Antidepressant-like activity of magnesium in forced swim test (FST) was demonstrated previously. Also, enhancement of such activity by joint administration of magnesium and antidepressants was shown. However, the mechanism(s) involved in such activity remain to be established. In the present study we examined the involvement of NMDA/glutamate pathway in the(More)
Recent preclinical data indicated the antidepressant-like activity of zinc in different tests and models of depression. The present study investigates the involvement of the serotonergic system in zinc activity in the forced swim test (FST) in mice and rats. The combined treatment of sub-effective doses of zinc (hydroaspartate, 2.5 mg Zn/kg) and citalopram(More)
The use of benzodiazepines (BDZs) in the long-term treatment of epilepsy is greatly restricted by their capacity to induce tolerance and dependence. Thus, the development of new BDZ-related therapeutic agents should be directed by strategies that minimize tolerance- and dependence-inducing properties. Experimental procedures used to determine the success of(More)
Both clinical and preclinical studies demonstrate the antidepressant activity of the functional NMDA receptor antagonists. In this study, we assessed the effects of two glycine/NMDA receptor ligands, namely L-701,324 (antagonist) and D: -cycloserine (a partial agonist) on the action of antidepressant drugs with different pharmacological profiles in the(More)
Zinc and magnesium are potent inhibitors of the N-methyl-D-aspartate (NMDA) receptor complex. Recent data demonstrate that both zinc and magnesium, like other NMDA receptor antagonists, exhibit antidepressant-like activity in rodent screening tests and depression models. In the present study, we investigated the effect of D-serine (agonist for the(More)
Altered function of neuronal nicotinic acetylcholine receptors in the brain has recently been associated with an idiopathic form of partial epilepsy, suggesting that functional alterations of these receptors can be involved in the processes leading to epileptic seizures. Thus, nicotinic acetylcholine receptors may form a novel target for antiepileptic drug(More)
The antidepressant- and anxiolytic-like effects of magnesium, an N-methyl-d-aspartate (NMDA) glutamate receptor inhibitor, were studied in mice using the forced swim test and elevated plus-maze test, respectively. The doses of 20 and 30 mg Mg/kg, reduced immobility time in the forced swim test exerting antidepressant-like activity. In the elevated plus-maze(More)
Antidepressant-like activity of zinc in the forced swim test (FST) was demonstrated previously. Enhancement of such activity by joint administration of zinc and antidepressants was also shown. However, mechanisms involved in this activity have not yet been established. The present study examined the involvement of the NMDA and AMPA receptors in zinc(More)
The anxiolytic-like activity of magnesium in mice during the elevated plus maze (EPM) has been demonstrated previously. In the present study, we examined the involvement of NMDA/glutamate receptor ligands on the magnesium effect on the EPM. We demonstrated that low, ineffective doses of NMDA antagonists (the competitive NMDA antagonist CGP 37849, 0.3 mg/kg;(More)
Previously, we demonstrated antidepressant-like effect of magnesium (Mg) in the forced swim test (FST). Moreover, the joint administration of Mg and imipramine (IMI) at ineffective doses per se, resulted in a potent reduction in the immobility time in this test. In the present study, we examined the effect of immobility stress (IS), and Mg and/or IMI(More)
