Objective : Controversy exists which surgical treatment better in lumbar grade I spondylolisthesis, decompressive laminectomy with or without lumbar instrumentation. Methods : Out of Sixty-four patients with lumbar spondylolisthesis underwent surgery, 18 patients operated with decompressive laminectomy alone and 44 patients with decompession and lumbar instrument, during recent 5-years between January, 1994 and December, 1998. The author studied a long term follow-up in the above two groups to analyzing the overall clinical outcomes in each group and to determining the incidence of pos-toperative radiologic instability. Results : 1) Overall postoperative symptoms improvement were not so different in both groups. 2) Postoperative progressive subluxation is more common after decompressive laminectomy without instrumentation than with instrumentation group. 3) Overall clinical outcomes were slightly better in decompressive laminectomy without instrumentation than with instrumentation group but there was no significant difference. 4) Postoperative radiologic changes did not seem to influence the patient-reported clinical outcomes. 5) Postoperative complications is more common in decompressive laminectomy with instrumentation group than without instrumentation group. Conclusion : In the surgical management of grade I spondylolisthesis, the efficiency and superiority of surgical treatments requires the cost effectiveness and risk/benefit analysis of decompressive laminectomy with or without instrumentation. Therefore, Further detailed studies of long term follow up in a large number of patients in each group are needed for choice of best treatment.

The authors report two cases of familial hemifacial spasm according to the clinical and three dimensional shortrange magnetic resonance angiography(3D-SRMRA) findings. In the family of the first case, there were five patient's with acquired hemifacial spasm in successive generations. Three male and two female patients in successive generations of the same family developed acquired hemifacial spasm. Four patients were on the left side and one was on the right side. In the family of the second case, there were three patient's with acquired hemifacial spasm in successive generations. Two brothers developed left-sided hemifacial spasm. 3D-SRMRA finding of the probands demonstrated that both anterior inferior cerebellar artery in first case and anterior inferior cerebellar artery & vertebral artery in second case offend the 7th cranial nerve respectively. The presence of familial clustering of these rare disorders suggest an underlying genetic predisposition. All family pedigrees suggest that a pattern of autosomal-dominant inheritance with partial penetrance.

The main purpose of this paper is to discuss the phenomena of the deletion and ellipsis of an anaphoric one. Chapter II deals with the deletion of an anaphoric one substituting an uncountable NP, and relates to the syntactic structural analysis of the deletion of an anaphoric one occurring after a cardinal number. Chapter III discusses a specific syntactic structure of the requirement deletion or the optional characteristics about an ellipsis of an anaphoric one. In the conclusion, this study shows that all the statements above have been explained according to the grammatical properties. (Kyungnam University)

The main purpose of this paper is to analyze and discuss all the syntactic structure phenomena occurring in deletion and ellipsis in the English comparative sentence. Two interrelated different aspects of deletion and ellipsis in the English comparative sentence have been described under the following topics: (1) Deletion in the Comparative Clause (2) Difference between Deletion and Ellipsis in the Comparative Construction. In Chapter II, we have provided the outlines of discrimination and the syntactic frameworks of deletion and subdeletion and ellipsis in the English comparative construction. In Chapter III, we have made some differences of deletion from ellipsis in the comparative construction according to the properties reflecting syntactic structures. We could attain our goals of examining the results of the following topics: (1) the basic concept of deletion and ellipsis (2) ellipsis types in the comparative sentence (3) ellipsis constraints in the comparative clause (4) coordinate structure reduction and comparative ellipsis. In conclusion, this paper has discussed some differences between deletion, subdeletion, ellipsis and coordinate reduction in the English comparative sentences. Furthermore, their interrelated different aspects can be discussed and analyzed by the structural properties of the syntactic frameworks occurring in the comparative construction. < Kyungnam University >
