To estimate the prevalence and trend of obesity in primary school-age children, obesity survey was performend in children aged 6 to 12 years(5,226 boys and 5,048 girls)in Kwangju in 1991. Obesity was defined as overweight if more than 20 per cent above the median weight for height and age(relative weight>120%). The following results were obtained: 1) The prevalence of obesity that exceeded the weight centiles at each height by more than 97th percentile was 8.78. Boys (9.70%)was not significantly higher than in girls(7.82%)(p>0.05). 2) The prevalence of obesity that exceeded the standard weight for height by more than 20% was 8.82%. Among them, 5.45% were mild obesity and 2.93% were moderate obesity and 0.44% were severe obesity. The prevalence rate of obesity was no significant differences by sex(p>0.05). 3) Regionally, the prevalence of obesity was a lower rate in Kwangiu in 1991 (8.82%)than that in Seoul in 1989(11.68%).

Hospitals have been very susceptable to changes in external environment. Accordingly, they have been experiencing great financial difficulty due to low insurance rates and increasing competition. As a remedy, hospitals have attempted to use computer in a strategic manner. Such system is called strategic information system (SIS) , and order communication system (OCS) is an example of SIS in hospital setting. While OCS has known to be effective in reducing waiting time for outpatients, many hospitals are reluctant to introduce this system mainly because there are no real data or methods for justifying the cost of the system. Cost-benefit analysis has been traditionally used for such purpose, but this method deals with limited portion of benefits and therefore not very useful for analyzing the economic feasibility of SIS. In this paper, information economics tools which expand cost with value was used to analyze the economic feasibility of OCS. To assist the analysis, financial simulation model was developed using simulation package, called IFPS (Interactive Financial Planning System).

Superoxide dismutase(SOD), catalase and glutathione peroxidase and the levels of lipid peroxide were assayed in erythrocytes and synovial fluid isolated from 17 patients with osteoarthritis of the knee joints and 7 with healthy knee joints as a control groups. In the erythrocytes, SOD, catalase and glutathione peroxidase activities were significantly increased in osteoarthritis compared with normal control groups, but the changes of malonyldialdehyde level was not significant. The activity of SOD in synovial fluid was significantly decreased in osteoarthritis compared with normal control groups, but catalase activity was significantly increased in synovial fluid of osteoarthritis. This result suggested that the increament of antioxidant enzymes in erythrocytes were probably due to increased production of oxygen radicals in osteoarthritis. In osteoarthritis, knee joints might be injured more easily by oxygen radicals because of decreased activity of SOD in synovial fluid of osteoarthritis.

BACKGROUND: Psoriasis is a chronic relapsing disease characterized by epidermal hyperproliferation and epiderrnal and dermal inflammatory cell infiltration. The etiology of this disease is still unclear. Recently, there has been growing interest in the probable role of a T cell mediated immune response in the pathogetiesis of psoriasis. The infiltrating cells in psoriatic lesions have been iden- tified by monoclonal ant~ibodies and T cells were found to be the major infiltrating type. OBJECTIVE: This stud was done to investigate the difference of cellular infiltration and adhesion molecule exg!ressions between early and late skin lesions of psoriasis using immunohistochernical studies. Methpds : Patients with psoriatic lesions were divided into two groups. The early gr oup were defined as having skin lisions that had lasted for about 4 weeks, and late group were defined as having skin lesions that had lasted for more than 8 weeks. Then biopsy specirnens were stained using monoclonal antibidies for CD4, CD8, CD1, LFA-1, and ICAM l. RESULTS: 1. CD4 positive cells,vere tly increased in both the early and late groups compared with CD8 positive cells. Z. CD8 positive cells were significantly increased in the late g~roup compared with the early group. 3. CDl-posit,ive dendri!ic cells were more nurnerous in the late group than the early group. 4. There were no significant differences between the early and late group with regard to numbers of LFA-1 positive (ells. 5. ICAM-1 were more strongly expressed on epidermal keratinocytes in the late than the early group. CONCLUSION: CD4-positive cells are important in early and late psoriatic lesions and CD8 positive cells playi more important role in late than early lesions. ICAM-1 and LI'A-1 play a role in cell adhesion of infiltrating cells and lymphocytic rnigration to the epidermis.

PURPOSE: Palmitic acid in infant formulas has been shown to lower calcium and fat absorption because of its structural difference from human milk. Some studies reported the inclusion of palm and palm olein oil in infant formula led to lower bone mineralization. We aimed to determine whether the sn-2 position palmitic acid fortified infant formula influences growth and skeletal development, by comparing bone mineral accretion and bone markers in formula-fed infants to those in breast-fed ones. METHODS: We determined anthropometrics and feeding intake in three groups of full term newborn infants fed different diets at 6 and 12 weeks after birth; Group A (n=15) was fed human milk, Group B (n=15) was fed formula alpha (31% sn-2 palmitic acid as a mainly plant source), Group C (n=15) was fed formula beta (31% sn-2 palmitic acid as a mainly animal source). Total body bone mineral content (BMC) and bone mineral density (BMD) were measured at 12 weeks of age using dual energy X-ray absorptiometry. We measured bone-specific alkaline phosphatase (B-ALP), C-terminal propeptide of type 1 collagen (CICP) as markers for bone formation, and deoxypyridinoline crosslinks (total DPD) as a marker for bone resorption at 6 and 12 weeks. RESULTS: There were no significant differences between feeding groups in body weight, height, head circumference, and skinfold thickness at 6 and 12 weeks. The concentrations of B-ALP, CICP, and total DPD were not significantly different between feeding groups at 6 weeks. The concentrations of B-ALP and total DPD were not significantly different between feeding groups at 12 weeks. The concentrations of CICP in Group B and C were higher than that of Group A (P<0.05). BMC and BMD in formula-fed infants (Group B and C) were not different from those of breast-fed ones (Group A). BMC and BMD in Group B were higher than that of Group C (P<0.05). CONCLUSION: The growth and bone mineralization in infants fed sn-2 position palmitic acid fortified formula were not different in those of breast-fed ones.

Authors experienced an unusual case of malunited trans-epiphyseal fracture of the proximal femur in a 2 year-old girl. She was treated at a private clinic by closed reduction and cast immobilization, which subsequently resulted in malunion and capital subluxation. Because of subsequent failure of remodelling of the subluxated malunited fracture for two years, corrective femoral varisation and internal rotation osteotomy was done to reduce the subluxated femoral head. Postoperatively congrous reduction was obtained and gradual remodelling of the malunited fracture took place during 5 and a half years follow-up period.
