A 52-year-old man experienced blunt trauma upon falling from a height of 40 m while trying to repair the elevator. The patient's systolic blood pressure and hemoglobin levels were 60 mmHg and 7.0 g/dL, respectively, upon admission. A large volume of bloody discharge was observed in the open wound of the perianal area and sacrum. A computed tomography scan revealed an open comminuted sacral fracture with multiple contrast blushes. He underwent emergency laparotomy. Both internal iliac artery ligations were performed to control bleeding from the pelvis. Protective sigmoid loop colostomy was performed because of massive injury to the anal sphincters and pelvis. Pad packing was performed for a sacral open wound and perineal wound at the prone position. After resuscitation of massive transfusion, he underwent the second operation 2 days after the first operation. The pad was removed and the perineal and sacral open wounds were closed. After the damage-control surgery, he recovered safely. In this case, the hemodynamically unstable, open comminuted sacral fracture was treated safely by internal iliac artery ligation with pad packing.

Eighty-four cases of mitral commissurotomy were done in this department between October 1958 and September 1970. Therc wcre 54 males and 30 females. Six cases were under the age of 20 years. Prcoperativc embolization occurred in 9. 5% of the cases. consisting of 8. 3% cerebral and 1.2% peripheral embolization. Intraoperative and postoperative cmbolization occurred in 4.7% of the cases, with 1. 2% cerebral and 3.5% peripheral embolism. Two out of three postopeative embolism cases expired, one of which was caused by septic cerebral embolism due to valve vegetation nnd the other by mesenteric embolism. Atrial fibrillation was 1loted ill 43% of the case. Seventy closed mitral commissurotomy was done by left appendegeal approach with finger fracture method or Bailey's guillotine valvotome. Fourteen open mitral commissurotomy cases were done either by right side approach or median sternotomy, three of which were reoperation cases after blind mitral commissurotomy. One out of 14 cases were operated on with open mitral commissurotomy and concomitant open aortic valve bicuspidalization, This case expired due to severe serum hepatitis ten days after operation. Thirty-two per cent of valve calcification was noted during operation and one of which had marked vegetation on the valve cusps too. Operative mortality was 1.4% in blind mitral commissurotomy and 14% in open mitral commissurotomy. Over-all mortality in the entire series was 3.5%. One case among the blind commissurotomy cases expired during operation due to left inferior pulmonary vein laceration and death was caused in two open mitral commissurotomy cases by coronary artery airembolism. Three hospital death occurred in blind operation group, one due to coronary embolism, and two by hepatic failures. Three hospital death among open heart surgery cases were caused by hepatic failure in two and cerebral embolism in one cases. ln most of the survivors improved functional capacity and exercise lolerance were noted.

Egg development and morphological change of larvae of the Sakhalin sole Limanda sakhalinensis were studied by observing specimens obtained in a rearing experiment from fertilized eggs to the juvenile stage. The wild broodstock was collected in January 2010 and kept in a circular water tank (${\O}1.5{\times}1m$) at a temperature of $14.5{\pm}0.5^{\circ}C$. Fertilized eggs ranged from 0.72 to 0.82 mm ($0.77{\pm}0.07mm$, $mean{\pm}SD$) in diameter. The eggs were spherical, transparent and adhesive demersal. The egg yolk was divided from the oocyte 10 min after fertilization (AF), and an embryo was formed in 36 h AF. More than 50% of the eggs hatched within 133 h AF. The mouth and anus did not open until $3.5{\pm}0.25mm$ total length (TL). At 4, days after hatching (AH), the fish became larvae 3.7 to 4.2 mm ($4.0{\pm}0.36mm\;TL$), yolk absorption was completed and the mouth began to open. The left eye moved upward and the nostril moved to the right at 39 days AH. These post-larvae ranged from 8.0 to 9.9 mm TL ($8.9{\pm}1.33mm\;TL$). At 50 days AH, the fish became juveniles ($12.4{\pm}1.20mm\;TL$) There were 70-72 dorsal fin rays, 55-56 anal fin rays, 11 pectoral fin rays, and 6 ventral fin rays and the juveniles adopted a benthic life.

Because of the prominence of the nose and its central location, it is the most frequently encountered fractures in the face. Yet reports about the nasal bone fractures are virtually rare in the oral and maxillofacial surgical literatures. This is a retrospective study on 19 nasal bone fractures treated in Chosun university hospital Department of Oral & Maxillofacial Surgery from Jan. 1991 to Sep. 1993, under admission to our Dept. and the obtained results were as follows. 1. Of the 240 patients with facial bone fractures, 28 patients suffered nasal fractures(12%) and male to female ratio was 5.3:1. 2. The most frequent cause was traffic accidents(39%)m, the next fall down(36%), first blow(4%). 3. The age frequency was the highest in the fifth decade (32%). 4. Clinical classification of nasal fractures was simple fractures(74%), combined fractures(26%), and single fractures(37%), combined fractures(63%). 5. The most frequently combined site was maxilla(50%). 6. Treatments of nasal fractures were closed reduction(63%), open reduction(5%), and secondary rhinoplasty(32%). 7. The initial treatment time from accident was 1.7 days in single fractures, and 3.5 days in combined fractures, and the period of splint retained was about 8.2 days in single fracture, about 8.7 in combined fracture. 8. It was necessary to treat secondarily in delayed treatment, and all treatment methods showed relatively good prognosis. 9. Closed reduction was treated under local anesthesia, but open reduction & secondary rhinoplasty was treated under general anesthesia except 1 case. 10. The complications were disturbance of swellings 5 cases, ethetic problem 5 cases, epiphora 3 cases, abnormal sensation 6 cases in relation with other fractures.

The weekly ultrasound scanner (US) observations of reproductive organs in a commercial dairy herd with the popular stanchion style management were conducted for over 26 months. Based on reproductive records, the following were evaluated: 1) the effect of postpartum period commencement of US monitoring on herd reproductive efficacy, and 2) the effectiveness of a US monitoring-based diagnosis and subsequent treatments of reproductive disorders on postpartum reproductive efficiency. The reproductive parameters of cows, which were subjected to US monitoring between Days 30-40 (Day 0 = day of parturition), Days 41-50, Days 51-60, and above Day 61, were compared. The reproductive parameters of cows diagnosed as having reproductive disorders (RD) with US monitoring before or after the first artificial insemination (AI) were also compared. It was found that the day of commencement of US monitoring in cows diagnosed with and without RD significantly affected the period towards the first AI and the open period. In particular, cystic follicles and anoestrus detected either before or after the first AI significantly affected herd reproductive efficiency. The implementation of US monitoring improved reproductive efficiency by reducing the open period and increasing the number of milking cows in the herd. The results of this field trial indicate that the postpartum reproductive management of dairy cows with the use of the US monitoring system is one strategy to improve reproductive efficiency, especially in a high-yielding dairy herd reared stanchion management style.

Purpose: After damage control surgery, abdominal wall closure may be impossible due to increased intra-abdominal pressure (IAP), and primary closure may induce abdominal compartment syndrome. The purpose of this study was to investigate changes in the IAP and the feasibility of abdominal wall closure using artificial mesh. Methods: From July 2010 to July 2011, 8 patients with intra-abdominal hypertension underwent abdominal wall closure using artificial mesh. Medical data such as demographics, diagnosis, operation, IAP, postoperative complications, mortality and length of hospital stays were collected and reviewed, retrospectively. One patient was excluded because of inadequate measurement of the IAP. Results: Seven patients, 4 males and 3 females, were enrolled, and the mean age was 54.1 years old. Causes of operations were six traumatic abdominal injuries and one intra-abdominal infection. The IAP was reduced from $21.9{\pm}6.6mmHg$ before opening the abdomen to $15.1{\pm}7.1mmHg$ after fascial closure. Fascial closure was done on $14.9{\pm}17.5$ days after the first operation. The mean lengths of the hospital and the intensive care unit (ICU) stays were 49.6 days and 29.7 days respectively. Operations were performed $3.1{\pm}1.5$ times in all patients. Two patients expired, and one was transferred in a moribund state. Three patients suffered from complications, such as retroperitoneal abscesses, enterocutaneous fistulas, and bleeding that was related to the negative pressure wound therapy. Conclusion: After abdominal wall closure using artificial mesh, intra-abdominal pressure was well controlled, and abdominal compartment syndrome does not occur. When the abdominal wall in patients who have intra-abdominal hypertension is closed, artificial mesh may be useful for maintaining a lower abdominal pressure. However, when negative pressure wound therapy is used, the possibility of serious complications must be kept in mind.

This study was implemented to verify the feasibility of motor function recovery and the appropriate period for therapy. The research began with spinal laminectomy of 40 white rats of Sprague-Dawley breed and induced them spinal crush injury. Following results were obtained by using the modified Tarlov test (MTT), Basso, Beattle, Bresnahan locomotor rating scale (EBB scale) and modified inclined plate test (MIPT). First, the measurement using the MTT confirm that the most severe aggravation and degeneration of functions are observed two days after induced injury, and no sign of neuromotor function recovery. Second, better scores were achieved by open-ground movement group on BBB locomotor rating scale test, and weight-bearing on inclined plate group show better performance on MIPT. Third, both BBB and MIPT scale manifested the peak of motor function recovery during 16th day after the injury and turn into gradual recovery gradient during 16th to 24th. Fourth, the control group showed functional recovery, however, the level of recovery was less significant when compared with group open-ground movement group and weight-bearing on inclined plate group. Hence, it was clearly manifested that the lumbar region of the spinal cord had shown the best performance when its functions were measured after the execution of specific physical training; therefore it indicated the possibility of learning specific task even in damaged lumbar regions. Thus it is expected to come out with better and more effective functional recovery if concentrated physical therapy was applied starting 4 days after the injury till 16 days, which is the period of the most active recovery.

Background: Inhaled nitric oxide therapy causes selective pulmonary vasodilation in congenital heart diseases with pulmonary hypertension. However discontinuation of inhaled nitric oxide therapy may be complicated by abrupt life-threatening rebound pulmonary hypertension(RPH) The purpose of this study was to prevent by comparing group I(without RPH n=13) and group II(with RPH n=6) to determine the risk factors involved inthe development of the RPH. Material and Method: Between Januarty 6, 1998 and April 14, 1999. we studied 19 consecutive children who were treated with inhaled nitric oxide for clinically significant pulmonary hypertension after an open heart surgery for congenital heart disease. the ratio of males and females was 12:7 ranging in age from 10 days to 6040 days(16 years) To identify the effects of nitric oxide between two groups we measured heart rate mean and systolic pulmonary arterial pressure mean and systolic systemic arterial pressure central venous pressure pH paO2/FiO2 and O2 saturation before and after the initiation and just before the withdrawal of the inhaled nitric oxide. result: In 6 of 19 patients(32%) withdrawal of inhaled nitric oxide caused RPH. In the two groups inhaled nitrix oxide decreased in pulmonary arterial pressure(PAP) without decreasing the systemic arterial pressure(SAP) and increased PaO2/FiO2 Compared with patients who had no RPH(group I) patients who had RPH(group II) were older in age (1204$\pm$1688 versus 546$\pm$1654 days p<0.05) received less nitric oxide therapy(34$\pm$18 versus 67$\pm$46 hours p<0.05) has shorter weaning process(5$\pm$3 versus 15一13 hours p<0.05) and received lowerconcentration of initial nitric oxide supply(11$\pm$8 versus 17$\pm$8 ppm p>0.05) and lower concentration just before the withdrawal nitric oxide(4.2$\pm$2.6 versus 5.6$\pm$2.6 ppm, p>0.05) Conclusion : We speculate that older age shorter of nitric oxide therapy shorter weaning process are the risk factors of RPH.

The stability of the genetically engineered microorganisms and their recombinant plasmids released in natural environments has been regarded as one of the molecular ecological topics. In this study, the recombinant plasmids pCU103 in which the pcbCD genes involved in biodegradation of biphenyl and 4-chlorobiphenyl were cloned in pBluescript SK(+) vector, were examined for their structural and functional stability in different waters at 15 $^{\circ}C$ by the methods of electrophoresis, Southern hybridization, quantification with fluorescent dye, and transformation. The recombinant plamids maintained their stabilities for about 30 days in sterilized distilled water (SDW), 15 days in autoclaved creek water (AW), 25 days in filtered and autoclaved non-sterile creek water (FAW), 4 days in Luria-Bertani (LB) broth, and less than one day in filtered non-sterile creek water (FW). The covalently closed circular (CCC) form of the plasmid was decreased and open circular (OC) form was increased as a function of incubation time, and then linear (L) form was produced to be ultimately degraded out. The degradation rates of the plasmid were proportionally correlated to trophic level of the water, and the biological factor such as DNases was found to be one of the most critical factors affecting structural and functional stability of the plasmid in non-sterile natural water.
