Serotonin was determined in platelets of 140 patients with idiopathic mal seizures. According to anticonvulsive therapy these patients were divided into the following five groups: no medication, Diphenylhydantoin, Diphenylhydantoin calcium, Primidon, and combination of various of the anticonvulsants
This ongoing column is dedicated to the challenging clinical interface between psychiatry and primary care-two fields that are inexorably linked.Tramadol (Ultram(®)) is a commonly prescribed analgesic because of its relatively lower risk of addiction and better safety profile in comparison with
Prostaglandins (PGs) of the E series are known to exert anticonvulsant action in experimental animals. Earlier studies from this laboratory have indicated that PGE1 inhibits pentylenetetrazole (PTZ)-induced convulsions in rats through a serotonin-mediated mechanism. PGD2, the major PG in the rodent
Intraventricular injection of 5,7-dihydroxytryptamine, selective destruction of descending serotoninergic neurons by 5,6-dihydroxytryptamine or electrolytic and chemical lesions of the nucleus raphe dorsalis did not affect the electroconvulsive threshold in rats. No effect was observed after the
Selective blockade of anandamide hydrolysis, through the inhibition of the FAAH enzyme, has anticonvulsant effects, which are mediated by CB1 receptors. Anandamide, however, also activates TRPV1 channels, generally with an opposite outcome on neuronal modulation. Thus, we suggested that the dual
5,7-Dihydroxytryptamine (5,7-DHT) injections which caused selective depletion of serotonin in the forebrain enhanced the seizures caused by pentylenetetrazol (PTZ 90 mg/kg s.c.) in rats. No effect was observed in rats with 5,7-DHT-induced depletion of spinal serotonin or treated with metergoline (1
OBJECTIVE
Curcumin, derived from turmeric, has been demonstrated to be effective in controlling seizures, although the exact mechanism is yet unknown. In this study, the role of serotonin and its receptors in the anticonvulsant effect of curcumin was evaluated in mice.
METHODS
Total 110 mice were
The neuropeptide galanin suppresses seizure activity in the hippocampus by inhibiting glutamatergic neurotransmission. Galanin may also modulate limbic seizures through interaction with other neurotransmitters in neuronal populations that project to the hippocampus. We examined the role of galanin
Investigations were carried out in two groups of male rats: a group susceptible to audiogenic convulsions and a control group. The following parameters were determined under basal conditions and 24 and 48 hours after intraperitoneal administration of a single lithium carbonate dose (0.67
BACKGROUND
Desvenlafaxine is used to treat major depression. Desvenlafaxine is also the active metabolite of venlafaxine. Venlafaxine overdose can cause serotonin toxicity, seizures and cardiovascular effects, but there is limited information on desvenlafaxine overdose.
OBJECTIVE
We aimed at
OBJECTIVE
To investigate the relationship between serotonin (5-HT) and epilepsy and the mechanism of learning-memory in pilocarpine (PILO)-induced epileptic rats after 5,7-dihydroxytryptamine (5,7-DHT) microinjection in median raphe nucleus.
METHODS
Adult S D rats were randomly divided into 3
5-Hydroxytryptophan (5-HTP) reduced the intensity of both audiogenic and pentylenetrazol seizures. p-Chlorophenylalanine reduced audiogenic seizure (AGS) susceptibility but failed to change the pentylenetetrazol seizure (PTS). Drugs blocking brain serotonin (5-HT) receptors suppressed AGS but caused
The main objective of this study was to determine the modifications induced by the pesticide lindane (gamma-hexachlorocyclohexane) in the regional concentration of neurotransmitters in brain, taking the tonic-clonic seizure as the main sign of its neurotoxic action. The animals were given lindane
Cerebral intraventricular injections of 17 and 50 microgram magnesium in artificial cerebrospinal fluid progressively depressed the Non-specific Excitability Level of permanently cannulated 150--200 g rats fed a low magnesium diet for 21 days. Compared with control diet, a low Mg diet caused an
The present study examined whether the inhibition of serotonin transporters (SERT) contributes to cocaine- and other local anesthetics-induced convulsions, and which subtypes of 5-HT receptor are involved in the convulsions. For this purpose, cocaine, meprylcaine and lidocaine, all of which have
