To determine the stomach bioreactor capability for food oxidation or antioxidation, rats were fed red turkey meat cutlets (meal A) or red turkey meat cutlets and red wine concentrate (meal B). The hydroperoxides (LOOH) and malondialdehyde (MDA) levels of the stomach contents were evaluated during and after digestion; the postprandial plasma MDA level was also evaluated. In independently fed rat...

partaken of a quantity of datura leaves, prepared in the form of curry, with rice, which he afterwards acknowledged to have voluntarily taken. On admission, he lay perfectly unconscious, with severe spasmodic muscular twitchings and stertorous breathing. Skin cool; pulse about 108?, feeble. Pupils dilated and insensible to the effects of light. The stomach pump was immediately introduced, but d...

Gastric digestion of protein is dependent on the hydrogen ion concentration of the stomach contents. Human gastric juice will digest casein optimally in the pH ranges 1 * 8 to 2 2 and 3 * 5 to 3 * 6. Between and above these ranges hydrolytic activity rapidly declines and is minimal between pH 2-5 and 3*2 (Taylor, 1959). Pepsin is the main enzyme concerned, but others, i.e. parapepsins, have bee...

The effects of duodenal reflux on gastric secretion have been examined in dogs. Acid secretion during pentagastrin stimulation increased by 68% in animals with chronic diversion of duodenal contents into the stomach. This increased acid secretion did not occur when bile alone was diverted into the stomach and could be abolished by vagotomy. The hypersecretion observed with pentagastrin did not ...

Horses are exquisitely sensitive to non-specific gastrointestinal disturbances as well as systemic and extraintestinal conditions related to gut health, yet minimal data are available regarding the composition of the microbiota present in the equine stomach, small intestine, and cecum and their relation to fecal microbiota. Moreover, there is minimal information regarding the concordance of the...

Potamotrygonid stingrays are restricted to Neotropical rivers and information on their diet remains scarce. Thus, the prey composition of four freshwater stingray species from the middle Negro River was studied using stomach contents analysis: Potamotrygon motoro (n=40), Potamotrygon orbignyi (n=27), Potamotrygon sp. “cururu” (n=26), and Paratrygon aiereba (n=34). Prey items were identified up ...
