BACKGROUND
The aim of study was to determine the relative frequency of malignant lymphoma according to World Health Organization (WHO) classification in Korea.
METHODS
A total of 3,998 cases diagnosed at 31 institutes between 2005 and 2006 were enrolled. Information including age, gender, pathologic diagnosis, site of involvement and immunophenotypes were obtained.
RESULTS
The relative frequency of non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) was 95.4% and 4.6%, respectively. B-cell lymphomas accounted for 77.6% of all NHL, while T/natural killer (T/NK)-cell lymphomas accounted for 22.4%. The most frequent subtypes of NHL were diffuse large B-cell lymphoma (42.7%), extranodal marginal zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (19.0%), NK/T-cell lymphoma (6.3%) and peripheral T-cell lymphoma (PTCL), unspecified (6.3%), in decreasing order. The relative frequency of HL was nodular sclerosis (47.4%), mixed cellularity (30.6%), and nodular lymphocyte predominant (12.1%) subtypes. Compared with a previous study in 1998, increase in gastric MZBCL and nodular sclerosis HL, and slight decrease of follicular lymphoma, PTCL, and NK/T-cell lymphoma were observed.
CONCLUSIONS
Korea had lower rates of HL and follicular lymphoma, and higher rates of extranodal NHL, extranodal MZBCL, and NK/T-cell lymphoma of nasal type compared with Western countries. Changes in the relative frequency of lymphoma subtypes are likely ascribed to refined diagnostic criteria and a change in national health care policy.

Abstract PDF

BACKGROUND
Triple negative breast cancer (TNBC) is defined as a lack of the expression of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 in breast cancer. Many TNBCs show a profound infiltration of tumor infiltrating lymphocytes (TILs). It is still uncertain whether these TILs are protumoral or antitumoral. Regulatory T cells (Tregs) play a role in inducing immune tolerance to antigens, and they may be selectively recruited by cancer cells. This study was conducted to evaluate the significance of TILs with an emphasis on forkhead box p3 (Foxp3), which is a marker for CD25+CD4+ Treg in TNBC.
METHODS
We investigated the Foxp3, CD8 and CD4 expressions in 100 cases of TNBC by immunohistochemistry and using a tissue microarray. The Foxp3 expression was divided as the high and low infiltration groups (cut-off value=20).
RESULTS
The high infiltration group was correlated with higher histologic and nuclear grades. However, Foxp3+ Tregs were decreased in the T3 and T4 TNBCs as compared to that of the T1 and T2 TNBCs. No significant differences were found for the nodal status, lymphovascular invasion, stage, recurrence and overall survival.
CONCLUSIONS
High Foxp3+ Treg infiltration in TNBC is correlated with the nuclear and histologic grades, but there was no relation to recurrence and overall survival.

Abstract PDF

BACKGROUND
This study was done to see if there were correlations between anatomic and molecular parameters such as microvessel density (MVD), lymphatic vessel density (LVD), and vascular endothelial growth factor receptor (VEGFR)-3 expression and various clinical parameters for papillary thyroid carcinomas of size > 1.0 cm (PTCs) and size < or = 1.0 cm (papillary thyroid microcarcinomas, PTMCs). PTMCs were divided into two subgroups (0-5 mm and 6-10 mm).
METHODS
We analyzed 197 thyroid carcinomas including 113 PTCs and 84 PTMCs. Tissue samples form 30 patients from each group matched for clinical characteristics were selected for immunostaining.
RESULTS
Although PTCs and PTMCs showed significant differences in clinical characteristics, they did not show significant difference in MVD, LVD, or VEGFR-3 expression. There was a significantly higher LVD in the PTMC subgroup with the larger tumors but no difference in clinical characteristics. LVD was higher in patients > 45 years old (more apparent in the PTC group) and LVD had suggestive correlations with multicentricity and extrathyroidal extension depending on analytic conditions.
CONCLUSIONS
Since LVD showed variable correlations with clinical variables for papillary carcinoma of the thyroid depending on analytic conditions, the individually planned treatments based on overall clinicopathological factors are advised.

Abstract PDF

BACKGROUND
The Hematopathology Study Group of the Korean Society of Pathologists conducted a nation-wide retrospective analysis of Korean pediatric lymphoma, to provide pathologic data on pediatric/adolescent lymphoma subtypes and features.
METHODS
All lymphoma cases of all age groups were collected during a recent 2 year-period (2005-2006) from 32 institutes in Korea. Among 3,686 lymphoma patients, 142 who were age 18 or less were classified according to the World Health Organization (WHO) classification.
RESULTS
Among 142 pediatric/adolescent lymphoma patients, Hodgkin lymphoma accounted for 21 (14.8%) and non-Hodgkin lymphoma (NHL) for 121 (85.2%). Hodgkin lymphoma appears to be more common in the pediatric/adolescent age group than in the all-ages group (14.8% vs 4.4%). T- and natural killer cell-NHL was more common in the pediatric/adolescent age group than in the all ages group (46.3% vs 22%). The majority of Korean pediatric/adolescent NHL cases was composed of Burkitt lymphoma, T- or B-lymphoblastic lymphoma, anaplastic large-cell lymphoma, and diffuse large B-cell lymphoma. For lymphoma patients under the age of 6 years, most had B-lymphoblastic or Burkitt lymphoma, which commonly presented at extranodal sites.
CONCLUSIONS
The distribution of lymphoma subtypes in the pediatric/adolescent age group is quite different from the distribution of adults, but it was quite similar to distribution in Western countries.

Abstract PDF

BACKGROUND
Regulatory T cells (Tregs) may contribute to the immunological hyporesponsiveness against hepatitis B virus (HBV), and this can result in chronic infection. Tregs suppress the T cell responses directed against HBV and they protect hepatocytes by down-regulating the immune responses that cause liver damage, but the role of Tregs has not been well characterized.
METHODS
Fifty four patients were selected and classified into three groups (12 were in the immune-tolerance phase, 35 were in the immune-clearance phase and 7 were in the asymptomatic virus carrier phase). We examined the frequency of CD3+, CD4+ & CD8+ T cells and forkhead box P3 (FoxP3)+ Tregs in the needle-biopsied liver tissue by performing immunohistochemistry.
RESULTS
The FoxP3+ Tregs were mainly located at the portal tracts. In the immune-clearance phase, the frequency of FoxP3+ Tregs was significantly increased compared to that of the immune-tolerance group and the asymptomatic carrier group. Increased FoxP3+ T cells were observed in the patients with a higher histologic inflammatory index. No correlation was observed among the numbers of FoxP3+ Tregs, the serum alanine aminotransferase level, detection of HBeAg and the HBV-DNA viral load.
CONCLUSIONS
FoxP3+ Tregs may play important roles in suppressing the immune response to HBV and the complete elimination of HBV.

Abstract PDF

BACKGROUND
This study was done to obtain comprehensive data on changes in the structural components of the enteric nervous system in pediatric patients with intestinal pseudo-obstruction (IPO). We evaluated routinely processed, in formalin-fixed tissues by quantitative morphometric analysis. In addition, we used formalin-fixed tissue to explore the possibility of using previously proposed diagnostic criteria to evaluate frozen serial sections for intestinal neuronal dysplasia (IND) type B and hypoganglionosis.
METHODS
We analyzed data for 19 IPO cases. Morphometric analysis for quantification of ganglia and ganglion cells (GCs) was done for the myentric and the submucous plexus. In addition, we determined the presence of immature GCs and the distribution of nerve fibers and interstitial cells of Cajal (ICC).
RESULTS
Nine patients showed combined hypoganglionosis, IND, and decreased ICC; others showed various combinations of these. Several morphometric factors were significantly different between patient groups as well as being different than the control group.
CONCLUSIONS
Our pediatric IPO cases showed extensive overlapping of pathological findings. And the findings suggest the utility of using previously proposed morphometrically measured factors in multiple frozen sections as diagnostic criteria for IND type B and hypoganglionosis in formalin-fixed tissue.

Abstract PDF: The brown bowel syndrome (BBS) is an uncommon disorder, which is characterized by brown pigmentation of the intestine due to the accumulation of lipofuscin in the smooth muscle cells. Vitamin E deficiency has generally been considered as the cause of this malady. BBS has been reported in a wide variety of malabsorptive diseases involving the pancreas, liver and gastrointestinal tract. We report here on a case of brown bowel syndrome that occurred in a 73-year-old man who had undergone total gastrectomy 11 years ago for gastric adenocarcinoma. He has complained about intestinal obstructive symptoms for several years, and these symptoms were recently aggravated. He showed a low serum concentration of total protein, albumin and cholesterol, and he had been treated for megaloblastic anemia due to vitamin B12 and folate deficiency several months ago. The resected small bowel showed lipofuscin deposition in the muscle layer of the intestine and large vessels. The electron microscopic examination revealed multiple electron dense lipofuscin deposits with irregular shapes and sizes in the cytoplasm.

Abstract PDF: BACKGROUND
Hypoxia-inducible factor-1alpha (HIF-1alpha) is an intrinsic marker of tumor hypoxia, and this is associated with reduced radiosensitivity. Furthermore, HIF-1alpha can increase a tumor's aggressiveness by promoting neoangiogenesis, cell proliferation and survival, and invasion.
METHODS
The expression of HIF-1alpha was was investigated by performing immunohistochemistry on the cervical tissue specimens obtained from 57 patients who had received radiotherapy combined with or without chemotherapy for stages I-III cervical squamous cell carcinoma. The staining results were compared with anemia, the stage, the radiotherapy response and patient survival by univariate and multivariate analysis.
RESULTS
In 57 patients, the expression of HIF-1alpha was seen in the tissue specimens of 46 patients (81.7%). Among them, 25 (54.3%), 14 (30.4%), and 7 (15.2%) of the patients' tissue specimens showed weak, moderate and strong expressions, respectively. Six patients had a partial response after radiotherapy. Twelve patients (21.1%) died of cervical cancer. The increased expression of HIF-1alpha was significantly associated (p<0.05) with the disease stage and anemia. There were significant positive correlations between the increased expression of HIF-1alpha and the poor response after radiotherapy and the patients' survival.
CONCLUSIONS
The present result suggests that the overexpression of HIF-1alpha in the uterine cervix could be used as a prognostic indicator for the patients treated with radiotherapy.

Abstract PDF: Background
: PTEN, located on chromosome 10q23.31, is a novel tumor suppressor gene. In the sporadic breast cancers, the incidence of the loss of heterozygosity of PTEN is approximately 10% to 40%, but the incidence of intragenic mutation of PTEN is less than 1%. To as- sess the role of the PTEN in the invasive ductal breast cancer, we studied the frequency of the loss of PTEN expression, its correlation with the commonly used prognostic factors of the breast cancer and with PTEN promoter hypermethylation status. Methods : Immunohistochemical staining with an anti-PTEN protein antibody was performed on the paraffin-embedded breast tissues from 129 women with a diagnosis of invasive ductal carcinoma. Methylation specific PCR was performed to detect hypermethylation in the PTEN gene on the 28 cases with the loss of PTEN expression.
Results
: Sixty-two (48%) of 129 breast tumors had the loss of PTEN expression. The loss of PTEN expression was correlated with lymph node metastasis and stage, and there was a near-significant correlation with the tumor size. PTEN promoter hypermethylation was found in five (18%) out of 28 patients. Conclusion : These results suggest that the loss of PTEN expression might play a role in the progression of the breast cancer and that the aberrant promoter methylation is one of the silencing mechanisms of PTEN.

Abstract PDF: BACKGROUND
Human herpesvirus 8 (HHV-8) has been strongly implicated in the etiopathogenesis of multiple myeloma. Cytokines, especially interleukin-6, that are produced by HHV-8 infected bone marrow stromal cells may play a role in the proliferation of neoplastic plasma cells. Viral DNA sequences have been detected in the bone marrow and peripheral blood cells of myeloma patients. Yet some investigators have not found the same results.
METHODS
We exmined the presence of HHV-8 DNA in the paraffin-embedded cell block specimens of bone marrow aspirations from 26 patients with multiple myeloma by polymerase chain reaction (PCR) with KS330(233) primers. Thirteen cases of bone marrow aspirations from patients with other diseases were used as a negative control. The DNA extracted from the BC-1 cell line was used as a positive control. Immunohistochemistry using commercially available HHV-8 antibody was done in the cases that were proven HHV-8 DNA-positive by PCR.
RESULTS
One case (3.9%) among the 26 patients with myleoma was positive for HHV-8 DNA by PCR, but no positive cells were detected in this case by immunohistochemistry.
CONCLUSIONS
We could not find a clear relation between myeloma and HHV-8 in Korean patients examined in the present study.

RUNX3 Methylation Status in Colonic Carcinoma and Adenoma.: Shi Nae Lee, Min Sun Cho, Woon Sup Han; Korean J Pathol. 2004;38(1):42-45.

Abstract PDF: BACKGROUND
RUNX3 is expressed throughout the luminal gastrointestinal tract. RUNX3 is on chromosome 1p36, a location considered to carry an important tumor suppressor for many types of cancers. Epigenetic silencing of RUNX3 is causally related to human gastric cancer.
METHODS
Colorectal cancers, adenoma, and the corresponding normal mucosa were obtained from 26 individual patients. To identify methylation of RUNX3 in colonic carcinogenesis, methylation-specific PCR was performed.
RESULTS
RUNX3 methylation was found in one case of colonic carcinoma. The normal mucosa and tubular adenoma of this case had no methylation. No other cases were found to have methylations.
CONCLUSIONS
These results are very different from the findings of gastric carcinomas, where frequent DNA methylation in the vicinity of the RUNX3 promoter is found. Although, the possibility of a role of RUNX3 methylation in the colon can not be completely ruled out, these results suggest that methylation of the RUNX3 promoter region might not contribute to the adenoma-carcinoma sequence of the colon.

Abstract PDF: BACKGROUND
TB-PCR is a faster and more sensitive method to detect mycobacterium than acid-fast bacilli (AFB) stain, which is laborious and time consuming. We compared the sensitivity and specificity of AFB stain and TB-PCR and examined the possibility of TB-PCR as a confirmative test without AFB stain in the diagnosis of tuberculosis.
METHODS
We performed Ziehl-Neelsen stain and nested PCR using a commercially available TB-PCR kit amplifying IS6110 sequence in 81 cases of paraffin-embedded tissues diagnosed as chronic granulomatous inflammation. In addition, we evaluated the morphology of granuloma and the presence of caseation necrosis.
RESULTS
Of the 81 cases studied, 22 (27.2%) and 40 (49.4%) were positive for AFB stain and TB-PCR, respectively. Of 49 cases accompanying caseation necrosis, 19 (38.8%) were AFB stain positive and 37 (75.5%) were TB-PCR positive; a result that is comparable with that of other reports. Of the 22 AFB-positive cases, 2 were TB-PCR negative.
CONCLUSION
TB-PCR is very helpful for the diagnosis of tuberculosis in routinely processed, formalin-fixed, paraffin-embedded tissue samples. Nevertheless, AFB stain should continue to be performed at the same time.

Abstract PDF: BACKGROUND
KAI-1 is a metastasis suppressor gene. We have evaluated the correlationbetween KAI-1 protein expression in ductal carcinomas of the breast and axillary lymph nodemetastasis.
METHODS
The expression of KAI-1 protein was confirmed by immunohistochemistryto examine breast tissues of ductal carcinomas from 50 patients with nodal metastasisand from 53 patients without metastasis. Western blot analysis was performed on fresh frozenbreast tissues from 17 cases with nodal metastasis and from 19 cases without metastasis.
RESULTS
Immunohistochemical KAI-1 protein expression was decreased or negative in 39out of 50 cases with metastasis (78%), compared with 8 out of 53 cases with no metastasis(15.1%). The difference was statistically significant (p<0.05). Immunohistochemical KAI-1protein expression was significantly decreased in cases with higher modified Black's nucleargrade (p=0.027) and larger tumor size (p=0.039). Western blot analysis showed positivebands at 29.5 kDa in 8 out of 19 cases without metastasis (42.1%), and none of the 17 caseswith metastasis showed positive bands (p=0.0024).
CONCLUSION
These results suggest thepossibility that KAl-1 might play a major role of a metastasis suppressor gene in addition tothe part it plays in the growth and progression of human breast ductal carcinoma. In addition, the decreased expression of KAI-1 protein in breast ductal carcinomas could be used as afactor suggesting poor prognosis.

Abstract PDF: BACKGROUND
Hepatocellular cholestasis denotes the alteration of bile secretion by hepatocytes. The causes, degree of hepatocyte injury and concomitant bile duct loss are considered to influence the clinical course.
METHODS
The causes and pathological features of hepatocellular cholestasis were analyzed in 62 cases of liver biopsies; and the causes of primary biliary cirrhosis, primary sclerosing cholangitis, and biliary obstruction were not included.
RESULTS
The mean age of the patients was 42.2 years, and the ratio of male to female was 1.8:1. Fifty-eight cases (94%) showed cholestatic hepatitis, and 4 cases (6%) showed pure cholestasis without hepatitis activity. The majority of the cases (52 cases, 84%), including 19 cases of herbal medicine, was related to drugs. Loss of bile duct was found in 12 cases (19%), which were all cases of chronic cholestasis. All of them had drug histories, including 9 cases of herbal medicine. Clinical follow-up was performed in 9 out of the 12 cases with bile duct loss, and all of them showed elevated total bilirubin and/or alkaline phosphatase levels for more than 6 months.
CONCLUSION
Drugs are the major cause of hepatocellular cholestatic hepatitis/cholestasis; and information about drugs, including herbal medicines, should be considered for proper evaluation of liver biopsy with hepatocellular cholestasis. Bile duct loss should be evaluated in the cases of chronic hepatocellular cholestasis, especially in drug induced cases.

Abstract PDF: Pulmonary vascular hypertension is characterized by migration and proliferation of smooth muscle cells accompanying abnormal synthesis and accumulation of extracellular proteins in vascular wall. The aim of this study is to define the role of endogneous TGF-betas and PDGF in the process of remodeling vessels through determining the temporal and spatial distribution of these growth factors in hypertensive pulmonary vessels in monocrotaline-induced pulmonary hypertension in rat. Sprague-Dawley rats were sacrificed 12 hours, 1, 2, 4, 7, 10, 14, 21, 28, and 56 days after treatment. The morphometric analysis of medial thickening and immunohistochemical study using antibodies to TGF-beta1, TGF-beta2, TGF-beta3, and PDGF were performed. Immunoreactivities for TGF-beta1 and TGF-beta3 were increased from the 14th day in the medial smooth muscle cells and PDGF showed increased expression from the 21st day in the medial smooth muscle cells. No difference in TGF-beta2 immunoreactivity was found between control and experimental groups. The expression of TGF-beta1, TGF-beta3 and PDGF increased in medial layers with the progressive thickening of pulmonary arteries which was considered to have close relation to medial hypertrophy of pulmonary arterioles. In the case of PDGF, however, the morphologic change occurred before increase in immunoreactivity was observed in the medial layer of pulmonary arterioles. Moreover, the function of isoforms of TGF-beta has yet to be completely elucidated; the different affinity to receptors and the degree of expression of these receptors that are supposed to affect the function of growth factors. Thus, further studies are needed.

Abstract: We reviewed eight solitary fibrous tumors occurring at sites other than pleura (three orbit, two retroperitoneum, one each hard palate, thyroid, and tongue) which shared the histologic and immunohistochemical features of solitary fibrous tumors of pleura. Six patients were women, and two were men, aged from 26 to 74 years. The tumors ranging from 1.5 to 19 cm in diameter presented as well-circumscribed, unencapsulated, soft to rubbery tissue masses. Histologically they were characterized by a proliferation of spindle or ovoid cells intervened by a dense bundles of collagen. A variety of growth patterns was identified but the so-called patternless pattern was the predominant one. One tumor exhibited highly cellular sarcomatous areas with extensive necrosis, which was diagnosed as malignant solitary fibrous tumor. Immunohistochemical studies showed that all of the tumors were strongly positive for both CD34 and vimentin, but negative for cytokeratin, S-100 protein, EMA, and desmin. One case examined ultrastructurally showed features of fibroblast. All but one showed no evidence of recurrence or metastasis over follow-up period of 14 to 32 months. We conclude that extrapleural solitary fibrous tumors represent a distinct mesenchymal tumor with variable histologic features and should be differentiated from other spindle cell mesenchymal tumors.

Abstract PDF: Taxol is an active chemotherapeutic agent against a variety of solid tumors and a potentially useful drug for augmenting the cytotoxic action of radiotherapy against certain cancers. Taxol blocks cells in the mitotic phase of cell cycle. The aim of this study was to define the in vivo response of rapidly dividing cells of the small intestinal mucosa to taxol. We studied the numbers of apoptotic and mitotic cells and the expression of bcl-2 and p53 in rat jejunal crypt cells at 1, 2, 4, 8, 12, 16, and 24 hours and 3 and 5 days after intraperitoneal injection of taxol. Mitosis peaked at 2 and 4 hours and 12 and 16 hours. Apoptosis peaked at 16 hours and returned to normal after five days. The glands in crypts showed marked distortion with atypical lining cells after three days, which returned to normal at 5 days. bcl-2 expression was markedly decreased at 8 to 24 hours and subnormally recovered after three to five days. p53 showed no significant changes throughout. The histopathological changes in small intestine due to taxol were transient with complete recovery. bcl-2 expression was inversely corresponded to numbers of apoptosis. The changes were p53 independent. Further studies to understand the conditions that maximize the cell-cycle modulating effects of taxol cl-may greatly enhance its anti-tumor effectiveness.

Abstract: Gastrointestinal stromal tumor (GIST) is known as considerable controversal tumor about it's histogenesis, differentiation and biologic behavior. It is traditionally regarded as smooth muscle tumor. To evaluate and clarify the origin of tumor, we performed immunohistochemical study of 23 cases of GIST on CD34 antigen, alpha-smooth muscle actin, S-100 protein, and compared the result with 4 cases of typical leiomyoma of GI tract. The results were as follows. CD34 antigen expression was noted in 21 cases (91.3%) of GIST, while typical leiomyoma was all negative. There were no difference of CD34 expression according to the biologic behavior. However, it's staining pattern was significantly different (p<0.05). Focal or multifocal expression was dominant in benign GIST (58.3%), while diffuse expression was dominant in malignant GIST (80%). Actin was expressed in 5 cases of benign GIST (38.5%) and 1 of malignant GIST (16.7%) focally. All typical leiomyoma showed diffuse strong positivity on alpha-smooth muscle actin. S-100 protein was expressed in 2 cases of benign GIST (16.7%) only. The pattern of CD34 expression was focal in the actin or S-100 protein positive cases. In conclusion CD34 antigen is useful marker in the separation of GIST, from typical smooth muscle tumor. Also it suggest that most GISTs are histogenetically primitive mesenchymal cell origin. However, CD34 expression was unrelated with biologic behavior of GIST.

Abstract: It is well documented that cardiac myxomas are associated with immunologic features that can simulate systemic autoimmune diseases. Recently, it was reported that cardiac myxomas produce IL-6 constitutively, which could partly explain the immunologic features observed in these patients. However, only a few investigators have studied cytokines in regards to symptoms they may cause in patients with cardiac myxoma. Also there is very little information in the literature on the immunohistochmical localization of IL-6. We performed immunobistochemical stains for IL-4, TNF, and IL-6 on paraffm embbeded tissue of cardiac myxoma tissue. A bioassay of IL-6 activity in patient's serum and in cultured cells from fresh myxoma tissue was performed to ascertain the role of these cytokines in myxomas. In this study, we demonstrated inununohistochemically that there was a local overproduction of IL-4, TNF, and IL-6 in cytoplasm of the tumor cells in about half cases. Bioassays of the serum and cultured tumor cells revealed elevated IL-6 activities. Also these findings correlate to production of patient's constitutional symptoms with statistical significance (P<0.05). In conclusion, these results are of considerable importance in understanding the role of IL-4, TNF, and IL-6 in cardiac myxoma patient with constitutional symptoms, and have an impact on strategies for diagnosis and therapy of cardiac myxoma.

Abstract PDF: Viral myocarditis is considered an important cause of dilated cardiomyopathy. At preseent, two mechanisms are known to be involved in the pathogenesis of viral myocarditis and subse-quent cardiomyopathy: viral direct toxicity and immune mediated toxicity. Some authors have reported that IL-6 influences the immunologic mechanism and the virus-induced tissue damage in myocarditis. We injected encephalomyocarditis(EMC) virus to induce viral myocarditis in ICR mice. In order to study the lymphocyte subset and IL-6 expression to clarify the immune mechanism and to demonstrate the role of IL-6 in viral induced myocardial damage. The following results were obtained: 1) In virus inoculated mice, inflammation was severest at 10 days, and some serious complications developed, indicating a possible transition to dilated cardiomyopathy. 2) On analysis of the lymphocyte subset, CD4 cells were most prevalent at 5 days and CD8 cells were most prevalent at 10 and 20 days. 3) IL-6 was significantly increased and expression of IL-6 was constant, but its intensity was strongest at 5 days. In conclusion, IL-6, produced by inflammatory cells, fibroblasts, and endothelial cells, might play an important role in myocardial damage in experimentally induced EMC viral myocarditis by its direct cytotoxicity or cytokine mediated activation of cytotoxic cells.

Abstract PDF: Cancer of the cervix is the most common malignancy in women in developing countries and the second most common cancer in women throughout the world with approximately 500,000 new cases each year. Prevention of this large number of premature deaths among women is, therefore, a goal worthy of urgent and serious consideration. In this thesis, an automatic cancerous nucleus detection method essential to a screening system with Papanicolaou stained specimens called Pap-smear is proposed which employs image processing techniques. It uses edge information to segment objects and morphologic as well as densitometric information to distinguish cancerous nuclei from dirts or normal nuclei. It has produced useful results in our study.

Abstract PDF: Three cases of subacute necrotizing lymphadenitis diagnosed by fine needle aspiration(FNA) of enlarged lymph nodes are reported. The FNA smears contained randomly activated lymphoid cells, necrotic debris and histiocytes. The same patterns were found in subsequently examined excised lymph nodes from these cases. The differential diagnosis of this entity is discussed and the value of preparing FNA cell blocks and accompanying AFB stain with culture is emphasized.
