alpha-Guanidinoglutaric acid (alpha-GGA) was first found in cobalt-induced epileptogenic focus tissue in the cerebral cortex of cats. We examined the effect of alpha-GGA on the electroencephalogram and on the brain 5-hydroxytryptamine (5-HT) level after intraventricular administration into rats.
Repeated administration of drugs that increase tryptaminergic neurotransmission antagonized the increase in latency to onset and the duration of postdecapitation convulsions (PDCs) induced by an acute 5-methoxy-N,N-dimethyltryptamine (5-MeODMT) injection; Zimelidine (2 X 5 mg kg-1), fluoxetine (2 X
Male Swiss-Webster mice were made physically dependent on ethanol using the ethanol vapour inhalation technique. Animals pretreated with methysergide, a known 5-hydroxytryptamine receptor blocking agent, had significantly greater alcohol-induced withdrawal convulsions than saline pretreated
The time course effects of the benzoquinolizine Ro 4-1284 on spinal cord norepinephrine (NE) and 5-hydroxytryptamine (5-HT) levels were compared to the effects of this same drug on electrically-induced spinal cord seizures. The data show that a significant decrease in spinal cord NE levels and a
Nisoxetine and desipramine (inhibitors of norepinephrine reuptake) each exerted a suppressant effect on spinal cord seizures by decreasing the duration of tonic extension. In addition, desipramine increased the duration of tonic flexion and nisoxetine decreased the total duration of seizure. In
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
The intracerebral microdialysis technique has been used to monitor extracellular levels of noradrenaline, 5-hydroxytryptamine and 5-hydroxyindoleacetic acid in the rat hippocampus in vivo in response to focal and generalized seizures induced by hippocampal kindling stimulation. In fully kindled
The influence of some noradrenergic, 5-hydroxytryptaminergic and cholinergic agents on imipramine-induced seizures were investigated in mice. DL-threo-3,4-dihydroxyphenylserine (DOPS) and pargyline significantly potentiated imipramine-induced seizures. Phentolamine and prazosin significantly
