  • The physiological responses following stress are different in individual or personality. We performed this study to clarify gender differences in influences of noise stress on physiological factors. 70 healthy subjects, which was divided man (n=30) and woman (n=40) groups, were exposed to 85 decibels of excavator noise for 15 minutes. Cardiac factors such as heart rate (HR), systolic and diastolic blood pressures (SBP and DBP, respectively), and heart rate-systolic pressure product (RPP) were determined. Transcranial Doppler ultrasound (TCD) was used to measure mean blood flow velocity (Vm), pulsatility index (PI), and resistance index (RI) in the middle, anterior and posterior cerebral arteries (MCA, ACA and PCA, respectively) before and during noise exposure. Cortisol level and hematological variables were also measured before (baseline) and immediately after the end of noise exposure. In the both groups HR, SBP, and RPP significantly decreased during noise exposure (P<0.05) but not significantly different between two groups (P>0.05). Vms of three cerebral arteries in man group decreased, whereas Vm of PCA in woman group fell during noise exposure (P<0.05). Vm, PI and RI in MCA and ACA during noise exposure were low in man group compared with woman group (P<0.05). Vm of PCA was low, whereas PI and RI of PCA were high in man group compared with woman group during noise exposure (P<0.05). Total leukocyte and red blood cell (RBC) counts slightly decreased during noise exposure but not significant (P>0.05). Levels in hematological variables decreased but not significant changed following noise exposure. Decreased rate of total leukocyte in man group was higher (P<0.05). Cortisol levels in the both groups decreased immediately after the end of noise exposure, while the decreased rate in man group was greater than that in woman group (p<0.05). These findings indicate that a transient exposure to experimental excavator noise may cause decreased changes in cardiac factors, cerebral hemodynamics and cortisol levels and the changes may be greater in men than in women.

  • Background: The standard treatment in the metastatic colorectal cancer consists of 5-FU based infusional regimens. However, with oral fluoropyrimidines, equal tumor responses may be obtained. Capecitabine causes macrocytosis of the cells by inhibition of DNA synthesis. In this context, a relationship was found between mean corpuscular volume (MCV) and response to therapy in breast cancer patients treated with Capecitabine, but whether this relationship also pertains in colorectal cancer has not been established. Materials and Methods: A total of 102 metastatic colorectal cancer patients treated with a oxaliplatin (XELOX)${\pm}$Bevacizumab combination were retrospectively evaluated. Patients were randomized into three groups. Hematological parameters (MCV, MPV, PCT, PLT, NLR) were recorded retrospectively, before treatment and after 3 cycles of chemotherapy. Results: After three cycles of therapy, 20 (19.6%) patients had progressive disease (PD), 41 (40.1%) had stable disease (SD), and 41 (40.1%) demonstrated a partial response (PR). In 62 (60.7%) treatment was with capesitabin plus XELOX therapy, and in 40 (39.2%) it was XELOX-Bevacizumab combination therapy. There was no difference among three groups before the treatment in terms of MCV, MPV, PCT, PLT, and NLR. MCV showed significant increase in chemotherapy response groups (PR and SD). In addition, a significant decrease was observed for platelet count in chemotherapy response groups. While NLR decrease was seen in only a PR group, PCT decrease was observed in all three groups. PCT and PLT values were higher in patients receiving Bevacizumab. Conclusions: PLT, PCT, MPV, and NLR values were decreased due to Capecitabine-based chemotherapy, however MCV was increased. PCT and PLT values were higher in patients who received Bevacizumab than those who did not. MCV, PLT, and NLR can be considered as important factors in predicting response to colorectal carcinoma treatment.

  • This study was conducted to replace fish meal (FM) with three plant proteins (soybean meal, soy protein concentrate, and wheat gluten) in diets for growing olive flounder Paralichthys olivaceus. The control diet was formulated to contain 65% sardine FM and four other replacement diets were formulated to replace FM with the plant proteins by 25, 30, 35 and 40% (designated FM25, FM30, FM35 and FM40, respectively). The replacement diets were added with three essential amino acids (lysine, methionine and threonine) to meet their requirements for the fish. Olive flounder (initial average weight, 96.8±0.2 g) were randomly distributed into 20 tanks (425 L each) at a density of 25 fish per tank. Four replicate groups of fish were fed one of the diets two times daily for 15 weeks. At the end of the feeding trial, no significant differences were found among all the fish groups in growth performance, feed utilization, nonspecific immune responses and hematological health parameters. Thus, this result indicates that the plant proteins with the three limiting amino acids could replace FM up to 40% in diets for growing olive flounder.

  • Methoxy polyethylene glycol-epoetin beta (MPG-EPO), a continuous erythropoietin receptor activator, is a new erythropoiesis-stimulating agent with a long half-life. The purpose of this prospective study is to assess the effects of once-monthly subcutaneous MPG-EPO on hematological responses and nutritional status in peritoneal dialysis patients. Forty four patients undergoing stable peritoneal dialysis were enrolled into the study. Darbepoetin alfa therapy, in peritoneal dialysis patients, was converted to the monthly administration of subcutaneous MPG-EPO for 6 months. The starting dose of MPG-EPO was based on the previous weekly dose of darbepoetin alfa. The dose adjustments were performed to maintain the hemoglobin (Hb) levels in a target range of 10.5-11.0 g/dL. If the Hb levels exceeded 11.0 g/dL, MPG-EPO was temporarily interrupted for 1 month. The mean Hb levels were stable with the values of $9.5{\pm}1.1$ g/dL at baseline, and $10.4{\pm}0.9$ g/dL at the 6th month after conversion. The mean differences in the changes of Hb levels between the baseline and the 6th month were $0.9{\pm}1.4$ g/dL, which was statistically significant. However, the mean differences of iron, transferrin saturation and ferritin concentrations were not significant. It did not show significant differences in the changes of the nutritional parameters. These results suggest that the once-monthly subcutaneous administration of MPG-EPO for 6 months effectively maintains the Hb levels and nutritional status in peritoneal dialysis patients. Taken together, the once-monthly subcutaneous administration of MPG-EPO was practical and might improve the clinical compliance for the management of renal anemia in peritoneal dialysis patients.

  • This study was performed to determine the subacute toxicities of SKI306X, an antiinflammatory herbal extract, in rats. SKI306X was administered orally to rats once a day for 4 weeks at doses of 0.3, 1.0, and 3.0 g/kg/ day. Each group consisted of 20 male and 20 female rats, including 5 male and 5 female rats per group for an interim study at the end of 2-week administration and for a 2-week recovery study, respectively. Throughout the study, all rats survived and no adverse clinical signs were observed. Although male rats treated with high dose (3.0 g/kg/day) of SKI306X showed slight loss of body weight (approximately 5%) in comparison with control animals during the administration period, their body weight loss was normally restored during the recovery period. No significant change was found in all hematological parameters of SKI306X-treated groups except for the decreased number of red blood cells in all female groups at the interim study. Statistically significant changes were observed in several blood enzyme levels of SKI306X-treated groups; however, most of these significant changes were within normal range and statistically significant values did not show dose-related responses. In SKI306X-treated groups, the absolute and relative weights of liver, heart, and stomach were statistically different from those of control group, but these differences disappeared at the end of recovery period and also drug-related gross and histopathological findings in these organs were not found. No other drug-related gross and histopathological findings were observed. It is concluded from the results of this study that non-toxic dose of SKI306X was estimated to be between 0.3 and 1.0 g/kg/day and the maximum tolerated dose of SKI306X was assumed to be higher than 3.0 g/kg/day.

  • This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chicks, reared in metabolism cages until 21 days of age, were distributed in a completely randomized design, with five treatments (0%, 1%, 2%, 3%, and 4% of propolis residue) and six replications. The relative weight of thymus and monocyte percentage were affected by propolis residue, with a quadratic response (p<0.05) and lowest values estimated at 2.38% and 2.49%, respectively. Changes in relative weight of cloacal bursa and spleen, percentage of lymphocyte, heterophil, basophil, eosinophil, and heterophil:lymphocyte ratio, antibody production against Newcastle disease, phagocytic activity of macrophages and the average number of phagocytosed erythrocytes were not observed. The nitric oxide production with regard to positive control (macrophages+erythrocytes) decreased linearly (p<0.05) with increased doses of propolis residue. The remaining variables of nitric oxide production (negative control - macrophages, and difference between the controls) were not affected by propolis residue. The cutaneous basophil hypersensitivity response to phytohemagglutinin as determined by the increase in interdigital skin thickness exhibited a quadratic response (p<0.05), which predicted a lower reaction response at a dose of 2.60% of propolis residue and highest reaction response after 43.05 hours of phytohemagglutinin injection. The inclusion of 1% to 4% of propolis extraction residue in broiler diets from 1 to 21 days of age was not able to improve the immune parameters, despite the modest changes in the relative weight in thymus, blood monocyte percentage, nitric oxide concentration, and interdigital reaction to phytohemagglutinin.

  • Objective: To investigate the clinical effects of whole brain radiotherapy concomitant with targeted therapy for brain metastasis in non-small cell lung cancer (NSCLC) patients with chemotherapy failure. Materials and Methods: Of the 157 NSCLC patients with chemotherapy failure followed by brain metastasis admitted in our hospital from January 2009 to August 2012, the combination group (65 cases) were treated with EGFR-TKI combined with whole brain radiotherapy while the radiotherapy group (92 cases) were given whole brain radiotherapy only. Short-term effects were evaluated based on the increased MRI in brain 1 month after whole brain radiotherapy. Intracranial hypertension responses, hematological toxicity reactions and clinical effects of both groups were observed. Results: There were more adverse reactions in the combination group than in radiotherapy group, but no significant differences were observed between the two groups in response rate (RR) and disease control rate (DCR) (P>0.05). Medium progression free survival (PFS), medium overall survival (OS) and 1-year survival rate in combination group were 6.0 months, 10.6 months and 42.3%, while in the radiotherapy group they were 3.4 months, 7.7 months and 28.0%, respectively, which indicated that there were significant differences in PFS and OS between the two groups (P<0.05). Additionally, RPA grading of each factor in the combination group was a risk factor closely related with survival, with medium PFS in EGFR and KRAS mutation patients being 8.2 months and 11.2 months, and OS being 3.6 months and 6.3 months, respectively. Conclusions: Whole brain radiotherapy concomitant with target therapy is favorable for adverse reaction tolerance and clinical effects, being superior in treating brain metastasis in NSCLC patients with chemotherapy failure and thus deserves to be widely applied in the clinic.

  • The objective of this study was to examine the effect of dietary supplementation of taurine for juvenile olive flounder (Paralichthys olivaceus) at low water temperature ($16.4{\pm}0.36^{\circ}C$). Fish meal (FM)-based diet was used as the control diet. Four other experimental diets were prepared by adding taurine to FM-based diet at 0.25, 0.50, 1.00, and 1. 50% (T1, T2, T3, and T4, respectively). Each experimental diet was fed to triplicate groups of fish (initial mean body weight, 19.5 g) for 10 weeks. At the end of the feeding trial, growth performance and feed utilization, hematological parameters, non-specific immune responses, whole-body proximate composition, and liver mRNA expression of insulin-like growth factor-1 (IGF-1) were investigated. Feed conversion ratio was significantly reduced while protein efficiency ratio was significantly increased in taurine-supplemented groups. Hematocrit and hemoglobin were also significantly increased while plasma cholesterol levels were decreased in taurine-supplemented groups than those in the control group. Nitroblue-tetrazolium, myeloperoxidase and lysozyme activities, and plasma immunoglobulin level were significantly increased by taurine supplementation. These results suggest that dietary taurine supplementation is effective in improving growth performances, feed utilization, and innate immunity of olive flounder in low water temperature season.
