[1-Sarcosine, 8-Isoleucine] angiotensin II was given to 8 patients with cirrhosis and ascites and 7 cirrhotic patients without ascites on a regular diet. The 3 ascitic patients with high plasma renin activity (PRA) gave a depressor response, but the other ascite patients with normal or low PRA gave a pressor response or no response. All the non-ascitic patients gave a pressor response. There was an inverse correlation between the PRA before infusion and the change in blood pressure induced by this compound. In the patient with the highest PRA, who had ascites of a few days' duration, a marked reduction in blood pressure was observed on infusion of this compound. These results suggest that the renin-angiotensin system might be involved in maintenance of a normal blood pressure in some patients with cirrhosis and ascites, whose ascites is presumably in an early stage.

D008103 Liver Cirrhosis Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules. Cirrhosis, Liver,Fibrosis, Liver,Hepatic Cirrhosis,Liver Fibrosis,Cirrhosis, Hepatic
D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.

D000450 Aldosterone A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium. Aldosterone, (+-)-Isomer,Aldosterone, (11 beta,17 alpha)-Isomer
D000804 Angiotensin II An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.

D001201 Ascites Accumulation or retention of free fluid within the peritoneal cavity.
