A population-based study was performed in order to study the interrelationships of the
circulating components of the renin-angiotensin system during basal conditions and their …

Objective To investigate the relationship between circulating angiotensin converting enzyme
activity and arterial blood pressure in a population-based sample of 646 middle-aged …

The purpose of the present investigation was to describe the relative impact of genes and
environment on the variance of the plasma constituents of the renin angiotensin system. We …

Since only a minute proportion of total angiotensin-converting enzyme (ACE) is present in
plasma, the reliability of conventional in vitro measurements of ACE activity has been …

The activity of the anglotensin I converting enzyme was measured in 55 patients with
untreated essential hypertension, 11 patients with untreated renovascular hypertension, five …

The serum converting enzyme activity (SCEA) was measured in 86 healthy individuals
(1.44+/-0.82 u, mean+/-SD), 39 patients with essential hypertension (1.53+/-0.71 u), 7 …

An insertion/deletion (I/D) polymorphism of the angiotensin I converting enzyme gene
influences the level of serum angiotensin converting enzyme activity and has been …

The measurement of immunoreactive “angiotensin II” in plasma cannot provide an accurate
reflection of the efficacy of angiotensin-converting enzyme (ACE) inhibition because different …

Angiotensin I-converting enzyme (ACE) levels in plasma are stable in a given individual but
differ greatly among subjects. To establish the distribution of plasma ACE levels and the …

Despite the major physiologic role of angiotensin-converting enzyme (ACE), few studies
have evaluated the ideal conditions for measuring human plasma ACE activity, specifically …
