<P>PURPOSE: To evaluate the efficacy and safety of single-session OK-432 sclerotherapy for the treatment of renal cysts. MATERIALS AND METHODS: From October 2005 to November 2006, 48 patients (61 simple renal cysts) were included in the study. Indications were determined as flank discomfort (n = 37) or patient reassurance due to increasing size (n = 11). The simple renal cysts were aspirated under ultrasonography (US), at which point OK-432 was injected into the cyst. Follow-up was performed with US or computed tomography scan every 3 months until 1 year. Complete regression of the renal cyst or more than 70% reduction in size with no symptoms indicated a successful treatment. RESULTS: Among 61 renal cysts of 48 patients, the overall success rate was 98.4%. Complete regression occurred in 46 cysts (75.4%), and more than 90% reduction in size occurred in 6 cysts (9.8%). A size reduction of 80% to 90% and 70% to 80% occurred in five (8.2%) and three cysts (4.9%), respectively. A size reduction less than 70% occurred in only one cyst (1.6%). The success of cyst regression was correlated with cyst volume. Clinical symptoms resolved in 100% of patients with symptomatic cysts, and there was no enlargement of the aspirated cysts at the 1-year follow-up. After the procedure, there were only some minor complications, such as mild fever, flank pain, and leukocytosis, which subsided with the conservative treatment. CONCLUSIONS: Percutaneous OK-432 sclerotherapy is simple, safe, and effective, and it can be an alternative first-line therapy for simple renal cysts.</P>

This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

The excessive initial corrosion rate of Mg is a critical limitation in the clinical application of biodegradable Mg implantsbecause the device loses its fi xation strength before the fractured bone heals. This study suggests a new approach to overcomethis hurdle by accelerating tissue regeneration instead of delaying the implant biodegradation. As angiogenesis is anessential process in early bone regeneration, a Mg implant coated with electrospun nanofi bers containing nitric oxide (NO),which physiologically promotes angiogenesis, is designed. The integrated device enables adjustable amounts of NO to bestored on the NO donor-conjugated nanofi ber coating, stably delivered, and released to the fractured bone tissue near theimplanted sites. An in vitro corrosion test reveals no adverse eff ect of the released NO on the corrosion behavior of the Mgimplant. Simultaneously, the optimal concentration level of NO released from the implant signifi cantly enhances tube networkformation of human umbilical vein endothelial cells without any cytotoxicity problem. This indicates that angiogenesis canbe accelerated by combining NO-releasing nanofi bers with a Mg implant. With its proven feasibility, the proposed approachcould be a novel solution for the initial stability problem of biodegradable Mg implants, leading to successful bone fi xation.

The purpose of this study was to investigate how to express wearing style through characters and images of dramatis personae based on 「La Traviata」s played by 3 different directors : Mario Lanfranchi's performance, Franco Zeffirelli's performance and Richard Eyre's performance, with actual approach and costume expression of Opera by considering expressional characteristics of wearing style on Stage costume. First, stage costumes of each performance have the common expressional characteristics ; Silhouette shows historical setting, material and color shows characters and images of dramatis personae, details and trimming to make images more effective express characteristics ·social class ·personality ·images of the cast. As the plot progresses, main subject and atmosphere are expressed with darker color. It brings catastrophe. That means that even if each performance has been made in different year and by different director, whole atmosphere, color and materials of all stage costumes are closely similar. Second, stage costumes of the Opera has a tendency to be simplified around the late 20 century. Works of the middle 20 century use gay details and excessive trimming while works of the late 20 century use silhouette to express the historial setting and use the simple design but detail and trimming. Third, the recent stage costumes emphasize simple wearing style and symbolic representation of the cast including historical circumstances. That means unique clothes, stage costumes, follows simple and functional trend of daily dress. As the stage costume applies the popular trend, costumes style is getting simplified and adornment is getting disappeared. Modernism of the late 1900's might effect this trend. As conclusion, stage costume expression of Opera shows the current and the background which the symbol applies to and expresses characteristics of the cast. The stage costume plays a symbolic role in delivering the plot like dumb lines of Opera. That is, stage costume of composite art, Opera, plays a very important role as one of visual factors to elevate the atmosphere

Cooling is therefore normally achieved through a balance of rant and fan action. Coolant is used to cool the engine's radiator and turbocharger intercooler in order to provide suitable temperatures, which result in higher power, better fuel economy, improved emissions and extended engine life. There are a variety of cooling systems that can be used to accomplish this goal. More recently additional large heat loads hate been imposed and fan site had to be increased. To reduce the associated increase in noise and to achieve a better match for engine-drive fans between the cooling air flow under ram conditions and the heat load generated by the engine, various means were devised to modulate the fan's output, or to decouple th e fan from the engine. Present emphasis on improved fuel economy has created a new urgency to make cooling systems more compact and efficient. This paper studies the various conditions and analyze the heat exchanger's capabilities and cooling effectiveness for several air flowrates, based on a typical automotive engine.

쇄골두개 이형성증은 골격과 치아 이상을 동반하는 선천성 질환으로서 다수의 조직과 장기에 직접적인 영향을 주는 중배엽성 기능장애이다. 쇄골두개 이형성증에서 일반적인 골격 결함은 두개 봉합과 천문의 지연 폐쇄, wormian bone, clavicle aplasia가 나타날 수 있다. 또한 장골, 지골, 척추, 골반 등의 전체 골격 뿐 아니라 근육, 중앙 신경계 등에 영향을 줄 수 있다. 구강내 특징으로 유치의 만기잔존, 다수의 과잉치, 미맹출된 영구치, 낭 형성 등이 나타난다. 그러나 쇄골두개 이형성증 환아의 경우 정신적 및 신체적으로 특별한 이상을 나타내지 않아 스스로 질환을 인식하지 못하는 경우가 많으며 이의 결과 유치 탈락 후 영구치의 미맹출로 인하여 저작 및 심리적인 문제가 초래되는 경우가 많다. 따라서 쇄골두개 이형성증은 조기진단이 필요하며, 적절한 시기에 과잉치 제거 및 영구치 맹출을 유도하는 치료를 시행하여 저작기능의 회복 뿐 아니라 환자의 안모도 개선시킬 수 있어야 한다. Cleidocranial dysplasia(CCD) is a congenital disorder of skeletal and dental abnormality, which is mesodermal dysfunction influencing many tissues and organs. Skeletal abnormalities in CCD are delayed closure of cranial suture and fontanelle, presence of wormian bone and clavicle aplasia. And CCD has an effect on the long bones, phalanges, spine, pelvis, muscles, and central nervous system. Dental manifestations include retention of deciduous teeth, multiple supernumerary teeth and formation of cysts around nonerupted teeth. But as a result in common with a lack of medical and physical disability, patient may have no substantive complaint, there are many masticatory and psychological problem by absent eruption of permanent teeth after exfoliation of deciduous teeth. For this reason CCD is necessary fo early diagnosis and must be improvement of the patient's appearance as well as provision of a functioning masticatory mechanism by treatment of surgical removal of supernumerary teeth, followed orthodontically eruption of the natural permanent teeth at adequate time.
