Abstract
Kaempferia parviflora (KP) rhizome, also called black ginger, has been used as a herbal medicine for many centuries. This current study was aimed at exploring whether KP rhizome extract (KPE) had anti-obesity effects and the mechanism involved. Five-week-old C57BL/6N male mice were allocated into five groups for 8-week feeding with control diet (CD), high-fat diet (HFD), HFD + 150 mg/kg body weight (BW)/day KPE (HFD+K150), HFD + 300 mg/kg BW/day KPE (HFD+K300), and HFD + 600 mg/kg BW/day KPE (HFD+K600). KPE decreased BW, body fat mass, adipose tissue weight, adipocyte size, and serum levels of glucose, triglycerides, cholesterol, insulin, and leptin in HFD-induced obese C57BL/6N mice. KPE inhibited adipogenesis by decreasing CCAAT/enhancer binding protein α, peroxisome proliferator-activated receptor γ, sterol regulatory element-binding protein-1c, acetyl-CoA carboxylase 1, ATP-citrate lyase, and fatty acid synthase mRNA expression. KPE improved lipolysis by increasing carnitine palmitoyl transferase 1 and hormone-sensitive lipase mRNA expression. These results suggest that KPE may have inhibited HFD-induced obesity by regulating several pathways involved in decreasing adipogenesis and enhancing lipolysis. Thus, the results suggest that KPE (or KP) may be applicable as an anti-obesity agent.

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
Visceral fat is a more important factor in obesity-associated disorders in Japanese individuals than in Caucasian individuals. The objective of this randomised, double-blind, placebo-controlled parallel group study, conducted in Japanese overweight adults, was to investigate the effects of polymethoxyflavone purified from Kaempferia parviflora on visceral fat. A total of 80 subjects (aged 20-64 years, 23.0 ≤ body mass index < 30 kg m-2) were randomly assigned in 1 : 1 ratio to either the active (polymethoxyflavone purified from K. parviflora) or placebo group. Over a 12-week period, each subject received two capsules containing polymethoxyflavone purified from K. parviflora (12 mg polymethoxyflavone per day) or placebo. The primary outcome was a reduction in visceral fat area (VFA), while the secondary outcome was a reduction in subcutaneous fat area (SFA) and total fat area (TFA). VFA was measured at 0, 8, and 12 weeks using computed tomography scanning. Results showed that VFA significantly reduced after 12 weeks in the active group and was significantly lower than in the placebo group at 8 and 12 weeks. A significant reduction was observed in SFA and TFA after 8 and 12 weeks in the active group; TFA was significantly lower than that in the placebo group at 8 and 12 weeks. No adverse events associated with the test supplements were observed in either group. Our study shows that administration of polymethoxyflavone purified from K. parviflora reduces visceral fat in Japanese overweight adults.

Abstract
Abstract
Background
Malnutrition is the important factor to cause frailty and sarcopenia which affect the prognosis of cardiovascular diseases. However, the effect of malnutrition on prognosis of coronary artery disease (CAD) patients with myocardial damage is still uncertain.
Purpose
The aim of the present study was to investigate the effect of malnutrition on prognosis of CAD patients with myocardial damage who received percutaneous coronary intervention (PCI).
Methods
The subjects were 241 CAD patients with myocardial damage due to myocardial ischemia by coronary artery stenosis or occlusion. These patients underwent successful revascularization for CAD by PCI using second-generation drug eluting stents and discharged. Geriatric Nutritional Risk Index (GNRI) was used to assess nutritional status in this study, and patients with GNRI<92 at baseline were defined as malnutrition group. The association between MACCE (major cardiovascular and cerebrovascular events) after discharged and patient's characteristics including nutritional status at baseline were assessed.
Results
The mean follow-up period was 546±310 days, with a maximum follow-up duration of 1092 days. MACCE within 3 years after PCI were 42 cases (17%) and malnutrition group had high rate of MACCE (38 vs. 11%, P<0.01) compared with non- malnutrition group. In malnutrition group, age (77±9 vs. 67±11 years, P<0.01) and high-sensitivity C-reactive protein (hs-CRP) level (5.52±6.63 vs. 0.72±1.86 mg/dl, P<0.01) were higher than those of non-malnutrition group. The serum albumin (Alb) level (3.0±0.5 vs. 4.0±0.4 mg/dL, P<0.01), hemoglobin (Hb) (10.4±1.9 vs. 12.8±2.4 g/dL, P<0.01), total cholesterol (151.8±32 vs. 174.1±41.6 mg/dL, P<0.01), triglycerides (96.9±49.1 vs. 140.6±128.3 mg/dL, P<0.01), and left ventricular ejection fraction (LVEF) (50.2±15.9 vs. 55.9±15.3%, P=0.03) were lower in malnutrition group than those in non-malnutrition group. Moreover, malnutrition group had lower rate of hemodialysis (HD) (35 vs. 65%, P<0.01), dyslipidemia (16 vs. 84%, P<0.01) and using of statins (16 vs. 83%, P=0.02) than those in non-malnutrition group. As a result of Cox proportional hazards analysis, MACCE was associated with age [hazard ratio (HR): 1.04, 95% confidence interval (CI): 1.01–1.07, p p<0.01)], hs-CRP (HR: 1.08, 95% CI: 1.03–1.11, p<0.01), HD (HR: 2.63, 95% CI: 1.51–4.58, p<0.01) and malnutrition (HR: 3.69, 95% CI: 2.11–6.42, p<0.01) in the univariate analysis. The multivariate Cox proportional hazards analysis revealed that HD (HR: 2.24, 95% CI: 1.24–4.08, p<0.01) and malnutrition (HR: 2.10, 95% CI: 1.04–4.23, p=0.03) were significantly associated with MACCE. Furthermore, malnutrition additively facilitated incidence of MACCE among patients underwent HD (GNRI <92+HD: HR 4.19, 95% CI: 2.22–7.88, p<0.001, GNRI >92+HD: HR 1.26, 95% CI: 0.65–2.47, p=0.493).
Conclusions
In CAD patients with myocardial damage, malnutrition (GNRI<92) is a major risk factor for MACCE after PCI.

Abstract
This study's aim was to evaluate the safety of daily consumption of Kaempferia parviflora extract (KPE) using a randomized double-blind placebo-controlled study with 52 recruited healthy Japanese subjects. Each subject received five KPE tablets (containing 150 mg of KPFORCE™/tablet) or placebo daily for 4 weeks. There were no adverse events related to KPE intake or any abnormalities compared with placebo group in anthropometric, cardiovascular, blood, and urine parameters during the course of the study. Thus, daily KPE ingestion was found to be safe in healthy Japanese men and women.

Abstract
Kaempferia parviflora (KP), also known as Krachai-dam in Thailand, belongs to the family Zingiberaceae and has been used traditionally to improve blood flow and treat inflammatory, allergic, and gastrointestinal disorders. The objective of this study was to investigate the safety profile of a standardized hydroalcoholic KP rhizome extract via mutagenicity and sub-chronic toxicity evaluations using in vitro and in vivo techniques. The in vitro mutagenicity of KP extract was assessed via reverse mutation tests using Salmonella typhimurium TA98, TA100, TA1535, and TA1537, and Escherichia coli WP2 uvrA. The sub-chronic toxicity profile was evaluated after daily oral administration of KP extract to Sprague-Dawley rats for 90 days. General toxicological parameters were monitored weekly. After the treatment period, blood was collected for hematological and biochemical analyses and certain organs were removed for macroscopic and histopathological analyses. Reverse mutation tests revealed that KP extract did not induce gene mutations at any of the concentrations tested. In the sub-chronic toxicity test, a few changes were observed, including increased salivation in the animals administered high-dose KP extract (249 mg/kg body weight (bw)/day). No toxicologically relevant changes were observed in the biochemical analysis. Sub-chronic administration of KP extract increased platelet levels in animals administered low-dose KP extract (25 mg/kg bw/day). However, the hematological and biochemical parameters remained within normal physiological ranges for the animal species. No toxicological changes were observed in the macroscopic and histopathological analyses performed in this study. These results demonstrate that KP extract is not genotoxic and that 90-day oral administration of the doses tested did not result in toxicity. Therefore, KP extract has a high safety margin for daily use.

Abstract
BACKGROUND The levels of corneal donation are insufficient to meet the demand for corneal transplantation in Japan. To overcome this problem, we started to routinely mention the possibility of corneal donation to the families of patients who died in our hospital's Urology Department in February 2008. In this study, we evaluated the effectiveness of this approach. METHODS We retrospectively reviewed the medical records of the patients who died in the Department of Urology, St. Marianna University School of Medicine Hospital, and analyzed the patients' characteristics and information about corneal donation. RESULTS In total, 211 patients died in our department between February 2008 and March 2017, and 155 patients were medically suitable corneal donors. We mentioned the possibility of corneal donation to 129 (83.2%) families, and 29 (18.7%) families agreed. Three families subsequently withdrew their consent. Finally, 26 (16.8%) of the families that were approached about corneal donation by urologists agreed to donate their relatives' corneas. Another 2 families voluntarily offered to donate their relatives' corneas. Thus, 28 (18.1%) of 155 medically suitable donors donated their corneas for transplantation. Twenty-six (92.8%) donors were 60 years or older and all donors were affected with malignant genitourinary tumors. Fifty-four (96.4%) corneas were successfully transplanted into recipients. CONCLUSIONS Even elderly patients who die of solid carcinoma can be an important source of corneal donors. In this study, we showed that routine referral by urologists increased corneal donation. If this approach were adopted by other departments, it might further increase the number of corneal donations.

Abstract
PURPOSE Obesity is a serious problem, which is now a worldwide health problem. Kaempferia parviflora extract (KPE) exhibits anti-obesity effects in animals. However, as no clinical trials have evaluated the anti-obesity effects of KPE in humans, we examined the effects of KPE in reducing abdominal fat in overweight and preobese Japanese subjects. MATERIALS AND METHODS A 12-week, single-center, randomized, double-blind, placebo-controlled clinical trial was conducted. Seventy-six subjects (males and females aged 20 to <65 years) with a body mass index ≥24 and <30 kg/m2 were randomly assigned into two groups. The subjects in each group ingested one capsule of placebo or active KPE (containing 150 mg of KPE) once daily for 12 weeks. The primary outcome was reduction in visceral fat area as determined by computed tomography scanning. The key secondary outcomes were reductions in subcutaneous fat area and total fat area. Subgroup analysis was also performed in healthy subjects without dyslipidemia, hypertension, or hyperglycemia. The safety of KPE ingestion was also evaluated. RESULTS Compared with the placebo group, the active KPE group exhibited significant reduction in abdominal fat area (visceral, subcutaneous, and total fat) and triglyceride levels after 12 weeks. Subgroup analyses demonstrated a significant reduction in abdominal fat area and triglyceride levels in healthy subjects compared with the placebo group after 12 weeks. Neither group exhibited adverse events related to the test foods or clinically relevant abnormal changes in physical, biochemical, or hematologic parameters, or in urinalysis results and medical interview. CONCLUSION Daily ingestion of KPE safely reduces body fat, particularly abdominal fat, in Japanese overweight and preobese subjects.

Abstract
This study examines the effects of DEP components on circulatory CC and CXC chemokines, potent activators and chemoattractants for macrophage and leukocyte subpopulations, in a murine model of lung inflammation. 1CR mice were divided into six experimental groups which received intratracheal inoculation of vehicle, LPS alone (2.5 mg/kg), organic chemicals in DEP (DEP-OC: 4 mg/kg) extracted with dichloromethane, residual carbonaceous nuclei after the extraction (washed DEP: 4 mg/kg), DEP-OC + LPS, or washed DEP + LPS. Intratracheal instillation of each DEP component alone did not significantly change the circulatory level of macrophage inflammatory protein (MIP)-1α, MIP-2, and macrophage chemoattractant protein-1 (MCP-1) 24 h after the exposure as compared with vehicle instilled alone. In the LPS group, MCP-1, but not MIP-1α or MIP-2, was significantly greater than in the vehicle group. The combined administration of LPS and washed DEP caused a further three to five-fold increase in MIP-1α, MIP-2, and MCP-1 proteins in the serum as compared with LPS administered alone. No significant difference between the LPS + DEP-OC group and the LPS group was observed. These results indicate that pulmonary exposure to washed DEP enhances circulatory level of chemokines during lung inflammation. The enhancement may be important in the aggravations of systemic inflammatory responses and ischemic cardiovascular conditions associated with air pollution.

Abstract
AIM To elucidate the distribution and circulation dynamics of Campylobacter and Salmonella in Japanese chicken broiler flocks. METHODS AND RESULTS A 2-year investigation of the distribution of Campylobacter and Salmonella was conducted in 25 broiler flocks at nine farms in Japan from 2013 to 2014. Campylobacter and Salmonella tested positive in 11 (44·0%) and 24 (96·0%) broiler flocks respectively. One hundred and ninety-five Campylobacter and 184 Salmonella isolates were characterized into 12 Campylobacter (including two novel genotypes) and three Salmonella MLST genotypes. Only Salmonella isolation between caecal and environmental samples were significantly correlated. Further, one litter sample tested positive for Salmonella before new chicks were introduced. The Campylobacter strains rapidly lost culturability within 2-18 days; in contrast, the Salmonella strains survived from 64-211 days in artificially inoculated water samples. CONCLUSION No persistent circulation-mediated Campylobacter contamination was observed. In contrast, circulation of Salmonella in broiler houses was seen, apparently due to the litter excreted from broiler flocks, as well as Salmonella-contaminated water and feed. SIGNIFICANCE AND IMPACT OF THE STUDY This paper provides the distribution, genotypic data and circulation dynamics of Campylobacter and Salmonella as recently observed in Japanese chicken broiler farms.

Abstract
BACKGROUND AND PURPOSE Fab fragments (Fabs) of antibodies have the ability to bind to specific allergens but lack the Fc portion that exerts effector functions via binding to receptors including FcεR1 on mast cells. In the present study, we investigated whether intranasal administration of the effector function-lacking Fabs of a monoclonal antibody IgG1 (mAb, P1-8) to the major allergen Cry j1 of Japanese cedar pollen (JCP) suppressed JCP-induced allergic rhinitis in mice. EXPERIMENTAL APPROACH Balb/c mice sensitized with JCP on days 0 and 14 were challenged intranasally with the pollen on days 28, 29, 30 and 35. Fabs prepared by the digestion of P1-8 with papain were also administered intranasally 15 min before each JCP challenge. KEY RESULTS Intranasal administration of P1-8 Fabs was followed by marked suppression of sneezing and nasal rubbing in mice with JCP-induced allergic rhinitis. The suppression of these allergic symptoms by P1-8 Fabs was associated with decreases in mast cells and eosinophils and decreased hyperplasia of goblet cells in the nasal mucosa. CONCLUSIONS AND IMPLICATIONS These results demonstrated that intranasal exposure to P1-8 Fabs was effective in suppressing JCP-induced allergic rhinitis in mice, suggesting that allergen-specific mAb Fabs might be used as a tool to regulate allergic pollinosis.

Abstract
We report on dynamical interference between short-lived Rabi oscillations and long-lived coherent phonons in CuCl semiconductor microcavities resulting from the coupling between the two oscillations. The Fourier-transformed spectra of the time-domain signals obtained from semiconductor microcavities by using a pump-probe technique show that the intensity of the coherent longitudinal optical phonon of CuCl is enhanced by increasing that of the Rabi oscillation, which indicates that the coherent phonon is driven by the Rabi oscillation through the Fröhlich interaction. Moreover, as the Rabi oscillation frequency decreases upon crossing the phonon frequency, the spectral profile of the coherent phonon changes from a peak to a dip with an asymmetric structure. The continuous wavelet transformation reveals that these peak and dip structures originate from constructive and destructive interference between Rabi oscillations and coherent phonons, respectively. We demonstrate that the asymmetric spectral structures in relation to the frequency detuning are well reproduced by using a classical coupled oscillator model on the basis of dynamical Fano-like interference.

Abstract
BACKGROUND AND PURPOSE Mast cell hyperplasia has been observed in the lungs of mice with experimental asthma, but few reports have studied basophils. Here, we attempted to discriminate and quantify mast cells and basophils in the lungs in a murine asthma model, determine if both cells were increased by multiple antigen challenges and assess the roles of those cells in asthmatic responses. EXPERIMENTAL APPROACH Sensitized Balb/c mice were intratracheally challenged with ovalbumin four times. Mast cells and basophils in enzymatically digested lung tissue were detected by flow cytometry. An anti-FcεRI monoclonal antibody, MAR-1, was i.p. administered during the multiple challenges. KEY RESULTS The numbers of both mast cells (IgE(+) C-kit(+) ) and basophils (IgE(+) C-kit(-) CD49b(+) ) increased in the lungs after three challenges. Treatment with MAR-1 completely abolished the increases; however, a late-phase increase in specific airway resistance (sRaw), and airway eosinophilia and neutrophilia were not affected by the treatment, although the early-phase increase in sRaw was suppressed. MAR-1 reduced antigen-induced airway IL-4 production. Basophils infiltrating the lung clearly produced IL-4 after antigen stimulation in vitro; however, histamine and murine mast cell protease 1 were not increased in the serum after the challenge, indicating that mast cell activation was not evoked. CONCLUSION AND IMPLICATIONS Both mast cells and basophils infiltrated the lungs by multiple intratracheal antigen challenges in sensitized mice. Neither mast cells nor basophils were involved in late-phase airway obstruction, although early-phase obstruction was mediated by basophils. Targeting basophils in asthma therapy may be useful for an early asthmatic response.

Abstract
Kaempferia parviflora (KP) is a member of the ginger family and is known in Thailand as Thai ginseng, Krachai Dam or Black Ginger. TheK. parviflora extract (KPE) was previously reported to have a number of physiological effects; however, the antiobesity effects of KPE and its mechanisms remain to be elucidated. In this study, we conducted KPE feeding experiments (low dose: 0.5% KPE, high dose: 1.0% KPE) in mice to examine the antiobesity effects. For both 0.5% KPE and 1.0% KPE, 7 weeks' feeding of KPE contained in a high-fat diet (HFD) significantly decreased body weight gain, intraabdominal fat accumulation, and plasma triglyceride and leptin levels. Concurrently, KPE administration increased oxygen consumption in mice fed on a HFD. We also found that 1.0% KPE feeding significantly increased the uncoupling protein 1 (UCP1) expression in brown adipose tissue (BAT). Moreover, KPE administration increased urinary noradrenaline secretion levels. These results demonstrate that KPE promotes energy metabolism by activation of BAT, at both doses and up-regulation of UCP1 protein at a high dose. Although numerous challenges remain, the present study demonstrated that KPE suppresses HFD-induced obesity through increased energy metabolism.

Abstract
Background In the tumor microenvironment, factors inhibiting the targeting of cancer cells by activated T cells have recently been noted. B7-H3 belongs to the B7 superfamily of immune regulatory ligands and plays an important role in the adaptive immune response of co-inhibitory/stimulatory factors in regulating T cells. However, the degree to which B7-H3 directly affects tumor immune evasion mechanisms remains unclear, particularly in patients with breast cancer. Regulatory T cells (Tregs) are known as a key player in the inhibition of immune mechanisms. The present study demonstrated that expression of B7-H3 on tumor cells and the number of Tregs in the tumor microenvironment independently affected prognosis in breast cancer patients. Methods We immunohistochemically investigated the presence of B7-H3 and forkhead box P3 (Foxp3)-positive Tregs in pathological specimens from 90 patients with breast cancer. Results Positive B7-H3 expression was associated with shorter recurrence-free survival (RFS) (p = 0.014). A higher percentage of Foxp3-positive cells also correlated with shorter RFS (p = 0.039). Multivariate analysis showed B7-H3 as an independent factor on RFS. Foxp3 expression in tumor-infiltrating lymphocytes (TILs) correlated significantly with larger tumor size (>2 cm), expression of human epidermal growth factor receptor 2 (HER2), and higher nuclear grade (p = 0.003, p < 0.001, p = 0.001, respectively). No correlation was identified between expression of B7-H3 and the percentage of Foxp3-positive TILs. Conclusions B7-H3 and Foxp3 can be regarded as markers of poor prognosis in breast cancer. These expressions were not correlated, suggesting that B7-H3 expression plays an independent role in tumor immune evasion, regardless of Tregs.

Abstract
Abstract Spinal lesions in upper and sublaxilar cervical vertebrae were studied radiologically in 263 patients (25 men and 238 women) with rheumatoid arthritis (RA). Their average age was 58.9 years, and their disease duration was ranged from 6 months to 24 years (mean 13 years). Functional lateral views of the cervical spine were made. Atlantaxial subluxation (AAS) and vertical subluxation (VS) were evaluated as upper cervical lesions. Subaxilar subluxation (SAS) and endplate erosion were evaluated as subaxilar cervical lesions. One hundred and seventy-eight (67.7%) of the patients had a cervical lesion. Upper and subaxilar cervical abnormalities were recognized in 136 (51.7%) and 113 (43.0%) patients, respectively. There was no linkage between upper and subaxilar cervical lesions. While the prevalence of these lesions increased with time, the frequency was found to be over 50% within only 5 years from onset in patients with mutilating deformity. This prevalence tended to be associated with disease activity.

Abstract
BACKGROUND Because few curative treatments are available for food allergy, we investigated the therapeutic potential of rapamycin, a mammalian target of rapamycin (mTOR) inhibitor, on mouse food allergy. METHODS The preventive and therapeutic effects of oral rapamycin on anaphylactic symptoms induced by oral ovalbumin (OVA) challenge in food allergy mice were investigated. Mast cell functions in response to rapamycin were also measured in the passive systemic anaphylaxis model and bone marrow-derived mast cells (BMMCs). RESULTS Daily rapamycin from the first challenge (preventive protocol) attenuated food allergy symptoms including diarrhea, anaphylactic reactions, and hypothermia in mice. The treatment decreased the challenge-induced increases in mouse mast cell protease-1 in serum and mast cell numbers in the intestine. Notably, the mice that already showed food allergy symptoms by previous challenges recovered from the disease with daily administration of rapamycin (therapeutic protocol). Anti-OVA IgG1 and IgE levels in serum, as well as IFN-γ, IL-4, IL-13, IL-9, IL-10, and IL-17 secretion from splenocytes, were decreased by the treatments. In contrast, a single dose of rapamycin failed to affect passive systemic anaphylaxis. Spontaneous and IL-9-dependent survival and IgE-induced IL-13 secretion, but not degranulation, of BMMCs were reduced by rapamycin. CONCLUSION Our data show that mouse food allergy was attenuated by rapamycin through an immunosuppressive effect and inhibition of intestinal mast cell hyperplasia. Inhibition of the IL-9 production-mast cell survival axis is one of the mechanisms of the therapeutic effect of rapamycin. Rapamycin and other mTOR inhibitors might be good candidates for therapeutic drugs for food allergy.

Abstract
BACKGROUND Systemic and oral antigen-induced anaphylaxes are mediated by immunoglobulin (Ig) E and mast cells, but there is no satisfactory treatment for the life-threatening allergic reaction. We investigated the potential of the multitargeted receptor tyrosine kinase inhibitor sunitinib to relieve anaphylactic reactions in food allergy and systemic anaphylaxis. METHODS Efficacy of oral sunitinib on oral and parenteral antigen-induced anaphylaxes in Balb/c mice was evaluated. IgE-dependent degranulation and growth of rat basophilic leukemia RBL2H3 and bone marrow-derived mast cells (BMMCs) in response to sunitinib were investigated. RESULTS Daily administration of sunitinib throughout antigen challenges prevented oral antigen-induced anaphylaxis including diarrhea, anaphylactic symptoms, and hypothermia. The mouse mast cell protease (MMCP)-1 concentration in serum and mast cell number in intestinal tissue after challenge were also decreased by the treatment. Spleen cells from sunitinib-treated mice contained smaller numbers of antigen-specific IgG-producing cells and secreted lower amounts of both Th1 and Th2 cytokines than those of the control mice, whereas the levels of antigen-specific antibodies in serum were not decreased. The reactions and MMCP-1 release in oral antigen-induced anaphylaxis and passive systemic anaphylaxis were attenuated even by a single predose of sunitinib. Degranulation and growth of RBL2H3 cells and BMMCs were greatly reduced by sunitinib. CONCLUSION These results suggested that sunitinib relieves systemic and oral antigen-induced anaphylaxes by the prevention of mast cell activation and hyperplasia in intestinal tissue directly and indirectly through an immunosuppressive effect. Sunitinib and its related kinase inhibitors might be potential drugs for the treatment of food allergy and systemic anaphylaxis.

Abstract
We investigated whether Aspergillus oryzae lectin (AOL), a fucose-specific lectin, induces anaphylactoid reactions and mast cell activation. The injection of AOL into footpads of mice produced a dose-related acute paw oedema. The AOL-induced oedema was attenuated by predose of histamine H1 receptor blocker or pretreatment of the lectin with fucose before injection and was not observed in SCID and mast cell-deficient WBB6F1-W/Wv mice. These results suggested that the AOL-induced anaphylactoid reaction was mediated by histamine released from mast cells. In addition, the activation of mast cells was seemed to be induced by the crosslinking of IgE on the cell surface following the binding of AOL to fucose residues in IgE. Consistent with the in vivo results, AOL induced the degranulation of the rat mast cell line RBL2H3 sensitized with monoclonal IgE. As AOL induced the increase in intracellular Ca(2+) concentration of IgE-sensitized RBL2H3 cells as well as antigen stimulation, AOL could input signals from FcεRI. The degranulation of IgE-sensitized RBL2H3 cells by AOL was diminished by pretreatment of AOL with fucose. Defucosylated IgE did not induce degranulation of RBL2H3 cells in response to AOL stimulation, in spite of its ability to induce degranulation by antigen stimulation as intact IgE. These results indicated that AOL bound to fucose residue of IgE causing antigen-independent IgE-mediated mast cell activation and anaphylactoid reactions in vitro and in vivo, respectively. AOL bound to human IgE as well as to mouse IgE, suggesting the possible implication of AOL in the allergic response to Aspergillus oryzae in humans.

Abstract
BACKGROUND AND PURPOSE Fab fragments (Fabs) of antibodies maintain the ability to bind specific antigens, but lack the binding site for complement as well as the site for binding to receptors on effector cells, such as macrophages that play an important role in inflammation. In the present study, we investigated whether Fabs specific for ovalbumin (OVA) were specifically able to suppress anti-OVA antibody-mediated arthritis (AOA-MA) in mice. EXPERIMENTAL APPROACH AOA-MA was induced by i.v. injection of purified anti-OVA antibodies into naïve mice followed by intra-articular (left ankle) challenge with the antigen. Anti-OVA Fabs prepared by digestion of anti-OVA antibodies with papain were injected i.v. immediately after administration of the intact antibodies. Normal Fabs were used as a control. Arthritis was assessed by thickness of the joints (caliper) and by histology of paw sections, stained with haematoxylin and eosin. KEY RESULTS AOA-MA was markedly suppressed by anti-OVA Fabs, but not by control Fabs. Histologically, mice treated with control Fabs showed marked oedema of synovial tissues with a large number of inflammatory cells including neutrophils, whereas animals given anti-OVA Fabs had mild oedema of the synovium and sparse infiltration of such cells. The antigen-specific suppression of joint inflammation by anti-OVA Fabs was associated with reduced consumption of complement. In vitro studies showed that anti-OVA Fabs significantly blocked the binding of intact anti-OVA antibodies to OVA. CONCLUSIONS AND IMPLICATIONS Antibody-mediated arthritis appears to be specifically down-regulated by Fabs that competitively inhibit the binding of antibodies to antigens.

Abstract
Slope (or plate) cultures of thiostrepton-producing Streptomyces azureus (ATCC 14921) often showed spontaneously developing plaques. Plaques increased in number during serial subcultures. The production of aerial mycelia and sporulating aerial hyphae was interrupted by the overlapping plaques, whereas the growth of substrate mycelia continued in the plaques. These abnormal (eroded) cultures were easily restored to their normal conditions once they were passed through liquid cultures under shaking conditions. A few phage particles were found in the plaques, together with some headless tails and numerous tail tips which formed a hexagonal crystal or a large crystal mass when viewed in an electron microscope. No lytic phenomenon and no phage production were found in the liquid cultures, although all mycelia and spores harbored phage-producing abilities. It was also found that the propagation of phages was successful in solid culture, but not in liquid culture. The whole phage was named SAt2, which belongs to group B of Bradley's morphological classification. From these results, it is considered that S. azureus is lysogenic with temperate phage SAt2, of which virulent mutants are able to infect the aerial mycelia and sporulating hyphae of their lysogenic host.

Abstract
We have previously demonstrated the protective role of interleukin (IL)-6 against septic lung injury induced by lipopolysaccharide (LPS) using IL-6 knock-out (−/−) mice. This protection is mediated, at least partly, through the inhibition of the enhanced local expression of proinflammatory cytokines. In the present study, we addressed whether IL-6 regulates oxidative stress in the lung generated by LPS exposure using IL-6 (−/−) and corresponding wild type (WT) mice. Intraperitoneal LPS (1 mg/kg) challenge induced transcriptional expressions of inducible nitric oxide synthase and heme oxygenase −1 in the lung of mice with both genotypes. In the presence of LPS, these expressions were significantly greater in IL-6 (−/−) than in WT mice. Immunohistochemistry also showed that LPS induced a significant increase in 8-hydroxy-2′-deoxyguanosine formation in the lung as compared to vehicle. Furthermore, the formation was more intense in IL-6 (−/−) than in WT mice in the presence of LPS challenge. In the presence of LPS, lipid peroxidation in the lung was significantly greater in IL-6 (−/−) than in WT mice. These data suggest that the possible mechanisms in which endogenous IL-6 protects against septic lung injury induced by LPS involve, at least in part, its antioxidative properties.

Abstract
The present study was designed to investigate the effect of sinomenine (SIN), an alkaloid extracted from sinomenium acutum on collagen-induced arthritis (CIA) in mice. For this investigation, mice were s.c. immunized with type II collagen (CII) emulsified with complete Freund's adjuvant (day 0). Varying doses of SIN were orally administered daily commencing on day 0 daily over a period of 55 days. The severity of arthritis was evaluated according to clinical score, the effect of SIN on immune responses were determined by measurement of proliferative responses of spleen cells, antibody levels in serum and cytokine assays. Anti-CII IgG2a and IFN-gamma were measured as indicators of Th1 immune responses and anti-CII IgG1, IgE and IL-5 as those of Th2 responses. IL-10 and TGF-beta were measured as indicators of T cell regulator responses. The results showed that treatment with SIN was followed by decreases in the incidence and severity of CIA, anti-CII IgG and the antigen-specific splenocyte proliferation. Production of all isotypes of antibodies including anti-CII IgG2a, IgG1 and IgE as well as secretion of cytokines such as IFN-gamma and IL-5 were suppressed by SIN. In addition, SIN enhanced the secretion of TGF-beta while it had no obvious effect on production of IL-10. These results suggest that the anti-arthritic effect of SIN may be related to the suppression of both Th1 and Th2 immune responses. TGF-beta may at least in part contribute to the suppression of Th1 as well as Th2 immune responses.

Abstract
Ambient particulate matter (PM) exacerbates allergic airway diseases. Our previous study showed that diesel exhaust particles, the main constituents in urban PM, enhance airway hyperresponsivness in mice. In addition, health effects of PM with a diameter of less than 100 nm, called nanoparticles, have been reported, and we have also demonstrated that carbon nanoparticles exacerbate antigen-related airway inflammation. The present study investigates the effects of pulmonary exposure to two sizes of carbon nanoparticles on lung physiology and lung expression of Muc5ac in the presence or absence of antigen in mice. Nanoparticles alone or ovalbumin (OVA) alone moderately enhanced cholinergic airway reactivity, as assessed by total respiratory system resistance (R) and Newtonian resistance (Rn). In the nanoparticle + OVA groups, all the parameters for lung responsiveness, such as R, compliance, elastance, Rn, tissue damping, and tissue elastance, were worse than those in the vehicle group, the corresponding nanoparticle groups or the OVA group. The lung mRNA level for Muc5ac was significantly higher in the OVA group than in the vehicle group, and further increased in the nanoparticle + OVA groups than in the OVA or the nanoparticle groups. These data suggest that carbon nanoparticles can enhance lung hyperresponsiveness, especially in the presence of antigen. The effects may be mediated, at least partly, through the enhanced lung expression of Muc5ac.

Abstract
The Cre recombinase of bacteriophage P1 is a powerful tool for artificial modification of genomic function in mammalian cells. To date, many researchers have studied the enzymatic biochemistry of Cre recombinase in loxP site-specific cleavage and rearrangement, as well as its use in gene technology. However, the intricate mechanisms of Cre-mediated recombination are still poorly understood. For example, more knowledge is needed in order to understand Cre recombinase's dependency on cell cycle, the necessity of other factors for recombination, and the exact nuclear environment that's required at the target locus, in order for recombination to take place in eukaryotic cells. In this study, we showed that P1 Cre-mediated recombination occurred frequently during S-phase of the cell cycle. HeLa cells were synchronized in cell cycle with the thymidine-hydroxyurea block method, and recombinant Cre proteins were fused with HIV-1 TAT protein transduction domains (PTD) in every phase of the cell cycle. Results showed that the transduction of PTD-Cre gave rise to genomic recombination preferentially during the S-phase of cell cycle. These findings will contribute significantly to the development of the Cre/loxP recombination system in vivo.

Abstract
15050 Background: Paclitaxel (PTX) and 5’-DFUR have single-agent activity in gastric cancer and have distinct mechanisms of action and no overlap of key toxicities. Synergistic interaction between PTX and 5’-DFUR is mediated by taxane-induced up-regulation of thymidine phosphorylase, which converts 5’-DFUR to 5-FU. We conducted a combination phase II study of PTX and 5’-DFUR in patients with unresectable or recurrent gastric cancer to evaluate the efficacy and safety in an outpatient. Methods: Eligibility criteria included patients with histologically proven unresectable or recurrent gastric cancer who had measurable lesions fitting RECIST, up to one prior chemotherapy, a performance status of 0–2 and adequate organ function. According to our results of phase I study (Proc ASCO 2004, Abstr. 4228), the treatment included PTX 70 mg/m2 i.v. on days 1, 8, and 15 every 4 weeks and 5’-DFUR 600 mg/body p.o. everyday until there was disease progression or the appearance of unacceptable toxicity. Primary endpoint was: RR; and secondary endpoints were OS, PFS, TTF and onset rate of adverse events. Results: Between June 2004 and July 2006, 42 patients were enrolled in this study: including 34 men; 8 women; median age of 70 years (range, 44–85 years); and PS levels were, zero with 27, one with 13 and two with 2 patients. In 42 eligible patients, clinical usefulness was evaluated resulting in response rate of 40.5% (CR, 1; PR, 16; SD, 17; PD, 6; and NE, 2 patients). The first-line therapy involved 28 patients in whom the response rate was 50.0%. The second-line therapy involved 13 patients (all TS-1 failure) in whom the response rate was 23.1%. OS was 371 days, PFS was 170 days and TTF was 147 days. All patients were treated in outpatient. Severe adverse events were found in 2 patients to discontinue the present treatment, though other adverse events were relatively mild without death due to the present therapy. Commonly observed grade 3/4 adverse events were neutropenia (26.2%), appetite loss (4.8%), neuropathy (4.8%), and fatigue (4.8%). Conclusions: The outpatient combination of a weekly PTX and 5’-DFUR chemotherapy is active and well tolerated. No significant financial relationships to disclose.

Abstract
14511 Background: We have presented at 2006 ASCO annual meeting about a genetic UGT1A1 polymorphism oriented phase (P) I study of Irinotecan and 5’-DFUR for metastatic colorectal cancer (MCRC) to determine the maximum tolerated dose (MTD) and the recommend doses (RD) for each UGT1A1 *1/*1 and *1/*28 genotypes. The RD of biweekly Irinotecan administration was 150 mg/m2 for patients (pts) with wild *1/*1 genotype and 70 mg/m2 of Irinotecan for mutated *1/*28. Now we are carrying out a *28 oriented P II study based on this RD. Here we report the profiles of toxicities in the P II study of irinotecan and 5’-DFUR to analyze other kinds of UGT1As polymorphisms in relation to irinotecan toxicities. Patients & Methods: Eligibility criteria were as follows; histologically proven CRC with unresectable metastatic lesions, PS 0–1, age<76, adequate organ functions, and written informed consent. Twenty one pts with wild type genotype and 9 pts with mutated genotype were enrolled. Irinotecan was infused 150 mg/m2 for pts with *1/*1 genotype and 70 mg/m2 for *1/*28. Hematological and non-hematological toxicities were graded, and UGT1As polymorphisms (UGT1A1*6 and *7, UGT1A7*1*2*3*4, UGT1A9*22) were analyzed. Results: Grade (G)3 & 4 toxicities were observed in 6 of 22 (27%) wild type pts and in 3 of 9 (33%) mutated pts, and in 9 of 31 (29%) all pts. There was no significant difference on the profiles of toxicities between the pts with wild genotype and mutated genotype, irrespective of the difference of the quantity of irinotecan. So, the RD was thought to be adequate. In pts with UGT1A1*6 allele, G3 & 4 toxicities were observed 6/11 (55%), on the other hand 3/20 (15%) in pts without *6 allele (p=0.038). G3 & 4 toxicities were also more frequent in pts with UGT1A7*3 alleles than pts without *3 allele (p<0.10). Conclusions: The profiles of toxicities of pts with *1/*1 or *1/*28 genotypes were similar irrespective of the difference of the quantity of irinotecan. The result indicated that the RD of latest PI for each group was adequate, and this P II study is suitable to analyze other kinds of polymorphisms that have correlation to irinotecan toxicities. UGT1A1*6 and UGT1A7*3 allele will be a novel predictor for toxicity of irinotecan. No significant financial relationships to disclose.

Abstract
15084 Background: Of patients who undergo R0 resection for GC with serosal invasion (T3–4), more than half recur mainly in the peritoneum, while TXL and S1 exhibited efficacy for diffuse type and peritoneal metastases in the phase II studies. Primary analysis of the sequential chemotherapy with TXL/S1 had shown its safety and tolerability, its survival benefit is being tested in a large phase III study (the SAMIT trial) with oral fluoropyrimidines as controls. The analysis for survival of this preceding phase II study is performed. Methods: Eligibility criteria included histologically proven GC; sT3–4; sN0–2; M0 (except peritoneal cytology: CY); post D2–3 gastrectomy and R0–1; ECOG PS 0–1; and 20–80 years old. On postoperative day 14 to 56, patients received 3 courses of weekly TXL (80mg/m2 on day 1, 8 for the 1st course and on day 1, 8, 15 for the 2nd and 3rd courses, repeated every 3 or 4 weeks) followed by 4 courses of S1 (80mg/m2 daily for 2 weeks, repeated every 3 weeks). The primary endpoints were % of patients who completed all 7 courses (compliance) to see whether the lower 95% confidence limit of compliance was greater than 69% and incidence of severe toxicities and the secondary endpoints were 3-year survival and toxicities. Results: 50 patients were accrued from May 2003 to March 2004. The median age was 63 (range 34–74); male/female: 34/16; pT2/T3/T4: 1/44/5; CY0/CY1: 4/46; f-stage2/3a/3b/4: 12/15/16/7. The overall compliance was 84%. Median follow up time was 1063 days for survivors (694–1332) and 1030 days for all. Three-year DFS were 64.6% for all, 66.1% for CY0 and 50.0% for CY1. Conclusions: Sequential TXL/S1 may serve as an active adjuvant for gastric cancer patients especially who are at high risk for peritoneal spread. No significant financial relationships to disclose.
