Ornithine decarboxylase (ODC) initiates the synthesis of polyamines which play key roles in regulation of cellular development. Intracisternal administration of histamine or norepinephrine to developing rats produced age-dependent stimulation of ODC in brain. In cerebral cortex and ponsmedulla, stimulation by norepinephrine was demonstrable at postnatal day 7 and maximum stimulation occurred at about day 9. In contrast, cerebellum showed no initial reactivity to norepinephrine but still developed a large peak of response capability by day 9. In all 3 regions, the response declined rapidly thereafter during the period of major synaptogenesis of noradrenergic pathways. With histamine, none of the regions displayed ODC reactivity at 7 days postnatally; stimulation appeared by day 9, peaked at about day 11 and then declined rapidly. Thus, the trophic effect of histamine or norepinephrine toward ODC activity is present or develops postnatally and appears to terminate with synaptogenesis and onset of neurotransmitter properties of the amines.
