in order to test the hypothesis that the contraction induced in human resistance arterioles by porcine tetradecapeptide renin substrate ( tdp ) is mediated by enzymes specific to the renin-angiotensin cascade , human resistance vessels from skin and subcutaneous fat were mounted in a myograph and exposed to tdp in the presence and absence of the human renin inhibitor h261 , the serine protease inhibitor aprotinin , a polyclonal anti-human renin antibody and captopril .
