1. The levels of plasma renin activity or concentration and plasma angiotensin were similar
in normotensive subjects and in untreated or treated essential hypertensives. 2. There was a …

For human samples quantitation of inactive renin can be carried out by incubation with
trypsin under defined conditions, followed by RIA of the activated renin. for dog samples we …

It has previously been suggested that in addition to renin and renin substrate concentrations,
other factors in plasma may also influence the rate of angiotensin production. The present …

The biological significance of active and inactive renin was investigated by comparison of an
in-vitro assay of active, total and inactive plasma renin concentration (PRC), plasma renin …

1. Plasma renin activity and circulating amounts of blood angiotensin II were measured in
twenty-six patients with uncomplicated essential hypertension. 2. Measurements were made …

Renin activity, concentration, substrate and reactivity were determined in normal subjects as
well as in hypertensive subjects with suppressed and normal plasma renin activity. Renin …

1. In plasma samples from normal subjects and patients with untreated essential
hypertension, the concentration of inactive renin (as measured after acidification) was on …

Pentobarbitone-anesthetized cats underwent peritoneal dialysis and had blood samples
removed and kidneys deep frozen at sacrifice. Inactive renin is easily measurable in cat …

Normal human plasma contains an active form of renin that is activated by acidification to pH
3.0 and comprises 56% of the total renin. In our study, inactive renin was also present in …

A positive correlation between blood pressure and renin substrate concentration is found in
a wide variety of conditions in human beings and in animal experiments. The evidence …
