Effects of alpha-fluoromethylhistidine (FMH), an irreversible inhibitor of histidine decarboxylase, on development of brain histamine and catecholamine systems in the neonatal rat.

Journal Article (Journal Article)

Daily administration of FMH to neonatal rats produced long-lasting inhibition of histidine decarboxylase in hypothalamus and cerebral cortex and led to depletion of histamine in both brain regions. The onset of depletion was more rapid in cerebral cortex, a region in which non-neurotransmitter pools of histamine predominate in early postnatal life, appearing as early as postnatal day 3; depletion in the hypothalamus, a region rich in histaminergic neuronal projections, appeared later. No effects were seen on body or brain growth, nor was development of other biogenic amine systems affected. FMH thus provides a selective probe for examining the role of histamine in brain development.
