    Notes: Abstract Prussian blue and its analogs bonded to poly(vinylamine hydrochloride) (PVAm · HCl) containing FeII or FeIII and M2+ (M=Fe, Co, Cu) in a 1∶1 molar ratio were obtained by the reaction of [Fe(CN)6] n− (n=3,4) with M2+ ion-PVAm · HCl mixture in aqueous solution. Under a limited polymer concentration (TVAm/TFe over 10), these polymer complexes thus obtained were stable and soluble in water. By casting these solutions, colored films can be produced. The formation of Prussian blue and its analogs bonded to PVAm · HCl was also investigated by the Benesi-Hildebrand method. The molar extinction coefficients of intervalence charge transfer (FeII→FeIII, CoII→FeIII, FeII→CuII) band for MFe(CN)6](n−2)− bound to PVAm · HCl (M=Fe, Co, Cu) were found to be 10,100−9601 · mol−1 · cm−1 at 25

    Differential effects of haloperidol, clozapine, and fluperlapine on tuberoinfundibular dopamine neurons and prolactin secretion in the rat (1987)

    Notes: Summary Two atypical neuroleptic agents, clozapine and fluperlapine, produced rapid elevations in plasma PRL concentrations that were similar in magnitude to those produced by haloperidol. However, the PRL response to clozapine or fluperlapine was of much shorter duration than that elicited by haloperidol. Clozapine, but neither fluperlapine nor haloperidol, produced a rapid increase in the activity of tuberoinfundibular dopamine (TIDA) neurons, as evidenced by an enhanced accumulation of dihydroxyphenylalanine (DOPA) in the median eminence after the inhibition of DOPA decarboxylase. The clozapine-induced increase in DOPA accumulation was evident within 30 minutes after its administration and persisted for at least 4 hours. The clozapine-induced increase in the activity of TIDA neurons may account, in part, for the abbreviated PRL response to this neuroleptic. In addition, ability to produce a short-lived increase in PRL secretion in the rat appears to be common to the atypicl neuroleptic drugs.

    Activity of tuberoinfundibular dopaminergic neurons and concentrations of serum prolactin in the rat following lithium administration (1988)

    Notes: Abstract Maintenance of rats on a lithium-containing diet for 3–21 days resulted in a suppression of prolactin (PRL) secretion in vivo and in vitro. Lithium treatment also resulted in an increase in the activity of tuberoinfundibular dopaminergic neurons, as evidenced by an increased accumulation of dihydroxyphenylalanine (DOPA) in the median eminence after inhibition of DOPA decarboxylase and an increased concentration of dopamine in the anterior pituitary gland. The accumulation of DOPA in the neurointer-mediate lobe of the pituitary gland, the prefrontal cortex, the striatum and the nucleus accumbens was also enhanced by lithium treatment. It is concluded that lithium treatment enhances the synthesis of dopamine in many brain regions and that an increased activity of tuberoinfundibular dopaminergic neurons results in an enhanced inhibitory control of PRL secretion.
