This study was carried out to compare the effect of smoking on dietary habits, nutrient intakes and blood lipid profiles in 173 adult male drinkers. Subjects were classified by two groups, alcohol-only and alcohol-smoking, based on their alcohol or smoking habits. The BMI of the alcohol-smoking group was significantly lower than those of alcohol-only group. In dietary habits, the alcohol-smoking group had higher irregular breakfast and dinner intakes than alcoholonly group (p < 0.05). Plant lipid intake of the alcohol-smoking group was higher than those of alcohol-only group (p < 0.05) and the vitamin C intake of the alcohol-smoking group was lower than those of alcohol-only group (p < 0.05). With regard to the diet quality evaluation of subjects, the alcohol-smoking group showed significantly lower values than alcohol-only group in the nutrient density of carbohydrate, dietary fiber, sodium, potassium, vitamin $B_6$, and vitamin C. Also, with regard to the index of nutrition quality (INQ) and the nutrient adequacy ratio (NAR), the alcohol-smoking group showed significantly lower value than alcohol-only group in vitamin C. With these results, we found that the alcohol-smoking group had lower diet quality evaluation. The results of blood analysis showed that HDL-cholesterol in the alcohol-smoking group was significantly lower than that in the alcohol-only group. In conclusion, the alcohol-smoking group had greater health risk than the alcohol-only group. Particularly, alcohol-smoking caused irregular eating patterns and unbalanced nutrition intakes compared to alcohol-only and also changed blood composition as shown in the decrease of HDL-cholesterol. Besides, the index of coronary heart disease such as AI was higher in both groups suggesting that alcohol-only or alcohol-smoking cause health problems. Since there is the limiting point in which the comparative analysis of non-drinkers and non-smokers is unable to be performed in this study, further wide research is needed on that matter.

Artemisia iwayomogi(A. iwayomogi) is a major edible vegetable in Korea. A iwayomogi containing a strong bitter taste, particularly, is known to manifest an effect on cough, abdominal pain, indigestion and bleeding. In this experiment, ethanol extract of A. iwayomogi(50mg/kg body weight) was fed to growing male Sprague-Dawley rats for four weeks in order to examine the lipid lowering effect of A. iwayomogi in the live and serum. High fat diet included 10% lard, 1% cholesterol and 0.25% sodium cholate. The administration of A. iwayomogi extract decreased serum cholesterol compared with the control. At the same time, serum triglyceride(TG) was decreased to 25%. Although atherogenic index and HTR tended to decrease, phospholipid level in the serum was shown to increase by A. iwayomogi administration. At the same token, total liver lipids were decreased to 40%. The group fed both high fat and ethanol extract showed 28% decrease of liver lipids compared with the group fed only high fat diet. On the other hand, HDL cholesteol level of high fat and extract fed group was increased to 30% compared with the non-extract-fed control. Liver TG also was decreased to about 21% in the extract fed groups. Liver phospholipids, particularly, exceeded more than double of the level of high fat control. The above results indicate than A. iwayomogi exert a strong hypocholesterolemic and hypolipidemic effect which may lead to the protection from hypertention, obesity, stroke and many other circulatory diseases.

Cholesteryl Ester Transfer Protein (CETP) mediates the transfer of cholesterol ester and triglyceride between high-density lipoprotein (HDL) and other low-density lipoproteins, therefore, it might influence HDL levels. The levels of HDL is closely related to the atherogenic diseases in human and there were several reports that the trasgenic mice expressing CETP had much worse atherosclerosis than non-expressing control one. Therefore, selective inhibitors of CETP have the potential to be used as antiatherosclerotic agents. Continued screening for potent inhibitors of CETP led to the isolation of Suberitenone B from marine sponge. Suberitenone B, sesterterpenoids of a new skeletal class have been isolated from the sponge Suberites sp. collected from King George Island the Antartic. The structure of the metabolite has been determined by NMR experiments and chemical methods.

This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

Objectives: The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) are non-invasive methods to evaluate cardiovascular disease and arteriosclerosis. This study investigated the relationship between CAVI, ABI, and factors related to arteriosclerosis. Methods: This study included 535 healthy adults who underwent health examinations in 2019. We analyzed the correlation between CAVI, ABI and clinical variables. Multiple regression analysis was performed on the independent clinical variables associated with CAVI and ABI. Results: The correlation analysis of CAVI showed that body mass index (BMI) and HDL-cholesterol (HDL-C) had a negative correlation, and the other variables had a significant positive correlation. The correlation analysis with ABI on the right side showed that age, diastolic blood pressure (DBP), gender, and LDL-cholesterol (LDL-C) had a significant positive correlation, while HDL-C had a significant negative correlation. There was no statistical significance on the left. In the multiple regression analysis, DBP, age, BMI, gender, and HDL-C were proved to be independent factors in CAVI (right) (R²=0.365); DBP, age, gender, BMI, fasting blood sugar, and total cholesterol in CAVI (left) (R²=0.357); and age, gender, DBP, and systolic blood pressure in ABI (right) (R²=0.133). There were no statistically significant factors in ABI (left). It could be inferred that smoking and drinking are determinants that play an important role in CAVI. Conclusion: CAVI showed a high correlation with gender, age, and blood pressure. A significant correlation between CAVI and serum lipid values could be observed, but this showed a low correlation coefficient. ABI showed a high correlation with age and DBP. These results support the use of CAVI and ABI as primary diagnostic devices in medical treatment.

Adiponectin (AdipoN), brain-derived nerotrophic factor (BDNF) and leptin (LeP) are mainly secreted from adipose tissue and are known to be involved in regulation of the development of obese. However, there are not many studies on the association between abdominal fat and neuropeptides such as AdipoN, BDNF and LeP. The aim of this study was undertaken to investigate the association between abdominal fat thickness, neuropeptides and cardiovascular disease (CVD) risk factors. The participants in the study were 138 male employees without CVD. This study was approved by the Institutional Review Board of Occupational Safety and Health Research Institute. Written informed consent for the participants in this study was obtained from all individuals. We obtained subcutaneous fat thickness (SFT) and visceral fat thickness (VFT) by using ultrasonography and neuropeptides levels were measured with ELISA kit according to the method suggested by kit manufacturer. The mean SFT and VFT were $1.58{\pm}0.51$ and $4.52{\pm}1.44$ cm. The mean concentrations of AdipoN, BDNF and LeP were $3.14{\pm}3.52$ ng/ml, $24.11{\pm}8.52$ pg/ml and $4.27{\pm}2.38$ ng/ml, respectively. VFT were positively correlated with total cholesterol (r=0.217, p<0.05), LDL-cholesterol (r=0.271, p<0.01), triglyceride (r=0.233, p<0.05) and insulin (r=0.338, p<0.01), but was inversely correlated with HDL-cholesterol (r=-420, p<0.01). AdipoN levels were positively correlated with HDL-cholesterol (r=0.220, p<0.05) and were inversely correlated with total cholesterol (r=-0.196, p<0.05), LDL-cholesterol (r=-0.190, p<0.05), triglyceride (r=-0.199, p<0.05), SFT (r=-0.195, p<0.05) and VFT (r=-0.412, p<0.01). However, LeP levels showed a reverse trend to AdipoN. AdipoN level was significantly higher in non-obese participants (BMI<25 kg/m), but LeP concentration was significantly higher in obese participants (BMI>25 kg/m) than in non-obese. On multiple logistic regression analysis, obese were significantly associated with AdipoN (odds ratio=0.784) and LeP (odds ratio=1.494). These results suggested that AdipoN and LeP concentrations are affected abdominal fat and that dysfunction and/or declination in the production and secretion of neuropeptides might induced ultimately obese and CVD.

Elevated serum cholesterol is a main risk factor for heart disorders. Most probiotic products administered to lower cholesterol are dairy products which are not suitable for lactose-intolerant individuals. In this study, we assessed the cholesterol-lowering efficacy of LAB isolated from traditionally fermented drinks in diet-induced rats and determine their efficacy in the production of non-dairy, probiotic formulations using papaya juice. LAB were isolated from palm wine and corn beer on MRS agar using a pour-plate technique. Identification was carried out using 16S rRNA gene sequencing. A hypercholesterolemia model in which diet-induced Wistar albino rats were assigned into four groups was established. Oral gavage was carried out for 30 days. On the 31^st day, the rats were dissected and the serum lipid profile was analyzed using biochemical kits. A 10⁶ cfu/ml of a 24-h-old culture of selected lactobacilli was used to inoculate papaya juice and incubated at 37℃. Microbial and chemical changes were assessed during papaya fermentation and after four weeks of cold storage. Two selected isolates (Pw1 and Cb4) had in vitro cholesterol reduction of > 80%. These two isolates lowered lipid profile (triglyceride, total cholesterol, LDL-c) significantly, and increased HDL-c levels (p < 0.5) in the rat sera. Phylogenetic analysis showed that Pw1 was 98.86% similar to Limosilactobacillus fermentum, while Cb4 was 99.54% similar to Enteroccocus faecium. Both strains fermented papaya juice with cell viability reaching 8.92 × 10⁸ cfu/ml and 25.3 × 10⁸ cfu/ml respectively, and were still viable after 4 weeks of cold storage.

Flavonoids contained in grapes are potent antioxidants that may protect against oxidative stress and reduce the risk of chronic diseases related with free radical damage. In this study we investigated the effect of daily grape juice supplementation on blood pressure (BP), plasma lipid profiles and the generation of free radicals in 67 healthy volunteers (29 smoker, 38 nonsmokers). The daily 480 ml of grape juice supplementation for 8 weeks resulted in a significant decrease in diastolic BP by 6.5％ in smokers and systolic and diastolic BP by 11.2 and 3.7％ in non-smokers. Plasma total cholesterol, HDL- and LDL-cholesterollevels in smokers and total cholesterol in non-smokers were significantly increased after the intervention. Plasma triglycerides and conjugated dienes were not affected by grape juice supplementation. Levels of free radical determined by reading the lucigenin-perborate ROS generating sources, decreased significantly by 18％ compared to the beginning of the study. The results indicated that the consumption of grape juice may reduce BP and free radical generation in smokers, which was possibly exerted by flavonoids. Our findings suggested that the grape juice has protective effect on chronic disease due to the overproduction of free radical in smokers.

In order to investigate the effect of smoking on serum lipid pattern and nutrient intake, the subjects, 134 smokers and 113 nonsmokers, were selected from college men student in Kwangju area. We examined the serum lipid pattern of 15 smokers and 18 non-smokers who agreed to venipunture among the subjects and also examined nutrients intake. The results obtained were as follows ; Mean concentrations of 새심 cholesterol, HDL-cholesterol and LDL-cholesterol were 187$\pm$12.1mg/dl, 41.5$\pm$1.7mg/dl, and 87.3$\pm$7.4mg/dl in smokers and 182.6$\pm$8.2mg/dl, 45.5$\pm$1.5mg/dl, and 96.3$\pm$4.3mg/dl in nonsmokers, respectively. The total energy intake was 2264kcal/day and mean constitutional rationof protein, fat and carbohydrate was 12.7 : 24.8 : 62.5 in smokes and 2287kcal/day, 14.1 :25.4 : 60.5 in nonsmokers, respctively. Mena daily intakes of calcium, iron, vitamin C and vitamin A were 612.2mg, 15.7mg, 48.2mg 2029.4 IU in smokers and 629.4mg, 15.3mg, 68.4mg 2339.1 IU in nonsmokers, respectively. Vitamin C intake was significantly different at p<0.05 between the smokers and nonsmokers. Intakes of cholesterol, SFA and MUFA were not significantly different between the two groups. Mean daily PUFA intake of smokers and nonsmokers were 5.5g and 6.9g respectively. PUFA intake was significantly different at p<0.05 between the two groups. The results of this study showed that smoking have a tendency to raise coronary heart disease occurrence in the respect of serum lipid levels and vitamin C, PUFA intake were significantly different.

An Experiment was conducted to evaluate the effects of dietary excessive chromium picolinate on growth performance, nutrient utilizability and the content of serum cholesterol, HDL cholesterol, glucose, triglyceride and non-esterified fatty acid in broiler chicks. Experimental diets based on corn-soybean meal were supplemented at 0, 800, 1,600 and 2,400 ppb chromium in the form of chromium picolinate. Each treatment had six replicates of six female chicks each (average initial weight=45.6 g). Experimental period lasted for six weeks. Excessive supplementation of chromium as chromium picolinate had no effect on body weight gain, feed intake, feed conversion and nutrient utilizability of broiler chicks. Mortality was improved with a supplementation of chromium (p < 0.05). However, serum glucose decreased as chromium level increased (p < 0.05). Up to 2,400 ppb chromium as chromium picolinate, signs of toxicity were not noticed in this study.
