Isolated injury to the pancreas after abdominal trauma is uncommon, and a delay in diagnosis and treatment can increase the morbidity and mortality. Therapeutic decisions with respect to pancreatic trauma are usually made based on the site of injury and the status of the pancreatic ductal system. In this report, we describe the surgical management of pancreatic head transection as an isolated injury following blunt abdominal trauma. A 55-year-old man presented with epigastric pain that radiated to the back. Abdominal computed tomography revealed a hematoma in the pancreatic head and upstream dilatation of the main pancreatic duct. Endoscopic retrograde cholangiopancreatography showed complete disruption of and contrast leakage from the main pancreatic duct in the pancreatic head region with a nonenhanced upstream duct. Emergency pancreaticoduodenectomy was successfully performed, and the patient was discharged on postoperative day 9 without any complications.

Azadirachtin은 Leucophaeq muderae (Fabricius연 하루 활동주기길이를 0.16 $\pm$ 0.03 h 단축시켰으며, 실험동물의 40 %에서 리듬의 Splitting현상이 관찰되었다. 하루에 두개의 활동주기를 보이는 Splitting현상은 서로 180$^{\circ}$를 유지하여 나타났고, 이는 동물의 실험 전의 본래 주기길이가 평균보다 더 긴 주기를 지닌 동물에게 주로 나타났다. 또한 활동주기의 Splitting현상을 보이는 동물의 안구와 뇌신경(optic lobe) 절단수술 후 Splitting이 사라짐으로써 Azadirachtin이 뇌신경에 자극을 주어 Splitting을 야기시켰으며, 한쌍의 optic lobe 중 어느 한쪽만으로도 동물의 활동주기 조절가능성이 있다는 것이 본 실험을 통하여 밝혀졌다. Azadirachtin shortens the period length of the locomotor activity rhythm in the circadian rhythm of Leucophoeo maderae and induces splitting of this rhythm in ho components in about 40% of the animals. The phase relationship between the ho components is 180$^{\circ}$Both shortening of period and splitting are more pronounced in animals processing longer periods before the injection of azadirachtin. Splitting disappears after the surgical transection of optic lobe.

A 18-year-old female underwent surgical correction of tricuspid atresia and complete transposition of great arteries combined with atrial 8 ventricular septal defect and pulmonary stenosis. After the transection of main pulmonary artery just above the pulmonic valve, proximal portion of main pulmonary artery was closed with running suture and distal portion of main pulmonary artery anastomosed with right atrial appendage without valve insertion. Atrial septal defect was closed with running suture. Postoperative course was uneventful and she discharged on 18th postoperative day. Her condition is in very good until present. Modified Fontan`s operation without valve placement [in the condition of low pulmonary vascular resistance and good left ventricular function] may has a good result.

A 5-week old Thoroughbred foal was presented with severe left carpal valgus. Radiographs of the dorsopalmar projections confirmed the deviation was 14 degrees. Surgery using a single-position screw traversing the physis of the distal radius was performed. The limb was almost straight (2 degrees) 3 weeks after surgery. Visual/radiograph follow-up 7 months after screw removal revealed no over-correction after removal of the screw. Transphyseal bridging using a single-position screw without lateral periosteal transection of distal radius was successful for the correction of foals with this condition.

This study was performed to assess therapeutic effect of the tibial plateau leveling osteotomy (TPLO) in dogs with experimentally transected cranial cruciate ligaments (CrCL). Nine healthy adult Beagle dogs were transected left CrCL under general anesthesia. The dogs were assigned to TPLO and non-TPLO control groups. The TPLO procedures for correcting the CrCL rupture in the left stifle of dogs were performed under sterile conditions. Before TPLO procedures, all dogs were screened by orthopedic and radiographic examinations. Dogs were lameness free for the previous three months, and when examined at the walk and trot on a hard surface, in a straight line and on a circle. Lateral and craniocaudal radiographs were done to confirm the soundness of the both knee joint in dogs and not detectable lesions were diagnosed. The dogs were intravenously injected with a 10 mci/kg of 99mTechnetium-methylene diphosphonate (99mTc-MDP) under general anesthesia. Scintigraphs were obtained using a large field of view gamma camera equipped a parallel-hole, low-energy about 3 hours after intravenous injection of 99mTc-MDP. Before CrCL transection and 4, 8, and 12 weeks after the procedures, scintigraphy were conducted. Bone uptake of the left stifle joint increased after the procedures in all dogs. When the bone uptake from the TPLO procedure was compared with that of the control, there was a significant difference (p < 0.05). At 12 weeks after the TPLO procedure, the dogs showed normal anatomical posture and gait. It is concluded that TPLO procedure was effective in reconstruct of the stifle joint in dogs with CrCL rupture.

Objectives : The effects of a combined stimulation of 658 nm, 830 nm, 904 nm, and 1064 nm laser acupuncture treatment (LAT) and electroacupuncture treatment (EAT) on GB39 and GB34 on neuropathic pain in rats induced by tibial and sural nerve transection were studied in this paper. Methods : To express a neuropathic pain model, surgery was performed to transection rats' tibial and sural nerves. The rats were divided into normal group, control group, and experimental groups. In addition, the experimental groups were divided into 658 nm laser and electroacupuncture (LAT658+EAT), 830 nm laser and electroacupuncture (LAT830+EAT), 904 nm laser and electroacupuncture (LAT904+EAT), and 1064 nm laser and electroacupuncture (LAT830+EAT). For the treatment of the experimental groups, electroacupuncture and different laser wavelengths were alternately applied to GB34 and GB39 twice a week for 3 weeks for 1 minute 30 seconds. The withdrawal response of neuropathic rats' legs by acetone stimulation was observed, as well as the c-Fos in the central gray region in the midbrain of neuropathic rats together with Bax, Bcl2, and mGluR5 expressions associated with apoptosis. Results : Compared with the control group, a significant decrease in the frequency of paw withdrawal in response to acetone allodynia was observed in LAT658+EAT and LAT830+EAT groups in 6th times, LAT904+EAT group in 2^nd, 3^rd, and 6^th times, and LAT1064+EAT group in 2^nd and 6^th times, respectively. For c-fos positive cells in the central gray region, a significant decrease was observed in LAT830+EAT, LAT904+EAT, and LAT1064+EAT groups in comparison with the control group. In Bax expression, LAT1064+EAT group showed a significant decrease compared to the control group. In Bcl-2 expression, the LAT658+EAT,the LAT904+EAT, and the LAT1064+EAT groups increased significantly compared to the control group. LAT830+EAT, LAT904+EAT, and LAT1064+EAT groups showed significantly increased mGlu5 expression compared to the control group. Conclusions : The combination of laser for each wavelength and electroacupuncture alternately performed in this study is thought to be effective in improving neuropathic pain and apoptosis.

Fibrothorax is the end stage of chronic pathologic processes of pleura such as hemothorax, empyema, or tuberculous effusion. The pleural space become adherent and obliterated, and the lung parenchyma is covered by a thick, fibrous, unexpandable "peel", so the lung function is diminished markedly with impaired ventilation and oxygenation. Constrictive pericarditis is often accompanied fibrothorax, also cardiac and hemodynamic function is deteriorated. Surgical relief of these fibrous peels causes remarkable improvement in pulmonary function, cardiac and hemodynamic function, and subjective symptoms. We experienced a case of bilateral fibrothorax combined with constrictive pericarditis which occured 3 years after bilateral tuberculous effusion. Decortication and percardiectomy were done at the same time through bilateral submammary thoracotomy with sternal transection. Comparing postoperative Peripheral venous pressure, Circulation time, Pulmonary function test, Arterial blood gas analysis, Subjective symptoms with preoperative conditions showed noticeable improvement.provement.

Burner or stinger syndrome is a rare sports injury caused by direct or indirect trauma during high-speed or contact sports mainly in young athletes. It affects peripheral nerves, plexus trunks or spinal nerve roots, causing paralysis, paresthesia and pain. We report the case of a 57-year-old male athlete suffering from burner syndrome related to a lumbar nerve root. He presented with prolonged pain and partial paralysis of the right leg after a skewed landing during the long jump. He was initially misdiagnosed since the first magnet resonance imaging was normal whereas electromyography showed denervation. The insurance company refused to pay damage claims. Partial recovery was achieved by pain medication and physiotherapy. Burner syndrome is an injury of physically active individuals of any age and may appear in the cervical and lumbar area. MRI may be normal due to the lack of complete nerve transection, but electromyography typically shows pathologic results.
