In human, digestive disorders are often associated with visceral pain. In these pathologies, visceral pain threshold is decreased indicating a visceral hypersensitivity. Pregabalin [CI-1008; S-(+)-3-isobutylgaba] presents antihyperalgesic actions in inflammatory somatic pain models. This study was designed to evaluate 1) the effect of injection of TNBS into the colon on visceral pain threshold,...
Animal studies demonstrate that nizatidine, an H2-receptor inhibitor, may enhance colonic activity independent of its effect on acid secretion. The effect of nizatidine on human colonic motility is unknown. We evaluated the potential prokinetic property of nizatidine in 12 healthy subjects (10 men and 2 women, age 21-46 years). Each subject received either nizatidine (600 mg), famotidine (80 mg...
introduction: ulcerative colitis (uc) is a chronic colonic mucosal disease with unknown etiology. its frequency is rising in our country in recent years. with application of newer topical preparation in treatment of uc a true recognition of its colonic extension pattern is needed. reports from iran are scarce. reports from the world are contradictory. this study, therefore, was done to determi...
background: routine screening colonoscopy is on the rise and pathologists have to deal with the ever larger numbers of excised colonic polyps. it is very important to optimize the patients’ individual treatment and further surveillance. pathologists play a critical role in management, as most of the clinical decisions concerning colonic polyp management are based on pathologic findings. one of ...
Recently, we reported that nicotine in vitro at a low 1-μM concentration suppresses hyperexcitability of colonic dorsal root ganglia (DRG; L(1)-L(2)) neurons in the dextran sodium sulfate (DSS)-induced mouse model of acute colonic inflammation (1). Here we show that multiple action potential firing in colonic DRG neurons persisted at least for 3 wk post-DSS administration while the inflammatory...
BACKGROUND Colonic involvement in amebic liver abscess (ALA) occurs in more than half of the patients. However no studies have found any association between the site of the colonic lesions and location of abscesses in the liver. Thus, the present study was designed to find the correlation between colonic involvement in solitary and multiple ALAs. METHODS This is a case control study of 80 pat...
objective: the objective of this study is to develop and assess targeted pamam-peg nanocarrier with anti-tag72 nanobody for t-bid gene coding construct delivery into the human colonic adenocarcinoma cells. materials and methods: nanobody (nb) coding sequence was subcloned into psj expression vector for large-scale production and then nb was purified by ni++ affinity chromatography. sds-page an...
Overexpression of human progastrin increases colonic mucosal proliferation and colorectal cancer progression in mice. The G-protein coupled receptor 56 (GPR56) is known to regulate cell adhesion, migration, proliferation and stem cell biology, but its expression in the gut has not been studied. We hypothesized that the promotion of colorectal cancer by progastrin may be mediated in part through...
The increase in incidence of colonic diverticular bleeding is relative to an age-related rise in the incidence of colonic diverticulosis and use of antithrombotic medication. However, risk factors related to the onset, recurrence, and prophylaxis have not been established. Therefore, we aimed to determine risk factors for the onset and recurrence of colonic diverticular bleeding.An age- and sex...
Unitary discharges were recorded from the inferior mesenteric ganglion of decerebrate dogs. Eighty-one units were identified as sympathetic postganglionic neurons innervating the colon and rectum by collision test performed by stimulation of the lumbar colonic nerve. Discharges of four units were enhanced simultaneously with an increased outflow of the renal nerve by pinching a toe. Thus, those...
