TL;DR

Histochemical studies showed that the administration of lithium and H44/68 together led to a stronger reduction in fluorescence intensity of the noradrenaline neuron terminals in the brain than that seen after H 44/68 alone.

Abstract

Lithium, administered intraperitoneally to rats in doses of 2.5 to 15 meq/kg body wt., did not alter the noradrenaline content of the brain; but when given together with a tyrosine-hydroxylase inhibitor, H 44/68, it produced a depletion of brain noradrenaline which was more pronounced than that produced by H 44/68 alone. The effect of lithium on cerebral noradrenaline depletion appeared to be correlated with the lithium concentration in the brain tissue. Histochemical studies also showed that the administration of lithium and H 44/68 together led to a stronger reduction in fluorescence intensity of the noradrenaline neuron terminals in the brain than that seen after H 44/68 alone. Lithium did not affect the depletion of dopamine produced by H 44/68 or the depletion of 5-hydroxytryptamine produced by the tryptophanhydroxylase inhibitor H 22/54.
