The turnover rates, rate constants and half-life values of neuronal histamine (HA) in 10 nuclei of the rat hypothalamus were estimated from the depletion of HA induced by α-fluoromethylhistidine (α-FMH: 100 mg/kg, i.p.), a specific inhibitor of histidine decarboxylase, on the presumption that α-FMH depletable HA pools represent neuronal ones. Marked variation in the HA turnover rates were observed among the hypothalamic nuclei, ranging from 5.7 to 19.5 pmole/mg protein/hr.
