buer layer showed a signicantly clean surface with mirror-like morphology. From the results of photoluminescence measurements at room temperature, UV emission originating from near-band-edge emission was observed for the mirror-like Zn0:93Mn0:07O thin lms, while the columnar-structured Zn0:93Mn0:07O thin lms were optically poor. The mirror-like Zn0:93Mn0:07O thin lms clearly showed a hysteretic behavior for the measurement of magnetization, which is obvious evidence of ferromagnetism. The columnar-structured

Background/Aims: The blended current is usually used for endoscopic sphincterotomy (EST) to minimize bleeding. The pure cutting current may induce less edema of the ampulla and therefore result in less injury to the pancreas theoretically. The aim of this study was to evaluate effects of electric currents used on the development of serum pancreatic enzyme evaluation, clinical pancreatitis or bleeding after EST. Methods: One hundred and eighteen consecutive patients who underwent EST with standard papillotome alone for the treatment of choledocholithiasis were reviewed. All EST had been performed by two endoscopists whose experience on EST was similar: one uses blended current(BC group, n=74), while the other uses pure cutting current (PC group, n=44). Results: Baseline clinical, laboratory, and procedural parameters were similar in both groups. The incidences of hyperamylasemia and hyperlipasemia were similar between two groups. There was no significant difference in the incidence of clinical pancreatitis between two groups (BC 6.8% vs PC 0.0%, p=0.1557). All episodes of pancreatitis were mild. No episodes of significant bleeding occurred after EST. The incidences of sepsis, cholangitis and perforation were also not different between two groups. Conclusions: Development of complications after standard EST such as hyperamylasemia, clinical pancreatitis, and bleeding may not depend on the electric current used.

Emphysematous cholecystitis is an unusual variant of acute cholecystitis caused by gas-forming organisms. It is characterized by the presence of gas in the gall bladder lumen, wall or pericholecystic tissues. It is thought to be a rare but life-threatening disease with high morbidity and mortality rates than those for other types of acute cholecystitis. Management of emphysematous cholecystitis is surgical removal of gallbladder. Recently, percutaneous cholecystostomy drainage is employed in patients with complications such as perforation and in those who have high surgical risk. It is demonstrated to lower the surgical mortality rates, but it still does not obviate the need for surgical removal of the gallbladder. Percutaneous cholecystostomy may be used for definite therapeutic procedure of emphysematous cholecystitis and we report a case of emphysematous cholecystitis that was cured by the percutaneous cholecystotomy without surgical procedure.

Heterotopic pancreas, defined as the presence of pancreatic tissue that lacks anatomic and vascular continuity with the pancreas proper, may be more likely to undergo malignant change. However, malignancy arising from heterotopic pancreas is rare. In Korea, only one case of adenocarcinoma arising from a gastric heterotopic pancreas has been reported. Recently, we experienced a case of duodenal carcinoma arising from heterotopic pancreas in a 64-year-old man. Endoscopic biopsy of the stenotic duodenum was positive for adenocarcinoma, and he underwent a pancreaticoduodenectomy with subtotal gastrectomy. Histologic examination of the resected specimen satisfied the proposed conditions that are necessary to prove that a malignancy arose from heterotopic pancreas. Despite an adjuvant chemotherapy, he died 10 months after surgery. Herein, we report a case of duodenal adenocarcinoma arising from heterotopic pancreas with a review of the relevant literature.

The Collapsing cases of greenhouse in rural area have been increased due to the unexpected heavy snow load. reproduction. However, the damages of collapses of greenhouse repeat annually. In this paper, in order to examine the effect of side wall incline, side wall height and roof curvature of the greenhouse during the heavy snow falling period, the limit analysis using CPM (Compact Procedure Method) which uses in actual collapse case carried out.

N/A Background/Aims: The serum tumor markers, such as CEA and CA19-9, for gastric cancer have been used but their positive rates are not high. In this study the value of a new serum marker, CA72-4, was compared with the serum activities of CEA and CA19-9 in a consecutive series of patients with gastric cancer. Methods: Fifty-three patients(35 men and 18 women; mean age, 60 years) with histologically diagnosed adenocarcinoma of the stomach, were evaluated. Serum TAG-72 antigen was determined by a double determinant radioimmunometric assay kit, CA72-4, and serum CEA and CA19-9 levels were also measured. Results: CA72-4 had a very high specificity(100%) for benign gastric disease. In gastric carcinoma, the positive rate of CA72-4 was 28% and was not so different to that of CA19-9, 34%, and CEA, 32%. There was significantly increased positive rates of CA72-4, CA19-9 and CEA in patients with advanced gastric cancer than those with early gastric cancer(p<0.01) but no significant difference in CA72-4, CA19-9 and CEA. There was no significant difference in positive rates of CA72-4, CA19-9 and CEA in patients with distant metastases or lymph node metastases than those without metastases. The positive rates of combined use of serum CA72-4 and CA19-9, CA72-4 and CEA, and CA72-4, CA19-9 and CEA were 43%, 45% and 51%. Conclusions: The results of this study suggest that CA72-4 is not better in the serodiagnosis of gastric cancer than conventional tumor markers, CA19-9 and CEA. However, despite considerable numbers of advanced gastric cancer patients with positive CA72-4, there is little clinical significance of CA72-4 in the serodiagnosis of gastric cancer.
