1 To assess metabolic functions of the pulmonary circulation during lung injury and subsequent recovery from injury, we measured angiotensin-converting enzyme (ACE) activity by means of benzoyl-phenylalanyl-alanyl-proline (BPAP) hydrolysis and 5-hydroxytryptamine (5-HT) removal in vivo in three groups of anesthetized rabbits. benzoylphenylalanyl-alanyl-proline angiotensin-converting enzyme Oryctolagus cuniculus

5 Decreased Vmax/Km for ACE was due to a significant reduction in apparent Vmax for BPAP (control = 235 +/- 37, PMA = 139 +/- 12 nmol/s). benzoylphenylalanyl-alanyl-proline angiotensin-converting enzyme Oryctolagus cuniculus
6 We conclude that repeated exposure of rabbits to PMA results in lung injury manifested as depressed pulmonary ACE activity and pulmonary artery hypertension. Tetradecanoylphorbol Acetate angiotensin-converting enzyme Oryctolagus cuniculus
