PURPOSE:In infants born intrauterine growth retardation(IUGR), there may be persistent short stature in childhood and adulthood, although most IUGR infants show some degree of catch-up growth. The purpose of this study was to describe the postnatal growth status in order to determine the incidence of catch-up growth. METHODS:This study was carried out with the 260 IUGR infants(birth weight<2,500gm) born at Inje University Sanggye Paik Hospital, from October 1989 to March 1995. RESULTS: 1)Mean gestational age was 38.3+/-.6weeks, mean birth weight was 2.3+/-.2kg and mean birth length was 46.1+/-.7cm. 2)Mean height standard deviation score(height SDS) was 0.02+/-.03. Height SDS was -0.002+/-.71 at 1 year of age, 0.03+/-.14 at 2 years of age, -0.03+/-.71 at 3 years of age, 0.01+/-.24 at 4 years of age, 0.16+/-.24 at 5 years of age, -0.08+/-.43 at 6 years of age. 3)Of the entire study group of the 260 children, 16 children (6%) were below 10 percentile in height. 1 of 36 (2.8%) was below 10 percentile in height at 1 year of age, 5 of 86(5.8%) at 2 years of age, none at 3 years of age, 6 of 44 (13.6%) at 4 years of age, 1 of 25 (4.0%) at 5 years of age, 3 of 17 (17.6%) at 6 years of age. 4)Height SDS significantly correlated with gestational age (r=0.57, p<0.01), birth weight (r=0.17, p<0.01) and midparental height (r=0.72, p<0.01). 5)Birth length and midparental height showed significant differences between catch-up group and non-catch-up group (p<0.01). Condusions:In summary, of the infants born IUGR, 94% showed catch-up growth. Birth length and midparental height were significantly lower in non- catch-up group.

Eleven patients with proved Bronchiolo-aveolar cell carcinoma were found in the chest department of thenational menical center from 1975 to 1981. The incidence of Bronchiolo-alveolar cell carcinoma is recentlyincreased as primary lung carcinoma. The result as follow. 1. The ratio of male and female was 5:6 and anincidence of 4.4% among total primary lung cancer patients. The highest incidence (3 of cases) was seen in thesixth decade, and the remaining cases were evenly distributed in the third, fourth, and fifth decades of life.Among them youngest was 29 years old and the oldest was 66 years old. 2. Clinical and radiological initialdiagnosis prior to the final diagnosis were as follows; pulmonary tuberculosis; 7 cases, pneumonia; 1 case,bronchiectasis; 1 case, and lung cancer; 2 cases. 3. Radiological examination of chest presented several pictures;most commonly, homogenous or patchy infiltrations; 6 cases, nodular or mass like densities; 2 cases, disseminatednodular or military patterns; 2 cases, and reticular pattern; 1 case. 4. Bronchogram reveald no contributablefindings except one case of complete tappering obstruction of the segmental bronchus. Therefore we arrive at theconclusion that early diagnosis will result in increased resectability and improved survival so aggressivediagnositic work-up for suspicious pulmonary infiltrate is necessary.

5.The Clinical Usefulness of the Teller Acuity Cards Test in Preverbal Children.
Journal of the Korean Ophthalmological Society 2005;46(2):330-335
PURPOSE: To determine the clinical usefulness of the Teller Acuity Cards(TAC) test in infants and preverbal children less than 48 months old. METHODS: We retrospectively analyzed 55 consecutive patients. We had measured visual acuity with the TAC test for the preverbal period, and optotype acuity was measured with Hahn's letter chart for the follow-up period. Test-retest long-term repeatability was evaluated by comparing the last two TAC acuities. We compared the last TAC acuity with the first optotype acuity to estimate the predictive validity of the TAC test. Finally, we also tested the reliability of the TAC test compared with the optotype acuity test for the assessment of interocular visual acuity differences in patients with unilateral amblyopia. RESULTS: The mean age of patients at the initial TAC test was 21.6 months. The first optotype acuity was obtained at the age of 37 months. Earlier TAC acuity correlated significantly with later TAC acuity (r=0.77, p<0.001). Although the TAC test underestimated the visual acuity more than the optotype test, there was minimal correlation between the two tests (r=0.28, p<0.05). In the presence of the interocular difference of visual acuity with the TAC test, unilateral amblyopia as assessed by optotype test could be anticipated (r=0.44, p<0.05). CONCLUSIONS: The TAC test can be used as a reliable method to estimate visual acuity in infants and preverbal children. Earlier The TAC acuities are valid predictors of optotype acuities later in childhood. The TAC test is an especially useful method in detecting unilateral amblyopia.

PURPOSE: The aim of this study was to analyze the tasks of managers who were working in the Customized Visiting Health Services (CVHS) and to prioritize analyzed tasks according to performance frequency, perceived importance, and difficulty. METHODS: Job analysis method by Hartley (1999) was used for task analysis and performance frequency, perceived importance, and difficulty were used for prioritize as criteria. A total of 85 managers in the CVHS of public health centers nationwide were recruited through e-mail and mail survey. Using SPSS/WIN 15.0, descriptive statistics, such as frequency distribution, means, median, and standard deviation, were conducted to examine each subject's general characteristics, the frequency, importance, and difficulty of the tasks as well as to prioritize the each task. RESULTS: The job description of the managers revealed 12 duties, 35 tasks, and 104 task elements. Of the 85 managers, 84.8% were classified as nurses, 40.5% were home health care specialists, and 32.9% were social workers. Their coretasks were management of client cases, budget management, and management of work performance and quality assurance. CONCLUSION: Considering the analyzed managers' tasks and core tasks, we need to examine each manager's role precisely and provide various educational programs for improving overall manager competence.

The superoxide anion, hydrogen peroxide, and hydroxyl radical are oxygen free radicals which arise in cell metabolism and which are toxic to cells, with an important role in carcinogenesis. The measurement of the oxygen free radical is a problem due to the instantaneously changing nature, and therefore the superoxide dismutase(SOD) is employed which act as an oxygen free radical scavenger. The authors quantitatively analyzed the SOD levels in normal uterine cervix epithelium, cervical intraepithelial neoplasia, and in invasive cervical cancer patients by the SOD-525R spectrophotometric assay and compared the results between each group with respect to prognostic variables such as stage of disease, cell type, lymph node involvement, and SCC Ag(TA-4 Ag) levels. The mean SOD levels were 0.41U/ml, 0.39U/ml and 0.73U/ml in the normal uterine cervix, intraepithelial neoplasia, and invasive cervical cancer groups, respectively, showing statistically significant difference by the Oneway anova test(p=0.05). The mean SOD levels according to the stage of disease were 0.5U/ml, 0.62U/ml, and 1. 15U/ml for stages I a, I b, and stage II and above(p=0.029). For the cell type the SOD levels were 0.77/ml for squamous cell carcinoma and 0.57U/ml for adenocarcinoma(p=0.15). For cancer cell lymph node involvement cases, the mean SOD levels were 0.75U/ml and 0.57U/ml for lymph node involvement and no involvement respectively(p=NS). The mean SOD levels also did not show any significance when compared with SCC Ag levels where SOD was 0.78U/ml for SCC Ag levels of more than 2.0ng/ml, and 0.77U/ml for SCC Ag levels of less than 2.0ng/ml. From the above results the authors conclude that SOD levels were higher in invasive cervical cancer tissues compared to intraepithelial neoplasia and normal cervical tissues, that SOD levels increased with higher stage of disease, and that there was no relationship between SOD levels and known prognostic variables such as cell type, lymph node involvement and SCC Ag level.

Journal of the Korean Surgical Society 2007;73(5):359-365
PURPOSE: This study examined the effects of Tacrolimus (FK506) on the expression of the apoptotic signal transduction proteins of Jurkat human T-lymphocytes. METHODS: The cell viability was examined by a MTT assay, DAPI stain, enzyme activity of caspase family proteins, and western blotting for Bcl-2, Bak, Fas, and Fas-L. The cells were cultured in the presence or absence of FK506. FK506 induced cell death was confirmed to be apoptosis by the observation of nuclear fragmentation. RESULTS: The viability of Jurkat cells was decreased by the addition of FK506 in a dose- and time- dependent manner. The FK506 induced activation of caspase-3 protease was observed. FK506 didn't increase the catalytic activity of caspase -6, -8, and -9 proteases of Jurkat cells in a time-dependent manner. The viability was improved when a caspase-3 inhibitor was added. However, the caspase-9 inhibitor did not affect the viability. Bak protein expression was increased, and the Bcl-2 protein was decreased for some time. The expression of Fas and Fas-L were unaffected by FK506. CONCLUSION: FK506 induces dose- and time-dependent apoptotic cell death, and enhances the apoptosis of Jurkat cell by increasing the expression of Bak and caspase-3.

Journal of the Korean Pediatric Society 1998;41(7):953-959
PURPOSE: Leptin is a protein encoded by the ob gene that is expressed in adipocytes. It regulates eating behavior by the action to the satiety centers in the hypothalamus. In ob/ob mouse, adipocytes can not produce leptin because of a mutation in the ob gene which results in obesity. Whereas, leptin concentrations were elevated in obese adults, and leptin levels in obese children has not been studied much until now. The purpose of this study is to evaluate leptin concentrations in obese children and to find out correlating factors with leptin. METHODS: Thirty-six obese childrens whose weight is above 97 percentile of korean weight standard and 39 children with average weight were included. Height, weight, waist to hip ratio, fat weight and lean body mass were measured. The serum levels of leptin, insulin, cholesterol and triglyceride were measured. RESULTS: Mean age was 10.8 +/- 2.5 years in obese group and 10.6 +/- 2.6 years in control group. Obesity percent was 51.6 +/- 18.8% in obese and 8.8 +/- 10.2% in control group. Body mass index (BMI) was 26.3 +/- 5.8kg/m2 in obese group and 17.3 +/- 1.9kg/m2 in control group. Leptin levels of obese group (13.7 +/- 5.4ng/ml) were significantly higher than that of the control group (3.6 +/- 3.3ng/ ml). Leptin levels showed no significant difference by gender and by pubertal development. Leptin levels significantly correlated with BMI, obesity percent, fat weight, and serum cholesterol level but showed no significant correlation with lean body mass, serum fasting insulin and triglyceride levels. CONCLUSION: Serum leptin levels of obesity group were significantly higher than that of the control group, and they were correlated with BMI, obesity percent and fat weight. Additional research is necessary to assess the mechanism of leptin resistance in obese children.
