A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier

Recently, economical withering and environmental pollutions are appearing in the mine area in Taeba다 뭉 jungsun because over 300 coal mines have been closed. We have to consider the coal mine industries as cultural things and improve them through preservation, proper development, recovery of nature and giving them new functions. Therefore, in this study, I suggest the new coal museum, which is connected to existing coal mine industries architecturally, and make the active space, which is able to solve the problems above. In addition, through harmony of things to preserve, recording of history, education about underground resources and connecting to tourist resort such as casino, the museum take an important role as a cultural space and we can expect new functions and values of closed mine area, which is causing environmental and civil problems.

Purpose : To describe ultrasound(US) and CT findings of primary epiploic appendicitis Materials and Methods : From March, 1999 though Novemer 1999, clinical, US, and CT findings were reviewed in nine patients with primary epiploic appendicitis (eight women and one men, aged 27-54 year[mean, 36 years]). All patients performed US and four patients performed abdominal CT. The main symptoms were rapid onset, localized abdominal pain and tenderness(left lower quagrant pain[n=8], right abdominal pain[n= 1]) Results: US revealed small, ovoid, and mass are echogenic(n=7) or isoechoic(n=2) mass, located anterolateral to the colon. The echopattern of the mass are echogenic(n=7), or isoechoic(n=2). CT performed in four patients shown small oval fatty mass with a thin peripheral rim and central high attenuation area at anterolaeral side of the colon. Some streaky infiltration are associated around the fatty mass. Conclusion: Primary epiploic appendicitis has fairy. characteristic US and CT findings that enable a rapid diagnosis and valuable far differential diagnosit of other condition of acute abdomen.

However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

It is known that mutagenic effects can be related to various serious diseases, including cancer and birth defects. Therefore, detailed attention must be given to methodologies for evaluation of mutagenicity of dental materials, so that safe use of the products is ensured. The aims of this study were investigated the potential mutagenicity of compounds from 9 commercial dentin bonding agents (including primers and adhesives) using the Ames Salmonella typhimurium/microsome assays. Through this tests, Tenure S Bond Enhancer was showed mutagenecity and Tenure and Prima less in Salmonella typhimurium TA100 without metabolic activation. Hipolite Dentine was showed slight and Veridonfil-Photo, Prima and Tokuso Mac-Bond less in Salmonella typhimurium TA100 with metabolic activation. From this study, it was needed to further study with other kind of mutagenic tests.

<P>Tristetraprolin (TTP) and <I>let-7</I> microRNA exhibit suppressive effects on cell growth through down-regulation of oncogenes. Both TTP and <I>let-7</I> are often repressed in human cancers, thereby promoting oncogenesis by derepressing their target genes. However, the precise mechanism of this repression is unknown. We here demonstrate that p53 stimulated by the DNA-damaging agent doxorubicin (DOX) induced the expression of <I>TTP</I> in cancer cells. TTP in turn increased <I>let-7</I> levels through down-regulation of <I>Lin28a</I>. Correspondingly, cancer cells with mutations or inhibition of p53 failed to induce the expression of both <I>TTP</I> and <I>let-7</I> on treatment with DOX. Down-regulation of <I>TTP</I> by small interfering RNAs attenuated the inhibitory effect of DOX on <I>let-7</I> expression and cell growth. Therefore, TTP provides an important link between p53 activation induced by DNA damage and <I>let-7</I> biogenesis. These novel findings provide a mechanism for the widespread decrease in TTP and <I>let-7</I> and chemoresistance observed in human cancers.</P>

This study aimed to present the prognosis after minor acute ischemic stroke (AIS) or transient ischemic attack (TIA), using a definition of subsequent stroke in accordance with recent clinical trials. In total, 9,506 patients with minor AIS (National Institutes of Health Stroke Scale ≤ 5) or high-risk TIA (acute lesions or ≥ 50% cerebral artery steno-occlusion) admitted between November 2010 and October 2013 were included. The primary outcome was the composite of stroke (progression of initial event or a subsequent event) and all-cause mortality. The cumulative incidence of stroke or death was 11.2% at 1 month, 13.3% at 3 months and 16.7% at 1 year. Incidence rate of stroke or death in the first month was 12.5 per 100 person-months: highest in patients with large artery atherosclerosis (17.0). The risk of subsequent events shortly after a minor AIS or high-risk TIA was substantial, particularly in patients with large artery atherosclerosis.

Specialty barley extracts were prepared and investigated for its antioxidant activity and biological activity. Hunter $L^*$ values of the Iksan 86 extracts had higher than that of the Iksan 87 and Zasoojeongchal extracts. The extraction yields of Iksan 86, Iksan 87, and Zasoojeongchal was 8.08, 6.62, and 7.30%, respectively. The contents of total phenolic compounds of the Iksan 86, Iksan 87, and Zasoojeongchal extracts were 16.24, 15.51, and 13.95 GAE mg/g of sample, respectively. The DPPH radical scavenging activity of Iksan 86, Iksan 87, and Zasoojeongchal extracts were 50.00, 33.27, and 7.56% at a 500 ppm, respectively. The samples showed an inhibition of xanthin oxidase. ACE inhibition effect of specialty barley extracts, Iksan 86, Iksan 87, and Zasoojeongchal, was 39.81, 41.06, and 27.78%, respectively. Tyrosinase inhibition rates (%) of Iksan 86, Iksan 87, and Zasoojeongchal extracts were 26.21, 24.57, and 20.00%, respectively. Results indicated that specialty barley extracts possesses various biological activities including antioxidative capacity, xanthin oxidase inhibition activity, angiotensin converting enzyme inhibition activity, and tyrosinase inhibition activity.
