Despite the current increase in interest in the role of the microbiota in health and disease and the recognition, for over 50 years, that an excess of colonic-type flora in the small intestine could lead to a malabsorption syndrome, small intestinal overgrowth remains poorly defined. This lack of clarity owes much to the difficulties that arise in attempting to arrive at consensus with regard t...

The effect of 5-hydroxytryptamine (5-HT) on the crypt cell production rate in normal human duodenal mucosa cultured in vitro was studied using a stathmokinetic technique with crypt microdissection. The addition of 5-HT (2 mg/ml) to the culture medium significantly increased the crypt cell production rate (p < 000 1), suggesting that this amine may have a trophic effect on crypt cells in vitro. ...

Proximal and distal small intestinal segments of the rat were perfused in situ at two different rates with isotonic solutions containing glucose in concentrations ranging from 25 to 600 mg/100 ml. Absorption was measured as glucose disappearance rate from the lumen. Glucose absorption had not previously been studied at intraluminal concentrations above and below blood glucose. Absorption was mo...

The importance of friendly bacteria in the large intestine is becoming clearer. In fact, the recent focus of research on the beneficial bacteria in the large intestine and their relationship with health outcomes has been hard to ignore. Study after study indicates that the gut microbiome is intricately related to our health and well-being. However, the extent of the benefits of the gut bacteria...

Crocin is a plant-derived carotenoid and bears potent antioxidant property. Ranitidine (a histamine H2 receptor blocker) is used for peptic ulcer treatment. The present study was planned to investigate the effects of crocin and ranitidine on indomethacin-induced ulcer in small intestine of rats. Animals were randomized into two major groups including indo-methacin (10.00 mg kg-1...

Objective. Balloon enteroscopy (BE) and capsule enteroscopy (CE) are enteroscopy methods that allow examination and treatment of the small bowel. Before the CE and BE era, the small intestine was difficult to access for investigation. Small intestinal tumours are infrequent conditions, but about half of them are malignant. Materials and Methods. A total of 303 BEs were performed in 179 patients...

Gastrointestinal motility is an integrated process including myoelectrical and contractile activity, tone, compliance and transit. The techniques for the assessment of gastrointestinal motility are multiple and all have their advantages and disadvantages. In the case of suspected abnormal upper gut transit, gastric and small bowel transit scintigraphy followed by small intestinal (antroduodenoj...

Pycnocycla spinosa Decne. ex Boiss. var. spinosa (Fam. Umbelliferae) is an essential oil-containing wild plant growing in central part of Iran. Hydroalcoholic extract of Pycnocycla spinosa has antispasmodic and antidiarrheal activity. The aim of this study was to further investigate antidiarrheal and small intestinal transit effect of P. spinosa extract for a comparison with loperamide and dicy...
