This study was carried out to investigate the effect of Yacon (Polymnia sonchifolia Poepp. & Endl.) powder on cholesterol-lowering and anti-obesity effects in rats fed a high fat-high cholesterol diet for 4 weeks to induce hyperlipidemic and obese rat model. Weight-matched male Sprague-Dawley rats were assigned to four groups according to dietary fat, cholesterol levels and Yacon powder levels. Experimental groups were normal diet group (N), high fat-high cholesterol diet group (HFC), high fat-high cholesterol diet with 5% Yacon powder group (HFC-PSL) and high fat-high cholesterol diet with 10% Yacon powder group (HFC-PSH). The body weight gain and FER were increased by a high fat-high cholesterol diet, but gradually decreased in the Yacon powder fed groups compared with the HFC group. Food intake was lower in HFC groups compared with N group. The liver and adipose tissue weights of HFC group were heavier than those of N group, whereas those of groups administered Yacon powder were gradually decreased. The serum ALT, AST, ALP and LDH activities elevated by a high fat-high cholesterol diet were significantly decreased by Yacon powder administration. Levels of serum total cholesterol, LDL-cholesterol, atherogenic index and cardiac risk factor showed a decreasing tendency in the Yacon powder fed groups compared with HFC group. The serum HDL-cholesterol level decreased in the HFC group and markedly increased in the Yacon powder fed groups. Levels of total cholesterol and triglyceride in liver and adipose tissues were lower in Yacon powder administered groups than those in HFC group. These results suggest that Yacon powder may improve lipid metabolism of serum, liver, and adipose tissue and potentially reduce lipid storage.

This study investigated the effects of Stevia rebaudian bertoni leaf extract on lipid profiles in C57BL/6J mice, as compared to stevioside. Fourty mice were divided into four groups: NC (normal diet and DW), HC (high fat diet and DW), HLSV (high fat diet and stevia leaf extract, 1 mL/kg/day), and HSS (high fat diet and stevioside, 1 mL/kg/day). Serum triglyceride concentrations were significantly lower in the HLSV and HSS groups than in the HC group. Epididymal fat pad weights were significantly lower in the HLSV and HSS groups than in the HC group. We also evaluated the serum and liver carnitine levels (NEC, AIAC, ASAC, TCNE) of all the groups. These results were supported by the mRNA expression of enzymes related to lipid metabolism (ACC, PPAR${\alpha}$, ACS, CPT-I) assessed by RT-PCR. Overall, the results show the antiobesity effects of stevia leaf extract as compared to stevioside in high fat diet induced obese mice.

This study investigated the anti-hyperlipidemic and anti-obesity effects of Sparassis latifolia (S. latifolia) fruiting body powder in rats fed with a high fat and cholesterol diet (HFD). Rats were fed a normal control diet (ND), an HFD, an HFD supplemented with 5% fruiting body powder of S. latifolia (HFD+SL), or an HFD supplemented with 0.03% simvastatin (HFD+SS), for 6 weeks. The HFD group demonstrated considerable increase in body weight gain, the food efficiency ratio (FER), and plasma cholesterol and triglyceride levels, compared to the ND group. In contrast, the HFD+SL and HFD+SS groups showed significantly reduced body weight gain, food intake, and plasma cholesterol and triglyceride levels compared to the HFD group. In particular, the HFD+SL and HFD+SS diets significantly suppressed the occurrence of non-alcoholic fat deposits in the liver. Taken together, these results suggest that dietary supplementation of the fruiting body powder of S. latifolia in an HFD could lower the risks of hyperlipidemia, atherogenesis, and obesity and may be used as a functional food to manage cardiovascular disease and fecal lipid and cholesterol levels.

Purpose: Lymphedema is edema developing mainly in the arms and legs due to an abnormal lymphatic system, over one hundred millions of patient worldwide suffer from it. At present, prevention is the best treatment. Thus, It is important to know which patient are more pone to develop it in order to prevent it. By evaluating the risk factor for lymphedema, we intended to find the effective prevention. Methods: We have investigated that outpatients who chiefly complained of lymphedema visited the lymphedema clinic at one university hospital from September 1 in 2003 to August 31 in 2005. We evaluated the risk factor for lymphedema by questionnaires. Questionnaire consists of demographic data, disease factor, treatment factor, posttreatment factor. We evaluated the correlation between lymphedema with each factor. Results: The total number of patients was 50, 19 patients with breast cancer and 31 patients with cervical cancer. In terms of stages of edema, 12 patients were below stage 1 and 38 patients were above stage 2. The incidence of lymphangitis was more frequent, more obese and the impairment of the site of edema site more severe, the stage of cancer was higher in the patients higher than stage 2 than in the patients below stage 1 (P>0.05). Conclusion: Lymphedema is more severe when the cancer stage in higher, accompanying more frequent infections, more obesity and more impairment at the site of edema site. Above all, cancer stage and the impairment of edema site are impossible to correct but obesity and infection may be corrected. Therefore we speculate that we are able to protect the aggravation of edema by weight reduction and infection control.

Objectives: Hypertension is the most important risk factors for the cerebrovascular diseases, and also for coronary heart diseases, it is therefore very important that the people have a knowledge on nature of hypertension and it's high risk in order to prevent and detect the hypertension as early as possible. Methods: This study was done to find out the knowledge on hypertension of 434 parents of elementary school students from Kimjae city, Jonbuk province, they were parents in grade 4, 5 and 6 attending two elementary schools. The survey took 10 days from November 20 to November 30, 2003. Results: first, The highest correct answer(94.5%) was "obesity is risk factors for hypertension", followed by "hypertension is closely related with hereditary factors(91.0%) and "high sodium intake is associated with high blood pressure"(85.7%). The lowest correct answer(77.4%) was the classification of blood pressure level between normal and high. Second, Rate of blood pressure measurement for fathers was 53.7% and 54.8% in mothers. Awareness of own blood pressure by fathers was 84.1 %, while 91.1% by mothers. Third, According to blood pressure level reported by parents, fathers with normal blood pressure was 59.2%, high normal blood pressure was 12.2%, while hypertension was 28.6%. It revealed that prevalence of hypertension of fathers was higher than mother (normal: 74.5%, high normal: 7.7%, hypertension: 18.2%). Conclusions: From the results of this study, it is important to strengthen the health education about hypertension for community people and also school students.

Background: It is important to provide health education to students to ensure a healthy life. Using the internet for health education may be a way to overcome the practical barriers to health education such as time and content. This study was conducted to investigate the demands for health education using the internet. Subjects and methods: Six hundreds and twenty-four and male female students in middle and high schools, who lived on Gyeongju-si and Seongju-gun in Gyeongsangbuk-do province, were interviewed by means of structured questionnaires, from March 5 to March 28, 2003. Results: More than 90% of the subjects had their own computers, and nearly 38% of those possessing their own computers had accessed internet sites related to health and medicine. Middle school students and in particular, female students were more desirous for health education through e-mail. Regarding content, the three major topics which the respondents wanted to learn about were healthy lifestyles, growth and development, and disease prevention. In terms of the interval for providing educational materials, over half of the students wanted information once a week. Most of the students wanted to have the quantity of the material be one page. In addition, there were numerous additional topics requested by the students such as sleep and health, contraception and family planning, safety education, cancer prevention, emotional instability of juveniles, the utilization of medical care facilities, stress management, etc. Conclusion: The students had a desire for health education through the use of e-mail, and methods and materials should be developed for appropriate health education using the internet.

The effects of dietary fiber isolated from Synurus deltoides on constipation induced by loperamide (4 mg/kg/day) were investigated. Food intake and body weight both decreased in the 5% S. deltoides dietary fiber and loperamide-treated group (SD5) and 10% S. deltoides dietary fiber and loperamide-treated group (SD10), whereas fecal water contents increased by 2.4 and 3.4-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of S. deltoides. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also significantly lower than those in the control group. These results suggest that dietary fiber isolated from S. deltoides might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.

We investigated ${\alpha}$-amylase, ${\alpha}$-glucosidase and lipase inhibitory activity of extracts collected from wild plants in Gangwon-do. 90 wild plants were collected and their water and ethanol extracts were obtained. Results of measuring ${\alpha}$-amylase inhibitory activity indicated more than 80% of activity inhibition in 10 mg/mL concentration for ethanol extracts of three plants and water extracts of two plants. For ${\alpha}$-glucosidase inhibitory activity, ethanol extracts of thirteen plants and water extracts of three plants showed more than 80% of activity inhibition in 10 mg/mL concentration. In the experiment of inhibiting lipase activity, ethanol extracts of seven plants and water extracts of one plants showed above 80% of activity inhibition in 10 mg/mL concentration. These results suggest that the selected extracts could be potentially used as a resource of bioactive materials for health functional foods.
