Mechanisms of Intragastric pH Sensing
Luminal amino acids and lack of luminal acidity as a result of acid neutralization by intragastric foodstuffs are powerful signals for acid secretion. Although the hormonal and neural pathways underlying this regulatory mechanism are well understood, the nature of the gastric luminal pH sensor has been enigmatic. In clinical studies, high pH, tryptic peptides, and luminal divalent metals (Ca(2+...
متن کاملIntravenous omeprazole rapidly raises intragastric pH.
Twenty four hour intragastric acidity was measured in five duodenal ulcer patients studied at least three times. The effects of different dosage regimens of intravenous omeprazole was compared with placebo. Mean intragastric acidity from 1000 to 0800 was 34.3 +/- 4.3 mmol/l on placebo. After omeprazole 80 mg at 0900 and 40 mg at 1700 mean acidity was 2.1 +/- 0.9 mmol/l and after omeprazole 80 m...

15 صفحه اولEffect of intragastric pH on mucosal protective action of sucralfate.
Acid intragastric pH is believed to be mandatory for mucosal protective action of sucralfate, but evidence for its efficacy at neutral pH is lacking. The effect of sucralfate on gastric mucosal erosions induced by oral administration of aspirin and bile acids at acidic pH of 1.5 and 3.9, and near neutral pH of 6.5 was investigated in 320 rats. The effect of sucralfate on the intragastric pH fou...
متن کاملUse of automatic computerised pump to maintain constant intragastric pH.
We used continuous variable rate infusions of famotidine in eight normal volunteers under fasting conditions to raise intragastric pH to 5.0. An intragastric glass electrode continuously monitored acidity and this information was automatically computed to regulate an intravenous infusion system (GastroJet). The computer was programmed to aim for pH 6.0, increasing and lowering infusion rates ac...
