...- and seawater-acclimated killifish. In intact animals, there was no change in acid or base flux to the external water after the meal, in accord with the absence of any post-prandial alkaline tide in the blood. Indeed, freshwater animals exhibited a post-prandial metabolic acidosis (‘acidic tide’), whereas...

... balance regulation appears negligible in studies of unfed fish, but evidence of high intestinal fluid [HCO 3 − ] in fed marine teleosts led us to investigate the source of this HCO 3 − and its potential role in offsetting the postprandial ‘alkaline tide’ commonly associated with digestion. Specifically...

.... An alkaline tide in the blood also occurred at 6 h. In the face of large changing masses of highly acidic chyme in the stomachs, the pH (6.50±0.10), ionic composition and volume of chyme in the intestine (spiral valve) were precisely regulated from 6 to 60 h post-feeding at very different values from those...

... for an especially pronounced alkaline tide response in these animals (for a review, see Wang et al.,2001 ). Intestinal HCO - 3 secretion may also act in part to regulate acute dietary Ca 2+ influx. In addition to a larger influx of HCl to the intestine of toadfish fed sardines, maximal Ca 2+ concentrations...

...L. K. Hartzler; S. L. Munns; A. F. Bennett; J. W. Hicks SUMMARY A large alkaline tide (up to 20 mmol l –1 increase in bicarbonate concentration [HCO 3 – ] with an accompanied increase in blood pH) has previously been reported for some carnivorous reptiles within 24 h after ingesting a large meal...

...Denis V. Andrade; Luis Felipe De Toledo; Augusto S. Abe; Tobias Wang SUMMARY The increased metabolic rate during digestion is associated with changes in arterial acid–base parameters that are caused by gastric acid secretion(the `alkaline tide'). Net transfer of HCl to the stomach lumen causes...
