        급성 뇌경색에서 시간 경과에 따른 혈청 신경원 특이 에놀라제(neuron specific enolase)의 변화

        구본대,정경천 대한신경과학회 2009 대한신경과학회지 Vol.27 No.1

        Background: Neuron-specific enolase (NSE) is a useful indicator of neuronal injury in acute cerebral infarction. We investigated the changes in serial serum NSE levels in patients with acute cerebral infarction. Methods: We measured serial serum NSE levels at 24, 48, 72, and 96 hours, and 2 weeks after the onset of cerebral infarction in 30 patients (15 territorial and 15 lacunar infarctions). We also measured the NSE levels in age-matched controls (n=15) who had no evidence of acute stroke or other neurological disorders. The NSE level was measured using a radioimmunoassay. Results: The initial serum NSE level was significantly higher in the cerebral infarction group than in the control group (6.6±2 vs 4.7±1.6 ng/mL [mean±SD], p=0.006). This difference was also observed between the territorial and lacunar infarction groups until 72 hours after the cerebral infarction. The serum NSE level peaked at 72 hours after the infarction in both lacunar and territorial infarction groups. The correlation between the NSE level and the score on the NIH Stroke Scale was strongest at 48 hours after the cerebral infarction (r=0.469). Conclusions: Serum NSE level can be a good indicator for distinguishing lacunar from territorial infarction during the acute stage of cerebral infarction.

        중증 뇌손상 환자에서 뇌동정맥 산소함유량차이와 지연성 뇌경색 발생과의 관계

        윤승환,조준,문창택,장상근,박형천,박현선,김은영,Youn, Seung-Hwan,Cho, Joon,Moon, Chang-Taek,Chang, Sang-Keun,Park, Hyung-Chun,Park, Hyeon-Seon,Kim, Eun-Young 대한신경외과학회 2000 Journal of Korean neurosurgical society Vol.29 No.4

        Objective : This study was performed to evaluate the relationships among intracranial pressure(ICP), cerebral perfusion pressure(CPP), and cerebral arteriovenous oxygen difference($AVDO_2$) which were used as parameters of adequacy of cerebral blood flow to support cerebral metabolism after severe head injury and also to examine the association between delayed cerebral infarction and outcome. Material and Method : The authors studied the ICP, CPP and $AVDO_2$ before and after treatment on 34 head-injured patients from June 1996 to December 1997 and examined the association with the change of an ICP, CPP and $AVDO_2$ following treatment and the development of delayed cerebral infarction. Sixteen patients underwent craniotomy for hematoma evacuation and eighteen patients received mannitol to decrease ICP. Results : The development of delayed cerebral infarction was demonstrated in 3(42.9%) out of 7 patients in no improvement group and 13(48.1%) out of 27 patients in improvement group with an increased ICP following treatment. Also, the development of delayed cerebral infarction was demonstrated in 8(50%) out of 16 patients in no improvement group and 8(44.4%) out of 18 patients in improvement group with a decreased CPP following treatment. The association with changes of ICP and CPP following treatment and development of delayed cerebral infarction was not statistically significant(p>0.01). However, 11(78.6%) out of 14 patients who demonstrated an increase in $AVDO_2$ and 5(25%) out of 20 patients who demonstrated a decrease in $AVDO_2$ following treatment developed delayed cerebral infarction. No improvement(reduction) in $AVDO_2$ following treatment was significantly associated with the development of delayed cerebral infarction(p<0.01). All of 16 patients with delayed cerebral infarction showed poor prognosis. Conlcusion : The change of $AVDO_2$ rather than those of ICP and CPP was considered more important factor for the development of the delayed cerebral infarction and poor outcome.

        局所 腦硬塞 急性期에서 再灌流에 關한 實驗的 硏究

        김현집,정희원,한대희,심보성 대한신경외과학회 1984 Journal of Korean neurosurgical society Vol.13 No.2

        Cerebral revascularization has been popular since the introduction of microsurgical technique into the neurosurgery. But there is still no satisfactory measures in the treatment of acute cerebral infarction caused by obstruction of the major cerebral artery. It was also reported that early restoration of blood flow into the infarcted area frequently aggravated the cerebral infarction. The purpose of this experiment is to establish an experimental animal model for temporary occlusion of the middle cerebral artery, and to estimate the tolerable duration of cerebral ischemia without occurrence of hemorrhagic infarction and severe cerebral edema after restoration of blood flow. For temporary arterial occlusion, 80 nylon snare was prepared around the proximal middle cerebral artery through transorbital approach. 48 hours after operation, alert cats were subjected to temporary occlusion of the artery. Occlusion of the artery for 1, 2,4, or 6 hours was followed by recirculation for 2 hours. Immediately after sacrifice, 2% solution of triphenyl tetrazolium chloride was injected into common carotid arteries. Clinical observation was done during the whole procedure of the experiment. And brain was examined grossly for cerebral infarction, hemispheric swelling and hemorrhagic infarction. The results were as follows; 1) With transorbital snare technique for temporary occlusion of the middle cerebral artery, relatively constant cerebral infarction could be produced in cats. 2) The initial clinical findings were charcteristic and similar in all cats whose middle cerebral arteries were occluded. These consisted of contralateral hemiparesis, rapid circling and tonic deviation of the head and neck toward the side of arterial occlusion. After 5-20 minutes rapid circling gait and tonic deviation disappeared, but hemiparesis and slow circling gait continued throughout the experiment. 3) In contrast to stable clinical states in animals of 8 hour occlusion group and recirculation groups after I or 2 hours of arterial occlusion, over half of cats whose middle cerebral arteries were occluded for 4 hours or more became clinically aggravated after recirculation (p<0.05). 4) There was a tendency that the infarcted area unstained with 2% solution of triphenyl tetrazolium chloride was progressively enlarged as the duration of arterial occlusion increased, but the difference was not stastically significant (p>0.05). 5) Cerebral hemispheric swelling in cats of recirculation groups became progressively increased as the duration, of arterial occlusion increased (p<0.05), and had close correlation with clinical findings. 6) In cats whose middle cerebral arteries were occluded for 6 hours, the rate of gross hemorrhagic infarction increased abruptly.

        Effects of Snake Venom Pharmacopuncture on a Mouse model of Cerebral Infarction

        최철훈,송호섭 대한침구의학회 2019 대한침구의학회지 Vol.36 No.3

        Background: This study investigated the effects of Vipera lebetina turanica snake venom (SV) on cerebral infarction induced by middle cerebral artery occlusion in mice. Methods: Following cerebral infarction, SV was injected intravenously or added to BV2 cell culture. Tissue injury was detected using triphenyltetrazolium chloride (TTC) staining, neurological deficit score, NO, ROS, and GSH/GSSG assays, qPCR, Western blot, and cell viability. Results: Cerebral infarction caused by middle cerebral artery occlusion as observed by TTC staining, showed SV inhibited cell death, reducing the number of brain cells injured due to infarction. SV treatment for cerebral infarction showed a significant decrease in abnormal behavior, as determined by the neurological deficit score. The oxidation and inflammation of the cells that had cerebral infarction caused by middle cerebral artery occlusion (NO assay, ROS, GSH/GSSG assay, and qPCR), showed significant protection by SV. Western blot of brain infarction cells showed the expression of iNOS, COX-2, p-IkB-α, P38, p-JNK, p-ERK to be lower in the SV group. In addition, the expression of IkB increased. BV2 cells were viable when treated with SV at 20 μg/mL or less. Western blot of BV2 cells, treated with 0.625, 1.5, 2.5 μg/mL of SV, showed a significant decrease in the expression of p-IkB-α, p-JNK, iNOS, and COX-2 on BV2 cells induced by LPS. Conclusion: SV showed anti-inflammatory and anti-oxidant effects against cerebral infarction and inflammation.

        Clinical Factors Associated with Deep Vein Thrombosis in Rehabilitation Patients Suspected of Thromboembolism after Cerebral Infarction

        김원준,배수환,강천지,김대열 대한뇌신경재활학회 2020 뇌신경재활 Vol.13 No.2

        The aim of this study is to investigate the association between characteristics of cerebral infarction lesion (vascular territory, etiology, and size), functional status and the occurrence of thromboembolism in patients suspected of having thromboembolism in a rehabilitation setting after cerebral infarction. Cerebral infarction patients who were suspected of having thromboembolism and who had undergone deep vein thrombosis (DVT) evaluation were included in analyses. Of the total 916 cerebral infarction patients, 65 patients were suspected of having DVT; 27 patients belonged to the DVT group and 38 patients belonged to the non-DVT group. The DVT (+) group was more likely to have a higher ratio of female, previous DVT history, middle cerebral artery (MCA) infarction, large arterial disease, modified Rankin Scale (mRS) score 5, abnormal speech and higher D-dimer. In multivariate logistic regression analysis, female sex, MCA infarction and mRS score 5 were significantly associated with the occurrence of thromboembolism in patients suspected of having thromboembolism. In contrast, other functional status, cerebral infarction etiology (Trial of ORG 10172 in Acute Stroke Treatment [TOAST] classification), and infarct volume were not associated with the occurrence of thromboembolism. In this study, female gender, MCA infarction, and mRS score 5 could be potential risk factors for thromboembolism in rehabilitation patients after cerebral infarction.

        쯔쯔가무시병과 동반된 뇌경색의 특징

        최판규(Pahn Kyu Choi),강현구(Hyun Goo Kang) 한국산학기술학회 2017 한국산학기술학회논문지 Vol.18 No.10

        본 연구는 2007년 1월부터 2015년 12월까지 본원에서 쯔쯔가무시병으로 진단을 받고 치료 중인 상태에서 뇌경색이 발생하거나, 뇌경색이 생겨 입원 치료를 받던 중 쯔쯔가무시병이 발견된 16명의/ 환자를 대상으로 하였다. 급성기 뇌경색의 진단은 뇌자기공명영상 및 뇌자기공명혈관영상으로 하였으며 쯔쯔가무시병의 진단은 PCR (Polymerase chain reaction)로 하였다. 일반적인 뇌경색과 쯔쯔가무시병을 동반한 뇌경색의 차이점을 구별하기 위해 내원시 혈압과 체온을 측정하여 보았다. 일반적으로 급성기 뇌경색에서는 혈압이 올라가는데 흥미롭게도 본 연구에서는 수축기 혈압이 130mmHg 미만인 환자가 12명으로 급성기 뇌경색에서 흔히 보이는 혈압 양상과는 다른 모습을 보였다. 쯔쯔가무시병을 동반한 뇌경색의 특징을 알아보기 위해 발병 위치 및 단일 혹은 다발성 뇌경색 여부를 확인하여 보았는데. 앞순환 동맥 영역의 뇌경색 발생 환자가 13명이었으며 뒤순환 동맥 영역의 뇌경색 발생 환자는 3명이었다. 응고장애를 진단하기 위해 트롬보플라스틴시간(Prothrombin Time, PT), 활성화부분트롬보플라스틴시간(activated partial thromboplastin time, aPTT), D-dimer, 섬유소원(fibrinogen), 섬유소분해산물(fibrin degradation product, FDP)를 기록하였다. 뇌경색시 일반적으로 수치가 증가하는 것으로 알려진 D-dimer의 경우 13명의 환자에서 큰 폭의 증가 소견을 보였다. 섬유소분해산물(FDP)는 15명의 환자에서 큰 폭의 증가 소견을 보였다. 쯔쯔가무시병의 병태생리학적 기전은 혈관염으로 알려져 있는데 이로 인한 대뇌혈관의 내피세포 손상 및 증식이 있을 수 있고 그 과정에서 응고장애가 동반되어 뇌경색이 발생할 수 있다. 또는 내피세포 손상 및 증식이 없더라도 혈관염으로 인한 혈관연축이 발생하여 혈관수축이 오며 뇌경색이 발생 할 수도 있다. This study was performed on16 patients diagnosed with tsutsugamushi disease and cerebral infarction from January 2007 to December 2015. An acute cerebral infarction was diagnosed bybrain MRI and MRA. Tsutsugamushi disease was diagnosed using a polymerase chain reaction. To distinguish the difference between the generalized cerebral infarction and infarction with tsutsugamushi disease, the blood pressure and body temperature were measured uponadmission. In general, the blood pressure increasesduring an acute cerebral infarction. Interestingly, in this study, 12 patients showed a systolic blood pressure less than 130mmHg uponadmission. The location of the cerebral infarction and whether single or multiple cerebral infarction were examined. Thirteen patients had a cerebral infarction in anterior circulation and 3 patients developed in posterior circulation. Toevaluate the coagulation disorders, prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimer, fibrinogen, fibrin degradation product (FDP). D-dimer, which is generally known to increase in an acute cerebral infarction, showed a significant increase in the 13 patients. Fibrin degradation products (FDP) showed a significant increase in 15 patients. The pathophysiological mechanism of tsutsugamushi disease is known as vasculitis, which may result in an endothelial cell injury and proliferation of the endothelial wall, which may lead to a cerebral infarction accompanied by coagulopathy. Without endothelial cell damage and proliferation, a vasospasm caused by vasculitis may cause vasoconstriction and cerebral infarction.
