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.

The major characteristics of the developed corn hybrids were compared at each different planting time; 1st time(April 28) and 2nd time(August 20), respectively. Among traits surveyed, stem height showed highly at 1st time than 2nd, while ear height, stem diameter and ear length were similar at two times. Sugar content of the used hybrids showed highly at 2nd planting time than 1st. Pericarp thickness was also high at 2nd planting time. Especially, among hybrids CNU99 was the highest in stem height and ear length, CNU11 and CNU56 were high in sugar content, and CNU51 and CNU124 were thiner than other hybrids in pericarp thickness. Accordingly, these hybrids will be planted and recognized in 2nd yield trial for superior corn hybrid selection.
광선각화증, 각화극세포종과 Bowen's병에서 p53과 p21의 표출 양상
조명구,조현득,양승하,김의한 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.2
Background The function of the p53 protein was known to regulate cell proliferation by inhibiting cells entering Sphase. So DNA damaged cell proliferation was inhibited by apoptosis. P21 is a cyclin dependent kinase inhibitor induced by wild type p53, not mutant p53. Thus p21 is thought go mediate the signal of p53 induced by DNA damaged agents to arrest the cell cycle in G1 phase. p53 and p21 were expressed in many malignant tumors, and its role in oncogenesis, tumor progression and prognosis were important. The authors analyzed immunohistochemical expression of mutant p53 and p21 protein in some skin tumors. Method Thirteen cases of actinic keratosis, 7 cases of keratoacanthoma and 8 cases of Bowen's disease were immunohistochemically stained with p53 and p21 monoclonal antibodies. Results; 1. In cases of positive p53 protein and negative p21 protein, the expressed p53 protein was suggested as mutant form. 2. Positive expression of p53 protein and p21 protein in prickle cell layer of actinic keratosis and Bowen's disease was suggesded that the composing cells of prickle cell layer were transformed into the proliferated cell. The p21 protein expression was suggested to be induced by the p53 independent pathway. 3. Negative expression of p53 protein and p21 protein in prickle cell layer of keratoacanthoma was suggested that the composing cells of prickle cell layer were completely mature cells, so the keratoacanthoma had good prognosis.
일방향응고 초내열합금 CM186LC의 크리프 및 저주기피로 균열생성

The second generation DS alloy CM186LC has comparable creep-rupture life to first generation single crystal alloys CMSX-2 and CMSX-3 in the as-cast and double aged condition. In the assembly of nozzle guide vanes, Ds components are joined into pairs by brazing. In order to study mechanical behavior of the material at the same condition as production, DS bars were subjected to brazing simulated treatments. Compared with standard treatment a small drop in creep-rupture life was observed but the degree of fall in life was not serious. Creep cracks initiated at the transverse components of the grain boundaries, which were normal to the applied stress direction. Every crack was associated with the v-v' eutectic phase at grain boundaries v-v' eutectic was not only located at grain boundaries but also in the interdendritic regions. It also acted as crack initiation site during creep. Low cycle fatigue tests were conducted under fully reversed trapezoidal strain wave at a frequency of 0.25Hz. The depth of the LCF cracks at the surface was comparable to that of the secondary dendrite arms from the surf-ace of the specimen. Cracks initiated at all of the interdendritic regions exposed at the surface, especially at the v-v' eutectic phase. LCF crack initiation and propagation are therefore proposed to be microstructally dependent.
체외충격파 쇄석술 시행 후 5년 뒤 발생한 요관 협착 및 농신장 1예

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

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.
