Objectives: This study was aimed to clarity the relationship between the pattern of dampness-phlegm and metabolic syndrome in acute stroke patients. Methods: Three hundred fifty-nine subjects were recruited from the patients admitted to the Internal Medical Department at Kyunghee University Oriental Medical Center, Donggnk University Ilsan Oriental Medical Center, Kyungwon University Songpa Oriental Medical Center and Kyungwon University Incheon Oriental Medical Center from April 2007 to March 2008. We diagnosed dampness-phlegm by Oriental medical diagnosis and analyzed their characteristics with type of stroke, blood test result, Sasang constitution, lifestyle and metabolic syndrome. Results: I. On the demographic variables of the patients, the weight and body mass index, the rate of hypertension, diabetes mellitus, hyperlipidemia, silent infarction were significantly higher in dampness-phlegm group than in the control. 2. There was no significant difference of stroke type between the dampness-phlegm group and the control. 3. According to the blood test, the dampness-phlegm group showed higher total cholesterol, triglyceride, fasting blood sugar and lower high density lipoprotein cholesterol than the control group with statistical significance. 4. According to the Sasang constitution distribution, the rate of Tae-Eum was significantly higher in dampness-phlegm group than in the control. 5. According to lifestyle, smoking and drinking were significantly lower in the dampness-phlegm group than in the control. Otherwise, exercise and dietary habits showed no significant difference between the two groups. 6. There were much more patients diagnosed with metabolic syndrome in the dampness-phlegm group than in the control. 7. Metabolic syndrome, silent infarction and obesity showed close relationship with dampness-phlegm pattern in multivariate analysis. Conclusions: According to the analysis, the relationship between the patterns of dampness-phlegm and metabolic syndrome in acute stroke patients were clarified. These results can be utilized in the future as a basis material.

The purpose of this study was to analyze risk factors for nosocomial pneumonia in patients admitted to NS ICU, and to provide a basic data to decrease respiratory nosocomial infection rate engendered from medical environments in NS ICU. The study site was the NS ICU at a university hospital located in Seoul, Korea. The subjects were 31 patients diagnosed with nosocomial pneumonia, who were selected from the initial list of 300 potential subjects who had been a) admitted between September 1999 and January 2000, and September 2000 and January 2001, b) resided at the NS ICU over 72 hours. The diagnostic standard of nosocomial pneumonia was based on the nosocomial infection guides of C university hospital. The data were analyzed using frequencies and logistic regression analysis. The sputums obtained from the subjects were cultivated and causal viruses were separated. The results were as follows: 1. The nosocomial pneumonia rate was $10.3\%$. There were 7 types of causal viruses separated from the sputum. and the most prevalent type of virus was MRSA as $62.2\%$. 2. The factors significantly influencing the incidence of nosocomial pneumonia included age, the residential duration at the NS ICU, GCS scores, diabetes mellitus, insertion of tracheal tube and its duration, tracheostomy and its length of insertion, the use of artificial ventilator and the length of its use, and the insertion of naso-gastic tube. The most significant risk factor among these was the insertion of tracheal tube (odds ratio=18.684. $95\%$ CI=6.849-50.974), followed by the use of tracheostomy (odds ratio=15.419, $95\%$ CI=6.615-35.942), the insertion of naso-gastric tube (odds ratio=14.875, $95\%$ CI=6.396-34.595), and the use of artificial ventilator (odds ratio=13.000. $95\%$ CI=5.633­30.001). 3. Regarding the use of the mechanical aids, the insertion of tracheal tube resulted in 12.968 times increase of the nosocomial pneumonia rate, and the use of artificial ventilator lead 6.714 times increase of the nosocomial pneumonia rate. One point increase of the GCS score resulted in the 1.210 times increase of the nosocomial pneumonia rate. For patients who had tracheal tube, tracheostomy, and artificial ventilator, one day increase of their residential duration at NS ICU lead 1.073 times increase of the nosocomial pneumonia rate. 4. In terms of duration of the mechanical aid usage, one day increase in the use of artificial ventilator engendered 1.080 times increase in the nosocomial pneumonia rate. One day increase of the residential duration at the NS ICU lead 1.604 times increase in the nosocomial pneumonia rate. As one point of the GCS score increased, 0.876 times decrease of the nosocomial pneumonia rate was reported. These study findings show that the risk factors significantly influencing the incidence of nosocomial pneumonia include the use of tracheal tube, tracheostomy, naso-gastic tube, and artificial ventilator. It is recommended that nurses working at NS ICU should pay more attention to the patients with these factors as the risky group for the nosocomial pneumonia, and thus make more active efforts to provide nosocomial pneumonia prevention strategies for them. In further studies patients admitted to the different types of ICUs such as internal medicine or surgery unit ICU will be also included, and more wide investigation of nosocomial pneumonia risk factors will be conducted through one-year longitudinal follow up.

The home nursing care system is an integral part of the health care delivery system in order to meet the various needs of consummer, in particular, early discharge patient from the hospital, patient with long term care needed and the elderly. To find out the cost of home nursing care services, the home nursing care records of patients registered by home nursing care units established in public hospital with 150beds during the period of 1996 - 1997 were analyzed. The subjects were 102patients, 45 of male patients and 57 of female patients, those who live in a rural area in Kymiggi - Do The results obtained are as follows : 1. The male patients accounted for 44.1% of the total, with 45cases : group aged 60 years and more was the largest group, accounting for 79.5%. 2. The most frequent disease revealed was the osteoporosis which constitute 35.3% of the total registered patients, followed, in order, by malignant tumor, cerebrovascular disease. 3. It revealed that the cost per visit for the male was 47,764won ; the female, 46,078 won per visit. Noteworthy the cost per visit was high in the older patient. It was clearly that the gender, years of age and the cost per visit were statistically significant at 0.01 level and 0.05 level. 4. The cost per visit for the non complicated disease was slightly higher than the complicated disease, but it is not statistically significant, the cost per visit by type of disease varied, the cost per visit for COPD was the highest, followed, in order, by in malignant tumor, cancer, diabetes, osteoporosis etc. 5. It revealed that home nursing care cost for a eligible disease for home nursing care was less than the cost for hospitalization of the same disease, therefore, we expect that the home nursing care is cost efficiency. In conclusion, the home nursing care costs are needed to analyze further in comparison with the hospitalization costs for a certain disease.

Background: Proper construction of vascular access and adequate maintenance are essential for the prognosis of the hemodialysis patients. Though arteriovenous fistula using autogenous vessel is the first of choice, the incidence of arteriovenous fistula using artificial graft is gradually increasing. The aim of this study was to analyse the patency rates between autogenous and artificial fistula, among artificial graft types, according to the accompanied disease. Material and Method: A retrospective study was conducted on 186 patients who underwent 292 arteriovenous fistula operations for hemodialysis at Korea University Guro Hospital between 1996 and 2000. Mean age of the patients was 54.37 $\pm$ 12.79years, and the male: female ratio 99:87. Result: Among 292 operations, there were 156 autogenous fistula and 116 graft fistula. The other 20 operations were thrombectomy, takedown of graft, revision, and balloon dilatation. Patency rates of autogenous fistula were 92.78 $\pm$ 2.35% at 1 year and 39.03$\pm$9.08% at 5 years, and those of graft fistula were 96.09 $\pm$ 2.22% at 1 year and 16.45 $\pm$ 10.15% at 5 scars. However, there was no statistical significance between the two operations. The patients who had hypertension, diabetes or both had no statistical significance in the patency rate compared to that of patients without underlying disease. In addition, the type of graft used did not affect the patency rate. Second operation was needed in 62 patients and third operation in 31 patients, but their patency rate again had no statistical significance compared to that of the first operation. Conclusion: The patency of the artificial graft fistula was comparable to the autogenous fistula, but the patency according to types of graft need to be studied further. Furthermore, the underlying diseases did not affect the fistula patency.

Background: Occlusive complications after arterial revascularization are difficult to treat and have high recurrence rate. This study was performed to establish an effective treatment modality and to evaluate the factors affecting the occlusive complications by analysis of clinical data. Material and Method: During the period of 5 years. 33 patients (55 reoperations) were studied at the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital following 173 arterial revascularization surgeries. The clinical characteristics, operating methods, the time intervals of reoperation, used graft, and the results of treatment were evaluated retrospectively. Result: All the patients were men except one and the mean age was 63.5 years old. The mean time internal from first operation to reoperation was 11.9 months. The cause of arterial occlusive diseases were 28 atherosclerosis and 5 Burger's diseases, Associated diseases were Hypertension $(57.6\%)$, Diabetes mellitus $(33.3\%)$, heart failure $(18.2\%)$, and so on. The mean rate of reoperation was 1.67 times and the most common type of first operation was femoro-popliteal bypass grafting $(57.6\%)$. The graft that used revascularization surgery were 25 cases of PTFE and 6 case were Dacron. There was no statistical difference between two groups. The kinds of reoperations were thrombectomy in 20 cases, angioplasty 18 cases, re-bypass surgery in 13 cases, and lumbar sympathectomy in 4 cases. The results of reoperation were 15 cases of functional recovery, 7 cases of limb salvage, 5 cases of above-knee amputation. 3 cases of below-knee amputation and 3 deaths. Conclusion: The main cause of occlusive complications are occlusion of inflow or outflow artery. Treatments were different according to the first operation methods and graft used. The most frequent time of reoperation was within one year after the first operation. We believe that graft surveillance especially during the first year is very important factor in observing the patient. We can look forward to improving limb salvage rate to perform additional treatment such as radiological interventions and lumbar sympathectomy.

Disease depends on the three factors, agent, host and environment. According to history of disease, by early 1900s the case of deaths is infectious disease, in late 1900s care of infectious diseases and tremendous scale of chronic disease, i.e., heart disease, diabetes, cancers and etc, makes care of chronic diseases be a most important theme. Now, life-style of diet is being westernized and in high industry-oriented society, obesity makes attack fate remarkably increase and life-expectancy become short, so that it causes severe problem of health. Chronic disease, such as obesity, is not affected by specific agent, but depends of interaction between host and environmental factors. There is the theory of constitutional medicine in Korean Medicine. According to it, all the people have constitutional specificity and disease. Because obesity is a kind of disease, there is the corresponding constituent being apt to be fat. Oriental Medicine utilizes herb-medication, acupuncture, and massage-therapy in treating obesity. Therefore study on relationship between constituent and obesity for OPD patients of Sangji-Oriental Medicine Hospital is carried out. The results are summarized as followings. 1. 70.2% of obesity patients are Taeumin(太陰人), 26.9% of those are Soyangin(少陽人), 2.9% of thoese are Soeumin(少陰人). 2. Most cases, high value of Free Fat Acid and Triglyceride not that of Total Cholesterol and Low Density Lipoprptein is meaningful in obesity patient blood. The corelationship between lipid test and Constitution is meaningful in Triglyceride and Free Fatty Acid. 3. Obesity is not related with gene. 4. Obesity is not related with Boyak(Herb-Med : 補藥). 5. Obesity mostly happens after delivery, contraception and operation. 6. Obese Patients are apt to eat between meals, especially food of wheat flour such as a snack. 7. The aim of treating obesity is not persuit of beauty but of keeping healthy. 8. 2.2Kg of body weight is lost after 4 week-treatment. 9. Common cause of obesity is overeating of carbohydrate and lipid than meat.

This study was performed to investigate the hypoglycemic effect of pine needle extract oil against type 2 diabetes. Six-week-old male C57BL/Ks(db/db) mice were divided into four groups : negative control, pine needle extract oil low dose, high dose and positive control groups, which fed daily for 6 weeks with corn oil, pine needle extract oil 112.5 mg/kg, 450 mg/kg or metformin (150 mg/kg ), respectively. The oral administration of the pine needle extract oil resulted in the significant and dose-dependent decreases of blood glucose levels in comparison with corn oil treatment. The levels of HbAlc showed a tendency of the decrease by the high dose treatment of the pine needle extract oil and were positively correlated with blood glucose levels (r=0.5046, p=0.0023) . However, the levels of serum insulin and C-peptide were not affected by pine needle extract oil or metformin treatments. The levels of serum leptin, which is related with the insulin sensitivity, showed a tendency of the increases by pine needle extract oil treatment and were negatively correlated to blood glucose levels (r=-0.4754, p=0.0052). In conclusion, these results suggest that the pine needle extract oil have a potential for the oral anti-hyperglycemic agent and the mode of action may be related with the improvement of the insulin sensitivity through blood leptin.

Purpose: The study purposes were to describe the process of developing the Korean versions of the Six Dimension Scale of Nursing Performance (Six-D) and Student Nurse Stress Index (SNSI) and psychometric evaluation of the two measurements. Methods: This was a methodology study using a descriptive cross-sectional design with 51 nursing students in 4th year of university. Internal consistency reliability was assessed using Cronbach alphas. Construct validity was determined by exploring correlations among Six-D, SNSI, objective structured clinical examination (OSCE), self-efficacy and grade point average (GPA). Results: Internal consistency reliability of Six-D and SNSI was acceptable with Cronbach's ${\alpha}$ of .95 and .82. Correlation analysis to determine construct validity revealed that Six-D presented positive correlations with OSCE (r=.109~.272) and self-efficacy (r=.005~.161) and negative correlation with GPA (r=-.246~-.394), although all were not statistically significant. SNSI presented all negative correlations with OSCE (r= -.007~-.238), self-efficacy (r=-.246~-.394), and GPA (r=-.092~-.426) and were mostly statistically significant except OSCE. Conclusion: Six-D needs more evidence to confirm validity to predict observed clinical competency and theoretical relationships with self-efficacy and GPA. However, SNSI presented trends of expected relationships with relevant variables. Therefore, further research is recommended in testing validity of Six-D with other student populations.

Background: Neural control of airway function is through parasympathetic, sympathetic and non-adrenergic, non-cholinergic mechanisms. The autonomic nervous system controls the airway smooth muscle tone, mucociliary system, permeability and blood flow in the bronchial circulation and release of mediators from the mast cells and other inflammatory cells. The cardiovascular and respiratory autonomic efferent fibers have a common central origin, so altered cardiovascular autonomic reflexes could reflect the altered respiratory autonomic status. Therefore, we performed this study to assess the autonomic abnormality and determine the correlating factors of severity of autonomic neuropathy in patients with chronic obstructive pulmonary disease(COPD) using easily reproducible cardiovascular autonomic reflex function test. Method: The study included 20 patients with COPD and 20 healthy persons obtained on Health Promotion Center in Yeungnam university hospital. All the patients had history and clinical features of COPD as defined by the American Thoracic Society. Any patients with myocardial ischemia, cardiac arrythmia, hypertension, central or peripheral nervous system disease, diabetes mellitus, or any other diseases known to produce autonomic neuropathy, has excluded. The autonomic nervous system function tests included three tests evaluating the parasympathetic system and two tests evaluating the sympathetic system. And also all subjects were subjected to pulmonary function test and arterial blood gas analysis. Results: Autonomic dysfunction was more commonly associated with patients with COPD than healthy person The parasympathetic dysfunction was frequent in patient with COPD, but sympathetic dysfunction seemed preserved. The severity of parasympathetic dysfunction in patients with COPD was correlated with the degree of duration of disease, smoking, reductions in the value of $FEV_1$ and FVC, and arterial hypoxemia but no such correlation existed for age, type of COPD, $FEV_1$/FVC, or $PaCO_s$. Conclusion: There is high frequency of parasympathetic dysfunction associated with COPD and the parasympathetic abnormality in COPD is increased in proportion to severity of airway disease. In COPD, parasympathetic dysfunction probably does not the cause of disease, but it may be an effect of disease progression.

There is a growing recognition of the significance of $H_2S$ as a biological signaling molecule involved in vascular and nervous system functions. In mammals, two enzymes in the transsulfuration pathway, cystathionine ${\beta}$-synthase (CBS) and cystathionine ${\gamma}$-lyase (CGL), are believed to be chiefly responsible for $H_2S$ biogenesis. Genetic inborn error of CGL leads to human genetic disease, cystathioninuria, by accumulating cystathionine in the body. This disease is secondarily associated with a wide range of diseases including diabetes insipidus and Down's syndrome. Although the human CGL (hCGL) overexpression is essential for the investigation of its function, structure, reaction specificity, substrate specificity, and protein-protein interactions, there is no clear report concerning optimum overexpression conditions. In this study, we report a detailed analysis of the overexpression conditions of the hCGL using a bacterial system. Maximum overexpression was obtained in conditions of low culture temperature after inducer addition, performing low aeration during overexpression, and using a low concentration inducer (0.1 mM, IPTG) for induction. Expressed hCGL was purified by His-tag affinity column chromatography and confirmed by Western blot using hCGL antibody and enzyme activity analysis. We also report that the His tag with TEV site attached protein exhibits 76% activity for ${\alpha}-{\gamma}$ elimination reaction with L-cystathionine and 88% for ${\alpha}-{\beta}$ elimination reaction with L-cysteine compared to those of wild type hCGL, respectively. His tag with TEV site attached protein also exhibits a 420 nm absorption maximum, which is attributed to the binding cofactor, pyridoxal 5'-phosphate (PLP).
