BACKGROUND/OBJECTIVES: Few epidemiological studies examined the association between fried food intake and hypertension. This study examined whether fried food intake was associated with higher prevalence of prehypertension and hypertension combined in a cross-sectional study of the Filipino Women's Diet and Health Study (FiLWHEL). SUBJECTS/METHODS: This study included a total of 428 women aged 20-57 years who have ever been married to Korean men. Prehypertension was defined as 120 - < 140 mmHg of SBP or 80 - < 90 mmHg of DBP and hypertension as SBP ≥ 140 mmHg or DBP ≥ 90 mmHg. Fried food intake was assessed using one-day 24-hour recall. Fried foods were categorized into total, deep/shallow and pan/stir fried foods. The odds ratio (OR)s and 95% confidence interval (CI)s were calculated using multivariate logistic regression. RESULTS: The prevalence of prehypertension and hypertension combined was 41.36% in this population. High fried food intake was associated with high prevalence of prehypertension and hypertension combined. The odds of having prehypertension and hypertension was higher in the 3rd tertile of fried food intake among fried food consumers compared to non-fried food consumers (OR = 2.46, 95% CI = 1.24, 4.87; P for trend = 0.004). Separate analysis for types of frying showed that deep and shallow fried food intake was associated with prevalence of prehypertension and hypertension combined for comparing the 3rd tertile vs. non-fried food consumers (OR = 2.93; 95% CI = 1.57-5.47; P for trend = < 0.001). CONCLUSIONS: This study showed the evidence that high fried food intake was significantly associated with high prevalence of prehypertension and hypertension combined among Filipino women married to Korean men.

This study analyzed the fabric and product size of the burn patient's custom compression garment and measured the pressure applied by the garment to assess whether proper pressure is being delivered for treatment. The test clothes were presented to the market by body size and commissioned with the same design. The subjects selected four people close to the average body size of men in their 20s determined by 7th Size Korea. The experiment was conducted by wearing a compression suit, performing activities and measuring changes in the pressure of the garment according to changes in posture. The fabric used for the compressive clothing was not ruptured even at 216 kPa, the elasticity recovery rate was measured between 80.5 and 94.5%. The product dimensions of the experimental clothing varied by up to 8cm from brand to brand, requiring the standardization of compression clothing. The experiment showed that four types of compression suit varied in pressure, and the pressure range, excluding the gastric arm (17.9mmHg), was between 2.5-14.1mmHg, which failed to meet the level of pressurization for treatment purposes. The clothing pressure in the chest area dropped when performing movements rather than standing still. This was interpreted to be a result of reduced the adhesion of the compression suit during operation. The peak pressure (31.68mmHg) and the lowest pressure (2.2mmHg) was noted in the scapula, indicating that no pressure was being transmitted on the vertebrae. The pressure of the garment on the right shoulder blade was elevated in a supine position. Because much time is spent laying down, it is necessary for the pattern design to accommodate for the increased clothing pressure on the shoulder blades. Standardization of the level of pressurization for burn patient's custom-made pressure suits for each stage of treatment is urgently required.

Objectives: Previous studies have shown that periodic limb movements in sleep (PLMS) could be one of risk factors for cardiovascular morbidity. The purpose of this study was to investigate the association between PLMS and blood pressure changes during sleep. Methods: We analyzed data from 358 adults (176 men and 182 women) aged 18 years and older who were free from sleep apnea syndrome (Respiratory Disturbance Index < 5) and sleep disorders such as REM sleep behavior disorder or narcolepsy. Demographic characteristics, polysomnography records, and clinical variable data including blood pressure, body mass index, alcohol, smoking, and current medications were collected. In addition, self-report questionnaires including the Beck Depression Index, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index were completed. Blood pressure change from bedtime to awakening was compared between the two periodic limb movement index (PLMI) groups [low PLMI ($PLMI{\leq}15$) and high PLMI (PLMI > 15)]. Blood pressure change patterns were compared using repeated measures analysis of variance. Results: Systolic blood pressure in the high PLMI group was lower than that in the low PLMI group (p = 0.036). These results were also significant when adjusted for gender and age, but were not statistically significant when adjusted for BMI, alcohol, smoking, anti-hypertension medication use and sleep efficiency (p = 0.098). Systolic blood pressure dropped by 9.7 mm Hg in the low PLMI group, and systolic blood pressure in the high PLMI group dropped by 2.9 mm Hg. There was a significant difference in delta systolic blood pressure after sleep between the two groups in women when adjusted for age, BMI, alcohol, smoking, antihypertensive medication use and sleep efficiency (p = 0.023). Conclusion: PLMS was significantly associated with a decreasing pattern in nocturnal BP during sleep, and this association remained significant in women when adjusted for age, BMI, alcohol, smoking, antihypertension medication use and sleep efficiency related to blood pressure. We suggest that PLMS may be associated with cardiovascular morbidity.

Mercury-resistant ($Hg^R$) bacteria were isolated from heavy metal polluted wastewater and soil collected near to tanneries of district Kasur, Pakistan. Bacterial isolates AZ-1, AZ-2 and AZ-3 showed resistance up to $40{\mu}g/ml$ against mercuric chloride ($HgCl_2$). 16S rDNA ribotyping and phylogenetic analysis were performed for the characterization of selected isolates as Bacillus sp. AZ-1 (KT270477), Bacillus cereus AZ-2 (KT270478) and Bacillus cereus AZ-3 (KT270479). Phylogenetic relationship on the basis of merA nucleotide sequence confirmed 51-100% homology with the corresponding region of the merA gene of already reported mercury-resistant Gram-positive bacteria. The merE gene involved in the transportation of elemental mercury ($Hg^0$) via cell membrane was cloned for the first time into pHLV vector and transformed in overexpressed C43(DE3) E. coli cells. The recombinant plasmid (pHLMerE) was expressed and the native MerE protein was obtained after thrombin cleavage by size exclusion chromatography (SEC). The purification of fusion/recombinant and native protein MerE by Ni-NTA column, dialysis and fast protein liquid chromatography (FPLC/SEC) involved unfolding/refolding techniques. A small-scale reservoir of wastewater containing $30{\mu}g/ml$ of $HgCl_2$ was designed to check the detoxification ability of selected strains. It resulted in 83% detoxification of mercury by B. cereus AZ-2 and B. cereus AZ-3, and 76% detoxification by Bacillus sp. AZ-1 respectively (p < 0.05).

Foods constitute a large portion of heavy metal exposure toward general population and attract a deep concern with respect to assuring human health. This study summarized published data in Korea on the content, and dietary intake of heavy metals and assessed their risk potential in comparison with foreign data. An analysis for the yearly fluctuation of metal contents including arsenic, cadmium, mercury and lead by flood group (marine fishes, coastal shellfishes, freshwater fishes, cereal grains) exhibited a decreasing trend from the 1970s to the 1990s. When compared with domestic standards of heavy metals, their mean contents were below the limit and their maximum values seldom exceeded the limit. The data on the dietary intake of heavy metals by Koreans showed a decreasing trend from the 1980s to the 1990s. The average intakes offs and Hg were 6∼8% and those of Cd and Pb were 50∼80% of PTWI(provisional tolerable weekly intake), all of which were below the tolerance. As the extreme intakes of these metals may exceed the PTWI, a careful assessment for them may be necessary. Dietary intakes of Cd, Hg and Pb by Koreans lie in the mid-level among countries cited in the GEMS/Food monitoring data. As fishery foods are suspecious of contamination with Hg, Cd and As, and floods in general are with Pb, it is necessary to establish legal limits for these metals and monitor any progress of their contamination. Furthermore, overall assessment of exposure to heavy metals from all sources including floods, air, drinking water and occupation should be made in order to confirm the dietary risk factors and to assure the safety of food resources.

Mercury Iodide as good sensitivity at radiation and has an easy peculiarity that operates at low voltage for other photoconductors(a-Se, a-Si, Ge, etc) Based on this characteristic, we studied about an efficiency of the digital x-ray detector in acccordance with the thickness of photoconductor. To solve the problem that is difficult to make a large area film using PVD(Physical Vapor Deposition)method, we used a PIB(Particle In Binder)method. To make a binder paste, we used a PVB(Polyvinylbutyral) as a binder and a DGME(Diethylene Glycol Monobutyl Ether), DGMEA(Diethylene Glycol Monobutyl Ether Acetate) as a solvent. Using this binder paste, we made a polycrystal mercury iodide film that has an each thickness. To evaluate the electrical properties of this films, we measured a darkcurrent, sensitivity and SNR(Signal to Noise Ratio). Mercury iodide film of the 200um thickness has good electrical properties as a result of the measurement. From this result there is a good chance that replace the existing a-Se(Amnorphous seleinum; a-se) with the mercury iodide.

This study was carried out to discover the effects of eating habits and health-related life style on blood pressure, $\gamma$-Glutamic acid Peptide Transferase($\gamma$-GPT), blood glucose and High Density Lipoprotein-Cholesterol(HDL-C). 185 subjects(85 male, 100 female) were selected, who were living in the Cheonju area aged 40#s to 60#s. The mean systollic blood pressure(SBP), diastollic blood pressure (DBP), $\gamma$-GPT, fasting blood sugar(FBS) and HDL-C for all the subjects were 118mmHg, 77mmHg, 281U/l, 90mg/dl and 45mg/dl, respectively. The SBP and DBP for subuects over 60 years old were 126mmHg and 81mmHg and were significantly higher than subjects in their 40#s and 50#s(p<0.001, p<0.005). The HDL-C of the group that rarely ate breakfast was 57mg/dl and that was significantly higher than the 44mg/dl scored by those who ate breakfast everyday(p<0.05). The SBP for subjects having a snack 2-3 times/week was 125mmHg and that was significantly higher than the 114mmHg of those having a snack everyday(p<0.05). The $\gamma$-GPT for subjects consuming alcohol everyday was 44IU/L and that was significantly higher than 18IU/I of the non-drinking group(p<0.001). The $\gamma$-GPT of light smokers was 53IU/I and that was significantly higher than the 22IU/I for non-smoking participants(p<0.001). The DBP, SBP, $\gamma$-GPT, FBS and HDL-C related to exercise not significantly different. The SBP(p<0.001) and DBP(p-0.01) between age group was positively correlated. The $\gamma$-GPT between drinking frequency(p<0.001), drinking quantity(p<0.05), and smoking(p<0.05) was also positively correlated. The FBS between exercises had a negative correlation(p<0.05), and the HDL-C between breakfast had a negative correlation(p<0.05). These results indicate that decreasing drinking and smoking, when combined with appropriate exercise, will decrease the $\gamma$-GPT and fasting blood sugar level, and help preventing adult diseases.

A 9-month-old castrated male French Bulldog (13 kg of body weight) was presented with the primary complaint of loud heart murmur and exercise intolerance. Diagnostic imaging studies found severe pulmonic stenosis (peak velocity > 5 m/s) with right ventricular hypertrophy. Because of higher pressure gradient between right ventricle and right ventricular outflow tract (> 100 mmHg), the dog was underwent balloon valvuloplasty through femoral vein. After procedure, the peak pulmonic velocity was reduced to 2.1 m/s (PG = 18 mmHg). Further follow-up study found no further deterioration, for 6 months to date. This is the first case report of pulmonic stenosis treated by transvenous balloon valvuloplasty through femoral vein in Korea.
