Pelvic inflammatory disease (PID) is a disease that affects young, sexually active, reproductive age women. Most pathogens are Chlamydia trachomatis and Neisseria Gonorrheae transmitted sexually. One of serious acute complication of PID is tubo-ovarian abscess (TOA) that involves the fallopian tube, ovary and adjacent structures (eg, bowel, pelvic peritoneum). The microbiology of TOAs is polymicrobial with anaerobic organisms and causal organisms of PID. Common anaerobic organisms are Peptostretococcus spp, Bacteriodes spp, Prevotella spp, Escherichia coli and aerobic streptococci. Treatment is necessary to admission for intravenous broad-spectrum antibiotics and surgery is often reserved for patients with suspected rupture or patients who fail to respond to antibiotics. So, we reported this case found pelvic abscess due to ruptured tube-ovarian abscess.

There are two perspectives about the affecting of capital structure of the value of the firm. One is irrelevancy theorem, the other is optimal capital structure theory. In irrlevancy theorem, capital structure has no effect on the value of the firm. In optimal capital structure, however, the value of the firm depends on the capital structure. In general, it is accepted that the latter is more valid under more realistic assumptions about the existence of bankruptcy costs and agency costs due to uncertainty in capital market. If optimal capital structure of individual firm exists, firms in the same industry have the same capital structure. If it is true, each industry has different capital structure by examing inter-industry differences in capital structure. For this purpose, cross-sectional analysis and time series analysis are used. The hypotheses tested in this study can be summarized as follows: <hypothesis> 1. H∧O : Firms in different industries have the same capital structure. H∧A : Firms in different industries have systematically different capital structure. 2. H∧O : The relative rankings of mean industry capital structure across time are random. H∧A : The relative rankings of mean industry capital structures across time are stable. 3. H∧O : The movement of a firm's leverage with respect to the industry mean is random. H∧A : The leverage of firms within an industry tends to converge to the mean industry leverage. For analysis, this thesis examined the capital structure of 9 industries covering 118 firms from1980 to 1987. For each industry in a given research term, the ratio of debt in the capital structure was calculated. Statistical tests methods, One-Way Analysis of Variance, Correlation Analysis, and Fisher Exact Probability test, is employed. We draw three major conclusions from these test results. First, capital structure of different industries in korea is highly significant at least between two industries, but pairwise tests which analyze the differences among various industries represent that differences between two industries is not statistically significant. Second, to analysis that the relative rankings of mean industry of capital structures across time are stable, correlation analysis is employed. As a result, the relative rankings of capital structures across time are not stable. For the third of this study, Fisher Exact Probability test is employed. The results show that the movement of capital structure of firms within an industry with respect to the industry mean is random

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.

Endothelin(ET) is a 21-residue peptide originally isolated from the cultured porcine endothelial cells. There are at least three genes for endothelin:endothelin-1(ET-1), endothelin-2(ET-2), and endothelin-3(ET-3). Endothelins are present in various human biological fluids including plasma, urine, breast milk, and saliva and have been found elevated plasma ET concentrations in patients with diabetes mellitus, Patients undergoing maintenance hemodialysis due to chronic renal failure, patients with acute myocardial infarction, and patients with subarachnoid hemorrhage. Endothelial cell damage is suspected to occur in diabetic patients and may be one important cause of angiopathy, a major complication in diabetes mellitus. The elevation of ET in diabetic patients may be a marker of, and further exacerbate, their vascular disease. We measured the levels of ET-1 in plasma of 50 patients with non-insulin dependent diabetes mellitus(NIDDM) and 25 normal subjects by radioimmunoassay. The plasma ET-1 concentration (mean±S.D.) in NIDDM was 6.461 A2.510 f㏖/ ㎖, and was significantly higher than in normal subjects (4.567±1.155f㏖/㎖) (P<0.05). The plasma ET-1 concentration (mean±S.D.) in diabetic retinopathy group( 7.15±2.454 f㏖/ml) was significantly elevated than those in otherwise uncomplicated groups (5.348±2.390 f㏖/㎖)(P<0.01). The correlation between any clinical parameters and plasma ET-1 levels in NIDDM was not significant, In conclusion, this study suggest that the elevated levels of ET-1 in diabetic patients may be play a important role in the pathogenesis of diabetic complications.

The nasopalatine duct cyst is the most common non-odontogenic cyst in the oral area and is thought to be originated from the epithelial remnants of the nasopalatine duct. The nasopalatine duct cyst have been mentioned to be an overall incidence of 1.7-11.9% of all jaw cyst. More males than females are affected by that. It could occur all around the age, and especially in their 40th and 60th it happens the most and in childhood it is very rare. Proper treatment for nasopalatine duct cyst is enucleation. In the case of very large cysts, it is likely to be a risk of naso-oral or antral-oral fistulas or of devitalization of teeth, marsupialization is indicated. The purpose of case report is that a nasopalatine duct cyst in is very rare in childhood. A 9-year-old boy was referred to the chosun university pedodontics clinic that this child who has anterior palatal swelling is in routine check. The size of the cyst was so big that the marsupialization was committed and obturator was put. This patient is on the continuous observation. we treated the nasopalatine duct cyst with obturator.

본 논문에서는 주파수 선택성 레일리 페이딩 환경에서 RS부호화, 컨벌루션 부호화, 연접부화를 이용하는 직교 멀티캐리어 BDPSK시스템과 QDPSK시스템의 오율특성을 구하였다. 오율특성은 정규화된 지연시간(??), 비트에너지 대 잡음전력 스펙트럼 밀도비(??), 희망 신호전력 대 지연되 비희망 신호전력비(D/U)를 파라미터로 하여 나타내었다. 검토한 결과, BDPSK 신호인 경우 D/U가 20[dB]일 대 오율을 ??으로 유지하기 위해 필요한 Eb/No는 Rs부호화, 컨벌루션 부호화 및 연접부호화에서느 각각 대략 20.8[dB], 16.0[dB], 14.5 [dB]가 필요하며, QDPSK신호인 경우 Rs부호화, 컨벌루션 부호화 및 연접부호화에서 각각 대략 24.0[dB], 18.9[dB], 13.5[dB]가 필요함을 알 수 있었다. This paper has evaluated the error performance of orthogonal multicarrier BDPSK and QDPSK systems which use Reed Solomon coding, convolutional coding, and concatenated coding technique in a frequency selective Rayleigh fading environment. The results show that when D/U (desired wave's power to undesired delayed wave's power ratio)=20dB at error rate of ??, Reed Solomeon coded BDPSK signal, convolutional coded BDPSK signal, and concatenated coded BDPSK signal need about 20.8[dB], 16.0[dB], 14.5[dB] respectively in terms of Eb/No, and Reed Solomon coded QDPSK signal, convolutional coded QDPSK signal, and concatenated coded QDPSK signal need about 24.0[dB], 18.9[dB], 13.5[dB] respectively.

마우스 EAE, GVHD 질환에서 CTLA4Ig 융합단백의 면역치료 효과

장성옥,홍수종,조훈식,정용훈,Jang, Seong-Ok,Hong, Soo-Jong,Cho, Hoon-Sik,Chung, Yong-Hoon 대한면역학회 2003 Immune Network Vol.3 No.4

Background: CTLA4 (CD152), which is expressed on the surface of T cells following activation, has a much higher affinity for B7 molecules comparing to CD28, and is a negative regulator of T cell activation. In contrast to stimulating and agonistic capabilities of monoclonal antibodies specific to CTLA-4, CTLA4Ig fusion protein appears to act as CD28 antagonist and inhibits in vitro and in vivo T cell priming in variety of immunological conditions. We've set out to confirm whether inhibition of the CD28-B7 costimulatory response using a soluble form of human CTLA4Ig fusion protein would lead to persistent inhibition of alloreactive T cell activation. Methods: We have used CHO-$dhfr^-$ cell-line to produce CTLA4Ig fusion protein. After serum free culture of transfected cell line we purified this recombinant molecule by using protein A column. To confirm characterization of fusion protein, we carried out a series of Western blot, SDS-PAGE and silver staining analyses. We have also investigated the efficacy of CTLA4Ig in vitro such as mixed lymphocyte reaction (MLR) & cytotoxic T lymphocyte (CTL) response and in vivo such as experimental autoimmune encephalomyelitis (EAE), graft versus host disease (GVHD) and skin-graft whether this fusion protein could inhibit alloreactive T cell activation and lead to immunosuppression of activated T cell. Results: In vitro assay, CTLA4Ig fusion protein inhibited immune response in T cell-specific manner: 1) Human CTLA4Ig inhibited allogeneic stimulation in murine MLR; 2) CTLA4Ig prevented the specific killing activity of CTL. In vivo assay, human CTLA4Ig revealed the capacities to induce alloantigen-specific hyporesponsiveness in mouse model: 1) GVHD was efficiently blocked by dose-dependent manner; 2) Clinical score of EAE was significantly decreased compared to nomal control; 3) The time of skin-graft rejection was not different between CTLA4Ig treated and control group. Conclusion: Human CTLA4Ig suppress the T cell-mediated immune response and efficiently inhibit the EAE, GVHD in mouse model. The mechanism of T cell suppression by human CTLA4Ig fusion protein may be originated from the suppression of activity of cytotoxic T cell. Human CTLA4Ig could not suppress the rejection in mouse skin-graft, this finding suggests that other mechanism except the suppression of cytotoxic T cell may exist on the suppression of graft rejection.
