Abstract
BACKGROUND Although the involvement of intestinal microbiota in innate immunity has been reported recently, the pathogenicity of autoimmune pancreatitis (AIP) remains unclear. This study aimed to investigate whether probiotics ameliorate inflammation in AIP through interactions with innate immunity. METHODS The AIP mouse model was generated by intraperitoneal administration of E. coli to C56BL/6 female mice. Alterations in the intestinal microbiota in the AIP group were evaluated using high-throughput sequencing. Peritoneal macrophages (PMs) were collected and cocultured in vitro with Lactobacillus gasseri (LG) or ligands of toll-like receptors (TLRs). LG was administered intraperitoneally to AIP model mice, and pancreatitis activity was evaluated to examine the ameliorative effects of LG. RESULTS In the AIP model mice, inflammation was significantly induced in the pancreas, and the intestinal microbiota was altered with decreased LG. Antimicrobial treatment suppressed pancreatitis. In vitro, E. coli stimulation increased inflammatory cytokine expression, which was significantly decreased when the LG or TLR7 ligand was cocultured with PMs. Intraperitoneal administration of LG to AIP model mice significantly suppressed pancreatitis. CONCLUSION The mouse model demonstrated the involvement of intestinal microbiota in pancreatitis, and LG administration suppressed pancreatitis, possibly through TLR7 signaling in PMs. LG may be a helpful probiotic for treating AIP.

Abstract
We herein present a unique and extremely rare fulminant case of Edwardsiella tarda infection-related necrotizing fasciitis. The patient had alcoholic cirrhosis and preferred to consume raw fish. He experienced painful swelling of the right forearm one day after he got a minor injury when falling from the ladder, and visited our hospital. His accompanied symptoms were diarrhea and general fatigue. His consciousness got deteriorated after the admission. The lesion of the right forearm had spread and the color had deteriorated with epidermolysis in a few hours. Necrotizing soft-tissue infection was suspected, and emergency debridement of the swollen forearm was performed 4 hours after the admission. However, unfortunately, he died of sepsis approximately 5 hours later. Histological examination of the biopsy specimen revealed features consistent with those of necrotizing fasciitis. The bacterial cultures of blood and the wound identified E. tarda. Since this microorganism is usually isolated from aquatic environments and can cause intestinal infection, sometimes followed by bacteremia especially in immunocompromised hosts, two possible infection routes were suspected. One route was from the skin injury, leading to bacteremia. Another possible route was per oral: orally taken E. tarda invaded deeper tissues from the intestine and reach the bloodstream, leading to extraintestinal infections, although direct evidence remains elusive. Raw fish eaten 1 week prior is considered to be the most possible contaminated food. Overall mortality rate of E. tarda bacteremia is very high and the clinician should pay attention on characteristic clinical findings of E. tarda infection on cirrhotic patients.

Abstract
Little is known about iatrogenic splenic injury (SI) as an adverse event after colonoscopy. SI is sometimes fatal because of hemorrhaging. We herein report a man who developed SI after colonoscopy. He recovered conservatively. His history of left hydronephrosis and insertion with a maximally stiffened scope were suspected as possible risk factors. Endoscopists should consider the possibility of SI when they encounter patients suffering from left-sided abdominal pain after colonoscopy. Careful interview concerning the medical history and gentle maneuvering around the splenic flexure can help avoid SI.

Abstract
BACKGROUND Mild blast-induced traumatic brain injury (bTBI) induces various gut symptoms resembling human irritable bowel syndrome (IBS) as one of mental and behavioral disorders. However, the underlying mechanisms remain unclear. We investigated whether the extremely localized brain impact extracranially induced by laser-induced shock wave (LISW) evoked IBS-like phenomenon including visceral hypersensitivity and intestinal hyperpermeability in rats. METHODS The rats were subjected to LISW on the scalp to shock the entire brain. Visceral hypersensitivity was evaluated by the threshold pressure of abdominal withdrawal reflex (AWR) using a colorectal distension test. Permeability was evaluated by the concentration of penetrating FITC-dextran from intestine and the mRNA expression levels of tight junction family proteins. Involvement of corticotropin-releasing factor receptor (CRFR) 1 and 2 was examined by evaluating mRNA expression and modulating CRFR function with agonist, recombinant CRF (10 μg/kg), and antagonist, astressin (33 μg/kg). High-throughput sequencing of the gut microbiota was performed by MiSeqIII instrument and QIIME tool. KEY RESULTS The thresholds of the AWR were significantly lowered after LISW. Permeability was increased in small intestine by LISW along with decreased expression of tight junction ZO-1. LISW significantly increased CRFR1 expression and decreased CRFR2 expression. Visceral hypersensitivity was significantly aggravated by CRFR agonist and suppressed by CRFR antagonist. The α- and β-diversity of the fecal microbiota was altered after LISW. CONCLUSIONS AND INFERENCES LISW provoked visceral hypersensitivity, small intestinal hyperpermeability, altered expression of CRFRs and changes in the microbiota, suggesting that genuine bTBI caused by LISW can induce a pathophysiology comparable to that of human IBS.

Abstract
Background/Aims Recent studies indicate that probiotics, which have attracted attention as a treatment for irritable bowel syndrome, affect intestinal homeostasis. In this study, we investigated whether Zygosaccharomyces sapae (strain I-6), a probiotic yeast isolated from miso (a traditional Japanese fermented food), could improve irritable bowel syndrome symptoms. Methods Male Wistar rats were exposed to water avoidance stress (WAS). The number of defecations during WAS and the visceral hypersensitivity before and after WAS were evaluated using colorectal distension. Tight junction changes were assessed by Western blotting. Some rats were fed with strain I-6 or β-glucan from strain I-6. Changes in the intestinal microbiota were analyzed. The effect of fecal microbiota transplantation after WAS was evaluated similarly. Caco-2 cells were stimulated with interleukin-1β and tight junction changes were investigated after coculture with strain I-6. Results The increased number of stool pellets and visceral hypersensitivity induced by WAS were suppressed by administering strain I-6. The decrease in tight junction protein occludin by WAS was reversed by the administration of strain I-6. β-Glucan from strain I-6 also suppressed those changes induced by WAS. In the rat intestinal microbiota, treatment with strain I-6 altered the β-diversity and induced changes in bacterial occupancy. Upon fecal microbiota transplantation, some symptoms caused by WAS were ameliorated. Conclusions These results suggest that traditional fermented foods such as miso in Japan are valuable sources of probiotic yeast candidates, which may be useful for preventing and treating stress-induced visceral hypersensitivity.

Abstract
BACKGROUND AND AIM The study of the impact of environmental factors during pregnancy on fetal development has so far been focused primarily on those negatively affecting human health; however, little is known about the effects of probiotic treatment during pregnancy on inflammatory bowel diseases (IBD). In this study, we investigated whether oral administration of heat-killed probiotics isolated from fermented foods decreased the vulnerability of offspring to IBD. METHODS Probiotics were administered to the pregnant mice until the birth of pups, after which the parent mice were maintained with autoclaved water. Partial pups were evaluated for dextran sodium sulfate-induced colitis. The influence of CD11c+ CD103+ dendritic cells (DCs) and regulatory T cells (Tregs) in mesenteric lymph nodes of parent mice and their pups was analyzed. RESULTS Oral administration of heat-killed probiotics to pregnant dams significantly decreased inflammation induced by dextran sodium sulfate in pups. Probiotic treatment increased the number of CD103+ DCs, and the expression of β8-integrin in CD103+ DCs and Tregs in mesenteric lymph nodes, not only in dams themselves but also in their offspring. CONCLUSIONS Oral administration of probiotics during gestation induced transgenerational immunomodulatory effects on the gut-associated immune system and resilience to experimental colitis in the offspring. Our results suggest that consumption of fermented foods during pregnancy can be effective in preventing inflammatory diseases such as IBD beyond generation.

Abstract
BACKGROUND AND AIM The functions of basophils have not been elucidated until recently because of their rarity. However, with recent developments in basophil-specific antibodies and basophil-deficient animals, the roles of basophils in various diseases related to chronic inflammation have been clarified. In this study, we aimed to investigate the roles of basophils in human ulcerative colitis (UC) and oxazolone (OXA) colitis using genetically engineered Mcpt8DTR mice. METHODS Immunohistochemical staining of human colon specimens was performed to examine the involvement of basophils in the pathogenesis of UC. We examined the correlation between the number of infiltrating basophils and the UC endoscopic index of severity (UCEIS), Mayo score, and Matts score. We also examined the correlation between eosinophil count and basophil infiltration. In murine experiments, we examined whether basophil infiltration was involved in OXA-induced colitis and whether basophil depletion improved inflammation in Mcpt8DTR mice. RESULTS Colonic basophil infiltration was significantly increased in patients with UC. There were significant correlations between UCEIS, Mayo score, Matts score, and the number of infiltrating basophils. In murine OXA-induced colitis, a significant increase in basophil infiltration was observed. When basophils were depleted by diphtheria toxin in Mcpt8DTR mice, inflammation improved significantly and mRNA expression of some proinflammatory cytokines, including Tnf-α and Ifn-γ decreased significantly. CONCLUSION Basophil infiltration correlated with endoscopic, clinical, and pathological scores in human UC independently of eosinophil infiltration, and depletion of basophils ameliorated mucosal inflammation in murine OXA-induced colitis, collectively suggesting that basophils exert a proinflammatory role in chronic intestinal inflammation such as UC.

Abstract
Hepatic portal venous gas (HPVG) is considered to be a sign of poor prognosis in abdominal diseases and a potentially fatal condition. However, HPVG after colonic endoscopic submucosal dissection (ESD), is an even rarer complication that there is just one report of it at the moment. In this report, we present a case of HPVG and bacteremia that happened a day after colonic ESD in the descending colon. A 79‐year‐old female was referred to perform endoscopic treatment for a 40‐mm elevated tumor in the descending colon and surgery for clinical T1b cancer in the rectosigmoid colon. With a preoperative diagnosis of intramucosal carcinoma in adenoma, we performed ESD using carbon dioxide insufflation. The tumor was resected en bloc without any adverse events including perforation. On the following day, shivering and a fever of 38°C suddenly developed with no abdominal symptoms. Computed tomography revealed the presence of HPVG and gas in the middle colic vein without pneumoperitoneum. The patient was managed conservatively with fasting and intravenous antibiotic treatment. We confirmed the disappearance of the findings with computed tomography on the next day of the first computed tomography and with a colonoscope, we observed the base of ESD ulcer 5 days post‐ESD. HPVG might be treated conservatively, but it might cause more severe conditions such as air embolism, so this rare complication still needs to be thoroughly monitored.

Abstract
Immunoglobulin (Ig)G4‐related disease (IgG4‐RD) is a systemic condition associated with fibroinflammatory lesions and is characterized by elevated serum IgG4 levels and IgG4‐positive cell infiltration into the affected tissues. It has been reported that IgG4‐RD affects a variety of organs but uncommonly affects the gastrointestinal tract. In particular, there are few cases of lesions in the small intestine, except for sclerosing mesenteritis, which were mostly diagnosed from surgical specimens. Herein, we describe the case of a 70‐year‐old man who initially presented with abdominal pain, headache, later cognitive decline, and gait disturbance caused by IgG4‐RD. Colonoscopy revealed irregular ulcers in the terminal ileum, and computed tomography of the head showed hypertrophic pachymeningitis. Numerous IgG4‐positive cells were detected in the ileal and dural biopsies. We diagnosed the patient with IgG4‐RD and started steroid pulse therapy. After initiation of treatment, the symptoms quickly improved. The patient was discharged from the hospital after starting oral prednisolone treatment (30 mg). The dosage was gradually reduced to 10 mg. A follow‐up colonoscopy revealed scarring of the ileal ulcers. This case may provide valuable information regarding the endoscopic findings of small intestinal lesions in IgG4‐RD.

Abstract
The lymphatic vasculature returns filtered interstitial arterial fluid and tissue metabolites to the blood circulation. It also plays a major role in lipid absorption and immune cell trafficking. Lymphatic vascular defects have been revealed in inflammatory diseases, Crohn's disease, obesity, cardiovascular disease, hypertension, atherosclerosis, and Alzheimer's disease. In this review, we discuss lymphatic structure and function within the gut, such as dietary lipid absorption, the transport of antigens and immune cells to lymph nodes, peripheral tolerance, and lymphocyte migration from secondary lymphoid tissues to the lymphatics and the immune systems. We also discuss the potential roles of these lymphatics on the pathophysiology of inflammatory bowel disease and as new targets for therapeutic management.

Abstract
The lymphatic vasculature returns filtered interstitial arterial fluid and tissue metabolites to the blood circulation. It also plays a major role in lipid absorption and immune cell trafficking. Lymphatic vascular defects have been revealed in inflammatory diseases, Crohn's disease, obesity, cardiovascular disease, hypertension, atherosclerosis, and Alzheimer's disease. In this review, we discuss lymphatic structure and function within the gut, such as dietary lipid absorption, the transport of antigens and immune cells to lymph nodes, peripheral tolerance, and lymphocyte migration from secondary lymphoid tissues to the lymphatics and the immune systems. We also discuss the potential roles of these lymphatics on the pathophysiology of inflammatory bowel disease and as new targets for therapeutic management.

Abstract
A 21-year-old woman visited out hospital for lower abdominal pain and bloody diarrhoea at 19 weeks of pregnancy. Endoscopic findings revealed longitudinal ulcerations with hyperaemia and oedema in the sigmoid colon. These findings and clinical presentation confirmed the diagnosis of ischaemic colitis. Conservative treatment, including fasting and intravenous hydration, was administered, and the patient made a good recovery. After discharge, there was no recurrence during pregnancy and postpartum period. It is important to make early diagnosis and treatment, and multidisciplinary teamwork between obstetricians, gastroenterologist and endoscopist is required.

Abstract
Transmembrane location of the retinal chromophore, either native or reduced in situ to a fluorescent derivative, of the purple membrane of Halobacterium halobium was investigated with fluorescence energy transfer techniques. Single sheets of purple membrane, either native or reduced with borohydride, were adsorbed on polylysine-coated glass; the orientation, whether the exposed surfaces were cytoplasmic or extracellular, was controlled by adjusting the pH of the membrane suspension before the adsorption. On the exposed surface of the reduced membrane, a layer of cytochrome c, hemoglobin, or ferritin was deposited. The rate of excitation energy transfer from the fluorescent chromophore in the membrane to the colored protein was greater when the protein was on the cytoplasmic surface of the membrane than when it was on the extracellular surface. Analysis in which uniform distribution of the protein on the surface was assumed showed that the reduced chromophore is situated at a depth of <1.5 nm from the cytoplasmic surface. The location of the native retinal chromophore was examined by depositing a small amount of tris(2,2'-bipyridyl)ruthenium(II) complex on the native membrane adsorbed on the glass. Energy transfer from the luminescent complex to the retinal chromosphore was more efficient on the cytoplasmic surface than on the extracellular surface, suggesting that the native chromophore is also on the cytoplasmic side. From these and previous results we conclude that the chromophore, whether native or reduced, of bacteriorhodopsin is located at a depth of 1.0 +/- 0.3 nm from the cytoplasmic surface of purple membrane.

Abstract
We describe a new method for radio-frequency mandibular nerve rhizotomy under CT fluoroscopy. A patient with cancer had severe intractable and drug-resistant pain in his left mandibular region. Because he had an anatomic deformity due to cancer invasion and radiation therapy, we planned a mandibular nerve rhizotomy under CT fluoroscopic imaging. The needle was advanced to the mandibular nerve just caudal to the foramen ovale under real-time CT fluoroscopy, avoiding the cancer region. Pain scores of the patient were reduced after the nerve rhizotomy, without any complications.

Abstract
BACKGROUND Propofol is used during living-related donor liver transplantation because its metabolism is not greatly affected by liver failure. However, the pharmacokinetics of propofol during liver transplantation have not been fully defined. The purpose of this study was to evaluate the apparent systemic clearance of propofol during the dissection, anhepatic and reperfusion phases of living-related donor liver transplantation, and to estimate the role of the small intestine and lung as extrahepatic sites for propofol disposition. METHODS Ten patients scheduled for living-related donor liver transplantation were enrolled in the study. Anaesthesia was induced with vecuronium 0.1 mg kg(-1) and propofol 2 mg kg(-1), and then maintained by 60% air, 0.5-1.5% isoflurane in oxygen and a constant infusion of propofol at 2 mg kg(-1) h(-1). Apparent systemic clearance during the dissection, anhepatic and reperfusion phases was calculated from the pseudo-steady-state concentration for each phase. Disposition in the small intestine was determined by measuring arteriovenous blood concentration in 10 liver transplantation donors. Pulmonary disposition was determined by measuring the arteriovenous blood concentration in 10 recipients during the anhepatic phase. The data are expressed as mean (sd). RESULTS Apparent systemic clearances in the dissection, anhepatic and reperfusion phases were 1.89 (sd 0.48) litre min(-1), 1.08 (0.25) litre min(-1) and 1.53 (0.51) litre min(-1), respectively. The concentration of propofol in the portal vein was lower than in the radial artery. The intestinal extraction ratio calculated from the concentration in the radial artery and portal vein was 0.24 (0.12). There were no significant differences in propofol concentrations between the radial and pulmonary arteries. CONCLUSION Apparent systemic clearance was decreased by approximately 42 (10)% during the anhepatic phase compared with the dissection phase. After reperfusion, liver allografts rapidly began to metabolize propofol. The small intestine also participates in the metabolism of propofol.

Propofol (2,6-diisopropylphenol) is an intravenous anesthetic agent structurally unrelated to any other intravenous anesthetics. We examined the effect of propofol on a rat vanilloid receptor that was expressed in the human embryonic kidney (HEK) 293 cells by using calcium imaging method. Propofol caused a concentration-dependent increase in [Ca(2+)](i) in the HEK293 cells with the receptor. These responses were inhibited by removing extracellular calcium ions. The propofol-evoked increase in [Ca(2+)](i) in the HEK293 cells with the receptor was partially inhibited by capsazepine, a competitive antagonist of capsaicin. We conclude that propofol acts as an agonist for the receptor.

Abstract
We report a case of hydrothorax as a complication of laparoscopic myomectomy in an otherwise healthy woman. The most likely cause of the patient's hydrothorax was irrigation fluid moving from the peritoneal cavity into the pleural space via defects in the diaphragm. Anaesthesists and surgeons should consider hydrothorax as a potential complication in any patient undergoing laparoscopy.

Abstract
A 68-year-old female with retroperitoneal tumor extending into the inferior vena cava (IVC) developed massive pulmonary tumor embolism during removal of the tumor. Because of her unstable hemodynamics, emergency pulmonary embolectomy under cardiopulmonary bypass was performed. Successful management of her intra- and post-operative persistent right heart failure led to a satisfactory postoperative course without serious neurological complications. In peri-operative management of a patient with an extended tumor into IVC, prevention of the embolism, detection of the pulmonary embolism and treatment of intra- and post-operative right heart failure are important.

Abstract
Four ferredoxin (Fd) fractions, namely, FdA-D were purified from the green sulfur bacterium Chlorobium tepidum. Their absorption spectra are typical of 2[4Fe-4S] cluster type Fds with peaks at about 385 and 280 nm and a shoulder at about 305 nm. The A(385)/A(280) ratios of the purified Fds were 0.76-0.80. Analysis of the N-terminal amino acid sequences of these Fds (15-25 residues) revealed that those of FdA and FdB completely agree with those deduced from the genes, fdx3 and fdx2, respectively, found in this bacterium (Chung and Bryant, personal communication). The N-terminal amino acid sequences of FdC and FdD (15 residues) were identical, and agree with that deduced from the gene fdx1 (Chung and Bryant, personal communication). The A(385) values of these Fds were unchanged when they were stored for a month at -80 degrees C under aerobic conditions and decreased by 10-15% when they were stored for 6 days at 4 degrees C under aerobic conditions, indicating that they are not extremely unstable. In the presence of Fd-NADP(+) reductase from spinach, and a purified reaction center (RC) preparation from C. tepidum composed of five kinds of polypeptides, these Fds supported the photoreduction of NADP(+) at room temperature with the following K(m) and V(max) (in micromol NADP(+) micromol BChl a(-1) h(-1)): FdA, 2.0 microm and 258; FdB, 0.49 microM and 304; FdC, 1.13 microM and 226; FdD, 0.5 microM and 242; spinach Fd, 0.54 microM and 183. The V(max) value of FdB was more than twice that previously reported for purified RC preparations from green sulfur bacteria.

Abstract
We examined the effects of a general anesthetic 2, 6-diisopropylphenol (propofol) on ATP- and alpha,beta-methylene ATP (alphabetameATP)-activated currents in the human embryonic kidney 293 (HEK 293) cells expressing recombinant P2X receptor channels, using the whole-cell patch-clamp method. Propofol at clinical relevant concentrations ( approximately 56 microM) potentiated the current responses through the P2X(4) receptor in a dose-dependent manner, whereas propofol did not affect the responses through the P2X(2) receptor or through the heterologous complex of the P2X(2) and P2X(3) (P2X(2+3)) receptor. These results suggest that activation of P2X(4) subtype in the brain and the motor neurons of the spinal anterior horn might be involved in the excitatory effect by propofol such as convulsion and unexpected movements.

Abstract
L-Sorbose, an excellent cellulase and xylanase inducer from Trichoderma reesei PC-3-7, also induced alpha-L-arabinofuranosidase (alpha-AF) activity. An alpha-AF induced by L-sorbose was purified to homogeneity, and its molecular mass was revealed to be 35 kDa (AF35), which was not consistent with that of the previously reported alpha-AF. Another species, with a molecular mass of 53 kDa (AF53), which is identical to that of the reported alpha-AF, was obtained by a different purification procedure. Acid treatment of the ammonium sulfate-precipitated fraction at pH 3.0 in the purification steps or pepsin treatment of the purified AF53 reduced the molecular mass to 35 kDa. Both purified enzymes have the same enzymological properties, such as pH and temperature effects on activity and kinetic parameters for p-nitrophenyl-alpha-L-arabinofuranoside (pNPA). Moreover, the N-terminal amino acid sequences of these enzymes were identical with that of the reported alpha-AF. Therefore, it is obvious that AF35 results from the proteolytic cleavage of the C-terminal region of AF53. Although AF35 and AF53 showed the same catalytic constant with pNPA, the former showed drastically reduced specific activity against oat spelt xylan compared to the latter. Furthermore, AF53 was bound to xylan rather than to crystalline cellulose (Avicel), but AF35 could not be bound to any of the glycans. These results suggest that AF53 is a modular glycanase, which consists of an N-terminal catalytic domain and a C-terminal noncatalytic xylan-binding domain.

Abstract
Thin sheets of Ac-Tm-Tn paracrystals were prepared in the presence of high concentration of Ca2+ ion and three-dimensional image analysis was performed. The optical diffraction pattern of an electron micrograph showed spots up to 1/1.6 nm-1 in the radial direction and up to 1/2.5 nm-1 in the axial direction, the best resolution ever obtained so far. The translationally filtered image showed clear polarity of filament which looked like a "spearhead" per each crossover repeat of actin helix. The three-dimensionally reconstructed model looked very similar to the inner regions (A+B domains) of the Ac-Tm-S1 complex obtained by Toyoshima and Wakabayashi (14, 15) when they were placed so that the "spearhead" pattern of the Tc-Tm-Tn complex and the "arrowhead" pattern of the Ac-Tm-S1 complex pointed in the same direction. The myosin-binding site of actin was identified by comparison of the two structures. The model of actin molecule cut out from the thin filament model had a low density region within itself, which was located about 2.5 nm from the helix axis. That low density region divided actin molecule into two domains, a large and a small domain. A dense "pillar" was detected which connected two neighboring actin molecules along a left-handed generic helix 1 nm from the helix axis. Two actin-actin binding sites which were responsible for the connection through the "pillar" were located on the inner surface of actin molecule. To obtain better crystalline arrays of actin, we tried a method utilizing adsorption to lipid. A positively-charged monolayer of lipids was formed on the surface of a small volume of buffer solution which was put in a microwell. Solution of negatively-charged F-actin was then injected into the buffer solution and was allowed to be joined to the lipid monolayer by electrostatic attraction. Fluidity of the lipid monolayer enabled the two-dimensional crystallization of actin. Electron microscopy revealed that larger paracrystalline arrays were formed more rapidly (less than 1 hr) than those formed within solution, which demonstrated the advantage of this adsorption method.
