The Taekwondo being a martial sports, there are higher chances for the injury to occur than the non martial sports. Therefore, this study analyze the frequency, the area, the type, and the condition of the injury which are prone to occur in the Taekwondo matches; it is to help the Taekwondo players in prevention of the injury and in treatment. The subjects of this study were the 48 players (male 24, female 24) who participated in the final selection contest of the national team player on March 9 to 12, 1993. The data of the injury were obtained from the medical recoder staff and were analyzed to the frequency of the injury per match, the vulnerable area of the injury, the type of injury, and the condition of the injury with a gender difference. There were 24 matches for the male and 24 matches for the female, total 48 matches. Therefore, the total participation number of the players are the double of the match number. 1. The frequency of the injury per match was 18.3%(11/60) for male and 23.1%(12/52) for women. 2. The areas of the injury were ankle 36.4%(4), foot 18.2%(2), knee 18.2%(2), lower leg 18.2%(2), wrist 9.1%(1) in male; foot 33.4%(4), ankle 16.7%(2), knee 16.7%(2), lower back 16.7%(2), lower leg 8.3%(1), face 8.3%(1) in female. 3. The types of the injury were contusion 45.5%(5), sprain 27.3%(3), abrasion 9.1%(1), laceration 9.1%(1), tendon rupture 9.1%(1) in male; contusion 33.3%(4), sprain 33.3%(4), abrasion 16.7%(2), subcutaneous hemorrhage 8.3%(1), dislocation 8.3%(1) in female. 4. The condition of the injury were the unblocked attack 36.4%(4), attacking kick 27.3%(3), blocking a kick 18.2%(2), attacking punch 9.1%, impact with surface 9.1%(1) in male; attacking kick 33.3%(4), unblocked attack 25%(3), blocking a kick 25%(3), attacking punch 8.3%(1), impact with surface 8.3%(1) in female. This study shows that the injury from the Taekwondo matches occurred most in the lower extremity joints and the foot, and shows that the most of the injury types were contusion and sprain. Therefore, it is believed to be helpful to wear the proper fitting ankle or the knee protector and using other protective equipment to prevent the sports injury in the Taekwondo matches.

Still a lethal injury, traumatic rupture of thoracic aorta occurs more frequently than we expect and comprises significant part of causes of deaths by blunt trauma. We recently experienced a thoracic aortic rupture accompanied by multiple injuries including pericardial and interatrial septal rupture and myocardial contusion in a patient who had been injured in a fall accident. Literatures are reviewed with the concern of early diagnosis, surgical technique and the result of operation.

During the period of 4 years from August 1, 1975 to August 1, 1979, authors have experienced 100 cases of multiple rib fractures by nonpenetrating injury at Department of Thoracic Surgery, Paik Foundation Hospital in Seoul, Korea. 1. The ratio of male to female patients with multiple rib fracture was 2.6:1 with male predominance and 84% of the total cases were between 20 and 50 years of age. 2. The most common cause of multiple rib fracture was traffic accident and falls accounted for the next largest group. 3. The most common site of rib fracture was 4th rib to 7th rib level on both hemithorax [52%]. 4. Associated injuries were cerebral contusion in 26%, clavicular fracture in 22%, long bone fracture in 22%, pelvic bone fracture in 10%, and scapular fracture in 8%. 5. Early complications and/or result of the multiple rib fractures were lung contusion in 23 cases, subcutaneous emphysema in 21 cases, hemothorax in 21 cases, hemopneumothorax in 6 cases, and flail chest in 12 cases. 6. The flail chests were managed by strapping the chest with adhesive plaster, external traction of flail segment with towel clip, ventilatory assistance for marginal clinical indications, and in cases of complicated with intrathoracic hemorrhage, wire fixation of flail segment through open thoraco-tomy. 7. The principles of therapy for hemothorax and/or pneumothorax were rapid reexpansion of the lungs by thoracentesis [11%] and closed thoracostomy [22%], but open thoracotomy had to be done on 3 cases because of massive bleeding or intrapleural hematoma and diaphragmatic rupture. 8. The over all mortality was 4% [4 among 100 cases] and the cause of all deaths was head injury.

Eleven cases of peripheral arterial injuries treated at Korea University Woo Sok Hospital during these 3 years and 3 months from Feb. 1971Eleven cases of peripheral arterial injuries treated at Korea University Woo Sok Hospital during these 3 years and 3 months from Feb. 1971 to May 1974 were reviewed. Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries during operation. Of the 11 arterial injuries 3 were femoral artery which` was the commonest in frequency and the next was 2 cases of brachial artery. The most frequent type of injury was transection. Laceration, contusion and spasm was also recognized. The need to operate immediately following an injury was emphasized. Operative procedures were end to end anastomosis and saphenous vein graft in 5 and 2 cases, respectively. Other cases were undergone multiple suture ligature due to staphyllococcal infection, insertion of polyethylene catheter, and lateral suture after thromboendarterectomy. Fractures and extensive soft tissue damage associated with arterial injuries with widespread destruction of the collateral circulation aggravated the situation and complicated the amputation of lower extremity in 4 cases. The factors influencing the amputation were time lag, presence of associated injuries and complications.[KTCS 1974;1:109-116] Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries during operation.

The aim is to investigate the analgesic effect of transcranial direct current stimulation(tDCS) on central neuropathic pain(CNP) in spinal cord contusive rat model. Twenty Sprague-Dawley rats($250{\pm}50$ g, male) were used. Thoracic spinal cord(T10) was contused using New York University(NYU) spinal cord impactor. The animals were randomly assigned to two groups; GroupI: Non-treatment after SCI induction(n=10), GroupII: application of tDCS(0.1 mA, 20 min/time, 2 times/day, 5 days/6week) after SCI induction(n=10). Assess the effect of tDCS using the Basso Beattie Bresnahan(BBB) locomotor rating scales, Touch $test^{TM}$ sensory evaluator(TTSE), Plantar test$^{\circledR}$after contusion at the $2^{nd}$, $3^{rd}$, $4^{th}$, $5^{th}$, $6^{th}$ week and the immunohistochemistric response of c-fos in the thalamus, cerebral cortex after contusion at the $3^{rd}$, $6^{th}$ week after SCI. The scores of BBB scales were significantly different from $3^{rd}$week. TTSE were different significantly over time, but there were no differences at each evaluation times on between-measure time effects. Plantar test were different significantly over time and there were difference at the $4^{th}$, $6^{th}$ week after SCI on between-measure time effects. Also, immunohistochemistric response of c-fos was reduced significantly from $3^{rd}$, $6^{th}$ week after SCI in tDCS group compared with control group in thalamus and cortex. These results identified that tDCS of non-invasive therapeutic method may have beneficial analgesic effect on CNP after SCI with behavioral test and immunohistochemical test.

A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

Objectives : This study was performed to evaluate the effects of root of Scutellariae Radix(SR) water extract against inflammatory response in the spinal cord injury(SCI). Methods : SCI was induced by mechanical contusion following laminectomy of 10th thoracic vertebra in Sprague-Dawley rat. SR was orally given once a day for 7days after SCI. Myeloperoxidase(MPO) positive neutrophils infiltration was examined. Inducible nitric oxide synthase(iNOS) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) expressions were observed with immunohistochemistry. Glial fibrillary acidic protein(GFAP) positive astrocytes were examined using immuno-fluorescence. Results : 1. SR reduced MPO-positive neutrophils infiltration in peri-damage regions of the contusive SCI-induced rats. 2. SR reduced iNOS positive cells in the white matter of the contusive SCI-induced rats. 3. SR reduced TNF-${\alpha}$ positive cells in the gray and white matter of the contusive SCI-induced rats. 4. SR reduced cell number and size of astrocytes in peri-damage regions of the contusive SCI-induced rats. Conclusions : These results suggest that SR plays an inhibitory role against inflammatory response in the SCI.

This study was performed to investigate the effects of Gwaluzisiltang and Gwaluzisiltanggami on the intravascular coagulation. The experimental group divided two groups : one group was the intravascular coagulation induced by endotoxin in rats, another group was the formation of paw edema by contusion in rats, and then these rats were treated with liquid extract of Gwaluzisiltang(Sample I) and Gwaluzisiltanggami(Sample II), which were administered orally. Then the numbers of platelets, concentration of fibrinogen, Prothrombin time and FDP(fibrin-fibrinogen degradation Products)were measured. The results were as follows : 1. The effects of the Intravascular coagulation 1) Platelet was increased significantly in the sample I compared with control group. 2) Fibrinogen was increased significantly in the sample I compared with control group. 3) Prothrombin time was shortened significantly in the sample I and more shortened in the sample II compared with control group. 4) FDP was decreased significantly in the sample I and more decreased in the samplem II compared with control group. 2. The effect of the formation of paw edema by contusion in rats. 1) The rate of paw edem was decreased significantly after five hours in the sample I 2) Platelet was increased significantly in the sample I compared with control group. 3) Fibrinogen was decreased in the sample I and sample II compared with control group, but it is not significant 4) Prothrombin time was shortened significantly in the sample II compared with control group. According to the above results, it is considered that the Gwaluzisiltang and Gwaluzisiltanggami seem to be applicable disease related to thrombosis, because they obtained significant effects on the experimental method which are based on the oriental medical theory-the principle of phlegm and blood stasis have the same source and disease (痰瘀同源, 痰瘀同病).

Purpose: In children, mild traumatic brain injuries (TBI) account for 70~90% of head injuries. Without guidelines, many of these children may be exposed to excess radiation due to unnecessary imaging. The purpose of this study was to evaluate the impact of a mild TBI guideline in imaging of pediatric patients. Methods: The medical records of all children who had head computed tomography and were admitted to our hospital with a TBI with Pediatric Glasgow Coma Scale and Glasgow Coma Scale of 14 to 15 were retrospectively reviewed and compared with PECARN Rule. Results: A total of 1260 children were included and all children checked with head computed tomography. 61 pediatrics had CT positive and presented skull fracture 40, hemorrhage 8, hemorrhagic contusion 7, and diffuse axonal injury 1. Also, 4 patients diagnosed both skull fracture and brain haemorrhage and 1 patient diagnosed both haemorrhage and haemorrhagic contusion. Conclusion: There are many pediatric traumatic patients who exposed to radiation due to CT. But, the most of results were negative. So, consider to follow the CT guideline for children and many do not require brain CT.
