β¦ Synopsis
We have reported previously that angiotensin I1 increases urine flow and Na and K excretion rates in the aglomerular goosefish Lophius americanus. The present experiments were undertaken to determine if antagonism of endogenous angiotensin has the opposite renal effects. Arterial blood pressure, urine flow, and plasma and urine electrolytes were measured during two consecutive clearance periods in two groups of goosefish. The control group (n = 7) received saline intravenously during both periods; the experimental group (n = 8) received saline during the first period and a competitive antagonist of angiotensin I1 (saralasin, or [Sarl, Val5, Alas] angiotension 11) dissolved

## Abstract The synthesis of [Sar^1^, Val^5^, (4β²βazidoβ3β²,5β²βditritio)Phe^8^] angiotensin II from a iodinated precursor peptide is described. The principal problems of this synthesis and their resolution are discussed: (i) The Ξ²βinduced autophotolysis of the highly tritiated (73 Ci/mmol) and photo
