Purification and Identification of Angiotensin I-Converting Enzyme Inhibitor from Morokheiya (Corchorus olitorius).

Angiotensin-converting Enzyme Inhibitor

The hemodynamic effects of an oral angiotensin-converting enzyme inhibitor, captopril, were evaluated in 10 symptomatic patients with chronic congestive heart failure. In all patients there was a significant increase in cardiac output (average 28%), stroke volume (49%), and stroke work index (26%), along with a decrease in pulmonary capillary wedge pressure (48%), indicating improved left ventr...

Angiotensin-converting Enzyme Inhibitor

The effects of angiotensin-converting enzyme inhibitor (CEI) SQ14225 on infarct size and regional myocardial blood flow were studied in 21 anesthetized dogs subjected to 6 hours of coronary occlusion. An area of myocardium at risk of necrosis was determined in vivo after 15 minutes of coronary occlusion but before CEI treatment (AR1) using an autoradiographic technique and after treatment after...

Angiotensin Converting Enzyme in Sarcoidosis

Angiotensin I converting enzyme.

• Interest in particular biologically active substances waxes and wanes. Investigators rush into a newly opened field, solve a few problems, and frequently raise more; then they rush out to follow more promising developments elsewhere. However, interest in angiotensins generally has persisted and increased. Observation of the actions of angiotensins has led to the study of enzymes involved in t...

Purification and properties of angiotensin-converting enzyme from hog lung.

Angiotensin-converting enzyme was purified 1500-fold from a homogenate of hog lungs. The purification procedure included fractionation with ammonium sulfate, inactivation of contaminating enzymes at pH 4.7, batch treatment with CM-cellulose, and chromatography on columns of DEAE-cellulose, hydroxyapatite, and Sephadex G-200. The enzyme was assayed with hippurylglycylglycine and, after pH 4.7 wa...
