BACKGROUND: The positive effects of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) and minocycline on ischemic stroke models have been well described through numerous studies. The aim of this study was to evaluate the effectiveness of combination therapy of hBM-MSCs with minocycline in a middle cerebral artery occlusion rat model. METHODS: Forty male Sprague-Dawley rats were enrolled in this study. After right middle cerebral artery occlusion, rats were randomly assigned to one of f

This study presents different sagittal sacropelvic morphology and balance between the patients with/without SIJ pain following lumbar fusion surgery. The patients with SIJ pain showed retroversed pelvis and vertical sacrum while the patients without SIJ pain have similar morphologic features with asymptomatic populations in the literature.

This study describes the surgical technique and clinical results of video-assisted thoracoscopic surgery (VATS) assisted by an O-arm-based navigation system, used for the treatment of thoracic disk herniation (TDH). The trend toward the use of minimally invasive procedures with endoscopic visualization of the thoracic cavity in thoracic spine surgery has evolved. It is difficult to develop a new set of visuomotor skills unique to endoscopic procedures and understand the three-dimensional (3D) an

When treating intracranial vertebrobasilar dissecting aneurysms with brain stem compression, parent artery occlusion and flow diversion should be considered to reduce aneurysm size and improve the mRS score.

Flow diversion is effective for very large and giant aneurysms, but the outcomes require further improvement. The results of this study show that an incorporated vessel and excessive balloon angioplasty might compromise flow diversion. This finding can help improve the outcomes of flow diversion.

To present a rare case of a cystic giant schwannoma of the sacrum mimicking aneurysmal bone cyst (ABC). A 54-year-old man visited our institute complaining left leg weakness and sensory change for several years. Magnetic resonance imaging revealed a large multilocular cystic mass with canal invasion and bone erosion confined to left S1 body. The lesion showed multiple septal enhancement without definite solid component. Initially the tumor was considered as ABC. The patient underwent grossly-tot

The accurate and safe delivery of a microcatheter to a targeted shunt pouch is essential for successful transvenous embolization of intracranial dural arteriovenous fistulas. However, complex anatomy and variations in head and neck veins and occluded sinuses can hinder intraprocedural microcatheter delivery. In this study, we introduce an intraprocedural flat panel detector rotational angiography and image fusion technique to aid precise navigation inside the veins and proper placement of the mi

연구배경: 고혈압 환자에 대한 일차의료기관의 진료행태와 새로운 진료지침(JNC-7)을 비교 분석하여 진료지침의 시행률 및 진료행태의 근거 수준, 진료지침의 유용성을 알아보고자 본 연구를 시행하였다. 방법: 2005년도 대한가정의학과 개원의협의회의 회원주소록을 기초로 하여 주소가 명확하게 등재되어 있는 정회원 100...

연구 배경: 자살은 전 세계적으로 10대 사망원인 중에 하나이다. 최근 우리나라의 자살률은 크게 증가하고 있고, 특히 청소년의 자살률이 상대적으로 높게 나타나고 있다. 입시, 진로 등 자살에 대한 위험요인이 많은 고등학생들을 대상으로 청소년의 자살에 대한 인식과 자살충동 요인을 조사하여 자살 방지에 적합한 대책을 수립하는 데 도움을 주고자 한다. 방법: 2005년 6월 1일부터 2005년 7월 31일까지 서울과 지방의 8개 고등학교에 재학하고 있는 770명의 학생 중 불충분한 응답을 한 51명(6.6%)을 제외한 719명(93.3%)을 최종 연구대상으로 하였고, 설문조사의 결과는 SPSS 12.0 K for Windows를 사용하여 각 문항별로 빈도를 측정하였고 자살요인에 대한 통계처리의 검증은 χ2 검정과 Fisher의 직접 확률법, 로지스틱 회귀분석을 사용하여 변수간의 차이 및 상관관계가 있는지를 검증하였다. 결과: 연구 대상자는 남자 362명(50.3%), 여자 357명(49
