횡방향으로 유입되는 공기유동에서 연료 제트의 액주 및 액적영역의 궤적에 관한 연구를 수행하였다. 실험방법으로는 직접사진촬영방법과 평면레이저유도형광 기법을 사용하여 분석하였다. 본 연구의 목적은 공기유동 방향에 수직으로 분사되는 분무와 분사각도의 분무에서 궤적에 대한 경험식을 도출하여 기존 연구결과와 비교분석하고, 대향분사에서의 궤적에 대한 경험식을 도출하는데 있다. 실험을 통하여 액주 및 액적 영역의 궤적은 연료분사차압, 공기의 유속, 분사기 지름 크기, 분사각도에 의하여 결정되며, 정방향의 분무와... -

This study was conducted to provide normal reference features for canine and feline anal sacs using ultrasound, low-field magnetic resonance imaging (MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed. The visualization of anal sacs, which are located at distinct sites in dogs and cats, is possible with a... -
Effects of induced endometritis on uterine blood flow in cows as evaluated by transrectal Doppler sonography

This study was conducted to evaluate the effects of induced endometritis on uterine blood flow in cows. Transrectal Doppler sonography was performed on uterine arteries of six cyclic cows before and for 4 days after inducing acute endometritis by intrauterine infusion of 720 mg of policresulen, and for 4 days of the following estrous cycle. Time-averaged maximum velocity (TAMV) increased (p < 0.001) and pulsatility index (PI) decreased (p < 0.0001) within 1 h of policresulen... -
Evaluation of partial cranial cruciate ligament rupture with positive contrast computed tomographic arthrography in dogs

for the diagnosis of partial cranial cruciate ligament rupture. To obtain the sequential true transverse image of a cranial cruciate ligament, the computed tomography gantry was angled such that the scanning plane was parallel to the fibula. True transverse images of cranial cruciate ligaments were identified on every sequential image, beginning just proximal to the origin of the cranial cruciate ligament distal to the tibial attachment, after the administration of iodinated contrast medium. A... -
Glutamate and GABA concentrations in the cerebellum of novel ataxic mutant Pogo mice

The Pogo mouse is an autosomal recessive ataxic mutant that arose spontaneously in the inbred KJR/MsKist strain derived originally from Korean wild mice. The ataxic phenotype is characterized by difficulty in maintaining posture and side to side stability, faulty coordination between limbs and trunk, and the consequent inability to walk straight. In the present study, the cerebellar concentrations of glutamate and GABA were analyzed, since glutamate is a most prevalent excitatory... -
Gene Transfer of Cu/ZnSOD to Cerebral Vessels Prevents Subarachnoid Hemorrhage-induced Cerebral Vasospasm

The preventive effects of gene transfer of human copper/zinc superoxide dismutase (Cu/ZnSOD) on the development of cerebral vasospasm after subarachnoid hemorrhage (SAH) were examined using a rat model of SAH. An experimental SAH was produced by injecting autologous arterial blood twice into the cisterna magna, and the changes in the diameter of the middle cerebral artery (MCA) were measured. Rats subjected to SAH exhibited a decreased diameter with an increased wall thickness of MCA that were... -

포만중추 (satiety center)를 자극하여 음식섭취를 억제한다고 알려진 CCK-8을 흰쥐 복강에 투여하여, 흰쥐 뇌의 도파민 변화에 대한 CCK-8의 효과를 관찰하였다. 흰쥐 뇌의 부위별 도파민 함량은 HPLC-ECD방법으로 측정하였으며, 시상하부와 흑질에서의 TH-immunoreactive neuron은 면역조직화학법과 영상분석법을 시행하였다. 굶긴 쥐에서는 정상 쥐에 비하여, 도파민 함량이 전두 피질, 해마, 시상하부 및 편도체에서 각각 감소하였다. CCK-8을 투여한 쥐는 정상 쥐와 굶긴 쥐에 비하여, 도파민 함량이 시상하부에서 의미있게...
