Abstract

The presence of components of a renin-angiotensin system was investigated in the heart of an African lungfish Protopterus annectens. A renin-like activity is present in heart homogenates. The activity reaches its maximum after 90 min of incubation at 20°C. By a spectrophotometric assay, an angiotensin converting enzyme-like activity was detected. By immunohistochemistry Ile⁵-Angiotensin II immunoreactive cardiocytes were demonstrated in the atrium and bulbus. Our data indicate that probably a local renin-angiotensin-like system is present in the heart of Protopterus annectens.
