Thrombolysis using urokinase solution is one of the effective methods in treatment of intracerebral hematoma. The present study was undertaken in order to 1) determine the most effective concentration of urokinase solution, 2) determine the most suitable time interval of irrigation of urokinase solution through the measurement of hemoglobin and FDP(Fibrin / Fibrinogen Degradation Product) of drained solution, 3) estimate the size of unresolved hematoma without taking brain CT. The results are summarized as follows : 1) The most effective and economic concentration of urokinase solution was 1000 u/ml. 2) The most preferable time interval of irrigation of urokinase solution was about one hour. 3) It was possible to estimate the size of unresolving hematoma by means of measurement of hemoglobin and hematocrit of patient, hemoglobin and volume of the thrombolysed solution, so that it was unnecessary to take brain CT for measurement of remaining hematoma.

OBJECTIVES: We wanted to investigate the relationship between job stress and liver dysfunction in Korean male white collar workers. METHODS: A total of 700 male white collar workers who worked at one electronic institute and who participated in an annual surveillance program were recruited: 664(94.9%) workers were initially recruited and the data for 36 workers was excluded due to poor responses and a past history of liver disease. The questionnaire survey included the participants' general characteristics, the job-related factors, the health-related behaviors and job stress. Job stress was assessed using the Korean Occupational Stress Scale-Short Form (KOSS-SF). We merged the job stress data with the individual liver function results by conducting annual surveillance. Multiple logistic regression analysis with adjusting it for the confounding variables, including alcohol drinking and the body mass index (BMI), was used to evaluate the relationship between job stress and liver dysfunction. RESULTS: After adjustment for the confounding variables, the proportion of liver dysfunction cases was significantly higher in the groups with a high level of job stress, as assessed by the 'job demands and total score'. After conducting a stratified analysis with considering alcohol drinking and the BMI, the prevalence odds ratio of liver dysfunction was higher in the groups with a high level of job stress, as assessed by the 'job demands and total score'. CONCLUSIONS: The results of this study suggest that the level of job stress (and especially that assessed by the job demands and total score) is related to liver dysfunction. Thus, further preventive efforts and studies are needed to reduce job stress and address liver dysfunction.

OBJECTIVES: The objectives of this study were to determine the relationship between lifestyle-implementation and metabolic syndrome in an electronics research and development company, and to provide a foundation for health providers of health management programs for setting priorities. METHODS: From July 1 to July 16, 2008 we carried out a descriptive cross-sectional survey. Consecutive workers of one R & D company in Seoul, Korea (N=2,079) were enrolled in study. A checklist for lifestyle (from the National Health Insurance Corporation) consisted of questions regarding diet, drinking, smoking and exercise. After the survey, researchers obtained data from health profiles for metabolic syndrome(waist-circumference, triglycerides, HDL cholesterol, blood pressure and fasting blood sugar level). Lifestyle was recorded as good or not good. Statistical analysis of metabolic syndrome and the lifestyle of subjects was done using multiple logistic regression analysis. RESULTS: The prevalence of metabolic syndrome in our study gropu was 13.3% (N=277). After adjustment for age, the adjusted odds ratios (odds ratio, 95% confidence intervals) for metabolic syndrome increased in proportion to the number of bad habits: two (1.72, 1.23-2.44), three (2.47, 1.73-3.56), and four (3.63, 2.03-6.34). Relative to subjects eating both vegetables and meat', the OR for 'meat' eaters was 1.66 (1.18-2.31). Compared with 'non-smokers and ever-smoker', the OR for 'current-smoker' was 1.62 (1.25-2.10). Compared with 'Healthy drinker', the OR for 'unhealthy drinker' was 1.38 (1.05-1.83). CONCLUSIONS: Poor lifestyle was associated with an increased likelihood of metabolic syndrome. These findings suggest that lifestyle-based occupational health interventions for young employees should include a specific diet, smoking cessation, and healthy-drinking programs.

r cells, and the efficacy of drug delivery can be high in richly vascularized tumors. So, this study was conducted to evaluate the effect of neoadjuvant chemotherapy on microvessel density from 11 patients with tongue cancers. Our results showed that neoadjuvant chemotherapy was seemed to decrease VEGF expression in tumor cells, however, it did not significantly alter VEGF expression in tumor-associated macrophages. Also, Neoadjuvant chemotherapy had little effect on the microvessel density using CD34, and tumor-associated macrophage level using CD68. Thus, tumorassociated macrophages seem to be the key factor associated with the maintenance of microvessel density after neoadjuvant chemotherapy in tongue cancer.

PURPOSE: This study analyzed the prognostic factors affecting the survival rate and evaluated the role of radiation therapy in muscle-invading bladder cancer. MATERIALS AND METHODS: Twenty eight patients with bladder cancer who completed planned definitive radiotherapy in the Departments of Therapeutic Radiology and Urology, Chonnam National University Hospital between Jan. 1986 to Dec. 1998 were retrospectively analyzed. The reviews were performed based on the patients' medical records. There were 21 males and 7 females in this study. The median of age was 72 years old ranging from 49 to 84 years. All patients were confirmed as having transitional cell carcinoma with histological grade 1 in one patient, grade 2 in 15, grade 3 in 9, and uninformed in 3. Radiation therapy was performed using a linear accelerator with 6 or 10 MV X-rays. Radiation was delivered daily with a 1.8 or 2.0 Gy fraction size by 4 ports (anterior-posterior, both lateral, alternatively) or 3 ports (Anterior and both lateral). The median radiation dose delivered to the isocenter of the target volume was 61.24 Gy ranging from 59 to 66.6 Gy. The survival rate was calculated by the Kaplan-Meier method. Multivariate analysis was performed on the prognostic factors affecting the survival rate. RESULTS: The survival rate was 76%, 46%, 33%, 33% at 1, 2, 3, 5 years, respectively, with 19 months of median survival. The potential factors of age (less than 70 years vs above 70), sex, diabetes mellitus, hypertension, hydronephrosis, T-stage (T3a vs T3b), TUR, chemotherapy, total duration of radiotherapy, radiation dose (less than 60 Gy vs above 60 Gy), and the treatment response were investigated with uni- and multivariate analysis. In univariate analysis, the T-stage ( p=0.078) and radiation dose ( p=0.051) were marginally significant, and the treatment response ( p=0.011) was a statistically significant factor on the survival rate. Multivariate analysis showed there were no significant prognostic factors affecting the survival rate. CONCLUSION: The treatment response and radiation dose are suggeted as the statistically significant factors affecting the survival rate of muscle invasive bladder cancer. A Further prospective randomized study is needed to confirm these prognostic factors.
