| Subarachnoid infusion of most contrast mediums and the steps involved in performing a cervical myelography have adverse affects that can discourage its use in the radiographic diagnosis of spinal cord diseases. Thus, the cardiovascular and respiratory alterations associated with neck flexion, subarachnoid puncture, and cerebrospinal fluid drainage during subarachnoid infusion of ioversol (320mgI/mL) in dogs under general anesthesia using isoflurane were evaluated. The dogs received subarachnoid infusion of autologous cerebrospinal fluid kept at 38°C - control group (GC); ioversol 0.3mL/kg at 25°C (GI25) and ioversol 0.3mL/kg heated to 38°C (GI38). Each dog had its heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP),... |

| The effects of subarachnoid administration of iohexol on intracranial hemodynamic in dogs anesthetized with propofol or sevoflurane were evaluated. Thirty adult animals (10.9±2.9kg) were distributed into two groups: PG, where propofol was used for induction (10±0.5mg/kg), followed by a continuous rate infusion at 0.55±0.15mg/kg/hour, and SG, where sevoflurane was administered for induction (2.5 MAC) and for anesthetic maintenance (1.5 MAC). A fiberoptic catheter was implanted on the right superficial cerebral cortex to monitor intracranial pressure (ICP). After 30 minutes, cerebrospinal fluid (CSF) was collected at the cisterna magna and iohexol was injected. The measurements were performed before CSF collection (TA), after the iohexol injection (T0), and... |

| This study aimed to assess the opacification period and diagnostic quality of ioversol 240 mg I/ml in the thoracic and lumbar regions after intracisternally injected, and evaluate its effects on the nervous system by clinical and neurological examinations. Thirty clinically normal non-descript dogs without sex distinction, weighing 9-12 kg were divided into three groups of 10 animals each. All the animals were anaesthetized using diazepam and thiopental sodium. Ioversol was injected at a dose of 0.5ml/kg. Cervical radiographs after 5 minutes to confirm injection of the contrast, and thoracolumbar radiographs after 30, 40, 50 and 60 minutes to evaluate the opacification period were taken. Clinical and neurological examinations were performed daily until 7,... |

| 脊髄造影後の後遺障害発生のメカニズムについて、脊髄終末が犬より尾側に位置するウサギを用いて、行動観察、神経学的および病理組織学的に検討した。実験にはウサギ（n=12）を使用し、実験群は、(1)脊髄穿刺群、(2)生理的食塩水注入群、(3)等浸透圧ヨード造影剤イオジキサノール注入群、(4)低浸透圧ヨード造影剤イオヘキソール注入群とした。全身麻酔下で第5-6腰椎間より脊髄穿刺あるいは薬液を脊髄実質内に直接注入し、処置48時間後に行動観察および神経学的検査を、72時間後に病理組織学的検査を行うとともに、切片上での損傷面積率について評価した。神経学的検査では生理的食塩水注入群、イオジキサノール注入群およびイオヘキソール注入群で異常が認められた。また、穿刺部位の脊髄損傷面積率についても脊髄穿刺群と生理的食塩水注入群との間に明らかな差異が認められた。本研究の結果から、脊髄への薬液注入による組織の圧迫は、脊髄造影後の後遺障害を発生させる要因と考えられた。今後、脊髄造影を行う際には、脊髄針からの脳脊髄液の逆流を必ず確認し、造影剤の実質内注入を疑った場合には直ちに検査を中止することを提案する。なお、将来は獣医臨床における、より安全な脊髄造影手技の開発が望まれる。 The purpose of this experiment is to characterize the aftereffects of myelography of canine spinal cords using rabbits，since the distal end of the spinal cord of rabbits is more caudal than that of dogs. Twelve healthy New Zealand White... |
