The purpose of this study was to observe the effects of the feeding physiological activity substance in feral peach(Prunus Persica Batsch var. davidiana Max.) extract intake on the improvement of the lipid compositions, apolipoprotein and blood pressure level in spontaneously hypertensive rats(SHR, Wistar strain, male) fed the experimental diets for 33 days. Concentrations of total cholesterol, triglyceride(TG), LDL-cholesterol, free cholesterol and atherosclerotic index in serum were significantly lower in the feral peach extract intake groups[groups 5g% Ex.(basal diet+feral peach 5.0g% extract), 10g% Ex.(basal diet+feral peach 10.0g% extract)] than those in the group Control(basal diet+water). In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, feral peach 5.0g%, 10.0g% extract intake groups(group 5g% Ex. and 10g% Ex.) were higher percentage than in the group Control. However, concentrations of total cholesterol and TC in liver and brain were significantly lower in the groups 5g% Ex. and 10g% Ex. than those in the group Control. But the concentrations of apolipoprotein (Apo) A-I and Apo A-II in serum were significantly higher in the feral peach 5.0g% and 10.0g% extract intake groups(5g% Ex. and 10g% Ex.) than in the control group. However, concentrations of Apo C-II, Apo C-III, Apo E and ratio of Apo B to Apo A-I in serum were fairly reduced in the groups 5g% Ex. and 10g% Ex. than in the control group. The levels of systolic and diastolic blood pressure were significantly lower in feral peach 5g% Ex. and 10g% Ex. groups than control group. However, no significance was found in the effect of among the groups(groups 5g% Ex. and 10g% Ex.). From these results, physiological activity substance in feral peach(Prunus persica Batsch var. davidiana Max.) extracts were effective on the improvement of the lipid compositions and cardiovascular heart disease, hypertension in spontaneously hypertensive rats. And particularly, feral peach extracts were more effective as a therapeutic regimen for the control of blood pressure in hypertension.

Arteriovenous fistula Is the most widely used mean of vascular access for long-term hemodialysis in patients with end-stage renal disease. Lymphangioma associated with arteriovenous fistula is very rare, seemed to be developed from Iymphatic fluid accumulation. Lymphangioma is benign neoplasm, arises de hobo or secondary to surge y or irradiation, and affects almost any part of the body served by the Lwphasic system. Treatment of choise for Iymphangioma Is surgical excision. We repo$\ulcorner$t a case of procedure using Gore-Tex graft between left brachial artery and cephalic vein for vascular access of hemodialysis in 59 year old female, with successful surgical removal.

Total anomalous pulmonary venous return is a rare but serious cardiac malformation, accounting for only about 1.5~3% of congenital heart disease. Surgical results have been dramatically improved in the last two decades, largely owing to improved techniques of cardiopulmonary bypass and perloperative management. Seven patients ranging in age from 15 days to 11 years with total anomalous pulmonary venous return underwent repair between 1984 and 1995. The types of anomalous return were supracardiac in 5, and cardiac in 2. There were 5 boys and 2 girls. There were two hospital death, occurred in 15-day-old, and 40-day-old infants with supracardiac type. Follow-up periods have ranged from 3 months to 11 years, and all survivors have remained asymptomatic with normal growth and development.

A 4-year-old intact male Shih Tzu dog (weighing 5 kg), was presented with signs of severe dyspnea, exercise intolerance and cyanosis. Diagnostic studies suggested a reverse patent ductus arteriosus (rPDA) with pneumonia. Despite emergency treatments with oxygen, diuretics, antibiotics and medical therapy for hyperkalemia, the dog died of ventricular fibrillation from hyperkalemia and dehydration. Necropsy revealed the rPDA with a marked descending aortic dilation and abnormally arisen left common carotid artery.

Laryngeal web is formed from various causes, and it is a scar tissue covered with epithelium on both sides. The purpose of the laryngeal web surgery is to cover the vocal cords with healthy epithelium and to achieve the normal or near normal function of respiration and phonation. Until now, a lot of surgical procedures were introduced, but have some merits and disadvantages. Recently authors tried this new surgical technique on 6 patients using the suspension laryngomicroscope under the intubation general anesthesia, which was to suture the upper and lower edges of the severed web. This new approach has several advantages; 1) familiar instruments and visual field 2) no unnecessary surgical trauma beyond the operation field 3) one stage operation 4) shorter operation time 5) no serious complications 6) short hospitalization, etc.

Extrahepatic duct duplication is an extremely rare congenital anomaly. Hilar cholangiocarcinoma with extrahepatic bile duct duplication was reported; however, intraductal papillary neoplasm of the bile duct (IPNB) with extrahepatic bile duct duplication has not been reported to the best of our knowledge. We report a rare case of IPNB with extrahepatic bile duct duplication of a 64-year-old female. The patient underwent extended right hepatectomy, and the results of a subsequence histopathological examination were consistent with an IPNB with extrahepatic bile duct duplication. We report this rare case with radiologic imaging findings and a brief review of the current literature.

Background: Coronary artery fistula is rare congenital anomaly, which account for $0.27\~0.40\%$ of all congenital heart diseases. We report the clinical observations of 45 patients with coronary artery fistula. Material and Method: We reviewed all patients presented with or without symptoms of coronary artery fistula between 1987 and 2004. Age ranged from 1 to 83 years. Twenty-six patients were female. The patients were divided into 2 groups according to the presenting symptoms. Twelve patients were in group A (asymptomatic) and 33 patients in group B (symptomatic). The most common clinical presentation in group B was angina (18) followed by dyspnea (7), atypical chest pain (5), syncope (1), fatigue (1), and palpitation (1). Twenty-five patients were associated with other cardiac diseases, which were atrial septal defect (4), coronary artery occlusive disease (6), hypertension (12), and valvular heart disease (2). Result: Patients were followed-up for a mean period of $64.8\pm62.7$ months. There was no complication related to coronary artery fistula during the follow-up period in both group. There was no mortality related to coronary artery fistula. Conclusion: In symptomatic patients, early surgical treatment is recommended considering the low perioperative morbidity. In asymptomatic patients receiving medical treatment, close follow up may be necessary.

Purpose : To analyze abnormal ventricular activation in childhood congenital heart disease induced by postoperative changes in ventricular volume and pressure and ventricular scar formation using signal-averaged electrocardiography (SAECG). Methods : Fifty-two patients who had undergone open heart surgery (OHS) were enrolled. Patients were divided into the following 3 groups: right ventricular volume overload (atrial septal defect, group1), left ventricular volume overload (ventricular septal defect, group2), and right ventricular pressure overload (tetralogy of Fallot, group 3). The patients were monitored by standard 12-lead ECG and SAECG before and 2 months after the operation. QRS duration, QT and QTc intervals, filtered QRS (f-QRS), high frequency low amplitude potential (HFLA), and root mean square (RMS) voltage in the terminal 40 ms of SAECG were determined. Results : In the preoperative period, group1 showed significant increase in QRS (P=0.011) compared to those of the other 2 groups. In the postoperative period, group3 showed significant increase in the QTc interval (P=0.004) compared to those in the other 2 groups. SAECG parameters showed no significant differences among the groups in the pre- or postoperative period. Of the 52 patients, 12 (23%) in the preoperative period and 21 (40%) in the postoperative period had at least 1 SAECG abnormality. The prevalence of SAECG abnormalities was significantly higher in the postoperative group 2 and group 3 (preoperative: 20% versus postoperative: 28%, P<0.001, preoperative: 14% versus postoperative: 64%, P<0.001, respectively). Conclusion : Abnormal SAECG patterns may be attributed to postoperative scars, OHS itself, and/or ventricular overload.

Cleft lip and/or palate (CLP) is one of the most common congenital craniofacial anomalies and occurs more frequently in Asian people. Dental abnormalities in number, size, shape, and eruption of teeth are frequently associated with CLP. The purposes of this study were to investigate the effects of CLP on number, size, shape and eruption of teeth and to provide basic clinical data for diagnosis and treatment of the CLP patients. With the orthodontic and cleft charts, diagnostic models, orthopantomograms and intraoral x-ray films from 241 CLP patients who visited Dept. of Orthodontics, Seoul National University Dental Hospital, we evaluated the frequency of congenital missing teeth, supernumerary teeth, Impacted teeth, and microdontia. The results were as fellows ; 1. Frequency of congenital missing was relatively high up to $56.8\%$. Congenital missing occurred frequently in the maxillary lateral incisor and the maxillary second premolar. Among the CLP types, frequencies of congenital missing in cleft lip and Palate group and cleft lip and alveolus group were higher than those of cleft lip group and cleft palate group. And bilateral cleft showed higher frequencies than unilateral ones. 2. Supernumerary tooth was shown in $11.2\%$ of CLP patients. It occurred frequently in the area between the maxillary lateral Incisors and the maxillary canine. Among the CLP types, cleft lip group showed relatively most highest frequency. 3. Impaction was shown in $18.3\%$ of CLP patients. It occurred most frequently In the maxillary lateral incisor and the maxillary canine than other teeth. Among the CLP types, cleft lip group and cleft lip and palate group showed most highest frequencies. 4. Microdontia was shown in $15.8\%$ of CLP patients. It occurred the most frequently In the maxillary lateral incisors and maxillary canines. Among the CLP types, cleft lip and alveolus group and cleft lip and palate group showed relatively higher frequencies. There was no microdontia in cleft palate group.

Purpose: To follow up Korean patients with metabolic and endocrine disorders ascertained by Korea Genetics Research Center, and assess the long-term effectiveness of extended newborn screening program in Korea. Methods: From January 2000 to December 2017, tandem mass spectrometry and fluoroimmunoassay were employed in extended newborn screening (NBS). The NBS program obtained dried blood spots from 283,626 babies, 48 hours after birth, and screened for galactosemia, congenital hypothyroidism (CH), congenital adrenal hyperplasia (CAH), and 50 preventable inborn errors of amino acid, fatty acid, and organic acid metabolism. Results: 28 cases of amino acid disorders, 75 cases of organic acid disorders, 27 cases of fatty acid disorders, 51 cases of urea cycle disorders, 127 cases of CH, 14 cases of CAH, and 15 cases of galactosemia were ascertained through NBS and subsequent confirmatory laboratory tests. Patients with amino acid metabolic disorders, galactosemia, CH, or CAH were more likely to have a better long-term outcome if detected early. Early management of MSUD led to much better outcome in over 90%. Despite early intervention, 32% of other organic acidemia cases still resulted in developmental delay and neurological problems. Fatty acid disorders showed varied results; those with EMA and MCAD had a good outcome, but those with VLCAD had serious neurological problems and considerably higher mortality. 75% with UCD experienced serious neurological complications and higher mortality. Conclusion: The nation-wide NBS program must be accompanied by comprehensive long-term management and physician and family education of inborn errors of metabolism for a better outcome.
