Background and Purpose : The purpose of this study was to investigate that which symptoms are adequate indicator of the Dampness-Phlegm pattern in the stroke patients. Methods : In the time period Jul. 2005 to Sep. 2006, 136 patients with a first-ever stroke admitted in the department of Internal Medicine of Daejeon University Oriental Medical Hospital in Daejeon city, Wonkwang Oriental Medical Hospital in Iksan, JeonJu city were included. Patients were hospitalized within 3 months after the onset of stroke. Stroke patients had been interviewed by resident who studied standard operation procedures in Fundamental Study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. Gi-deficiency patients was confirmed by medical specialist diagnosis, resident diagnosis, case report form analysis without a dissenting voice. Results : Dampness-Phlegm group included 37 case, Non Dampness-Phlegm group 45 case out of 136 patients. white tongue coating, slippery purse, yellowish complexion, enlarged tongue, swollen tongue were higher among Dampness-Phlegm group. Dampness-Phlegm and Non Dampness-Phlegm patients do not significantly differ in heavy sensation in the head, voice with sputum, teeth printed tongue, borborygmus, dizziness with nausea. Conclusions : This study was insufficiency because sample size is very small. More data from prospective cohort studies will help to Korean Standard Differentiation of the Symptoms and Signs for the Stroke.

BACKGROUND/OBJECTIVES: Glutathione S-transferase (GST) forms a multigene family of phase II detoxification enzymes which are involved in the detoxification of xenobiotics by conjugating substances with glutathione. The aim of this study is to assess the antioxidative status and the degree of DNA damage in the subclinical hypertensive patients in Korea using glutathione S-transferase polymorphisms. SUBJECTS/METHODS: We examined whether DNA damage and antioxidative status show a difference between GSTM1 or GSTT1 genotype in 227 newly diagnosed, untreated (systolic blood pressure $(BP){\geq}130mmHg$ or diastolic $BP{\geq}85mmHg$) subclinical hypertensive patients and 130 normotensive subjects (systolic BP < 120 mmHg and diastolic BP < 80 mmHg). From the blood of the subjects, the degree of the DNA damage in lymphocyte, the activities of erythrocyte superoxide dismutase, the catalase, and the glutathione peroxidase, the level of glutathione, plasma total radical-trapping antioxidant potential (TRAP), anti-oxidative vitamins, as well as plasma lipid profiles and conjugated diene (CD) were analyzed. RESULTS: Of the 227 subjects studied, 68.3% were GSTM1 null genotype and 66.5% were GSTT1 null genotype. GSTM1 null genotype had an increased risk of hypertension (OR: 2.104, CI: 1.38-3.35), but no significant association in GSTT1 null genotype (OR 0.982, CI: 0.62-1.55). No difference in erythrocyte activities of superoxide dismutase, catalase, or glutathione peroxidase, and plasma TRAP, CD, lipid profiles, and GSH levels were observed between GSTM1 or GSTT1 genotype. Plasma levels of ${\alpha}-tocopherol$ increased significantly in GSTT1 wild genotype (P < 0.05); however, plasma level of ${\beta}-carotene$ increased significantly in GSTT1 null genotype (P < 0.01). DNA damage assessed by the Comet assay was significantly higher in GSTM1 null genotype than wild genotype (P < 0.05). CONCLUSIONS: These results confirm the association between GSTM1 null genotype and risk of hypertension as they suggest that GSTM1 null genotype leads to an increased oxidative stress compared with wild genotype.

The aim of this study was to examine the relationship between dietary variables and the prevalence of insulin resistance (IR) in middle-aged Korean adults using data from the 2007-2009 Korea National Health and Nutrition Examination Survey. Because IR is closely linked with metabolic syndrome, subjects were divided into three groups according to symptoms of metabolic syndrome: the 'Normal group' without any symptoms, the 'Risk group' with one or two symptoms, and the Metabolic syndrome (MetS) group' with three or more symptoms. Subjects between the ages of 30 and 65 years with no prior diagnosis or treatment for diabetes, hypertension, or dyslipidemia were selected. The number of subjects per group was as follows: 2,085 adults in the Normal group, 3,699 adults in the Risk group, and 1,160 adults in the MetS group. Metabolic syndrome was defined according to Adult Treatment Panel III criteria with modified waist circumference cutoff values (men ${\geq}$ 90 cm, women ${\geq}$ 85 cm). Subjects with HOMA-IR > 2.0 were classified as IR. Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) was calculated using the following formula: (fasting plasma glucose ${\times}$ fasting plasma insulin)/22.5. Nutrients and food groups intake were obtained from a single 24-hour recall. Subjects with IR in the Normal group were more obese and less physically active than non-IR subjects. In the MetS group, subjects with IR were more obese and had a lower prevalence of smoking and drinking, compared with non-IR subjects. Men with IR in the Normal group had a tendency to consume more oils and sugars than non-IR men, while women with IR in the same group had higher intake of carbohydrate, dietary glycemic index, and dietary glycemic load than non-IR women. Women with IR in the Risk group had lower energy intake but higher intake of oils and sugars than non-IR women. In the MetS group, consumption of fruits was higher in subjects with IR than in non-IR subjects. In conclusion, findings of this study suggest that dietary carbohydrate intake, including glycemic index, may be associated with IR in healthy women. Further research in prospective cohort studies in order to examine the effects of dietary carbohydrate on IR incidence will be necessary.

The aim of this study was to identify the correlation between low density lipoprotein (LDL) cholesterol and the pulmonary function. This study enrolled premenopausal women in their aged 40s, who visited the health promotion center of a general hospital more than two times. A total of 384 subjects were classified into four groups based on their LDL-cholesterol levels; A, LDL(mg/dL)<100 at both initial and follow-up; B, LDL<100 at initial but ${\geq}100$ at follow-up; C, $LDL{\geq}100$ at initial but <100 on follow-up; and D, $LDL{\geq}100$ at both the initial and follow-up test. The result showed no significant differences in the pulmonary function between the four groups. Multiple linear regression analysis, which was adjusted for age, body mass index, smoking, exercise, and follow-up duration, showed a significant negative relationship between the changes in the LDL and the changes in the $FEV_1/FVC$ (${\beta}=-0.109$, S.E.=0.029, P<0.001), but not in the $FEV_1$ and FVC. In conclusion, there was a significant but weak relationship between the LDL and pulmonary function. Further larger studies will be needed.

Purpose: This study examined the association of fruit and vegetable consumption with asthma in Korean adults. Methods: Data on 16,528 adults aged 19-64 were collected from the Korea National Health and Nutrition Examination Survey (KNHANES). The general characteristics of the subjects, daily food intake, and daily energy and nutrients intake were investigated according to fruit and vegetable consumption. All statistical analyses were conducted based on SAS software version 9.4. Results: The prevalence of doctor-diagnosed asthma was 2.6%, and ranged between 1.8% and 3.1% depending on fruit and vegetable consumption. As fruit and vegetable consumption increased, the individuals showed a higher average age and household income, but a lower educational level, smoking rate, and frequency of alcohol consumption. The group with higher fruit and vegetable consumption had higher intakes of all food groups without milk and dairy products and energy and nutrients than the counterpart group. For the intake rate of energy, the group with higher consumption of fruit and vegetables had a higher intake rate of carbohydrate and protein and a lower intake rate of fat. The risk rate of asthma with the third quartile group regarding fruit and vegetable consumption was 35%-40% lower than that of the first quartile group. Conclusion: The results suggest that adequate consumption of fruit and vegetable will help to improve the risk of asthma. Moreover, prospective cohort studies and clinical test research are necessary to measure the effects of fruit and vegetable consumption on the occurrence of asthma.

Wornen's lahor market participation as well as the policy concern for wider utilization of married women, have continuously grown up. However, research efforts on the determinants of women's labor market participation, in the context of the relationship hetween life courses and active entry into lahor market, has been far behind the growing interest in this field. This study has conducted an event histoiry analysis of women's labor market transition utilizing personal occupational history data collected by the Korea Institute for Women's Development in 1991. The analysis is divided into tow parts: First part introduces logit regression to analyze the determinants of women's labor market participation and exit. The second part employs Cox regression to see the variation of transition rate between employment and non-employment. The result shows that there is a wide variation in women's labor market participation according to age, cohort, and family formation. Special note is needed for the significantly negative effect of marriage and child birth on labor market participation. The transition pattern of lower class women with less education fits well to the prediction of neo-classical economics; but the tendency of highly educated women's regression to non-employment reveals the strong influence of the unfavorable labor market structure, which can be better explained by the neo-structuralist perspective. There is a strong trade-off between productive and reproductive labor of women, which can only be corrected by strong policy implementation, such as extended child care facilities, abolition of discriminatory employment practices, and expansion of flexible part-time employment.

Korea National Statistical Office(KNSO) estimated period birth rates, period death rates, and probability of dying for infant(q$q_{0}$) at period life table, considering the unregistered infant deaths. As Ministry of Health and Welfare(MHW) conducted 1993 and 1996 birth cohort infant death surveys. KNSO re-estimated infant mortality levels(especially q$q_{0}$). For the re-estimation, reference data were derived from death registration. MHW surveys, death registration of developed countries. Model Life Tables, and Life Table for Japan. Seventeen simulations were made by the combination of estimation methods and reference data. The final $q_{0}$ was estimated based on the relationship between $q_{0}$ of MHW 1993 survey and $q_{1-4}$ of registered deaths for the period of 1971~1997. For 1993, $q_{0}$ was calculated directly from the 1993 MHW survey and interpolation and extrapolation were made for 1995 and 1997 using the relative decrease rates of $q_{0}$ between 1993 and 1996 MHW surveys. Utilizing the formular of Coale-Demeny North Model, $q_{0}$ was transformed into $m_{0}$ for the period 1971~1997. Finally, cremation data are found to be very useful for the estimation of 1998 infant mortality level by supplementing unregistered infant deaths, especially neonatal deaths. Furthermore, they are found to be very useful to produce fetal and perinatal death statistics.

A case-control study was conducted to investigate the relationship between blood cadmium, blood zinc and cadmium/zinc ratio and hypertension. Eighty-three hypertensive and seventy-seven normotensive study subjects matched for age and sex were selected from the workers who had no history of job-related cadmium exposure, in Ulsan city and it's vincinity, Korea. The blood cadmium in hypertensive group was $2.90{\eta}g/mL$, which was significantly higher than that of control group, $1.99{\eta}g/mL$(P<0.01). After stratifing for smoking and age variables, the relationship was still remained. The blood cadmium/zinc ratio in hypertensive group was 2.46, which was significantly higher than that of control group, 1.65(P<0.01), After stratifing for smoking and age variables, the relationship was still remained. There was no significant differance in blood zinc between hypertensive and control group. On multiple logistic regression analysis, the blood cadmium/zinc ratio is highly significant than blood cadmium. In conclusion, there is the possible relationship between blood cadmium level which has been known to be within normal limits and hypertension. But, futrher cohort studies to define the effect of cadmium on human hypertension are required.

DNA ploidy is an important prognostic parameter in paediatric B-ALL, but the significance of the S-phase fraction is unclear. In present study, DNA ploidy was assessed in 40 pediatric B-ALL cases by flow cytometry. The DI (DNA index) and percentage of cells in S-phase were calculated using Modfit software. Aneuploidy was noted in 26/40 (65%) cases. A DI of 1.10-1.6 (hyperdiploidy B) was noted in 20/40 (50%) and 6/40 (15%) had a DI>1.60 (triploid and tetraploid range). Some 14/40 (35%) cases had a diploid DI between 0.90-1.05. None of the cases had a DI <0.90 (hypodiploid) or in the 1.06-1.09 (hyperdiploid A) range. The mean S-phase fraction was 2.6%, with 24/40 (60%) having low and 16/40 (40%) high S-phase fractions. No correlation was noted with standard ALL risk and treatment response factors with DI values or S-phase data, except for a positive correlation of low S-phase with high NCI risk category (p=0.032). Overall frequency of hyperdiploidy in our cohort of B-ALL patients was very high (65%). No correlation between hyperdiploidy B and low TLC or common B-phenotype was observed in our study as 42% cases with DI 1.10-1.6 had TLC> $50{\times}10^9$ and 57.1% CD 10 negativity. The study also highlighted that S-phase fraction analysis does not add any prognostic information and is not a useful parameter for assessment in ALL cases. However, larger studies with long term outcome analysis are needed to derive definitive conclusions.

Background: The response to treatment and overall survival (OS) of patients with acute myeloid leukemia (AML) is variable, with a median ranging from 6 months to 11.5 years. TP53 is associated with old age, chemotherapy resistance, and worse OS. Using genetic sequencing, we set out to look at our own experience with AML, and hypothesized that both TP53 mutations and SNPs at codon 72 would mimic the literature by occurring in a minority of patients, and conferring a worse OS. Materials and Methods: We performed a pilot study of randomly selected, newly diagnosed AML patients at Mount Sinai Medical Center, diagnosed from 2005-2008 (n=10). TP53 PCR sequencing was performed using DNA from bone marrow smears. Analysis was accomplished using Mutation Surveyor software with confirmation of the variants using the COSMIC and dbSNP databases. Results: Fewer than half of the patients harbored TP53 mutations (40%). There was no significant difference in OS based on gender, AML history, risk-stratified karyotype, or TP53 mutation. There were possible trends toward improved survival among patients less than 60 (11 vs 4 months, p=0.09), Hispanics (8 vs 1 months, p=0.11), and those not harboring SNP P72R (8 vs 2 months, p=0.10). There was a significant improvement in survival among patients with better performance status (28 vs 4 months, p=0.01) and those who did not have a complex karyotype (8 vs 1 months, p=0.03). The most commonly observed TP53 mutation was a missense N310K (40%) and the most commonly observed SNP was P72R (100.0%). Conclusions: Our study confirms previous reports that poor PS and the presence of a complex karyotype are associated with a decreased OS. In our cohort, TP53 mutations were relatively common, occurring more frequently in male patients with an adverse karyotype. Although there was no significant difference in survival between TP53 mutated and un-mutated patients, there was a possible trend toward worse OS among patients with SNP P72R. Larger studies are needed to validate these findings.
