This study examined people over 60 years old living in Gumi, Gyeongbuk Province and their health and disease were analyzed. The results are as followings; First, as for seniors' condition of health, females were worse than males: the older they were and the lower their schooling and income were, they recognized bad health condition. Second, as for seniors' health care, males cared for themselves better than females: the higher their schooling and income were, the better they cared for themselves. Using the methods of health care such as walking, hiking, diet care, We found out that the low income class did not get the health examination at all. Lastly, as the most seniors in Gumi city suffer a chronic disease, the city office is needed to promote various policies like prevention of age-related disease, early discovery and delay of retrogression at its own initiative.

Ultrasound (US) is an attractive diagnostic approach to identify both common and uncommon nipple pathologies, such as duct ectasia, nipple abscess, nipple leiomyoma, nipple adenoma, fibroepithelial polyp, ductal carcinoma in situ (restricted to nipple), invasive carcinoma, and Paget's disease. US is the reliable first-line imaging technique to assess nipple pathologies. It is useful to identify and characterize nipple lesions. Additionally, we have presented the mammography and MRI outcomes correlated with histopathologic features for the relevant cases.

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.

Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous disease. Not all patients with COPD respond to available drugs. Identifying respondents to therapy is critical to delivering the most appropriate treatment and avoiding unnecessary medication. Recognition of individual patients' dominant characteristics by phenotype is a useful tool to better understand their disease and tailor treatment accordingly. To look for a suitable phenotype, it is important to understand what makes COPD complex and heterogeneous. The pathology of COPD includes small airway disease and/or emphysema. Thus, COPD is not a single disease entity. In addition, there are two types (panlobular and centrilobular) of emphysema in COPD. The coexistence of different pathological subtypes could be the reason for the complexity and heterogeneity of COPD. Thus, it is necessary to look for the phenotype based on the difference in the underlying pathology. Review of the literature has shown that clinical manifestation and therapeutic response to pharmacological therapy are different depending on the presence of computed tomography-defined airway wall thickening in COPD patients. Defining the phenotype of COPD based on the underlying pathology is encouraging as most clinical manifestations can be distinguished by the presence of increased airway wall thickness. Pharmacological therapy has shown significant effect on COPD with airway wall thickening. However, it has limited use in COPD without an airway disease. The phenotype of COPD based on the underlying pathology can be a useful tool to better understand the disease and adjust treatment accordingly.

Gastrointestinal stromal tumor (GIST) is a mesenchymal tumor and is associated with a specific immunophenotype index. It is very important to identify the specific immunophenotype and the diagnosis for the treatment GIST patients. Ninety two cases of GIST analyzed in this study were immuno-stained for c-kit, DOG1, CD34, PKC-${\theta}$, PDGFR-${\alpha}$. The rate of positive staining and statistical significance were then compared. In addition, the GISTs were analyzed as followings: very low risk, low risk, intermediate risk and high risk according to tumor size and nuclear division, and later correlated with clinical parameters. The results of the GIST positive stainings were: DOG1 (95.7%), PKC-${\theta}$ (90.2%), PDGFR-${\alpha}$ (88.0%), c-kit (87.0%) and CD34 (71.7%). Only DOG1 staining showed a statistical significance of p<0.05. It was identified in the classification system of histologic risk that staining expression of DOG1, PKC-${\theta}$, PDGFR-${\alpha}$ were significantly increased as histologic risk increases (p<0.05). However, clinical parameters such as age and sex of patients have no correlations with the classification system of histologic risk (p>0.05). Therefore, in this study, the expression of DOG1 showed statistical significance and DOG1, PKC-${\theta}$, PDGFR-${\alpha}$ staining increased significantly as the histologic risk increases in histologic classification system. Taken together, the DOG1 staining should be very effective for the diagnosis of GIST patients.

Background: The objectives of this study were to evaluate the expression of brain and acute leukemia, cytoplasmic (BAALC) gene and erythroblast transformation-specific related gene (ERG) in de novo cases of acute myeloid leukemia (AML) and identify roles in disease progression and outcome. Materials and Methods: This study included 50 newly diagnosed AML patients, along with 10 apparently healthy normal controls. BAALC and ERG expression was detected in the bone marrow of both patients and controls using real-time RT-PCR. Results: BAALC and ERG expression was detected in 52% of cases but not in any controls. There was a statistically significant correlation between BAALC and ERG gene expression and age (p-value=0.004 and 0.019, respectively). No statistical significance was noted for sex, lymphadenopathy, hepatomegaly, splenomegaly, other hematological findings, immunophenotyping and FAB sub-classification except for ERG gene and FAB (p-value=0.058). A statistical significant correlation was found between response to treatment with ERG expression (p-value=0.028) and age (p-value=0.014). A statistically significant variation in overall survival was evident with patient age, BM blast cells, FAB subgroups, BAALC and ERG expression (p-value=<0.001, 0.045, 0.041, <0.008 and 0.025 respectively). Conclusions: Our results suggest that BAALC and ERG genes are specific significant molecular markers in AML disease progression, response to treatment and survival.

Background: The aim of this study was to determine and evaluate the association of different viral infections, with hepatitis B and C viruses, Epstein-Barr virus, cytomegalovirus and human herpes virus-8 (HBV, HCV, EBV, CMV, HHV-8) with the risk of lymphomas (Hodgkin and non-Hodgkin) among Egyptian patients, and correlate with the histopathological staging and typing as well as the prevalence of combined infections. Materials and Methods: A total of 100 newly diagnosed lymphoma patients with 100 healthy age and sex matched normal controls were assayed for viral infection using enzyme linked immunosorbant assay (ELISA) followed by real time polymerase chain reaction (RT-PCR). Results: Our results showed a high statistical significant difference between cases and controls as regards clinical and laboratory findings (P<0.001 and=0.003). A high statistical difference was seen for the association of most viruses and lymphoma cases (p<0.001) except for positive HBs Ag, positive CMV IgG and HHV-8 (p=0.37, 0.70 and 1.0 respectively). No statistical significant difference was found between Hodgkin (HL) and non-Hodgkin (NHL) as regards viral prevalence except HCV antigen, 57.1% for HL and 26.5% for NHL (p = 0.03). Only, HBV DNA showed a high significant value among infiltrated bone marrow cases (p=0.003) and finally, a high significant association of 2 combined viral infections with infiltrated bone marrow lymphoma cases (p=0.04). Conclusions: Our results showed that infection with HBV, HCV, CMV and EBV were associated with increased risk of lymphoma among the Egyptian population. Detection of new associations between infectious agents and risk of cancer development will facilitate progress in elaboration of prophylactic measures, early diagnostic methods and, hopefully, novel therapy of malignant tumours.

Identification of group A $\beta$-phemolytic streptococci is very important to provide an appropriate preventive measure of possible rheumatic fever and acute glomerulonephritis. For such purpose bacitracin susceptibility of streptococci because of its simplity has been most widely used despite of its occasional faulty results. Recently, a coagglutination technique was advocated using streptococcal group specific antibodies adsorbed to protein A-containing staphylococci. This study was conducted to evaluate the coagglutination technique using reagents prepared by ourselves. The specificity, reproducibility and stability were ascertained and the following results were obtained. 1. The identification by coagglutination technique using our own reagent gave the same results compared with the Lancefield precipitation technique. The result also agreed with the Phadebact grouping. 2. There were no variation in group A and B identification due to lot difference. However, there were a few discrepant results in group C and G identification which was conducted in different days with different lots of our reagent. 3. The stability of our reagents was less satisfactory compared to the commercial product. An effort to improve the stability was considered necessary. 4. For coagglutination, it was found convenient to use supernatant of Todd-Hewitt broth incubated for 24 hours. Both parafin-ringed slide glass and RPR card gave comparable results and the former could be used when the latter is not available.

An-11-year-old male Shih-tzu was admitted to emergency care unit of Haemaru Referral Animal Hospital with signs of dyspnea, anuria and depression. There were abnormalities on complete blood count and serum chemistry included leukocytosis with mild left shift, mild azotemia, and increased ALT activity. Fluid therapy(0.9% saline, 40 ml/hr) and antibiotics were immediately initiated. The patient began to vomit after 5 hours' rest and pale mucous membrane, bradycardia, and hypertension were noted. Abdominal ultrasonography revealed enlarged left adrenal gland and thrombus in caudal vena cava(CVC). Result of ACTH stimulation test was normal. Cytology of ultrasound-guided FNA smears showed numerous naked nuclei, which was suggestive of adrenal medullar tumor. Concentrations of 24 hour urine metanephrine and normetanephrine was moderately increased compared to those of a control dog. Adrenal mass was surgically removed, and biopsy of the CVC mass was obtained. After surgery the patient began to recover but the dog acutely developed cardiopulmonary arrest and died. On histopathology the adrenal mass and biopsy of the CVC mass were consistent with pheochromocytoma. On electron microscopic view norepinephrine specific granules were found in the cytoplasm of tumor cells.
