심장사상충 감염은 개에서 심부전과 폐질환을 유발하는 치명적인 질환이다. 이러한 심장사상충 감염은 너구리들을 포함한 야생육식동물에서도 발생을 한다. 최근 연구를 통해, 야생 너구리 집단에서 상대적으로 높게 발생하는 유병률을 확인할 수 있다. 그러므로, 본 논문은 한국의 야생너구리에서 발생하는 D. immitis 의 유병률과 감염된 너구리의 회복률에 대한 평가를 하기 위해 고안되었다. 한국 너구리의 D. immitis 에 대한 전체의 유병률은 17.8%이었다. 수컷 너구리의 유병률은 21.8%이었고, 암컷 너구리의 유병률은 12.8% 이었다. 심장사상충 항원 검사에서 양성이 나온 17마리의 너구리들에게 마이크로필라리아는 관찰되지 않았다. 본 논문의 결론은 한국의 D. immitis 의 유병률이 일본에 비해 2배이상 높은 것으로 확인되었다. 또한, 고양이와 마찬가지로 너구리들도 마이크로필라리아혈증이 드문 것으로 나타났다.

Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.

This study was undertaken to observe the relationship between salivary IgA, IgG, agglutinin titer & dental caries. The subjects divided into two groups, an active caries group (AC group) and caries-free and treated caries group (CFTC group). The AC group consisted of 36 subjects who had one or more carious lesions and the CFTC group of 12 subjects who had no evidence of caries or had filled teeth without present carious teeth for the last six months. The IgA, IgG and IgM levels in their saliva were measured by single radial immunodiffusion method using a disposable low-level immunodiffusion plate. The salivary agglutinin titers to Streptococcus mutans were measured by microtitration system. The results were as follow; 1. The mean value of IgA concentration in saliva of AC group was slightly higher than that of CFTC group, but its difference was slight. 2. The mean value of IgG concentration in saliva of AC group was slightly lower than that of CFTC group. The IgM concentration in saliva of both groups was neither below 1.1 mg/dl nor detected on LC partigen immunodiffusion plate. 3. There was no difference in the agglutinin titer to S. mutans antigen by serotypes, but low level agglutinin to type d was measured in both groups. 4. AC group showed low correlation between IgA, IgG & DMFT, but CFTC group revealed negative correlation. 5. The relationship between salivary IgA & agglutinin titers to S. mutans was low correlation in AC group, but CFTC group showed significant positive correlation. (P<0.05) 6. There were no specific correlations among the concentrations of salivary immunoglobulins, agglutinin titers to S. mutans, and the DMF teeth. They had no close concern to induce the dental caries.

An experiment was conducted with twenty crossbred male lambs to assess the effect of cotton (Gossypium) seed meal (CSM) on blood constituents and immunity. Lambs were randomly assigned to a reference diet (30% deoiled peanut meal, DPNM) and four test diets containing 40% of either raw, 45 minutes cooked, 1% $Ca(OH)_2$ and iron (1 free gossy-pol, FG : 0.3 Fe) treated CSM (replacing approximately 50%, reference concentrate mixture). These isonitrogenous and isocaloric concentrate mixtures were fed to meet 80% of protein requirements (NRC, 1985) along with ad lib maize hay for 180 days. Blood was collected at 60, 120 and 180 days post feeding. The lambs were sensitized with Brucella abortus S99 antigen after 140 days and were subjected to ELISA and delayed type hypersensitivity. Blood haemoglobin, erythrocyte count, leucocyte count, total protein, total albumin, total globulin, urea, creatinine concentration and aspartate aminotransferase activity in lambs fed on raw or processed CSM were comparable to the values of reference lambs. The higher (p<0.01) blood glucose levels observed in CSM fed lambs at 60 days of feeding was latter reduced to the levels comparable with those on reference diet at 120 and 180 days of feeding. The alanine amino transferase activity was lower in lambs fed raw and cooked CSM containing diets at 120 and 180 days of feeding. A marginal increase in serum iron and alkaline posphatase activity was observed in iron treated group and raw CSM fed lambs, respectively. The humoral immune response and DTH reactivity was lower (p<0.05) in lambs fed raw CSM (consuming 302.83 mg FG/day). Cooking, $Ca(OH)_2$ and iron treatment of raw CSM showed a positive response in alleviating the suppression of immune response owing to the reduced consumption of FG by 40.19, 17.40% and 26.73%, respectively in these diets. The present study thus indicated that consumption of 40% raw CSM (302.83 mg FG/day) though did not affect majority of the haematological and blood biochemical parameters, but markedly suppressed the immune mechanism of lambs.

Purpose: To study the long-term outcomes and tolerance in our patients who received dose escalated radiotherapy in the early salvage post-prostatectomy setting. Materials and Methods: The medical records of 54 consecutive patients who underwent radical prostatectomy subsequently followed by salvage radiation therapy (SRT) to the prostate bed between 2003-2010 were analyzed. Patients included were required to have a pre-radiation prostate specific antigen level (PSA) of 2 ng/mL or less. The median SRT dose was 70.2 Gy. Biochemical failure after salvage radiation was defined as a PSA level >0.2 ng/mL. Biochemical control and survival endpoints were analyzed using the Kaplan-Meier method. Univariate and multivariate Cox regression analysis were used to identify the potential impact of confounding factors on outcomes. Results: The median pre-SRT PSA was 0.45 ng/mL and the median follow-up time was 71 months. The 4- and 7-year actuarial biochemical control rates were 75.7% and 63.2%, respectively. The actuarial 4- and 7-year distant metastasis-free survival was 93.7% and 87.0%, respectively, and the actuarial 7-year prostate cancer specific survival was 94.9%. Grade 3 late genitourinary toxicity developed in 14 patients (25.9%), while grade 4 late genitourinary toxicity developed in 2 patients (3.7%). Grade 3 late gastrointestinal toxicity developed in 1 patient (1.9%), and grade 4 late gastrointestinal toxicity developed in 1 patient (1.9%). Conclusion: In this series with long-term follow-up, early SRT provided outcomes and toxicity profiles similar to those reported from the three major randomized trials studying adjuvant radiation therapy.

Background: Postoperative carbohydrate antigen 19-9 (CA19-9) is an independent predictor of survival for pancreatic ductal adenocarcinoma (PDAC), and more powerful than preoperative CA19-9. However, making decisions just dependent on postoperative CA19-9 may result in necessary treatments not being performed. Materials and Methods: A total of 178 patients with resected PDAC were eligible for this retrospective study, classified into two corresponding subgroups according to postoperative CA19-9. Prognostic significance of all clinicopathologic factors was evaluated by univariate and multivariate analyses. Results: Postoperative CA19-9, preoperative CA125 and lymph node status were independent predictors. Better predictive performances for overall survival (OS) and recurrence-free survival (RFS) were achieved by postoperative CA19-9 compared to preoperative CA125 and lymph node status. Particularly, preoperative CA125 was associated with poor OS (p<0.001 for the normalized CA19-9 patients, p=0.012 for the elevated) and RFS (p=0.005 for the normalized, p=0.004 for the elevated). Moreover, preoperative CA125 levels related with survival in double-negative patients. Conclusions: Normalization of CA19-9 is not tantamount to be cured. Preoperative CA125 is a critical predictor for PDAC patients, especially in double-negative patients.

Objective: To explore the most appropriate treatment for patients with hepatocellular cancer (HCC) >10 cm by using the Barcelona Clinic Liver Cancer (BCLC) classification. Materials and Methods: A total of 124 HCC patients undergoing surgery were selected. Disease-free survival (DFS), overall survival (OS) and prognostic factors were respectively assessed. Results: This study showed that the cumulative 1-, 3-, 5-year survival rates were 79.7%, 59.8% and 41.6% in BCLC-A patients, 76.2%, 9.5% and 0% in BCLC-B patients and 44.9%, 0% and 0% in BCLC-C patients, respectively. The 1-, 3-, 5-year DFS rates were 49%, 24.5% and 9.1% in BCLC-A patients, 7.5%, 0% and 0% in BCLC-B patients, respectively. No BCLC-C patients survived 1 year after surgery. Multivariate analysis indicated that hepatitis B surface antigen (HBsAg), vascular invasion, intra-hepatic metastasis, curative resection, tumor rupture and pathologic differentiation were independent prognostic factors. Conclusions: Surgery is effective and safe for patients with HCC >10 cm with sufficient hepatic reserve.

Background: This study aimed to evaluate the baseline white blood cell (WBC), neutrophil, lymphocyte, monocyte, basophil, eosinophil count, total prostate-specific antigen (TPSA), free PSA (FPSA) level, neutrophilto- lymphocyte and neutrophil-to-monocyte ratios among patients with prostate cancer and benign prostatic hyperplasia (BPH), as well as healthy individuals. Materials and Methods: 2005-2012 laboratory files of 160 patients with prostate cancer at Kayseri Training and Research Hospital, Oncology Outpatient Clinic, 285 patients who were pathologically diagnosed with BPH in Urology Outpatient Clinic and 200 healthy individuals who were admitted to Internal Medicine Outpatient Clinic were retrospectively analyzed. Baseline WBC, neutrophil, lymphocyte, monocyte, basophil, eosinophil count, TPSA, FPSA level, neutrophil-to-lymphocyte ratio and neutrophil-to-monocyte ratio were recorded and compared across groups. Results: Patients with prostate cancer had a lower lymphocyte level compared to the patients with BPH and healthy controls (p<0.001). The mean monocyte count, leukocyte-to-monocyte ratio, and leukocyte-to-lymphocyte ratio were higher in patients with prostate cancer, but without significance. The mean WBC and leukocyte count were lower in patients with prostate cancer, but again without statistical significance (p=0.130). The mean TPSA and FPSA were 39.4 and 5.67, respectively in patients with prostate cancer, while they were 5.78 and 1.28 in patients with BPH. There was a significant difference in the mean TPSA and FPSA levels between the patient groups (p<0.001). Conclusions: Our study results showed that patients with prostate cancer had a lower level of lymphocytes, neutrophils and WBCs and a higher level of monocytes with a significant difference in lymphocyte count, compared to healthy controls. We suggest that lymphocyte count may be used in combination with other parameters in the diagnosis of prostate cancer, thanks to its ease of assessment.

Malignant tumors are often accompanied by increased risk of hematological abnormalities. However, few studies have reported any prognostic impact of preoperative thrombocytosis, leukocytosis and anemia in epithelia ovarian cancer (EOC). This study aimed to investigate preoperative hematological parameters for anemia, leukocytosis and thombocytosis in relation to established prognostic factors and survival in EOC cases. A total of 816 Chinese women treated for EOC were retrospectively included in the study focusing on the relationship between preoperative hemoglobin, leukocyte and platelet counts, and a panel of clinicopathologic characteristics and outcome. Preoperative anemia was present in 13.4%, leukocytosis in 16.7% and thrombocytosis in 22.8%. Additionally, EOC patients with low differentiation grade, advanced stage, lymph node (LN) metastasis, residual disease ${\geq}1cm$, ascites volume >1,000ml, serum cancer antigen 125 (CA125) >675U/ml, and disease recurrence had the higher prevalence of preoperative anemia, leukocytosis and thrombocytosis (all p<0.05). Moreover, EOC patients with older age or postmenopausal EOC patients had the higher prevalence of thrombocytosis (28.7% vs 17.3% or 26.0% vs 17.7%). Furthermore, in a Cox proportional hazard model, thrombocytosis was an independent factor for progression-free survival (PFS) and overall survival (OS) (p<0.001). Conclusively, preoperative anemia, leukocytosis or thrombocytosis in EOC patients is closely associated with more malignant disease phenotype and poorer prognosis. Significantly, thrombocytosis may independently predict the disease-specific survival for EOC patients.

Objective: To investigate the prognostic role of antigen KI-67 (Ki-67) and G1/S-specific cyclin-D1 (cyclin-D1) in patients with laryngeal squamous cell carcinoma (LSCC). Methods: Immunohistochemical staining (IHS) was used to determine the protein expression of Ki-67 and cyclin-D1 in LSCC tissues. Kaplan-Meier survival curves was calculated with reference to Ki-67 and cyclin-D1 levels. Results: Cyclin-D1 and Ki67 were expressed in the nuclei of cancer cells. Among the total of 92 cancer tissues examined by immunohistochemistry, 60 (65.22%) had cyclin-D1 overexpression and 56 (60.87%) had Ki67 overexpression. Cyclin-D1 overexpression is associated with the advanced stage of the cancer (P=0.029), but not with gender, age, stage of cancer, histological differentiation, anatomical site, smoking history and alcohol consumption history. Ki67 overexpression is not associated with the advanced stage, gender, age, histological differentiation, anatomical site, smoking history and alcohol consumption history. A statistically significant correlation was found between lymph node status and the expression of Ki67 (p = 0.025). Overexpression of cyclin-D1 was correlated to shorter relapse-free survival period (P<0.001). Conclusions: Overexpression of cyclin-D1 can be used as a marker to predict relapse in patients with LSCC after primary curative resection.
