title: The elevation of cyclic GMP as a response to acute hypervolemia is blocked by a monoclonal antibody directed against atrial natriuretic peptides.
abstract: Substantial volume expansion in conscious rats induces a strong diuresis and natriuresis that is caused by the increase in plasma levels of atrial natriuretic peptides (ANP) as measured by a radioimmunoassay. This renal response could be blocked by monoclonal antibodies directed against ANP. Parallel to the change in ANP, the cyclic GMP levels in plasma, urine and kidney tissue were increased after volume loading and reduced after additionally given antibodies. From this study it seems to be clear that the cyclic GMP rise is not a direct effect of volume expansion but is specifically mediated by the released ANP.
