Objective : The aim of this study was to investigate the neuroprotection effect of estrogen on brain atrophy following cerebral infarction. Method : All animals in this study were classified into 4 groups; ovariectomy group (OVXgroup), cerebral infarction group (INF group), combination ovariectomy and cerebral infarction group (OVX + INF group), and naturally intact group for control data (NOR group). Cerebral infarction was made by Chen's method with some modification. Ovariectomy was performed by Wayforth's method. Experimental data for each group was collected at 15 days, month, 3 months, and 6 months after starting observation. Serum $17{\beta}-estradiol(E2)$ was determined by radioimmunoassay. Brain volume was measured and calculated with image analysis. Each brain was sliced at intervals of 2mm in chamber after 30 min of freezing in refregerater. Cerebral volume was obtained by sum of volume of each slice level, which was mean $area{\;}{\times}{\;}2mm$. Results : Cerebral ischemia was found to decrease the serum concentration of $17{\beta}-{\;}estradiol(E2)$ and to inhibit the physiologically conpensatary function of the ovariectomized rats. Also we found that deprivation of estrogen have resulted in more severe cerebral atrophy followed by cerebral infarction. Conclusion : It is suggested that estrogen has a neuroprotection effect on cerebral atrophy following cerebral infarction.

Cerebral infarction rarely occur following head injury. The authors present the case of a 39-year-old man with complete infarction in the middle cerebral artery[MCA] and anterior cerebral artery[ACA] territories ccurred immediately after head injury. He had compound depressed fracture in right frontal bone with no neurological deficit. After the depressed bone elevation, postoperative computed tomography scan showed the right MCA and ACA territory infarction with midline shift. Cerebral angiography obtained on the day after emergent decompressive craneictomy showed the complete occlusion of the internal carotid artery[ICA] at the level of lacerum ICA segment. There was no evidence of neck vessel dissection and basal skull fracture. Cerebral infarction can occur in an ultraearly period after head injury without neck vessel dissection or basal skull fracture. We stress the need for attention to the cerebral infarction as the cause of a rare neurological deterioration of the head trauma.

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-${\alpha}$, 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 $20{\mu}g/mL$ or less. Western blot of BV2 cells, treated with 0.625, 1.5, $2.5{\mu}g/mL$ of SV, showed a significant decrease in the expression of p-IkB-${\alpha}$, 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.

Background and Purpose : To prevent ischemic cerebral infarction, it is very important to reduce risk factors which might cause stroke. However, the relationship of coffee consumption with ischemic cerebral infarction still remains unclear. The purpose of this study was to investigate the effects of coffee consumption on the risk of ischemic cerebral infarction in Koreans. Methods : A case-control study was conducted from April 1, 2001 to July 31, 2004. Cases (n=435) of first incident ischemic cerebral infarction were enrolled and were mostly matched by age to stroke-free hospital controls (n=407). All subjects were interviewed, examined and had anthropometric measurements by using an organized questionnaire. The coffee consumption was classified by the average frequency of intake, being none, 1 cup/day, 2-4 cups/day, more than 5 cups/day. Odds ratios (ORs) of ischemic cerebral infarction were proved multivariate analysis after adjustment for demographic factors, diet factors, and vascular risk factors. Results : When adjusted for sex, age, and other factors, coffee consumption and stroke do not have a significant association. (${\leq}$ cup/day OR=1.035, 95% CI=0.880-2.756; 2-4cups/day OR=1.452, 95% CI=0.864-2.440; ${\geq}$ 5 cups/day OR=1.557, 95% CI=0.705-3.435) Conclusions : In this study, we conclude that coffee consumption is not an important risk factor of ischemic cerebral infarction in Koreans. Prospective and cohort study on the relation between coffee consumption and the possibility of inducing ischemic cerebral infarctions in Koreans will be required in the future.

Objectives : There is continuing controversy about the benefits of decompressive craniectomy in massive cerebral edema following space occupying hemispheric cerebral infarction. The aims of this study are to determine the effectiveness and to confirm the life-saving nature of decompressive craniectomy with dural augmentation for massive cerebral infarction. Patients and Methods : We present twelve patients with medically uncontrollable hemispheric cerebral infarction. All were treated with extensive craniectomy and duroplasty without resection of necrotic tissue. We evaluated various characteristics(size of hemispheric infarction, Glasgow Coma Scale, volume of low density and midline shift in CT) at three different periods(preoperative, immediate postoperative and 3-4weeks after operation) and evaluated effectiveness of hemicraniectomy for massive cerebral edema after large hemispheric infarction. Results : All patients have survived from surgery. Nine patients with nondominant hemispheric infarction showed significant functional recovery with minimal assistance, and remaining two patients with dominant hemispheric infarction and one patient with nondominant hemispheric infarction have functionally dependent. The volume of low density and midline shift in CT were significantly reduced after decompressive craniectomy. Conclusions : Our results indicate that decompressive craniectomy with dural augmentation without resection of necrotic tissue for massive cerebral hemispheric infarction not only reduce the mortality and infarction size but also significantly improve the outcome, especially for nondominant hemispheric infarction.

In a 36-month period, 23 selected Patients with Acute Cerebral Infarction were studied utilizing Computerized Tomography, Barthel Index in an attempt to correlate Brain Computerized Tomography findings with 1week, 4weeks rehabilitation and evaluate the influences of the size and location of the lesion. The study suggested that the size of the lesion had impact on 4 weeks rehabilitation. There was significant different between the patients with Middle Cerebral Artery Pial Territory Infarction(I.P.B.M.C.A.) lesion and the patients with Lacunar Infarction(L.I.), Striatocapsular Infarction(S.C.I.), Internal Watershed Infarction(I.W.I.) lesion, but there was no significant difference between the patients with L.I. lesion and the patients with S.C.I. lesion and the patients with I.W.I. lesion. The size and location of the lesion should be considered together in predicting the functional outcomes of Acute Cerebral Infarction.

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.

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.
