  • Body fat distribution in patients with Prader-Willi syndrome (PWS) is characterized by reduce lean body mass (LBM), increased total body fat mass (FM), and lower percentage of visceral adipose tissue (VAT). Individuals with PWS seem to have a lower risk for insulin resistance with high levels of adiponectin, an anti-atherogenic adipocytokine that is decreased in visceral fat hypertrophy subjects compared to simple obese subjects, both in children and in adults. The mechanism of the reduction in visceral adiposity in PWS is still unclear. It might be related to qualitative intrinsic characteristics of adipocyte or novel genetic influences on the control of fat distribution. However, obesity remains a critical problem, and obesity status plays a crucial role in individual metabolic risk clustering and development of metabolic syndrome (Mets) in PWS children and adults. Long-term growth hormone (GH) treatment after cessation of skeletal growth improved body composition, with an increase in lean body mass and a reduction in total body fat and subcutaneous and visceral fat in PWS adults. Thus, the role of GH is important after childhood because it might attenuate obesity and Mets in PWS adult by adipocyte modification.

  • Objectives To investigate the relationship between Heart Rate Variability and menopause among obese middle-aged women in Korea. Subjects and Methods Forty middle-aged women (age 49.05 $\pm$ 2.64 years) with BMI > $23kg/m^2$ were recruited by local advertisement. Blood profiles of estrogen, FSH, LH, glucose, total cholesterol, HDL-cholesterol, and triglyceride were measured. Autonomic Nervous System (ANS) was estimated by short-term spectral analysis of heart rate variability (HRV). Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were accessed using Computerized Tomography (CT), Bioimpedance Analysis (BIA), and anthropometry. To scrutinize the influence of ANS on obesity-related factors, we divided the subjects into pre- and post-menopausal women. Results The total cholesterol, FSH and LH were significantly higher in post-menopausal obese women group. The estradiol and standard deviation of all normal R-R intervals (SDNN), high-frequency components (HF) of the HRV were significantly lower in postmenopausal obese women group (P<0.05). Adipose tissue distribution and blood profiles were not significantly different between two groups. Conclusion Menopause induced a decrease in SDNN and HF values and increase in total cholesterol level in obese women although the VAT itself was not related with ANS in obese women.

  • Persistent organochlorine pesticides and polychlorinated biphenyls (PCBs) have been used intensively in agriculture or industry for a long time. The occurrence of organochlorine pesticides and PCBs in the environment and subsequently in parts of the food chain, resulting in the intake of these compounds by man and animal. The measure of the levels of organochlorine pesticides and PCBs in tissues or blood of human populations are good markers in determining the extent of exposure and in the evaluating the hazards. So, most countriess have conducted initial monitoring programs to determine organochlorine pesticides and PCBs in human tissues. But a few report has been presented in Korea. In this study, $\alpha$-BHC, $\beta$-BHC, ${\gamma}$-BHC, $\delta$-BHC, p,p'-DDT, p,p'-DDD, p,p'-DDE, endrin, dieldein, aldrin and 7 marker PCBs (28, 52, 101, 118, 138, 153, 180) were determined in human blood, adipose tissue and liver tissues collected at autopsy of 10 men and 10 women, 13-79 year of age. Significant differences in the levels of organochlorine pesticides and PCBs between districts where they had lived were found in the following chemicals: total PCB in the blood : $\beta$-BHC, total BHC, p,p'-DDE and total DDT in the adipose tissue : p,p'-DDE, total DDT and PCB 118 in the liver. No significant difference was found in the levels of organochlorine pesticides and PCBs between sexes and ages. Though the levels of organochlorine pesticides and PCBs were relatively lower than that of other countries, we could know that organochlorine pesticides and PCBs have been widely distributed in Korean human body.

  • In order to investigate the residual amounts of organochlorines and polychlorinated biphenyls (PCBs) in Korean human tissues (blood, adipose tissue, liver, kidney cortex, and lung), the samples were collected from the autopsied cadavers of 40 men and 40 women (from teens to seventies of age). ${\alpha}-BHC,\;{\beta}-BHC,\;{\gamma}-BHC,\;{\delta}-BHC$, p,p'-DDT, p,p'-DDD, p,p'-DDE, endrin, dieldein, aldrin, and 7 marker PCBs (28, 52, 101, 118, 138, 153, and 180) were determined in human tissues. The levels of organochlorines and PCB congeners indicated that they have been widely distributed in Korean human body. Positive correlations in terms of age were observed for the following cases: p,p'-DDE, p,p'-DDT, ${\Sigma}-DDT$, PCB 118, PCB 138, PCB 153, and ${\Sigma}-PCB$ in the adipose tissue, and p,p'-DDE in the lung. Concentration of these compounds showed a significant age-related increase. Accumulation of these compounds in aged people revealed that these compounds were more slowly eliminated in our environment and risk assessment was necessary for further proper action. Significant differences in the levels of PCBs between genders were found for PCB 118 in the adipose tissue and PCB 138 in the liver. Positive correlation coefficients between tissues were detected with p,p'-DDE and ${\beta}-BHC$.

  • In order to investigate the effect of dietary fatty acids on lipids metabolism in adipose pads and superficial pectoral muscle of chicks, the present, experiment was carried out using signle comb White Leghorn male chicks fed a fat-free diet and diets containing margaric, stearic or linoleic acids. Total lipids of tissues were extracted with a chlorofrom-methanol solution. The lipid components were fractionated by thin layer chromatography and the fatty acid distribution of lipid fractions was determined by gas liquid chromatography. The neck adipose pads contained 34-62% total lipids, in which triglycerides, were dominant, being 97-98%. Margaric, stearic and linoleic acids were distributed at a relatively high rate in the adipose tissue when the corresponding acids were fed, and margaric acid feeding lowered palmitoleic acid distribution and linoleic acid feeding elevated stearic acid distribution. The wet superficial pectoral muscle contained 1.3-1.7% total lipids, of which 77-79% was phospholipids and 11-13% was free cholesterol. When margaric acid was fed, margaric and heptadecenoic acids appeared in the muscle lipids. When linoleic acid was fed, this acid was significantly highly distributed in every muscle lipid fractions, whereas, when stearic acid fed no elevation of stearic acid distribution was observed. In the muscle phospholipids, oleic acid was significantly highly distributed in the stearic acid fed chicks, and the linoleic acid feeding signigicantly lowered the distribution value of palmitic and oleic acids, but elevated the distribution value of stearic acid. And the linoleic acid feeding lowered the distribution value of eicosatrienoic acid and elevated the distribution value of arachidonic acid.

  • Background Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face. Methods Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini-approaches to ensure adequate distribution. Results Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients' parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients' facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance. Conclusions We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto-orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients' self-esteem starting at an early age.

  • Purpose: Visceral adipose tissue may be strongly linked to increased metabolic risks in adults. However, because little is known regarding the effect of visceral adipose tissue in children and adolescents, we performed this study to determine the association between abdominal fat distribution and metabolic risk factors in this population. Methods: One hundred one children and adolescents (78 males and 23 females; mean age, 10.8${\pm}$2.4 years) were enrolled. The anthropometric data and metabolic risk factors were evaluated. Theabdominal fat distribution was assessed according to the CT measurement. Age-adjusted, partial correlations were performed among the visceral adipose fat area (VFA), subcutaneous adiposefat area (SFA), metabolic risk factors, and anthropometrics. Results: The SFA increased more rapidly than the VFA with advancing years in both genders. In males, the VFA and SFA were positively correlated with anthropometrics. The VFA was correlated with low HDL-cholesterol and the SFA was correlated with diastolic blood pressure (DBP). However, there was no statistical significance between the VFA, SFA, anthropometrics, and other metabolic risk factors. The VFA and SFA were strongly linked to a number of metabolic risk factors, such as other anthropometrics. Conclusion: This study investigated how a low HDL-C was correlated with VFA and how a high DBP was associated with SFA in Korean male children and adolescents. Our results suggest that the correlation between the VFA, SFA, and metabolic risk factors was relatively weak compared to that reported in previous adult studies.

  • CCAAT/enhancer binding proteins(C/EBP) are a group of transcription factors expressed during preadipocyte differentiation. In the C/EBPs, C/EBPa plays an important role in lipid deposition and adipocyte differentiation. In this studies, we report the identification, characterization, and expression of a Hanwoo CIEBP$\alpha$ The Hanwoo C/EBP$\alpha$DNA includes a 1059 bp open reading frame encoding a protein of 353 amino acids. The CIEBPa amino acid sequences of the Hanwoo show strong conservation with the corresponding sequences reported in other species. The distribution of C/EBP$\alpha$ mRNA in various tissues of Hanwoo aged 12 months were investigated using Northern blotting analysis. The highest expression was detected in adipose tissue and more lower expression was detected in colon and lung. We also identified expression of C/EBPa mRNA in Hanwoo sirloin and adipose tissue aged 12, 26, and 30 months by real-time RT-PCR. The higest expression were detected at 26 months in the sirloin and at 12 and 26 months in the adipose tissue.

  • Objective : The aim of the study was to investigate the effect of Acanthopanax senticocus(AS) herbal acupuncture on the metabolic syndrome in high-fat diet fed mice. Methods : ICR mice were fed with high-fat diet to induce the metabolic syndrome. During the inducement of the metabolic syndrome, the groups were treated with AS herbal acupuncture with different concentrations(125mg/kg, 250mg/kg and 500mg/kg) to the point of Sinsu(BL23) everyday for 5 weeks. Thereafter, body weight, feed efficiency ratio, blood pressure, blood glucose, insulin level, insulin resistance, oral glucose tolerance test(OGTT), lipid profile(TG, TC, HDL-C, LDL-C, NEFA), mass of liver, histology of white adipose tissue(WAT) and brown adipose tissue(BAT), and expression of GLUT-4 and UCP-1 mRNA were measured. Results : The risk factors of metabolic syndrome such as obesity, non-insulin dependent diabetes mellitus(NIDDM), insulin resistance, hypertension, dyslipidemia were aggravated by high-fat diet for 5-weeks. AS herbal acupuncture inhibited the development of weight gain, hyperglycemia, hyperinsulinemia, insulin resistance, hypertension, dylipidemia and expression of GLUT-4 in WAT and UCP-1 mRNA in BAT, and also improved oral glucose intolerance and distribution of adipose tissue.

  • The effect on body fat accumulation on male Wistar rats undergoing continuous feeding with a histidine-enriched diet was investigated. Five-week-age rats were assigned to two groups and were fed either the control diet (purified diet AIN-$76^{TM}$) or the histidine-enriched diet containing 3% histidine for 28 days. It was observed that both adipose tissue masses in retroperitoneal and epididymal areas of rats fed histidine-enriched diet significantly decreased (p<0.05) compared to those of control rats, while there was no significant difference in the food efficiency ratio between them. The blood levels of histidine derivatives of 3-methylhistidine and carnosine were significantly (p<0.05) increased in the rats fed a histidine-enriched diet, whereas there were no significant different between the histidine-enriched diet and control groups in the general amino acid distribution. Our results demonstrate that a histidine-enriched diet suppresses body fat accumulation in rats.
