Fine needle aspiration(FNA) has been quite successful in identifying benign and malignant breast lesions, but a "gray zone" exists. A total of 697 FNAs of breast were performed at Korea Cancer Center Hospital for a period of one year. One hundred and eleven of the 697 FNAs were diagnosed as atypical or suspicious for malignancy. Among them, we reviewed 74 FNAs, un which histologic diagnoses were made, and applied cytologic grading system proposed by Masood et al (1990) to evaluate the usefulness of this system in minimizing the size of gray zone. Technical problem was responsible for equivocal diagnoses in 19 FNAs Of the remaining 55 FNAs, 18 were benign and 37 were malignant. Among benign conditions, fibroadenoma(5 cases) and fibrocystic disease with fibroadenomatous feature(3 cases) constituted the largest groups. The majority of malignant conditions were infiltrating ductal carcinoma(29 cases), however, those low grade carcinomas Including tubular carcinoma(3 oases), cribriform carcinoma(2 cases), and mucinous carcinoma(2 cases) occupied a relatively large proportion Cytologic grading system was quite useful in minimizing the size of gray lone. The scores of 27 out of 29 usual infiltrating ductal carcinomas belonged to the group of cytologic malignancy, how-ever, only 2 out of 7 low grade carcinomas got scores of malignancy FNA from fibroadenoma or fibrocystic disease with fibroadenomatous features showed a tendency toward high scores. Experience of the cytopathologist and familiarity with cytologic alteration in breast disease cannot be overemphasized.

Purpose : Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. Methods : Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. Results : In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. Conclusion : Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.

Thymoma is the most common anterior mediastinal tumor in adults. Rarely, it is presented as the anterior neck mass, commonly located in the anterolateral aspect of the neck or adjacent to the thyroid. We experienced two cases of fine needle aspiration cytology of thymoma, mimicking thyroid mass. The first case was an ectopoic cervical thymoma in a 31-year-old female. The fine needle aspiration cytology was misinterpreted as reactive hyperplasia of lymph node. But the histologic diagnosis was thymoma, predominantly lymphocytic type. The second case was an invasive thymoma in a 66-year-old female, who complained a large anterior neck mass. The fine needle aspiration cytology revealed biphasic population of some clusters of epithelial cells and scattered lymphocytes. The cytologic diagnosis was thymoma and was confirmed as invasive thymoma after the biopsy. Therefore, when the cytologic feature of anterior neck mass shows the both lymphocyte and epithelial component, the differential diagnosis should Include the possibility of thymoma.

Acute abdominal Aortic occlusion is rare but it is a vascular emergency with high mortality and morbidity. There­fore, delay in diagnosis can have severe impact on the prognosis. A 60-year-old women complained of paresthesia, paralysis, and severe pain in bilateral lower extremities on 13th day after open heart surgery for mitral stenosis, atrial fibrillation, coronary arterial stenosis, tricuspid regurgitation, and atrial septal defect. Her skin was mottled and cool from the umbilicus to the feet, and there were no palpable pulses in the lower exteremities. We diagnosed an acute abdominal aortic occlusion using the Multi-Detector Row Spiral Computed Tomography and successfully treated the problem with emergent thrombo-embolectomy and Aortobifemoral bypass.

Receptor-mediated endocytosis of coelomic fluid proteins (CP), yolk precursor proteins, appears to be regulated by multiple GTP-binding proteins during oogenesis of a polychaete, Pseudopotamilla occelata. Transport of 125 I-CP into the oocytes of intermediate size class, at which CP is the most actively transported, is enhanced by GTP but inhibited by GTP analogues, either GTPrS or GTP$\beta$S. The effects of GTP and GTPrS on the transport were also confirmed by tracing internalization of gold-labeled CP with transmission electron microscope. Internalization of gold-labeled CP into the yolk granules was enhanced by GTP but inhibited by GTPrS.

We experienced six cases of pseudoaneurysm of the peripheral artery which occurred after stab wound or after diagnostic and operative procedures. Among 6 cases, 4 cases of pseudoaneurysm were developed in the femoral arteries, and others were the subclavian and the axillary artery. Two of 6 cases were combined with previous arterio enous fistula. Doppler imaging and angiogram were performed for the dignosis and an operation. Operative procedures were resection of the aneurysm, ligation of the involved arteries and reconstruction of the artery with the autogenous saphenous vein or the cephalic vein graft. Each operations were successfully performed without any disability.

The philosophers think that the increase of loneliness in technological society is caused by the reduced feeling to some extent. They started to think the integral feeling in terms of existentialism away from Visualcentrism. It is apparent that in architectural design a concrete feeling(sense) out of Visualcentrism of modern architecture is reflected in a architecture. In particular, the architects such as Herzog & de Meuron, Steven Holl, Peter Zumthor, Kuma Kengo think that the existential value of the objects is important and would like to reflect the existence of materials on architecture. This study is to analyze the common points and different points regarding how in these works sensible experiences are approached. The results show that these works have common features containing escape from visual formativeness in the space, pursuit of locational connection, study on pure essence of the materials, and reflectance of the feeling of depth and motility. In addition, the actual beings of the materials for this feeling were mainly used and showed some difference in terms of the usage of local materials, natural environment, five senses of body. This study is important in the point of view that there are few researches that compared with the characteristics of architects' works while there were many researched that treated architecture as sensible view.

A 30 year-old female patient was admitted for dizziness and palpitation. Pulsation of the both upper extremities and both common carotid arteries were absent. Innominate artery and both common carotid arteries were severely narrowed and both subclavian arteries were completely obstructed on aortogram. The patient was diagnosed as tvue Ⅰ Takayasu's arteritis, and operation was peformed to increase blood flow to the brain and both upper extremities. Ascending aorta, both carotid arteries, both subclavian arteries, and both axillary arteries were exposed by four separate incision, and we performed an aorto-bicarotid-biaxillary bypass with Hemashield graft. Previous dizziness and palpation were disappeared after the operation.
