This study was carried out to find out changes in regional cerebral blood flow(r-CBF) in relation to(i) clinical status of patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms ; (ii) the degree of subarachnoid hemorrhage as indicated by brain CT scanning ; (iii) the severity of angiographic vasospasm, and (iv) other neuropathological condition. Measurement of r-CBF were performed, using 133Xe inhalation method, on 50 patients with ruptured intracranial aneurysms. Some of the major findings were as follows : 1) The degree of abnormalities of blood flow correlated well with the clinical severity of neurological deficits. 2) A marked reduction in r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF decreases below 30ml/100gm/min in almost all of the patients, and severity of vasospasm correlated with the decrease of CBF. 4) The measurement of CBF on patients with subarachnoid hemorrhage was thought to the useful for foreseeing the clinical outcome of the patients.

Recent technological advances in ultrasound instrumentation have resulted in equipment that will image in "real-time" slices of the human brain similar in quality to computerized tomography(CT). Multiple authors have attested to its usefulness in locatin, characterizing, and facilitating in the biopsy or removal, or both, of intracerebral masses. In this study, the author has examined the efficacy of intraoperative neurosurgical ultrasound in 18 patients who were admitted to the Department of Neurosurgery, Kyung Hee University Hospital. The results were as follows : 1) It can provide critical assistance in precise localization of subcortical masses, since in many instances the overlying surface of brain provides no clue for localization. 2) This technique is very useful for the identificantion of deep lesions, provding infromation about their solid and cystic components and about the shortest route of access to tumor. 3) It provides precise information to help guide biopsy needles into deep lesions, and to confirm their presence within the lesion itself. 4) The system is highly accurate in visualizing ventricular catheters during and after their placement. 5) The system is inherently safe for the patient and the operating room personnel since there is no radiation exposure.

BACKGROUND: It is reported that abnormal eating behavior is more frequent in the group of weight control than those of no control. Repeated and chronic binge eating behavior has associations with impaired work and social functioning, overconcerns with body shape and weight. The purpose of this study is to investigate the degree of abnormal eating behavior according to weight management, depression level and obesity. METHODS: From June 1999 to July 1999, we collected self record questionnaire including body mass index(BMI), Beck Depression Inventory(BDI), Eating Attitude Test(EAT) from 1292 students of one girl's high school in Seoul. Study subjects were divided by BMI, the set point was 25 kg/m2. EAT score associated with weight control, BMI, BDI, smoking and alcohol was assessed by multiple linear regression. Study subjects were also grouped by the existence of the history of weight management behavoir, then BMI, EAT score and BDI in each subgroups was assessed by t test. RESULTS: Obese students were 42, whereas those of BMI under 25 kg/m2 were 1191. BDI score ranging from 5 to 20 were 940, 21 to 63 were 179. The EAT score has significant relevance to the history of weight control, BMI, and BDI score in order. The EAT score and BMI were higher in the subjects who experienced various modes of weight control (48.41+/-14.47 vs 33.63+/-12.52 in EAT, 20.34+/-2.26 vs 18.72+/-1.89)(p<0.01). CONCLUSION: EAT score was associated with weight control, BMI and BDI. EAT score and BMI were higher in weight control samples.

Subenpendymal giant cell astrocytoma is a rare cerebral glioma that mainly occurs in patients with tuberous sclerosis. In the following case, a subependymal giant cell astrocytoma in the absence of tuberous sclerosis occurred in the wall of the lateral ventricle and presented as an intraventricular mass cauing hydrocephalus by obstruction of the foramen of Monro. The mass was removed completely through transcallosal approach with the microsurgical technique.

The authors analyzed 105 cases of spinal cord tumor in regarding to the age, sex, location and distribution, clinical presentation and postoperative outcome. They were confirmed by pathologic study at the Kyung Hee Medical Cented from 1981 to 1991. The incidence of spinal cord tumors was slightly predominant in males. The most commom tumor was neurogenic tumor. The neurogenic tumor composed 43.8%(46 cases), and the rests were meningioma 15.2%(16 case), metstasis 10.5%(11 cases) and others. The tumor were located most frequently in the thoracic area(31.4%) and in the intradural extramedullary space(56.1%). Most common initial symptom of spinal cord tumors were pain and it's mean duration was 8.3 month. The patients were assigned to one of four groups according to their neurologic deficit. About 66.6%(70 cases) of the patients were included in Groups I and II(mild neurologic deficit), and others were classified in Groups III and IV(significant to severe neurologic deficit). Complete tumor removal was achieved in 70.4%(4 cases) of the patients, and subtotal removal was performed in 26.7%(28 cases), and biopsy was performed in 2.9%(3 cases). Among the 105 patients, the postoperative outcomes on dischage were recovery in 36 cases(34.3%), improved in 45 cases(42.9%), stationary state in 12 cases(11.4%), and progression in 12 cases(11.4%).

Two patients with basilar bifurcation aneurysm were treated by different approach, low lying posteriorly projecting aneurysm was clipped with subtemporal approach and high bifurcated basilar bifurcation aneurysm with multiplicity approached through pterional method. The author reviewed literature concerning the approaches of basilar bifurcation aneurysm.
