1.Neuropsychological Evaluation of Visual Perception and Construction.
Journal of the Korean Society of Biological Psychiatry 1997;4(1):24-28
Visual perception is a complex process engaging many different aspects of brain functioning. Like other cognitive functions, the extensive cortical distribution and complexity of visual perceptional activities make them highly vulnerable to brain injury. Dectection and characterization of perceptual require careful assessment as well as the application of selected neuropsychological tests. In the article we reviewed neuropsychological assessment of visual perception and constructional abilities. And the principal visuospatial disorders are discussed, the associated neuropsychiatric disorders are presented.

A clincal study was made on 383 adult patients with congenital heart disease who visited the Seoul National university Hospital during the period of March, 1961-July, 1979. 1. The incidence of congenital heart disease for the consecutive years was increasing in 1970s, especially in recent two years. 2. The sex incidence of congental heart disease was female 47.0%, male 53.0%, with male preponderance in tetralogy of Fallot, ventricular septal defect, coarctation of aorta, aortopulmonary window and female preponderance in atrial septal defect, patent ductus arteriosus. 3. Age distribution of congenital heart disease showed that 79.1% of all were below 30 years of age but atrial septal defect showed wide distribution below and above 30 years of age. 4. The incidences of each congenital heart disease were atrial septal defect 20.9%, tetralogy of Fallot 20.6%, ventricular septal defect 19.%, patent ductus arteriosus 12.0%, pulmonary stenosis 7.6%, trilogy of Fallot 1.8%, Ebstein's anomaly 1.8%, ventricular septal defect with pulmonary stenosis 1.3%, coarctation of aorta 1.3%, ventricular septal defect with aortic insufficiency 1.0%, transposition of great vessels 1.0%, in order and rare and various combined anomalies. 5. Average duration of illness in congenital heart disease was less than 15 years in majority, but duration from 11 years to 20 years was most common in tetralogy of Fallot. 6. Functional class of congenital heart disease is class II and I in majority, but class III was most common in tetralogy of Fallot. 7. Comparision of precatheterization diagnosis with postcatheterization diagnosis showed concordence in 92.2% and comparison of postcatheterization diagnosis with postoperative diagnosis showed concordence in 95.5% of cases. 8. Electrocardiographic findings in 5 major congenital heart disease were observed as follows; right ventricular hypertrophy 86.3%, right atrial enlargement 16.4% in tetralogy of Fallot, right ventricular hypertrophy 30.9%, incomplete right bundle branch block 27.9% in atrial septal defect, left ventricular hypertrophy 28.8%, right ventricular hypertrophy 10.6%, biventricular hypertrophy 10.6% in ventricular septal defect, left ventricular hypertrophy 63.2% in patent ductus arteriosus and right ventricular hypertrophy 70% in pulmonary stenosis. 9. Postoperative changes in electrocardiographic findings were observed in 36.1% of operated patients, of whom teteralogy of Fallot 61.7%, ventricular septal defect 48.0% were most common. Pstoperative electrocardiographic changes were complete right bundle branch block 58.3%, incomplete right bundle branch block 11.7%, myocardial ischemia 10%, nonspecific ST-T changes 10%, etc. in order.

Korean Circulation Journal 1995;25(2):499-509
BACKGROUND: Angiotensin convertiong enzyme inhibitors have been shown to exert favorable effects on the left ventricular remodeling process associated with ventricular dilation after coronary occlusion. However, the effects of such therapy on global and regional left ventricular remodeling after coronart artery reperfusion have not been characterized, nor have such effects been assessed after exercise training. METHODS AND RESULTS: Female Sprague-Dawley rats(n=80) were randodmized into 4 groups at 5 days after 45 minutes of left coronary artery occlusion followed by reperfusion. Animals completion the experiment included : Untreated Sedentary group(n=20), Untreated with Swimming Exercise group(n=21), Captopril Treated Sedentary group(n=18) and Captoril Treated with Exercise group(n=21). At 3 weeks after randomization, global and regional morphologic changes of the left ventricle(LV) were examined from mid-ventricular transverse slices which were perfusion-fixed at a constant aortic pressure of 60mmHg and a left ventricular cavity pressure of 10mmHG. At rest and during exercise, compared to untreated rats, the captopril treated animals showed significantly decreased LV weight/tibial length ratio(LV/TL)(p<0.01),increased LV cavity area and dimension(both p<0.01), decreased total myocardial area and noninfarcted area(both p<30.001) and reduced wall thicknesses in the noninfarcted and infarcted regions(both p<0.001). Compared to treated and untreated dsedentary rats, exercise significantly increased LV/TL(p<0.05) and epicardial and endocardial areas in the infarcted zone(both p<0.05) and decreased transmurality(p<0.01). Exercise decreased LV cavity area in the captopril treated groups(42.3+/-10.4 vs. 40.4+/-6.0mm2),whereas exercise increased LV cavity area in the untreated groups(33.5+/-8.9 vs. 39.1+/-6.2mm2)(p<0.05). CONCLUSION: These findings provide evidence in rats for evidence in rats for exaggerated left ventricular dilation and supperssion of compensatory myocardial hypertrophy globally and in the infarct zone with 3 weeks of captopril treatment following coronary artery reperfusion with acute nontransmural myocardial infarction. In addition, the effects of captopril on LV dilation and suppression of global and regional hypertrophic response were partially reversible by swimming exercise.

9.Serum Leptin Levels during Growth Hormone Treatment in Children with Growth Hormone Deficiency.
Journal of Korean Society of Endocrinology 2000;15(4-5):493-501
BACKGROUND: Leptin the ob gene product is secreted by adipocytes and binds to specific receptors in the central nervous system regulating energe intake and expenditure. Correlation between fat mass and leptin level is well established. However, data on the hormonal regulation of the leptin in human are scarce. Growth hormone (GH) has lypolytic action and patients with growth hormone deficiency (GHD) have showed higher leptin levels than expected for the obesity We investigated the changes in serum leptin levels and body mass index in children with GHD during GH therapy. METHODS: Thirty children with GHD participated. All subjects were 5~13 years old and in prepubertal stage. The causes of GHD were idiopathic in 15 and organic in 15 children. Patients received GH 0.6.7 IU/kg/week subcutaneously, in 67 divided doses and investigated at baseline and after 6 and 12 months of GH treatment. Serum leptin levels were determined with a human leptin and IGF-1 radioimmunoassay (Linco Research and Nichols Institute, USA). RESULTS: The height velocity was increased significantly after 12 months of GH treatment. Serum leptin concentrations were significantly reduced after 6 and 12 months of treatment but revealed no significant differences in the sex and the causes of GHD. Body mass indices were significantly reduced after treatment. Serum leptin levels positively correlated with body mass index at baseline and after 6 and 12 months of GH treatment. The serum IGF-1 level were increased significantly after GH treatment and did not significantly correlated with leptin levels at baseline and after treatment. CONCLUSION: This study demonstrated that serum leptin and body mass index were decreased with significant positive correlation during GH treatment in children with GHD.

Journal of the Korean Neurological Association 1988;6(1):110-115
A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.
