  • The cerebral infarction arised from occulsion of cerebral artery has a high mortality rate and fatal sequelae. Sohabhyangwon(蘇合香元) is generally regarded to have a effect of walking up the patient from unconsiousness and promoting the flow of Qj(氣) by warming channel. METHOD The purpose of this study is to find out the effections of Sohabhyangwon(蘇合香元) on regional cerebral blood flow and relative cerebral infarction area in the experimentally induced infartion in rats In this experiment, 12 Spraque-Dawley rats weighting 280-350g were used. Cerebral ischemia induced by intraluminal suture technique of Kozumi's and Zea-Longer's method. $Co_{2},\;O_2$, pH, arterial blood pressure in rats were checked by Blood Gas Analyzer every 30 minutes for 2 hours. And regional cerebral blood flow were checking by hydrogen clearance technique, cerebral infarcted area was megsured by Image Analysis System. RESULTS 1. During the experiment, $CO_{2},\;O_2$, pH, arterial blood pressure in rats had no change in both sample group and control group. 2. Cortical cerebral blood flow decreased at same rate in both sample group and control group after inducing cerebral infarction. 3. On comparison of relative cerebral infarcted area, Sohabhyangwon(蘇合香元) perfused group showed a significant decrease. CONCLUSION According to the result above, Sohabhyangwon has a protection effect on cranial nerve and-has no effect on cerebral blood flow.

  • Objective : The authors investigate the spatial characteristics of apoptotic genes expressed around the focal cerebral infarction, and attempted to explain the penumbra with them. Methods : A delayed focal cerebral infarction was created in twelve adult Sprague-Dawley rats. We performed the immunohistochemical staining for the apoptosis, bcl-2 and p53 proteins and measured the local cerebral blood flow [CBF] at the infarction core area and peri-infarct area pre- and intra-operatively. The peri-infarct area was divided into six sectors by distance from the infarction border. Results : The size [$mm^2$] of apoptosis, bcl-2, and p53 areas were $3.1{\pm}1.2$, $4.7{\pm}2.1$, and $6.8{\pm}2.4$, respectively. Apoptosis, bcl-2 or p53 positive cells were concentrated at the peri-infarct area adjacent to the infarction core. Their numbers reduced peripherally, which was inversely proportional to the local CBF. The p53 area seems to overlap with and larger than the ischemic penumbra. Conclusion : The p53 positive area provides a substitutive method defining the penumbra under the molecular base of knowledge.

  • Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by sudden-onset headache with focal neurologic deficit and prolonged but reversible multifocal narrowing of the distal cerebral arteries. Stroke, either hemorrhagic or ischemic, is a relatively frequent presentation in RCVS, but progressive manifestations of subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction in a patient is seldom described. We report a rare case of a 56-year-old woman with reversible cerebral vasoconstriction syndrome consecutively presenting as cortical subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral infarction. When she complained of severe headache with subtle cortical subarachnoid hemorrhage, her angiography was non-specific. But, computed tomographic angiography showed typical angiographic features of this syndrome after four days. Day 12, she suffered mental deterioration and hemiplegia due to contralateral intracerebral hematoma, and she was surgically treated. For recurrent attacks of headache, medical management with calcium channel blockers has been instituted. Normalized angiographic features were documented after 8 weeks. Reversible cerebral vasoconstriction syndrome should be considered as differential diagnosis of non-aneurysmal subarachnoid hemorrhage, and repeated angiography is recommended for the diagnosis of this under-recognized syndrome.

  • Objective : The aim of this study was to analyze the treatment results and prognostic factors in patients with massive cerebral infarction who underwent decompressive craniectomy. Methods : From January 2000 to December 2005, we performed decompressive craniectomy in 24 patients with massive cerebral infarction. We retrospectively reviewed the medical records, radiological findings, initial clinical assessment using the Glasgow Coma Scale, serial computerized tomography (CT) with measurement of midline and septum pellucidum shift, and cerebral infarction territories. Patients were evaluated based on the following factors : the pre- and post-operative midline shifting on CT scan, infarction area or its dominancy, consciousness level, pupillary light reflex and Glasgow Outcome Scale. Results : All 24 patients (11 men, 13 women; mean age, 63 years; right middle cerebral artery (MCA) territory, 17 patients; left MCA territory, 7 patients) were treated with large decompressive craniectomy and duroplasty. The average time interval between the onset of symptoms and surgical decompression was 2.5 days. The mean Glasgow Coma Scale was 12.4 on admission and 8.3 preoperatively. Of the 24 surgically treated patients, the good outcome group (Group 2 : GOS 4-5) comprised 9 cases and the poor outcome group (Group1 : GOS 1-3) comprised 15 cases. Conclusion : We consider decompressive craniectomy for large hemispheric infarction as a life-saving procedure. Good preoperative GCS, late clinical deterioration, small size of the infarction area, absence of anisocoria, and preoperative midline shift less than 11mm were considered to be positive predictors of good outcome. Careful patient selection based on the above-mentioned factors and early operation may improve the functional outcome of surgical management for large hemispheric infarction.

  • Fibromuscular dysplasiais an uncommon condition of idiopathic, non-inflammatory and non-atherosclerotic disease of the musculature of arterial walls. The disease is rare, but it commonly affects young and middle aged women. Isolated intracranial cerebral fibromuscular dysplasia is extremely rare because cerebral fibromuscular dysplasia usually affects extracranial vessels. A 20-year-old woman was admitted with light hemiplegia and global aphasia. Brain MRI and MRA demonstrated acute left middle cerebral artery territory infarction with a multifocal stenosis and dilatation of the left middle cerebra artery and left internal carotid. The characteristic conventional cerebral angiographic findings demonstrated a typical string-of-beads appearance in the left distal internal carotid artery and proxiaml portion of the left middle cerebral artery, which suggested a medial type fibromuscular dysplasia. We report a case of isolated intracranial fibromuscular dysplasia with left middle cerebral artery territory infarction. Fibromuscular dysplasia should he considered as a stroke risk factors in children and young adults, especially in patients with no known cardiovascular risk factors.

  • We report a rare case of Williams syndrome accompanying moyamoya disease in whom postoperative global cerebral infarction occurred unpredictably. Williams syndrome is an uncommon hereditary disorder associated with the connective tissue abnormalities and cardiovascular disease. To our knowledge, our case report is the second case of Williams syndrome accompanying moyamoya disease. A 9-year-old boy was presented with right hemiparesis after second operation for coarctation of aorta. He was diagnosed as having Williams syndrome at the age of 1 year. Brain MRI showed left cerebral cortical infarction, and angiography showed severe stenosis of bilateral internal carotid arteries and moyamoya vessels. To reduce the risk of furthermore cerebral infarction, we performed indirect anastomosis successfully. Postoperatively, the patient recovered well, but at postoperative third day, without any unusual predictive abnormal findings the patient's pupils were suddenly dilated. Brain CT showed the global cerebral infarction. Despite of vigorous treatment, the patient was not recovered and fell in brain death one week later. We suggest that in this kind of labile patient with Williams syndrome accompanying moyamoya disease, postoperative sedation should be done with more thorough strict patient monitoring than usual moyamoya patients. Also, we should decide the revascularization surgery more cautiously than usual moyamoya disease. The possibility of unpredictable postoperative ischemic complication should be kept in mind.

  • This study is about the quality of life of cerebral infarction patients' guardians. The subject of this study was a group of 159 guardians of patients diagnosed of cerebral infarction and being hospitalised in a general hospital located in Seoul. The measurement tool consisted of quality of life of cerebral infarction patients' guardian, self-esteem, burden of responsibility, family unity, health status of the guardian. The collected data have been processed using SPSS/PC 12.0 programme: The results of this study are as follows: 1. The point for quality of life of cerebral infarction patients' guardians was 3.08(five-point scale), and for the related factors, the points for self-esteem was 3.67, burden of responsibility was 3.26, family unity was 4.13, health status was 6.10(ten-point scale). 2. There was a significant difference in the quality of life according to Self-esteem, Burden of responsibility, Family unity and general characteristics. 3. In the quality of life of cerebral infarction patients' guardians, a positive correlation was noted in some factors according to the characteristics of the guardians such as health status, self-esteem, family unity, monthly income, and time spent for caring the patient. Whilst a negative correlation was noted in the others such as burden of responsibility and age of the guardian. By confirming the results above, it is concluded that we must understand the major factors which are related to quality of life, find the causes that deteriorate the quality of life, and apply proper nursing intervention to improve the quality of life of cerebral infarction patients' guardians.

  • Background: The current study evaluated the hospital utilization and characteristics of patients who received health care services for acute cerebral infarction outside their own residential area. Methods: Using the 2014 national patient survey data, information on 2,982 patients diagnosed with acute cerebral infarction through emergency department were retrieved for the analyses. Multiple logistic regression was performed to investigate the characteristics associated with using hospitals outside residential area among patients diagnosed with acute cerebral infarction. Results: Fifteen point nine percent of patients admitted for acute cerebral infarction utilized hospitals outside their residential area. Patients residing in a province were 7.7 times more likely to utilize hospitals located outside their residential areas compared to those living in Seoul metropolitan city. Patients living in Gangwon and Jeolla were 0.26 times and 0.48 times more likely to go to hospitals in different geographical areas. Also, patients within the age group of 80 years and over were 0.65 times less likely to be admitted to hospitals outside their residential area compared to those in their 40s-50s. Conclusion: The use of hospitals outside patient's residential area is shown to be substantial, given that the acute cerebral infarction requires immediate recognition and treatment. The findings on the geographical differences in the hospital utilization suggest further investigation.
