Objectives : This research was performed to investigate the effect of invasive low level laser acupuncture therapy(LLLAT) at Yolgyol+yogu(LU7+LR5) on weight gain, food intake, food efficiency, lipid metabolism and liver function in hyperlipemia rats. Methods : Experimental groups were divided into high fat diet cup(Control group), high fat diet and 15 mW/5 min LLLAT at LU7+LR5(15 mW/5 min group), 15 mW/10 min LLLAT at LU7+LR5(15 mW/10 min group), 30 mW/5 min LLLAT at LU7+LRS(30 mW/5 min group), 30 mW/10 min LLLAT at LU7+LR5(30 mW/10 min group). LLLAT was treated at the 15,30mW-5,10min once a 2day during 5 weeks. Results : Body weight was decreased significantly in 30 mW/s min group and 30 mW/10 min group compared with control group. Food intake was decreased significantly in 15 mW/5 min group and 15 mW/10 min group compared with control group. Food efficiency was decreased significantly in 30 mW/10 min group compared with control group. In the lipid metabolism, total cholesterol, HDL-cholesterol and free fatty acid were increased significantly in 15 mW/5 min group and 30 mW/10 min group compared with control group. LDL-cholesterol was increased in 30 mW/10 min group and phospholipids was decreased significantly in all experimental group compared with control group. triglyceride was not showed significant result in all experimental group. In the liver function, AST was not showed significant result in all experimental group, ALT and ALP were increased significantly in 30 mW/10 min group, ALP was decreased in 30 mW/5 min group compared with control group. Conclusions : LLLAT at LU7 and LR5 can manage hyperlipemia by controlling body weight, food intake, food efficiency ratio and lipid metabolism.

We previously reported that cholesteryl ester transfer protein (CETP) inhibitory peptides (designated $P_{28}$ and $P_{10})$ have anti-atherogenic effects in hypercholesterolemic rabbits (Biochim. Biophys. Acta (1998) 1391, 133-144). To further investigate those effects, we studied rabbit plasma that was collected after 30 h of a $P_{28}$ or $P_{10}$ injection. We found that there is a strong correlation between the in vivo CETP inhibition effects and alterations of lipoprotein particle size distribution in rabbit plasma, as determined on an agarose gel electrophoresis and gel filtration column chromatography. In vivo effects of the peptide were observed again in C57BL/6 mice that expressed simian CETP. The $P_{28}$ or $P_{10}$ peptide ($7\;{\mu}g/g$ of body weight) that was dissolved in saline was injected subcutaneously into the mice. The $P_{28}$ injection caused the partial inhibition of plasma CETP activity up to 50%, decreasing the total plasma cholesterol concentration by 30%, and increasing the ratio of HD/total-cholesterol concentration by 150% in the CETP-transgenic (tg) mice. The CETP inhibition by the $P_{28}$ or $P_{10}$ made alterations that modulated the size re-distribution of the lipoproteins in the blood stream. Particle size of the very low (VLDL) and low density lipoproteins (LDL) from the peptide-injected group was highly decreased compared to the saline-injected group (determined on the gel filtration column chromatography). In contrast, The HDL particle size of the $P_{28}$-injected group increased compared to the control group (saline-injected). The expression level of the CETP mRNA of the $P_{28}$-injected CETP-tg mouse appeared lower than the saline-injected CETP-tg mouse. These results suggest that the injection of the CETP inhibitory peptide could affect the CETP expression level in the liver by influencing lipoprotein metabolism.

Purpose : Chronic renal failure is often accompanied by severe dyslipidemia, a known risk factor for cardiovascular disease. Lipoprotein(a) [Lp(a)] has recently been characterized as a risk factor for atherosclerosis and thrombosis. Cardiovascular disease is the leading cause of death in adult patients on dialysis. However, there are only limited data available concerning risk factors for atherosclerosis in uremic children. We have measured serum levels of lipids, lipoproteins, apolipoproteins and Lp(a) in uremic children with maintenance dialysis. Methods : Ten uremic children with hemodialysis (HD) and 14 with peritoneal dialysis (PD) in our dialysis unit were included in this study. The mean age of HD patients was $162{\pm}59$ months and the male to female ratio was 7:3. The mean age and sex ratio of PD patients were $123{\pm}63$ months and 6:8, respectively. The levels of cholesterol, triglyceride, lipoproteins, apolipoproteins and Lp(a) were measured from serum sampled after 14 hours of fasting. The normal control levels were cited from 2 articles presenting the normal blood lipid and lipoprotein levels of primary school and middle school children in Korea. Results : There was no difference in age, sex ratio, body mass index and duration of dialysis between the HD and the PD group. The serum concentration of the cholesterol, triglyceride and apolipoprotein B were significantly elevated in dialysis patients compared with normal subjects. The serum level of Lp(a) was significantly elevated in only PD group. The serum Lp(a) level was below 30 mg/dl in 13 and above 30 mg/dl in 11 patients. The serum albumin level was significantly decreased in high Lp(a) group than in low Lp(a) group. Conclusion : The uremic children receiving dialysis reveal abnormal serum lipid and lipoprotein profiles. These results suggest that they have a higher risk for coronary heart disease, although there has been no clinical evidence of coronary heart disease at present. A long-term follow-up study of these children to clarify the suggestion should be started now.

This study was designed to investigate the effect of garlic shoot extract administration on serum and liver tissue lipid levels in hyperlipidemic rats. The rats were fed a 45% high-fat diet to induce hyperlipidemia. They were then administered garlic shoot extract (50%) and ethanol extract (75%) at 200 mg/kg B.W./day (GSA-1, GSB-1) and 400 mg/kg B.W./day (GSA-2, GSB-2) for 5 weeks. The total lipid and triglyceride contents in serum were lowest in the GSB-2 group, and the total cholesterol content was significantly lower in the GSA-2 and GSB-2 groups than in the control group. The high density lipoprotein (HDL)-cholesterol content of the GSB-2 group was similar to that of the normal group. The low density lipoprotein (LDL) and very low density lipoprotein (VLDL)-cholesterol contents were significantly lower in the GSB-1 and GSB-2 group than in the control group. atherogenic index (AI) and cardiac risk factor (CRF) were lowest in the GSB-2 group (0.58 and 1.57, respectively). Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) activities were significantly higher in the control group than in the normal group, and the levels of AST, ALT, and ALP were significantly lower in the GSA-2 and GSB-2 groups than in the control group. The total lipid content in liver tissue was significantly lower in all the experimental groups compared to that of the control group, but it was not significantly different among the experimental groups. The total cholesterol and triglyceride content in liver tissue was lowest in the GSB-2 group. Antioxidant activity in serum and liver tissue was highest in the GSB-2 group (40.16% and 47.41%, respectively).The thiobarbituric acid reactive substance (TBARS) content in serum and liver tissue was lowest in the GSB-2 group, with the significant difference. Our results suggest that garlic shoot extracts may improve lipid metabolism in serum and liver tissue and potentially reduce hyperlipidemia.

The purpose of this study was to investigate the effect of Sea Tangle supplementation and exercise training on blood glucose and lipid profile in rats. Twenty seven, 4-week old male Sprague-Dawley rats were divided into the control group (C, n=9), sea tangle group (D, n=9) and sea tangle+exercise group (D+T, n=9). Exercise training was performed 5 days a week using a treadmill running program for 6 weeks (5 m/min, 0% grade, 30 min). There was no difference in blood glucose (C: $175.9{\pm}47.5$, D: $173.9{\pm}34.0$, D+T: $165.0{\pm}38.0\;mg/dl$) and triglyceride (C: $251.1{\pm}91.8$, D: $215.0{\pm}90.0$, D+T: $200.0{\pm}89.3\;mg/dl$) among the groups. Total cholesterol value of the D+T group ($81.8{\pm}11.2\;mg/dl$) was significantly lower than that of the C ($103.0{\pm}13.5\;mg/dl$) and D ($102.1{\pm}14.5\;mg/dl$) groups. High density lipoprotein cholesterol (HDL-C) was significantly high in the D+T ($40.9{\pm}9.7\;mg/dl$) group compared with the C ($32.6{\pm}3.8\;mg/dl$) group and D ($31.7{\pm}7.3\;mg/dl$) group. The value of low density lipoprotein cholesterol (LDL-C) for the D ($98.0{\pm}41.0\;mg/dl$) group was statistically lower than the C($114.5{\pm}41.8\;mg/dl$) group, and higher than the D+T ($91.2{\pm}41.7\;mg/dl$) group. In conclusion, sea tangle injection and exercise had a positive effect on blood lipid profiles.

Purposes: The purposes of this study are to investigate the definition, components, prevalence, and associated factors of metabolic syndrome and suggest the management strategies for workers. Method: This study was conducted by literature review. Results: Metabolic syndrome by the NCEP-ATP III is the clustering of three or more of five conditions: abdominal obesity, high triglycerides, low levels of HDL cholesterol, high blood pressure, and high glucose(blood sugar). The prevalence of the metabolic syndrome by modified NCEP-ATP III in South Korean workers was about 20 to 25%. Metabolic syndrome is caused by many associated factors, namely, age, family history, socioeconomic status, job strain, shift work, psychosocial distress, bad health behaviprs and so on. Conclusions: To prevent metabolic syndrome at worksites, multifactorial risk factor assessments and preventive approaches are required. Socioeconomic factors such as education, working status should be nationally importantly considered for the health inequality of workers. Occupational health nurse, at first, can start weight control, smoking cessation program. stress management, the improvement of work environment. Next stage, early diagnosis and treatment for metabolic risk group can be performed.

Objectives: The aim of this study was to evaluate the effects of a lifestyle modification program for Korean adults with cardiovascular disease risk factors on their health behaviors and health status. Methods: A total of 448 adults with abdominal obesity and additional cardiovascular disease risk factors(high blood pressure, low HDL-cholesterol, high triglyceride or high blood glucose) were randomly assigned to either an intensive intervention group (IIG, n=216) or a minimal intervention group(MIG, n=232). Participants in the IIG received lifestyle modification program which consisted of health counseling with nutrition assessment, health booklet and health diary, while those in MIG received minimal information. Results: The participants in the IIG significantly improved dietary habits(p<.05), retrained eating(p<.001), external eating(p<.01) behaviors, leisure time physical activity(p<.05), dietary self-efficacy(p<.01), exercise self-efficacy(p<.01) and MetS score(p<.001) after 3 months. In addition, the participants in the IIG showed more improvement in dietary habits(p<.05) compared with those in the MIG. Conclusion: The lifestyle modification program was effective in improving some health behaviors, behavioral determinants and cardiovascular risk factors for a short term.

Purpose: This study was to compare changes in health behaviors, motivational factors, cardiovascular risk factors, and functional status (SIP) after implementing the 6-month motivation-enhancing program to institutionalized elderly women. Methods: Sixty-four elderly women participated. Face to face interviews with blood sampling and anthropometric assessment were conducted at the pretest, 10 weeks and 6 months during the program. Results: 1. The program participants showed significantly better health behaviors over 6 months. The mean motivational level was also significantly improved, especially for perceived benefits, perceived barriers, and emotional salience. 2. The mean of cardiovascular risk factors for the participants was 21.8 at the level of low to moderate risk. After completing the program, total risk score was significantly decreased to 18.7 at 10 weeks, and further to 17.7 at 6 months. A significant reduction was also found in HDL and LDL-cholesterol levels, blood pressure, obesity, inactivity, and stress. 3. The functional status (SIP) was 11% at the baseline and significantly changed in positive direction at 10 weeks(M=9.3) and at 6 month(M=6.3). The significant improvement was also found in physical and psychosocial dimensions and sleep/rest dimension. Conclusion: The motivation enhancing program was effective to reduce cardiovascular risks and to improve the functional status of institutionalized elderly women by motivating them to perform better health behaviors.

The effects of pine needle extracts on serum and liver lipid contents were evaluated in rats. Thirty male Sprague-Dawley rats weighing 329$\pm$4 were divided into five groups and fed high fat diets for four weeks. Each group was administered with following pine needle extract: control, water ; WE-3, hot water extract(3% PN) ; WE-6, hot water extract(6% PN) ; AE-3, acetone extract(3% PN) ; AE-6, acetone extract(6% PN). Weight gains were significantly lower in WE-6 group than other groups. But there was no significant difference among other three groups. Intakes of diet and water containing the extract and the weights of liver, kidney, heart and spleen were not significantly different among the groups. The contents of serum and liver triglyceride in the WE-3 group were lower than those of control group. The contents of HDL-cholesterol in serum of the WE-3 group was significantly higher than other groups. The value of risk factor index(RFI) was determined to be low especially in case of WE-3 group. Due to pine needle extract administration, concentration of liver total lipid in WE-3 group was significantly lower than that of the control group. These results suggest that the WE-3 may reduce elevated levels of serum and liver lipid contents in rat fed high fat diet.

To investigate the antihyperglycemic and antihyperlipemic effect of 80% ethanol extract of Schizandra Chinensis fruit, we induced diabetes in the rats with streptozotocin (STZ) and administered schizandra extract or Acarbose to diabetic rats for 21 days by oral administration. Consequently, the groups treated using schizandra extract decreased blood glucose levels more 39% than no treatment group and the case of Acarbose group was decreased it about 21%. The concentration of cholesterol, triglyceride and LDL-C in blood was also decreased while treating schizandra extract, on the other hand, HDL-C concentration was significantly increased it about 26%. Those results induced that anti-atherogenic index (AAI) in blood was improved more than 82% level like normal condition, especially in treatment of schizandra extract 100 mg. The lipid profiled in feces was likewise showed apparent tendency to decrease and food efficiency ratio of diabetic rats was became higher for treatment with schizandra extract, but Acarbose group had low efficiency in compared with the result of glucose level and lipid profile in blood. As a result, schizandra extract is regard a good medicine for diabetes due to improve physical constitution, blood glucose and lipid level caused hyperglycemia and suggest that schizandra extract has real effects on the diabetes complication as atherosclerosis, coronary heart disease, high blood pressure.
