Encephalocele and nasal glioma are rare, benign congenital neuroectodennal tumors which result from a failure of embryologic sepearation of neuroectodermal and ectodemlal tissues. Nasal glioma should be differentiated from a true glioma, and from a primary encephalocele, which is a herniation of the cranial contents through a bony defect in the skull. For this reason, nasal cerebral heterotopia is a preferred term. We report an unusual case of a nasal mass that was histologically indistinguishable from nasal cerebral heterotopia but proved to be connected to the skull base by fibrotic cord. The patient was a 2 year old girl who had had a slow growing palpable mass in the left epicanthal area for three months.

To evaluate the structural characteristics that might be related to the clinical features noted in preeclamptic patients with focal segmental glomerulosclerosis(FSGS), we analyzed post-partum renal biopsies of 8 preeclamptic patients with FSGS (group 1) by morphometry and glomerular studied the structural-functional relationships. These findings were also compared with those from three postpartum cases with minimal change lesion(group 2) and normal age-matched women(group 3). Mean glomerular volume (MGV) in group 1 and group 2 was (2.64 +/- 0.49) x 10(6) micrometer3 and (2.56+/-0.25)x 10(6) micrometer3, respectively. MGV in both groups was significantly increased compared with that of the control group [(1.11+/-0.22)x10(6) micrometer3](p<0.0005). The volume density of the mesangium/glomerulus [Vv(mes/glom)] in the group 1 patients was significantly increased (p<0.0001) when compared with that of the group 2 and the control group patients. The increment of Vv(mes/glom) was related to both the mesangial cell proliferation and expansion of mesangial matrix. The volume density of the capillary lumen/glomerulus [Vv(cap/glom)] in group I was significantly decreased(p<0.0001) when compared with that of group 2 and the control group. Vv(cap/glom) was directly related to Ccr in group l(r=0.70, p=0.05). These results suggest that reduced capillary luminal area caused by mesangial interposition is related to the decreased glomerular filtration rate in preeclamptic FSGS.

Somatostatin secreting islet cell adenoma(somatostatinoma) of the pancreas is a rare entity. Less than 30 cases of pancreatic somatostatinoma could be searched in the world literature. We present a case of somatostatinoma of the pancreas in a 64-year-old woman. This patient had suffered from diabetes, cholelithiasis and intermittent diarrhea. Laboratory examination revealed steatorrhea, blood somatostatin level of 30 pg/ml, and fasting blood glucose level of 116 mg/dl. Subtotal pancreatectomy was done after radiological demonstrations of a round tumor mass in the pancreas. It was a 2 cm-sized well demarcated yellowish brown round solid mass located in the proximal pancreas. A retention cyst was seen just distal to the tumor. Histologically, tumor masses consisted of polygonal cells with distinct cell border, having granular eosinophilic cytoplasm and small bland looking nuclei. The tumor cells were arranged in small solid islands and trabeculae, separated by fibrovascular stroma. Immunohistochemical stain for somatostatin was positive in the cytoplasm of the individual tumor cell, and ultrastructurally variable sized membrane bound electron dense granules of 200 nm in average diameter were found in tumor cells.

Hamartoma of the bladder is quite a rare entity which is composed of a disorderly admixture of mature cellular elements normally present in the urinary bladder. There is a great controversy regarding the pathogenesis of this lesion. Whether it is a true hamartomatous lesion or metaplastic lesion developed secondary to the inflammatory process. Similar or identical lesions has often been given by other names such as florid examples of cystitis glandularis. We prefer to cell florid examples of cystitis glandularis rather than hamartoma when it was occurred in an old age higher then 50th decade. Here we report a case of hamartoma of the urinary bladder in 44 years old man. Cystoscopic examination revealed a papillary polypoid mass which was attached to the fundus of bladder by long stalk. The mass measured 1.5 cm in greatest diameter. It was composed of epithelial nests resembling von Brunn's nest, cystitis glandularis or cystitis cystica dispersed in a stroma rich in smooth muscle and fibrous tissue.

PURPOSE: Telomerase is known to play a role of adding repetitive parts to chromosomal ending and to be involved in carcinogenic process through cell immortalization. The purpose of this study is to evaluate that restraining of telomerase activation can have killing effect on cancer cell and enhance susceptibility of cancer cells to anticancer substance. METHODS: The killing effect on melanoma cells was studied by using recombinant adenovirus that makes it possible to inhibit telomerase from getting activated, with such targets as two types of melanoma cell lines. This recombinant adenovirus was used combined with cisplatin, one of the most representative anticancer medicine to evaluate enhancement in susceptibility of cancer cells to anticancer substance. RESULTS: From the result of cytotoxic assay, it is found that melanoma cells have much resistance to cisplatin on the whole. In the case of using Ad-OA of recombinant virus alone, killing effect on melanoma cells was insignificant. On the other hand, when Ad-OA was used in combination with cisplatin, susceptibility of melanoma cell lines to cisplatin was enhanced. CONCLUSIONS: Ad-OA, recombinant adenovirus, could be used as a supplementary medicine in the targeted cancer gene therapy against cancer cell lines resistant to cisplatin.

Atherosclerotic heart disease is a major source of cardiovascular morbidity and mortality in adult populations. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 50 subjects with atherosclerotic heart disease by echocardiography and compared with 27 control subjects. We found significant change(p<0.05) of aortic root dimension, left ventricular mass, mitral valve E-F slope, E-point septal separation, and functional measurements show significant change in ejection fraction and fractional shortening of left ventricle. Characteristically, abnormal septal movement reveals in 70% of patients including paradoxical, flat & diminished, hyperactive motion, and among them paradoxical movement is the most frequent. Also left ventricular posterior wall movement is abnormal in 30% of the patient group. The prevalence of echocardiographic abnormalities is 80 percentile of total, which include 30 percentile subjects with only echocardiographic abnormalities without abnormality in 12-lead ECG, chest X-ray and laboratory findings. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.

There had been a continuous evolution of lymphoma classification and recently a Revised European-American Lymphoma Classification was proposed by the International Lymphoma Study Group. This new classification often requires information on immunophenotypic and molecular biologic markers in addition to the usual histologic findings. Recent advances in the production of commercially available monoclonal antibodies reactive on formalin-fixed paraffin-embedded tissues provide us a great help to classify the non-Hodgkin's lymphoma. We have analyzed 31 low grade B-cell lymphomas by the schemes proposed by the International Lymphoma Study Group using antibodies to CD3, CD5, CD20, CD23, CD43, cyclin D1, and bcl-2 protein, and have analyzed the immunophenotypic features. Among 31 low grade B-cell lymphomas, 8 small lymphocytic lymphomas, 5 mantle cell lymphomas, 7 follicle center lymphomas (2 grade I, 3 grade II, and 2 grade III), and 11 marginal zone B-cell lymphomas (all of which were extranodal) were identified. Among 8 small lymphocytic lymphomas, 5 cases were positive for CD5; 6 cases were positive for CD23; 7 cases were positive for CD43; all 8 cases were negative for cyclin D1; and 7 cases were positive for bcl-2. Among 5 mantle cell lymphomas, 4 cases were positive for CD5 and CD43; all five cases were negative for CD23; 4 cases were positive for cyclin D1 and bcl-2. All 7 follicle center lymphomas were negative for CD5, CD43 and cyclin D1 and 2 cases were positive for CD23; and 6 cases were positive for bcl-2. All marginal zone B-cell lymphomas were negative for CD5, CD23 and cyclin D1; 3 cases were positive for CD43 and 9 cases were positive for bcl-2. Diagnostic utility for CD5 antigen detection on paraffin embedded tissue has a limitation due to weak antigen expression in tumor cells of B-cell lymphomas; however, still be useful in differentiating small lymphocytic lymphoma and mantle cell lymphoma from other B-cell lymphomas when applied in conjunction with CD43. CD23, CD43, and cyclin D1 appear to be of great help in differentiating subgroups of low grade B-cell lymphomas. Bcl-2, as known, is found to be useful to rule out reactive follicular hyperplasia.

BACKGROUND: Cardiac hypertrophy is the compensatory response of the myocadium to increased workload. Compensatory mechanisms come into play when the hypertrophied heart can no longer accommodate the increased demand or persistent stimuli. Although it has been reported that the molecular changes in hypertrophied hearts that initially mediate enhanced function may contribute to the development of heart failure, the structural/biochemical/molecular basis for myocardial contractile failure is still obscure. This study was aimed to clarify the structural basis for relation between hypertrophy and failure. METHOD: Nine pairs of rabbits were sacrificed at 8,12,24,48 hours and 1,2,4,6,8 weeks after experiment aortic constriction. There hearts were studied with routine histopathology. Each heart was weighed and compared with total body weight. Multiple sections were embedded in paraffin, sectioned at 5um, and stained with hematoxylin and cosin and Masson's trichrome and analysed. RESULTS: The heart weight to body weight ratio(g/Kg) increased progressively with time after aortic banding. Banding of the aorta in the rabbit resulted in multifocal areas of myofiber degeneration, necrosis and fibrosis through the wall of the left ventricle, in the papillary muscles of the left ventricle and in the left ventricular portions of the interventricular septum in rabbit of 6 and 8 weeks after aortic banding. By 4 weeks after banding, the foci of necrosis were not observed. CONCLUSION: There findings suggest that the increased necrosis, fibrosis in animals with cardiac hypertrophy induced by banding the aorta may play a role in progression to heart failure.

Extramammary Paget's disease is a dermatosis which pathologically and clinically resembles Paget's disease of the breast. The disease occurs in regions with apocrine gIands; most often in the anogenital area, seldom in the axilla. umbilicus, mucous membrane of the mouth, nose, ear and Moll's gland of tne eyelid. In this work the effect of bleomycin for extramammary Paget's disease was studied on ultrastructural aspect. The material was a case of extramammary Paget's disease of 7 years standing occuring in the scrotum and the pubic area by serial sections after IV injection of 60mg, 120mg and 240mg of bleomycin, and examined under the electron microscope. The results obtained are summarized as follows: 1. The size of Paget's cell and its nucleus was gradually decreased. 2. The numbers of lysosome, dense body, autophagic vacuolization and tonofilament was decreased. From these fidings, it is suggested that bleomycin induces retrograde degenerative change of Pagct's cell, and cell necrosis finally.
