Belladonna has a triple action on the intestines:? (1) It opens the gates, i.e., relaxes the sphincters; (2) it diminishes the spasmodic narrowingof the large intestines; and (3) it antagonises the vaso-constrictor action of the intestinal bacteria] toxins and thus acts as a physiological antidote to them. The drug should be pushed to its full physiological effects, the result being most satisf...

Studies have been made of the digestion of nitrogen (N) and of organic matter (OM) in sheep offered thirteen gramineous roughages of widely differing nutritive value. It was concluded that the true digestibility of crude protein in the intestines ranged from 74 to 82% (mean 78%). These estimates were based on observations that, while metabolic faecal N (MFN) was equal to 0.4 g/100 g OM intake, ...

Inducible nitric oxide synthase (iNOS) was shown to be expressed in normal mucosa and adenoma of small and large intestines of Apc mice by reverse transcription-PCR and immunohistochemistry. Administration of the iNOS inhibitor aminoguanidine (1.5 g/liter) in drinking water or an L-arginine-deficient diet to Apc mice resulted in a significant decrease in adenoma development in the small but not...

Methods An isolated model of the rat small bowel (1) was used. Intestines were stimulated with a 0.5 nmol PAF bolus via the mesenteric artery alone (PAF, n=5) or after pretreatment with IBMX (100μM) and forskolin (0.5μM) for 20 min (PAF+PDE/AC, n=4) to increase intracellular cAMP by inhibition of phosphodiesterase (PDE) and stimulation of adenylate cyclase (AC). The pressure responses, the vasc...

To ingest milk the lactose is hydrolyzed (processed) in the small intestines, for this to happen the small intestines secretes the enzyme called lactase which splits the lactose molecule in two producing sugar glucose and galactose; this is then absorbed into the bloodstream. If the lactose remains unhydrolyzed i.e not processed it can lead to intestinal symptoms including stomach gas, distensi...

Aims: This study was carried out to investigate the carcass characteristics of male and female rabbits raised in semi-arid condition.Methods Results: Twenty-four (24) rabbits, comprising 12 bucks does, were used for this study. At weeks age, weighed slaughtered. Parameters measured include; pre-slaughter weight (kg), hot (g), four primal cut weights (shoulder, ribs, loin rump), internal organs ...

Fluorescent oligonucleotide probes targeting rRNA were used to develop an in situ hybridization technique by which the spatial distribution of Escherichia coli in the large intestines of streptomycin-treated mice was determined. Single E. coli cells were identified in thin frozen sections from the large intestines by the use of a probe specific for E. coli 23S rRNA. Furthermore, the total bacte...

The traditional understanding is that an entirely new complement of digestive enzymes is secreted by the pancreas into the small intestines with each meal. This is thought to be necessary because, like food itself, these enzymes are degraded during digestion. In this review we discuss experiments that bring this point of view into question. They suggest that digestive enzymes can be absorbed in...

Abundance of ingested debris by seals has been mentioned as a potential indicator of marine litter in the European Marine Strategy Framework Directive (MSFD). A sample of 107 stomachs, 100 intestines and 125 scats of harbour seals from the Netherlands was analysed for the presence of plastics. Incidence of plastic was 11% for stomachs, 1% for intestines, and 0% for scats. Younger animals, up to...
