In recent study, exercise hypertension is associated with a lower adjusted mortality rate and is likely to a good prognostic sign, although its clinical significance is uncertain. The purpose of this investigation was to study exercise hypertensive reaction and to search its related factors. From June. 1st to Aug. 31st 1996, 108 males, mean age 41.5years(range, 20~70) attended the exercise stress test as volunteers during checking-up of health & disease at Health Service Center of Kwang-ju Christian hospital. The exercise stress test using stationary leg bicycle was done until the examiner were exhausted, at which we measured peak exercise systolic blood pressure & Pulse rate. The results are shown as follows. Exercise hypertension was present in 22 subjects(20.0% ). Including age, body mass index, RPE scales at 70% maximal heart rate, rate of level of elevation of heart rate during exercise, no significant related factors associated with exercise hypertension was present by the discriminant analysis. Multivariate regression analysis demonstrated that exercise-induced increase in systolic blood pressure was positively correlated with only resting systolic pressure(r=0.101, p less than 0.01). RPE(Rating of Perceived Exertion) scales was 18.05+/-1.31 when pulse rate of the examiner was reached to 70% of rnaximal heart rate(220-age (years) ). In conclusion, no significant related factor associated with exercise hypertension was presents, but exercise-induced increase of systolic blood pressure was positively correlated with only resting systolic pressure.

We have discovered copy number variations (CNVs) in 3,578 Korean individuals with the Affymetrix Genome-Wide SNP array 5.0, and 4,003 copy number variation regions (CNVRs) were defined in a previous study. To explore the details of the variants easily in related studies, we built a database, cataloging the CNVs and related information. This system helps researchers browsing these variants with gene and structure variant annotations. Users can easily find specific regions with search options and verify them from system-integrated genome browsers with annotations.

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.

Recently, the detection of traumatic intracerebral hematoma has been greatly expedited by the advent of computed tomography. However, Traumatic Basal Ganglia Hematoma(TBGH) has remained rare and its prognosis has been regarded as poor. The authors obtained following results from the analysis of clinical features and outcome on 50 cases of TBGH who has been treated at the department of neurosurgery, Wonju Christian Hospital from January, 1984 to June, 1988. 1) The incidence of TBGH was 2% of all head-injured patients. 2) The average age of patient was 26.6 years, and the most common cause was motorvehicular accident(80%). 3) The clinical features revealed mental deterioration on 44 cases, followed by motor weakness(23 cases), and decerebrate rigidity(16 cases). 4) The frequent location of hematoma was putamen(27 cases, >50%), internal capsule(9 cases, 14%). 5) The combined lesion showed mostly lower GCS(Glasgow Coma Scale) than solitary lesion(P<0.001). 6) The groups of both GCS above 8(P<0.001) and small hematoma volume below < 15ml(P<0.001) showed relatively good outcome.

Some cases of renal malignancy associated with adult (autosomal dominant) polycystic kidney disease have been reported. Most of these malignancies were diagnosed as renal cell carcinoma. But the case of transitional cell carcinoma has not been reported. We report a case of renal pelvic and urethral transitional cell carcinoma associated with adult polycystic kidney.

To discover genetic markers for autism spectrum disorder (ASD), we previously applied genome-wide BAC array comparative genomic hybridization (array-CGH) to 28 autistic patients and 62 normal controls in Korean population, and identified that chromosomal losses on 8p23.1 and on 17p11.2 are significantly associated with autism. In this study, we developed an 8.5K ASD-specific BAC array covering 27 previously reported ASD-associated CNV loci including ours and examined whether the associations would be replicated in 8 ASD patient cell lines of four different ethnic groups and 10 Korean normal controls. As a result, a CNV-loss on 8p23.1 was found to be significantly more frequent in patients regardless of ethnicity (p<0.0001). This CNV region contains two coding genes, DEFA1 and DEFA3, which are members of DEFENSIN gene family. Two other CNVs on 17p11.2 and Xp22.31 were also distributed differently between ASDs and controls, but not significant (p=0.069 and 0.092, respectively). All the other loci did not show significant association. When these evidences are considered, the association between ASD and CNV of DEFENSIN gene seems worthy of further exploration to elucidate the pathogenesis of ASD. Validation studies with a larger sample size will be required to verify its biological implication.

A 62-year-old diabetic female was admitted to the hospital with fever and pain in both legs. Computed tomography scans of the abdomen revealed necrotizing fasciitis of the right thigh extending into the abdominal wall, and abscesses on the right psoas muscle. Magnetic resonance imaging showed increased T2 signal intensity along the peroneus muscle and fascia of the lower left leg. The patient received antibiotics and underwent debridement of the infected and necrotic tissue. Intra-abdominal abscesses were drained. Blood and pus cultures showed growth of Klebsiella pneumoniae, as had been suspected due to string test results showing hypermucoviscosity. Free-skin grafts were performed to repair tissue loss and the patient was subsequently discharged 82 days after admission. This represents the first reported case of necrotizing fasciitis and psoas muscle abscess caused by a hypervirulent strain of K. pneumoniae in Korea.

Recently, invasive infections with the human pathogen Streptococcus dysgalactiae subspeciesequisimilis (SDSE) have increased around the globe. Typing of the emm gene of SDSE, which encodes a virulence factor (M protein), has provided important information. Here, we report two cases of invasive SDSE infection that presented with endocarditis and bacteremia, and their emm gene types.
