the significance of active and inactive renin was investigated by comparison of an in vitro assay of active , total and inactive plasma renin concentration ( aprc , tprc , iprc ) and plasma angiotensin ii concentration ( pa ii ) with an in vivo change in mean arterial pressure ( map ) produced by angiotensin antagonism with saralasin and by angiotensin converting enzyme blockade with captopril .
