Castleman's disease(Giant lymph node hyperplasia) is a pathologic entity of unknown etilogy, as attested to bythe number of names it has received, lymphoid hamartoma, angiomatous hamartoma, and giant lymph node, etc.Although the mediastinum is its most common location, it also occures in other areas of the body, usually wherelymph nodes are normally found. Authors have been experienced 2 cases of histologically porven Castleman's diseaseduring recent 3 years in Kyung Hee University Hospital, and present its radiological and pathological findings asmediastinal mass.

BACKGROUNDS: The inflammatory reaction after cerebral ischemia involving adhesion molecules aggravates neurologic deficit. This study aimed to study the change of plasma level of the adhesion molecules after acute cerebral ischemia. METHODS: Nineteen patients with acute cerebral infarction and ten control subjects without a history of cerebrovascular disease were included in this study. The patient groups were subgrouped into large artery atherosclerosis and small artery occlusion groups according to TOAST classification. Plasma levels of sP-selectin, sE-selectin, sICAM-1 and sVCAM-1 were measured within 24 hours and in 6 to 8 days after acute ischemic infarction. RESULTS: The plasma level of sP-selectin was elevated in acute stroke patients within 24 hours and in 6 to 8 days after stroke onset compared with control group(p<0.05). But plasma levels of sE-selectin, sICAM-1 and sVCAM-1 were not different from those of control group. The plasma level of sP-selectin was significantly elevated in large artery artherosclerosis group compared with control group. CONCLUSION: This study suggest that P-selectin actively involves in inflammatory process after acute ischemic stroke, especially associated with atherosclerosis.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

To evaluate the typical appearance and the influence in the image interpretation of the metallic artifact which is known as one of the patient-related field artifacts, we analysed the magnetic resonance (MR) images of 40 patients (the total number of metallic materials were 45) acquired at MR 1.5T unit. All patients were screened for the presence of metal. The metallic implants were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts produced by metallic objects can be seen on MRI as the focal loss of signal and/or the local distortion of the image. Regardless of their ferromagnetic properties, metallic implants created regional artifacts in their images. Ferromagnetic materials, such as a lead fragment, showed severe artifacts and nonferromagnetic metals showed mild to moderate artifacts. The conspicuity of artifact was related tot he composition, mass, shape, orientation, and the location of the metallic objects in the body. Under high magnetic field strength, there were no significant differences between the various pulse sequences. Artifacts are particularly prominent on gradient-echo images. Our findings indicate that MR imaging of patients with standard nonferromagnetic metallic materials can be successfully performed and usefully interpretated.

BACKGROUND: The purpose of this study was to evaluate the applicability of the Korean version of Fall Efficacy scale(FES) and Activities-specific Balance Confidence Scale(ABC) to Korean older adult through an examination of instrument`s internal consistency and validity METHOD: A sample of 90 Korean older adults who lived in a community completed a survey instrument which included Korean version of FES and ABC. Because of comparable data derived from each scale, fear of falling and quality of life, activity daily living were included. Concurrent validity, criterion validity and correlational validity were tested. Reliability was tested by internal consistency, test-retest method. RESULTS: Cronbach`s alpha was 0.9043 in FES, and 0.99623 in ABC. Test-retest correlations in all scales were higher than 7.0. Statistically significant association was found between fear of falling and both scales. Correlation coefficient between Quality of life(SF-8) and ABC was -0.142(p=0.049). Both FES and ABC are correlated significantly each other. CONCLUSION: The Korean version of FES and ABC appears to be a reliable and valid method for meas- uring fear of falling. These instruments may be useful in assessing the independent contribution of fear of falling. ABC scale may be more useful to detect loss of balance confidence in more highly functioning seniors.

Lichen amyloidosis is a chronic, benign and relatively rare disease, but not infrequent in Korea. The patients with lichen amyloidosis visited to Dermatologic Department of Severance Hospital in 1969. The results of clinico-pathological findings observed in above patients were presented. Case 1-A 56 year old farmer has been suffered from pruritic lichenoid papules which developed in the right pretibial area for 10 years. These papules were reddish-brown in color, 1 to 2mm in. diameter and closely aggregated. The whole gross lesion measured 10 by 25 cm. Cases 2-A 32 year old obese house-wife complained of pruritic eruptions in the right pretibial area for 3 years. Shiny firm papules, measuring approximately 2 mm in diameter, were red in color and gross entire lesion was estimated to 7 by 10 cm. Histological examination by employing the stain method of crystal violet and the Nomland test demonstrated the amyloid mass in the papillary portion of dermis. All laboratory studies including complete blood count (CBC), chest X-ray, sedimentation rate, urinalysis (including test for Bence Jones protein), blood glucose, blood urea nitrogen (BUN), serum cholesterol, venereal disease research laboratories test for syphilis (VDRL), stool for occult blood, serum protein electrophoresis, electrocardiogram (ECG) and intravenous congo red test, were within normal limit. The therapeutic results were not promissing, however itching and lichenoid papules were disappeared during the treatment with steroid cream for occlussive dressing therapy.
