Rats were treated with a single dose of isoproterenol (25 mg/kg sc) and the levels of
polyamines determined in various parts (right ventricle, basis, medial part and apex of the …

The importance of changes in polyamine metabolism for myocardial growth was assessed
by measuring the activity of ornithine decarboxylase (ODC) and the polyamines spermidine …

Isoprenaline stimulated increases in ornithine decarboxylase activity and polyamine content
in cardiac tissues are implicated in macromolecular synthesis and cellular growth, but little is …

To evaluate the role of polyamine biosynthesis in myocardial growth, the activity of ornithine

The aliphatic amines putrescine, spermidine and spermine are natural polycations widely
distributed in prokariotic and eukariotic ceils. Although they have been known for over 300 …

Polyamine levels were measured by means of high-performance liquid chromatography in
Langendorff-perfused rat hearts subjected to the calcium paradox protocol. The …
