The renin angiotensin aldosterone concatenation, via two effector components, angiotensin
II and aldosterone, simultaneously regulates (1) body sodium and water content,(2) arterial …

The angiotensin I converting enzyme has two important functions: it inactivates bradykinin
and converts angiotensin I to angiotensin II. Inhibition of the enzyme blocks the renin …

An adenyl cyclase activated by low concentrations of dopamine has been found in the
mammalian superior cervical sympathetic ganglion. The existence of this enzyme may …

in the vascular endothelium of rabbit lung, liver, adrenal cortex, pancreas, kidney, and …

• Interest in particular biologically active substances waxes and wanes. Investigators rush
into a newly opened field, solve a few problems, and frequently raise more; then they rush …

Antibody to angiotensin II, or a specific peptide competitive inhibitor of angiotensin II, was
used to investigate the role of the renin-angiotensin system in two types of renal …

Seven synthetic peptides, identical to those found in the venom of Bothrops jararaca,
inhibited the peptidolytic activity of homogeneous (275-fold purified) angiotensin-converting …

Non-enzymatic proteins from snake venoms play important roles in the immobilization of

The antihypertensive action of nonapeptide competitive inhibitor of angiotensin-1-converting
enzyme was evaluated in 13 hypertensive patients. In 12 a single injection (1 to 4 mg per …

The renin-angiotensin system has an important role in maintaining elevated blood pressure
levels in certain forms of experimental and human hypertension. Renin, an enzyme …
