BACKGROUND Treatment of acromegaly with octreotide increases the proportion of deoxycholic acid in, and the cholesterol saturation of, bile and induces the formation of gallstones. Prolongation of intestinal transit has been proposed as the mechanism for the increase in the proportion of deoxycholic acid in bile. AIMS To study the effects of octreotide on intestinal transit in acromegalic pat...

objectives: mentha longifolia l. (lamiaceae) is an annual herb that is used in the iranian traditional medicine for treating stomach and intestinal disorders. the purpose of this study was to determine the protective effect of m. longifolia on experimental diarrhea in a rat model. materials and methods: the antidiarrheal activity of essential oil of m. longifolia (20-80 mg/kg) was investigated ...

BACKGROUND Acyl ghrelin-induced intake depends on hypothalamic neuropeptide Y and agouti-related protein (AgRP) neurotransmitters. Intracerebroventricular (ICV) injection of AgRP increases feeding through competitive antagonism at melanocortin receptors. ICV administration of α-melanocyte stimulating hormone (α-MSH), a natural antagonist of AgRP, may modulate the acyl ghrelin-induced orexigenic...

The small intestine represents the region where the majority of drug and nutrient absorption transpires. Among adults, small intestinal transit kinetics is well delineated; however, the applicability of these values toward children remains unclear. This article serves to examine the relationship between age and mean small intestinal transit time (SITT) based on the available literature. In addi...

Objective(s) This study was aimed to assess the possible laxative and prokinetic effects of the boiled extract of Rosa damascena. Materials and Methods Rats in two groups (n= 7) of test and control were gavaged either with the extract or placebo, respectively. The number, weight and water percentage of feces were studied up to 24 hr. In order to assess the possible osmotic laxative effects of t...

The aim of this study was to investigate effects of synchronized intestinal electrical stimulation (SIES) on small intestinal motility in dogs. Seventeen dogs were equipped with a duodenal cannula for the measurement of small bowel motility using manometry; an additional cannula was equipped in six of the dogs with 1.5 m distal to the first one for the measurement of small intestinal transit. T...

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...

Introduction: Artemisia dracunculus L. belongs to Asteraceae family, and is a medicinal plant widely used in traditional medicine as a remedy for gastrointestinal disturbances. This study was undertaken to evaluate the effects of essential oil of A. dracunculus (EOAD) on the rat alimentary tract. Methods: The EOAD was extracted by Clevenger apparatus using hydrodistillation. LD50 was calcula...

BACKGROUND AND AIMS Several conditions that delay gastrointestinal transit are associated with unconjugated hyperbilirubinaemia. We hypothesised that the gastrointestinal transit time is directly related to plasma unconjugated bilirubin (UCB) concentrations, and that this relationship can be used to develop a new therapeutic strategy for severe unconjugated hyperbilirubinaemia in the Gunn rat m...
