Many pictures must be taken for the presumption of the stereorelation of the cerebral artery, which obtained with ordinary cerebral angiography. And it is very difficult to understand the stereoimage and required many experiences. But it is able to presume the stereorelationship in only brief eye's training without the aid of the stereoscope using the prism. For the stereoview, we need the paired angiograms obtained only straight and tilting the X-ray tube. In practice, with this stereoview in cerebral angiogram, we could know the directions of the aneurysmal neck and fundus with the stereorelationship of the cerebral artery and indeed helps us greatly in operation field. In addition, we might guess the location and stereorelationships of the feeding artery and draining vein in arteriovenous malformation and other vascular tumors and it was great aid in diagnosis and operation. Now we present the methods of the pictures for the stereoview in cerebral angiogram and the methods for eye's training.

Although there are various methods of operative treatment for hony mallet finger, the operative technique is not so easy and complications such as joint stiffness, sott tissue prohlems, infection, change of nail shape and arthrosis are common. The authors performed operations for 26 cases of hony mallet fingers, fixing the hony frapment by Kirschner wire, pull-out wire suture and miniscrew respectively, from Jan. l988 to Jun. l996. The results were as follows. l. According to Niechajev's classification. there were 3 cases of type B, 7 cases of type C, l4 cases of type D, and 2 cases of type E. And 11 cases were accompanied hy crushing injury. 2. Involved fingers were third finger in 11cases, fit'th finger in 7 cases, fourth finger in 5 cases, second finger in 2 cases. and thumb in I case. 3. The hony mallet finger was caused hy occupational injury in l6 cases, direct blow in 7 cases and sports injury in 3 cases. 4. The fractured fragment was fixed hy Kirschner wire in 9 cases, by pull-out suture in 9 cases and by miniscrew in 8 cases. 5. The results were evaluated hy Kanies scale. Sixteen cases had satisfactory results. Seven cases (87.5%) were satisfactory in miniscrew fixations. 5 cascs (55.6%) in pull-out wire suture methocls and 2 cases (22.2%) in Kirschner wire tixations. 6. The complications were joint incongruity in 4 cases, dorsal prominece in 6 cases, painful limitation of motion in 2 cases which were treated by arthrodesis, pin site infection in 2 cases and hreakage of wire suture in 1 case. 7. The miniscrew fixation offered relatively firm fixation, low complication rate, and good results. so it can be considered as one of the good methods of treatment for hony mallet finger.

Fine needle aspiration cytologic findings of four cases of chondrosarcoma were described. The cases consisted of one primary scapular tumor, two recurrent shoulder masses, and right upper quadrant mass which developed after an A-K amputation for an unknown tumor. The aspirates characteristically revealed cell-rich smears containing clusters and isolated cells having abundant cyanophilic cytoplasm and round to oval or elongated vesicular nuclei. The cytoplasm was occasionally foamy. The nuclei were usually small but prominent. Nuclear atypism and pleomorphism were frequently associated. The last case showed epithelioid sheets of polygonal cells, possibly representing chondroblasts, and a well differentiated chondroid element. The fine needle aspiration could be a good diagnostic tool for primary, recurrent, and metastatic chondrosarcomas.

CTLA-4 (=CD152), a T cell activation antigen, has been known to be homologous to CD28 in its molecular and genomic structure. Both of these two molecules are sharing their counterreceptors, B7 (CDSO) and B7-2 (CD86) and are known to play a crucial role in T cell activation. In previous our study it was reported that there are 2 forms of CTLA-4 antigen in activated human T cells, 30 kD membrane-bound form and 34 kD cytosolic-sequestered form and the former was less than 5 % of total of this antigen induced. Aims of this study are to confirm previous finding by using flow cytometry and to characterize the cytoplasmic form of human CTLA-4 by using ultrafiltration and immunoprecipitation techniques. In PHA stimulated peripheral blood lymphocyte surface expression of CTLA-4 was less than 2.1% of any of CD4+, CD8+ and CD56+ subsets. And the 34 kD form of CTLA-4 was detected in CDS+ subset only. This discrepancy confirms that 34 kD antigen is the cytoplasmic form of human CTLA-4. In ultrafiltration and subsequent Western blot analysis study this 34 kD antigen was detected in >100 kD fraction only. And in non-reducing condition this antigen formed high molecular weght complex (MW > 350 kD). In immunoprecipitation study using anti-peptide A antibody it was found that this high molecular weight complex consists of the 34 kD cytoplasmic form of CTLA-4 and previously unknown 54 kD antigen and 46 kD antigen at 1:1:8-10 ratio. And none of these 3 molecules were identified in membrane fraction of activated human T cell. The result of this study implies that CTLA-4 molecule induced upon T cell activation mainly sequestered in cytoplasrn and another signal is necessary to target this antigen on the activated T cell surface.

Thermography is a sensitive and reliable method for diagnosis of radiculopathy. Skin temperature alterations of the involved dermatome named thermatone are diagnostic for sensory root involvement in radiculopathy which can be demonstrated by thermography. Digital infrared thermographic imaging system using computer is development and could measure thermal difference more exactly without hazards or discomforts to patient. Authors present 186 cases of thermographic evaluation in herniated lumbar disc disease by digital infrared thermographic imging system and the results are evaluated with literature review.

Overexpression of the nuclear phosphoprotein p53 is the most common genetic anomaly found in primary human cancer and mutation of the tumor suppressor gene p53 has been identified in breast cancer cell lines. In this study, we evaluated the prognostic significance of p53 protein expression in patients with mammary infiltrating ductal carcinoma and its correlation with histopathologic grade, lymph node status, tumor size, p53 protein expression and survival. Among 53 cases, p53 protein expression was detected in 26(49.1%) cases by immunohistochemistry. There was no correlation between p53 protein overexpression and histopathologic grade(p=0.09) or lymph node status(p=0.38) and between survival and histopathologic grade (p=0.68) or lymph node status(p=0.52). However, p53 protein expression was significantly correlated with survival(p=0.01) and patients with p53 protein-positive tumors showed poorer survival times. But Cox multivariate analysis showed the lymph node status is significant(p=0.01). The authors conclude that the presence of mutant p53 protein and lymph node status may serve a prognostic role, in a subset of mammary infiltrating ductal carcinoma cases.

A case of sacrococcygeal chordoma diagnosed by fine needle aspiration is presented. This is a case of a 54-year-old woman who came with coccygeal pain of 5-6 months duration. Aspiration biopsy cytology revealed many nests of cells having abundant bubbly cytoplasm and round to oval variably sized nuclei. The cells had indistinct cytoplasmic borders and many of the cells had cytoplasmic vacuoles. The nuclei had thin regular nuclear membranes, finely granular chromatin and one or two small nucleoli. The cells were generally monotonous, but focally pleomorphic with giant cell formation. Mitotic figures were scanty. The backgroud of the aspirate contained abundant mucinous materal. These findings were typical of those of recorded chordoma cases and the diagnosis was confirmed by a following open biopsy. The patient received 4,000 rads of neutron radiotherapy and has been well till March '88.

A 70-year-old woman with Parkinson disease was admitted to the emergency department with altered consciousness, fever and convulsive movements without experiencing withdrawal from antiparkinsonian medication. Six hours after the emergency department visit, the patient had a hyperpyrexia (>40℃) and a systolic blood pressure of 40 mmHg. There was no evidence of bacterial infection based on extensive workups. The patient was discharged without aggravation of Parkinson disease symptoms after treatment that included administration of dantrolene sodium, enforcement of continuous renal replacement therapy and cooling blankets. Malignant syndrome should be suspected if high fever occurs in Parkinson disease patients without evidence of a definitive infection.
