Objectives : This report intended to estimate effects of Jung-an acupuncture on the acquired torticollis caused by muscle contraction. Methods : The patients were treated by Jung-an acupuncture, herb medication and Physical treatment daily. The improvement of the patients was judged by Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS), Tsui's score and Visual Analogue Scale(VAS). Results : After 7 days of treatment, the 2 patients' neck pain and cervical movement were improved. Also, TWSTRS score, Tsui's score and VAS were all reduced. Conclusions : As the Jung-an acupuncture's theological base is organized with meridian theory and myofacial release therapy, We considered the Jung-an acupuncture is effective not only for the skin disease but also for the muscle problem such as torticollis.

Correlation Between Primary Si and Silicide Refinement Induced by Ultrasonic Treatment of Multicomponent Al–Si Alloy Containing Ti, Zr, V, and P

The correlation between primary Si and silicide refinement induced by ultrasonic treatment (UST) of multicomponent Al–Sialloy containing Ti, Zr, V, and P was investigated. UST significantly refined the primary Si phase owing to cavitation-inducedwetting and deagglomeration of MgAl2O4particles. Lowering the UST finish temperature caused deterioration of the degreeof primary Si refinement, instead leading to silicide refinement. Cavitation-induced silicide nucleation on wetted MgAl2O4consumed the MgAl2O4particles, particularly in the case of primary Si nucleation. Similarly, the formation of an AlP phaseon the silicide phase reduced the nucleation efficiency of the AlP phase. Poisoning of the MgAl2O4and AlP phases by thesilicide phase was responsible for the deterioration in primary Si refinement. Room-temperature tensile strength and hightemperatureelongation were increased by UST and were dependent on the size of primary Si.

정영정,김영재,김정욱,장기택 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.2

하악 견치의 매복은 흔하지 않으며, 특히 정중선을 지나서 전위 매복되는 경우는 매우 드물다. 매복 견치의 처치는 장애물의 존재 여부와 매복 위치와 방향, 맹출 가능한 공간의 유무, 치근의 형성 간계에 따라, 맹출 장애 요인을 제거한 후의 주기적 관찰 및 외과적 노출과 교정적 견인, 치아 이식, 외과적 발치 둥의 방법으로 이루어진다. 본 두 증례 중 치아종과 함치성 낭종을 동반한 매복 견치를 갖는 환아에서 외과적 노출과 교정적 견인을 시행하였고, 함치성 낭종과 과잉치에 의해 매복된 하악 견치를 갖는 환아에서는 견치가 친위 매복된 상태로, 교정적 견인이 어렵다고 판단되어 자가 이식 후 근관 치료와 교정 치료를 시행하였다. Impaction of mandibular canine is not common, and transmigration of mandibular canine is rare. Treatment of impacted canine can be removal of physical obstacle and periodic observation, surgical exposure of impacted tooth and orthodontic traction, autotransplantation, surgical extraction. Management of impacted canine depends on existence of physical obstacle, position and direction of impacted tooth, space available for canine eruption, stage of root development. Of the two case in this report, one case involved impaction of lower canine with odontoma and dentigerous cyst that is treated by surgical exposure and orthodontic traction. The other case involved transmigration of lower canine with supernumerary teeth. It was thought difficult to treat only by orthodontic treatment; so the impacted canine was transplanted to its normal position and orthodontic treatment was conducted.

정영정,현홍근,김영재,김정욱,이상훈,김종철,한세현,장기택 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.2

상아질-레진 접착강도에 대한 collagenase와 esterase의 영향을 살펴보기 위해, 소구치의 교합면 상아질에 Single Bond 2와 Clearfil SE Bond로 접착을 시행하고 미세 시편을 제작하여 PBS, collagenase 용액, esterase 용액에 4주간 보관한 후 미세인장결합강도를 측정, 비교하여 다음과 같은 결론을 얻었다. 1. 모든 보관 용액에서 Single Bond 2의 미세인장결합강도는 Clearfil SE Bond보다 유의하게 낮았다(p<0.05). 2. Single Bond 2의 미세인장결합강도는 collagenase군이 PBS군, esterase군보다 낮았다(p>0.05). 3. Clearfil SE Bond의 미세인장결합강도는 esterase군이 PBS군에 비해 낮았으나(p>0.05), collagenase군보다는 높았다(p>0.05). Collagenase군은 PBS군에 비해 유의하게 낮은 미세인장결합강도를 보였다(p<0.05). The purpose of this study was to evaluate the effect of collagenase and esterase on the microtensile bond strength (μTBS) in dentin bonding. After resin composites were bonded to occlusal dentin, μTBS specimens were formed and stored in PBS, collagenase, or esterase solution. After 4-week storage, μTBS was determined and, the results were as follows: 1. μTBS values of Single Bond 2 were lower than those of Clearfil SE Bond for all storage medium (p<0.05). 2. In single Bond 2 group, collagenase solution lowered bond strength more than PBS and esterase solution (p>0.05). 3. In Clearfil SE Bond group, esterase solution lowered bond strength more than PBS(p>0.05). Collagenase solution lowered bond strength more than esterase solution(p>0.05) and PBS(p<0.05).

기관지성 방선균증은 매우 예외적이고 드물며 임상양상이 다양하여 폐암과의 감별이 어렵기도 하지만 기관지내시경 검사를 통해 진단할 수 있고 항생제 투여로 완치될 수 있는 질환이다. 저자들은 기관지석과 함께 발현한 기관지성 방선균증을 장기간의 경구 항생제 요법으로 완치한 1례를 경험하였기에 보고하는 바이다. Endobronchial actmomycosis is considered as an exceptional event. We report a case of a 49-year-old woman who presented with cough and exertional dyspnea for 20 months. Her chest X-ray showed calcified lymph nodes in the right lower paratracheal and subcarinal area and consolidation in the right middle lobe. Bronchoscopic examination demonstrated whitish broncholithiasis with mucosal nodularity in the bronchus intermedius obstructing the lumen near-completely. The biopsy specimen revealed sulfur granules and calcified material which were consistent with actmomycosis. Prolonged oral antibiotic treatment resulted in complete recovery, without need for surgical resection.

정영정,김연재,김정욱,이상훈,김종철,한세현,장기택 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.1

최근에 개발된 나노 충전제를 microhybrid 복합레진에 첨가할 때, 나노 충전제 함량이 중합에 미치는 영향을 조사하기 위해, 실험적으로 나노 충전제의 함량을 다르게 제작한 복합레진에서 광중합 후 미세경도를 측정, 분석하여 다음과 같은 결론을 얻었다. 1. 나노 충전제의 함량이 2%, 3%인 군은 0%, 1%인 군에 비해 중합된 면의 미세경도가 유의하게 높았으나(p<0.01), 그 차이는 크지 않았다. 2. 나노 충전제의 함량이 높을수록 레진 시편의 하면에서의 미세경도는 증가하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). 3. 레진 시편의 상면과 하면의 미세 경도 차이는 나노 충전제 함량이 높을수록 감소하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). The objective of this study was to evaluate the effects of nanofiller content on the microhardness and polymerization of experimental microhybrid composites. The nanofiller contents in the experimental composites were varied (0%, 1%, 2%, 3%), while the total filler content remained constant as 76 %wt. We obtained the following results: 1. The microhardness of the top surface for the 2%, 3% nanofilled microhybrid composites were significantly higher than those for the 0%, 1% nanofilled composites (p<0.05), but the difference was not great. 2. The microhardness of the bottom surfaces significantly increased with an increase in the nanofiller level (p<0.05), except between the 2% and 3% nanofilled groups (p>0.05). 3. As the nanofiller level increased, the difference beween microhardness of top and bottom surfaces significantly decreased (p<0.05), except between 2% and 3% nanofilled groups (p>0.05).

Coronary artery anomalies are found incidentally in approximately 1% of all patients undergoing routine coronary angiography. Of these, an isolated single coronary artery anomaly is the rarest one. Patients with an isolated single coronary anomaly may present with symptoms such as angina pectoris, myocardial infarction, arrhythmias, syncope, sudden death, and congestive heart failure. We report a case of single coronary artery anomaly with the left anterior descending and left circumflex coronary artery originating from the right coronary artery.
