Estrogen and progesterone receptors exist in the epithelial and stromal cells of the endometrium. Proliferative disorders of the endometrium may be associated with autocrine and paracrine actions of estrogen and progesterone in epithelial and stromal cells. This study was performed to evaluate the differences estrogen and progesterone receptor(ER/PR) expression in the epithelial and stromal cells of endometrial hyperplasias and adenocarcinomas using immunohistochemical methods. Immunohistochemical analysis of proliferating cell nuclear antigen(PCNA) was done to evaluate a possible correlation between PCNA and hormone receptor expression. Evaluation was based on samples from 31 simple hyperplasias, 30 complex hyperplasias, and 32 adenocarcinomas. The immunohistochemical expression of ER, PR and PCNA in epithelial and stromal cells were examined according to a scoring system based on the percentage of positive cells and the staining intensity. The results were as follows; 1) The expression of ER and PR in epithelial cells showed a graded, significant decreases in simple hyperplasia, complex hyperplasia and endometrial carcinoma, in that order(ER: P=0.008, PR: P= 0.026). 2) PR expression in the stromal cells showed a significant decrease between hyperplasia and adenocarcinoma(P=0.003). The difference in ER expression was not significant. 3) In stromal cells, the decrease in PR expression was more prominent than the decrease in ER expression when complex hyperplasia was compared to simple hyperplasia. 4) The PCNA expression in simple and complex hyperplasia and adenocarcinoma was not higher than the expression of PCNA in nomal proliferative endometrium. There was no significant difference in PCNA expression between simple and complex hyperplasia and adenocarcinoma(P=0.073). 5) A negative correlation between PCNA and ER/PR expression was not demonstrated in simple and complex hyperplasia, or in adenocarcinoma. Endometrial hyperplasia and adenocarcinoma are probably related to a paracrine action of estrogen and progesterone in epithelial and stromal cells. A progressive loss of PR expression in stromal cells may induce abnormal proliferation of endometrium due to a disrupted hormonal balance.

BACKGROUND: MMP-2 and MMP-9 are involved in the degradation of extracellular matrix, and MMP-2 and MMP-9 expressions in breast carcinomas have been reported as a poor prognostic factor. The aim of this study is to evaluate the prognostic value and the regulatory factors of MMP-2 and MMP-9 expressions in 73 cases of infiltrating ductal carcinomas, NOS type. METHODS: Immunohistochemistry for MMP-1, -2, -3, -9 and TIMP-1, -2 were performed and evaluation for patient? age, size, histologic grade, lymph node metastasis and tumor markers such as ER, PR, p53, c-erbB-2, cathepsin D, MIB-1, and microvessel density was done. RESULTS: The expression rates of MMP-1, MMP-2, MMP-3, MMP-9, TIMP-1 and TIMP-2 were 74.0%, 76.7%, 1.4%, 87.7%, 24.7% and 75.3%, respectively. MMP-2 expression rate was higher in the tumors of low and intermediate grade and PR positive tumors (p<0.05), and MMP-9 expression showed an increasing tendency in ER positive tumor (p=0.0676). Positive relationships between MMP-2 and MMP-1 expressions, and MMP-9 and TIMP-2 expressions were recognized (p<0.05). Conclusion : The prognostic significance of MMP-2 and MMP-9 expressions is still unclear, and MMP-2 and MMP-9 expressions seemed to be positively related with MMP-1 and TIMP-2 expression, respectively.

Immunoglobulin A (IgA) nephropathy in patients with the clinical findings of rapidly progressive glomerulonephritis usually demonstrate crescentic glomerulonephritis (CrGN). It is characterized by mesangial immune complex deposits containing IgA and is rarely associated with ANCA. The following case report illustrates a CrGN with mesangial & capillary wall IgA deposits by immunofluorescence (IF) and mesangial & endocapillary electron dense deposits by electron microscopy (EM) in patient with positive ANCA serology. A 54-year-old male visited due to the discomfort of right flank. Blood pressure was 150/90 mmHg. BUN and serum Creatinine was 40 mg/dL, 4.4 mg/dL respectively. Urinalysis revealed protein 2+, >30 RBC's/ HPF (dysmorphic), 24hr urine protein 1,612 mg/day and creatinine clearance 19 mL/min/1.73m2. Serological P-ANCA was positive by indirect immunofluorescence & ELISA. The histologic findings showed global scleorsis and fibrocelluar crescent without hypercellularity on LM, mesangial IgA deposition on IF, mesangial and subendothelial electrone dense material depositions on EM. After treatment (Methylprednisolon 500 mg/day for 3 days and then prednisolone 60 mg/day), Serum creatinin level, proteinuria and ANCA titer were decreased.

PURPOSE: The purpose of this study was to identify the symptoms and interference of activities of daily living (ADL) of chemotherapy induced peripheral neuropathy (CIPN) in patients receiving taxane and platinums. METHODS: 141 cancer patients were recruited in the cross-sectional survey design. The instruments used in the study was the Chemotherapy-induced Peripheral Neuropathy Assessment Tool (CIPNAT) developed by Tofthagen and colleagues. RESULTS: The patients experienced the symptom and interference of ADL of CIPN moderately. The most common symptom was nerve pain (70.2%) and the patients with high cumulative doses showed a significant of tingling sensation in the feet. Symptom severity increased substantially with cumulative dose of chemotherapeutic agents. CONCLUSION: The results of this study suggest that chemotherapy-induced peripheral neuropathy increase due to repeated chemotherapy and nursing intervention is necessary to reduce symptom severity and interference of ADL of CIPN.

Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently. the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytologic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows: 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2. Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans} type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

The incidence of multiple primary cancers is low than that of single primary cancer. In gastric cancer, incidence of occurrence of multiple primary cancer is 3 to 11.3%. Because stomach and lung are unrelated organs, the combination of gastric cancer and lung cancer is rare. Its estimated incidence is about 10% of all multiple primary cancers. The histologic types of secondary lung cancer in one series, squamous cell carcinomas were 49%; adenocarcinomas were 28%; large cell carcinomas were 14%; small cell carcinomas were 9%; others were 6%. This patient had been diagnosed as early gastric cancer 3 years ago, but he refused operation for cancer and wasnt followed up. After 3 years, he revisited us for dry coughing and diagnosed as small cell lung cancer. At this time, previous gastric cancer was remained as well differentiated, early gastric adenocarcinoma. For its rarity, we report this case with review of literatures.

The purpose of this study was to investigate the perception of foodservice managers in childcare centers and kindergartens for identifying the vulnerable areas of safety management. The foodservice managers in 1,144 of nationwide childcare centers and kindergartens were surveyed from May to October 2007 to answer a total 72 questions in areas of general characteristics, actual practice of foodservice management and safety management perception. Meals were served in 97.7% of surveyed facilities and 91.0% among them were self-operated. The hiring rate (27.8%) of dietitians in childcare centers was significantly lower than the rate (82.0%) of kindergartens. The needs of dietitian employment between childcare centers and kindergartens differed as 44.9% and 87.5%, respectively. In knowledge on food-borne illnesses, they have the wrong information in the field of season for frequent outbreak, major pathogens and foods causing food-borne illnesses. The food-borne illnesses (36.2%) were indicated as the major problem in foodservice facilities and the degree of risk exposure was considered as safe (70.1%). More than 70% of both facilities answered as sanitary in the status of personal hygiene. Only 38.0% recognized the Facility and Equipment Standard in the Childcare Law and Early Childhood Education Law. In preparation of meals and management of cooking processes, kindergarten scored significantly high compared to childcare centers (p < 0.05 or p < 0.01) while the necessity of standards was not different in both facilities. Among managers surveyed, 28.8% had taken food safety education from professional institutions and more than 80% in both facilities indicated the need of professional educations. These results suggest that it is necessary for the systematic sanitary education of foodservice managers by developing the sanitary management standard as well as the amendment of laws related foodservice in childcare centers and kindergartens.

It has been reported that heat shock (43degrees C) induces an episode of cell death in developing central nervous system as part of pathogenesis leading to abnormal growth and development. Cell death induced by heat shock is likely to occur by a process termed apoptosis. On the other hand, protective role of mild heat shock on heat shock-induced apoptosis has also been suggested. In this study, the effect of 43degrees C heat shock on the induction of apoptosis was investigated in detail firstly by determining internucleosomal DNA fragmentation (DNA laddering) and secondly by determining apoptotic bodies using TUNEL (TdT-mediated dUTP-biotin nick end labeling). In addition, the effect of mild heat shock (42degrees C) on the apoptotic process was examined. In order to modulate the environmental temperatures of the developing embryos, we used whole embryo culture technique. DNA fragmentation and apoptotic body was induced a little by 42degrees C exposure but embryos exposed to 43degrees C showed strong DNA fragmentations. In comparison, the amount of DNA fragmentation was significantly reduced in embryos with 42degrees C pretreatment than 43degrees C group. In the control embryos (37degrees C exposure), basal levels of DNA fragmentation and apoptotic bodies were observed. From this study, it was evident that thermotolerance could protect the early postimplantation embryos from hyperthermia.
