The effects of the depletion of 5-hydroxytryptamine (5-HT) in the rat brain upon the 5-HT behavioural syndrome (ejaculatory response, abduction of hind-limbs, forepaw treading, and Straub tail) induced by 5-methoxy-N,N-dimethyltryptamine (1 mg/kg intraperitoneally) were investigated. The 5-HT depletion was produced by p-chlorophenylalanine (PCPA 2 X 200 mg/kg intraperitoneally) or by reserpine...
The effect of chronic and acute oral or intraperitoneal treatment with the antidepressant drugs, desipramine, amitriptyline, alaproclate and iprindole, upon pain thresholds in the tail flick, hot plate and shock titration tests of nociception in saline- and 5-MeODMT-treated rats was studied. Chronic desipramine treatment increased the pre-test tail flick latencies. In the saline-treated rats,...
The effect of acute administration of rats with the 5-hydroxytryptamine (5-HT) agonist drug 5-methoxy-N,N-dimethyltryptamine on the convulsions released by decapitation was examined. The postsynaptic agonist, 5-methoxy-N,N-dimethyltryptamine, prolonged the latency and duration from the 0.5 mg/kg dose upwards. Methergoline, 2.0 mg/kg intraperitoneally injected immediately prior to...
Abstract: The toxicity of chlorpromazine (CPZ) and mescaline (MCL) to mouse cerebellum and fibroblast cells was studied in vitro . CPZ proved to be more toxic than MCL to both tissues. Fibroblast celles are more sensitive than the cerebellum to both CPZ and MCL.
