Effects of angiotensin II and C-type natriuretic peptide on the in situ perfused trunk preparation of the dogfish, Scyliorhinus canicula

Antidiuretic action of angiotensin II in the river lamprey Lampetra fluviatilis: evidence for endocrine control of kidney function in cyclostomes

“…The measurements of urine osmolality in L. fluviatilis during infusion of Ang II did not indicate any change in water reabsorption by kidney tubules, as has been described for teleosts but not elasmobranchs (Brown et al , 1980; Wells et al , 2006). In L. fluviatilis , however, a more comprehensive analysis of the role of the RAS in the renal tubular handling of water and electrolytes has yet to be undertaken.…”

“…obs.). A similar but more pronounced antidiuretic action of Ang II has been observed in the dogfish Scyliorhinus canicula (L.) and O. mykiss (Gray & Brown, 1985; Wells et al , 2006). The present study, however, is the first evidence for an antidiuretic action in cyclostomes and suggests that regulation of renal function by the RAS may have developed early in vertebrate evolution.…”
