Peptic disorders are among the most common maladies in korea as the world. In most cases their etiologies not be established and their pathophysioolgy remain obscure. Although the persence of fastric bacteria has been logn established, recently campylobacter pylori seems to be etiologic agent of peptic disorders. Campylobacter pylori is visualized in most cases of peptic disorders and not visualized after treatment of bctericidal agents, bismuth compound or metronidazole. We had a following results for identification of campylocacter pylori in stomach and duodenal mcuosa via endoscipc biopsy. 1. We studied 54 patients who had dyspeptic symptoms, 29 males. 2. Most patients are in 5th decades, next in 3rd and 6th in order. 3. Ptients were composed of 27 peptic ulcer, 22 gastitis and 5 gastric carcinoma. 4. Campylobacter pylori was identified in 69% of total patients, peptic ulcer 63%, gastritis 77%, stomach carcinoma leastly.

Objective : We analyzed and investigated clinical manifestations, laboratory tests, and inhibitor development of hemophilia that had not been thoroughly studied. Methods : We retrospectively reviewed 96 patients with hemophilia who were registered in the Hanyang University hospital from Jan, 1984 to Dec, 2003, Results : The total patients, whose median age at onset was 46.0 months, in clude 84 cases of type A (87.5%) and 12 cases of type B (12.5%). The most common chief complaint was a traumatic hemorrhage. The family histories of hemophilia were revealed in 41 cases (42.7%). The median activated partial thromboplastin time (aPTT) was 66.7 seconds. The number of severe cases was 39 (40.6%). Inhibitors were present in 13 cases (13.5%) and seven cases (53.8%) were high responders. aPTT and factor levels showed reverse correlation (r=-0.467). aPTT is more prolonged in group without family history than the group with family history (P=0.037). Conclusion : In this study, the diagnosis of hemophilia are made at the lower age and the serological positivity of the HCV is decreased. Activated partial thromboplastin time and factor levels shows reverse correlation. Activated partial thromboplastin time is more prolonged in group without family history compared with group with family history. The frequencies of family history are lower than those of other developed countries, because of concealing the family history of hemophilia. The prevalence of the development of inhibitors increased compared with those of previous studies in Korea, but was lower than those of other countries. Further studies would be necessary to decrease the inhibitor development.

A new process on the preparation of porous nickel by electroless plating was developed using fine graphite powders of 1㎛-2㎛ particle diameter and polyurethane foam. In this process, graphite powders were introduced into the pores(foams) existing within polyurethane foam in order to supply electric conducting seeds for nickel deposition by electroless plating reaction. After the electroless plating, remaining polyurethane was removed chemically using organic solvent and most of graphite powder seeds also removed by ultrasonic cleaning. Porous nickel plates with 250㎛-300㎛ thickness and porosity comparable to commercial sintered nickel plate were obtained and found out that the platesare of mono-layer structure composed of spherical nickel particles connected each other in two-dimensional scale.

We consider a facility layout problem for optimized material flow system design in the automated production system design. Existing facility layout algorithm have a weak point that arranged facilities have irregular shape or don't preserve their own shape and size. The proposed algorithm give a layout which is minimize total material handling cost and maximize space utility under preserving each facilities own shape and size.

Background Treatment protocols for light chain (AL) amyloidosis have been derived from myeloma treatment. Bortezomib is a key drug used for the treatment of myeloma and AL amyloidosis. We retrospectively investigated the efficacy and toxicity of bortezomib- based chemotherapy in patients with newly diagnosed AL amyloidosis. Methods We reviewed the outcomes of newly diagnosed autologous stem cell transplantation (auto-SCT)-ineligible AL amyloidosis patients who received bortezomib-based chemotherapy at a referral center between 2011 and 2017. Results Of 63 patients who received bortezomib-based chemotherapy, 32 were male, and the median age was 66 years (range, 42‒82 yr). The hematologic overall response rate (ORR) was 65.1%, and the chemotherapy regimen with the best hematologic response was VMP (75.7%, 28/37). Sixty patients had significant organ (heart or kidney) involvement; 28.3% of patients (N=17) had major organ responses after chemotherapy. With a median follow- up of 34 months, there was no significant difference in progression-free survival (P=0.49) or overall survival (P =0.67) according to regimen. Most hematologic and non-hematologic problems were manageable. Conclusion Various chemotherapy combinations based on bortezomib are currently employed in the clinical setting, but no difference was found in terms of efficacy or toxicity.

We investigated the effects of fadrozol, an aromatase inhibitor (AI), and $17{\alpha}$-methyltestosterone (MT) on the induction of sex change in juvenile longtooth grouper $Epinephelus$ $bruneus$, via histological observation of gonads. Changes in the mRNA expression of GtH subunits (FSH-${\beta}$ and LH-${\beta}$) in the pituitary, and estradiol-$17{\beta}$ (E2) and 11-ketotestosterone (11-KT) levels in the blood were also surveyed after AI and MT treatment. Juvenile longtooth groupers ($113{\pm}17g\;body\;weight$; $16.2{\pm}1.2cm\;body\;length$) received intramuscular injections of AI at 3 (3-AI) and 5 (5-AI) mg/kg BWdoses and MT at a 5 mg/kg BW (5-MT) dose. At week 7 post-injection, 3-AI and 5-MT oocytes were degenerated, and gonads of the 5-AI group initiated spermatogenesis. At week 21 post-injection, 3-AI- and 5-MT-treated gonads contained spermatogonia and spermatocytes, while 5-AI treatment induced advanced stages of spermatogenesis. The serum E2 level showed no significant differences throughout the experimental period, whereas that of 11-KT was significantly elevated in the 5-AI group at weeks 7 and 21 post-injection. A significant increase in the expression of FSH-${\beta}$ mRNA was evident in the 5-AI group at week 21 post-injection. In contrast, LH-${\beta}$ mRNA expression did not significantly differ among groups during the experimental period. These results imply that sex change has two stages in the longtooth grouper. In the first stage, oocytes are degenerated by the stimulation by 11-KT, and in the second stage spermatogenesis occurs, owing to the co-effects of 11-KT and FSH-${\beta}$.

Background/Aims: Data regarding the outcomes of primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in nonagenarians are very limited. The aim of the present study was to evaluate the temporal trends and in-hospital outcomes of primary PCI in nonagenarian STEMI patients. Methods: We retrospectively reviewed data from the Korea Acute Myocardial Infarction Registry (KAMIR) from November 2005 to January 2008, and from the Korea Working Group on Myocardial Infarction (KorMI) from February 2008 to May 2010. Results: During this period, the proportion of nonagenarians among STEMI patients more than doubled (0.59% in KAMIR vs. 1.35% in KorMI), and the rate of use of primary PCI also increased (from 62.5% in KAMIR to 81.0% in KorMI). We identified 84 eligible study patients for which the overall in-hospital mortality rate was 21.4% (25.0% in KAMIR vs. 20.3% in KorMI, p = 0.919). Multivariate analysis identified two independent predictors of in-hospital mortality, namely a final Thrombolysis in Myocardial Infarction (TIMI) flow < 3 (odds ratio [OR], 13.7; 95% confidence interval [CI], 3.2 to 59.0; p < 0.001) and cardiogenic shock during hospitalization (OR, 6.7; 95% CI, 1.5 to 30.3; p = 0.013). Conclusions: The number of nonagenarian STEMI patients who have undergone primary PCI has increased. Although a final TIMI flow < 3 and cardiogenic shock are independent predictors of in-hospital mortality, primary PCI can be performed with a high success rate and an acceptable in-hospital mortality rate.
