  • Background : The vasoreactivity of cerebral artery is currently the subject of increasing interest. Transcranial Doppler Sonography(TCD) is an accurate method of monitoring the blood flow velocities of the cerebral artery. We wished to assess the vasoreactivity between age-matched normal and cerebral infarction group. Method : We performed TCD findings in 40 normals and 20 cb-inf. subjects who arrived at hospital during 48 hours after attack. The former were devided into twenties normal group and fifties normal group. Result : 1. Fibrinogen levels showed significant changes between age-matched normal and cb-inf. group. 2. $V^{MEAN}$ of the both side Carotid Siphon during rest state increased significantly in cb-inf. group as compared with the age-matched normal group. 3. $V^{MEAN}and\;V^{MAX}$ of the both side carotid siphon during breath-hold state increased significantly in cb-inf. group as compared with the age-matched normal group. 4. Vasoreactivity of cerebral artery increased significantly in cb-inf. group as compared with the age-matched normal group. 5. $V^{MEAN}and\;V^{MAX}$ of the both side Radial artery during heat-stimuration state increased significantly in cb-inf. group as compared with the age-matched normal group. 6. Vasoreactivity of Radial artery increased significantly in cb-inf. group as compared with the age-matched normal group.

  • Aneurysm of the common carotid artery is uncommon. In surgery for carotid aneurysm there is the risk of endangering cerebral circulation during the period of arterial occlusion necessary for the resection. Therefore a method which will allow adequate cerebral circulation during carotid artery anastomisis is obviously to be desired. A case of aneurysm of the common carotid artery is presented in which the aneurysm was partially resected and the artery was reconstructed by end to end anastomosis. while cerebral circulation was maintained by an internal polyethylene shunt. The occurrence of this aneurysm was associated with a chronic stasis ulcer of the left fore leg. On this basis the aneurysm was thought to be of mycotic origin though this has not been proved histologically or by laboratory methods. The literature on aneurysm of the carotid artery is briefly reviewed.

  • Objectives : In conditions of brain infarction, irreversible axon damage occurs in the central nerve system (CNS), because gliosis becomes a physical and a mechanical barrier to axonal regeneration. Reactive gliosis induced by ischemic injury such as middle cerebral artery occlusion is involved with up-regulation of GFAP and CD81. This study was undertaken to examine the effect of the Gongjin-dan (GJD) on CD81 and GFAP expression and its pathway in the rat brain following middle cerebral artery occlusion (MCAO). Methods : In order to study ischemic injuries on the brain, infarction was induced by MCAO using insertion of a single nylon thread, through the internal carotid artery, into a middle cerebral artery. Cresyl violet staining, cerebral infarction size measurement, immunohistochemistry and microscopic examination were used to detect the expression of CD81 and GFAP and the effect on the infarct size and pyramidal cell death in the brain of the rat with cerebral infarction induced by MCAO. Also, c-Fos and ERK expression were measured to investigate the signaling pathway after GJD administration in MCAO rats. Results : Measuring the size of cerebral infarction induced by MCAO in the rat after injection of GJD showed the size had decreased. GJD administration showed pyramidal cell death protection in the hippocampus in the MCAO rat. GJD administration decreased GF AP expression in the MCAO rat. GJD administration decreased CD81 expression in the MCAO rat. GJD administration induced up-regulation of c-FOS expression compared with MCAO. GJD administration induced down-regulation of ERK expression compared with MCAO. Conclusion : We observed that GJD could suppress the reactive gliosis, which disturbs the axonal regeneration in the brain of a rat with cerebral infarction after MCAO by controlling the expression of CD81 and GFAP. The effect may be modulated by the regulation of c-Fos and ERK. These results suggest that GJD can be a candidate to regenerate CNS injury.

  • Spontaneous dissection of the anterior cerebral artery is an unusual cause of subarachnoid hemorrhage. We present a case of a dissecting aneurysm of the anterior cerebral artery presenting with subarachnoid hemorrhage. A 51-year-old woman presented to our hospital with severe headache. Neurological examination demonstrated neck stiffness, decreased visual acuity of the left eye, and left ankle weakness. Computed tomographic scans showed subarachnoid hemorrhage. The initial cerebral angiogram demonstrated a slightly narrowed caliber and mild poststenotic dilation of the right A1 segment. A second cerebral angiogram 14 days later revealed no change in the focal narrowing of the proximal A1 segment but marked progression of the dilatation of the distal A1 segment. Right pterional craniotomy was performed. A sausage-like dilation of the right A1 segment was found with no definite mural hematoma. This abnormal right A1 segment was wrapped with a Sundt clip. A postoperative computed tomographic scan revealed Infarction of the right head of the caudate nucleus and the anterior limb of the right internal capsule. If a dissecting aneurysm is suspected, serial angiographic studies should be performed because of the possibility of dynamic changes over a short period.

  • This study was performed to provide basic data that predict the application of Saengmaegsan(SMS) as medicinal food. SMS has been used in oriental medicine for many years as a therapeutic agent for cerebral disease. We examined the effects of SMS on physiological function in isolated abdominal aorta and femoral artery from rabbit and measured the changes of regional cerebral hood flow(rCBF), which was continually monitored by laser-doppler flowmeter and pressure transducer in anesthetized adult Spargue-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. The contraction forces by injection of norephinephrine in isolated abdominal aorta and femoral artery were significantly decreased in each concentration of SMS treatment compared with control. rCBF was increased by SMS in a dose-dependent manner. These results suggest that SMS causes a diverse response of rCBF and arterial diameter. These mechanism in rCBF increase may be mediated by prostaglandis, cyclic GMP and adrenergic $\beta-receptor$. Also mechanism in artery contraction decrease is also mediated by prostaglandis and cyclic GMP. These results indicate that SMS can be nsed as a safe and clinically applicable as a supplementation of diet therapy for cerebral cardiovascular disease patients.

  • Arteriosclerosis is a pathologic term that contains hardening of arterial wall, loss of arterial elasticity and stenosis of artery. To diagnose this disease, conventional angiography, MRA, transcranial doppler ultrasonography are commonly used. And it causes various clinical phases by a region of the disease. In oriental medicine, arteriosclerosis is classified into congested fluids(痰飮), blood stasis(瘀血), stagnation of Gi(氣滯) and treated by Herb-Med, acupuncture, cupping, moxibustion, and the like. The purpose of this study was to investigate the effect of oriental medical therapy on cerebral arteriosclerosis. A patient with cerebrovascular disease admitted due to dizziness, mild dysarthria, tinnitus, anxiety disorder and his Brain MRA showed severe arteriosclerosis in right anterior cerebral artery(ACA) and middle cerebral artery(MCA). Every day, we administered to patient Herb Med and Herb pills. Also, acupuncture, moxibustion were done, too. As a result of the treatment, the patient's follow up Brain MRA showed improved state of ACA stenosis.

  • Isolated symptomatic occlusion of the anterior cerebral artery (ACA) is a rare condition and until date, only few cases regarding the revascularization of the ACA have been reported. This paper reports on successful attempt to revascularize the ACA using superficial temporal artery (STA) in patient with isolated symptomatic occlusion of the ACA. A 69-year-old man presented with several episodes of transient weakness involving left lower extremity. Cerebral angiography showed occlusion of the right ACA at the A2 segment. After medical treatment failure, the patient underwent STA-ACA bypass surgery. Subsequent to surgery, there was immediate disappearance of transient ischemic attack and follow-up angiography showed favorable revascularization of the ACA territory. Bypass surgery can be considered in the patients with symptomatic occlusion of the ACA, who have experienced failure in medical treatment.
