Objective : The purpose of this study is to present the epidemiological data on patients with a stroke admitted to Department of Acupuncture & Moxibustion, Oriental Medical Hospital Kyung Hee University and to investigate the difference between preceding diseases of stroke. Methods : We reviewed medical records of 700 patients with a stroke admitted to Department of Acupuncture & Moxibustion, Oriental Medical Hospital, Kyung Hee University. Results: The incidence of cerebral infarction was 6.7 times that of cerebral hemorrhage. The incidence in males was 1.28 times of that in females. The incidence of stroke increased with aging and more cerebral hemorrhage occured in lower age group than cerebral infarction. There was higher morbidity in October, during the changing of the seasons, than any other months. Hypertension was the most common preceding disease followed by diabetis mellitus, heart disease, hyperlipidemia, and according to Odds's ratio for Male/Female, the probability of having preceding diseases was higher in females than males. In cerebral infarction, MCA territory was the most frequent lesion sites. Of the cerebral hemorrhage, basal ganglia (60%) was the most commonly involved site which was followed by thalamus(33.3%), cortex (3.3%) and subcortex (2.2%). The most common symptom accompanied by stroke was motor dysfunction which was followed by verbal disturbance, urination disorder and dysphagia. Conclusion : This study showed the trends of stroke in Oriental medical center. We expects that Multicenter cooperative and prospective study including Oriental Medicine will be inspired by this study for establishing more accurate chacteristics of stroke in Korea in the future.

허혈성 뇌졸중 환자에서 운동장애의 판단 및 예후 판정에 운동유발전위 (motor evoked potential : MEP)의 유용성을 알아보기 위해 정상대조군 24례와 허혈성 뇌졸중 환자 24례를 대상으로 대뇌피질 및 척추부위에 자기자극을 가하며 단모지외전근 및 무지외전근에서 MEP를 기록하였고 각각의 근육에서 대뇌피질을 자극하여 기록된 MEP의 잠복기에서 척추부위를 자극하여 기록된 MEP의 잠복기를 감한 차이로 CMCT를 산출하였다. 대조군은 24례 모두에게 MEP를 유발할 수 있었고 환자군에서는 24폐 중 무반응을 나타낸 경우가 각 근육에서 11례였다. 정상대조군과 MEP를 유발할 수 있었던 뇌졸중 환자에서 단모지외전근에서의 평균 CMCT는 각각 $8.6{\pm}1.4$msec, $9.4{\pm}2.3$msec로 통계적 유의성은 없었고, 무지외전근에서는 $15.1{\pm}2.1$msec, $18.8{\pm}3.9$msec로 유의한 차이를 보였다(p<0.01). 허혈성 뇌졸중 환자에서 추체로 또는 중심피질 병변일 때 혹은 급성기의 운동장애가 심할 때 대뇌피질 자기자극에 무반응을 보인 경우가 많았고, 추체로를 제외한 피질하 병변일 때 혹은 경한 운동장애를 보일 때 CMCT가 정상인 경우가 많았다. 운동장애를 보였던 환자중 급성기의 CMCT가 정상인 경우는 1~2개월 후 상당한 운동회복을 보였고 대뇌피질 자기자극에 반응이 없을 때 운동회복은 미약하였다. 이로 미루어 MEP는 안전하고 간편한 중추성 운동신경계 전달경로의 전기생리학적 검사로써 뇌졸중환자의 운동장애를 판단하는 데 도움을 주고 급성기 운동장애의 예후를 예측하는 데 하나의 지표가 될 수 있을 것이라 사료된다.

In order to find the effects of physical therapy on the recovery of motor functions and mental state, a survey was conducted to 63 patients who, diagnosed as stroke by brain CT, had been hospitalized in a university medical center located in Jeonbuk provincial area from December 2000 to August 2001. The outcomes of the survey are as follows: 1. The subjects of the study were composed of 35 males(55.6%) and 28 females(44.4%), with 34(54.0%) below 60 in age and 29(46.0%) older than 60 years. 2. As to type of lesion, the surveyed patients were divided into 28(44.4%) with cerebral infarction, 24(38.1%) with cerebral hemorrhage, and 11(17.5%) with subarachnoid hemorrhage. In terms of size of lesion, they were divided into 29(46.0% with less than tan 1cm, 15 (23.8%) with $1{\sim}2cm$ and 19(30.2%) with longer than 2cm. Thirty-five patients(55.7%) reported paralysis in their right side, while 28(44.8%) complained paralysis in their left side. No recidivation was reported by 51(81.1%) while recidivation was asserted by 12(19%). Among them, 27(42.9%) had no past history but 36(57.1%) had such. 3. Regarding the time hour onset to admission to physical therapy, 46patients(73.0%) experienced it for less than one month, while 17(27.0%) for longer than one month. In terms of period of physical therapy, 30(47.6%) underwent the therapy for less than one month, 18(28.6%) for 1-2 months and 15(23.8%) for longer than 2 months. As is shown in the above study, the longer the period of physical therapy is, the more changes might occur in points of MMSE-K and MMAS. It may, therefore, be concluded that sufficiently longer period of physical therapy ensures the increased recovery of physical functions from stroke.

Preceding infection or inflammation such as bacterial meningitis has been associated with poor outcomes after stroke. Previously, we reported that intracorpus callosum microinjection of lipopolysaccharides (LPS) strongly accelerated the ischemia/reperfusionevoked brain tissue damage via recruiting inflammatory cells into the ischemic lesion. Simvastatin, 3-hydroxy-3-methylgultaryl (HMG)-CoA reductase inhibitor, has been shown to reduce inflammatory responses in vascular diseases. Thus, we investigated whether simvastatin could reduce the LPS-accelerated ischemic injury. Simvastatin (20 mg/kg) was orally administered to rats prior to cerebral ischemic insults (4 times at 72, 48, 25, and 1-h pre-ischemia). LPS was microinjected into rat corpus callosum 1 day before the ischemic injury. Treatment of simvastatin reduced the LPS-accelerated infarct size by 73%, and decreased the ischemia/reperfusion-induced expressions of pro-inflammatory mediators such as iNOS, COX-2 and IL-$1{\beta}$ in LPS-injected rat brains. However, simvastatin did not reduce the infiltration of microglial/macrophageal cells into the LPS-pretreated brain lesion. In vitro migration assay also showed that simvastatin did not inhibit the monocyte chemoattractant protein-1-evoked migration of microglial/macrophageal cells. Instead, simvastatin inhibited the nuclear translocation of NF-${\kappa}B$, a key signaling event in expressions of various proinflammatory mediators, by decreasing the degradation of $I{\kappa}B$. The present results indicate that simvastatin may be beneficial particularly to the accelerated cerebral ischemic injury under inflammatory or infectious conditions.

Clinical observation was done on 272 cases of patients who were diagnosed as CVA with brain CT, TCD, MRI scan and clinical observation. They were hospitalized in the oriental medical hospital of Kyung-Won University from 1st January to 31st December in 1997. 1. The cases were classified into the following kinds: cerebral infarction, cerebral hemorrhage. and transient ischemic attack. The most case of them was the cerebral infarction. 2. There is no significant difference in the frequency of strokes in male and female. And the frequency of strokes was highest in the aged over 50. 3. In cerebral infarction the most frequent lesion was the territory of middle cerebral artery, and in cerebral hemorrhage the most frequent lesion was the basal ganglia. 4. The most ordinary preceding disease was hypertension. and the next was diabetes. 5. The rate of recurrence was high in cerebral infarction. 6. The cerebral infarction occurred usually in resting and sleeping, and the cerebral hemorrhage in acting. 7. The common symptoms were motor disability and verbal disturbance. 8 The average time to start physical therapy was 1l.3rd day after stroke in cerebral infarction and it was 15.2th day after stroke in cerebral hemorrhage. 9. The common complications were urinary tract infection, pneumonia, myocardial infarction. 10. Hypercholesterolemia and hypertriglyceridemia are usually found more frequently in cerebral infarction than in hemorrhage. 11. In acute or subacute stage, the methods of smoothening the flow of ki(順氣), dispelling phlegm(祛痰), clearing away heat(淸熱) or purgation(瀉下) were frequently used. and in recovering stage, the methods of replenishing ki(補氣), tonifying the blood(補血) or tranquilization(安神) were frequently used.

The Kernohan-Woltman notch phenomenon (KWNP) refers to an intracranial lesion causing massive side-to-side mass effect which leads to compression of the contralateral cerebral peduncle against the free edge of the cerebellar tentorium. Diagnosis is based on "paradoxical" motor deficit ipsilateral to the lesion associated with radiologic evidence of damage to the contralateral cerebral peduncle. To date, there is scarce evidence regarding KWNP associated neuroimaging patterns and motor function prognostic factors. A systematic review was conducted on Medline database from inception to July 2021 looking for English-language articles concerning KWNP, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The research yielded 45 articles for a total of 51 patients. The mean age was 40.7 years-old and the male/female sex ratio was 2/1. 63% of the patients (32/51) suffered from head trauma with a majority of acute subdural hematomas (57%, 29/51). 57% (29/51) of the patients were in the coma upon admission and 47% (24/51) presented pupil anomalies. KWNP presented the neuroimaging features of compression ischemic stroke located in the contralateral cerebral peduncle, with edema in the surrounding structures and sometimes compression stroke of the cerebral arteries passing nearby. 45% of the patients (23/51) presented a good motor functional outcome; nevertheless, no predisposing factor was identified. A Glasgow coma scale (GCS) of more than 3 showed a trend (p=0.1065) toward a better motor functional outcome. The KWNP is a regional compression syndrome oftentimes caused by sudden and massive uncal herniation and leading to contralateral cerebral peduncle ischemia. Even though patients suffering from KWNP usually present a good overall recovery, patients with a GCS of 3 may present a worse motor functional outcome. In order to better understand this syndrome, future studies will have to focus on more personalized criteria such as individual variation of tentorial notch width.

Objectives : The water extract of Sopung-tang (SPT) has been traditionally used in the treatment of acute stroke in Oriental Medicine. Pro-inflammatory cytokines play a critical role in the onset of post-ischemic inflammatory cascades. The present study was designed to investigate the effects of SPT on pro-inflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : After SPT oral administration to the mice for five days, with using Rose Bengal and cold light, photothrombotic ischemia lesion was induced in stereotactically held male BALB/c mice. Also, results including, gross finding lesion size, histopathological finding changes, and inflammatory cytokine expression changes from the photothrombotic ischemia mouse model were observed. Results : The photothrombotic ischemia lesion was decreased by the oral injection of SPT. Also, SPT inhibited the expression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, the active form of caspase-3 protease, and transglutaminase-2 in the photothrombotic ischemia lesion. Conclusions : These results suggest that SPT protects the ischemic death of brain cells through suppression of the production of anti-inflammatory cytokines and catalytic activation of caspase-3 protease in the photothrombotic ischemia mouse model.

The purpose of this study was to establish reproducible ischemic infarction model using allogenic blood clot in beagle dogs and identify induced ischemic lesion after middle cerebral artery occlusion using magnetic resonance imaging (MRI) and histopathologic findings. Twenty eight male beagle dogs with no evidence of neurologic disease were experimented. Allogenic embolus was made using a healthy beagle dog. After internal carotid artery (ICA) was exposure, 16G catheter was introduced through the ICA. The dog was administered 0.3 ml blood clot for 15 seconds followed by 3 ml of saline for 15 seconds. MRI scans were performed with 1.5T to evaluate ischemic lesion at 7 days after middle cerebral artery occlusion procedure. Evaluation parameters of MRI include location, distribution, infarction type, margin, shape, mass effect and intensity of T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), fluid attenuated inversion recovery (FLAIR) sequence, diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC). On MRI, all dogs (28/28) showed focal or multifocal lesion including telencephalon and thalamus lesions, especially caudate nucleus (24/28). These lesions had well-defined margin from adjacent brain parenchyma, none or mild mass effect and various shape. Most of dogs appeared hyperintensity on T1WI, T2WI, FLAIR, and DWI/ADC, corresponding to chronic infarction. These lesions were histopathologically confirmed atrophic changes and unstained lesion. In conclusion, MRI is the useful method to provide information about ischemic infarction in dogs and the best reproducible ischemic infarction model was developed by using allogenic blood clot.

Background : Vascular dementia occurs mainly due to cerebral vascular disease. So we performed this clinical study to investigate the incidence and characteristics of vascular dementia in stroke patients. Methods : This study was performed on the patients hospitalized from April 1, 1998 to August 31, 1998 at the department of circulatory internal medicine, hospital of Oriental medicine, Kyung-Hee University, and diagnosed cerebral infarction or hemorrhage by Brain CT or MRI. we devided the patients into two groups; vascular dementia group and non dementia group according to MMSE-K(Mini Mental State Examination Korean version), Hasegawa dementia scale. Patients were diagnosed dementia using DSM-IV. We compared general characteristics, stoke types and laboratory findings between the two groups and investigated the correlationship between MMSE-K and Hasegawa dementia scale. Results : Results showed that the incidence of vascular dementia was about 27.8% in stroke patients. The greater number of subjects with dementia were women in the lower educational classes and had lower MBI(Moderfied Bathel Index) scores. Vascular dementia were more common in patients with large brain lesion size($>20cm^3$). There was a positive correlationship between Hasegawa scores and MMSE-K.
