PURPOSE: The purpose of present study was to investigate effects of obesity, blood pressure and life style on lipid indices and blood pressure in men of age 40s. METHODS: One hundred forty five subjects in men of age 40s were participated in this study. All participants were taken physical examination, lifestyle survey and laboratory test. According to examination, participants were divided into two group in four categories ; obesity and normal group, hypertension and normal group, smokers and non-smokers, and drinkers and non-drinkers. The low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), total cholesterol (TC), triglyceride (TG), systolic blood pressure (SBP), diastolic blood pressure (DBP) were analyzed by independent t-test for comparison between two groups. RESULTS: The values of LDL, TC, SBP, DBP were higher and HDL was lower in obesity than in normal group (p<.05). The values of LDL, TC, SBP, DBP were higher in hypertension group than in normal group (p<.05). The values of TG was higher and HDL was lower in smokers than in non-smokers (p<.05). There's no significant differences between drinkers and non-drinkers (p>.05). CONCLUSION: It can be seen that obesity and blood pressure were more relative risk factors than smoking and alcohol indices in cardiovascular diseases.

The purpose of this study was to establish a baseline in order that individuals may exercise safely. Sixty healthy students who were divided into two groups participated in the experiment. One group exercised both arms and legs at 60 rpm and the other at 90 rpm. There was a significant difference between arm and leg exercise in diastolic blood pressure (DBP) and time to target heart rate (tTHR). DBP decreased more in the upper (U//E) than the lower extremity (L/E), but tTHR increased more in the L/E than the U/E (p < 0.05). Systolic blood pressure (SBP) was similar for both arm and leg exercise (p > 0.05). There was also no significant difference between 60 rpm and 90 rpm in SBP, DBP or tTHR in either arm or leg exercise (p > 0.05). In conclusion, the slope of the linear increase in heart rate was steeper for U/E than L/E work. Therefore L/E exercise is safer than U/E exercise.

The level of plasticizer such as diethyl phthalate (DEP), di-n-propyl phthalate (DprP), di-n-butyl phthalate (DBP), di-n-pentyl phthalate (DPP), butylbenzyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), dicyclohexyl phthalate (DCHP) and di-(2-ethylhexyl) adipate (DEHA) was determined in disposable sanitary gloves. Samples of disposable sanitary gloves were taken at retail shops, and their overall extractions in carbon tetrachloride were measured, after establishment of soxhlet appratus in 6 hours. All of 8 samples of disposable sanitary gloves at retail shops were polyethylene (PE). All of the manufactures was voluntarily labelled their boxes of gloves in line Korea Food Code. The level of phthalate esters and DEHA in all of 8 samples were not exceed the detection limit. The detection limits of DEP, DprP, DBP, DPP, BBP, DEHP, DCHP and DEHA were 1.8, 1.9, 1.3, 1.1, 0.9, 0.7, 2.1 and 0.8 mg/L, respectively.

Correlations of adolescents' blood pressure with dietary factors and blood or urinary electrolytes were investigated in this study. Through the screening for blood pressures of 960 middle school students aged 13-16 years, 30 students with the mean value of SBP and DBP above 96th percentile(high blood pressure group) and the other 30 with the mean blood pressure between 48th and 52th percentiles(normal blood pressure group) were selected as the subjects. SBP/DBP of the high and talc normal blood pressure groups were $141.8{\pm}9.0$ / $83.6{\pm}5.1$ mmHg and $116.4{\pm}3.5$ / $69.8{\pm}3.7 mmHg$, respectively. The average values of age, weight, height, BMI, degree of relative crude physical activity, and family income were not different between two groups. Among nutrients for which intakes were determined by 24 hour-recall and expressed as percent RDA, intakes of total and animal calcium were lower in the high blood pressure group compared to the normal, and were negatively correlated with both SBP and DBP even when the effects of related general and other dietary factors were excluded. Whereas energy, total, animal and vegetable protein, total and animal lipid, and riboflavin were higher in intake in the high blood pressure group than in fille normal, and they were in positive correlations with SBP and/or DBP. Vitamin A and ascorbic acid intakes were also negatively correlated with DBP, though ascorbic acid intake was not different between two groups. High blood pressure group preferred higher concentration of thin rice gruel than normal group and talc preferred salt concentrations was ill positive correlation with SBP. Serum and urinary levels of Ca, Mg, Ca/Mg ratio, Na, K and Na/K ratio did not show any differences between two groups. However serum Ca/Mg retio was in negative and se겨m Mg was ill positive correlations with SBP, and urinary Na excretion was negatively correlated with SBP. Calcium intake showed negative correlation with serum Ha and Na/K ratio. Our data indicated that dietary intake of Ca, energy, protein, lipid, vitamin A and C as well as salt preference were associated with blood pressure in adolescents. It might be assumed that Ca lowered blood pressure by increasing serum Ca/Mg ratio and decreasing serum Ca/K ratio though urinary excretion of Na.

BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have been reported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologic studies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as well as sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sectional analysis of a prospective cohort baseline survey was performed with 6,283 subjects (2,443 men and 3,840 women) and free of hypertension, diabetes, cardiovascular diseases, and cancer. Dietary data were collected by trained interviewers using food frequency questionnaire. RESULTS: The significantly inverse linear trend of diastolic blood pressure (DBP) was found in fruits and non-pickled vegetables (81.2 mmHg in the lowest quintile vs 79.0 mmHg in the highest quintile, P for trend = 0.0040) and fruits only (80.9 mmHg in the lowest quintile vs 79.4 mmHg in the highest quintile, P for trend = 0.0430) among men. In contrast, sodium and sodium to potassium ratio were positively related with blood pressure among men (DBP, 78.8 mmHg in the lowest quintile vs 80.6 mmHg in the highest quintile, P for trend = 0.0079 for sodium; DBP, 79.0 mmHg in the lowest quintile vs 80.7 mmHg in the highest quintile, P for trend = 0.0199 and SBP, 123.8 mmHg in the lowest quintile vs 125.9 mmHg in the highest quintile for sodium/potassium). Kimchies consumption was positively related to DBP for men (78.2 mmHg in the lowest quintile vs 80.9 mmHg in the highest quintile for DBP, P for trend = 0.0003). Among women, these relations were not found. CONCLUSION: Fruits and/or non-pickled vegetables may be inversely, but sodium, sodium to potassium, and Kimchies may be positively related to blood pressure among men.

Hypertension is the most prevalent disease worldwide and is itself a risk factor for cerebral, cardiac, and renal diseases. The inconsistency of candidate genes suggested by previous genomewide association studies (GWASs) may be due to not only differences in study design and genetic or environmental background but also the difference in the power of analysis between continuous traits and discrete traits. We analyzed 352,228 single nucleotide polymorphisms (SNPs) in 8842 unrelated Koreans obtained from Ansan and Ansung cohorts. We performed a series of GWA analyses using three different phenotype models; young hypertensive cases (278 subjects) versus elderly normotensive controls (680 subjects); the upper 25% (2211 hypertensive cases) versus the lower 25% of the SBP distribution (2211 hypotensive controls); and finally SBP and DBP as continuous traits (8842 subjects). The numbers of young hypertensive cases and elderly normotensive controls were not large enough to achieve genomewide significance. The model comparing the upper 25% subjects to the lower 25% of subjects showed a power that was approximate to that of QTL analysis. Two neighboring SNPs of the ATP2B1 gene, rs17249754 (SBP, p=$2.53^{-10}$; DBP, p=$1.28{\times}10^{-8}$) and rs7136259 (SBP, p=$1.30{\times}10^{-9}$; DBP, p=$6.41{\times}10^{-8}$), were associated with both SBP and DBP. Interestingly, a SNP of the RPL6 gene, rs11066280, revealed a significant genomewide association with SBP in men only (p=$3.85{\times}10^{-8}$), and four SNPs located near the MAN2A1 gene showed a strong association with DBP only in elderly men aged 60-70 years (e.g., rs6421827, p=$4.86{\times}10^{-8}$). However, we did not observe any gene variant attaining genomewide significance consistently in the three phenotype models except for the ATP2B1 gene variants. In general, the association signal with blood pressure was stronger in women than in men. Genes identified in GWASs are expected to open the way for prevention, early diagnosis, and personalized treatment of hypertension.

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.

The purpose of this study was to investigate effects of 12-weeks finswimming exercise on electroencephalogram(EEG), SBP, DBP, and RHR in male adolescents. Eighteen male adolescents participated in this study. They were separated into a Control group(CG; n=9) and Finswimming training group(FG; n=9). FG participated in Finswimming training for 12weeks, 60 minutes per day, 3 times a week. All data of electroencephalogram were analyzed by repeated measures two-way ANOVA and Data of SBP, DBP and RHR were analyzed by ANCOVA and Paired t-test. As a result, Alpha and SMR waves were significantly increased in FG; however, Alpha wave was significantly decreased in CG and Theta wave was significantly decreased in FG. There were significant interaction in Alpha, Theta, and SMR waves. SBP, DBP, and RHR were significantly decreased in FG and there were significant differences of RHR and SBP between groups; otherwise, there were no significant differences of DBP between groups. The results of this study showed that 12 weeks of Finswimming training positively effects on electroencephalogram(EEG), SBP, DBP, and RHR in male adolescents.

PVDF membrane formation via TIPS was performed for PVDF/DBP and PVDF/DMP systems. PVDF/DBP system showed solid-liquid phase separation behavior, while PVDF/DMP system has liquid-liquid phase separation characteristic as well as solid-liquid phase separation characteristic. PVDF contents and cooling conditions had great influence on structure, and the effects of each parameter were examined. Spherulitic structure was obtained due to the dominant PVDF crystallization. Diluent rejected to the outside of spherulite occupied the surface of the PVDF spherulites to result in the microporous spherulite formation and micro-void between spherulites. PVDF/DMP system had competitive solid-liquid and liquid-liquid phase separation depending on the cooling path.
