Abstract

The rotometer described here consists of a data acquisition system made of several reed relays which are activated by a small moving magnet when the animal performs rotations. The apparatus has an angular discrimination which is dependent on the number of reed relays used. A simple interface is used to normalize the pulses produced when the reed relay contacts are closed. This normalized output closes key contacts in the keyboard of a microcomputer resulting in ASCII strings. A simple BASIC program is used for computation of various turn fractions. The program also calculates the total number of movements over time, allowing the assessment of activity vs. time.

p-methylthioamphetamine is a potent new non-neurotoxic serotonin-releasing agent.

p-Methylthioamphetamine (MTA), was compared to p-chloroamphetamine (PCA) in a number of pharmacological assays. MTA was about 2-fold more potent than PCA at inhibiting synaptosomal uptake of [3H]5-hydroxytryptamine ([3H]5-HT), and about 7-fold and 10-fold less potent than PCA at inhibiting synaptosomal uptake of [3H]dopamine and [3H]norepinephrine, respectively. In drug discrimination assays, MTA was nearly equipotent to PCA in animals trained to discriminate saline from 3,4-methylenedioxymethamphetamine (MDMA), or two related analogues S-(+)-N-methyl-1-(1,3-benzodioxol-5-yl)-2-butanamine (S-MBDB) or 5-methoxy-6-methyl-2-aminoindan (MMAI). MTA caused dose-dependent increases of tritium efflux from superfused rat frontal cortex slices preloaded with [3H]5-HT, comparable to that induced by an equal molar concentration of PCA. The potential neurotoxicity of MTA was examined by measuring monoamine and metabolite levels at one week following an acute dose. A 10 mg/kg dose of PCA caused a 70-90% decrease of cortical, hippocampal and striatal 5-HT and 5-hydoxyindoleacetic acid (5-HIAA) levels, while twice the molar dose of MTA (21.3 mg/kg) had no effect. Thus, MTA is a potent, selective, serotonin releaser, apparently devoid of serotonin neurotoxic effects. This work also supports the idea that catecholamine systems may play a critical role in the neurotoxicity of PCA-like compounds.

Dextromethorphan antagonizes the acute depletion of brain serotonin by p-chloroamphetamine and H75/12 in rats.

A role for calcium in p-chloroamphetamine-induced neurotoxicity has been inferred previously from protective effects of dextromethorphan. We found that dextromethorphan reduces rat brain concentrations of 5-hydroxyindoleacetic acid and blocks the acute, non-neurotoxic depletion of brain serotonin by p-chloroamphetamine and by H75/12. Inhibition of the membrane transporter on brain serotonin neurons by dextromethorphan in vivo might explain its protective effect against p-chloroamphetamine neurotoxicity.

Regulation of collagenase gene expression by serotonin and progesterone in rat uterine smooth muscle cells.

The regulation of collagenase gene expression by serotonin and progesterone was investigated in primary cultures of rat uterine smooth muscle cells. Northern blot analysis demonstrates that serotonin (5-hydroxytryptamine (5-HT)), when administered to cells in serotonin-depleted medium, causes 6-8-fold increases in levels of collagenase mRNA. Selective serotonin 5-HT2 receptor agonists were able to mimic the effect of the natural hormone, while the induction by serotonin could be blocked by 5-HT2 receptor antagonists. Addition of phorbol ester (PMA) to 5-HT-depleted cultures fully mimicked the effect of 5-HT on collagenase mRNA induction. Treatment with progesterone analogs caused a decrease in collagenase mRNA, even in the presence of saturating levels of serotonin or PMA. In all experiments, levels of secreted collagenase were observed to correspond to levels of collagenase mRNA. Experiments with cycloheximide demonstrate that serotonin- and PMA-induced increases in collagenase mRNA are dependent on protein synthesis. Furthermore, nuclear run-on analysis shows that mRNA increases are accompanied by increases in initiation of transcripts. These data indicate that transcription of collagenase mRNA in myometrial smooth muscle cells is stimulated by serotonin, possibly via activation of protein kinase C, but is in some way prevented by the negative influence of progesterone.
