To study the effects of dietary fat on jejunal water and ion absorption and on cholera toxininduced secretion, 3 week old Sprague Dawley rats were fed isocaloric diets. Forty per cent of the total calories were given as fat, as butter (high saturated fat), olive oil (high monounsaturated fat), or corn oil (high polyunsaturated fat), with one group on low fat (10% of calories) standard laborator...

The presence of steatorrhoea in pancreatic fibrosis was formerly the cause of its confusion with coeliac disease. This confusion was dispelled by the studies of Blackfan and Wolbach (1933) and of Andersen (1938) who clearly separated pancreatic fibrosis as a separate entity by showing that in this disease there was atrophy of the secretory tissue of the pancreas and that the steatorrhoea result...

Interference with fat hydrolysis results in the reduced use of ingested lipids. Inhibition of pancreatic lipase reduces the efficiency of fat absorption in the small intestine and thereby initiates modest long-term reduction in body weight. In an attempt to select peptides with affinity for the surface of pancreatic lipase and potential inhibitory activity, a random, cyclic heptapeptide phage-d...

INTRODUCTION Malabsorption, which is frequently underdiagnosed in critically ill patients, is clinically relevant with regard to nutritional balance and nutritional management. We aimed to validate the diagnostic accuracy of fecal weight as a biomarker for fecal loss and additionally to assess fecal macronutrient contents and intestinal absorption capacity in ICU patients. METHODS This was an...

Duck meat sausages were prepared using 10% beef fat (FDS) and 10% hydrated cereal flours including rice (RDS), wheat, corn, millet, and barley to replace fat. Control duck sausages (DS) were also prepared only with duck meat and duck meat plus 10% beef fat. Results showed that protein and fat contents significantly decreased and total expressible fluid reduced with the addition of cereal flours...

Context Vitamin D is frequently prescribed as a supplement, yet its absorption remains poorly understood. Objective This systematic review was performed to evaluate data on mechanisms involved in the intestinal absorption of vitamin D. Data Sources PubMed, Embase, and Cochrane Library databases were searched. Study Selection The following studies were included: experimental laboratory stu...

It was found that dogs with a subcutaneous transplant secreting and discharging pancreatic juice externally absorbed no more fat than dogs in which the pancreatic remnant was undergoing rapid atrophy and sclerosis. Hence, the condition of the pancreatic tissue remaining in the body does not influence the amount of fat absorbed by the intestine. The absorption of fat by the intestinal mucous mem...

The nutritional factors which affect lead absorption have been studied. Synthetic diets of known composition were compounded to contain 0-075% Pb as PbCl2 labelled with 203Pb. Rats were exposed to lead for periods of 48 hr. The dietary intake was then measured and the absorption of lead determined by means of a whole-body counter. Lead absorption was increased by high fat, low mineral, low prot...
