Abstract: Administration of a single dose of the recreationally used drug 3, 4‐methylenedioxyethamphetamine (MDEA or “eve”) to Dark Agouti rats resulted in an acute dose‐dependent hyperthermic response. The peak effect and duration of hyperthermia of a dose of MDEA of 35 mg/kg intraperitoneally was similar to a dose of 3, 4‐methylenedioxymetham‐phetamine (MDMA or “ecstasy”) of 15 mg/kg...

We have previously shown that the non-specific nitric oxide synthase inhibitor L-NAME blocks the behavioural effects of phencyclidine, but not d-amphetamine. To characterise the specificity of these effects, we used the specific neuronal nitric oxide synthase inhibitor AR-R 17477 in two rat models of psychosis: the prepulse inhibition of the acoustic startle response and locomotor activity. In...

Phencyclidine induces a model psychosis which can persist for prolonged periods and presents a strong drug model of schizophrenia. When given continuously for several days to rats, phencyclidine and other N-methyl-D-aspartate (NMDA) antagonists induce neural degeneration in a variety of limbic structures, including retrosplenial cortex, hippocampus, septohippocampal projections, and piriform...

Abstract: This study examined some acute pharmacological and toxicological effects of 3,4 methylenedioxymethamphetamine (MDMA, “Ecstasy”) over a range of doses (20, 40, 80, 160 and 320 mg/kg orally) in adult female rats. Deaths were observed from the 40 mg/kg MDMA group onwards. Reductions in body weight change, food and water intake were found in the 80 mg/kg group, whilst food intake alone...

The ability of various compounds to antagonise the 5-MeODMT induced prolongations of latency and duration of postdecapitation convulsions (PDCs) were compared. The 5-hydroxytryptamine (5-HT) receptor antagonists, mianserin, methergoline, cinanserin and methysergide antagonised the 5-MeODMT (0.5 to 4.0 mg/kg) induced prolongations of latency to onset of convulsions substantially and to a lesser...
