The results obtained indicated that cationic flotation of pyrochlore was not successful. Dispersant AQ4 has a pronounced effect on niobium metallurgical results. Dispersant/ depressant AQ4 is composed of the following individual reagents 60% orthodihydrox-ybenzene (Catacol), 30% low-molecular-weight acrylic acid (Accumer 2400) and 10% hexametapho sphate.

Several classes of drugs, notably the antipsychotics, discussed in Chapter 34, interfere with dopaminergic transmission. In general, dopamine appears to be an inhibitory neurotransmitter. Five dopamine receptors have been identified the most important and best studied are the Dj. and D2.receptor groups. The Dj receptor, which increases cyclic adenosine monophosphate (cAMP) by activation of adenylyl cyclase, is located primarily in the region of the putamen, nucleus accum-bens, and in the olfactory tubercle. The D2 receptor decreases cAMP, blocks certain calcium channels, and opens certain potassium channels.

Starting in 1993, reports have appeared that in rat striatum and nucleus accum-bens D2-like autoreceptors, when activated, enhanced removal of dopamine from the extracellular space by means of the dopamine transporter (DAT) as studied by voltammetry (Table2). D2 receptor activation also increased [3H]-dopamine uptake in Xenopus oocytes transfected with both the human D2 receptor and the human DAT (Mayfield and Zahniser 2001), as well as the uptake of a fluorescent DAT substrate in human embryonic kidney cells equally transfected with both the human D2 receptor and the human DAT (Bolan et al. 2007). In accord with this autoreceptor-transporter connection, clearence of dopamine from the striatal extracellular space in vivo was reduced in D2 receptor knockout mice (Dickinson et al. 1999). Unfortunately, however, the data in the literature are by no means consistent. No effect of D2 receptor activation on the DAT was observed in another rat striatum study (Prasad and Amara 2001), in synaptosomes from rat and human neocortex (Feuer-stein, unpublished observations), and in PC 12 cells that possess D2 receptors and the DAT (Pothos et al. 1998). In a second study with D2 receptor knockout mice, uptake of dopamine in the striatum was increased rather than decreased (Schmitz et al. 2002). The reason for these discrepancies is not clear. It has been suggested that the clearance measurements by means of voltammetry were not appropriate for assessment of the function of the DAT (Prasad and Amara 2001).
