  • Although nonoperative reduction plays a major role in the management of uncomplicated intussusception in the pediatric age group, surgical treatment is still a necessary alternative when nonoperative reduction is unsuccessful. The author analyzed the clinical features of 68 patients requiring operation in order to identify factors which might influence the type of operative management. A nine-year experience at Ewha Womans University Hospital was reviewed, and the findings compared to previous reports. Barium was used for the initial reduction attempt in 33 cases, saline in 35. Manual reduction by milking at operation achieved success in 41 cases(60.3%). Fifteen cases(22.1%) required resection of bowel, and 12 patients(17.6%) were found to have spontaneous and complete reduction of the intussusception at operation. Two cases had pathologic leading points. There were no perforations due to nonoperative reduction. There were no significant differences in demographic data, clinical findings, laboratory data, and anatomic type of intussusception between barium and saline reduction groups. However, a significant number of cases with spontaneous reduction were in saline reduction group(p<0.05). There was a slight chance of spontaneous reduction in infants under 6 month of age(p<0.001). Age under 6 month. body temperature over $38^{\circ}C$, symptom over 24 hours, and ileo-colic and ileo-ileo-colic intussusception contributed significantly to the necessity for bowel resection(p<0.05-0.001). The author believes that the age, body temperature, duration of illness, and anatomic type of intussusception strongly influence operative management.

  • The effect of reduction and re-oxidation firing on the PTCR properties of Sm-doped Barium Titanate ceramics was investigated for the application of multilayered PTC thermistor. The lattice parameter a, c decreases monotonically with increasing oxygen concentration in the reoxidation atmosphere, which seems to be related with the electrostatic Coulomb interaction between oxygen vancancy and nearest other atoms. With increasing oxygen concentration, the resistivity at room temperature and the magnitude of resistivity jump as a function of temperature increased in the region of oxygen concentration of 0 $\sim$ 10%. However, the resistivity at room temperature and the magnitude of resistivity jump is nearly constant and saturated in the region of oxygen concentration of 10 $\sim$ 20%. These phenomena is considered to be related with the variation of oxygen and barium-vancany concentration near the grain boundary.

  • The purpose of this present study was to evaluate the surface radiation dose reduction and radiograph artifact images in computed tomography (CT) for the manufactured radiation shields by using sea-shells. The radiation convergence shields were made from silicons, sea-shells, barium powders, producted circle types of diameter 50 mm, thickness 3.5 mm for 5 kinds (only silicon shield, only barium shield, mixed sea-shells with silicon shield, mixed barium with silicon shield, mixed sea-shells with barium and silicon shield). Radiation generation and acquisition were used 4-channel multi-detector CT. The results of this study showed that mixed sea-shells with silicon shields could reduce the surface dose of 5.3% without radiograph artifact images. In the future, we will expect the radiation convergence shield as environmentally friendly materials by using the recycling of sea-shells with the advantages of silicon which can make various shapes.

  • The efficacy of Arque-Ajeeb (AA), a compound formulation of Unani medicine was investigated for antidiarrhoeal activity against barium sulphate-induced gut motility and castor oil-induced diarrhoea in rats. The control, standard and test groups of experimental animals were administered with distilled water (p.o.), lomotil (p.o.) and AA (0.007 ml and 0.014 ml/100 g, p.o.) respectively. Barium sulphate and castor oil were administered after 15 and 60 min respectively in each group of first and second experiment. The distance traveled by barium sulphate in small intestine was measured after 15 and 30 min of barium sulphate administration and diarrhoea was observed every 30-min for six hour after castor oil administration. Oral administration of AA caused significant reduction in diarrhoea. AA may have the potential to reduce the diarrhoea in rats.

  • Intussusception is common cause of intestinal obstruction in children. Most of intussusceptions can be treated with non-operative reduction using air or barium. However, about 10% patients need operative treatment due to failure of reduction, peritonitis, and recurrence after reduction. We introduce our experience of laparoscopic surgery for intussusception. From April 2010 to March 2013, we reviewed 57 children who diagnosed intussusception. Twelve patients underwent an operation. The cause of operation was 7 of failure of air reduction and 5 of recurrence after air reduction. Median age was 21.5 months (range: 5.0~57.7 months) and 11 children (91.7%) underwent successful laparoscopic reduction. Median operating time was 50 minutes (range: 30~20 minutes) and median hospital days was 4.5 days (range: 3~8 days). One patient had a leading point as a heterotopic pancreas and underwent bowel resection through conversion. There was neither intra-operative nor postoperative complication. Laparoscopic reduction for intussusception can bring an excellent cosmetic effect with high success rate.

  • A 70-year-old female patient was admitted due to the impression of lung abscess via local clinic. Chest P-A showed air shadow containing huge mass lesion in the right lower lung field, pericardio phrenic angle. But the patient complained of only mild upper respiratioy tract infection symptoms and the laboratory tests were within normal limits. Barium enema and chest C-T taken right after barium enema were performed in suggestion of the diaphragmatic hernia. Barium filled transverse colon and associated omentum were in the right anterior hemithorax surrounded by the hernial sac. The mass lesion shown in the chest P-A was compatible with the diaphragmatic hernia, Morgagni type. Operative reduction of the herniated bowel and simple closure of the diaphragm was performed.

  • This study provides an assessment on a proposed method for separation of cesium, strontium, and barium using electrochemical reduction at a liquid bismuth cathode in LiCl-KCl eutectic salt, investigated via cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS). CV studies were performed at temperatures of 723-823 K and concentrations of the target species up to 4.0wt%. Redox reactions occurring during potential sweeps were observed. Concentration of BaCl2 in the salt did not seem to influence the diffusivity in the studied concentration range up to 4.0wt%. The presence of strontium in the system affected the redox reaction of lithium; however, there were no distinguishable redox peaks that could be measured. Impedance spectra obtained from EIS methods were used to calculate the exchange current densities of the electroactive active redox couple at the bismuth cathode. Results show the rate-controlling step in deposition to be the mass transport of Cs+ ions from the bulk salt to the cathode surface layer. Results from SEM-EDS suggest that Cs-Bi and Sr-Bi intermetallics from LiCl-KCl salt are not thermodynamically favorable.

  • An eight-month-old, intact female Jindo, weighing 9 kg with a one-day history of acute bloody diarrhea was referred. Plain abdominal radiographic findings included evidence of a soft tissue tubular mass within the dilated colon. In ultrasonographs, a target-like mass was identified with multiple hyperechoic and hypoechoic parallel wall layers. A barium enema showed a large radiolucent filling defect within the colon and a completely occlusive lumen. On the basis of these images, ileocecocolic and colocolic intussusception was diagnosed. Surgical manual reduction, resection and anastomosis were performed. The patient recovered normally without any complications or recurrence.

  • To evaluate the clinical findings of the recurrent intussusception, 351 patients with 445 intussusceptions were reviewed. Recurrence rate, pattern of recurrence, reducibility, pathologic lead points (PLP), and operative findings and long term follow up of the multiple recurrences were analyzed. Of 351 patients, 303 had no recurrence, 26 had one recurrence, and 22 had multiple recurrences. Over all recurrence rate was 16.4% ; 18.5% were managed by air reduction, 16.2% by barium reduction and 5.9% by operation. Eleven PLPs were proved operatively and an additional 6 suspected PLPs were depicted radiologically. The most frequent PLP was ileal lymphoid hyperplasia. Intervals between reduction and recurrence were less than 2 weeks in 31 cases, between 2 weeks and 1 year in 55, and more than 1 year in 8. The longest interval was 2 years and 4 months.
