the effectiveness of an enzymatic cocktail, collagenase and trypsin, on the absorptive function of ilealsegment was studied to evaluate the changes within groups after performing ileocystoplasty in an animalmodel. twenty-one female mixed-bred persian dogs were randomized into 7 groups. the groups included: 1) negative control group (ncg) in which no ileocystoplasty was performed (n = 3); 2) pos...

The normal gut is adapted to intermittent feeding with complex macromolecular substrates of low sodium content. The high permeability of the upper small intestine to sodium, together with sodium rich saliva and pancreaticobiliary secretions results in large sodium fluxes into the lumen. These substantial sodium influxes are matched by equally large effluxes from the ileum and proximal colon, wh...

To define the iron absorptive phase across the intestinal mucosa of neonatal pigs, the final SgFe concentration ratio of serosal to mucosal medium of everted gut sac at 1 hr incubation was measured. With .2 btg carrier iron (ferric citrate with molecular weight of 1,500) per milliliter of both the serosal and mucosal medium, the duodenum transported the iron against the concentration gradient f...

BACKGROUND A common characteristic of Trichuris spp. infections in humans and animals is the variable but low efficacy of single-dose benzimidazoles currently used in mass drug administration programmes against human trichuriasis. The bacillary band, a specialised morphological structure of Trichuris spp., as well as the unique partly intracellular habitat of adult Trichuris spp. may affect dru...
