Objective : We investigated the expression of hippocampal heat shock protein 70 (HSP-70) infarction volume after different durations of experimental ischemic stroke in mice. Methods : Focal cerebral ischemia was induced in mice by occluding the middle cerebral artery with the modified intraluminal filament technique. Twenty-four hours after ischemia induction, both hippocampi were extracted for HSP-70 protein analyses. Slices from each hemisphere were stained with 2,3,5-triphenyltetrazolium chloride (2%), and infarction volumes were calculated. HSP-70 levels were evaluated using western blot and enzyme-linked immunosorbent assay (ELISA). HSP-70 subtype (hsp70.1, hspa1a, hspa1b) mRNA levels in the hippocampus were measured using reverse transcription-polymerase chain reaction (RT-PCR). Results : Cerebral infarctions were found ipsilateral to the occlusion in 10 mice exposed to transient ischemia (5 each in the 30-min and 60-min occlusion groups), whereas no focal infarctions were noted in any of the sham mice. The average infarct volumes of the 2 ischemic groups were $22.28{\pm}7.31mm^3$ [30-min group${\times}$standard deviation (SD)] and $38.06{\pm}9.53mm^3$ (60-min group${\times}$SD). Western blot analyses and ELISA showed that HSP-70 in hippocampal tissues increased in the infarction groups than in the sham group. However, differences in HSP-70 levels between the 2 infarction groups were statistically insignificant. Moreover, RT-PCR results demonstrated no relationship between the mRNA expression of HSP-70 subtypes and occlusion time or infarction volume. Conclusion : Our results indicated no significant difference in HSP-70 expression between the 30- and 60-min occlusion groups despite the statistical difference in infarction volumes. Furthermore, HSP-70 subtype mRNA expression was independent of both occlusion duration and cerebral infarction volume.

Clinical observation was done on 290 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 1996. 1. The cases were classified into the following kinds : cerebral infarction, cerebral hemorrhage, and transient ischemic attack. The most case of them was the cerebr진 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 frequency of strokes seems to have no relation to the season. 7. The cerebral infarction occurred usually in resting and sleeping, and the cerebral hemorrhage in acting. 8. The course of entering hospital, most patients visited this hospital as soon as CVA occurred. And the half of patient visited this hospital within 2 days after CVA attack. 9. In the cases of patients who were unconscious at the admission, the prognosis was worse than that of the alert patients. 10. The common symptoms were motor disability and verbal disturbance. 11. The average duration of hospitalization was 27.4 days, and in case of cerebral hemorrhage the duration was prolonged. 12. The average time to start physical therapy was 13.3rd day after stroke in cerebral infarction and it was 19.9th day after stroke in cerebral hemorrhage. 13. The common complications were urinary tract infection, pneumonia, myocardial infarction and so on. 15. At the time of entering hospital, in most cases the blood pressure was high, but blood pressure was well controlled at the time of discharge. 16. Generally reported, hypercholesterolemia and hypertriglyceridemia are usually found in cerebral infarction. But in this study, they were found more frequently in cerebral hemorrhage than in infarction. 17, In the most cases, western and oriental medical treatments were given simultaneously. 18. 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.

This study was done to examine the risk factors between controls group and acute brain infarction patients group, and to compare high risk group with low risk group through NIHSS(National Institutes of Health stroke scale). We compared the risk factors between acute brain infarction patients group(N=180) and controls group(N=93). And according to risk factors, we analyzed 1st NIHss, after 3 weeks improved extent within acute brain infarction patients group. The results were as follows. 1. Among the risk factors, HTN, DM, the blood levels of HCY were significantly higher and the blood levels of HDL-C was significantly lower in patients group than controls group. 2. In scale analysis according to risk factors, 1st NIHss were significantly higher in Hypo-HDL-cholesterolemia, Obesity, High-Homocysteine, HTN, DM, previous CVA history group than low risk group within acute brain infarction patients group. 3. In after 3 weeks improved extent analysis according to risk factors, improved extent were lower in Hyperlipidemia, HTN, DM, previous cardiac history, older age group than low risk group within acute brain infarction patients group. The above results suggest that significant risk factors of acute brain infarction, and shows the High risk group that had risk factor of brain infarction recognized from the former research tends to have higher 1st NIHss. Also the High risk group tends to have lower improved extent, but the results are not statistically significant. Furthur research on subject is needed.

This study was undertaken to investigate the effects of n-6(corn oil) & n-3(fish oil) fatty acids on infarction size and the cerebral activities of antioxidant enzyme in rat focal brain ischemia model. Weaning Sprague-Dawley rats were fed with either corn oil supplemented diet(COD, 14% corn oil) or fish oil supplemented diet(FOD, 14% menhaden oil) for 6 weeks. The right middle cerebral artery was occluded for 2 hours with a silicon rubber coated nylon surgical thread. After 24 hours of recirculation, the rats were sacrificed and brain sections were photographed using CCD camera after staining with 2, 3, 5-triphenyltetrazolium chloride for 60 minutes in room temperature. The infarcted area was measured and the volume of infarction was calculated. Catalase(CAT), superoxide dismutase(SOD) activities, and fatty acid composition in the brain were also measured. The total and corrected infarction volumes were not significantly different between FOD and COD group. The docosagexaenoic acid(DHA) and DHA content/arachidonic acid(AA) ratio of the cerebral cortex, an index of defense against lipid oxidation, were significantly increased in FOD group compared to those of COD group(p<0.05). In the left cortex(non-infarction side) as well as the right cortex(infarction side) of FOD group, CAT and Cu/Zn SOD activities were higher than those of the COD group(p<0.05). However, CAT and Cu/Zn SOD activities were not significantly different between the left cortex(non-infarction side) and the right cortex(infarction side) of both FOD and COD group. GPx activities were also not significantly different between two groups. Our results demonstrate that the brain infarction size in FOD and COD were not significantly different. However, cerebral lipid composition and antioxidant enzyme activities in FOD and COD group were different. Fish oil, a source of n-3 polyunsaturated fatty acid(PUFA) and corn oil, that of n-6(PUFA) may have a protective effect against oxidative stress induced via different mechanisms.

1. Purpose : The purpose of this study was done to compare the sex, past history, hematologic relationship between the Cerebral infarction patients and the Cerebral hemorrhage patients. 2. Methods : We selected the two study groups. The one is 20 Cerebral infarction patients and the other 20 Cerebral hemorrhage patients with confirmed by Brain CT or MRI. We made an investigation into past history. We examined and made a comparative study of CBC, LFT, Na, K, Cl in the both group. 3. Result & Conclusion : In the Cerebral hemorrhage group, there were many patients with Hypertension and Diabetes mellitus than the Cerebral infarction group. In the Cerebral infarction group, there were many patients with abnormal RBC count with no significant. Also, ESR is higher than the other group. Between the Cerebral infarction and the other group, we discovered significant cases with abnormal triglyceride, ALP in the Cerebral infarction group(p<0.05). Abnormal triglyceride is known one of important risk factor of Cerebral infarction, but this study was significant in the Cerebral hemorrhage group. Also, ALP was significant in the Cerebral hemorrhage group. Therefore more extensive research is needed.

Objectives : Pituitary apoplexy is a well-described clinical syndrome resulting from pituitary hemorrhage, hemorrhagic infarction, or infarction, almost invariably occurring in the presence of an adenoma. We analyzed pituitary apoplexy with an emphasis on clinical presentation, pathology and predisposing factors. Methods : We reviewed 35 histologically proven pituitary adenomas, operated from January 1995 to August 1999, to select 8 cases which showed clinical or operative findings compatible with pituitary apoplexy. These patients were analyzed in terms of symptom and sign, hormonal status, and predisposing factors, pathologic findings. Results : Among 35 surgically treated tumors of the pituitary gland, 8 cases(23%) were diagnosed as pituitary apoplexy. The pathologic findings revealed hemorrhage(7 cases) and infarction(1 case) of pituitary adenomas. One case had predisposing factor of appendectomy. The most common presenting symptom and sign were sudden severe headache and visual disturbance. Conclusion : We treated pituitary apoplexy surgically and obtained good outcomes. Pituitary apoplexy due to massive infarction of the pituitary gland is very rare condition but surgical treatment by trans-spheniodal surgery showed a good result.
