Abstract
BACKGROUND Mizoribine (MZR) at 3 mg/kg/d shows less potent immunosuppressive effects, but high-dose MZR (6 mg/kg/d) was effective and safe in a 2-year study in conjunction with a regimen of cyclosporine (CsA), basiliximab, and corticosteroids. METHODS We compared 40 living-related kidney recipients administered MZR (6 mg/kg/d), CsA (7 mg/kg/d), prednisolone (maintenance dose 10 mg/d), and basiliximab (20 mg/body) with control group (n = 38) treated with CsA, mycophenolate mofetil (MMF; 25 mg/kg/d), basiliximab, and corticosteroids. RESULTS The 4-year graft survival rates for the MZR vs MMF groups were 92.5% vs 94.7%, respectively, with serum creatinine levels of 1.66 ± 1.0 mg/dL vs 1.41 ± 0.42 mg/dL at 3 years, and 1.72 ± 1.16 mg/dL vs 1.56 ± 1.26 mg/dL at 4 years. There was no significant difference in serum creatinine levels between the 2 groups. The MZR group demonstrated a significantly higher rate of elevated serum uric acid values (29.7%). The numbers of patients treated with allopurinol at 4 years were 11/37 (29.7%) for MZR vs 2/36 (5.6%) for the MMF subjects (P < .05). Mean serum uric acid levels of the MZR vs MMF group at 4 years were 7.1 ± 1.9 mg/dL vs 7.0 ± 1.6 mg/dL, respectively (NS). There was no significant difference between the 2 groups regarding bone marrow suppression or liver dysfunction. Severe cytomegalovirus infection was not observed at 3 and 4 years in either group. There were no severe gastrointestinal symptoms among the MZR or the MMF group at 3 or 4 years. CONCLUSIONS The combination of high-dose MZR with CsA, basiliximab, and corticosteroids displayed excellent results over a 4-year follow-up.

Abstract
A 43-year-old Tibetan woman living in northwest Sichuan, China, confirmed to be a taeniasis carrier of Taenia solium was treated with pumpkin seeds combined with Areca nut extract in October 2009. All 20 tapeworms except one without scolex were expelled under good conditions. She was free of secondary cysticercosis within one year follow up. Although the first choice for treatment of taeniasis is still praziquantel, it may often cause serious side effect on asymptomatic cysticercosis cases to suddenly become symptomatic within a half day of the treatment. Therefore, the problems in treatment of taeniasis and/or cysticercosis in Asia are briefly overviewed, since other platyhelminthic diseases including schistosomiasis, opisthorchiasis etc. are more common and praziquantel is strongly recommended for mass treatment of these trematodiases with no idea on the co-infection with eggs of T. solium which cause asymptomatic cysticercosis.

Abstract
Abstract
Age-related EBV-associated B-cell lymphoproliferative disorder (AR-EBVLPD) is newly classified as a subtype of diffuse large cell lymphoma (DLBCL) according to the WHO classification. AR-EBVLPD cases have poor prognosis compared to that of EBV-negative DLBCL patients. Until now, its molecular pathogenesis remains largely unknown. We investigated gene expression profiling to identify molecular genetic characterization of AR-EBVLPD. Total RNA was extracted from fresh-frozen tumor samples of five AR-EBVLPD and eight EBV-negative DLBCL cases. Expression profiling was studied using the Agilent 44K human oligonucleotide microarray. Genes highly expressed in AR-EBVLPD included inflammatory and immune-related genes. Gene set enrichment analysis and gene ontology analysis showed that gene sets of the JAK-STAT and NF-kB pathways were enriched in AR-EBVLPD cases. In vitro analysis showed that high activation of JAK-STAT and NF-kB pathways was induced by EBV infection into DLBCL cell lines. The immunoprecipitation assay confirmed that the NF-kB pathway was activated in EBV-infected cell lines compared to EBV-naïve cell lines. The protein expression level of phosphorylated STAT3 increased in an EBV-infected cell line according to western blot analysis. A total of 61 patients (25 AR-EBVLPD and 36 EBV-negative DLBCL) were analyzed immunohistochemically for pSTAT3. Protein expression of phospho-STAT3 was frequently observed in lymphoma cells of AR-EBVLPD clinical samples using immunohistochemistry [AR-EBVLPD: (80.0%, n=20/25) vs. EBV-negative DLBCL: (38.9%, n=22/36), p=0.001]. These results suggested that STAT3 and NF-kB activation was characteristic of AR-EBVLPD, which may reflect the nature of EBV-positive tumor cells. Targeting these pathways as therapies might improve clinical outcomes of AR-EBVLPD.

Abstract
Abstract
In order to prepare a porous three-dimensional (3-D) structure in biodegradable polyester materials we have conducted the enzymatic degradation of a poly(L-lactide) (PLLA)-based nano-composite foam, having a nanocellular structure, using proteinase-K as a degrading agent at 37°C. The surface and cross sectional morphologies of the foam recovered after enzymatic hydrolysis for different intervals were investigated by using a scanning electron microscope. The nanocellular material took up a large amount of water, which led to the swelling of the foam due to the large surface area inside the nanocelluar structure, and facilitated the enzymatic degradation of the PLLA matrix as compared with the bulk (pre-foamed) sample. Consequently, we have successfully prepared a porous 3-D structure as a remaining scaffold in the core part of the nano-composite foam, reflecting the spherulites of the crystallized PLLA.

Abstract
The submandibular and parotid glands are the main sources of immunoglobulins A (IgAs) in human and rat saliva. These glands express the polymeric immunoglobulin receptor (pIgR), which transports IgAs into saliva. The main source of IgAs in saliva and pIgR expression in salivary glands has not been well documented in cattle. Expressions of pIgR were determined in the major bovine salivary glands (sublingual, submandibular, and parotid) by RT-PCR for mRNA and by Western blot analysis and immunohistochemistry (IHC) using an anti-human pIgR antibody for protein. The protein detected with the antibody was identified by nano-liquid chromatography-quadrupole time of flight mass spectrometry. Additionally, the distribution of Ig-producing plasma cells was analyzed by IHC. RT-PCR showed that pIgR was expressed in the sublingual and submandibular glands, but not in the parotid gland. Higher protein levels were observed in sublingual glands than in submandibular glands by Western blot. By IHC, pIgR was mainly located on the apical side of the cytoplasmic membrane in the sublingual gland, whereas it was observed only on the basal side in the submandibular gland. The highest density of plasma cells expressing IgAs was observed in the sublingual gland. These results suggest that the sublingual gland plays an important role in first-line defence of the oral cavity in cattle in contrast to humans and rats.

Abstract
Animals exposed to phencyclidine (PCP) during the neonatal period have fewer GABAergic interneurons in the corticolimbic area, including the hippocampus, and exhibit abnormal behaviors after attaining maturation that correspond with schizophrenic symptoms. Since a lack of inhibitory interneurons in the hippocampus has also been reported in postmortem studies of patients with schizophrenia, the deficit may induce abnormal activity of hippocampal neurons that underlies pathological states in schizophrenia. However, it remains unclear how PCP treatment during the neonatal period affects the discharge activity of hippocampal neurons in adulthood. In the current study, single unit responses of hippocampal CA3 neurons to paired auditory clicks were recorded in freely moving mice repeatedly injected with PCP or saline during the neonatal period. The recorded neurons were classified into two subpopulations, narrow-spike neurons and broad-spike neurons, based on the spike width. The spontaneous discharge rate was higher in the narrow-spike neurons than in the broad-spike neurons, indicating that the narrow-spike neurons correspond with hippocampal inhibitory neurons. The proportion of narrow-spike neurons was significantly smaller in neonatally PCP-treated mice than in saline-treated mice. The broad-spike neurons that exhibited a response magnitude to the second click as large as that to the first click (E/E-type response) showed longer response duration to the paired clicks in PCP-treated mice than in the saline-treated mice. Further, the number of neurons with E/E-type response was higher in the PCP-treated mice than in the saline-treated mice. Finally, the attenuation of an auditory-evoked potential component, N40, to the second click (sensory gating) was blunted in the PCP-treated mice when compared with that in the saline-treated mice. These results suggest that the neonatal administration of PCP induced a deficit of inhibitory interneurons and altered discharge activity of neurons in the hippocampal CA3 region to the paired clicks, thereby inducing the deficit in sensory gating.

Abstract
In Japan, amyloidosis is a rare cause of renal failure and of renal transplantation. We treated a patient who underwent a renal transplantation because of chronic renal failure caused by secondary amyloidosis with a good result. The patient was a 50-year-old woman who was diagnosed with secondary amyloidosis and an amyloid kidney. She underwent living donor renal transplantation after about 7 years of hemodialysis. During the 3-year posttransplantation period, she maintained good allograft function with a serum creatinine level about 1.2 mg/dL. Because of amyloidosis is a systemic disease, amyloid kidney patients often experience fatal complications, so the indications for renal transplantation in amyloid patients are still controversial. But if the patient's general condition is good, renal transplantation can be an effective therapy for patients with kidney failure caused by amyloidosis.

Abstract
A 60-year-old male patient with an unknown cause for cirrhosis and a hepatoma underwent an ABO incompatible living donor liver transplantation (LDLT) from his son. The transplanted graft was his son's right lobe. For ABO incompatible transplantation, splenectomy was performed for desensitization. A catheter was inserted into the recipient's right hepatic artery for subsequent local immunosuppression. On the 15th postoperative day, a fusiform 15 × 10 mm aneurysm was observed in the graft right hepatic artery using ultrasonography and hepatic arteriography. At that time, the patient was also diagnosed to have an intraperitoneal abscess at the bottom of his left diaphragm. Administering antibiotics, we tried to embolize the aneurysm because of fear of rupture, but this manever failed because it was difficult to insert the wire in to the aneurysm to produce a stenosis around its proximal neck. However, because the aneurysm was not detectable on the 37th postoperative day, it was assumed to have embolized spontaneously. This relatively rare case revealed a hepatic artery aneurysm that spontaneously regressed after ABO incompatible LDLT.

Abstract
Idiopathic interstitial pneumonias (IIPs) are histopathologically classified into several types, including usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP) and cryptogenic organising pneumonia (COP). We investigated whether periostin, a matrix protein, could be used as a biomarker to assess histopathological types of IIPs. We performed immunohistochemical analyses in each histopathological type of IIP, examined serum levels of periostin in IIP patients and analysed the relationship between serum levels of periostin and the pulmonary functions in patients with idiopathic pulmonary fibrosis (IPF). Periostin was strongly expressed in lungs of UIP and fibrotic NSIP patients, whereas expression of periostin was weak in the lungs of cellular NSIP and COP patients, as well as in normal lungs. Serum levels of periostin in IPF were significantly higher than those of healthy subjects and COP patients. Furthermore, periostin levels in IPF patients were inversely correlated with their pulmonary functions. Thus, we have found that periostin is a novel component of fibrosis in IIP. Periostin may be a potential biomarker to distinguish IIP with fibrosis.

Abstract
Peripheral T-cell lymphoma (PTCL) has a poorer prognosis than diffuse large B-cell lymphoma (DLBCL). We administered the CyclOBEAP regimen (cyclophosphamide, vincristine, bleomycin, etoposide, doxorubicin, prednisolone) to patients with DLBCL, and reported its safety and efficacy. Here, we report the results of a multicentre phase II study of the CyclOBEAP regimen in patients with PTCL. In addition, NME1 remained a prognostic factor for survival, as shown in patients who were treated with CyclOBEAP. There were 84 eligible patients and the median age was 54 years. The 5-year overall survival (OS) rate was 72% and progression-free survival (PFS) rate was 61%. The 5-year OS was 93% among the anaplastic large-cell lymphoma cases, 74% among the angioimmunoblastic T-cell lymphoma cases, and 63% among the cases of PTCL-not otherwise specified. When the patients were divided according to the International Prognostic Index or Prognostic Index for PTCL, the 5-year OS and PFS rates did not significantly differ among the risk groups. Positivity for NME1 was found to be a significant independent prognostic factor. Grade 4 neutropenia was observed in 80 patients and thrombocytopenia in nine patients. Our results suggest that the CyclOBEAP therapy is safe and effective for PTCLs. Furthermore, the NME1 protein may be an important prognostic factor in PTCL.

Abstract
PURPOSE We examined whether nm23-H1 is a prognostic factor of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). EXPERIMENTAL DESIGN We studied 102 consecutive, untreated PTCL-NOS patients from 1998 to 2008. The expression of nm23-H1 and TIA-1 was studied by immunohistochemistry. RESULTS nm23-H1 was positive in 44.1% and TIA-1 in 78.4% of the PTCL-NOS patients. nm23-H1 expression was not correlated with age, performance status (PS), lactate dehydrogenase (LDH) level, or stage but was significantly correlated with the prognostic index for T-cell lymphoma. The serum nm23-H1 level was 43.44 ng/mL in the cytoplasmic nm23-H1 strongly positive, 24.32 ng/mL in the cytoplasmic nm23-H1 moderately positive, and 13.64 ng/mL in the cytoplasmic nm23-H1-negative patients. The nm23-H1-positive group had significantly shorter overall survival (OS). TIA-1 had no prognostic impact on 5-year OS rates. OS was significantly shorter in patients with the following clinicopathologic features: age 60 or more years, PS of 2 to 4, LDH level greater than normal, bone marrow involvement, or nm23-H1-positive lymphoma. Multivariate analysis confirmed nm23-H1 expression to be an independent prognostic factor. CONCLUSIONS The nm23-H1 protein may be an important prognostic factor in PTCL-NOS. Because our results suggested that nm23-HI is produced by lymphoma cells, we expect to see the development of new treatments targeting nm23 overexpression.

Abstract
Although ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) therapy has been regarded as a standard of care for advanced-stage Hodgkin lymphoma (HL) since 1992, there has been no prospective data of ABVD therapy in Japan. To investigate the efficacy and safety of ABVd therapy with the lower dose of dacarbazine (250 mg/m(2)) in patients with newly diagnosed stage II-IV HL, Lymphoma Study Group of Japan Clinical Oncology Group conducted a phase II study. The primary endpoints were complete response rate (%CR) and progression-free survival (PFS). A total of 128 patients with age less than 70 years were enrolled and received 6-8 cycles of ABVd followed by radiation to initial bulky mass. The %CR in 118 eligible patients was 81.4% [95% confidence interval (CI) 73.1-87.9%]. Major toxicity was grade 4 neutropenia (45.3%). Grade 3 nausea/vomiting was the most frequent non-hematological toxicity (10.9%). Transient grade 4 constipation, infection (abscess), hypoxemia and hyperbilirubinemia were observed in 4 patients. No treatment-related death was observed. PFS and overall survival at 5 years were 78.4% (95% CI 70.9-85.9%) and 91.3% (95% CI 86.1-96.5%), respectively. In conclusion, ABVd is effective in Japanese patients with stage II-IV HL with acceptable toxicities (UMIN-CTR Number: C000000092).

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
The R-CHOP regimen has been found to improve the outcome of diffuse large B-cell lymphoma (DLBCL). However, it does not provide a satisfactory treatment outcome in the high-risk group. We previously administered the CyclOBEAP regimen to patients with DLBCL, and reported its safety and efficacy. The R-CyclOBEAP regimen was administered over a total period of 12 weeks, and rituximab 375 mg/m(2) was given every 2 weeks. There were 101 eligible patients. CR was achieved in 96 patients (95%). The 5-year overall survival (OS) rate was 85% and progression-free survival (PFS) rate was 76%. When the patients were divided according to the IPI, the 5-year OS and PFS rates did not significantly differ among the risk groups. The 5-year PFS of the germinal centre B-cell group was 80% and that of the non-GCB group was 74% (NS). Univariate analysis showed that the presence of B symptoms, extranodal lesions >or=2, and sIL-2R were significant poor prognostic factors. Grade 4 neutropenia was observed in 91 patients and thrombocytopenia in 9 patients. The addition of rituximab to CyclOBEAP therapy may enhance the effect of CyclOBEAP therapy for DLBCL.

Abstract
Intravascular large B-cell lymphoma (IVLBCL) is a rare disease entity with a high incidence of central nervous system (CNS) involvement at diagnosis. To evaluate CNS involvement, particularly recurrence including progression on therapy and relapse of IVLBCL, we retrospectively analyzed 109 patients with IVLBCL receiving chemotherapies with or without rituximab. In 82 patients (75%) without CNS involvement at initial diagnosis, risk of CNS recurrence at 3 years was 25% with a median follow-up in survivors of 39 months (range, 2-158 months). In 27 patients (25%) with CNS involvement at initial diagnosis, risk of CNS recurrence at 1 year was 25% with a median follow-up in survivors of 18 months (range, 10-77 months). Duration from diagnosis to CNS recurrence tended to be short in patients with CNS involvement at diagnosis. No significant difference in risk of CNS recurrence was found between patients receiving chemotherapies with or without rituximab. On multivariate analysis skin involvement at initial diagnosis was identified as a predictive factor for CNS recurrence in patients without CNS involvement at diagnosis (hazard ratio, 5.27; 95% confidence interval, 1.59-17.4; P = 0.007). Survival rate after CNS recurrence at 2 years was 12% in patients without CNS involvement at diagnosis. Central nervous system recurrence is a serious complication in IVLBCL patients and optimal strategies for CNS involvement should be established to obtain further improvements to clinical outcomes in the rituximab era.

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
Among methotrexate (MTX)-related lymphoproliferative disorders (MTX-LPD), diffuse large B-cell lymphoma (DLBCL) accounts for about half. We studied the clinicopathological characteristics and prognosis of patients with DLBCL in MTX-LPD. This study included 29 patients who developed DLBCL after receiving MTX for rheumatoid arthritis. MTX was discontinued in all patients. Their median age was 62 years. Elevated lactate dehydrogenase (LDH) level was observed in 97% of the patients, bone marrow involvement in 17%, and involvement of extranodal sites in 41%. As for the cellular immunophenotype, CD20 was positive in 93%, CD5 in 3%, CD10 in 31%, BCL2 in 21%, BCL6 in 69%, and Epstein-Barr virus (EBV)-encoded small non-polyadenylated RNA (EBER) in 24%. Chemotherapy was started within 2 months after MTX withdrawal in 23 patients, of whom 12 patients received combination with rituximab. Spontaneous remission occurred in the remaining six patients. The EEBV-positive rate was 67% (4/6), and the four EBV-positive patients achieved complete response. Among the 23 DLBCL patients treated with chemotherapy, 20 patients achieved complete response. The 5-year overall survival was 74% and the 5-year progression-free survival was 65%. After the development of DLBCL, withdrawal of MTX was the first choice of treatment. Germinal center B-cell type and EBER-positive patients tended to show spontaneous remission. The utility of rituximab should be examined in future studies.

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.
