1.Inflammatory Gastric Adenocarcinoma with Neutrophil Leukcytosis.
Korean Journal of Pathology 1993;27(2):195-197
A 36-year-old man received a subtotal gastrectomy for Borrmann type 2 advanced carcinoma in the antrum of the posterior well. Preoperatively, peripheral white blood cell count was 16,400/mn3 with 80% of neutrophils. Microscopically, the tumor was of a poorly differentiated adeocarcinoma with intense eutrophilic infiltration which was totally confined within the neoplastic portion and in the metastatic focus in the regional lympho nodes. Repeated postoperative whits blood cell counts dropped down to the normal level. Neither infectious nor knowledge, this is the first case of gastric carcinoma with massive neutrophilic stromal reaction(inflammatory carcinoma) and leukocytosis in the literature in the korea.

In order to elucidate the possibility of diagnosis in soft tissue cysticercosis in case no parasite in it, immunohistochemical staining with antihuman IgG, IgM, and IgA and anticysticercus antibody in tissue section were carried out. Not only the differential counts of infiltrated plasma cells but also the parasite itself against to the anticysticercus antibody were observed. Materials stained immunohistochemically were consisted of 21 soft tissue cysticercosis with or without parasite. The results were as follows: 1) IgG producing plasma cells were most frequent (45.8+/-18.7) and followed by IgM (14.3+/-0.43) and (4.3+/-5.71). Number of IgG plasma cells were more frequently accompanied in the presence of cysticercus (55.9+/-17.7) than in the absence of parasite (39.7+/-17.1). 2) The mean+/-S.D. of plasma cells positive to the anticysticercus antibody were 28.2+/-18.7. And anticysticercus antibody producing plasma cells were more frequent in the presence of cysticercus (49.2+/-5.16) than in the absence of parasite (15.2+/-9.46). 3) Antigenicity of the cysticercus was strong in inner layer(#) followed by tegument(+) and fibrous layer(-). 4) Therefore, it could be suggested that antibody against to the cysticercus is mainly produced by IgG plasma cells and antigenicity of the worm is strong in the inner layer of cyst wall. In addition, there is a possibility of assisting the diagnosis of cysticercosis with anticysticercus antibody by immunohistochemically.

PURPOSE: Prostatic tumor induced gene-1 (PTI-1) is a mutated human EF-la and putative prostatic carcinoma tumor-inducing oncogene, that is differently expressed in prostatic cancer and benign prostatic hyperplasia. And, it is more sensitive marker than prostate- specific antigen (PSA) for detecting human prostate cancer in the bloodstream. This study invastigated the expression of PTI-1 in paraffin embedded tissue of prostatic carcinoma, prostatic intraepithelial neoplasia, and benign prostatic hyperplasia using in situ PCR. MATERIALS AND METHODS: we evaluated expression of PTI-1 in prostatic carcinoma with prostatic intraepithelial neoplasia (PIN) of 32 cases, benign hyperplasia of 20 cases, high grade transitional cell carcinoma of 10 cases and colon cancer of 10 cases for control group. Also, the immunohistochemical staining for PSA was performed to comparison with clinical value of PSA. RESULTS: The serum level of PSA was closely related to stage and Gleason score (p < 0.05). However, the results of immunohistochemical stains were variable to stage and Gleason score. PTI-1 using in situ PCR expressed in 50% of prostatic carcinoma, 41% of prostatic intraepithelial neoplasia, 10% of benign hyperplasia and colon cancer (p < 0.05). No expression is observed in transitional cell carcinoma. In prostatic carcinoma, PTI-1 expressed in 43.8% (7/16) of stage II, 50.0% (5/10) of stage III, and 66.7% (4/6) of stage IV (p<0.05). In PIN, expression of PTI-1 was similar to prostatic carcinoma (p<0.05). CONCLUSION: PTI-1 represented a relatively sensitive marker for prostatic carcinoma and PIN, indicator of prostatic carcinoma progression.

Rabies is a fetal viral encephalitis to which all mammals, including man are susceptible. This virus, the genus of Rhabdovirus, is usually present in the saliva of infected animals and is transmitted by their bite. As a rule the virus enter the CNS by ascending along peripheral nervous system and extremely variable in extent. Negri bodies are appear in about 75% of cases. These bodies are eosinophilic, usually rounded inclusions and is located in the cystoplasm of the neurons, most frequently in the pyramidal neurons of the Hippocampus and the Purkinje cells of the cerebellum. We have experienced a case of canine rabies that showed Negri bodies in the Purkinje cells along with diffuse degenerative encephalitis and perivascular mononuclear cells infiltration. The Negri bodies were best demonstrated by Negri body staining although routine H-E staind was also useful. There inclusion bodies were located exclusively in the cytoplasm, and were found occasionally. Electron microscopic findings of the Negri bodies showed aggregates of bulletshaped nucleocapsids. We report a Negri body found in the brain of rabid dog with the light and electron microscopic findings.

We present an ultrastructure of an incidentally found renomedullary interstitial tumor also called as medullary fibroma in a 77 year-old female who had a metastatic adenocarcinoma of colon to the ureter. This tumor was a small and grayish white nodule in renal medulla, measuring 0.4 x 0.4 cm. Microscopically the tumor composed of spindle cells, with some vacuolation and intercellular collagen fibers. The electron microscopic observation of the spindle cells reveal that nuclei are spindle to oval shape and cytoplasm contain abundant rough endoplasmic reticulum, polyribosome without microfilaments and cisterna like structures supporting that the renomedullary interstitial cell tumor is renal interstitial cell origin than fibroblasts.

The E-cadherin, alpha-catenin, and beta-catenin expressions were immunohistochemically investigated in paraffin-embedded materials of 80 cases of colorectal adenocarcinomas. The staining similar to normal colorectal mucosa with preserved strong membranous staining pattern was considered normal or preserved expression. The X2 test was used to analyse the statistical correlation of cadherin/catenin expression with clinicopathologic parameters and the Breslow test for the correlation with survival length. Normal colorectal mucosa showed strong membranous expression of cadherin/catenin complex. The reduced E-cadherin, alpha-catenin, and beta-catenin expression were found in 53/80 (66.3%), 46/80 (57.5%), and 44/80 (55.5%) cases of colorectal cancers examined, respectively. There were significant correlations between E- cadherin and alpha -catenin (p=0.035), and between alpha-catenin and beta-catenin (p=0.013). The reduced E-cadherin expression was associated with histologic dedifferentiation, tumor depth, lymph node metastasis, clinical stage (p<0.05), poor clinical outcome in stage II (p=0.016) and the reduced alpha-catenin expression with lymph node metastasis and clinical stage (p<0.05). Reduced expression of two or more proteins was correlated with lymph node matastasis, histologic dedifferentiation, clinical stage, and survival (p<0.05). The present study demonstrates a significant down-regulation of E-cadherin and alpha-catenin expression in colorectal cancer is associated with tumor invasiveness, histologic dedifferentiation, lymph node metastasis, and clinical stage. These results suggest that E-cadherin and alpha-catenin may be useful markers of invasiveness, lymph node metastatic potential, and clinical stage and of value as prognostic markers in the earlier stage. Further studies are needed to confirm the prognostic value of these cadherin/catenin complex.

BACKGROUND: DNA topoisomerase II-alpha is linked with active cell proliferation in mammalian cells. The aim of this study was to examine the relationship between the expression of DNA topoisomerase II-alpha as a proliferating marker, and the expression of Ki-67 and apoptosis in urothelial carcinoma of urinary bladder based on World Health Organization/International Society of Urological Pathology (WHO/ISUP) consensus classification. METHODS: 73 urothelial carcinomas of the urinary bladder after transurethral resection and 25 carcinomas after radical cystectomy were investigated for histologic grading based on WHO and WHO/ISUP consensus classification. Formalin fixed, paraffin embedded tissue of 98 specimens from 73 patients were immunohistochemically stained for DNA topoisomerase II-alpha and Ki-67, and in situ TdT-mediated dUTP-biotin nick end labeling method for evaluation of apoptotic cells was performed. For each case, a DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were determined. RESULTS: The histologic grades of 73 cases based on the WHO grading system were 21.9% (16 cases) in grade 1, 65.8% (48 cases) in grade 2, and 12.3% (9 cases). 5.5% (4 cases) of papillary neoplasm of low malignant potential, 47.9% (35 cases) of urothelial carcinoma of low grade, and 46.6% (34 cases) in urothelial carcinoma of high grade were reclassified using the WHO/ISUP consensus classification. Histologic grades based on two grading systems were correlated to invasion and stage (p<0.05). DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were correlated to histologic grades based on two grading system and invasion. Also, the correlation of DNA topoisomerase II-alpha and Ki-67 indices, and DNA topoisomerase II-alpha and apoptotic indices were significant, respectively. CONCLUSIONS: DNA topoisomerase II-alpha appears to be an useful marker for assessing the proliferation potential of urothelial carcinoma of in the urinary bladder.

An experimental studies were carried out to observe the protective effects of malotilate, a new antihepatotoxic agent, on the chronic hepatic injury induced by CCl4 with or without ethanol. The rats used weighed about 200g were divided into 2 groups, 4 weeks & 8 weeks. Each group was given by orally with malotilate, 100 mg/kg, once a day, and was injected by subcutaneously with CCl4 1.5 mg/kg in a mixture with olive oil twice a week. Aqueous ethanol (20%) was administered in drinking water daily. The serochemical and histopathological studies were carried out in each experimental group. The results were as follows: 1. The chronic liver injuries induced by CCl4 with or without ethanol were significantly ameliorated by normalize serum values GOT, GPT. Alkaline phosphatase, Cholesterol, HDL-Cholesterol, and gamma glutamyl transpeptidase. 2. In Group of 4 weeks, malotilate manifested protective effects by significant inhibition of fatty changes, spotty necrosis and fibrosis in CCl4-intoxicated liver with or without additional ethanol. 3. In group of 8 weeks, malotilate significantly imoproved fatty changes, fibrogenic activity in the group administered with CCl4, followed by ethanol.

OBJECTIVES: MDM-2 is an oncoprotein that inhibits p53 tumor suppressor protein. Amplication and over- expression of its protein have been observed in human malignancies, and these abnormalities have a role in tumorigenesis through inactivation of p53 function. To elucidate the role of p53 and MDM-2 protein in cervical neoplasia we investigated the expression rates of MDM-2 and p53 protein in surgically resected specimens. METHEDS: Immunohistochemical studies using anti-p53 and anti-MDM-2 protein in the paraffin embedded section of 62 cases including cervical intraepithelial neoplasm(CIN) and invasive cervical cancer were performed. RESULTS: Expression rates of p53 protein were 25% in CIN I& CINII, 20% in CINIII, and 44% in invasive carcinoma, respectively. The MDM-2 protein were 33% in CIN I & CIN II, 16% in CIN III, and 48% in invasive carcinoma, respectively. There was no evident correlation between p53 positivity and MDM-2 positivity(p>0.05). However, correlation between MDM-2 negativity and p53 negativity was statistically significant(p=0.002) CONCLUSION: These data suggest that the expression of p53 protein is presumed to be necessarily correlated with MDM-2 protein expression in cervical neoplasia.
