There are many different views of the opinion that smoking decreased the HDL cholesterol. So this cross-sectional study was attempted to find the influence which smoking, alcohol and weight affect HDL cholesterol. They were two groups;smoking group(409 males) and nonsmoking group(213 males). And HDL cholesterol, triglyceride, and total cholesterol of smoking group were compaired to them of nonsmoking group. Also the variables of age, relative weight, and alcohol were compaired. The HDL cholesterol of nonsmoking group was 47.2$\pm$10.1 mg/dl and the HDL cholesterol of smoking group was 45.5$\pm$10.7mg/dl. So there were no statistical difference. As smoking was increased in amount, HDL cholesterol was decreased slightly. According as the alcohol intake increases, especially only the HDL cholesterol of the moderate alcohol intake(101-200gm/week) group was significantly increased(P<0.05). As relative weight increases, HDL cholesterol were significantly decreased(P=0.007). Smoking was not statistical difference of HDL cholesterol. Moderately alcohol intake group(101-200gm/week) were increased the HDL cholesterol(P<0.05). Only relative weight was statistically decreased the HDL cholesterol(P<0.01). Multiple regression results that relative weight and alcohol were significant variable of the level of HDL cholesterol.

Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (<50 mg/dL, n=20), medium HDL-cholesterol (50 $\leq$, < 60 mg/dL, n=39) high serum HDL-cholesterol groups (60 $\leq$ mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate: protein: fat was 57:15:28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

NonHDL cholesterol values have been suggested as a risk marker for cardiovascular disease. NonHDL cholesterol values were calculated, using a very simple measurement [nonHDL cholesterol=serum total cholesterol-HDL cholesterol]. This formula is very useful as a screening tool for identifying dyslipoproteinemias, risk assessment, and assessing the results of hypolipidemic therapy. The data from the 2009 Korean National Health and Nutrition Examination Survey were used. Analysis was done for 1,992 subjects with lipid panels (Cholesterol, HDL, LDLdirect and Triglycerides) results. We studied the relationship between nonHDL cholesterol and LDL cholesterol. As a result, nonHDL cholesterol values were plotted against the LDL direct and calculated values. The linear regression equation for nonHDL cholesterol and direct LDL cholesterol was $nonHDLchol=23.60+1.03{\times}LDLdirect$ (p<0.0001, $r^2=0.80$) in all subjects. The subjects were classified into triglyceride values. When triglycerides are below 400 mg/dL, the linear fit to LDL direct is found to be $[nonHDLchol=17.34+1.07{\times}LDLdirect]$ (p<0.0001, $r^2=0.88$) and to the Friedewald LDL calculation is $[nonHDLchol=23.10+1.02{\times}LDLcalc]$ (p<0.0001, $r^2=0.82$). For triglycerides above 400 mg/dL, the linear fit equation is $[nonHDLchol=87.57+0.92{\times}LDLdirect]$ (p<0.0001, $r^2=0.50$) and to the LDL calculated, it is $[nonHDLchol=142.70+0.50{\times}LDLcalc]$ (p<0.0001, $r^2=0.32$). This study provides examples of the utility of nonHDL cholesterol concentrations in clinical medicine.

The purpose of this study was to investigate the correlations among the anthropometry, serum lipid levels and nutrient intake in Korean female university students. The subjects were 119 female students at a university located in Incheon. This study was conducted using a self-administered questionnaire. Anthropometric data were measured and blood lipid levels were analyzed. Nutrient intake collected from 3 day-recalls was analyzed by the Computer Aided Nutritional Analysis Program. The data were analyzed by SPSS 10.0 program. Average age, height and weight of the subjects were 20.9 years, 160.1cm and 54.3kg, respectively. Average serum TG (triglyceride), total cholesterol, HDL-C (high density lipoprotein-cholesterol) and LDL-C (low density lipoprotein-cholesterol) levels of the subjects were 69.47mg/dl, 146.85 mg/dl, 50.49mg/dl and 82.52mg/dl, respectively. Average AI (atherogenic index) of the subjects was 2.03, which was in the normal range based on risk values. Average intake of most nutrients except protein, vitamin B$_1$, vitamin C and phosphorus were lower than the Korean RDA. Especially calcium and iron intakes of the subjects were under 65% of the Korean RDA. Serum TG, total cholesterol and LDL-C levels were negatively correlated with DBP (diastolic blood pressure). HDL-C/LDL-C and HDL-C/total cholesterol were positively correlated with height. Age was positively correlated with phosphorus intake. DBP of the subjects was positively correlated with calcium and iron intakes. Serum TG level was positively correlated with total cholesterol, HDL-C, LDL-C and AI, while negatively correlated with HDL-C/total cholesterol. Total cholesterol level was positively correlated with HDL-C, LDL-C and AI, while negatively correlated with HDL-C/LDL-C, HDL-C/total cholesterol. HDL-C level was positively correlated with LDL-C, HDL-C/LDL-C and HDL-C/total cholesterol, while negatively correlated with AI. LDL-C level was negatively correlated with HDL-C/LDL-C and HDL-C/total cholesterol, while positively correlated with AI HDL-C/LDL-C ratio was positively correlated with HDL-C/total cholesterol and AI. HDL-C/total cholesterol was negatively correlated with AI. Fat intake was positively correlated with total cholesterol, HDL-C level, and vitamin B$_2$ intake was positively correlated with TG, HDL-C/LDL-C. Therefore, nutrition education is necessary for female university students to promote the lipid profile and to optimize the nutritional status. (J Community Nutrition 4(3) : 151∼158, 2002)

Influences of clotrimazole on the blood cholesterol and HDL-cholesterol level were studied in rats. Rats were provided food and water ad libitum and clotrimazole and methylcellulose were gavaged for 6 days. Clotrimazole was suspended in 1% methylcellulose solution as and administered at concentration 20mg/Kg, 40mg/Kg, 60mg/Kg. Body weight gain and liver weight/body weight ratio, serum cholesterol level, serum HDL-cholesterol level, serum triglyceride level, the activity of cytochrome p450 and erythromycin demethylase were determined at 6th day. Clotrimazole decreased the body weight gain a little as compared with control group and did not show any influence on liver weight/body weight ratio. Clotrimazole increased the serum HDL-cholesterol and serum triglyceride level significantly. Clotrimazole increased the microsomal cytochrome P450 significantly and increased the erythromycin demethylase (cytochrome P450 IIIA) significantly too. It might be conclued that clotrimazole showed a little influence on body weight and increased the serum lipid, especially HDL-cholesterol level. It also increased microsomal cytochrome P450 IIIA significantly. It might be concluded that clotrimazole showed a corelative influence between HDL-cholesterol and cytochrome P450 IIIA. In these results clotrimazole can be used as an anti-atherosclerotic agent by increasing the HDL-cholesterol but it is necessary that cloreimazole will show any adverse or side action on body or not.

Objectives: In order to determine the effect of CPs, experimental studies were performed in hyperlipidemia humans. The contents of serum total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine were measured. Methods: We made a comparative study of total cholesterol, TG (triglyceride), LDL cholesterol, HDL cholesterol, AST/ALT and BUN/creatinine during one month off and on for twenty patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University from December 2002 to July 2003. Results: The following result were obtained: 1. The serum TG and total cholesterol of patients who took CPs for one month showed significant (p<0.01) decrease. 2. The serum HDL-cholesterol and LDL-cholesterol of patients who took CPs for one month showed significantly increase in HDL, and decrease in LDL (p<0.05). 3. The serum AST/ALT and BUN/creatinine of patients who took CPs for one month showed no significant effects. Conclusions: According to the results mentioned above, the effects of CPs on serum triglyceride and total cholesterol of hyperlipidemia patients were significantly confirmed for decreasing effects.

Cardiovascular disease (CVD) is one of the most common causes of death in elderly Koreans, and HDL-cholesterol is known to have a pivotal role in protecting against CVD. This study was undertaken to study the relationships between plasma HDL-cholesterol levels and dietary, anthropometric, and biochemical factors in elderly Koreans. The 102 subjects, who were over 60 years old, were classified into two groups based on their plasma HDL-cholesterol levels: a risk group with plasma HDL-cholesterol < 40mg/dl in men or HDL-cholesterol < 50mg/d1 in women, and a control group with higher HDL-cholesterol levels. The subjects' mean intakes of energy, calcium, zinc, vitamin A, vitamin $B_2$, vitamin E, and folate did not meet the Korean RDA for elderly people. Vitamin $B_2$ and folate intakes were significantly lower (p<0.l) in the risk group compared to the control group. The consumption of seaweed was significantly lower (p<0.05), and fish intake was 33% lower, in the risk group compared to the control group. Subjects in the risk group showed a higher BMI, waist/hip ratio, triceps skinfold thickness, and % body fat, compared to control subjects. Plasma triglyceride levels and values of the atherogenic index were significantly higher (p<0.00l) in risk group subjects. Significant negative correlations between HDL-cholesterol level and plasma triglyceride level (r= 0.37), and values of the atherogenic index (r=-0.74), were found. In summary, subjects with low levels of HDL-cholesterol were found to have relatively low intakes of vitamin B$_2$, folate, and seaweed, and higher levels of the CVD risk factors: body fat, plasma TG, and AI. These results suggest that plasma HDL-cholesterol levels can be modified by dietary, anthropometric, and hematological means.

Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.

Purpose : The lipid profile is a major predictive index for cardiovascular disease, but there have only been a few studies conducted on the relationship between lipid ratio and cardiovascular disease risk factors in the Korean population. To address this research gap, we investigated the association between three lipid ratios and cardiovascular disease risk factors among Korean adults. Methods : This study used data from the seventh Korea National Health and Nutrition Examination Survey conducted in 2016. Lipid ratios included triglyceride (TG)/high density lipoprotein cholesterol (HDL), total cholesterol (TC)/HDL, and low density lipoprotein cholesterol (LDL)/HDL. Cardiovascular risk factors included in this research were: systolic blood pressure $(SBP){\geq}140$, diastolic blood pressure $(DBP){\geq}90$, fasting blood sugar $(FBS){\geq}126$, $HbA1c{\geq}6.5$, body mass index $(BMI){\geq}25$, waist circumference (WC) $men{\geq}90$, $women{\geq}85$, and metabolic syndrome (MetS). A complex samples logistic regression test was performed to analyze the association between lipid ratios and cardiovascular disease risk factors. Results : 1) TG/HDL ratio had statistically significant relationships with DBP, FBS, HbA1c, BMI, WC and MetS. 2) TC/HDL ratio was correlated to SBP, DBP, FBS, BMI, WC, and MetS. 3) LDL/HDL ratio had association with BMI, WC, and MetS. Conclusion : We identified significant association between lipid ratios and cardiovascular disease risk factors. The three lipid ratios were particularly strongly associated with BMI, WC, and MetS.
