Abstract
Adalimumab (ADA) trough level and anti-ADA antibody (AAA) positivity influence mucosal healing and loss of response in patients with inflammatory bowel disease (IBD). In this study, we clarified the correlation between ADA monitoring, including non-trough level, and real-world IBD clinical outcomes. This retrospective, observational, single-center study involved patients with ulcerative colitis (19) and Crohn's disease (33) treated with ADA from January 2007 to August 2018. Serum ADA and AAA levels were measured 4‒14 days after ADA administration. The AAA positivity rate was 23.1% (12/52). ADA continuity was higher in AAA-negative patients than in AAA-positive patients (P = 0.223). Receiver operating characteristic (ROC) analysis revealed that a serum AAA cut-off of 9.2 μg/mL was associated with ADA continuity. The ADA level was significantly higher in the endoscopic remission group than in the non-remission group (P = 0.02). Based on the ROC curve analysis results of serum ADA level and endoscopic remission, the cut-off value of the serum ADA level was set to 11.1 μg/mL. Under the combined use of ADA with immunomodulators and AAA positivity, ADA continuity was significantly higher when the serum AAA level at 4-14 days after ADA administration was ≥9.2 μg/mL. Furthermore, endoscopic remission can be expected with a serum ADA level of ≥11.1 μg/mL. Overall, to predict clinical outcomes, it would be useful to measure the blood level of ADA regardless of the timing of the trough.

Abstract
Localized thyroid diffuse large B-cell lymphoma stage with stage IE according to the Ann Arbor clinical staging system was diagnosed in a 75-year-old woman. The patient was treated with three courses of chemotherapy followed by radiotherapy. Positron emission tomography/computed tomography (PET-CT) using 2-deoxy-2-[F-18] fluoro-D-glucose (FDG) PET-CT was performed two months after chemotherapy showed increased FDG uptakes in systemic lymph nodes and gluteal muscles. Standardized uptake value in the region of interest ranged from 7.1-26.1. Since it seemed too sudden to be a recurrence, a repeat biopsy was performed from inguinal lymph nodes. Histology revealed that there were no malignant lymphoma cells but noncaseous epithelioid granuloma with multinucleated giant cells. Taken together with the findings of bilateral hilar mediastinal lymphadenopathy and elevated serum angiotensin converting enzyme (ACE) levels (32.4 U/l), sarcoidosis secondary to lymphoma was diagnosed in this patient. Subsequently, both FDG uptake and serum ACE gradually improved without any therapy. The present case strongly suggests the importance of a re-biopsy when the clinical course of recurrence is unusual.

Abstract
BACKGROUND & AIMS The new curcumin derivative Theracurmin® has a 27-fold higher absorption rate than natural curcumin powder. Theracurmin® is an inhibitor of nuclear factor-κB, which mediates the expression of inflammatory cytokines. The effect of Theracurmin® on inflammatory bowel disease in humans has not been explored; therefore, we investigated the efficacy and safety of Theracurmin® in patients with Crohn's disease. METHODS In this randomized, double-blinded study performed at 5 independent medical centers in Japan, Theracurmin® (360 mg/day, n = 20) or placebo (n = 10) was administered to patients with active mild-to-moderate Crohn's disease for 12 weeks. The agent's efficacy was assessed by evaluating clinical and endoscopic remission, healing of anal lesions, and blood levels of inflammatory markers. RESULTS In the Theracurmin® group, a significant reduction in clinical disease activity was observed in week 12 relative to that in week 0 (p = 0.005). On intention-to-treat analysis, clinical remission rates were 35%, 40%, and 40% at weeks 4, 8, and 12, respectively, which were significantly higher than those in the placebo group (all 0%; p = 0.033, p = 0.020, and p = 0.020, respectively). Furthermore, reduction in endoscopic Crohn's disease severity (p = 0.032) was observed at week 12 in the Theracurmin® group. The endoscopic remission rates were 15% and 0% in the Theracurmin® and placebo groups, respectively. Significant healing of anal lesions (p = 0.017) was observed at week 8 in the Theracurmin® group. No serious adverse events were observed in either group throughout the study. CONCLUSIONS Theracurmin® shows significant clinical and endoscopic efficacy together with a favorable safety profile in patients with active mild-to-moderate Crohn's disease.

Abstract
It has become evident that positron emission tomography/computed tomography (PET-CT) using 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) (FDG PET-CT) can detect anti-tumor immune response induced by various immunotherapies. To evaluate whether FDG PET-CT could detect anti-cancer immune response caused by cancer vaccine therapy, we performed a retrospective analysis of FDG PET-CT imaging of patients who were treated with Wilms Tumor 1 (WT1) vaccine therapy in Osaka University during July 2008 and June 2018. Increased FDG uptakes were detected in WT1-vaccinated skin and their draining lymph nodes during the repeated vaccination. While the FDG uptakes seemed to decrease with time after the cessation of WT1 peptide vaccinations, persistence of FDG uptakes for years in WT1-vaccinated skin were also observed in 2 cases who showed good clinical course. Moreover, the FDG uptakes of patients treated with the combination vaccine of WT1 specific cytotoxic T cell (CTL) and helper peptides were significantly stronger than of those treated with the WT1 CTL peptide alone. Since it is evident that the combination vaccine can induce a more robust anti-tumor immunity than can CTL peptide vaccine alone, the FDG uptakes in WT1-vaccinated skin might reflect the degree of immune response. These results suggest that PET-CT might be a good tool for prediction of anti-tumor immune response induced by WT1 vaccine therapy. Larger scale prospective studies therefore seem to be warranted.

Abstract
Abstract
Background
There has been growing evidence that the glucose fluctuation is an important contributing factor to the development of coronary artery disease. However, whether large glucose fluctuation, especially hypoglycemia, may be associated with acute myocardial infarction (AMI) remains largely unknown.
Aim
As new continuous glucose monitoring (CGM) has recently become available to evaluate glucose fluctuation from immediately after an emergency visit, this study sought to investigate glucose fluctuation and the occurrence of hypoglycemia in patients with AMI.
Methods
In this prospective study, 93 consecutive patients with AMI from April 2017 to November 2018 were enrolled. Subcutaneous interstitial glucose levels were monitored from emergency room to discharge using the CGM System. Based on the CGM data, 24-h mean glucose levels, the time in hyperglycemia and hypoglycemia and the occurrence of hypoglycemia, defined as less than 70 mg/dL, were measured, and the mean amplitude of glycemic excursions (MAGE) were calculated.
Results
The majority of patients [n=57, 61% (non-DM)] did not have diabetes and 36 patients had diabetes (DM). The occurrence of hypoglycemia within 24 hours after admission was observed in 49 patients [DM: n=11 (30.6%), non-DM: n=38 (66.7%)]. MAGE within 24 hours after admission were 100±47 in DM patients and 67±20 in non-DM patients. The mean time in hypoglycemia within 24 hours after admission was 148 minutes [DM: 100±260 minutes, non-DM: 178±287 minutes]. The occurrence of hypoglycemia during a hospital stay (mean 11.5 days) was detected in 76 patients [DM: n=28 (77.8%), non-DM: n=48 (84.2%)].
Representative case of hypoglycemia
Conclusion
Not only in DM patients but also in non-DM patients with AMI, large glucose fluctuation and high incidence of hypoglycemia were observed using new CGM system. Further investigations should address the rationale for the early detection and control of glucose fluctuation for AMI patients.

Abstract
BACKGROUND Although evidence for the short- to medium-term efficacy of adalimumab in ulcerative colitis (UC) patients is emerging, there are a limited number of reports on the long-term efficacy of adalimumab. This study was to understand baseline demographic features, which potentially could be risk factors for relapse or colectomy following induction of remission by adalimumab in UC patients. Additionally, factors affecting long-term outcomes were to be identified. METHODS Twenty-one patients with UC who had been treated with adalimumab were reviewed retrospectively. Comparative analyses were undertaken by factoring steroid withdrawal versus non-withdrawal, long-term remission versus relapse following remission, and requiring surgical intervention for UC versus surgery-free. RESULTS Adalimumab treatment was associated with steroid tapering in steroid-dependent cases in the long term. Of the 14 patients in whom clinical remission was achieved, the cumulative nonrelapse survival rate at 350 weeks was 43.8% and the cumulative nonoperative survival rate was 85.7%. Risk factors for surgery included intolerance to salicylates (p = 0.005) and past treatment with tacrolimus (p = 0.023). CONCLUSIONS Adalimumab treatment was associated with long-term efficacy in patients with mild UC - patients achieved a high cumulative nonoperative survival rate over a long period of time, beyond 6 years.

Abstract
BACKGROUND Although Th2 cells are well known to play important roles in allergic diseases including allergic rhinitis (AR), the factors that induce and sustain the pathogenesis of AR remain unclear. The recent development of sublingual immunotherapy (SLIT) is expected to allow changes to the underlying pathogenesis of AR. However, which Th2 cell subsets are important in house dust mite-induced AR (HDM-AR), the influence of SLIT on the pathogenic Th2 cells, and the association of Th2 cell subsets with SLIT efficacy have not been clarified. METHODS The cytokine production and frequency of HDM-reactive T-cell subsets in peripheral blood mononuclear cells (PBMCs) were evaluated using flow cytometry in 89 HDM-AR patients (placebo [n = 43] and HDM 300 IR [n = 46]) who participated in a placebo-controlled study of SLIT with HDM tablets. All patients provided samples both before treatment as a baseline and at the end of the 52-week study. The PBMCs were stained with CellTrace™ Violet (CTV) before culture with HDM extract, and HDM-reactive T cells were detected as the proliferated cells with diminished CTV. RESULTS HDM-reactive IL-5+ IL-13+ CD27- CD161+ CD4+ cells and ST2+ CD45RO+ CD4+ cells were observed in the peripheral blood from each patient with HDM-AR; these cells significantly decreased after SLIT in the group treated with active tablets. HDM-reactive ST2+ CD45RO+ CD4+ cells were significantly lower in active-responders. CONCLUSION Allergen-reactive ST2+ CD45RO+ CD4+ cells or those combined with IL-5+ IL-13+ CD27- CD161+ CD4+ cells may be useful as markers indicating the successful treatment of SLIT. These cells may play a crucial role in the pathogenesis of AR as pathogenic memory Th2 cells.

Abstract
Objectives Adsorptive granulomonocytapheresis (GMA) with the Adacolumn has been introduced as a non-pharmacologic treatment for ulcerative colitis (UC). However, a subset of patients who might respond well to GMA needs to be targeted. This study was conducted at three IBD centers to determine factors affecting the efficacy of GMA in patients with moderately-to-severely active UC. Methods From January 2008 to December 2017, a total of 894 active episodes (first attack or relapse) in 593 patients were treated with GMA. Clinical remission was defined as normal stool frequency and no rectal bleeding. Multiple clinical and laboratory parameters at entry were considered for efficacy assessment. Results Clinical remission was achieved during 422 (47%) of the 894 treatment cases. In the multivariate analysis, predictors for favorable response to GMA were age ≤60 years, UC duration <1 year, Mayo endoscopic subscore 2 (vs. 3), steroid naïve UC, and biologic naïve UC. Clinical remission rate was 70% in patients with four of the five factors, 52% in patients with three factors, 46% in patients with two factors, 39% in patients with one factor, and 18% in patients with none of these factors. Overall, the clinical remission rate was significantly higher in patients with a greater number of the five predictors (P < 0.0001). Conclusions GMA appeared to be effective in steroid naïve and biologic naïve patients with short duration of UC. Elderly patients (>60 years) and those with severe endoscopic activity did not respond well to GMA. Additional, well designed, prospective, controlled trials should strengthen our findings.

Abstract
Peripheral neuropathy (PN) caused by bortezomib is an important complication of multiple myeloma. Subcutaneous injection of bortezomib reduced PN, but 24% of cases were grade 2 PN and 6% of cases were grade 3 PN. PN higher than grade 2 was not resolved by subcutaneous injection. PN higher than grade 3 has serious dose limiting toxicity and is the cause of discontinuing bortezomib treatment. Lafutidine is an H2-blocker with gastroprotective activity and is thought to function by increasing mucosal blood flow via capsaicin sensitive neurons. The same activity of lafutidine is considered to improve glossodynia and taxane induced PN. We hypothesized that lafutidine prevents or improves PN that is caused by bortezomib. In the current study, bortezomib was administered in the usual manner (intravenous administration of bortezomib 1.3 mg/m2, twice a week for 2 weeks, followed by 1 week without treatment) for up to four cycles to compare our data with other studies. Lafutidine was administered orally at a dose of 10 mg twice daily. In our eight evaluated cases, the total occurrence of PN was four out of eight patients (50%). There were only grade 1 PN (4 out of 8) cases, and no cases higher than grade 2. We conclude that (1) the total occurrence of PN was not improved, (2) there was no PN after the first course, (3) there were only grade 1 cases and there were no cases higher than grade 2, and (4) no cases discontinued bortezomib treatment because of PN. This is the first report showing that lafutidine is useful for the amelioration of bortezomib induced PN.

Abstract
The aim of this study was to determine the loading capacity of a trotting Taishuh pony by gait analysis using a motion analysis system. Seven Taishuh Ponies (5 mares and 2 geldings) and their rider were fitted with a marker (70 mm in diameter placed on their chest) and recorded by 2 high-resolution digital DVD cameras (at a sampling frequency of 60 Hz) as they were trotting along a straight course. Each horse performed 7 tests: 1 test with a loaded weight of 70 kg, 5 tests with random loaded weights between 80 kg and 120 kg, and a final test with a loaded weight of 70 kg again. Three-dimensional movements of each marker were analyzed using motion capture system. The time series of the vertical displacements of the marker was subjected to spectrum analysis by the maximum entropy method, and the autocorrelation coefficient was calculated. The first 2 peaks of the autocorrelation were defined as symmetry and regularity of the gait, and the sum of symmetry and regularity was defined as stability. The cross-spectrum analysis (Blackman-Tukey method) also was performed to analyze the time lag and cross-correlation coefficient between the time series of both pony and rider. Among ponies, symmetry in the 120 kg test (0.54) was significantly lower than that in the first 70 kg test (0.75, P < 0.05) and stabilities in the 100 kg (1.17) and 120 kg (1.17) tests were significantly less than that in the first 70 kg (1.46, P < 0.05). Regarding the rider, there were no significant differences in symmetry, regularity, and stability between loaded weights. The time lag between the time series of horse and rider in the 120 kg test (47.6 ms) was significantly greater than that in the first 70 kg (14.3 ms, P < 0.05) test. These results suggests that the maximum permissible load weight of the Taishuh pony trotting at 3.0 m/s over a short distance was less than 100 kg, which is 43% of the BW.

Abstract
INTRODUCTION Preeclampsia is characterized as an increase in vascular tone due to the disorder of endothelial cell function. It was found that action of nitric oxide (NO) derived from endothelial cell might be decreasing in preeclamptic women. OBJECTIVES In the present study, we investigated whether or not the supplementation of L-arginine (LARG, NO synthase substrate) and folic acid (FA) might improve the reduced action of NO seen in preeclampsia. METHODS Change in brachial artery diameter by hyperemia (%FMD) was measured to evaluate the endothelial function using ultrasound. Twelve of 25 normal pregnant women seen with reduced %FMD (<110) at less than 16weeks of gestation were given the supplementation of FA 0.8mg+LARG1g/day throughout pregnancy. The concentrations of FA+LARG in erythrocyte, and cGMP (a second messenger of NO) in serum were measured. The informed consent was obtained from each patient. This investigation was approved by the Ethics Committee of Nagoya City East and West Medical Center. RESULTS Reduced % FMD was seen in 25 pregnant women. One of 12 pregnant women in the supplementation group developed mild, late onset preeclampsia, while 8 of 13 pregnant women in no supplement group developed onset preeclampsia (4 cases were severe). Following the supplementation, %FMD had been increasing as well as the concentrations of FA and LARG in erythrocyte, while the concentration of cGMP in serum had not changed. CONCLUSION The supplementation of FA+LARG might prevent preeclampsia due to improvement of the reduced endothelial function in high risk pregnant women of preeclampsia.

Abstract
INTRODUCTION It was found that eclampsia might be caused by vasogenic edema as a result of breaking autoregulation of cerebral blood flow. The finding of PRES (posterior reversible encephalopathy syndrome) was seen on MRI (T2 FLAIR) in eclamptic women. PRES was also seen in women complicated by severe hypertension. Therefore, severity of hypertension might depend on the onset of eclampsia in pregnant women. However, it remains to be unclear with other factors except severity. OBJECTIVES In the present study, we estimated the pathophysiological mechanisms focusing on changes of blood pressure in preeclamptic women. METHODS From May to December 2011, 5 eclamptic women were present in Nagoya City West Medical center (795 pregnant women, including 22 preeclamptic women). Four of preeclamptic women developed eclampsia. We recorded changing blood pressure and analyzed them for 4 days (before and after 2 days). RESULTS Three were severe hypertension (more than 160/110mmHg) before 2days. Just before, all showed wide-oscillation of blood pressure (more than 30/15mmHg). One was severe preeclampsia in 37weeks of gestation. After cesarean section, blood pressure was decreasing (100/50mmHg), due to blood loss. Taking blood transfusion, blood pressure subsequently increased and disease occurred. Double product, which means a working index of heart function was low and was in turn low after it. Furthermore, shock index, which means a blood volume was upset. CONCLUSION From these results, it was suggested that a wide-difference of blood pressure might induce elampsia in women complicated by preeclampsia.

Abstract
Whether galectin-9 plays a role in inflammatory responses remains elusive. The present study was designed to determine the role of intracellular galectin-9 in activation of inflammatory cytokine genes in human monocytes. Galectin-9 expression vector pBKCMV3-G9 was transiently co-transfected into THP-1 monocytic cells along with luciferase reporters carrying gene promoters of IL-1alpha (IL1A), IL-1beta (IL1B) and IFNgamma. Transient transfection studies showed that galectin-9 over-expression activated all three gene promoters, suggesting that intracellular galectin-9 induces inflammatory cytokine genes in monocytes. Galectin-9 over-expression also activated NF-IL6 (C/EBP beta) and AP-1, but not NF-kappaB. In contrast, extracellular galectin-9 is not involved in regulation of inflammatory cytokines. Immunoprecipitation/Western blotting, using anti-galectin-9 Ab and anti-NF-IL6 Ab, showed physical association of intracellular galectin-9 with NF-IL6. RT-PCR confirmed that galectin-9 over-expression increased IL-1alpha and IL-1beta mRNA levels in THP-1 cells. The interaction of galectin-9 with NF-IL6 was enhanced following LPS treatment in THP-1 cells. Intracellular galectin-9 synergized with LPS to activate NF-IL6. Nuclear translocation of galectin-9 was also observed in THP-1 cells treated with LPS. Our results indicate that galectin-9 is a LPS-responsive factor, and further demonstrate that intracellular galectin-9 transactivates inflammatory cytokine genes in monocytes through direct physical interaction with NF-IL6.

Abstract
The element-specific electronic structure of the organic semiconductor aluminum tris-8-hydroxyquinoline (Alq(3)) has been studied using a combination of resonant x-ray emission spectroscopy, x-ray photoelectron spectroscopy, x-ray absorption spectroscopy, and density functional theory (DFT) calculations. Resonant and nonresonant x-ray emission spectroscopy were used to measure directly the carbon, nitrogen and oxygen 2p partial densities of states in Alq(3), and good agreement was found with the results of DFT calculations. Furthermore, resonant x-ray emission at the carbon K-edge is shown to be able to measure the partial density of states associated with individual C sites. Finally, comparison of previous x-ray emission studies and the present data reveal the presence of clear photon-induced damage in the former.

Abstract
OBJECTIVE Constitutive activation of nuclear factor (NF)-kappaB is a common feature of human T-cell leukemia virus type I (HTLV-I)-transformed T cells. Inhibition of NF-kappaB activity reduces cell growth and induces apoptosis of HTLV-I-transformed T cells, suggesting a central role of NF-kappaB in their proliferation and survival. In this study, we investigated whether MyD88, an adaptor protein of Toll-like receptor (TLR) signaling, contributes to constitutive NF-kappaB activation in HTLV-I-transformed T cells. MATERIALS AND METHODS Activation status of MyD88 and interleukin (IL)-1R-associated kinase 1 (IRAK1) in HTLV-I-transformed human T cells, MT2, MT4, and HUT102 was examined by using Western blot and immunoprecipitation. TLR expression was evaluated with reverse transcription polymerase chain reaction. An expression vector encoding a dominant negative MyD88 with a deletion of its death domain (MyD88dn) was transfected into MT2 cells to evaluate roles of MyD88 in spontaneous activation of cytokine gene promoters and transcription factors, proliferation, and apoptosis in HTLV-I-transformed T cells. RESULTS Constitutive association of MyD88 with IRAK1 was observed in all three of HTLV-I-transformed T cells, but not in HTLV-I-negative T cells, such as Jurkat, HUT78, and MOLT4. MT2 cells showed expression of TLR-1, -6, and -10 mRNAs. Constitutive activation of NF-kappaB and NF-IL-6 and cytokine gene promoters, such as IL-1alpha, interferon-gamma, and tumor necrosis factor-alpha in MT2 cells was inhibited by MyD88dn expression. MyD88dn reduced proliferation and induced apoptosis of MT2 cells. HTLV-I Tax enhanced TLR expression and synergistically activated NF-kappaB with wild-type MyD88. CONCLUSION Our results show a novel pathway in NF-kappaB activation in HTLV-I-transformed T cells and further demonstrate a critical role of MyD88 in their dysregulated gene activation, survival, and proliferation.

Abstract
Activation of c-jun N-terminal kinase (JNK) through c-kit-mediated phosphatidylinositol 3 (PI3) and Src kinase pathways plays an important role in cell proliferation and survival in mast cells. Gain-of-function mutations in c-kit are found in several human neoplasms. Constitutive activation of c-kit has been observed in human mastocytosis and gastrointestinal stromal tumor. In the present study, we demonstrate that an anthrapyrazole SP600125, a reversible ATP-competitive inhibitor of JNK inhibits proliferation of human HMC-1 showed constitutive activation of JNK/c-Jun, and the inhibitory effect of SP600125 on cell proliferation was associated with cell cycle arrest at the G1 phase and apoptosis accompanied by the cleavage of caspase-3 and PARP. Caspase-3 inhibitor Z-DEVD-FMK almost completely inhibited SP600125-induced apoptosis of HMC-1 cells. In contrast, caspase-9 inhibitor Z-LEHD-FMK failed to block SP600125-induced apoptosis. Following Sp600125 treatment, down-regulation of cyclin D3 protein expression, but not p53 was also observed. Thus, JNK/c-Jun is essential for proliferation and survival of HMC-1 cells. The results obtained from the present study suggest the possibility that JNK/c-Jun may be a therapeutic target in diseases associated with mutations in the catalytic domain of c-kit.

Abstract
Heartstring is a useful device. However, the device failure at the time of loading the seal into the delivery device is a troublesome issue. To avoid this problem, we invent a new method using 2 tourniquets made of 5 mm-wide woven Teflon tapes and plastic tubes. Using our method, the loading procedure became easier and more reliable.

Abstract
A 57-year-old woman with chronic myeloid leukemia showing severe basophilia (WBC 17.1 X 10(9)/L, basophils 23%) was treated with 400mg imatinib in June 2003. A high basophil count (WBC 10.6 X 10(9)/L, basophils 31%) was still observed after 1 week of therapy. After 9 days of therapy, she developed generalized pruritic skin erythema, chills and high fever. After terminating imatinib treatment, prednisolone therapy was initiated. The rash quickly disappeared. Four days after withdrawal of imatinib, leukocyte count was 13.0 X 10(9)/L with 3% of basophils, suggesting the possibility that rapid decrease in basophils following imatinib therapy may induce severe cutaneous reactions.

Abstract
BACKGROUND AND OBJECTIVES Sodium bicarbonate is the most physiological alkalinizing agent. The effect of a new bicarbonated Ringer's solution (BRS) containing Mg2+, on metabolic acidosis and serum magnesium abnormality were evaluated and compared with those of acetated Ringer's (ARS), lactated Ringer's (LRS) and Ringer's (RS) solutions in an experimental haemorrhagic shock model with dogs. METHODS Animals were randomly divided into six groups (n = 6 in each group), a sham-operated group, an operated group without infusion, and 4 operated groups with infusion (BRS, ARS, LRS and RS groups). Each RS was intravenously administered at 60 mL kg(-1) h(-1) for 1.5 h. Arterial blood gases, plasma electrolytes and cardiovascular parameters were analysed. RESULTS BRS significantly improved blood base excess values, which were decreased by blood-letting, faster and more markedly than did LRS and RS (BRS--6.3 +/- 0.5 mEq L(-1); LRS--9.2 +/- 1.1 mEq L(-1); RS--12.4 +/- 1.0 mEq L(-1) at the end of infusion). The alkalinizing effect of BRS tended to be better than that of ARS but not significantly so. The serum Mg2+ concentration was well-maintained by BRS as compared to other RS (BRS 1.5 +/- 0.0 mgdL(-1); ARS 1.2 +/- 0.0mgdL(-1); LRS 1.1 +/- 0.0mgdL(-1); RS 1.3 +/- 0.1 mgdL(-1), at the end of infusion). CONCLUSIONS These results suggest that BRS is a suitable perioperative solution for metabolic acidosis and serum electrolyte balance among RS tested.

BACKGROUND AND OBJECTIVE The effects of bicarbonated Ringer's solution were evaluated and compared with those of acetated Ringer's, lactated Ringer's and Ringer's solutions in partially hepatectomized rabbits. METHOD Animals were randomly divided into six groups (n = 6 in each group): a sham-operated group, an operated group without infusion, and four operated groups with infusions of each of the four Ringer's solutions. Each Ringer's solution was intravenously administered at 40 mL kg(-1) h(-1) for 1.5 h. Arterial blood gases, plasma magnesium concentrations and cardiovascular parameters were analysed. RESULTS The partial hepatectomy-induced decrement of base excess was inhibited by bicarbonated Ringer's solution more remarkably than by either lactated or plain solutions (P < 0.01). The alkalinizing effect of bicarbonated Ringer's solution tended to be more marked than that of the acetated solution but not significantly so. Plasma magnesium concentrations were well maintained by bicarbonated solution as compared to the other solutions (P < 0.01). CONCLUSIONS These results suggest that bicarbonated Ringer's solution is the most suitable perioperative solution for metabolic acidosis and plasma electrolyte balance among the Ringer's solutions tested.

Abstract
Wilson disease (WD) is an autosomal recessive disorder of copper transport, resulting in copper accumulation and toxicity to the liver and brain. There is no evidence that the WD patient's immune system attacks copper accumulated hepatocytes. Here we describe that the frequency and absolute number of Valpha24+Vbeta11+ natural killer T (NKT) cells were significantly increased in 3 cases of WD, whereas those of CD3+CD161+ NKT cells were within the normal range. Patients no. 1 and 2 had a presymptomatic form of WD. Their tissue specimens showed pathological changes of mild degeneration of hepatocytes with a few infiltrating mononuclear cells and a low degree of fatty change. Patient no. 3 displayed fulminant hepatitis with Coombs-negative haemolytic anaemia. The tissue specimens of patient no. 3 showed macronodular cirrhosis with thick fibrosis, inflammatory infiltrates and spotty necrosis. Human Valpha24+Vbeta11+ NKT cells are almost equal to CD1d-restricted NKT cells. Therefore we investigated CD1d-restricted NKT cells in the LEC rat as an animal model of WD. In LEC rats before hepatitis onset, the number and phenotype of liver NKT cells were normal. At about 4 months of age all LEC rats developed acute hepatitis accompanied by acute jaundice, and CD161high NKT cells developed in their livers. CD161highalphabetaTCRbright NKT cells developed in some of them. Their hepatitis was severe. CD161highalphabetaTCRbright NKT cells expressed an invariant rat Valpha14-Jalpha281 chain, which is CD1d-restricted. Furthermore, liver lymphocytes in the acute jaundiced LEC rats with CD161highalphabetaTCRbright NKT cells had significant and CD1d-specific cytotoxic activity.

Abstract
A 71-year-old woman was admitted in December 2002 because of lymphadenopathy, hepatosplenomegaly and pleural effusion. She had severe anemia with hemoglobin 5.9 g/dl and a reticulocyte count of 1% per hundred. Direct/indirect Coombs tests and anti-double stranded DNA antibody were positive, her serum CH50 level was reduced and an increase in serum LDH isoenzyme 3 was observed. Bone marrow aspiration showed an almost total absence of erythroblasts and no pathological cell proliferation. The diagnosis of angioimmunoblastic T-cell lymphoma (AILT) was made based on the lymph node histological findings. Proliferation of arborizing small vessels with hyperplastic endothelium and infiltration of atypical T-lymphocytes were observed. After combination chemotherapy (THP-COP), remission was achieved in both the pure red cell aplasia (PRCA) and AILT. Remission was also accompanied by normalization of the Coombs tests, suggesting that autoimmune mechanisms in AILT may contribute to the development of PRCA.

Abstract
Contemporary mushroom factories are places where there is a substantial risk of the occurrence of respiratory allergy. The aims of this investigation were to estimate its causative agents and to evaluate the contribution of innate immune response in mushroom workers who cultivate Hypsizigus marmoreus (Bunashimeji). Cross-sectional and follow-up studies were performed in the factory. We investigated CD1b, CD3, CD4, CD8, CD14, CD45RO, CD62L and CD161 expression in peripheral blood mononuclear cells (PBMC) by flow cytometry, and serum levels of interleukin (IL-2), IL-4, granulocyte-macrophage colony stimulating factor (GM-CSF), IL-13 and interferon (IFN)-gamma by enzyme-linked immunosorbent assay (ELISA). Co-culture experiments of PBMC with spore extracts were also performed. Percentages of CD1b+ monocytes, natural killer (NK), NK T and CD4+ T cells were increased in the workers compared with controls. Increases in Th2 type cells, Th2/Th1 ratio and serum IL-13 and decreased IFN-gamma were detected, indicating a Th2-biased status of the workers. The follow-up study showed that monocytes and NK cells increased soon after employment while CD4+ T, Th2 and NK T cells increased gradually as employment time lengthened. Serum precipitating antibody to the mushroom antigen could be detected at a later stage. Co-cultivation of PBMC with the spore extracts induced much higher CD1b expression, and suppressed secretion of Th1 cytokine in culture supernatants. These results indicate that the mushroom antigen contains highly immunogenic substances which stimulate PBMC into a Th2-biased in vivo status, and innate immune cells might also play a critical role in developing respiratory allergy in mushroom workers.

Abstract
As total arterial revascularization in coronary artery bypass grafting (CABG) has been recommended, a sequential bypass technique using arterial grafts has been induced. We evaluate whether a sequential bypass graft can be functioned or not by using a simple simulation model for coronary circulation analogous to the electrical circuit based on Ohm law. The ratio of flow between graft and native coronary artery was determined by the severity of stenosis in the bypassed vessels and the graft diameter. In selection for sequential bypass technique, these factors should be taken into consideration.

Abstract
AIMS The 'metaplastic' polyp of the colorectum, a synonym for the hyperplastic polyp, was named based only on features of the crypt epithelium. It is considered non-neoplastic, but the precise cellular differentiation status remains to be proven. METHODS AND RESULTS Forty-eight hyperplastic polyps, 12 serrated adenomas, 45 tubular adenomas and five juvenile polyps were studied for their phenotypic expression using gastric (foveolar or pyloric gland cell), small intestinal (goblet cell), and colonic (goblet cell) cellular markers by immunohistochemical and mucin histochemical techniques. Gastric foveolar cell-type differentiation was significantly expressed in hyperplastic polyps, while colonic differentiation was also consistently preserved. Neither gastric pyloric-type nor small intestinal differentiation was observed. The same cell differentiation status as hyperplastic polyps was observed in serrated adenomas but not in tubular adenomas or juvenile polyps. CONCLUSIONS A large proportion of hyperplastic polyps are composed of hybrid epithelium, with bidirectional differentiation to both gastric foveolar and colonic epithelial cells in the same crypt. Therefore hyperplastic polyps might be interpreted as the outcome of abnormal cell differentiation of stem cells. The same phenotypic expression suggests that hyperplastic polyps and serrated adenomas share the same cell lineage.

Abstract
Identification of factors influencing success of Helicobacter pylori (HP) eradication is important for clinical practice. We have prospectively conducted an HP eradication study in the Aichi Cancer Center with a total of 142 patients available for analysis. The overall success rate was 61.3% (95% confidence interval 52.7-69.3%). Smoking during the medication for eradication significantly decreased the success rate (42.9%), whereas smoking cessation during the treatment was associated with a similar rate as for non-smokers (66.7%). We also examined links between an eradication outcome and polymorphisms of Le, Se, IL1A, IL1B, IL1RN and MPO genes, but with one exception none showed any association. The non-functional le allele of Le polymorphisms, leading to decreased expression of Le(b) antigen to which HP attaches with adhesin, showed a beneficial effect for success. Although further clarification is necessary, our study indicated that smoking cessation and Le gene polymorphisms may affect the success rate of HP eradication.

Abstract
Various types of assist devices have been developed for severe heart failures. Among them, intra-aortic balloon pumping (IABP) has achieved popularity, mainly in the treatment of patients with either severe cardiac infarction or low cardiac output syndrome (LOS) after open-heart surgery. However, IABP has a limitation in that although it acts as a pressure support, it cannot directly support flow volume. In cases of severe pump failure, stronger pump support would be required. However, there is a limit in the clinical use of temporary mechanical support using a pump because of the costs of the expensive equipment. With this in mind, we came up with a new idea in which the motion of a balloon in IABP system is converted into a power source for creating a one-way stream. In order to realize our idea, we made a J-shaped sample model of pulsating chamber incorporating two ball valves. In the hydrodynamic experiment using our new device, flows over 2500 ml/min (Max. 3475 ml/min) were obtained. The percent changes in parameters such as TTI, DPTI and bypass flows obtained by the experiment of left ventricular bypass have demonstrated that our assist system is effective for reducing cardiac work.

Abstract
Exposure to mushroom spores may cause many respiratory allergic diseases, however, there has been no serial study in a mushroom factory to address this problem. The aim of this study was to investigate the serial changes in respiratory allergy and the incidence of hypersensitivity pneumonitis (HP) in mushroom workers. A 3-year follow-up study, beginning in June 1996, was conducted in a newly operating mushroom factory in which one kind of mushroom is produced: Hypsizigus marmoreus (Bunashimeji). Allergic symptoms, chest roentgenogram, serum precipitins to the spores and soluble adhesion molecules in sera were evaluated once a year in 60 workers and 20 controls. Three out of the 60 subjects were diagnosed as having HP caused by inhalation ofthe mushroom spore and they were therefore excluded from this study, and the 57 non-HP subjects were evaluated. In this study 24 workers quit because of intolerable cough, runny nose, wheezing, sputum, fever elevation and/or shortness of breath at their place of work. During each year of this study as many as 70-80% of employees suffered some ofthe above symptoms, cough being the most frequent, and positive rate of serum precipitins to the spore revealed 30% in 1996, 93% in 1997 and 94% in 1998. From the June 1996 examination until the following May, serum soluble intercellular adhesion molecule-1 levels of the 15 workers who quit during that period were significantly higher than those in the 42 workers still employed in 1997 (P < 0.05). Workers in Bunashimeji mushroom factories might be at critical risk of developing respiratory allergy. In our 3-year study over 90% workers were sensitized to the spore, 40% quit because of the symptoms and 5% developed HP. It was suggested that workers should be counselled about the risk of mushroom allergy and precautionary measures should be taken to prevent its occurrence.

Abstract
Although improving energy metabolism in ischemic brain has been accepted for the treatment of cerebrovascular diseases, administration of glucose, as an energy substrate, would aggravate ischemic brain damage via activating anaerobic glycolysis, which leads to lactate accumulation. Beta-hydroxybutyrate (BHB) is one of the ketone bodies that can be utilized as an energy source during starvation. The purpose of our study was to define the protective effects of BHB on brain damage induced by hypoxia, anoxia and ischemia. The isotonic solution of BHB administered 30 min before the induction of ischemia at doses over 50 mg x kg(-1) x h(-1) showed remarkable protective effects against hypoxia and anoxia. BHB administered immediately after a bilateral carotid artery ligation at a dose of 30 mg x kg(-1) x h(-1) significantly suppressed the elevation of cerebral water and sodium contents as well as maintaining high ATP and low lactate levels. In contrast, glycerin, a hypertonic agent, substantially reduced the water content but did not show any significant effect on other parameters. We demonstrated that BHB, unlike glycerin, when used as an energy substrate in ischemic brain, has protective effects on cerebral hypoxia, anoxia and ischemia-induced metabolic change.

Abstract
Expression systems of human and silkworm lysozymes were constructed using the methylotrophic yeast Pichia pastoris as a host. The leader sequence and its prepro peptide of alpha-factor (a peptide pheromone derived from yeast) and the native signal sequences of these lysozymes, were used as secretion signals. When the alpha-factor leader is used as the signal sequence, human lysozyme is secreted at a much higher level than is silkworm lysozyme. On the other hand, silkworm lysozyme, when its native signal is used, is secreted more efficiently than human lysozyme. Therefore, we expected that human lysozyme cDNA with a silkworm native signal would be secreted more efficiently than human lysozyme with its native signal. However, its level of expression was not increased. This result indicates that the native signal of silkworm lysozyme does not promote the secretion of the lysozyme, but rather alpha-factor leader inhibits the secretion. Silkworm lysozyme with the alpha-factor leader is so unstable that it could be easily attacked by some proteases and our findings suggest that the level of expression of heterologous protein with signal peptides and its stability are greatly affected by the selection of the appropriate secretion signal sequence.

Abstract
We previously showed that the cell surface-expressed Mr 70,000 heat shock cognate (hsc70, a constitutively expressed member of the hsp70 family) protein-like molecule (#067 molecule) interacts with rat CD3+, CD4-, CD8-, T-cell receptor (TCR)alphabeta-, natural killer recetor-P1- T cells. This 70hsc-like molecule was also suggested to present cellular peptide antigens to these T cells. In the present study, we identified the genetic structure of the TCR by establishing T-cell hybridomas between these T cells and mouse BW5147 cells. Our data indicated that these T cells preferentially used TCRs with the Vdelta6 family. Analysis of the nucleotide sequence of the CDR3 junctional portion showed that there are substantial diversities, with insertion of seven to nine amino acid residues. These data provide indirect evidences for our hypothesis that an hsc70-like molecule could be presented together with cellular peptide antigens to particular T cells with TCR gammadelta chains. Since the expression of this hsc70-like #067 antigen on the cell surface is usually induced along with cell transformation by activated oncogenes, T cells with the TCR Vdelta6 family are likely to contribute to host resistance to tumor cells.

Abstract
beta-Catenin, a multifunctional protein related to the adherens junction and to signal transduction, is a key molecule of cell proliferation, and it is central to epithelial architecture, regulating the polarity of cells and tissues. beta-Catenin stabilization may play a key role in epidermal signaling leading to hair development, and its aberrant activation may be implicated in formation of hair tumors. Several investigators have shown that pilomatricomas are frequently associated with beta-catenin mutation. In this study, we confirmed beta-catenin gene (CTNNB1) mutation in human pilomatricomas (100% frequency) from which adequate DNA could be obtained for gene analysis. A novel mutation, D32N, was found in one case of pilomatricoma. A preliminary immunohistological study revealed prominent beta-catenin staining in basophilic cells of pilomatricomas, especially in nuclei. Benign tumors which were considered to be derived from hair matrix or hair follicles, and other benign skin tumors, were also investigated. beta-Catenin mutations were not detected in any of the these tumors. These results seem to indicate that hair matrix cells are key players in hair development. Investigation into gene abnormalities of hair-follicle tumors may elucidate the cause of their neoplastic transformation, and may provide a suggestion for the mechanism of hair development.

Abstract
Our previous study revealed that a polymorphism of the interleukin (IL) 1B gene, encoding the pro-inflammatory cytokine IL-1 beta, influenced the prevalence of persistent Helicobacter pylori (HP) infection. In this paper, a polymorphism of another inflammation-related enzyme, myeloperoxidase (MPO), was examined with respect to association with the HP infection. The polymorphism is due to a G-to-A transition at - 463 in the promoter region of MPO. The G allele is the wild type with normal expression, while the A allele is a low expression allele. The subjects were 241 non-cancer outpatients (118 males and 123 females) aged 39 to 69 who participated in an HP eradication program at Aichi Cancer Center Hospital. High-molecular weight Campylobacter-Associated-Protein (HM-CAP) ELISA (Enteric Products Ins., Westbury, NY) was used for the identification of HP-infected participants. The frequency was 79.7% (192 / 241) for the GG genotype, 19.5% (47 / 241) for the GA genotype, and 0.8% (2 / 241) for the AA genotype. The sex-age-adjusted odds ratio (OR) relative to GG was 0.69 (95% confidence interval (CI), 0.35 -- 1.35) for individuals with the A allele, but among male participants the OR was 0.31 (0.11 -- 0.84). Subgroup analysis revealed significantly reduced ORs with the GA / AA genotypes for current smokers (0.19, 0.04 -- 0.96), and for those who were occasional / no milk drinkers (0.25, 0.09 -- 0.72). These findings are consistent with the results for IL-1B in our earlier study, suggesting that inflammatory responses in the gastric mucosa may influence persistent HP infection, and that smoking and milk intake may be effect-modifiers.

Abstract
The cholesteryl ester, foam cell-enriched vulnerable plaque is a principle pharmacological target for reducing athero-thrombosis. Acyl CoA:cholesterol Acyl Transferase (ACAT) catalyzes the esterification of free cholesterol in intestine, liver, adrenal and macrophages, leading in the latter cells to intracellular cholesteryl ester accumulation and foam cell formation in the arterial intima. Previous studies suggested the existence of several isoforms of ACAT with different tissue distribution and this has largely been confirmed by molecular cloning of ACAT-1 and ACAT-2. We developed a series of ACAT inhibitors that preferentially inhibited macrophage ACAT relative to hepatic or intestinal ACAT based on in vitro assays and ex vivo bioavailability studies. Four of these compounds were tested in three models of atherosclerosis at oral doses shown to give sufficient bioavailable monocyte/macrophage ACAT inhibitory activity. In fat-fed C57BL/6 mice, chow fed apo E-/- mice and KHC rabbits, the various ACAT inhibitors had either no effect or increased indices of atherosclerotic foam cell formation. Direct and indirect measurements suggest that the increase in plaque formation may have been related to inhibition of macrophage ACAT possibly leading to cytotoxic effects due to augmented free cholesterol. These results suggest that pharmacological inhibition of macrophage ACAT may not reduce, but actually aggravate, foam cell formation and progression.
