Abstract/OtherAbstract:
Hyperthermia produced a decrease of ornithine decarboxylase activity in different tissues of adult rats. The fall in ornithine decarboxylase was dependent on time of exposure and temperature. The decay of ornithine decarboxylase activity in liver, brain, kidney, heart, spleen and testes was rather similar. The t1/2 for liver ornithine decarboxylase determined by the hyperthermic treatment (40 degrees ambient temperature) was 20 min. Ornithine decarboxylase activity was recovered in all tissues exposed to the hyperthermic shock after a period of 4 hours, although the degree of recovery was dependent on the type of tissue. The effect that hyperthermia produces on ornithine decarboxylase activity in rats could be related to an inhibition in the synthesis of active enzyme rather than to a specific degradation or inactivation of ornithine decarboxylase molecule.
