Purpose: B cell-activating factor (BAFF) is a tumor-necrosis factor (TNF) superfamily member best known for its role in the survival and maturation of B cells. BAFF activity is observed in naive cells as well as in effector/memory T cells. We aimed to explore whether BAFF in sputum is expressed at elevated levels in asthmatic airways and associated with eosinophilic inflammation, pulmonary function, and bronchial hyperresponsiveness in children. Methods: One hundred and fifty-four asthmatic children and 98 healthy children were enrolled in the study. Sputum supernatants were collected and sputum BAFF and eosinophil cationic protein (ECP) levels were measured. We performed pulmonary function tests and methacholine challenge tests, while measuring total eosinophil count, total serum IgE, and serum ECP in all subjects. Results: Asthmatic children had significantly higher levels of BAFF in induced sputum [26.50 (10.50-100.27) pg/mL] compared to healthy children [18.32 (7.68-44.63) pg/mL; $P$=0.011]. Sputum BAFF positively correlated with sputum eosinophils (${\gamma}$=0.406, $P$<0.001) and sputum ECP (${\gamma}$=0.789, $P$<0.001). Significant negative correlations were found between sputum BAFF and FEV1 (${\gamma}$=-0.291, $P$<0.001) or post-bronchodilator FEV1 (${\gamma}$=-0.334, $P$<0.001), whereas nonsignificant correlations were found between sputum BAFF and bronchial hyperresponsiveness, serum eosinophil count, and serum ECP. Conclusion: These findings suggest that BAFF may play a role in childhood asthma, and BAFF levels in sputum could be a supportive marker that represents airway inflammation, especially eosinophilic inflammation.

This research aimed to investigate the time-course effect of epichlorohydrin (ECH) on epididymal histopathology in Sprague-Dawley rats. Twenty-four male rats were randomly assigned to four groups with 6 rats in each group and were administered a single oral dose of ECH (70 mg/kg) or its vehicle. Six animals each were sacrificed on days 0 (control), 1, 2, and 7 after treatment. During the study period, clinical signs, body weights, reproductive organ weights, testicular spermatid count, epididymal sperm count, motility and morphology, and histopathology were examined. No treatmentrelated effects on body weights and reproductive organ weights were noted at any time point. On the contrary, sperm motility decreased slightly on days 1 and 2 after treatment and then decreased significantly on day 7 after treatment. The first signs of histological changes were the appearance of cell debris in the ducts and vacuolization of the epithelial cells observed in the proximal caput epididymis on day 1 after treatment. The incidences and grades of the histological changes including cell debris in the ducts, epithelial vacuolization, oligospermia, and epithelial disruption increased on day 2 and then decreased slightly on day 7 after treatment. These results show that a single oral dose of 70 mg/kg ECH to male rats results in cell debris in the ducts and vacuolization of the epithelial cells in the proximal caput epididymis, followed by reversible oligospermia, epithelial disruption, and decreased sperm motility.

Soy yogurt beverage (SYB) was prepared from defatted soybean flour and flavor, effect of stabilizers on sedimentation and change of acidity and cell concentration during storage of SYB were investigated. The flavor of SYB rated significantly different and slightly inferior to milk yogurt although flavors added to SYB improved the acceptability. The curd in SYB precipitated greatly during the first 24 hours of storage. The sedimentation of curd was reduced by the addition of CMC of 0.4% or PGA of 0.1%. SYB can be kept at $5^{\circ}C$ for 48 days without significant change in viable cell count of lactic acid bacteria. pH, titratable acidity and viable cell count of SYB was significantly changed for 48 days at $25^{\circ}C$. Some of SYB samples were contaminated by yeast and mold.

In order to study the effect of direct moxibustion on depressed immune response and thyroid hormone in rats exposed to cold stress, Sprague-Dawley male rats were put in the horizontal refrigerator by $-10^{\circ}C$ for 14 days and thereafter $-18^{\circ}C$ for 11 days(control group). Sample I group was treated by daily direct moxibustion to bilateral Shinsu(BL23) from the 22nd day to the 25th day for 4 days under the same condition with the control group. Sample II group was treated by daily direct moxibustion to bilateral non-acupoints near the root of the tail from the 22nd day to the 25th day for 4 days under the same condition with the control group. And RBC, WBC, CD4+ T cell count, T3, T4 and TSH were measured. The results were as follows; 1. RBC increased with statistical significance in the sample I and sample II groups compared with the control group. 2. WBC increased with statistical significance in the sample I group, but there was not any significance in the sample II group compared with the control group. 3. Lymphocyte increased with statistical significance both in the sample I and sample II groups compared with the control group. 4. CD4+ T cell count increased with statistical significance both in the sample I and sample II groups compared with the control group. 5. T3, T4 and TSH increased respectively with statistical significance in the sample I and sample II groups compared with the control group.

Background: Hyaluronan (HA) is an unbranched glycosaminoglycan. It has been proposed that HA acts as a vehicle for cytokines due to the strong negative charge on its surface. We hypothesized that HA would function like a cytokine scavenger and reduce the inflammatory signaling cascade and this would lead to improved survival in rats suffering with endotoxemia. Methods: Endotoxin (Salmonella, 10 mg/kg) or an equal amount of 0.9% NaCl (NS) was injected into the jugular vein of rats. HA (1,600 kDa, 0.35%) or NS was given at 0.1 mL/kg/h for 3 hours. HA or NS infusion was started at 4 hour after endotoxin injection. The rats were divided into the control and HA groups (n=16 for each group). The mean arterial pressure (MAP) was monitored during HA or normal saline infusion. Survival was assessed every 12 hours for 3 days throughout the experiment. Results: The survival rate (%) of the rats treated with HA was higher (60%) than that of the controls (20%) when HA was infused 4 hours after lipopolysaccharide (LPS) injection. The bronchoalveolar lavage (BAL) fluid of the animals surviving HA or NS infusion 4 hours after LPS showed that the total cell counts and number of neutrophils were significantly (p < 0.01) reduced in the HA treated groups compared with that of the controls (total cell count, $9.2{\times}10^4$/mL vs. $61{\times}10^4$/mL; neutrophils, $21{\times}10^4$/mL vs. $0.2{\times}10^4$/mL, respectively). There was no significant MAP difference between the HA or control groups either with or without endotoxin. Conclusion: Infusion of hyaluronan (1,600 kDa) reduced the BAL total cell count and the number of neutrophils and it improved the survival rate of the endotoxemic rats.

The plant Ichnocarpus frutescens (Linn) R.Br. (Family-Apocynaceae) has been indicated for the treatment of various diseases, one amongst it is cancer. The purpose of this study was to investigate experimentally the possible antitumor activity and antioxidant role of Ichnocarpus frutescens in the mice transplanted with Ehrlich ascites carcinoma (EAC). The chloroform and methanol extract of whole plant of Ichnocarpus frutescens (CEIF and MEIF) were administered intraperitoneally at the dose of 150 mg/kg and 300 mg/kg, body weight per day for 7 days after 24 h of tumor inoculation in mice. Treatment with CEIF at the dose of 150 mg/kg and 300 mg/kg remarkably decreased the tumor volume, packed cell volume, viable cell count and increased the nonviable cell count of EAC tumor bearing mice when compared to e effect of MEIF at 150 mg/kg and 300 mg/kg. Further the EAC mice treated with CEIF and MEIF showed significant decrease in the level of lipid peroxidation and significant increase in the level of antioxidant enzymes such as glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT), however the decreasing and increasing capacity of CEIF was less in both doses as compared to MEIF. Based on these results, it can be concluded that the chloroform and methanol extact of Ichnocarpus frutescens exhibit significant antitumor and antioxidant activity in EAC bearing mice.

Background: Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases. Materials and Methods: A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011-2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups. Results: No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (p>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (p<0.05). Conclusions: No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

Background: Chronic lymphoid leukemia (CLL) is the most frequent type of adult leukemia. The Rai and Binet staging systems have been well recognized as standards for assessing the treatment requirements and overall survival in CLL patients. However, there is a need to seek newer prognostic markers to identify stable or progressive forms of CLL that will facilitate risk-adapted treatment strategies. Currently a molecular biomarker ZAP-70 has attracted interest as providing prognostic information in CLL patients. Objective: To determine the frequency of ZAP-70 positivity in B-CLL patients at disease presentation. Materials and Methods: From January 2011 to September 2014, 89 patients were diagnosed to have chronic lymphoid leukemia. Complete blood count was done on an automated analyzer (Cell Dyne, Abott Architect, USA), while immunophenotyping was conducted for each patient to establish the diagnosis of the disease. ZAP-70 expression was evaluated by flow cytometry. Data were compiled and analyzed by SPSS version 21. Results: Out of the total of 89 B-CLL patients, 62 (69.7%) were male and 27 (30.3%) were females with a male to female ratio of 2:1. The mean age was $57.5{\pm}12.1years$. The frequency of ZAP-70 positivity in our B-CLL patients was found to be 13.5%. ZAP-70 positivity was significantly correlated with stage III disease and high absolute lymphocytic count (P<0.05). No correlation of ZAP-70 could be established with age and gender (p>0.05). Conclusions: The frequency of ZAP-70 in our patients appears low. It is approximately half that in international data. We would recommend to screen all the newly diagnosed patients with CLL for ZAP-70 protein expression for risk stratification, family counseling and to predict overall survival.

Background: In our study, the LDH, albumin, hemoglobin, neutrophile, thrombocyte, lymphocyte counts and prognostic significance of neutrophile-lymphocyte and thrombocyte-lymphocyte ratios in NSCLC derived from these counts obtained during regular examinations of patients were examined. Materials and Methods: Histopathologically diagnosed non-small-cell-lung cancer patients between 2008 and 2010 were included in the study. Before the treatment, full blood count including routine lymphocyte count, blood biochemistry examinations including liver (AST, ALT, total protein, Albumin), LDH and kidney (BUN, Cre) function tests were performed. Results: A total of 156 patients, 76 of whom (48.7%) were female and 80 of whom (51.3%) were male were included. Mean hemoglobin level was determined as 12. Overall survival was found to be significantly dependent on whether patients were anemic or not (p: 0.005). Mean LDH level was determined as 233.4. There was nosurvival difference between patients with and without high LDH (p: 0.532). In patients where NLR showed systemic inflammatory response, overall survival was 10.8 months whereas this duration was 19.6 months in patients where the systemic inflammatory response was negative (p: 0.012). In patients where TLR showed systemic inflammatory response, overall survival was 13.6 months whereas this duration was 21.9 months in patients where the systemic inflammatory response was negative (p: 0.04). Conclusions: Molecular methods have been changing rapidly in today's world and they manage the treatment besides defining the prognosis of patients. However, easily accessible and cheap laboratory parameters should be considered in the prognosis of patients besides these new methods.

A total of 466 foremilk from dairy farms in Chonnam district was examined for the subclinical mastitis over a period of one year, using a method of the electrical conductivities(EC); absolute conductivity(AC) and differential conductivity(DC) and quarter difference value(QD), in relation to the California mastitis test(CMT) and the direct somatic cell count(DSCC). The compatibility and efficiency rating between the EC values and the other screening tests was conducted. Obtained results are summarized as follows. 1. A linear relationship was found between the EC values and the CMT scores and direct somatic cell counts and it was found that electrical conductivity measurements were comparable with other screening tests for diagnosing animals with mastitis. 2. Compatibilities between the EC and CMT were 70.4% in AC, 74.6% in DC and 70.7% in QD, and that of the EC and DSCC were 53.0% in AC, 63.1% in DC and 53.2% in QD. On the other hand, relative efficiency ratings of Postle's equation between EC and CMT were 37.3% in AC, 26.5% in DC and 13.6% in QD, and that of the EC and DSCC were 33.1% in AC, 20.2% in DC and 11.9% in QD. 3. In the foremilk samples collected from damaged quarters determined by EC, the false positive rate wart higher than the false negative rate, and consequently tests of EC produced lower compatibility or efficiency rating scores. These tendencies suggested that any factors other than the mastitic condition influencing the EC values might be existed.
