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.

In order to examine the neurotoxic mechanism of oxygen radicals on cultured bovine oligodendrocytes, cytoxic effect of oxygen radicals was examined when cultures were treated with various concentrations of xanthine oxidase (XO) and hypoxanthine (HX) in culture medium. In addition, the neuroprotective effect of iron-chelators against the neurotoxicity induced by oxygen radicals was evaluated by MTT assay. Cell viability was remarkably decreased in a time-dependent manner after exposure of cultured bovine oligodendrocytes to 20mU/ml XO and 0.1mM HX for 4 hours. In the neuroprotective effect of iron-chelators on oxidant-induced neurotoxicity, tetrakis (2-pyridylmethyl)ethylenediamine (TPEN) blocked the neurotoxicity induced by oxygen radicals, while DFX was not effective in blocking oxidant-induced neurotoxicity in these cultures. These results suggest that oxygen radicals are toxic in cultured bovine oligodendrocytes, and also selective iron-chelators such as TPEN are effective in blocking the neurotoxicity induced by oxygen radicals.

In addition to mutations and copy number alterations, gene fusions are commonly identified in cancers. In thyroid cancer, fusions of important cancer-related genes have been commonly reported; however, extant panels do not cover all clinically important gene fusions. In this study, we aimed to develop a custom RNA-based sequencing panel to identify the key fusions in thyroid cancer. Our ThyChase panel was designed to detect 87 types of gene fusion. As quality control of RNA sequencing, five housekeeping genes were included in this panel. When we applied this panel for the analysis of fusions containing reference RNA (HD796), three expected fusions (EML4-ALK, CCDC6-RET, and TPM3-NTRK1) were successfully identified. We confirmed the fusion breakpoint sequences of the three fusions from HD796 by Sanger sequencing. Regarding the limit of detection, this panel could detect the target fusions from a tumor sample containing a 1% fusion-positive tumor cellular fraction. Taken together, our ThyChase panel would be useful to identify gene fusions in the clinical field.

Nitric oxide (NO) elevates intracellular calcium. But the actions of calcium in NO-induced cell death are not well understood. This study was carried out to investigate the signal transduction pathways of calcium and NO-induced cytotoxicity in H9c2 cardiac myoblasts by using NO donor compounds such as sodium nitroprusside (SNP) and S-nitroso-N-acetylpenicillamine (SNAP). Pretreatment of intracellular calcium chelating agent (BAPTA/AM) or L-type calcium channel blockers (nicardipine, nifedipine, diltiazem and veraparmil) or T-type calcium channel blocker (flunarizine) blocked SNP-induced cytotoxicity respectively only in a three hours. However, thapsigargin (TG), which inhibits endoplasmic reticulum dependent Ca(2+)-ATPase and thereby increases cytosolic Ca(2+), augmented SNP-induced cytotoxicity. The protective effect of BAPTA/AM was inhibited by treatment of protein synthesis inhibitor, cyclohexamide. In addition, pyrrolidine dithiocarbamate (PDTC), NF-kB inhibitor, attenuates the protective effect of BAPTA/AM against SNP-induced cytotoxicity. It is indicated that the protective effect of BAPTA/AM against NO-induced cytotoxicity might be due to the expression of protein related to activation of NFkB. From these results, it is concluded that SNP-induced cytotoxicity is mediated by calcium in a 3 hours via down regulation of protein expression rleated to activation of NFkB.

OBJECTIVES: Intrauterine growth restriction(IUGR) accounts for significantiy increased perinatal mortality and neonatal morbidity rates. The Purpose of this study is to investigate the association between some of the risk factors and the incidence of fetal growth restriction. PATIENTS AND METHOD: The retrospective survey of obstetric records of 2188 mothers, who delivered between July, 1995 and June, 1998, was carried out in Hanyang University Kuri Hospital, with the following inclusion criteria: Korean, singleton pregnancy with live birth and a gestational age of more than 32 weeks. RESULTS AND CONCLUSION: 1) The incidence rate for IUGR was 4,7% during the period of 1995 through 1998. 2) 41.2% of IUGR was due to unknown causes, 58.8% of IUGR was due to known. Among known causes the maternal factor was 40.2%, the placenta factor was 14.7%, and the fetal anomaly was 4%. 3) Among maternal factors, pregnancy induced hypertension was the most common cause. 4) The incidence of IUGR was higher in primiparous women and in female babies. 5) The IUGR group showed lower Apgar scores at 1 and 5 minutes than control group,

PURPOSE: As the influence of mass media increases, the general standard of attractiveness or beauty of a face also changes. The primary purpose of the study is to find out the factors of the attractive and beautiful face recognized by public. METHODS: We picked out standard model photography and operated with Adobe(R) Photoshop(R) and Monariza(R) virtual plastic surgery program. The contour of face, eye, nose, forehead, zygoma, chin and proportion of upper, middle, lower face were changed. The interview survey was conducted through structured standard photo for 310 respondents. That was utilized in the final analysis. Multiple regression analysis was executed by SPSS 12.0. It was used to deal with statistical data and all the other necessary analysis. RESULTS: According to general characteristics of the respondents, many differences were found in preferred face and facial aesthetic subunits. The younger generation preferred the lozenge and inverted triangle shape contour. The respondents over 40 of age preferred the egg shape contour. In chin and zygoma contour, the respondents at the age of 20 preferred distinctly small chin and relatively small lower face. On the other hand, the respondents over 40 of age preferred the wide zygoma relatively. In the proportion of upper, middle, lower face, 51.0% of respondents answered 1:1:1. If they want to have an aesthetic operation, they preferred protruding forehead. Also they preferred the small chin and V-shaped chin in frontal view. CONCLUSION: Many respondents preferred to have a plastic surgery for the better facial subunit. The statistical evidence from this study suggests that the harmony and balance of facial aesthetic subunits make attractive and beautiful face.

Ankylosing spondylitis (AS) is a chronic autoinflammatory disease that affects the spine and sacroiliac joints. Regarding its etiology, although HLA-B27 is known to be the strongest genetic factor of AS, much evidence suggests the potential contribution of non-MHC genes to the susceptibility to AS. Most of these non-MHC genes have been discovered in non-Asian populations; however, just some of them have been validated in Koreans. In this study, we aimed to identify additional AS-associated single-nucleotide polymorphism (SNP) candidates by replicating the candidate SNPs in Korean AS patients and healthy controls. For this, we selected three SNPs (rs11249215 in RUNX3, rs6556416 in IL12B, and rs8070463 in TBKBP1), which were previously reported as risk factors of AS but have not been studied in Koreans, and performed genotyping assays using a total of 1138 Korean samples (572 AS patients and 566 healthy controls). Of the three SNP candidates, one SNP in RUNX3 (rs11249215) was significantly associated with the risk of AS (odds ratio, 1.31; 95% confidence interval, 1.02 to 1.68, p = 0.03). These results will be helpful in elucidating the pathogenesis of AS and may be useful for developing AS risk prediction models in Koreans.
