Inhibition of tissue angiotensin converting enzyme. Quantitation by autoradiography.

Inhibition of tissue angiotensin converting enzyme. Quantitation by autoradiography.

Inhibition of angiotensin converting enzyme (ACE) in serum and tissues of rats was studied after administration of lisinopril, an ACE inhibitor. Tissue ACE was assessed by quantitative in vitro autoradiography using the ACE inhibitor [125I]351A, as a ligand, and serum ACE was measured by a fluorimetric method. Following oral administration of lisinopril (10 mg/kg), serum ACE activity was acutel...

Role of Tissue Angiotensin-Converting Enzyme Inhibition

Background Chronic treatment with high doses of angiotensin-converting enzyme (ACE) inhibitors prolongs survival after myocardial infarction. Since the plasma reninangiotensin system (RAS) is not consistently activated in the chronic phase after myocardial infarction, the beneficial effects of ACE inhibition have been attributed, in part, to inhibition of an activated tissue RAS. However, a rel...

Angiotensin Converting Enzyme in Sarcoidosis

Angiotensin-converting enzyme inhibition by Brazilian plants.

The potential antihypertensive activity of Brazilian plants was evaluated in vitro by its ability to inhibit the angiotensin-converting enzyme (ACE). Forty-four plants belonging to 30 families were investigated. Plants were selected based on their popular use as antihypertensive and/or diuretics. The following plants presented significant ACE inhibition rates: Calophyllum brasiliense, Combretum...

Antisense oligodeoxynucleotide inhibition of vascular angiotensin-converting enzyme expression attenuates neointimal formation: evidence for tissue angiotensin-converting enzyme function.

It has been proposed that vascular angiotensin-converting enzyme (ACE) plays an important role in regulating vascular growth. Indeed, ACE inhibitors have been reported to prevent neointimal formation after vascular injury in a rat carotid artery model. However, classic pharmacological experiments cannot exclude the potential contributions of hemodynamics and the circulating renin-angiotensin sy...
