The interaction between beta and alpha adrenergic agonists on regulation of cockerel aortic
ornithine decarboxylase (ODC) activity was examined. The beta adrenergic agonist …

Adult male rats were injected either with α-or ß-adrenergic agonists and/or antagonists and
ornithine decarboxylase (ODC) activity in the heart and aorta was measured 4 hours later. At …

1. The effect of a single administration of catecholamines on ornithine decarboxylase activity
and polyamine biosynthesis in the rat spleen was investigated. 2. Isoproterenol elicited a …

The role of polyamines in modulating cultivated arterial smooth muscle cells from contractile
to synthetic phenotype was studied by biochemical and electron microscopic methods …

The pharmacological characteristics of the myocardial adrenoceptor of the mouse have
been examined during embryogenesis by measuring ornithine decarboxylase (ODC, EC …

Ornithine decarboxylase (ODC) activity, the rate-limiting step in the synthesis of polyamines,
can be demonstrated in cultured, bovine, aortic endothelial cells (EC). Serum, serotonin and …

Previous studies from our own and other laboratories have shown that hypertension induces
changes in the growth of arterial smooth muscle cells (SMC). The purpose of this study was …

Ornithine decarboxylase activity in rat heart was increased significantly by the injection of l-
norepinephrine or nisoxetine, an inhibitor of norepinephrine uptake. The enzyme was also …

Ornithine decarboxylase, a possible rate-limiting enzyme in the synthesis of polyamines,
was assayed in hearts of normal rats, sham-operated rats, and rats subjected to aortic …

Objective: The aims were to investigate the requirement for and regulation of cellular
polyamines during vascular endothelial cell proliferation. Methods: Proliferation of cultured …
