It is obvious that adequate nutrition is essential for growth and development of school children, and many elementary schools in this country have already practiced it. Therefore, it would seem apparent that the school feeding program would have a significant effect on the growth and development of school children. This paper presents a two-year experimental school-feeding program from 1973 to 1974, and attempts to evaluate its effects by before-and-after nutrition surveys conducted in two elementary schools, one experimental and the other as a control. The two schools are both located in the same county (Yongin-Kun, Kyunggi-Do), and the families of their students are presumed to share the same socio-economic level. To assess the effect of school-feeding, we measured height, weight, chest circumference and grasping power. Physical examination was done foresigns of nutritional deficiency. A stool examination for parasites and blood examinations for hemoglobin, hematocrit and serum protein were included. Analysis were done for 150 students selected randomly at the beginning of the program. These students attended the school throughout the program period. Results are as follows: 1. The amount of increase of height, weight, chest circumference and grasping power were greater in the experimental school than in the control school, but the differences are not statistically significant. 2. Signs of vitamin deficiency decreased in both experimental and control schools during the two-year program period. 3. At the time of the 1974 post-survey, values of Hb. & Hct. revealed no significant differences between the two schools, but serum protein level was a little higher than that of general Korean rural children of the same age. 4. Infestation rate of parasites had increased in both schools during the two-year program period. 5. Each student of the two schools was classified into three major classes, according to the level of economic condition of his or her parents, namely higher, middle and lower. The results of each class of the experimental school was compared with that of the corresponding class of the control school, expecting the relative magnitude of change largest in the lower economic class of the experimental school. However, change was greatest in the middle class, still not being statistically significant. Finally, the authors concluded that the two-year period for such a program is not sufficiently long for its beneficial effects to be demonstrated and measured. As long as the growth and development of children are concerned, planning with a more distant perspective is required, as well as the development of new methods of evaluation.

Typical urodynamic findings in patients with intracranial lesion are uninhibited bladder contraction (detrusor hyperreflexia) with coordinated sphincter activity. However, the findings of urodynamic study are variable and dependent on the degree and site of intracranial lesion, the presence of underlying disease and the adequacy of initial management of voiding problems from onset of the neurologic symptoms. . In this study, we tried to investigate the urodynamic findings in 40 patients who had intracranial lesions (traumatic or organic brain disease) with voiding dysfunction. The following results were obtained. 1. Out of all 40 patients, 35 had organic brain disease such as infarct, intracranial hemorrhage, or Parkinsonism etc. and 5 had traumatic brain disease. 2. Among 40 patients, detrusor hyperreflexia was presented in 29 (72.5%), detrusor areflexia in 9 (22.5%) and normal detrusor pressure in 2 (5%). 3. In 29 cases of detrusor hyperreflexia, there was no history of urinary retention, but in 12 cases with history of urinary retention, 9 cases (75%) revealed as detrusor areflexia. 4. No specific cause except the history of urinary retention was considerable in 8 of 9 patients with detrusor areflexia. In our study, urodynamic findings in the patients with intracranial lesion who had voiding dysfunction revealed nine cases (22.5%) of detrusor areflexia and the presumptive cause of detrusor areflexia is considered to previous urinary retention. Therefore, highly individualized and programmed early urologic involvement on the basis of urodynamic study is recommended for the prevention of urinary retention in initial ""cerebral shock"" stage of cerebrovascular accident and when detrusor areflexia had been developed, intensive management for the removal of the residual urine is necessary.

PURPOSE: The purpose is to aid in the diagnosis and obstetric management by analysing the ultrasonographic findings of prenatally diagnosed Edward syndrome. METHOD: The study population consisted of 15 cases prenatally diagnosed Edward syndrome from January 1993 to January 1999. The medical charts and ultrasonographic findings were reviewed retrospectively, and especially the ultrasonographic findings before prenatal genetic diagnosis were anlyzed. RESULTS: All of the 15 cases reviewed showed at least one ultrasonographic finding suggesting Edward syndrome. In the first trimester, 2 cases revealed cystic hygroma and increased nuchal translucency, and after the second trimester, major structural anomalies including congenital heart anomalies and minor ultrasonographic findings such as choroid plexus cyst were noted. All of cases after 21 weeks of gestation showed congenital heart anomaly, and as the pregnancy progressed there was an increased tendency of intrauterine growth restriction and polyhydramnios. CONCLUSION: Prenatal ultrasonography in the screening process of Edward syndrome can be placed as a very informative method, as all of the Edward syndrome cases revealed at least one abnormal ultrasonographic findings. As congenital heart anomalies were found in all of the cases after 21 weeks of gestation, fetal echocardiography should be considered in evaluating suspected cases of Edward syndrome.

A total of 120 infants, children, and teenagers, who were admitted to the Department of Pediatrics, Severance Hospital from April 1989 to August 1989, were examined by cross-sectional echocardiography. Right and left atrial and ventricular dimensions and areas were measured in the parasternal, apical, and subcostal views. Dimensions of the inferior caval vein, the pulmonary and the aorta were obtained in the parasternal, suprasternal, and subcostal views. The results were as follows : 1) Statistical analysis showed no difference between boys and girls. 2) For all parameters, a positive linear correlation was found with age, height, weight, and body surface area. The best correlation was with body surface area. 3) The correlation was further improved if the logarithmic values of the measurements and body surface area were considered. 4) Measurements by cross-sectional echocardiography are clinically useful, especially in the study of the right-sided cardiac structures that are difficult to evaluate with M-mode echocardiography, but the problems of reproducibility have to be taken into account.

PURPOSE: Congenital hypothyroidism(CH) is not uncommon disorder, leading to retardation of mental development and growth, if not treated early. The aim of this study is to determine the factors influencing IQ of children with CH, diagnosed after 1 month of life. METHODS : Thirteen children with CH were included. They had intelligence test by KEDI-WISC(Korean Educational Development Institute-Wechsler Intelligence Scale for Children) and their medical records were reviewed. Their T4, TSH, height, age at diagnosis were investigated retrospectively. To evaluate the influence of T4, TSH, height, age at diagnosis on IQ, children were divided into three groups ; athyroid(n=8), sublingual(n=3), inborn errors of thyroid hormone synthesis(n=2) according to the result of thyroid scan. Results : In athyroid group, IQ closely correlated to VIQ and PIQ and had close relationship to T4 at diagnosis(.p=0.0086, r=0.8427), but no relation to TSH. There was no difference in height, T4 TSH, and IQ between athyroid and sublingual group. CONCLUSION : The results suggest that intellectual function in children with CH, diagnosed after 1 month of life depends on serum level of T4 at diagnosis. Further study is mandatory to elucidate the relationship between final IQ and factors, including thyroid function, age at diagnosis, adequacy of treatment, etc.

BACKGROUND: Although the pathophysiology of pulmonary vascular injury has been reported, exact its mechanism has not yet been elucidated. Recent studies have reported that reactive oxygen species, including hydrogen peroxide(H2O2) and superoxide, formed in association with a variety of oxidative stress-related diseases, may play an important role in cell injury and apoptosis. In this study, we investigated whether H2O2 induces apoptosis, a possible mechanism of pulmonary vascular injury. MATERIAL AND METHOD: The calf pulmonary artery endothelial cell line(CPAE) was used in the experiment. For the measurement of cytotoxicity of H2O2, 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide(MTT) assay was performed. To find out whether H2O2 affects cell morphology, cells were examined by phase-contrast microscopy. To confirm the induction of apoptosis, H2O2-treated cells were analyzed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL) assay, 4',6-diamidino-2-phenylindole(DAPI) staining and flow cytometric analysis. RESULT: Compared to the untreated control(100%), viabilities of cells treated with H2O2 of concentrations of 10 microM, 50 microM, 100 microM and 500 microM for 3 hours were about 70%, 33%, 26% and 28%, respectively. Morphologically, H2O2-treated cells(50 microM) showed retraction of processes, cell shrinkage, cytoplasm condensation and irregularity of shape. Both TUNEL assay and DAPI staining also showed typical apoptotic features of nuclear condensation and nuclear fragmentation in some nuclei of H2O2-treated cells. Through flow cytometric analysis, it was determined that there was an increased number of cells in the sub-G1 phase and a decreased number of cells in the G1 phase among the H2O2-treated cells, compared to those of the control. CONCLUSION: Through morphological and biochemical analyses, it was first demonstrated that cell death induced by H2O2 in CPAE showed classic apoptotic features. These results suggest the possibility that H2O2-induced apoptosis may, in part, be involved in the molecular mechanism of pulmonary vascular injury.

OBJECTIVE: Traumatic brain injury is related to the acute stress response, and this can be accompanied by an elevated serum glucose level. So we estimated the influence of hyperglycemia on neurologic, functional status and outcome. METHOD: We studied the 139 traumatic brain injured patients who had been admitted to the department of neurosurgery from 1996 to 2000, retrospectively. We reviewed initial serum glucose level, postoperative glucose level, and Glasgow Coma Scale (GCS), Glasgow Outcome Scale (GOS). We compared these values with functional independence measure (FIM) scores. Patients were divided into two groups according to the initial serum glucose level, then we analyzed the correlation between glucose level and GCS, GOS, FIM. RESULTS: The correlations of early hyperglycemia with GCS, GOS, initial FIM scores were significant (p<0.01). But serum glucose levels were not correlated with plateau FIM scores (p>0.05). Patients with unfavorable neurologic outcome after 10 days from head injury had significantly high serum initial and postoperative glucose levels than those with favorable neurologic outcome (p<0.01). CONCLUSION: In patients who had received rehabilitation therapy with moderate or severe head injury, early hyperglycemia were significantly correlated with initial FIM scores, GCS, GOS, but not with the plateau FIM scores.
