... incorporation and the subsequent synthesis of nitrogenous compounds (urea, glutamine, bulk amino acids, protein) in the intestinal spiral valve, plasma, liver and muscle. Within 20 h post-feeding, we found labelled nitrogen was incorporated into all tissues examined. The highest δ 15 N values were seen...

...Yoshio Takei; Marty K. S. Wong; Masaaki Ando ABSTRACT The intestine of marine teleosts secretes HCO 3 − into the lumen and precipitates Ca 2+ and Mg 2+ in the imbibed seawater as carbonates to decrease luminal fluid osmolality and facilitate water absorption. However, the hormonal regulation of HCO...

... nitrogen in the gills, kidney, rectal gland and gut, but as yet, the latter are not well characterized. Intestinal sac preparations of the Pacific spiny dogfish shark ( Squalus acanthias suckleyi ) incubated in vitro strongly reabsorbed urea from the lumen after feeding, but mucosal fluid ammonia...

... and kidney. The role of prolactin in intestinal ion transport remains little studied. In marine fish, which have high drinking rates, epithelial bicarbonate secretion in the intestine produces luminal carbonate aggregates believed to play a key role in water and ion homeostasis. The present study...

...C. K. Tipsmark; K. J. Sørensen; S. S. Madsen SUMMARY Osmotic balance in fish is maintained through the coordinated regulation of water and ion transport performed by epithelia in intestine, kidney and gill. In the current study, six aquaporin (AQP) isoforms found in Atlantic salmon ( Salmo salar...

... – ], as well as alterations in net acid or base excretion to the water following feeding. Additionally the role of the intestine in the regulation of acid–base balance during feeding was investigated with an in vitro gut sac technique. Feeding did not affect plasma glucose or urea concentrations, however...
