The temporal blood pressure course and the diurnal profile of the renin–angiotensin system
were examined in 13 patients with essential hypertension receiving hydrochlorothiazide and …

Serum angiotensin-converting enzyme (SACE) was significantly elevated in 16 of 48
patients with various types of chronic renal disease not on hemodialysis [45.6±(SD) 16.7 …

We investigated the alteration of the ACE in different parts of the circulation in 21 patients
with essential hypertension, who suffered from angina pectoris attacks. Blood samples were …

With chronic angiotensin converting enzyme (ACE) inhibition, blood pressure remains
controlled throughout the day despite intermittent recovery of normal function of the renin …

We have evaluated a recently introduced colour test kit for the determination of serum
angiotensin I-converting enzyme catalytic activity. p-Hydroxyhippuric acid, liberated from p …

Measurement of plasma renin activity is widely used as an indirect assessment of plasma
angiotensin II concentration. There has been some controversy over the validity of this assay …

Background Angiotensin II (Ang II) levels are normally very low in human plasma,
approximately 5 pg/ml. They are usually measured by radioimmunoassay after extraction …

A very simple, fast, and sensitive RIA of angiotensin (Ang) II has been developed, based on
a monoclonal antibody with high affinity and specificity, making possible the direct …

Active and total plasma renin concentration, as well as plasma angiotensin II, aldosterone
and renin substrate concentrations were measured in venous blood samples from 17 normal …

We report here the alterations of serum angiotensin-converting enzyme activity (S-ACE) and
of active renin plasma concentrations (ARPC) in 41 insulin-dependent diabetes mellitus …
