The objective of this study was to assess the complications of titanium clip application after ovariohysterectomy (OHE) and find the proper surgical technique to minimize the complications by comparing the ligation method of ovarian pedicle. Six female beagle dogs were used for this study and they were divided randomly into two groups by ligation techniques: ligation and non-ligation of the suspensory ligament of ovary including ovarian pedicle. To evaluate the difference between two techniques, the location and embedded pattern of applied clips in the abdominal cavity were identified through radiographic tests and autopsy. Hematology tests were also performed to check the existence of inflammation by applied clips and all tests were carried out monthly for 1 year. There were few changes in location of clips of both groups on X-ray views without any migration. Almost all values in hematology of two groups were within the normal range and there were no inflammatory symptoms. All of applied clips in two groups were found near the kidney, but the embedded forms of them showed slight differences. The clips ligating suspensory ligament and ovarian pedicle were located in deep place and thickly surrounded with thin layers of peritoneum. But the clips ligating only ovarian pedicle were found with ease on surface of layer and located in lower place compared with the clips ligating suspensory ligament. These results indicate that the suspensory ligament holds applied clips and minimizes the movement of them. Therefore, ligation of suspensory ligament would be the preferred technique in titanium clip application for OHE.

Although traumatic thoracic aortic rupture is potentially a fatal condition requiring surgical attention, the presence of concomitant injury involving other parts of the body may greatly increase the risk of cardio-pulmonary bypass. We report our experience of treating associated injuries prior to the thoracic aortic rupture in these patients. Material and Method: From 1997 to 2003, the medical records of 24 traumatic aortic rupture patients were retrospectively reviewed and checked for the presence of associated injury, surgical method, postoperative course, and complications. Surgical technique comprised thoracotomy with proximal anastomosis under deep hypothermic circulatory arrest followed by side arm perfusion to reestablish cerebral circulation. CSF drainage was performed to prevent lower extremity paraplegia. Result： Major concomitant injuries (n=83) were noted in all of the reviewed patients, Of these, there were 49 thoracic injuries, 18 musculoskeletal injuries, and 13 abdominal injuries, Operations for associated injuries (n=16) were performed in 12 patients on mean 7.6$\pm$12.6 days following the injury. The diagnosis of aortic rupture at the time of injury was detected in only 18 patients. Delayed surgery of the thoracic aorta was performed on average 695$\pm$1350 days after injury and there were no deaths or progression of rupture in any of these patients during the observation period. There were no operative deaths and no major postoperative complications. Conclusion: Treating concomitant major injuries prior to the aortic injury in traumatic aortic rupture may reduce surgical mortality and morbidity.

The purpose of this study was to evaluate the effects of education and test information provision on anxiety, discomfort, and satisfaction of patients during double contrast barium enema. The experiments were conducted from October 11, 2010 to November 5, 2010. Among all patients who visited the hospital to receive colon study in the outpatient radiology clinic of one general hospital located in Seoul, a total of 50 patients fit for selection criteria were divided into an experimental group (25) and a control group (25). After providing education and test information to the experimental group, we evaluated patients' levels of anxiety and discomfort, as well as satisfaction. The experimental group and the control group had different anxiety scores: 3.76 versus 6.04 respectively (P<0.05). In addition, the levels of abdominal pain and anal pain in the experimental group were lower than those of the control group (P<0.05). Lastly, the scores of test satisfaction between two groups were 89.6 and 67.4 respectively (P<0.05). Education and test information provision about the colon study decreased the levels of patients' anxiety and discomfort and increased satisfaction level of the test.

The present study furthered this research by determining the optimal level of inuloprebiotics derived from Korean Jerusalem artichoke to promote growth in broiler chickens. On hatch day, 320 male Ross 308 broilers were randomly allotted to four groups for a 35-day feeding regimen. The groups were a control (no supplementation), diet supplementation with antibiotics (8 ppm avilamycin), supplementation with 200 ppm inuloprebiotics, and supplementation with 250 ppm inuloprebiotics. Body weight and feed intake were comparably high in the two inuloprebiotics groups, and exceeded the values for the control and antibiotics groups. Body weight and feed intake was higher in chickens fed the antibiotics supplemented diet, compared to controls. There were significant differences among treatment groups. Feed conversion ratio during total experimental periods was significantly high in the control group compared to the inuloprebiotics-fed groups, but no significant difference was evident using antibiotics or inuloprebiotics dietary supplementation. Carcass weight, dressing percentage, and weight of breast and thigh muscle were significantly higher for inuloprebiotics-fed chickens, compared with control and antibiotic-fed chickens. Inuloprebiotics concentration was not significant, while antibiotics-fed chickens displayed significantly higher values than control chickens. Abdominal fat was significantly reduced (19.08%-23.30%) and blood immunoglobulin and the weight of the thymus and Bursa of Fabricius were significantly increased in chickens receiving inuloprebiotics-supplemented feed, compared to control and antibiotics fed groups. In the lower intestine, the viable counts of beneficial bacteria (Bifidobacteria and Lactobacillus) were significantly increased and counts of harmful bacteria (Escherichia coli and Salmonella sp.) were significantly decreased in the presence of the inuloprebiotics, compared to control and antibiotic. The present results support 200 ppm as an optimal level of Korean Jerusalem artichoke-derived inuloprebiotics as a dietary supplement to improve growth in broiler chickens.

Purpose: Bicycle riding is an increasingly popular sports and leisure activity in Korea. The aim of this study was to identify injury patterns of admitted patients who were injured from bicycle riding. Materials and Methods: This study examined 71 patients from Jan. 2008 to May 2009. There were 54 male and 17 female patients. We investigated the injured body parts, mechanisms of injury, location of injury, types of bicycles, purpose of bicycle riding, any concomitant luggage or passenger on rear seat, injury seasons and the helmet use. We analyzed the data using Injury Severity Score(ISS). Results: There were 11 cases of ISS 1, 41 cases of ISS 4, 2 cases of ISS 5, 13 cases of ISS 9, one case of ISS 13, two cases of ISS 16 and one case of ISS 29 among the 71 patients. 36 patients(50.7%) underwent surgery for upper and lower extremity injuries, two patients for vertebral body fractures, 8 patients for facial bone injuries and one patient for abdominal organ injury. There were 10 head injuries among whom three patients received treatment in ICU(4.2%). Conclusion: Bicycle riding can cause severe injuries with subsequent admission and major surgeries. Several measures including constructing more bicycle road, public campaign and wearing protective gears should be instituted.

Empyema necessitatis refers to empyema that extends into the extrapleural space through a defect in the pleural surface. Tuberculous empyema necessitatis is a rare complication of tuberculosis. We experienced a 21-month-old boy with tuberculous empyema necessitatis with osteomyelitis in the right $7^{th}$ rib. He presented with a mass on the right lateral chest wall, which was soft and nontender, enlarging for one month. He also had mild fever. The plain radiograph of his chest revealed soft tissue swelling and calcified lymph node on the left axilla, and his PPD skin test was positive. CT scan of the chest showed empyema necessitatis at the right lower chest and upper abdominal walls with osteomyelitis of the right $7^{th}$ rib. He did not have concurrent pulmonary tuberculosis. Surgery was performed for diagnosis and treatment. In histopathologic findings, chronic granulomatous inflammation with caseation necrosis was shown and was positive for acid fast bacilli stain. In addition, M. tuberculosis complex was found as etiology by polymerase chain reaction. The patient has been treated with anti-tuberculous medication without any specific complication.

This study was conducted to evaluate extruded pellet (EP) diet compared with a raw fish moist pellet (MP) diet for flounder, Paralichthys olivaceus on field feeding experiments in Jeju area. The experimental EP diet (juvenile, growing and adult) was prepared based on the former studies on nutrient requirements and feed ingredient of flounder. Fish were distributed randomly to each aquarium as a group of 102,300 fish (initial mean weight 97 g) in field experiment I and reared randomly to each aquarium as a group of 40,000 fish (initial mean weight 120 g) in field experiment II. In field feeding experiment I conducted in commercial flounder farm, survival, wt. gain (94-1,090 g), feed efficiency and condition factor of fish fed experimental EP were comparable to those of fish fed MP, but considerably higher protein efficiency ratio were observed in fish fed experimental EP. In field feeding experiment II, no significant difference was observed in final mean weight of fish fed the experimental EP (1,234 g) and MP (1,286 g), and any noticeable problem caused by feeding the experimental EP was not found during the whole period of feeding trial. Survival of fish fed the experimental EP was lower than that of MP, and there was no significant difference in feed efficiency between the fish fed experimental EP and MP. Therefore, these results strongly suggest that diet EP could be developed to replace MP diet for the marketable size (1.3 kg) of production for flounder without adverse effects on growth performance. In particular, abdominal dropsy and reduction of condition factor, which are frequently occurred in commercial EP feeding farms, were not observed in flounder fed experimental EP.

Magnolia obovata exhibit several beneficial effects including anti-oxidant effects. Magnolia obovata is used as a therapeutic agent to stop hemorrhages and a tonic to promoted health in Korean and Chinese medicine. The pharmacokinetic profiles of the main Magnolia obovata is still not accurately investigated. In present study, I examined the effects of water extracts of Magnolia obovata on atherosclerosis induced high cholesterol diet in rats in serum and abdominal aorta. A total of 3-week old 9 male rats of Sprague-Dawley were divided into 3 groups and fed with the basal diet (normal group), high cholesterol diet (atherosclerosis induced group) for 8 weeks, high cholesterol diet supplemented with water extracts of Magnolia obovata (Magnolia obovata group) for 2 weeks. And rats were sacrificed, serum lipid level, abodominal aortic anti-oxidant activities and lipid peroxide were measured. These results indicated that serum total cholesterol, LDL-cholesterol, triglycerides concentration significantly lower in Magnolia obovata group than high cholesterol diet group. But HDL-cholesterol concentration had significantly higher in Magnolia obovata group than high cholesterol diet group. In conclusion, Magnolia obovata controls of lipid level of hyperlipidemia and hypercholesterolemia, thus suppresses the proliferation of intima in endothelial cells, which is risk factors of atherosclerosis induced high cholesterol diet in rats. I consider as Magnolia obovata is worth to using as atherosclerosis treatment.

Purpose : To describe how a robust implementation of a radial 3D gradient-echo sequence with stack-of-stars sampling can be achieved, to review the imaging properties of radial acquisitions, and to share the experience from more than 5000 clinical patient scans. Materials and Methods: A radial stack-of-stars sequence was implemented and installed on 9 clinical MR systems operating at 1.5 and 3 Tesla. Protocols were designed for various applications in which motion artifacts frequently pose a problem with conventional Cartesian techniques. Radial scans were added to routine examinations without selection of specific patient cohorts. Results: Radial acquisitions show significantly lower sensitivity to motion and allow examinations during free breathing. Elimination of breath-holding reduces failure rates for non-compliant patients and enables imaging at higher resolution. Residual artifacts appear as streaks, which are easy to identify and rarely obscure diagnostic information. The improved robustness comes at the expense of longer scan durations, the requirement for fat suppression, and the nonexistence of a time-to-center value. Care needs to be taken during the configuration of receive coils. Conclusion: Routine clinical use of radial stack-of-stars sequences is feasible with current MR systems and may serve as substitute for conventional fat-suppressed T1-weighted protocols in applications where motion is likely to degrade the image quality.
