  • The purpose of this study was to develop a web-based internet program for nutritional assessment and diet management of patient having hyperlipidemia. Hyperlipidermia were classified by hypercholesterolemia and hypertriglyceridemia. The program consisted of four parts according to their functions and contents. The first part explained the metabolism of lipids and defined the hyperchotesterolemia and hypertriglyceridemia. The second part is to assess the general health status such as body weight, obesity index, basal metabolic rate and total energy requirement by the input of age, sex, height, weight and degree of activity. This part also provides the Patient with menus lists and 1 day menu suitable to his weight, activity and the status of hyperlipidemia and offers the information for food selection, snacks, convenience foods, dine-out, behavioral modification, cooking methods, food exchange lists, and information on energy and nutrients of foods and drinks, and top 20 foods classified by nutrients. The third part is designed to investigate diet history of patient, that is, to find out his inappropriate dietary habit and give him some suggestions for appropriate dietary behavior. This part also offers on-line counseling and frequently asked Questions. The fourth part is evaluating their energy and nutrients intake by comparing with recommended dietary allowance for Koreans or standardized data for patient with hyperlipidemia. In this part, it is also analyzing energy and nutrients of food consumed by food group and meals, and evaluating the status of nutrient intake. These results are finally displayed as tabular forms and graphical forms on the computer screen.

  • Lovastatin is a lipid lowering agent for the treatment of hypercholesterolemia and belongs to a new class of pharmacologic compounds called the 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors. By competitively inhibiting HMG CoA reductase, lovastatin disrupts the biosynthesis of cholesterol in hepatic and peripheral cells and increases the synthesis of high-density-lipoprotein HDL) receptors. Following oral administration, the lactone ring of lovastatin is hydrolysed to the active inhibitor of HMG CoA reductase, lovastatin acid. Lovastatin is known to have poor oral absorption and wide individual variation. In this study, bioequivalence test of two lovastatin formulations, the test drug ($Lovaload^{TM}$, Chong Kun Dang Pharmaceutical Co.) and the reference drug ($Mevacor^{TM}$, Chung Wae Pharmaceutical Co.) were conducted according to the guidelines of Korea Food and Drug Administration (KFDA). A total of 18 healthy male volunteers, $31.90\pm3.60$ years old and $72.17\;7.88$ kg of body weight in average, were evaluated in a randomized crossover manner with a 2-week washout period. Concentrations of lovastatin acid in plasma were measured upto 12 hours following a single oral administration of eight tablets (20 mg of lovastatin per tablet) by high-performance liquid chromatography with UV detection at 238 nm. The area under the concentration-vs-time curve from 0 to 12 hours $(AUC_{0-12h})$ was calculated by the trapezoidal summation method. The statistical analysis showed that there are no significant differences in $AUC_{0-12h),\;C_{max}\;and\;T_{max}$ between the two formulations ($6.72\%,\;1.52\%,\;and\;0.88\$, respectively). The least significant differences between the formulations at $\alpha$=0.05 were less than $20\%\;(11.65\%,\;19.73\%,\;and\;14.81\%\;for\;AUC_{0-12h},\;C_{max}\;and\;T_{max}$, respectively). The $90\%$ confidence intervals for these parameters were also within $\pm20\%\;(-1.50{\leq}{\delta}{\leq}15.00$, $-12.50{\leq}{\delta}{\leq}15.50,\;and\;-9.64{\leq}{\delta]{\leq}11.40{\leq}\;for\;\;AUC_{0-12h}$ ,$C_{max}\;and\;T_{max}$, respectively). In conclusion, the new generic product $Lovaload^{TM}$ was proven to be bioequivalent with the reference drug.

  • Objectives: This study examined the effects of nutrition education focused on personalized daily energy requirement and food units using Food Exchange System on anthropometric, biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes for overweight and obese in a public health center. Methods: The subjects were 60 overweight/obese women based on BMI (educated 30 vs. non-educated 30, 50~64 years). Educated group was provided individual and/or group lessons (40 min/lesson/week, 5 week), 'Introduction: obese & health', '6 nutrients and 6 food groups', 'My obesity & daily needed energy', 'Meal planning for personalized daily energy and food units using Food Exchange Systems', and 'Smart food choices'. After education, we examined the differences in anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes between educated group and non-educated group. Results: After nutrition education, in the educated group, there were improvements on anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes in the educated group compared to the non-educated group. We observed a decrease in the mean weight, total cholesterol (TC) and the incidence of overweight/obesity and hypercholesterolemia and an increase in the mean lean body mass. The scores of nutrition knowledge, 'Function of carbohydrate, protein, vitamin, mineral' and 'Food Sources of fat, vitamin, mineral' were increased. The scores of dietary attitudes, 'Taking a joyful meal, a leisurely meal, a balanced meal, a meal with sufficient vegetables, a meal with diversity, a meal with spicy foods, a meal with overeating' were increased. The intakes of energy, carbohydrate, fat, protein, vitamin A, thiamin, Zn and cholesterol were decreased. The scores of INQ, protein, vitamin A, vitamin C, thiamin, riboflavin, vitamin B6, folate, Ca, P, Fe, Zn were increased. Conclusions: The nutrition education focused on personalized daily energy requirement and food exchange unit using Food Exchange System for overweight and obese may improve food behavior, dietary intakes and symptoms of overweight and obese, even in a community health center.

  • This study was designed to observe the effects of the feeding Platycodon grandiflorum, Codonopsis Ianceolata, perilla oil and safflower oil on the fatty acid composition in serum and liver of dietary hypercholesterolemic rats. Experimental groups mixed with 5% cellulose +10% lard (group 1, control group), 2% cholestyraemine +10% lard (group 2), 5% C. ianceolata+ 10% perilla oil (group 3), 5% P. grandiflorum+10% perilla oil (group 4), 5% C. ianceolata+10% safflower oil (group 5) and 5% P. grandiflorum+10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. In the fatty arid compositions of serum total fatty arid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was most in the PUFA and it was major fatty acid. Particularly, the other components except the phospholipid fraction in serum lipids were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid content was remarkably more in the groups 5 and 6. In the fatty arid compositions of liver total fatty acid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was more in the PUFA and so it was major fatty acid. Particularly, the arachidonic and eicosapentaenoic acid contents of phospholipid fraction in liver lipids were rather more. from the above research, fatty arid composition of serum and liver lipid components were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid takes up the highest percentage.

  • We examine the effect of Geiji-Bokryung-Hwan(GBH) on erectile function in a rat model of hypercholesterolemic erectile dysfunction. GBH, a drug preparation consisting of five herbs of Cinnamomi Ramulus (Geiji), Poria Cocos (Bokryun), Mountan Cortex Radicis (Mokdanpi), Paeoniae Radix (Jakyak), and Persicae Semen (Doin) is a traditional Korean herbal medicine that is widely used in the treatment of atherosclerosis-related disorders. In this study, 3-month-old Sprague-Dawley rats were used. The 6 rats control animals were fed a normal diet and the other 18 rats were fed 1% cholesterol diet for 3 months. After 1 months, GBH was added to the drinking water of the treatment group of 12 rats but not the cholesterol only group of 6 rats. Of the 12 rats 6 received 30 mg/kg per day (group 1) and 6 received 60 mg/kg per day (group 2) of GBH. At 3 months erectile function was evaluated with cavernous nerve electrostimulation in all animals. Penile tissues were collected for electron microscopy, and to perform Western blot for endothelial nitric oxide synthase (eNOS), neuronal nitric oxide synthase (nNOS), basic fibroblast growth factor (bFGF) and caveolin-1. Systemic arterial pressure was not significantly different between the animals that were fed the 1% cholesterol diet and the controls. Conversely erectile function was not impaired in the herbal medicine treated rats. Electron microscopy showed many caveolae with fingerlike processes in the cavernous smooth muscle and endothelial cell membranes in control and treated rats but not in the cholesterol only group of rats. Western blot showed differences among groups in protein expression for eNOS, nNOS, caveolin-1 and bFGF protein expression in penile tissue. Increased eNOS and nNOS protein expressions dy high cholesterol diet were significantly decreased in group 1 and group 2. Interestingly, caveolin-1 and bFGF protein expression was significantly higher in groups 1 and 2 than in the cholesterol only and control groups.

  • Purpose: This study evaluated the glycemic response of diets using estimated glycemic load (eGL), which had been developed for mixed meals for Korean adults, and examined its associations with cardiometabolic risk factors among Korean adults. Methods: A total of 4,655 men and 6,760 women aged 19 years and above were included from the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey. eGL was calculated by each meal (breakfast, lunch, dinner, and snack) and then summed to give daily total eGL. A multiple logistic regression analysis was used to examine the association. Results: Mean daily total eGL was 112.6 in men and 99.3 in women. Daily total eGL was positively associated with carbohydrate and fiber intakes, but negatively associated with protein and fat intakes in both men and women (p < 0.05 for all). Daily total eGL showed an inverse association with HDL-cholesterol level in both men and women (p = 0.0036 for men and p = 0.0008 for women). Men in the highest quintile of daily total eGL showed a 66% increased risk of hypercholesterolemia (OR, 1.66; 95% CI, 1.10 ~ 2.50; p for trend = 0.0447) compared with those in the lowest quintile. Conclusion: These findings suggest that eGL based on carbohydrate, protein, fat and fiber intakes can reflect glycemic response and therefore can be used as an index for dietary planning, nutrition education and in the food industry.

  • This study selected 2,134 fertile women aged 20 to 44 years as the final study subjects using the 6th source data of the National Health and Nutrition Survey. The purpose of this study was to investigate the relationship between female characteristics, chronic diseases and oral health behavior, and the effects of each factor on periodontal diseases. There were statistically significant differences in age(p<0.001), education level(p<0.001), income(p<0.05), marital status(p<0.001), smokes(p<0.05) and pregnancy(p<0.001). Chronic disease factors showed statistically significant differences in hypertension(p<0.001), obesity(p<0.001), diabetes(p<0.001), hypercholesterolemia(p<0.05), hypocholesterolemia(p<0.001) and hypertriglyceridemia(p<0.001). Oral health behaviors were statistically significant in terms of toothache(p<0.05), orthodontic treatment(p<0.05) and chew discomfort(p<0.05). As a result of examining the risk factors affecting periodontal disease, the risk of chronic disease was 1.576 times higher in the obese group, and 2.569 times higher in the diabetic group than in the normal group. The subjective oral health status was 1.372 times higher for normal women and 1.614 times higher for bad women than for good ones. As a result, diabetes has shown the greatest risk among chronic diseases in women, and diabetes and obesity are highly relevant and therefore are considered important variables for the risk factors of dementia. In this regard, it is necessary to examine the risks of chronic and periodical diseases, expand oral health education programs for women's dental disease, and prepare oral health policies.

  • The effects of medium-chain enriched diacylglycerol (MCE-DAG) oil on hepatic cholesterol homeostasis were investigated. HepG2 hepatocytes were treated with either 0.5, 1.0, or $1.5{\mu}g/mL$ of MCE-DAG for 48 h. There was no evidence of cytotoxicity by MCE-DAG up to $1.5{\mu}g/mL$. The level of proteins for cholesterol uptake including CLATHRIN and LDL receptor increased by MCE-DAG in a dose-dependent manner (p<0.05). Furthermore, proprotein convertase subtilisin/kexin type 9, an inhibitor of LDLR, was dose-dependently diminished (p<0.05), indicating cholesterol clearance raised. MCE-DAG significantly increased 3-hydroxy-3-methylglutaryl-coenzyme A reductase and acetyl-CoA acetyltransferase2 (p<0.05), required for cholesterol synthesis, and their transcriptional regulator sterol regulatory element-binding protein2 (p<0.05). These findings suggest that given conditions of prolonged sterol fasting in the current study activated both hepatic cholesterol synthesis and clearance by MCE-DAG. However, total intracellular level of cholesterol was not altered by MCE-DAG. Taken together, MCE-DAG has the potential to prevent hypercholesterolemia by increasing hepatic cholesterol uptake without affecting intracellular cholesterol level.

  • Hempseed, a dehulled Cannabis fructus, has high nutraceutical potential. It has plenty of essential amino acids, vitamins, and essential polyunsaturated fatty acids, including α- and γ-linolenic acid. Increased exercise capacity, cognitive function, and ameliorative effects against hypercholesterolemia, neuro-inflammation, thrombus formation, and learning and memory impairment were reported in hemp-seed oil-administered models. Therefore, the market prices of hempseed oil are 45~140-fold higher than the other plant-derived oils, such as soy, corn, olive, canola, or linseed oil. In this study, instead of FTIR (Fourier Transform Infrared Spectroscopy) or FTIR-Raman spectroscopy, a simple UV-Vis spectrophotometry method was developed to authenticate the hempseed oil. Measurements of absorbance at 245, 305, and 415 nm of oils and calculations of 245/415 and 315/415 nm provided that the ratios of 245/415 and 315/415 nm of authentic hempseed oils were 12.9 and 9.6, respectively. The 245/415 and 315/415 nm of soy oil, corn oil, canola oil, and linseed oil were 35.4~61.8 and 29.7~50.8, respectively. This simple UV-Vis spectrophotometry method could also be applied to differentiate hempseed oil from blended oil products in markets.

  • Purpose: Quercetin is a polyphenolic flavonoid abundant in many fruits and vegetables. It has potential health-beneficial properties, such as antioxidant, anti-obesity, anti-cancer, anti-diabetic and anti-inflammatory effects. The purpose of this study was to investigate whether the lipid metabolism improvement effect of quercetin affected the regulation of AMP-activated protein kinase (AMPK) activity and microRNA (miR)-21 expression in the liver of mice fed a high-cholesterol diet. Methods: Male C57BL/6J mice were fed with normal diet, quercetin-free diet and diets containing 0.05% or 0.1% quercetin for six weeks. Hypercholesterolemia was induced by adding 1% cholesterol and 0.5% cholic acid to all diets. Serum and liver triglyceride (TG), and total cholesterol (TC) concentrations were analyzed using a commercial enzymatic colorimetric kit. AMPK activity was quantified using an AMPK kinase assay kit. The levels of miR-21 and genes involved in lipid metabolism were measured by real-time quantitative polymerase chain reaction. Results: Supplementation of quercetin reduced serum and hepatic TG and TC levels without changing body weight and food intake. Dietary quercetin significantly inhibited the mRNA levels of hepatic sterol-regulatory element binding protein-1c, acetyl-CoA carboxylase 1 and fatty acid synthesis, which are involved in hepatic lipogenesis. Dietary quercetin enhanced AMPK activity and suppressed miR-21 expression, promoting hepatic lipid accumulation. Conclusion: These results suggest that the lipid-lowering effect of quercetin on the serum and liver of mice may be partially mediated by the regulation of lipogenic gene expression, AMPK activity and miR-21 expression in the liver of mice fed a high-cholesterol diet.
