Abstract
Background and Aim The prevalence of ulcerative colitis has increased in Asian populations in recent years. This Japanese internet survey investigated the symptoms, impact, and treatment of ulcerative colitis, and communication between patients and medical professionals. Methods This was a non-interventional analysis of responses from participants with ulcerative colitis who had regularly visited medical providers for their disease in the past year. Results In 501 evaluable participants, the mean age was 39.8 years and mean disease duration was 7.6 years. Ulcerative colitis had a "significant impact" on daily life in 43.5% of participants who experienced bowel urgency and 48.6% who experienced bowel incontinence. Although the prevalence of bowel urgency and bowel incontinence was associated with higher stool frequency and rectal bleeding scores (p value for trend <0.0001), they still existed even in patients without frequent stools or rectal bleeding. Around 30% of participants hesitated to discuss symptoms such as bowel incontinence with a medical professional. Approximately three-quarters preferred to use websites for medical information. Most participants (78.0%) had used topical treatments. However, 25.7% were hesitant to use such treatments due to concerns about discomfort (48.1%) and administration difficulty (47.3%). Conclusions Ulcerative colitis significantly affects daily life, largely due to symptoms such as bowel urgency and bowel incontinence. Despite desiring to improve bowel incontinence, patients are embarrassed to consult physicians or nurses. Therefore, medical professionals should make an active effort to draw out patients' individual concerns, including symptoms that patients may not initially feel able to talk about openly.

Abstract
BACKGROUND In Crohn's disease (CD), the involvement of food antigens in immune responses remains unclear. The objective of this study was to detect immune responses against food antigens in CD patients and examine the mechanism in a mouse model of colitis. METHODS We enrolled 98 CD patients, 50 ulcerative colitis patients, and 52 healthy controls (HCs) to compare the levels of serum immunoglobulin (Ig)Gs against 88 foods. The presence of serum IgGs against foods was also examined in interleukin (IL)-10 knockout (KO) mice in which CD4(+) T cell activation by antigenic food protein was assessed. Mice transferred with IL-10 KO cells received diets with or without food antigens, and the development of colitis was evaluated. RESULTS The prevalence of IgGs against various foods, especially vegetables, grains, and nuts, was significantly higher in CD patients than in HCs. Similarly, the prevalence of IgGs against food proteins was higher in IL-10 KO mice than in BALB/c mice. Beta-conglycinin, identified as an antigenic food proteins in IL-10 KO mice, induced CD4(+) T cell production of interferon-γ and IL-17 through dendritic cell antigen presentation. Elimination of the food antigens ameliorated the development of colitis in mice without altering the composition of their intestinal microbiota. CONCLUSIONS In CD colitis mice, intestinal inflammation via CD4(+) T cell hyperactivation was induced by food antigens associated with high serum IgG levels and was ameliorated by the elimination of food antigens. This disrupted immunological tolerance to food antigen, which might act as an exacerbating factor, remains to be elucidated in CD patients.

Abstract
BACKGROUND Chronic intestinal inflammation is frequently accompanied by motility disorders. We previously reported that proinflammatory cytokines, such as tumor necrosis factor alpha and interleukin (IL)-1beta downregulate CPI-17, an endogenous inhibitor of serine/threonine protein phosphatase in smooth-muscle cells, which results in the inhibition of myosin light chain phosphorylation and contractility. However, its clinical relevance has not been clarified. METHODS The present study examined the changes in CPI-17 expression in chronic intestinal inflammation using smooth-muscle tissues from IL-10 knockout mice and from patients with ulcerative colitis (UC). RESULTS The IL-10 knockout mice developed spontaneous and chronic colitis accompanied by immune cell infiltration, submucosal fibrosis, and thickening of the muscularis externa. The expression of alpha-smooth muscle actin protein in the smooth-muscle layer did not change, whereas that of CPI-17 protein was decreased by about 40% compared with healthy wild-type controls. Consistent with this observation, smooth-muscle contractile force and myosin light chain phosphorylation induced by a muscarinic agonist were reduced in the knockout mice. Moreover, we observed that CPI-17 protein expression was decreased in smooth-muscle tissues from patients with UC compared with controls. CONCLUSIONS CPI-17 downregulation might contribute to the decreased motor function in chronic inflammatory bowel diseases.

Abstract
A number of rodent models for inflammatory bowel disease (IBD) have been developed, but most cannot be used to develop and validate new therapies for IBD. From the models developed, the IL-10 deficient mouse model is the one that results in a disease similar to human IBD; however, in this model, colitis occurs with variable incidence taking 3-4 months to develop. These are serious problems with the model when evaluating a new therapy because of the large-scale experiments required and the difficulty in performing an accurate pharmacological analysis. In this study, the IL-10 deficient mouse model was modified by transferring whole spleen and mesenteric lymph node cells from IL-10 deficient mice to CB-17 SCID mice. In this IL-10 deficient cell transfer model, chronic intestinal inflammation developed in all recipients within 2-3 weeks, which was far earlier than in donor IL-10 deficient mice. The pathological phenotypes were similar to those of IL-10 deficient mice and CD45RBhi T cell-transfer models. In addition, we assessed several agents for inflammatory bowel disease to validate the general utility of this cell transfer model. It is worth noting that TNFR-Ig or prednisolone, which is effective for treatment of patients with severe-fulminant Crohn's disease, markedly attenuated pathological clinical indices in this colitis model, whereas the immunosuppressive agents, azathioprine, tacrolimus, and cyclosporine A produced no significant effect. These results suggest that the IL-10 deficient cell transfer model is a good experimental model to use for developing new and effective therapies for active IBD.

Abstract
1. In the rabbit isolated aorta and trigone of the bladder, noradrenaline, phenylephrine and clonidine elicited concentration-dependent contractions, which may be caused through activation of postsynaptic alpha 1-adrenoceptors. 2. SHI437, IK29, prazosin and yohimbine competitively antagonized the contractile responses induced by noradrenaline in the aorta and trigone. The pA2 values of SHI437, IK29, prazosin and yohimbine were 7.35 +/- 0.09, 7.47 +/- 0.10, 8.55 +/- 0.02 and 6.28 +/- 0.05 in the aorta, and 8.07 +/- 0.04, 8.30 +/- 0.03, 8.22 +/- 0.04 and 6.46 +/- 0.04 in the trigone, respectively. 3. SHI437, IK29, prazosin and yohimbine also possessed competitive alpha 2-adrenoceptor blocking properties, judging from their antagonism of the clonidine-induced inhibitory effect on the twitch responses in the electrically stimulated vas deferens of the rat. The pA2 values of SHI437, IK29, prazosin and yohimbine were determined to be 4.76 +/- 0.02, 4.74 +/- 0.02, 5.06 +/- 0.03 and 7.86 +/- 0.04, respectively. 4. SHI437, IK29 and prazosin inhibited the contractile responses elicited by transmural electrical stimulation without affecting the evoked 3H-overflow from the [3H]-noradrenaline-preloaded rabbit aorta. Yohimbine augmented the contractile responses and 3H-overflow. 5. SHI437 and IK29 at a concentration sufficient to inhibit noradrenaline-induced contraction failed to attenuate the contractile responses of aorta to KCl, 5-hydroxytryptamine and prostaglandin F2 alpha, and of the trigone to acetylcholine and histamine. 6. The present results suggest that SHI437 and IK29 are highly selective alpha 1-adrenoceptor antagonists, especially in the trigone of the bladder.
