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 activity was higher in the left ventricle than in the right ventricle of
the rat. Swimming exercise for 2 hours caused an increase in left ventricular but not right …

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

Ornithine decarboxylase activity in rat hearts perfused by the Langendorff technique
decreased by 50% after 1 h. Pyridoxal-5-phosphate, amino acids, cycloheximide …

Stimulation of ornithine decarboxylase (ODC) activity was examined in cultured heart cells
from neonatal rats. Fetal bovine serum had a concentration-dependent effect on ODC …

The activity of ornithine decarboxylase was monitored in situ by perfusing rat heart with (1-
14COOH)-ornithine. Infusion of isoproterenol or noradrenaline caused after 15-20 min an …

Ornithine decarboxylase(ODC) is a marker of tissue growth and development and, because
sympathetic stimulation of beta adrenergic receptors acutely increases ODC in the adult rat …

Heart ornithine decarboxylase (ODC) from isoproterenol treated rats was compared to heart
ODC from control rats. Isoproterenol administration did not significantly change Km for …

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 …

In the isolated perfused rat hearts, the activity of tissue ornithine decarboxylase gradually
decreases over 90 min. In contrast, the activity of S-adenosylmethionine decarboxylase …
