CT findings of twenty-four patients with adrenal gland tumors were analyzed to evaluate their location, size,shape, density etc. The post-surgical confirmation was made in 17 cases. The findings were as follows: 1. 4-10cmsized tumor messes were most common (42%). 2. Round or oval shaped forme were most common (59%). 3. Functionaltomors were 71% (17/24) including Cushing's syndrome of 10 cases, pheochromocytomas of 6 cases and aldosteronismof 1 case. 4. Abnormal adrenal glands were delineated in 88%(21/24), most effectively by CT. We concluded that CTwas the valuable study in the evaluation of the adrenal gland tumors and in the determination of surgicaloperation.

The authors present the one case of a 22-year-old man admitted with intermittent quadriparesis and respiratory difficulty. On investigation, atlantoaxial instability and upper cervical cord compression due to abnormal soft tissue were revealed. We have performed transoral decompression and biopsy, and then posterior transarticular facet screw fixation with interspinous wiring and fusion. We could obtain immediate and long-term postoperative stability with Philadelphia collar only. The pathologic examination reveald connective soft tissue hypertrophy due to chronic mechanical irritation.

PURPOSE: To demonstrate the characterization calretinin-immunoreactive displaced amacrine cells in the ganglion cell layer using immunohistochemistry and electron microscopy. METHODS: For immunohistochemistry, sections from guinea pig retina were incubated with mouse monoclonal antibody directed against calretinin. For double label studies, sections were incuated in mixture of mouse monoclonal anti-calretinin or rabbit polyclonal anti-calretinin with following antibodies: goat polyclonal anti-ChAT, rabbit polyclonal anti-GABA, mouse monoclonal anti-GABAA receptor alpha1, beta2/3. Sections were analyzed using Bio-rad Radiance Plus confocal scanning microscope. Stained sections from three guinea pig were observed with transmission electron microscope. RESULTS: Calretinin immunoreactivity was present in displaced amacrine cells and ganglion cells gaving rise to processes ramified in the inner part of the inner plexiform layer in stratum 4. The same stratum was also occupied by the dendrites of ON-cholinergic amacrine cells. Double-labeling demonstrated that dendrites and cell bodies of displaced amacrine cells colocalized with ON-cholinergic amacrine cells and dendrites of ganglion cells directly overlapped with dendrites of ON-cholinergic amacrine cells. The synaptic connectivity was identified by electron microscopy. Ganglion cell dendrites received synaptic input from ON-cholinergic amacrine cell. GABAA receptor beta2/3 subunit bands cofaciculates the dendrites of displaced amacrine cell and ganglion cell that are juxtapose to the alpha1 subunit of GABAA receptor. CONCLUSIONS: These results indicate that ON-cholinergic amacrine cells modulate calretinin-labeled ganglion cell via GABAA receptor beta2/3 in the guinea pig retina.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.
