BACKGROUND The role of angiotensin-converting enzyme genetic polymorphisms as a predictor of echocardiographic outcomes on heart failure is yet to be established. The local profile should be identified so that the impact of those genotypes on the Brazilian population could be identified. This is the first study on exclusively non-ischemic heart failure over a follow-up longer than 5 years. OB...
While renin is a highly specific protease, converting enzyme has at least two principal substrates, angiotensin I and bradykinin. Changes in the rate of formation of angiotensin II or degradation of bradykinin can influence the hypotensive action of angiotensin converting enzyme inhibitors. The present study was designed to determine if there were differences in the maximal blood pressure reduc...
The relationship between plasma angiotensin and the reduction of blood pressure with the angiotensin converting enzyme inhibitor enalapril was studied in rats. Blood pressure was measured in conscious rats with indwelling arterial catheters. To measure angiotensin II, plasma was analyzed by physical separation of angiotensins using high performance liquid chromatography followed by radioimmunoa...
The inhibition of angiotensin converting enzyme by ramipril, ramiprilat, enalapril, enalaprilat, and captopril was studied in the plasma and various tissues (lung, heart, renal cortex, renal medulla) of normotensive rats and spontaneously hypertensive rats. Displacement curves for [3H]ramiprilat were established on each tissue with the converting enzyme inhibitors, and their potencies were expr...
1. A colorimetric method was developed for the direct chemical assay of human carboxypeptidase A (carboxypolypeptidase; EC 3.4.12.2) with angiotensin converting enzyme-like activity in serum or plasma, with the substrate analogue glycyl-L-histidylglycine and the angiotensin converting enzyme substrate angiotensin I (A-I). This method was based on the spectrophototometric determination of histid...
