The effects of zolantidine, the first brain-penetrating H2-receptor antagonist, on the brain levels of histamine (HA) and the HA metabolite tele-methylhistamine (t-MH), the activity of histamine methyltransferase (HMT) and the brain HA turnover rates were investigated in rats. Zolantidine dimaleate (0.1 to 100 mg/kg, s.c.) had no effect on whole brain(More)
Rats received intrastriatal or intranigral injections of 6-hydroxydopamine (6-OHDA) on the same side towards which they made most of their turns during a previous test of amphetamine-induced rotational behavior. One week later they were retested for amphetamine-induced rotational behavior and it was found that only approximately half of them increased their(More)
The relationship between circling behavior and the concentrations of dopamine (DA), serotonin, and their metabolites in corpus striatum was investigated in rats. We have previously reported evidence indicating that in both sexes there are two kinds, or populations, of rats: those with their turning biases directed away from (Contra greater than Ipsi rats),(More)
