Lack of renal effects of DOCA, ACTH, spironolactone, and angiotensin II in Squalus acanthias

Abstract Angiotensin II was infused intravenously in spiny dogfish sharks ( Squalus acanthias ). There were no significant effects on arterial blood pressure, glomerular filtration rate, urine flow, or Na excretion either in comparison with pre‐ and postinfusion values or in comparison with values m...

Description
Summary:Abstract Angiotensin II was infused intravenously in spiny dogfish sharks ( Squalus acanthias ). There were no significant effects on arterial blood pressure, glomerular filtration rate, urine flow, or Na excretion either in comparison with pre‐ and postinfusion values or in comparison with values measured in a control group of fish given elasmobranch saline intravenously. In other dogfish, glomerular filtration rate, urine flow, and Na and K excretory rates were measured for 3 days following implantation of desoxycorticosterone (DOCA), adrenocorticotropin (ACTH), or spironolactone; a control group was given no drug. There were no significant differences between these four groups of fish with respect to any of the measured parameters. These results suggest that the dogfish kidney is not a target organ for several substances known to affect renal function, either directly or indirectly, in other animals.
