Effect of thoracic irradiation and captopril therapy on total lung ACE activity. Lung ACE activity was measured using a spectrophotometric assay in isolated perfused lungs from rats studied 2-months after irradiation. Values (mean±sem) represent mean ACE activity in relative units of available ACE binding sites. Drug therapy groups received captopril (17 or 56 mg/kg/d) immediately or delayed 2-weeks after irradiation. Irradiation alone decreased lung ACE activity. Captopril therapy further reduced lung ACE activity. (Number of rats in individual groups indicated on the bars, * p ≤ 0.006, ^ p ≤ 0.001, difference from bold marker).
