Large-scale copy number variants (CNVs) in the human provide the raw material for delineating population differences, as natural selection may have affected at least some of the CNVs thus far discovered. Although the examination of relatively large numbers of specific ethnic groups has recently started in regard to inter-ethnic group differences in CNVs, identifying and understanding particular instances of natural selection have not been performed. The traditional FST measure, obtained from differences in allele frequencies between populations, has been used to identify CNVs loci subject to geographically varying selection. Here, we review advances and the application of multinomial-Dirichlet likelihood methods of inference for identifying genome regions that have been subject to natural selection with the FST estimates. The contents of presentation are not new; however, this review clarifies how the application of the methods to CNV data, which remains largely unexplored, is possible. A hierarchical Bayesian method, which is implemented via Markov Chain Monte Carlo, estimates locus-specific FST and can identify outlying CNVs loci with large values of FST. By applying this Bayesian method to the publicly available CNV data, we identified the CNV loci that show signals of natural selection, which may elucidate the genetic basis of human disease and diversity.

BACKGROUND: In neonatal respiratory distress syndrome patients, various types of pulmonary air leak contributes to elevate morbity and mortality. Although early surgical interventions can provide better results in several cases, whole clinical outcomes are poor. This study was designed to investigate the clinical aspects of pulmonary air leak in the neonatal respiratory distress syndrome patients and major contributing factors to mortality. MATERIAL AND METHOD: We retrospectively evaluated 48 cases of pulmonary air leak in the neonatal respiratory distress syndrome patients from September 1994 to May 1997. RESULT: There were 15 cases of primary and 33 cases of secondary pulmonary air leakages. The prominent manifestations were pure interstitial emphysema in 19 cases(39.9%) and combined pneumothorax in 19 cases(39.9%). In clinical aspects, normal birth weight was dominant(83.4%), the onset occurred within 24 hours was in 28 cases(58.8%). The pulmonary diseases were meconium aspiration syndrome(25.2%) and hyaline membrane disease(33.2%). The overall hospital mortality was 25.2%, and the majority were hyaline membrane diseases. CONCLUSION: Although the overral mortality rate of these diseases were high, more detailed studies about immediate treatement, perinatal prevention, intensive care to geriatric problems were needed individually to improve outcomes.

PURPOSE: Obesity is one of the most frequent markers of health risk and the incidence of obesity has increased in Korea recently. Obesity leads to higher risks of hypertension, hyperlipidemia and insulin resistance. It also leads to risks of respiratory complications. This study was done to view the different effects of obesity on pulmonary functions according to body fat distribution before and after exercise. METHODS: 257 obese children enrolled in this study. All subjects were divided 2 groups, upper body obesity and lower body obesity group according to waist to hip ratio, trunk obesity and extremity obesity group according to centrality index. Pre-and post-exercise loading FEV1, FVC and PEFR were checked in all subjects and the changes of values in each groups were observed. RESULTS: 1) There were 68, 189, 136 and 121 children in upper body obesity group, lower body obesity group, trunk obesity group and extremity group respectively. 2) The % predicted value of FEV1, FVC and PEFR in upper body obesity group were lower than those in lower body obesity group before exercise loading. And the reduction of % predicted values of each parameters was more prominent in upper body obesity group than in lower body obesity group after exercise loading. 3) There was no difference of pulmonary function between trunk and extremity obesity group before exercise, but the reduction of % predicted values of each parameters was more prominent in trunk obesity group than in extremity obesity group after exercise loading. CONCLUSION: The exercise induced bronchospasm is more prominent in upper body and trunk obesity group than in lower body and extremity obesity group. Therefore the fat distribution of obese children must be considered in diagnosis and control of obesity.

Medical record of 66 eyes which had undergone pars plana vitrectomy for the treatment of proliferative diabetic retinopathy were reviewed to study their clinical features, incidences and types of complications, visual outcome, and visual prognostic factors. The final visual outcome showed the improvement in 50[76%] eyes, no change in 13[20%]eyes, and the worsening in 3[4%] eyes. Preoperative prognostic factors favoring final visual acuity included the followings:1]insulin dependent diabetes mellitus which developed before 30 years of age, 2]absence of iris neovascularization, 3]absence of tractional macular detachment. Postoperative complications included vitreous hemorrhage in 34[52%]eyes, cataract in 12[19%]eyes, increased intraocular pressure in 6[10%]eyes, rhegmatogenous retinal detachment in 4[6%]eyes, choroidal effusion in 3[5%]eyes, corneal epithelial defect in 2[3%]eyes, neovascular glaucoma in 1[2%] eye. Postoperative complications associated with poor visual outcome were rhegmatogenous retinal detachment and neovascular glaucoma.Intraoperative complication of iatrogenic retinal tear did not seem to deteriorate the final visual acuity.

The authors examined the induntivity of sister chromatid exchanges (SCE) in peripheral lum-phocytes on the personnel working in the operating room and analyzed the factors associated with it to obtain data for their monitoring health status. The results obtained were as follows; 1) Average inductivity of SCE in peripheral lymphocytes of operating room perssonnel exposed to anesthetic gases was 7.85 per cell; it was significantly higher than in those who were not exposed (p< 0.05). 2) The inductivity of SCE in peripheral lymphocytes by age group and exposure duration was not statically significant (p<0.05). 3) The inductivity of SCE in the subjects with a smoking habit was significantly higher than those without a smoking habit (p<0.05). 4) There was no significant difference in the inductivity of SCE between the subjects with a drinking habit and those without it (p>0.05). 5) It is possible that the high inductivity of SCE in operating room personnel who both with drink and smoke was due to more the influence of their smoking than their drinking.
