Four Texel wethers (60 to 64 kg) fitted with rumen and duodenal cannulae were used to compare methods for estimating mean retention times (MRT) of digesta markers. They were fed, in eight equal meals, 1,200 g of a mixture of a chopped and ground (8-mm screen) and pelleted orchardgrass hay in the ratios 90/10, 50/50, 30/70, or 10/90 according to a 4 x 4 Latin square design. Mean retention time i...
BACKGROUND Patients with celiac disease who present with symptoms of gastrointestinal hypomotility have abnormal antroduodenal manometry. There are no data on antroduodenal manometry in malabsorption syndrome (MAS) due to causes other than celiac disease. METHODS Fasting, post-prandial and post-octreotide antroduodenal motility parameters were compared in 18 untreated patients with MAS presen...
The effect of various drugs on the extracellular concentration of dopamine in two terminal dopaminergic areas, the nucleus accumbens septi (a limbic area) and the dorsal caudate nucleus (a subcortical motor area), was studied in freely moving rats by using brain dialysis. Drugs abused by humans (e.g., opiates, ethanol, nicotine, amphetamine, and cocaine) increased extracellular dopamine concent...
Cholesterol gallstones are associated with slow intestinal transit in humans as well as in animal models, but the molecular mechanism is unknown. We investigated in C57L/J mice whether the components of a lithogenic diet (LD; 1.0% cholesterol, 0.5% cholic acid and 17% triglycerides), as well as distal intestinal infection with Helicobacter hepaticus, influence small intestinal transit time. By ...
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...
MK-801 induces psychotomimetic behavioural changes in animals. ERKs play an important role in the pathogenesis of schizophrenia and in the action of antipsychotics and psychotomimetics. We observed phosphorylation of ERK-signalling-pathway-associated molecules in the rat frontal cortex and their association with rat behaviour after MK-801 administration. After injecting 0.25-1 mg/kg MK-801, ERK...
