In this study, mortality, body wet weight, health assessment, and short-term behavioral mode were observed to determine the effects of ultrasound on the ecological response of the carp Cyprinus carpio. Mortality in the treatments was less than 5% during ultrasound exposure (31 dB re 1 ${\mu}Pa$, $14{\sim}15$ kHz) and there were no significant differences among the replicates (P>0.05). The treatments, based on mean wet weight, exhibited greater effect than the controls, but the magnitude of the differences was not large. Skins and tail fins of some test animals exposed to the controls and intensive treatment groups had light injury such as hemorrhaging, whereas, damages in other organs such as eyes, other fins, parasites, thymus, and gills were not observed (P>0.05). Sudden stimuli in low intensity at a short distance caused a directional avoidance of the fish from the sound. However, the carp exposed to ultrasound at the large scale field was not observed clear behavior changes. Overall results suggest that fish exposed to the low-intensity ultrasound had no serious stress during the tests.

Background: The aim of the current study was to analyze the early and intermediate-term performance of aortic valve replacement. Material and Method: Between January 1986 and January 1996, records of 61 consecutive patients who had received aortic valve replacement were reviewed. 38 were male and 23 were female patients, ranging from 10 to 71 years of age(mean: 40.5${\pm}$11.2). Results: The early death rate was 4.9%(3/61). A thorough follow-up rate of 93.1% was accomplished in these 58 patients who left the hospital(mean: 51.5${\pm}$32.0 patient-months) under the assistance of the same operator. Three of these patients who left the hospital died. The late death rate was 5.2%(3/58). Five patients experienced anticoagulant-related hemorrhage(all were minor). Three patients had thromboembolic episodes. There was no clinical evidence of hemolysis and structural failure of valves used. Of those patients who survived, the NYHA functional class improved significantly. Linearized rate were 1.58%/patient-year and 2.0%/patient-year respectively for thromboembolism and anticoagulant-related hemorrhage. The 10 year actuarial survival rate was 83.6%. Conclusion: This early and intermediate-term follow-up suggests that the mechanical valve is a reliable and durable prosthesis with good hemodynamic function and low rate of prosthesis-related complication.

Purpose : To validate the arthroscopic synovectomy for the treatment of hemophilic knee. Materials and Methods: From January 1996 to January 2001, 28 arthroscopic synovectolny were performed in 26 patients with hemophilic arthropathy of the knee. The mean age was 17.8 years. The mean follow-up period was 3 years 11 months. We used six portals (two anterior, two suprapatellar and two posterior) and posterior trans-septal portal in all cases. Result : The mean frequency of hemarthrosis was 4 times per month preoperatively and 2 postoperatively. The mean amount of factor replacement was 4,633 units preoperatively and 1,505 postoperatively. The mean range of motion was $112^{\circ}$ preoperatively and $107^{\circ}$ postoperatively. On radiographic evaluation, three cases were progressed at the latest follow-up. On the subjective evaluation, significant or moderate improvement were in 19 cases $(68\%)$, and no improvement or deterioration in 9 cases $(32\%)$. Conclusion : With complete synovectomy through the appropriate arthroscopic portals, arthroscopic synovectomy of the knee in hemophilic patients is the successful method in decreasing bleeding episodes, amount of factor replacement, knee pain and preventing or delaying onset of end-stage hemophilic arthropathy.

The purpose of this study was to investigate the prevalence of dental caries, periodontal status, and self-perceived oral health status of students in juvenile protection education institutions. The subjects of this study were 342 adolescents aged 13-20 years detained in two juvenile protection education institutions located in Gyeonggi Province. The study involved an oral examination to record decayed, missing, filled teeth and index teeth with bleeding, calculus, or periodontal pocket, combined with a questionnaire to investigate self-perceived oral health status. The main findings are as follows. 1. When compared with the result of National oral health survey, the students detained had more decayed teeth, DMFT, and teeth with bleeding, calculus, and shallow pocket than general population of the same age. 2. Female students showed more DMFT, more teeth with healthy periodontium, and fewer teeth with shallow pocket than male students (p<0.05). 3. Female students perceived their health to be poorer than male students (p<0.05). A majority(79.2%) of detainee valued their oral health in their life. 4. A majority(71.5%) of detainee reported their dental anxiety, and more female adolescents showed dental anxiety than male adolescents(p<0.05).

Aortic aneurysm has poor prognosis and high mortality, but the incidence of aortic aneurysm is in increasing state. From July, 1986 to July, 1996, we operated on 25 patients with aortic aneurysm and analysed the clinical results and relations between the duration from symptoms onset to operation(Sx-Op), the duration from admission to operation(Adm-Op), preoperative blood pressure, preoperative heart rate and postoperative mortality, retrospectively. The patients were classified as dissecting aneurysm(10 cases), abdominal aortic aneurysm(9 cases), Marfan's syndrome(3 cases), descending thoracic aortic aneurysm(3 cases). The operative technique were graft interposition in 17 cases, Bentall's operation in 4 cases, aneurysm bypass in 2 cases, and wrapping of aorta in 2 cases. Seven patients died of several causes, bleeding in 5 cases, acute renal failure in 1 case and respiratory failure in another one case. Before 1992, the early stage of operation, 6 mortality among 14 operated patients occurred, and after then 1 mortality among 11 operated patients occurred. Eighteen survivors were followed up from 1 to 118 months(mean 50.6 months), and total follow up was 911 patient-months. During the follow up period one patient died of melena 30 months after operation. The other patients did not complain chest pain or dyspnea. The surgical mortality was improved in the late period, and the major cause of death was intraoperative or postoperative bleeding. The Sx-Op duration, the Adm-Op duration, preoperative blood pressure and preoperative heart rate were proven to have no statistical relations with postoperative mortality.

Thrombolytic therapy with tissue plasminogen activator (tPA) can improve the clinical outcome of ischemic stroke patients. However, its clinical application is limited by narrow therapeutic time windows and elevated risks of cerebral hemorrhage and brain injury. In part, these effects of tPA has been related to matrix metalloproteinase-9 (MMP-9) dysregulation. Here, we investigate that the effects of alteplase (tPA with short half-life) and pamiteplase (a modified tPA with long half-life) on the MMP-9 regulation in neurovascualr unit. The total levels of MMP-2 and MMP-9 in neuronal cells are lower than astrocytes. Alteplase (1-10 ${\mu}g/ml$) induced upregulation of MMP-2 and MMP-9 in rat cortical neurons and astrocytes, respectively. Whereas pamiteplase in a wide range of dose did not affect the MMP-2 and MMP-9 responses in both of cells. These results suggest that pamiteplase with long half-life can be provided as a agent that overcome the side effects of alteplase.

From March 1, 2016 to August 31, 2016, 375 dental implant patients between the ages of 30 and 70 years to evaluate their subjective symptoms and satisfaction according to prosthesis methods. The collected data were analyzed using the chi-square distribution test, t-test, one-way analysis of variance, and multiple logistic regression. Of the patients with subjective symptoms of peri-implantitis, 40.5% reported food impaction, 49.1% reported bleeding, 61.1% reported pain, 61.9% reported halitosis, and the overall satisfaction level with the implants was 3.95 points. In the prosthesis methods, implant-teeth connective group showed the lowest level of the food impaction (21.3%), the pain (35.5%), and the halitosis (36.6%) (p<0.001), and the lowest bleeding was the implant single (33.8%) (p<0.05). Patient satisfaction was higher in the implant-teeth connective group (4.06 points) and the group without bone grafting (4.03 points) (p<0.01). Factor analysis showed that implant satisfaction was 0.43 times lower in the single implant group and 0.44 times lower in the implant-implant connective group than in the implant-teeth connective group. As a result of the study, it is expected that the method of extending the life of adjacent teeth and restoring the function of the tooth defect region is an implant-teeth connection method, so that it can be utilized positively through various clinical studies.
