Two research groups in both North and South America independently discovered that renin released a novel vasopressor agent. The Argentine group named it hypertensin, and called its plasma protein substrate hypertensinogen. The group from the United States named it angiotonin. In 1958, Braun Menendez and Irvine Page suggested that the peptide should be named(More)
In this study we demonstrate that carboxypeptidase A (CPA)-like enzyme is expressed in rat kidney. The major metabolites of angiotensin (Ang) I by the rat renal mesangial cell extract at 37 degrees C, pH 7.4, were Ang 1-9 and Ang II. Quinaprilat did not influence the formation of Ang 1-9, but it inhibited formation of Ang II. The formation of Ang 1-9 was(More)
Angiotensin I-converting enzyme (ACE/kininase II) inhibitors potentiated guinea pig ileum's isotonic contractions to bradykinin (BK) and its analogues, shifting the BK dose-response curve to the left. ACE inhibitors added at the peak of the contraction immediately enhanced it further (343 +/- 40%), although the ileum inactivated BK slowly (t(1/2) = 12-16(More)
Formation of metabolites from angiotensin I that passed the coronary vessels in the isolated working rat hearts of normal and streptozotocin-induced diabetes was evaluated. HPLC analysis showed that the levels of angiotensin II and angiotensin 1-7 were unaltered in the diabetic hearts, but the perfusates of the diabetic hearts contained smaller amounts of(More)
Great scientific discoveries rarely originate from small and poor countries. However, the lives and achievements of three Yugoslav scientists who were active in the biomedical sciences, Laza K. Lazarević (1851-1891), Ivan Djaja (1884-1957), and Pavao Stern (1913-1976), serve as an example of success in this environment. These scientists, as well as the(More)
