Loss of radial nerve function in the hand results in a significant disability and so cannot extend the wrist, thumb & fingers according to the injury levels. Therefore the patient has great difficulty in grasping objects, especially power grip. Tendon transfers to restore function of extension of wrist and fingers are among the the best − most predictable transfers in the upper extremity. We performed 13 cases of tendon transfers for radial nerve palsy and extensive extensor ruptures from 1987 to 1993. The results were evaluated according to Arbitrary Value Method. Among 13 cases 30% of excellent, 46% of good, 24% of fair and no poor result were obtained and the better results were obtatined in low radial nerve lesion.

The parathyroid cyst is a relatively uncommon disease and usually identified during the operation for a presumed thyroid mass. Thirteen cases of parathyroid cyst (2 males, 11 females) treated from 1981 to 1993 were reviewed. Ages ranged from 17 to 59 years(mean, 41 years). Gross measurement of the tumor size varied from 1.0 to 10.0 cm in diameter with a mean of 4.8cm. All of the 13 patients presented with a chief complaint of painless anterior cervical mass. Only one complained of mild symptom of dyspnea and voice change due to huge cyst in paratracheal space. No functional cyst was identified. Diagnostic studies included ^99mTc thyroid scan (n=11), ultrasonography (n=10), computerized tomography (n=4) and fine needle aspiration(FNA) (preoperative, n=4; intraoperative, n=3). All diagnostic precedures but needle aspiration were nonspecific. Cysts were found in right inferior parathyroid(n=4), left inferior parathyroid (n=7), or anterior superior mediastinum (n=2). The FNA of the cyst contents revealed watery clear fluid with elevated parathyroid hormone level and was diagnostic in each cases. Four patients were treated initially with needle aspiration, of which only one patient was successful, and 3 patients who were unsuccessful to needle aspiration and the remaining 9 were effectively treated with surgical extirpation. Our experience suggested that needle aspiration may be of significant help in diagnosis and treatment of parathyroid cyst, but most of the patient could be treated successfully by surgical extirpation with an excellent chance for curability.

3.The Effect of Moderate Hypothermia on Infarct Size and Early Change of Regional Cerebral Glucose Uptake in Permanent Focal Cerebral Ischemia in the Rat.
Journal of Korean Neurosurgical Society 1997;26(6):772-779
Using a rat model, this study examined the cerebral protective effect of moderate hypothermia and evaluated the effect on early local metabolic change of permanent focal cerebral ischemia. The middle cerebral artery(MCA) of the rat was approached subtemporally and was occluded, and its surface was cooled. Cerebral infarct size was measured at 1, 4 and 7 days after MCA occlusion in non-treated(n=27), 2-hour hypothermia(n=27) and 3-hour hypothermia(n=27) group, respectively, and regional cerebral glucose uptake(rCGU) was determined at 1 and 4 hour after MCA occlusion in the non-treated(n=8) and 3-hour hypothermia(n=8) group, respectively. Infarct size measured at 1, 4 and 7 days after MCA occlusion was 22.2%+/-4.4%, 14.3%+/-6.6%, 13.7%+/-5.3% in the non-treated group, 19.6%+/-10.0%, 12.5%+/-6.2%, 12.0%+/-6.9% in the 2-hour hypothermia group and 12.9%+/-5.6%, 8.3%+/-3.3%, 8.2%+/-2.3% in the 3-hour hypothermia group. In the 2-hour hypothermia group, no significant size reduction was seen, but in the 3-hour hypothermia group, infarct size had decreased to half of that of the non-treated group(p<0.05). This protective effect was observed untill 1 week after MCA occlusion. rCGU in the non-treated group measured at 1 hour after MCA occlusion had increased in the periphery of the ischemic core, but at 4 hours, periischemic hypermetabolism had disappeared and the area of low metabolism in the center had become larger. rCGU in the 3-hour hypothermia group measured at 1 hour after MCA occlusion(BT 26degreesC) showed a uniform decrease in all regions, supressing temporary periischemic hypermetabolism, and at 4 hours(BT 37degreesC) after occlusion, hypermetabolism was not prominent and the area of low metabolism in the center had narrowed. This study indicates that 3 hour moderate hypothermia immediately after MCA occlusion significantly reduces infarct size, and that this protective effect was associated with suppression of periischemic hypermetabolism occurring around 1 hour after MCA occlusion.

4.The Feasibility of Histopathological Diagnosis on the Basis of CT Findings in 60 Consecutive Supratentorial Gliomas.
Journal of Korean Neurosurgical Society 1980;9(1):25-38
For assessment of the feasibility of histopathological diagnosis on the basis of CT findings in suratentorial gliomas, 60 consecutive histologically proven cases were analysed. Benign astrocytomas(Kernohan's grade I, I-II, II) were 25, Oligodendrogliomas 6, malignant gliomas(Kernohan's grade III, III-IV, GM) 29 in number. Plain CT findings and degree of peritumoral edema were less significant than the patterns of contrast enhancement in predicting the histological malignancy. Calcification, if present, excluded the diagnosis of malignant gliomas. Combining the CT criteria of pattern of contrast enhancement, degree of peritumoral edema with angiographic signs of malignancy in addition to the clinical feature, a more confident histological diagnosis seemed allowable.

5.The Use of Nd-YAG Laser in Neurosurgery.
Journal of Korean Neurosurgical Society 1984;13(1):127-130
The authors report our experiences with the use of Nd-YAG laser in extripation of selected intracranial tumors:5 Meningiomas, 1 Acoustic neurinoma, 1 Hemangioendothelioma and 1 Oligodendroglioma. The Nd-YAG laser is very helpful to coagulate the pathologic vessels. And because of it's excellent coagulation the Nd-YAG laser is particularly useful when applied in highly vascular tumor as well as in high contents of mesenchymal structures within the tumors.

The purpose of this study was to examine the frequency of eutaneous disorders in patients with chronie renal failure presently on hemodialysis(HD). The results were as follows. 1. Cutaneous lesions were present in all 78(100% ) patients with chronic renal failure. 2. The frequency of msjor cutaneous problems associated with chronic renal failure was as follows: xerosis(82.1%), pruritus(74.4%), nail changes(74.4%), hyperpigmentation(70.5 % ), xerostomia(42.3'Yo), poor wound healing(37.2%), easy bruisability(30,8%), hypotrichosis(21.896), and purpura(14.1 % ). 3. Cutaneous problems which appeared after the initiation of HD were. appearance of new pigmented nevi or lentigines(9 patients), appearance or aggravation of acne(6), contact dermatitis at AV fistula site(2), gynecomastia(1), extensive flat warts(1), extensive tinea versicolor(1), and extensive vitiligo(1). 4. Among 55 patients with hyperpigmentation, 11 patients reported decreased pigmentation following HD. In 15 patients, hyperpigmentation worsened following HD, and in 9 patients hyperpigmentation first appeared after HD was initiated. 5. Cutaneous disorders favorably affected by HD were as follows: easy bruisability(3/ 24), xerostomia(3/33), gingival friability(2/7), and hypotrichosis(5/17). 6. Poor wound healing and xerosis were not improved by HD. 7. Among 58 pruritic patients, 7 patients were improved after HD, 7 patients became worse during each HD, and 3 patients were not pruritic only for 2 to 3 days after each HD. Four patients experinced pruritus only during each HD. 8. There was no significant statistical difference between the frequency of pruritus and xerosis and the levels of blood urea nitrogen, calcium, phosphorus, and parathyroid hormone.

Journal of Korean Neurosurgical Society 1985;14(1):131-138
The authors reviewed forty cases of acoustic neurinomas operated on from July 1974 to June 1984, analyzing our data obtained during 10 years in the following three periods: 1974 to 1978, 1978 to 1981, 1981 to 1984. A suboccipital approach was used for the removal of acoustic neurinomas in all cases. 1) A peak in the age distribution was seen at 40-50 years of age and no sexual difference was present. 2) The earliest symptoms were hearing loss(50%), headaches(25%), tinnitus(15%) in order of frequency. The time between onset of complaints and admission was mostly within 5 years(83%). 3) Most of the patients had large tumors(78%), greater than 3cm, of whom 4 patients were free of cerebellar and brain stem dysfunction. 4) Total removal was carried out in 27 out of 40 patients(67%) and particularly in 8 out of 14 patients(57%) with large tumors greater than 5cm. The total mortality was 7.5%. 5) In the last 3 years with the advance of microsurgical technique and CT scan, 25 patients were operated on only with a single death and total removal was carried out in 20 out of 25 patients. 6) In total removal, the total mortality was 7.4% and the mortality was 8% in patients with 3-5cm sized tumors and 13% in patients with tumors greater than 5cm, particularly 5% in the recent 3 years. 7) Preservation of the facial nerve following total removal was achieved in 59%. In the recent 3 years, the facial nerve was preserved in 65%. In the large tumors, 3-5cm sized and greater than 5cm, the rates of 75% and 37% were obtained.

Korean Journal of Urology 1997;38(9):951-956
Heat Shock Protein (HSP) is a genetic product reacting on stress. HSP is increased by physiological or environmental stress and expressed at gastrointestinal tumors such as stomach cancer, pancreatic cancer and large intestinal cancer, and at other various tumors such as lymphoma and breast cancer. The role of HSP is to interrupt the process of apoptosis interfering with formation of tumors, and weaken function of tumor control beyond that of immune surveillance. In case of causing the normal p53 to be mutated, it leads to morphological change of p53 protein and combine with HSP. But, it has not been clarified yet. We intend to examine the meaning of HSP 70 in bladder tumor by investigating the relations among HSP expression and tumor stage, tumor grade, P-gp (glycoprotein) expression as a product of multi-drug resistant gene, and p53 expression in 59 cases of bladder tumor. 1) There were HSP expressions of 8 cases (22%) among 36 superficial bladder tumors and of 9 cases (39%) among 23 invasive bladder tumors. 2) HSP positive reactions were observed in 1 case (8%) of 13 Grade I, and 6 cases (29%) of 21 Grade II and 10 cases (40%) of 25 Grade III. 3) Positive reactions of HSP were showed in 10 cases (40%) among 25 P-gp expression, and in 7 cases (21%) among 34 P-gp non-expression. 4) The p53 proteins were expressed in 12 cases (29%) among 42 ones of HSP non-expression and in 8 cases (47%) among 17 ones of HSP expression. 5) Positive reactions of HSP were showed in 9 cases (23%) among 39 ones of p53 non-expression, and in 8 cases (40%) among 20 ones of p53 expression. 6) 5 patients of 6 with negative expression of HSP and strong positive expression of p53 had poorly differentiated transitional cells, in which one of the patients accompanied with lung metastasis. In view of above study, HSP expression has no correlation with P-gp and stage in bladder tumor, but it has probable pertaining to tumor grade and p53. As it were, tumor cellular differentiation and p53 expression have weak correlations with HSP 70 expression. Meanwhile, judging from poor differentiation, in most cases of HSP non-expressed but p53 strongly expressed, HSP is insufficient to be a prognostic factor of bladder tumor independently, however, in case of using it, as supplementary one, concurrently with p53, it would be valuable prognostic factor in bladder tumor.

10.Microvascular Anastomosis.
Journal of Korean Neurosurgical Society 1977;6(2):465-468
By using technique of microvascular anastomosis under the operating microscope experimental aneurysms were produced in seven rats. These experimental aneurysms were adequately excluded by progressive carbonization of aneurysmal sac and then the remained portion of aneurysmal sacs were reinforced by wrapping with ethyl 2-cyanoacrylate. In this acute experiment all of the common carotid arteries were satisfactorily patent.
