Excitatory amino acids have been implicated as one of the important putative cellular toxins in ischemic brain. Ketamine antagonizes the excitotoxic action of excitatory amino acids in the central nervous system. The present study was undertaken to determine whether ketamine anesthesia protect the formation of brain edema in the model of focal cerebral ischemia in rats. Forty adult male Sprague-Dawley rats weighing between 300gm and 400gm were used in this study. The animals were anesthetized with either halothane or ketamine, and then right middle cerebral artery occlusion were performed. After 4 hours of ischemia, the brain water and ion contents(Na+ and K+) were determined in the central, intermediate, and outer zones of each cortical mantle. In both halothane and ketamine anesthetized groups, there were significant brain edema in the ischemic central and intermediate zones. Ionic shifts were also observed in the ischemic central and intermediate zones to approximately same extent as the brain water content in both groups. However, there were no significant differences of brain edema between the two groups in the corresponding ischemic zones. These results suggest that ketamine anesthesia does not have significant protective effect on the formation of brain edema during the early stages of permanent incomplete cerebral ischemia.

The purpose of this study was to investigate the level of anxiety for the mothers of leukemic children and to provide the fundamental data for the better performance of caring to them. The subject were 292 mothers : 100 mothers whose children had a leukemia, 80 mothers whose children had taken a tonsillectomy, 112 mothers whose children with medical disease except cancer. The data were collected through the state-Trait Anxiety Inventory of Spilberger and analyzed by t-test, ANOVA, Scheffe test. The results were as follows ; 1. The state anxiety mean score of mothers with leukemic children was 54.16. 2. The state anxiety of mothers with leukemic children was higher than that of the rest (F=8.00, P=0.0004). 3. There was no significant difference in anxiety of mothers with leukemic children in relation to leukemic children's and their mother's general characteristics.

The intramedullary glioma of spinal cord has occupied 22.5% of intraspinal neoplasm, and is the most common among the intramedullary spinal cord tumor, and the first successful operative removal was performed in 1907 by Elsberg. The intramedullary astrocytoma has frequent incidence in the thoracic and cervical region of the spinal cord, which has more frequent grade I astrocytoma. We experienced a case of intramedullary grade II astrocytoma of the thoracolumbar region which has associated a paraplegia as neurological deficit. A 26 year old Korean female has admitted to our clinic because of paraplegia with incontinence for 2 years. On admission, the neurological examination revealed a paraparesis below T12 level with urinary and fecal incontinence and then local tenderness from T10 to L1 level. The simple X-ray film of the thracolumbar spine has showed erosion of both pedicle, widening of interpeduncular distance and scalloping change of posterior vertebral margin from T12 to L1, which were similar to the picture of intramedullary spinal cord tumor. We performed a myelography by pantopaque through the lumbar and cisternal puncture for accurate site of lesion, and found a complete block at L1 level and T10 level on myelogram. Then the immediate total laminectomy from T8 to L1 was applied. The operative finding was a intramedullary mass with cystic fluid, which has compressed the spinal cord. After aspiration of cystic fluid, we removed the tumor mass incompletely because of intermingling with spinal cord but the decompression was enough. The neurological defict was improved gradually for post-operative 4 weeks, thereafter improvement was stopped and remained the paraparesis. The post-operative pathological diagnosis was grade II astrocytoma, which composed of anaplastic cell and radiotherapy has followed.
