1 Uptake of N-[1 (S)-carboxy-(4-OH-3-125I-phenyl)ethyl]-L-Ala-L-Pro, an inhibitor of angiotensin-converting enzyme by rabbit lungs in situ. n-[1 (s)-carboxy-(4-oh-3-125i-phenyl)ethyl]-l-ala-l-pro angiotensin-converting enzyme Oryctolagus cuniculus
2 In 13 of 21 lungs used, a synthetic substrate for ACE, [3H]benzoyl-phenylalanyl-alanyl-proline (BPAP), was added to the bolus and appearance of its hydrolysis product, [3H]benzoyl-Phe, measured in effluent samples. bpap angiotensin-converting enzyme Oryctolagus cuniculus
3 In 13 of 21 lungs used, a synthetic substrate for ACE, [3H]benzoyl-phenylalanyl-alanyl-proline (BPAP), was added to the bolus and appearance of its hydrolysis product, [3H]benzoyl-Phe, measured in effluent samples. [3h]benzoyl-phe angiotensin-converting enzyme Oryctolagus cuniculus
4 Coadministration of the ACE inhibitor, captopril (3, 6, 8 and 28 nmol), also caused dose-dependent, reversible depression of both E(CPAP) and M(BPAP). Captopril angiotensin-converting enzyme Oryctolagus cuniculus
5 Coadministration of the ACE inhibitor, captopril (3, 6, 8 and 28 nmol), also caused dose-dependent, reversible depression of both E(CPAP) and M(BPAP). cpap angiotensin-converting enzyme Oryctolagus cuniculus
6 Coadministration of the ACE inhibitor, captopril (3, 6, 8 and 28 nmol), also caused dose-dependent, reversible depression of both E(CPAP) and M(BPAP). bpap angiotensin-converting enzyme Oryctolagus cuniculus
7 Inasmuch as CPAP inhibits ACE activity (as reflected by BPAP metabolism) and CPAP uptake is inhibited by captopril (which also inhibits BPAP hydrolysis), it appears that a large portion of this saturable process probably reflects binding to vascular ACE. cpap angiotensin-converting enzyme Oryctolagus cuniculus
