The effects of a fraction (T1) of Tityus serrulatus scorpion venom prepared by gel filtration on gastric emptying and small intestinal transit were investigated in male Wistar rats. Fasted animals were anesthetized with urethane, submitted to tracheal intubation and right jugular vein cannulation. Scorpion toxin (250 microg/kg) or saline was injected iv and 1 h later a bolus of saline (1.0 ml/1...

[Purpose] This study aimed to examine the effects of interventions on constipation and to provide basic data for physical therapy in internal medicine. [Subjects and Methods] The colon transit times of 30 subjects were measured and after the interventions. Fifteen subjects were assigned to a Maitland orthopedic manual therapy group, and 15 subjects were assigned to a dietary fiber group. [Resul...

Chronic Constipation is a debilitating condition that is often associated with different abdominal problem. It can cause distress for the child and family and can result in emotional disturbance and family problem. Based on the current algorhytm, the treatment of chronic constipation consists of 4 important phases, 1: education, 2: disimpaction, 3: prevention of re-accumulation of feces and 4: ...

Free fatty acid receptor 2 (FFA2) is expressed on enteroendocrine L cells that release glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) when activated by short-chain fatty acids (SCFAs). Functionally GLP-1 and PYY inhibit gut transit, increase glucose tolerance, and suppress appetite; thus, FFA2 has therapeutic potential for type 2 diabetes and obesity. However, FFA2-selective agonists have...

Studies were performed on 20 male adult rats to investigate the effects of chronic intermittent infusion of lipid and physiological emulsifier into the distal small intestine on stomach to caecum transit time (SCTT) of the head of a test meal. SCTT was measured using environmental hydrogen analysis. Ileal lipid infusion normally delays gastric emptying and small intestinal transit (p < 0.001), ...

OBJECTIVE To measure the thickness of the crypts and quantify the number of goblet cells of the colonic mucosa with and without intestinal transit, relating them to exclusion time. METHODS Sixty Wistar rats were divided into three groups of 20 animals each according to the time of the final operation for the removal of the colon, in six, 12 or 18 weeks. In each group 15 animals underwent colo...

The actions of nutrients on gut transit of liquids and solids have been extensively studied, but the effects of meal ingestion on intestinal gas flow are unexplored. We hypothesized that meals of varying caloric content and consistency modulate gas transit to different degrees. Nine healthy volunteers underwent jejunal perfusion of physiological gas mixtures at 12 ml.min(-1).3 h, with ingestion...
