This study was to investigate the protective and effects of Ikgukwhan and Ikgukbowhawhan on the liver cirrhosis or fibrosis induced by prolonged bile duct ligation; a new experimental model for cirrhosis and the intraperitoneal injection of dimethylnitrosamine in the rat. The development of fibrosis or cirrhosis and its inhibition by the two prescriptions were examined by the chemical analysis of AST, ALT, and hydroxyproline. The results obtained were as follows. 1. The increase of serum asparate aminotransferase induced by bile ductligation was inhibited by the administration of Ikgukwhan and Ikgukbowhawn extract. 2. The increase of serum alanine aminotransferase induced by bile duct ligation was inhibited by the administration of Ikgukwhan and Ikgukbowhawhan extract. 3. The increase level of serum AST and ALT induced by the intraperitoneal injection of dimethylnitrosamine was inhibited by the administration of Ikgukwhan and Ikgukbowhawhan extract. 4. The increase level of hydroxyproline volume in the damaged liver tissues in the rat was decreased by the oral administration of Ikgukwhan and Ikgukbowhawhan extract. But there were no significant differences in the inhibition rate between the two experimental groups.

Purpose: We wanted to evaluate the surgical results of early mobilization after rigid fixation of small coronoid fracture using the tension band technique Materials and Methods: Eight cases of coronoid fracture were fixed with the tension band technique and using K-wire and wire through the medial approach. All the cases were Regan-Morrey type 2. According to O'Driscoll, they were classified as 5 cases of the tip type (subtype 2) and 3 cases of the anteromedial type (1 case of subtype 2, and 2 case of subtype 3). The associated collateral ligament injuries (6 cases) and radial head/neck fractures (4 cases) were managed simultaneously. After immobilization for 5~7 days, active ROM exercise with a fitted hinge brace started and continued till postoperative 6 weeks. The patients were assessed for pain, ROM and functional disability using the Mayo elbow performance score (MEPS) at an average of 11 months (range: 6~28 months). The ulnar nerve symptoms were also investigated. Results: We observed solid union in all the coronoid fractures without hardware failure. An average of 2.2 wires (range: 2~4) were used. The mean extension was $3^{\circ}$(range: $0^{\circ}\sim25^{\circ}$), the mean flexion was $137^{\circ}$(range: $130^{\circ}\sim140^{\circ}$), the mean pronation was $69^{\circ}$(range: $45^{\circ}\sim90^{\circ}$) and the mean supination was $78^{\circ}$(range: $45^{\circ}\sim90^{\circ}$). The mean MEPS was 96 (range: 65~100). Ulnar nerve symptoms occurred at postoperative one day and persisted in one patient with the terrible triad of taking radial head excision and residual medial instability. Conclusion: The tension band technique uses easily obtained, economic K-wires and the wire was strong enough to permit early elbow ROM exercise and the technique might improve the elbow function. It was especially useful for fixation of multiple small fragments.

The authors surveyed extrafamilial sexual abuse in the children under 15years old by the physician's reports. We sent the semi-structured child sexual abuse questionnaires to 7055 board certified pediatrics, obstetrics and gynecology, family medicine and emergency medicine. Total respondents were 1205. The results from these respondents were as followings. 1) The number of respondents who have had the experience of treating victims of extraf/amilial child sexual abuse were 641(53.2% of total respondents). 2) 338(52.7%) of the perpetrators were known persons and 277(43.2%) were strangers, the most common age bracket were 20s, 30s and 10s, and almost all(99.8%) of the perpetrators were male. 3) The mean age of victims was $9.7{\pm}3.5$ years old, and almost all(98.6%) of the victims were female. 4) The ways by which extrafamilial child sexual abuses were found were victim’s own reports：273(62.6%), pain complaint, 156(24.3%) and abnormal behavior 96(15.0%), other person’s report 72(11.2%), detection during examination 19(3.0%), and pregnancy 4(0.6%). 5) Time lags between extrafamilial child sexual abuses and hospital visits were within 24 hours 332 (51.8%) and from 1 day to 1 week 232(36.2%), victims were rather quickly 6) Physical complications were perineal wound 571(89.1%), hymen rupture 349(54.4%), wound of other part of body 124(19.3%), pregnancy 37(5.8%), and sexually transmitted disease 18(2.8%), and other serious complications such as vaginal-rectal lacerations 8, intastinal bleeding 7, death 2, hypotensive shock 1. These results suggest considerable numbers of physicians have had the experience of treating victims of extrafamilial child sexual abuses, and extrafamilial child sexual abuses are the major medical as well as social issue in children in Korea.

Background: This study assessed the early results of endovascular repair of acute type B aortic dissection and the aortic wall changes following endovascular repair. Material and Method: From July 2008 to May 2009, the preoperative and follow-up computed tomography (CT) scans of 5 patients with acute type B aortic dissection were evaluated, and these patients had underwent stent graft implantation within 13 days of the onset of dissection (mean: 7 days; range: 3~13). The whole lumen (WL), true lumen (TL) and false lumen (FL) diameters were measured at the proximal (p), middle (m) and distal (d) third of the descending thoracic aorta. Result: The study included four men and one woman with an average age of $59.4{\pm}20.1$ years (age range: 37~79 years). The follow-up CT was performed and evaluated at 7 days and 6 months. The primary tear was completely sealed in all the patients. No paraplegia, paresis or peripheral ischemia occurred and none of the patients died. No endoleaks developed in any of the patients during follow-up. The TL diameters increased from 20.4 to 33.5 mm in the proximal third (p/3), from 19.5 to 29.8 mm in the middle third (m/3) and from 15.2 to 23.5 mm in the distal third (d/3). The FL diameters decreased from 18.7 to 0 mm in the p/3, from 15.4 to 0 mm in the m/3 and from 21.4 to 8.7 mm in the d/3. The changes in the TL diameter were statistically significant in the middle and distal aorta, and those changes in the FL diameter were not statistically significant. There was a decrease in the WL after repair, but this was not statistically Significant. In three patients, the false lumen disappeared completely on follow-up CT at 6 months. Two patients had patent false lumens and no thrombosis. Conclusion: The early results showed that endovascular repair was effective in treating acute type B aortic dissection, and endovascular repair promoted positive aortic wall changes.

Purpose: The purpose of this study is to describe causes and injury mechanisms during inline skating and to find preventive measures .Materials and Methods: We have carefully selected 57 patients who have been treated in our hospital and nearby hospital. There are 37 males and 20 females, and mean age is 9 years 9 months (range,6-40 years old) . We have meticulously investigated their injured sites, their favorite location for inline skating , their use of protective means while they were on the wheels and their injury mechanisms . Results: Injury consisted of 50 fractures,1 meniscal tear,2 medial collateral ligament rupture and 4 contusion or sprain. Fracture sites varied as follows : 33(66$\%$) cases in distal radius and ulna,5(10$\%$) in elbow. 3(6$\%$) in diaphysis of humerus, etc Location at the time of injury varied as follows : 22 cases(39$\%$) in their apartment complex, 19 cases in (33$\%$) narrow streets, and 16 cases(28$\%$) in parks Only five patients admitted that any means of protection were used.2 cases only had knee pad on , 1 case put on elbow pad in addition, and 2 cases put on wrist guard as well. However none of the patients had helmet on Conclusion: We would strongly like to stress the importance of using sufficient protections and of choosing area where it is safe to ride, in order to reduce the risk of accidents. In addition, continuous and effective prior education from inline skate circles may be in order before riding the inline skate.

Background: Multiple trauma patients have rapidly increased due to traffic accidents, industrial disasters, incidental accidents, and violence. Multiple trauma can involve injuries to the heart, lung, and great vessels and influence the lives, necessitate prompt diagnosis and treatment. Most of the thoracic injuries can be managed with conservative method and simple surgical procedures, such as closed thoracostomy, but in certain cases open thoracotomy is necessary. Materials and methods: The author analyzed the surgical result of 70 cases of open thoracotomy after multiple organ injury including thoracic organ. Results: The most common type of thoracic lesion was hemothorax with or without pneumothorax and diaphragmatic rupture was the second. Sixty percent of the patients were associated with bone fractures, 42.9% with abdominal injuries, and 37.1% with head injuries. The modes of operation were ligations of torn vessels for bleeding control(48.6%), repair of diaphragm(35.7%), and repair of lung laceration(25.7%) in this order of frequency and additional procedures were splenectomy(14.3%), hepatic lobectomy (8.6%) and repair of liver lacerations(5.7%). Postoperative complications were atelectasis (8.6%), wound infection (8.6%), and pneumonia(4.3%). Postoperatively six patients died(The mortality rate was 8.6%) and the causes of death were respiratory failure(2), acute renal failure(2), sepsis(1), and hypovolemic shock(1).

Spontaneous pneumothorax is rarely occurred as an initial sign of primary lung cancer. As a lot of these cases have already advanced, even then surgical resection is performed, the prognosis is often undesirable, We happened to find a ruptured cavity on a 65-year-old male patient who had suffered from pulmonary tuberculosis in the past, while performing VATS bullectomy for simple spontaneous pneumothorax, Then, as a result of frozen biopsy, it was diagnosed as squamous cell cancer Because the tumor was infiltrated from the upper lobe into the lower lobe passing by fissure, we should remove by pneumonectomy and the pathologic stage was found stage I(T2N0M0). When we made an follow-up observation for one year and a half, there was neither relapse nor complication. When there appears spontaneous pneumothorax to the high risk group for lung cancer who were smokers over forty-year old, with chronic bronchitis or pulmonary emphysema, it needs to have a closer observation on a base lung disease such as lung cancer through chest CT, and it is also necessary to make more active approach by performing the surgical operation through a thoracoscopy when there is a continued air release.

In recent years, the use of allograft conduits in repair of congenital cardiac disease is widely accepted. However, the supply of homograft. is currently limiting their increased clinical application, especially small cryopreserved homografts for use in neonates and inf'ants. We used a technique to surgically reduce the size of the more readily available large-diameter allografts, making them suitable for right ventricular outflow tract reconstruction in small infants and children. From December 1994 to March 1996, a total of 11 patients ranging in age from 10 months to 6 years (mean age, 27.3 months) and ranging in weight from 5.6 to 18.5 kg (mean 11.5 kg) underwent reconstruction of the right ventricular outflow tract using this surgical technique (pulmo ary atresia with ventricular septal defect, 9 cases ; tetralogy of Falloff, 2 cases). The diameter after downsizing ranged from 14 to 19 mm with a mean of 16.8 mm. There was one operative death due to rupture of the infected homograft. Evaluation of these patients between 2 and 15 months (mean 6.9 months) after homograft implantation reveals excellent clinical and echocardiographic results. There were no significant homograft insufficiency and RVOT obstructions. Although a longer follow-up is certainly required to evaluate the long term fate of the surgically modified bicuspid homografts, we believe that this technique may represent a valuable therapeutic alternative, at least in the short term, to the use of synthetic grafts when an appropriately sized homograft is not available.

Old newsprint was deinked with endoglucanase, exoglucanase and their various compositions from Trichoderma viride. The yield decreased with an increase in enzyme concentration. Especially, it was the lowest in the treatment of endo-exo mixture(1:1). It may be regarded as a synergistic actions of the cellulase components. The brightness was the highest in pulp deinked with endo-exo mixture(1:1). Maximum brightness was observed when 0.5mg/mL of the endo-exo mixture was used. The physical strength increased with increasing concentration in exoglucanase. But, it decrease with increasing concentration in endoglucanse and endo-exo mixture(1:1). Also, we investigated the yield, brightness and physical strength of endoglucanase in combination with exoclucanase(12:1, 8:1, 4:l, 1:1, 1:4, 1:8, 1:12). Maximal deinking conditions, obtained at a specific optimal ratio of endoglucanase to exoglucanse are as follow ; 12:1 for yield, 12:1 for brightness, 4:1 for tensile strength, 12:1 for bursting strength, and 8:1 for tearing strength. These results indicated that the deinking depended largely upon the action of endoglucanase. Exoglucanase was occupying more than 60% of the total crude cellulase contents. Therefore, the most effective deinking must repress the action of exoglucanase.

Purpose: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. Materials and Methods: Patients with narrow range of age (21-25. mean $22.8{\pm}1.3$, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed $21.2{\pm}7.3wks$ after trauma. Results: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight hearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). Conclusion: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.
