Subependymal Giant Cell Astrocytoma in the tuberous Sclerosis.: Jin Han Park, Seong Ho Kim, Dong Ro Han, Jang Ho Bae, Sam Kyu Ko, Oh Lyong Kim, Byung Yon Choi, Soo Ho Cho; Yeungnam Univ J Med. 1994;11(2):221-229. Published online December 31, 1994; DOI: https://doi.org/10.12701/yujm.1994.11.2.221

Abstract PDF: Tuberous sclerosis is reported rarely and is associated with systemic lesions including central nervous system, skin, heart, eye and kidney. Approximately 5-15% of individuals with tuberous sclerosis will develop brain neoplasia, almost invariably subependymal giant-cell astrocytoma (SGCA). We experienced a case of SGCA with tuberous sclerosis operated by the transcallosal approach and report with literature review.

The Effects of Microwave Irradiated on Rabbit's ICP.: Jin Han Park, Seong Ho Kim, Dong Ro Han, Jang Ho Bae, Oh Lyong Kim, Byung Yon Choi, Soo Ho Cho, Joon Ha Lee; Yeungnam Univ J Med. 1994;11(2):213-220. Published online December 31, 1994; DOI: https://doi.org/10.12701/yujm.1994.11.2.213

Abstract PDF: Damages on central nervous system induced by the exposure of microwave. However, the effects of microwave on ICP are not studied yet. The ICP affected by the condition of the condition of the brain has an significant effect on vital sign. So we investigated the changes of ICP of the rabbits after exposure. Twenty four rabbits were divided into 3 groups depending on the amount of exposure to microwave. One group was composed with 8 rabbits were exposed to microwave for 10 miniutes. Other were composed to microwave for 20 miniutes, 30 miniures, respectively. Intracranial pressure on each group were measured by subdural type ICP monitoring catheter immediately, first day, 3rd day, 5th day and 7th day after exposure of microwave. Results indicates that intracranial pressure of rabbits are not affected with statistical significance by exposure of microwave.

Effects of the Selective Management for Increased Intracranial Pressure with Obstruction of Internal Carotid Artery in Rabbits.: Bum Dae Kim, Kyoung Yeob Lee, Seong Ho Kim, Dong Ro Han, Jang Ho Bae, Oh Lyong Kim, Byung Yon Choi, Soo Ho Cho, Hyoun Jin Shin; Yeungnam Univ J Med. 1994;11(1):167-180. Published online June 30, 1994; DOI: https://doi.org/10.12701/yujm.1994.11.1.167

Abstract PDF: In order to inquire the most-effective management of increased intracranial pressure(ICP), mannitol, steroid and hyperventilation were used in rabbits after ligation or non-ligation of the carotid artery. Mannitol was more effective than steroid and hyperventilation in the degree of the reduction of ICP. The intracranial pressure was decreased 43~45% for 25~30 minutes after injection of mannitol. Steroid was less effective than mannitol in the degree of the reduction of ICP. But the time of reduction of ICP was longer, that is, the degree of reduction was 24~60 minutes after injection of steroid. Hyperventilation is effective in the initial time only, for 10 minutes after hyperventilation. The degree of ICP reduction was 13.5~16.7 % for 10 minutes after hyperventilation. The combined group, that is three kinds of mangenent were used, is the most effective treatment to reduce ICP of ICP. The degree of the reduction of ICP was 42.1~49.3% for 20 minutes, 47.7~52.5% for 30minnutes. There was no significant difference between and non-ligation group.

Astrocytoma in the Bilateral Thalamus: A Case Report.: Eul Soo Chung, Jang Ho Bae, Dong Ro Han, Eun Sik Doh, Oh Lyong Kim, Yong Chul Chi, Byung Yearn Choi, Soo Ho Cho; Yeungnam Univ J Med. 1990;7(2):167-172. Published online December 31, 1990; DOI: https://doi.org/10.12701/yujm.1990.7.2.167

Abstract PDF: Astrocytoma in the thalamus in not so frequent in incidence (1%). Moreover, bilateral thalamic tumor is rare. Certain tumors of the thalamus are considered resectable but most of thalamic tumors are thought to be untouchable. Bilateral thalamic astrocytoma with hydrocephalus was diagnosed by stereotactic biopsy and ventriculoperitoneal shunt operation was done with result of improvement. We report a case of astrocytoma in the bilateral thalamus with literature review.

Expansive Laminoplasty for Cervical Compression Myelopathy.: Dong Ro Han, Eun Sig Doh, Oh Lyong Kim, Yong Chul Chi, Byung Yearn Choi, Soo Ho Cho; Yeungnam Univ J Med. 1989;6(2):141-146. Published online December 31, 1989; DOI: https://doi.org/10.12701/yujm.1989.6.2.141

Abstract PDF: In an attempt to eliminate some negative aspects of conventional extensive laminectomy, 4 cases of multiple level of cervical compression myelopathy, 1 OPLL (ossification of posterior longitudinal ligament) and 3 cervical stenosis, were treated with a technique of expansive laminoplasty. Operative results in all patients were satisfactory without surgical complications and all patients had a neurological improvement. We suggest that our technique is more effective one for cervical canal stenosis, OPLL, and spondylosis than conventional extensive laminectomy.
