title: The effect of hepatic ischemia-reperfusion on polyamine metabolism in some organs of the rat.
abstract: Hepatic ischemia was produced by clamping the portal venous and hepatic arterial blood supply to the left lateral and median lobes of the rat liver. Hepatic ornithine decarboxylase (ODC) and spermidine/spermine N1-acetyltransferase (SAT) activities in ischemic and nonischemic regions were increased and, respectively, peaked by 6 hr and 3 hr after 1 hr of hepatic ischemia. Hepatic putrescine contents in ischemic and nonischemic regions were increased and peaked by 6 hr. However, hepatic spermidine and spermine were not increased. an increase in ODC activity was also observed in the spleen and the kidney after 1 hr of hepatic ischemia. [3H]thymidine incorporation into DNA was observed in the liver and the spleen--however it was not observed in the kidney--after hepatic ischemia.
