Plasma Renin Activity During Acute Stage of Cerebrovascular Diseases

Plasma renin activity in acute cerebrovascular disease: preliminary communication.

Plasma Renin Activity in Acute Cerebrovascular Disease: Preliminary Communication • A preliminary study of plasma renin activity was made in 22 patients with acute cerebrovascular disease. Eight of 12 patients with intracranial hemorrhage had plasma renin activity values above the normal range of 30 to 330 ng/100 ml plasma, but only one of ten patients with ischemic cerebrovascular disease had ...

Plasma renin activity in hypertensive diseases.

Plasma renin activity was determined in normotensive and hypertensive human subjects by a modification of the method of Boucher and co-workers. Simultaneous determination of plasma volume, serum electrolyte concentration and plasma renin activity was performed. The plasma renin activity was normal in essential hypertension and in pheochromocytoma, normal or subnormal in Cushing's syndrome with ...

Plasma renin activity in end-stage kidney disease.

Plasma renin activity, fluid and electrolyte balance, and hemodynamic conditions were measured in seven hypertensive patients with end-stage renal disease before and after five exchanges of peritoneal dialytic fluids which removed large amounts of water and sodium, sodium but little water, and little water and sodium, respectively. The subjects had normal plasma renin activity, severe anemia, h...

Elevation of plasma renin activity during avoidance performance in baboons.

The effect of a 3-h Sidman avoidance operant conditioning schedule (liver pressing to avoid an electric shock) on plasma renin activity and renin substrate concentration was examined in baboons (Papio cynocephalus). Plasma samples were drawn over a 24-h period on both the control and test days, and the avoidance session was presented on the morning of the test day. Plasma renin activity was sig...
