PURPOSE: Growth hormone(GH) has not only growth promoting effect but also various metabolic effects. We evaluated GH effects by anthrometric data, biochmical data, electrolytes and simple CT in patients with Prader-Willi syndrome. METHODS: Nine children with Prader-Willi syndrome(PWS) were studied. The children were treated with GH(0.6U/kg/week) for 6 months. Before and after therapy we measured height, weight, waist, hip, and thigh. Blood sampling for eletrolytes, HgA1C, lipid profiles and other biochemistry were done in all patients before and after therapy. We also compared fat distribution with scan. RESULTS: Height standard deviation (SD) score increased from -0.7 to -0.5 and weight SD score decreased from 5.3 to 4.9. Body mass index(BMI) decreased from 28.2kg/m2 to 27.2kg/m2. But the changes in height, weight and BMI were not significant statistically. The waist/hip ratio decreased from 1.04 to 0.97(P<0.05), Thigh circumference had been decreased from 58.2+/-21.7cm to 49.9+/-6.9cm insignificantly. The visceral fat were decreased from 7,613+/-1,760 to 5,022+/-1,533 after GH therapy, and thigh muscle mass was increased from 6,358+/-1,616 to 7,175+/-2,155 (P<0.05). Total cholesterol and triglyceride decreased and HDL cholesterol increased after therapy although they were insignificant statistically. There were no differences in electrolytes, HgA1C, other biochemistry(Ca, P, protein, albumin, BUN, Cr) before and after therapy. CONCLUSION: In children with PWS, waist/hip ratio and fat mass were reduced and muscle mass was increased after GH therapy. There was tendency that total cholesterol and triglyceride decreased and HDL cholesterol increased after therapy. We confirmed that GH therapy had not only growth promoting effect but also metabolic effect on lipid and protein metabolism in children with PWS.

This study was undertaken to observe the mutagenic occurrence in urine excreted after the ingestion of roast beef. Two healthy nonsmoker persons of both sex were selected for this test, employing two strains (TA98, TA100) of Salmonella typhimurium according to Ames' method. The mutagenic activity began to appear in urine of both sex three hours after ingestion of 300 g of roast beef, gradually increasing until 6 hours and declining thereafter.

A case of Dariers disease was presented and the literatures were reviewed. The patient was 20 year old male whose skin lesions revealed normal skin colored, dirty, scaly, keratotic papules with mild itching on face, anterior chest, back, abdomen, axillae, groins and flexural surfaces of extremities. They had a tendency to aggrevate in summer and improve in winter. Histopathologically, suprabasal lacunae, hyperkeratosis, papiIIomatosis, moderate degree of acanthosis and corps ronds in Iacuna were demonstrated in the epidermis. Dermal papillae surrounded with single layer of basal cells proliferated inta the lacunae. Upper dermis revealed mild nonspecific inflammatory cell infiltrates.

PURPOSE: This cross-sectional study was done to compare factors influencing smartphone addiction in middle school boys and girls. METHODS: Participants were 390 middle school students (boys 198, girls 192) who were living in Seoul. Data were analyzed using SPSS 20.0 program. RESULTS: Factors influencing smartphone addiction for boys were stress, the motivation to use smartphone as a tool of ostentation and fashion, depression, self-control, and teacher control over the use of smartphone. Factors influencing smartphone addiction for girls were stress, the motivation to use smartphone as a tool of ostentation and fashion. CONCLUSION: The results suggest that it is necessary to consider gender characteristics in order to develop effective management programs for smartphone addiction in middle school students.

PURPOSE: This study was done to identify the effects of weight-bearing exercise(WBE) on bone metabolism. METHOD: WBE was performed for 12 weeks by healthy college women. Bone-related parameters were measured four times during this period by evaluating the immunoradiometric assay and enzyme immunoassay. Bone mineral densities(BMDs) were measured by dual energy x-ray absorptiometry before and after the WBE program. Data was analyzed using t-test, paired t-test, x2-test, and repeated measures ANOVA. RESULT: Osteocalcin, a bone formation marker, increased more in the experimental group than in the control group based on the interaction between time and group(F=3.29 p=.024). Little difference between the two groups was found for the other parameters: urinary deoxypyridinoline, insulin-like growth factorI, parathormone, serum calcium, and serum phosphorus without showing any time interaction between the groups. The femoral trochanter BMD rose in the experimental group while that of the control group fell, showing a significant difference for BMD(t=3.06 p=.005). However, there was no significant difference between the two groups for changes in BMD of the forearm, lumbar spine, femoral neck, and femoral ward's triangle. CONCLUSION: These findings supported the WBE is beneficial for increasing bone formation in college women and long-term application is needed to substantiate the effects of WBE as a intervention in promotion of bone-health.

Background:Insulin dependent diabetes mellitus(IDDM) is known to be a disease characterized by a deficiency of insulin caused by destruction of the pancreatic beta-cells. It has been suggested that the clinical and immunological characteristics of IDDM in Korean are different from those of Caucasian. This study was undertaken to investigate the clinical characteristics and the prevalence of autoimmune markers in type I diabetic children and their prediabetic siblings in Korea. METHODS:Insulin autoantibody(IAA), antiglutamic acid decarboxylase(Anti-GAD) antibody, thyroid autoantibodies such as antithyroid antibody(ATA) and antimicrosomal antibody(AMA), and rheumatoid facter(RF) in 54 type I diabetic children have been measured. Diabetic autoimmune antibodies were also measured in 48 siblings. RESULTS: 1)Clinical characteristics of type I diabetic children were that age of onset was 8.6+/-4.4 years, duration of diabetes was 4.1+/-3.3 years. C-peptide at onset of diabetes was fasting 0.7+/-0.5ng/ml, and postprandial 1.2+/-0.5ng/ml, and HbA1c was 12.5+/-4.3%. 2)The positivity of IAA and anti-GAD antibody of type I diabetic children was 74% and 50% respectively. ATA and AMA positivity of type I diabetic children was 3.7% and 5.6%. however RF was not detected at all. Among the diabetic siblings, 48 persons for anti-GAD antibody, 21 for IAA, 27 for ICA were measured but 1 case was positive for IAA. 3)Clinical characteristics of type I diabetic children were not specific different between IAA and anti-GAD antibody positivity. But the mean age of onset of type I diabetic children was younger in case of both positivity of IAA and anti-GAD antibody than both negativity(7.8 vs 11.4 years old, P<0.05). 4)A case in whose brothers are diagnosed as IDDM has shown that autoantibody of elder brother was positive in both IAA and anti-GAD antibody, and younger brother was also strongly positive in IAA. Another case in whose sisters were IDDM, has shown that, while elder sister was positive in IAA, younger sister strongly positive in both IAA and anti-GAD antibody. 5)In a case of identical twin brother, the elder is type I diabetic child and the younger is normal, elder brother's onset of age was 6 years and 8 months old, and titer of anti-GAD antibody was measured as strong positive. Both ICA and anti- GAD antibody were negative in normal younger brother. First phase insulin release in IV GTT and the insulin levels in oral GTT showed reduction from the normal level in normal brother, and repeat check up showed normal ranges but on-going study is needed under observation. CONCLUSION: The prevalence of autoantibody positivity of type I diabetic children of Korea in this study were IAA 74%, and anti-GAD antibody 50%. Cases with both IAA and anti-GAD antibody positive were shown to be earlier onset. Though titers of auto-antibody in IDDM twins, brothers and sisters were strongly positive, auto-antibodies in siblings of IDDM patients were detected only one case with IAA positive(0.47%). We suggest that the pathogenesis of IDDM in Korean is different from foreign countries in terms of prevalence of autoimmune antibodies and more numbers of diabetic siblings should be tested for further study.
