Abstract
BACKGROUND AND PURPOSE Montelukast and S-carbocysteine have been used in asthmatic patients as an anti-inflammatory or mucolytic agent respectively. S-carbocysteine also exhibits anti-inflammatory properties. EXPERIMENTAL APPROACH Ovalbumin (OVA) sensitized BALB/c mice were challenged with OVA for 3 days followed by single OVA re-challenge (secondary challenge) 2 weeks later. Forty-eight hours after secondary challenge, mice were assessed for airway hyperresponsiveness (AHR) and cell composition in bronchoalveolar lavage (BAL) fluid. Suboptimal doses of 10 mg.kg(-1) of S-carbocysteine by intraperitoneal injection (ip), 20 mg.kg(-1) of montelukast by gavage, the combination of S-carbocysteine and montelukast or 3 mg.kg(-1) of dexamethasone as a control were administered from 1 day before the secondary challenge to the last experimental day. Isolated lung cells were cultured with OVA and montelukast to determine the effects on cytokine production. KEY RESULTS Treatment with S-carbocysteine or montelukast reduced both AHR and the numbers of eosinophils in BAL fluid. Neutralizing IFN-gamma abolished the effects of S-carbocysteine on these airway responses. Combination of the two drugs showed further decreases in both AHR and eosinophils in the BAL fluid. Goblet cell metaplasia and Th2-type cytokines, interleukin (IL)-4, IL-5 and IL-13, in BAL fluid were decreased with montelukast treatment. Conversely, S-carbocysteine increased Th1-type cytokines, IFN-gamma and IL-12 in BAL fluid. CONCLUSIONS AND IMPLICATIONS The combination of two agents, montelukast and S-carbocysteine, demonstrated additive effects on AHR and airway inflammation in a secondary allergen model most likely through independent mechanisms of action.

Abstract
BACKGROUND AND STUDY AIMS Narrow band imaging combined with magnifying endoscopy (NBI-ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity. The risk of a second primary SCC of the head and neck is very high in patients with esophageal SCC. This prospective study evaluated the detection rate of superficial SCC within the head and neck region (superficial SCCHN) with NBI-ME in patients with esophageal SCC. PATIENTS AND METHODS Between March 2006 and February 2008, 112 patients with a current or previous diagnosis of esophageal SCC were enrolled. All patients underwent endoscopic screening of the head and neck by NBI-ME. The primary end point was the detection rate for superficial SCCHN. Secondary end points were to compare demographic characteristics between patients with and without superficial SCCHN and to assess the clinical course of patients with superficial SCCHN. RESULTS The detection rate for superficial SCCHN was 13 % (15/112). The prevalence of multiple Lugol-voiding lesions, observed endoscopically throughout the esophageal mucosa after application of Lugol dye solution, was significantly higher in patients with superficial SCCHN than in those without (100 % vs. 24 %, P < 0.0001). Minimally invasive curative treatment with organ preservation was feasible without severe complications in patients with superficial SCCHN after curative treatment of esophageal SCC. CONCLUSIONS In patients with esophageal SCC, NBI-ME is useful for detecting superficial SCCHN, thereby facilitating minimally invasive treatment.

Abstract
Recent studies have demonstrated the contribution of the gamma subunit of the Fc receptor of IgG (FcRgamma) to neuronal death following ischemic injury and Parkinson's disease. We examined the role of FcRgamma in hippocampal pyramidal cell death induced by kainic acid (KA). FcRgamma-deficient mice (FcRgamma-/-) and their FcRgamma+/+ littermates (wild type, B6) received an injection of KA into the dorsal hippocampus. Pyramidal cell death was quantified 24 and 72 h after the injection. The number of survived pyramidal cells was significantly larger in FcRgamma-/- mice than in B6 mice in both the CA1 and CA3. Immunohistochemical and immunofluorescent studies detected FcgammaRIIB protein in parvalbumin neurons, whereas FcgammaRIII and FcgammaRI proteins were detected in microglial cells. No activated microglial cells were detected 24 h after the KA injection in FcRgamma-/- mice, whereas many activated microglial cells were present in B6 mice. The production of nitrotyrosine as well as of the inducible nitric oxide synthase and cyclooxygenase-2 proteins, increased by 16 h after the KA injection in B6 mice. In addition, tissue plasminogen activator and metalloproteinase-2 proteins increased. By contrast, the magnitude of oxidative stress and the increase in protease expression were mild in FcRgamma-/- mice. Co-injection of a neutralizing antibody against FcgammaRll and FcgammaRlll with KA abolished pyramidal cell death and microglial activation. In addition, the neutralizing antibody reduced oxidative stress and expression of proteases. These observations suggested a role for FcgammaRllB in parvalbumin neurons as well as FcRgamma in microglia in pyramidal cell death.

Abstract
A 30-year-old man was admitted to our hospital due to infectious bulla. His chest X-ray and computed tomography (CT) showed bilateral multiple emphysematous bullae and a left bulla with effusion. He underwent partial lung resection including the bulla with video-assisted thoracic surgery. The bacterial diagnosis of the effusion was infection of Aspergillus. Further, Aspergillus was detected inside the wall in pathological diagnosis. Treatment with itraconazole 100 mg a day was started after surgery, and 6 months later the patient is well without recurrence.

Abstract
Chronic lung disease (CLD) affects premature newborns requiring supplemental oxygen and results in impaired lung development and subsequent airway hyperreactivity. We hypothesized that the maintenance of peroxisome proliferator-activated receptor gamma (PPARgamma) signaling is important for normal lung morphogenesis and treatment with PPARgamma agonists could protect against CLD and airway hyperreactivity (AHR) following chronic hyperoxic exposure. This was tested in an established hyperoxic murine model of experimental CLD. Newborn mice and mothers were exposed to room air (RA) or moderate hyperoxia (70% oxygen) for 10 days and fed a standard diet or chow impregnated with the PPARgamma agonist rosiglitazone (ROSI) for the duration of study. Following hyperoxic exposure (HE) animals were returned to RA until postnatal day (P) 13 or P41. The accumulation of ROSI in neonatal and adult tissue was confirmed by mass spectrometry. Analyses of body weight and lung histology were performed on P13 and P41 to localize and quantitate PPARgamma expression, determine alveolar and microvessel density, proliferation and alpha-smooth muscle actin (alpha-SMA) levels as a measure of myofibroblast differentiation. Microarray analyses were conducted on P13 to examine transcriptional changes in whole lung. Pulmonary function and airway responsiveness were analyzed at P55. ROSI treatment during HE preserved septation and vascular density. Key array results revealed ontogeny groups differentially affected by hyperoxia including cell cycle, angiogenesis, matrix, and muscle differentiation/contraction. These results were further confirmed by histological evaluation of myofibroblast and collagen accumulation. Late AHR to methacholine was present in mice following HE and attenuated with ROSI treatment. These findings suggest that rosiglitazone maintains downstream PPARgamma effects and may be beneficial in the prevention of severe CLD with AHR.

Abstract
3037 Background: Pancreatic cancer has a poor prognosis. Tumor-specific cytotoxic T lymphocytes (CTLs) can be activated in vivo by dendritic cell (DC)-based vaccination. However, clinical responses to the immunotherapy with DC vaccination have only been observed in a minority of patients with solid cancer. Combination with other treatment modalities such as chemotherapy may overcome immunoresistance of cancer cells. It has been shown previously that gemcitabine as well as S-1 sensitises human pancreatic carcinoma cells against CTL-mediated lysis. In the current study, the clinical efficacy of the DC vaccine pulsed with the peptide derived from pancreatic cancer-associated antigen in combination with gemcitabine/S-1 has been evaluated in the patients with advanced, inoperable pancreatic cancer. Methods: Thirteen patients with advanced, inoperable pancreatic cancer refractory to standard treatment were entered the study. DCs that were generated from CD14+ monocytes from leukapheresis by 6-day cultivation with granulocyte macrophage-colony stimulating factor (GM-CSF) and interleukin (IL)-4 were matured by OK-432, a streptococcal agent, and were pulsed with the pancreatic cancer-associated antigen. These DCs (1 x 107) were intradermally administered 5 times at 14-day intervals concomitantly combined with gemcitabine and/or S-1. Results: Of the 13 patients, complete response (CR) was observed in 2 (15.4%), partial response (PR) in 7 (54.8%), stable disease (SD) in 2 (15.4%), progressive disease (PD) in 2 (15.4%). Response rate was 69.2%. Survival rate, quality of life, and performance status were markedly increased. Severe side effects of more than grade 3 that were assessed in accordance with NCI-Common Toxicity Criteria v.2.0, were not observed. Conclusions: It was strongly suggested that the DC vaccination pulsed with cancer associated-peptid in combination with gemcitabine and/or S-1 was safety and effective in the patients with the inoperable pancreatic cancer refractory to standard treatment. No significant financial relationships to disclose.

Abstract
Epithelioid cells are found in lymph nodes in cases of metastatic carcinoma; however, epithelioid cells with benign features have also been discovered incidentally in lymph nodes. Epithelioid cells were observed in mediastinal lymph nodes of cattle without cancer during routine diagnostic necropsy. To explain this finding, the authors evaluated the prevalence and histopathologic, immunohistochemical, and ultrastructural features retrospectively using mediastinal lymph nodes from 110 cattle and found that 66 of the lymph nodes contained epithelioid cells. In all 66 nodes, most of the epithelioid cells were individual or aggregated in nodal sinuses; in 21 nodes, some epithelioid cells formed tubular structures. The individual and aggregated epithelioid cells were mostly considered to be mesothelial in origin by immunohistochemical and ultrastructural examination; presumably, they entered the lymph nodes via lymphatic vessels, because they were found in afferent lymphatic vessels and nodal sinuses. Although the presence of epithelioid cells in lymph nodes prompts suspicion of metastatic carcinoma, the epithelioid cells in these bovine lymph nodes did not disrupt nodal architecture, lacked atypia or mitotic figures, and did not invade nodal parenchyma.

Abstract
UNLABELLED Even with substantial progress in the management of patients with glycogen storage disease type Ia (GSD-Ia), hepatic and renal complications may still develop during long-term follow-up. Herein, we report a case of preemptive living donor liver transplantation in a patient with GSD-Ia. PATIENT The patient was a 5-year-old boy in whom GSD-Ia was diagnosed at age 10 months. Clinical symptoms included frequent hypoglycemic episodes, hyperlipidemia, hyperuricemia, and growth retardation, which were poorly controlled using conventional treatments. At age 5 years, frequent massive nasal bleeds developed, which led to severe anemia. The patient was brought to our institute for living donor liver transplantation (LDLT). Because GSD-Ia usually responds to dietary and medical treatments, we had a long discussion to determine whether preemptive LDLT was indicated. Transplantation was performed using the left lateral liver segment from the patients mother. The weight of his native liver was almost 2 kg. After reperfusion of the graft, the blood glucose concentration rapidly increased, and regular glucose was administered throughout the operation. The posttransplantation course was uneventful. The patient had no episodes of hypoglycemia with a regular diet. Total cholesterol, triglyceride, and uric acid concentrations also reverted to normal without medication. The patient had a few episodes of nasal bleeding after transplantation, which stopped spontaneously. He was discharged from our hospital with normal liver function. CONCLUSION Patients with GSD-Ia should be considered for preemptive LDLT to improve their quality of life when clinical symptoms do not respond to appropriate treatment.

Abstract
BACKGROUND We carried out immunohistochemistry to examine the expression of nm23-H1 in Hodgkin and Reed-Sternberg cells in patients with classical Hodgkin's lymphoma (CHL). PATIENTS AND METHODS We evaluated 128 patients with CHL [87 patients with nodular sclerosis (NS) and 41 patients with mixed cellularity (MC)] for CD15, CD20, Ki-67, EBER, TIA-1, and nm23-H1 by immunohistochemistry. RESULTS CD15 was expressed in 79%, CD20 in 11%, Ki-67 in 93%, EBER in 34%, TIA-1 in 11%, and nm23-H1 in 60% of the CHL patients. NS patients showed a significantly higher rate of nm23-H1 expression than MC patients (P < 0.001). The serum nm23-H1 level was significantly higher in patients with positive nm23 expression. Univariate analysis showed that stage IV, poor performance status, low hemoglobin level, low serum albumin level, age of 45 years or older, TIA-1-positive status, and nm23-H1-positive status were associated with significantly shorter progression-free survival. Multivariate analysis with these factors showed TIA-1 and cytoplasmic nm23-H1 expression to be significant and independent prognostic factors. CONCLUSIONS Our results indicate that nm23-H1 expression is a prognostic factor for CHL and that it is as important as serum nm23-H1, both of which are useful for planning the treatment strategy.

Abstract
AIMS/HYPOTHESIS A decrease in plasma adiponectin levels has been shown to contribute to the development of diabetes. However, it remains uncertain whether adiponectin plays a role in the regulation of insulin secretion. In this study, we investigated whether adiponectin may be involved in the regulation of insulin secretion in vivo and in vitro. METHODS The effect of adiponectin on insulin secretion was measured in vitro and in vivo, along with the effects of adiponectin on ATP generation, membrane potentials, Ca2+ currents, cytosolic calcium concentration and state of 5'-AMP-activated protein kinase (AMPK). In addition, insulin granule transport was measured by membrane capacitance and total internal reflection fluorescence (TIRF) analysis. RESULTS Adiponectin significantly stimulated insulin secretion from pancreatic islets to approximately 2.3-fold the baseline value in the presence of a glucose concentration of 5.6 mmol/l. Although adiponectin had no effect on ATP generation, membrane potentials, Ca2+ currents, cytosolic calcium concentrations or activation status of AMPK, it caused a significant increase of membrane capacitance to approximately 2.3-fold the baseline value. TIRF analysis revealed that adiponectin induced a significant increase in the number of fusion events in mouse pancreatic beta cells under 5.6 mmol/l glucose loading, without affecting the status of previously docked granules. Moreover, intravenous injection of adiponectin significantly increased insulin secretion to approximately 1.6-fold of baseline in C57BL/6 mice. CONCLUSIONS/INTERPRETATION The above results indicate that adiponectin induces insulin secretion in vitro and in vivo.

Abstract
Endoscopic submucosal dissection (ESD) has become a widely accepted method for treating gastrointestinal cancer. The aim of this study was to evaluate the efficacy and safety of ESD for gastric cancer in patients with liver cirrhosis. A total of 18 gastric cancers were treated by ESD in 15 patients with cirrhosis. The rate of en bloc resection was 88.9% (16/18). En bloc resection with tumor-free lateral/basal margins (R0 resection) was 77.8% (14/18). Three patients had postoperative bleeding and underwent emergency gastroscopy for hemostasis. No recurrence was observed during the median follow-up of 21.4 months, excluding three patients in whom additional endoscopic resection or surgery was carried out. ESD can be safely performed for gastric cancer in patients with cirrhosis, resulting in a high en bloc resection rate.

Abstract
Sivelestat sodium hydrate is a selective inhibitor of neutrophil elastase (NE), and is effective in acute lung injury associated with systemic inflammatory response syndrome (SIRS). The effect of Sivelestat for postoperative clinical courses after transthoracic esophagectomy was investigated. Consecutive patients with carcinoma of the thoracic esophagus who underwent transthoracic esophagectomy between 2003 and 2004 were assigned to the Sivelestat-treated group (n = 18), and those between 1998 and 2003 were assigned to the control group (n = 25). The morbidity rate, duration of postoperative SIRS, mechanical ventilation, and intensive care unit (ICU) stay, and the sum of the sequential organ failure assessment scores at all time points after the operation were compared. Serum NE activities and serum concentrations of TNF-alpha, IL-1beta, IL-6, and high mobility group box chromosomal protein 1 (HMGB1) were measured. Postoperative complications developed in three patients in the control group, and one in the Sivelestat-treated group. The durations of SIRS, mechanical ventilation, and ICU stay were significantly shorter in the Sivelestat-treated group. Even in patients without complications, the durations of mechanical ventilation, and ICU stay were also significantly shorter, and the arterial oxygen pressure/fraction of inspired oxygen ratio at postoperative day 1 was significantly higher in the Sivelestat-treated group. Serum NE activities and serum concentrations of IL-1beta, IL-6, and HMGB1 were significantly suppressed in the Sivelestat-treated group. Postoperative Sivelestat treatment after transthoracic esophagectomy improves the condition of SIRS and postoperative clinical courses, even in patients without complications.

Abstract
Interleukin (IL)-18 production and pulmonary function were evaluated in patients with chronic obstructive pulmonary disease (COPD) in order to determine the role of IL-18 in COPD. Immunohistochemical techniques were used to examine IL-18 production in the lungs of patients with very severe COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage IV, n = 16), smokers (n = 27) and nonsmokers (n = 23). Serum cytokine levels and pulmonary function were analysed in patients with GOLD stage I-IV COPD (n = 62), smokers (n = 34) and nonsmokers (n = 47). Persistent and severe small airway inflammation was observed in the lungs of ex-smokers with very severe COPD. IL-18 proteins were strongly expressed in alveolar macrophages, CD8+ T-cells, and both the bronchiolar and alveolar epithelia in the lungs of COPD patients. Serum levels of IL-18 in COPD patients and smokers were significantly higher than those in nonsmokers. Moreover, serum levels of IL-18 in patients with GOLD stage III and IV COPD were significantly higher than in smokers and nonsmokers. There was a significant negative correlation between serum IL-18 level and the predicted forced expiratory volume in one second in patients with COPD. In contrast, serum levels of IL-4, IL-13 and interferon-gamma were not significantly increased in any of the three groups. In conclusion, overproduction of interleukin-18 in the lungs may be involved in the pathogenesis of chronic obstructive pulmonary disease.

Abstract
In the present study, 15 canine ovaries without morphological lesions were examined histologically and immunohistochemically by using a large number of proteins including AE1/AE3, cytokeratin7 (CK7), CK13, CK20, vimentin, desmin, alpha smooth muscle actin (alphaSMA), calponin, S100, Neurofilaments, Inhibinalpha, placental alkaline phosphatase (PLAP) and neuron-specific enolase. Ovarian structures observed in this study included surface epithelium (SE), cortical tubules (CT), tunica albuginea (TA), stromal cells (SC), internal endocrine cells (IE), rete ovarii (RO) and fallopian tubes (FT). SE, CT, RO and FT were broadly immunoreactive for desmin. Besides AE1/AE3 and vimentin, desmin was also closely linked to these structures. Rete ovarii forming a reticular structure showed a positive reaction to S100. Surface epithelium was immunoreactive for PLAP at a significantly high level. In conclusion, these results indicate a specific segment of immunoreactivity as well as the broad range of immunoreactivity in canine ovary. The distinct patterns of immunoreactive for various kinds of proteins will play an important role in facilitating their identification and discrimination even in a normal canine ovary with a complex structure.
