Acute tubular necrosis has been rarely reported as a complication of typhoid fever in the literature. We experienced four cases of acute tubular necrosis associated with typhoid fever in children. Patients showed significant titer of widal reaction associated with acute renal failure and one of them rised in 2 months after onset of clinical symptoms. Renal biopsy findings were compatible with acute tubular necrosis and immune complexes were not deposited in the glomeruli. Clinical and urinary findings were normalized by hemodialysis and antibiotic therapies. In conclusion, close longterm follow up of widal titer is mandatory in acute tubular necrosis, especially when associated with high fever.

The purpose of this study was to observe the tissue response to the orthodontic force applied immediately after buccal horizontal subapical osteotomy of maxilla. Five mongrel cats weighing about 2.5 Kg were used for this experiment. The left upper canine and premolar of each cat served as a experimental side and the right ones as a control side. On the experimental side, a 100gm orthodontic force was applied between the upper canine and premolar immediately after the osteotomy. On the control side, the same orthodontic force was applied without the osteotomy. After 7days, the experimental animals were sacrificed. The results were as follows: 1. In the pressure zones of the experimental group, significant increase of osteoclasts and direct resorption along the alveolar bone surface was observed as compared with those of the control group. 2. In the pressure zones of the experimental group, a less extensive hyalinized zone was observed than those of the control group. 3. In the pressure zones of both group, no root resorption was found. 4. In the tension zones of the experimental group, new bone deposition increased along the alveolar bone surface as compared with those of the control group. In conclusion, the results suggest the possibility that early orthodontic treatment after orthognathic surgery may have some benefits if the stability of the repositioned segment at surgery is secured.

The complications of bile duct stone are cholangitis, pancreatitis, obstructive jaundice, liver abscess, and secondary biliary cirrhosis. Liver abscess may produce pyothorax, peritonitis, subphrenic abscess, and pyogenic pericarditis. The case studies of pyogenic pericarditis secondary to pyogenic liver abscess are rarely reported. Stones greater than 20mm in diameter are difficult or impossible to remove with a standard basket or balloon after sphincterotomy. There are several nonsurgical treatment options for large bile duct stone: mechanical lithotripsy, endoprosthesis, extracorporeal shock-wave lithotripsy (ESWL), electrohydraulic lithotripsy, contact dissolution therapy, and laser lithotripsy. We experienced a case of large bile duct stone which complicated by pyogenic pericarditis, liver abscess, and pyothorax. He treated with antibiotics, closed thoracostomy, partial pericardiectomy, and removal of bile duct stones by extracorporeal shock-wave and mechanical lithotripsy after endoscopic sphincterotomy and nasobiliary drainage.

Dieulafoy lesion is very small and easily overlooked as a course of massive, often recurrent hemorrhage that results from the crosion of a submucosal artery, typically in the gastric cardia or fundus. The clinical picture of Dieulafoy lesion is quite uniform: patients commonly present with massive hemorrhage and melena without any relevant history. The diagnostic procedure of choice in patients with severe gastrointestinal bleeding is emergency endoscopy. The lesion is rare but potentially life threatening source of upper gastrointestinal bleeding. Before the endoscopic era, the prognosis for patients with these lesions was quite poor. However, recent reports have described the success of endoscopic therapy in the management of Dieulafoy lesion. We performed emergency endoscopy in 3 patients who had massive or recurrent episode of upper gastrointestinal bleeding, identified to the Dieulafoy lesion. We tried to Endoscopic "0" band ligation, successfully in hemostasis and prevention of recurrence.

There has been so much controversies about the position of upper and lower jaws, and their first permanent molars in normal occlusion and Angle's class I,II,III malocclusions. So, the purpose of this study is to compare the position of upper and lower jaws, and their first molars in normal occlusion and Angle's class IIIIII malocclusions by lateral cephalometric analysis. The sample consisted of one hundred and twenty girls(thirty in each group) who had completed growth. The findings of this study were as follows: 1. In class I malocclusion, both maxilla and mandible were slightly posterior position than normal occlusion, but they showed harmonious relationship. 2. In class II malocclusion, the mandible was greatly retruded, and the maxilla was also slightly retruded to the cranial base as compared with normal occlusion. 3. In class III malocclusion, the maxilla was significantly retruded to the cranial base, but no significant difference was found in mandibular position as compared with normal occlusion. 4. The maxillary first molar was located at posterior position in class II malocclusion, and anterior position in class III malocclusion to the cranium, so that the rotation of mandible was influenced by that. 5. The mandibular first molar showed constant relationship to the mandible in all four groups, but different position to the cranial base in direct proportion to the mandibular position. 6. On the treatment planning of class II malocclusion, it seems to be better to promote the mandibular horizontal growth by inhibiting the vertical growth of maxillary molar area, and on the treatment planning of class III malocclusion, it seems to be better to promote the antero-inferior growth of maxilla and to promote the mandibular vertical growth by inducing the vertical growth of maxillary molar area.

BACKGROUND: An increase in oxidative stress has been suggested to play major roles in the complications of diabetes. The bulk of the experimental data favors enhanced free radicals in diabetes and antioxidant defense mechanisms may be reduced in diabetes. Melatonin, the major secretory product of the pineal gland has been shown to be a potent and specific hydroxyl radical scavenger. The purpose of our study was to determine the antioxidative effeet of melatonin in streptozotocin-induced diabetic rats. METHODS: Sprague-Dawley rats weighing 200-240 g were divided into 3 groups: normal controls(n-7), diabetic contmls(n-9), melatonin-treated diabetic animals(n-9). Diabetes was induced by intraperitoneal injection of streptozotoein(55 mg/kg body weight) and melatonin(6 mg/kg body weight) was orally administered for 20 days. At day 20 after streptozotocin administration, blood was collected for the assay of glucose, albumin and cholesterol. Erythrocyte membrane lipid peroxidation was determined by malonyldialdehyde(MDA) reactivity. RESULTS: 1) The MDA resctivity of erytbrocyte membrane in melatonin-treated diabetic animals (meanstandard deviation: 5.52+-1.52nmol/ml packed cells) were lower(p<0.05) than that in diabetic controls(7.68+-1.16nmol/mL packed cells). But, there was no significant difference between melatonin-treated diabetic animals and normal contls(4.93+-1.19 nmol/mL packed cells). 2) There were no significant differences of blood glucose and body weight between diabetic controls and melatonin-treated diabetic animals. CONCLUSION: These results show the antioxidative effect of melatonin in streptozotocin-induced diabetic rats. Further clinical and long-term experimental studies are needed to assess the effect of melatonin on development and progression of diabetic complications.

Foreign body aspiration into the airway causes airway obstruction that may be acutely life-threatening or if undected result in severe lung damage. In case of bilateral bronchial obstruction, the impairment of gas exchange is usually severe enough to threaten the patient's life. And the gas exchange will become worsen during bronchoscopy. So, anesthesia and bronchoscopy for removal of the foreign body should be carried out by skilled personel with appropriate equipment, especially in case of bilateral bronchial obstruction. A 16 month old, cyanotic and dyspneic female infant was brought to operating room for removal of bronchial foreign bodies . The anesthesia was induced and maintained with enflurane(1-2%) -oxygen(100%)- vecuronium using Jackson- Rees breathing system which was connecting to the side arm of ventilating brochoscope. Foreign bodies (peanut), which were two pieces of peanut 4X4X6 mm sized from right and 4X8X12 mm sized from left main bronchus, were sucessfully removed.
