The aim of this study was to evaluate the effect of kale (Brassica oleracea acephala) juice supplementation on serum lipid levels and phospholipid (PL) fatty acid compositions in hypercholesterolemic men. Thirty-two men with hypercholesterolemia (>200 mg/dl) were recruited among the faculty and staff at Y University after annual health examinations. The subjects consumed 150 ml of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed before and after supplementation, respectively, to ensure that the subjects maintained their usual diet and lifestyle throughout the intervention. Serum concentrations of HDL-cholesterol and the ratio of HDL-cholesterol to LDL-cholesterol were significantly increased (p<0.001) after intervention. Serum LDL-cholesterol concentration and atherogenic index were significantly reduced (p<0.001). Levels of 12:0, 14:0, $18:1{\omega}9$, $18:3{\omega}6$, and sum of monounsaturated fatty acids (MUFA) in serum pholspholipid (PL) were significantly increased, while $22:4{\omega}6$ level was significantly reduced (p<0.05). It can be speculated that kale juice, containing large amounts of antioxidant nutrients, contributes to changes of serum-PL-fatty acid compositions and the improvements of serum lipid profiles. This study demonstrates the supplementation of regular meals with kale juice may favorably affect serum lipid profiles and serum-PL fatty acid compositions and, hence, could lower the risks of coronary artery disease in men with hypercholesterolemia.

The Kasai portoenterostomy is the first-line treatment for the restoration of the flow of bile to the small intestine in patients with biliary atresia. Various complications can occur after Kasai portoenterostomy, including ascending cholangitis, biliary cirrhosis, and portal hypertension. Of these potential complications, ascending cholangitis in the most common. In cases of patients having uncontrolled complications due to progressive liver cirrhosis, portal hypertension, or progressive hyperbilirubinemia, liver transplantation is the indicated as treatment plan. Lifelong follow-up, particularly involving imaging studies, is important for the identification of various complications arising from biliary atresia after Kasai portoenterostomy. Additionally, imaging studies play a crucial role in the evaluation of potential liver donors and recipients. US is a key imaging modality utilized in the management of patients who undergo Kasai portoenterostomy, while CT and MRI are imperative to obtaining an accurate diagnosis.

Present study was conducted to investigate the effects of exercise and cholesterol diet on plasma and liver lipids, platelet aggregation, erythrocyte Na efflux and liver index such as GOT and GPT using Sprague Dawley rats. Forty rats were divided into four groups and fed control or 0.5% cholesterol diet with and without treadmill for six weeks. The final body weight of group fed cholesterol diet with exercise was somewhat decreased compared with group fed cholesterol diet without exercise. L.W/B.W ratio was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise tended to decrease this ratio. Plasma total cholesterol was significantly increased and HDL-cholesterol was decreased in groups fed cholesterol diet (p < 0.01). Plasma triglyceride was significantly decreased in groups fed cholesterol diet compared with groups fed control diet (p < 0.01). Plasma triglyceride of groups with exercise was significantly decreased compared with their non exercising counterparts regardless diet (p < 0.05). Liver total cholesterol and triglyceride was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise did not affect on these levels. Na-K ATPase was somewhat decreased in groups fed cholesterol diet, and exercise tended to recover the reduced Na-K ATPase. Na passive transport was significantly decreased in group fed control diet without exercise and significantly increased in group fed cholesterol diet with exercise, there were significant differences between groups (p < 0.05). There were no differences in total Na efflux and intracellular Na among groups, and total Na efflux was not correlated with intracellular Na. Hematocrit was significantly lower (p < 0.05) in group fed cholesterol diet without exercise compared with other groups. Platelet aggregation in the initial slope and the maximum was increased in groups fed cholesterol diet, but not statistically significant. Exercise especially increased the initial slope of aggregation. Plasma GOT and GPT was significantly increased in groups fed cholesterol diet (p < 0.01), and exercise in group fed cholesterol diet significantly decreased both GOT and GPT compared with the non exercising counterpart (p < 0.01). This study showed that cholesterol diet increases plasma and liver lipids and GOT and GPT, and exercise improves plasma and liver lipid profile and liver index of GOT and GPT preventing fatty liver.

Experimental trials of unilateral lung transplantation in dogs have been attempted and satisfactory results were obtained without any noticeable difficulty in surgical techniques. Fourteen dogs with the body weight of around 25 kg were anesthesized by 20~30 mg/kg of intravenous Entobar,; one was sacrificed to make available blood for use during transplantation for the recipient dog. A mid-sternotomy incision was performed and 20 mg/kg of Prostaglandin E1 was infused through the pulmonary artery and Euro-Collin's(E-C) preservation solution, cooled down to 4$^{\circ}C$, was perfused at the rate of 70cc/kg by a pressure of 30 cmH2O. The heart-lung block was then resected out and promptly immersed in the prepared preservation solution at 4$^{\circ}C$. One lung preserved in the EC solution at 4$^{\circ}C$ was anastomosed to the recipient dog in the order of the pulmonary vein, bronchus then pulmomary artery and the thoracotomy incision was closed after the bleeding control and tube thoracostomy. Then the pneumonectomy in the opposite side was perfomed in the same manner and the tailored lung was transplanted in the order of the pulmonary vein, bronchus, then pulmonary artery. We conclude that in the bilateral sequential lung transplantation, the right lung transplantation should precede to better expose the operative field and to prevent reperfusion injury; also, the cardiopulmonary bypass should be consider for certain appropriate cases.

Objectives : High-normal blood pressure' is a factor influencing decision to initiate targeted intensive intervention strategy in westernized populations. JNC-VI offered the vigorous lifestyle modification for persons with 'high-normal blood pressure', who could be early detected. As a hypertension seems to be the result of multiple genetic factors operating in concert with associated environmental factors, it will be necessary to identify the high-normal blood pressure as a risk factor of hypertension for applying primary prevention strategy in Korean people. Methods : Although cohort study design might be adequate to recruit incidence cases, to keep time sequence of events, and to prevent information bias, nested case-control study was chosen for avoiding measurement errors because hypertension is a benign disease. Source population was the 'Seoul Cohort' participants and follow-up was done by using Korea Medical Insurance Corporation's database on the utilization of health services from 1 Jan93 to 30Jun97. Incidence cases were ascertained through the chart review, telephone contacts, and direct blood pressure measurements. Controls included the pairing of 4 individuals to each case on the basis of age. Results : As 75% of 247 incident cases had high-normal blood pressure, the crude odds ratio for hypertension was 2.04 (95% CI 1.47-2.83). Another statistically significant risk factors of hypertension were body mass index, dietary fiber, alcohol consumption, weekly activity and history of quitting smoking. The multivariate odds ratio of high-normal blood pressure adjusted for all risk factors was 1.84 (95% CI 1.31-2.56). Among high-normal blood pressure group, body mass index, weekly ethanol amounts, weekly physical activity, and dietary fiber except history of quitting smoking were still risk factors of hypertension. Conclusion : 'High-normal blood pressure' is a risk factor for hypertension in Korean middle-aged men, which represents that the vigorous lifestyle modification for persons with 'high-normal blood pressure' is need.

Extracorporeal membrane oxygenation (ECMO) provides mechanical cardiopulmonary support and has been used for children with severe respiratory failure, intractable heart failure, sepsis, pulmonary hypertension, and as a bridge to heart transplantation. There have been few reports of the use of ECMO to provide cardiac support in children with low cardiac output as a result of arrhythmias. We report the case of a 15-year-old female with circulatory collapse due to refractory ventricular arrhythmia after one and a half repair in Ebstein's anomaly, who was successfully resuscitated using ECMO.

Purpose : The long term disease course and prognostic factors were evaluated in childhood Henoch-$Sch{\ddot{o}}nlein$ puruura nephritis(HSPN). Methods : A total of 75 children(44 boys and 31 girls) with HSPN were included in this study. The onset age was $8.0{\pm}3.1$ years(2.3-l5.3 years), and the follow-up period was $4.3{\pm}3.6$ years(1.0-17.1 years). Kidney biopsy was done in 24 children(32$\%$). Initial clinical and laboratory findings were evaluated. In addition, polymorphisms of the renin angiotensin system(RAS) genes(insertion/deletion in intron 16 of ACE gene, M235T in AGT gene, and A1166C in AGTR gene) were analysed. The initial and last clinical states were classified into 4 groups as follows A, normal; B, minor urinary abnormalities; C, active renal disease (nephrotic-range proteinuria and/or hypertension with serum creatinine $\leq$1.5 mg/dL); D, renal insufficiency. Results : At the onset, the clinical states of the patients were B in 26(35$\%$), C in 46(61$\%$), and D, in 3(4$\%$). The distribution of the RAS gene polymorphism of HSPN were not different from that of 100 healthy control subjects. At the last follow-up, the clinical states of the patients were A in 23(31$\%$), B in 38(50$\%$), C in 9(12$\%$), and D in 5(7$\%$). A multiple logistic regression identified age at the onset and initial urine protein excretion as significant prognostic factors. Analysis of genotypes of the 3 RAS genes as prognostic values revealed no statistical significance. Conclusion : Older age at onset and severe proteinuria were identified as poor prognostic factors of childhood HSPN. Implication of the RAS gene polymorphism In HSPN could not be validated in this small-scale retrospective study. (J Korean Soc Pediatr Nephrol 2005;9:183-192)

Purpose : Vesicoureteral reflux(VUR) is known to be the main cause of childhood hypertension and renal failure. Knowing its familial occurrence, we determined the incidence of VUR and renal scar in asymptomatic siblings of Korean patients with primary VUR Methods : A total of 50 siblings from 37 index patients were included. Voiding cystourethro-graphy(VCUG) and renal scintigraphy using $^{99m}Tc-DMSA$ were peformed in these siblings from June, 1994 to May, 2001, Index patients were classified into two groups according to the presence of VUR in their siblings, and the clinical factors of the index patients such as age, sex, grade of reflux and renal cortical defect were compared between the groups. Results : Among the 50 siblings, VUR were found in 8(16%) and renal cortical defects were detected in 8(16%) siblings respectively. The incidence of renal cortical defects was 87.5%(7 out of 8) in the VUR(+) siblings. There was a case of VUR(-) cortical defect in one sibling, presumed as a scar from an old VUR. There was no relationship among age, sex, grade of reflux and renal cortical defect of the index patient to the presence of VUR in siblings. Conclusion : This study confirmed a significant incidence of VUR(16%) and renal cortical defects(16%) in the asymptomatic siblings of patients with primary VUR in Korea. It Is resonable to recommend screening studies to the siblings of patients with VUR for the early detection and prevention of probable reflux nephropathy.

Purpose : Although the average life expectancy has increased due to advances in medicine, mortality due to cancer is on an increasing trend. Consequently, the number of terminally ill cancer patients is also on the rise. Predicting the survival period is an important issue in the treatment of terminally ill cancer patients since the choice of treatment would vary significantly by the patents, their families, and physicians according to the expected survival. Therefore, we investigated the prognostic factors for increased mortality risk in terminally ill cancer patients to help treat these patients by predicting the survival period. Methods : We investigated 31 clinical parameters in 157 terminally ill cancer patients admitted to in the Department of Family Medicine, National Health Insurance Corporation Ilsan Hospital between July 1, 2000 and August 31, 2001. We confirmed the patients' survival as of October 31, 2001 based on medical records and personal data. The survival rates and median survival times were estimated by the Kaplan-Meier method and Log-rank test was used to compare the differences between the survival rates according to each clinical parameter. Cox's proportional hazard model was used to determine the most predictive subset from the prognostic factors among many clinical parameters which affect the risk of death. We predicted the mean, median, the first quartile value and third quartile value of the expected lifetimes by Weibull proportional hazard regression model. Results : Out of 157 patients, 79 were male (50.3%). The mean age was $65.1{\pm}13.0$ years in males and was $64.3{\pm}13.7$ years in females. The most prevalent cancer was gastric cancer (36 patients, 22.9%), followed by lung cancer (27, 17.2%), and cervical cancer (20, 12.7%). The survival time decreased with to the following factors; mental change, anorexia, hypotension, poor performance status, leukocytosis, neutrophilia, elevated serum creatinine level, hypoalbuminemia, hyperbilirubinemia, elevated SGPT, prolonged prothrombin time (PT), prolonged activated partial thromboplastin time (aPTT), hyponatremia, and hyperkalemia. Among these factors, poor performance status, neutrophilia, prolonged PT and aPTT were significant prognostic factors of death risk in these patients according to the results of Cox's proportional hazard model. We predicted that the median life expectancy was 3.0 days when all of the above 4 factors were present, $5.7{\sim}8.2$ days when 3 of these 4 factors were present, $11.4{\sim}20.0$ days when 2 of the 4 were present, and $27.9{\sim}40.0$ when 1 of the 4 was present, and 77 days when none of these 4 factors were present. Conclusions : In terminally ill cancer patients, we found that the prognostic factors related to reduced survival time were poor performance status, neutrophilia, prolonged PT and prolonged am. The four prognostic factors enabled the prediction of life expectancy in terminally ill cancer patients.

In an attempt to avoid the adverse effects of the cardiopulmonary bypass, off pump coronary artery bypass grafting(Off pump CABG) that has recently been rediscovered and refined. We compared the preoperative risk factors and in-hospital outcomes of patients done Off pump with those done On pump CABG. Material na Method: One hundred seventy eight patients was underwent CABG between January 2001 and July 2001 12 patients whom underwent associated valvular or left ventricular volume reduction surgery were excluded in this study Data were collected for 52 Off pump CABG and 114 On pump CABG for patient and disease risk factors, extent of coronary disease, and in-hospital outcomes. Result: Off pump CABG and On pump CABG groups did not show any differences in their patient and disease risk factors, and extent of coronary disease. Off pump CABG group had significantly lower mean operation time(234 $\pm$ 37 min vs 290 $\pm$ 48 min, p<0.001), lower mean CK-MB level(10.1 $\pm$ 13.5 IU/L vs 33.1 $\pm$ 18.2 IU/L, p<0.001) and mean ventilation time(14.8 $\pm$ 3.5 hours vs 16.2 $\pm$ 4.9 hours, p=0.048) than On pump CABG groups. On pump CABG group had significantly more distal grafts(3.4 $\pm$ 0.9 vs 2.6 $\pm$ 0.8, p<0.001) than Off pump CABG groups. There were no operative mortality in two groups. Off pump) CABG and On pump CABG groups did not show any differences in their postoperative complications and outcomes including perioperative myocardial infarction, stroke, respiratory failure, renal failure, reoperation, the amount of bleeding, the need of intraaortic balloon pump, the need of inotropics, and the stay of intensive care unit and hospital. Two patients were converted to On pump CABG. Conclusion: This study showed that patients having Off pump CABG are not exposed to a greater risks of adverse outcomes and also provided evidence that patients having Off pump CABG have significantly lower operation time, CK-MB, ventilation time and less distal grafts. Although there may be potential benefits to Off pump CABG, further studies must be directed to determine those patients who would benefit from Off pump CABG.
