BACKGROUND Modafinil is a wake-promoting agent that provides wide ranges of neurological effects. There is evidence that it can produce antidepressant effects. This study investigated the antidepressant effect of modafinil in the tail suspension (TST) in mice. METHODS Different doses of modafinil was intraperitoneally (ip) administrated and then animals were subjected to TST and/or open field...

Isomyristicin results from myristicin isomerization and is reported to have the same biological activity as myristicin, an antidepressant. Myristicin at a specific dose causes toxicity, so it necessary study isomyristicin, which estimated myristicin. However, there has been no test related isomyristicin having antidepressant activity. Therefore, this aimed determine optimum of decrease immobili...

Agmatine is an endogenous neuromodulator that has been shown to have beneficial effects in the central nervous system, including antidepressant-like effects in animals. In this study, we investigated the ability of agmatine (0.1mg/kg, p.o.) and the conventional antidepressant fluoxetine (10mg/kg, p.o.) to reverse the behavioral effects and morphological alterations in the hippocampus of mice ex...

The compound 6o (at 0.5, 1 and 2 mg/kg, ip) with optimum log P and pA2 value, was subjected to forced swim test (FST) and tail suspension test (TST). The compound 6o significantly reduced the duration of immobility in mice without affecting the base line locomotion in actophotometer. Moreover, 6o (2 mg/kg, ip), potentiated the 5-hydroxytryptophan (5-HTP)-induced head twitch responses in mice an...

The aim of this analysis was to assess antidepressant & nootropic capacity Bougainvillea Glabra aqueous extract (BGAE). Forced swim test, tail suspension tetrabenazine mediated catalepsy ptosis models were used BGAE's efficacy in mice at doses 250 500 mg/kg orally. Morris water maze with elevated plus (EPM) test behaviour. Normal medications for function imipramine (25 mg/kg) piracetam (300...

Endothelins are peptides described initially as potent vasoactive mediators. Recently, studies reported that endothelins can modulate the production and release of cytokines by immune cells. In turn, cytokines are involved in depression disorders and also in the effectiveness of some antidepressants. Therefore, we investigated the effects of treating mice with bosentan, a mixed endothelin recep...

Post-partum depression (PPD) is a common mental disease in the perinatal period that profoundly affects mothers and their offspring. Some clinical studies have found that PPD is related to thyroid peroxidase antibodies (TPOAbs); however, the mechanism underlying this relationship is unclear. Female C57BL/6 mice immunized with adenovirus encoding the cDNA of the full-length mTPO (mTPO-Ad) were u...

The main objective of the present investigation is to explore polyherbal containing Centella asiatica, Glycerrhiza glabra, Gymnosporia montana and Cow urine for its neuroleptic properties, using the tail suspension test (TST), light dark test (LDM) and elevated plus maze (EPM) test on mice. Pharmacognostic and pharmacological study of aerial part of Centella asiatica, root of Glycerrhiza glabra...

The antidepressant-like activity of creatine in the tail suspension test (TST) was demonstrated previously by our group. In this study we investigated the involvement of the noradrenergic system in the antidepressant-like effect of creatine in the mouse TST. In the first set of experiments, creatine administered by i.c.v. route (1 μg/site) decreased the immobility time in the TST, suggesting th...

Introduction: We investigated the sexually dimorphic effects of Dextromethorphan (DM) on cognitive and depression-like behaviors as well as on hippocampal histology in rats following acute administration. Methods: Wistar rats of both sexes were treated with 25 or 50 mg/kg of DM for 7 days via intraperitoneal injection. At the end of the administration, behavioral studies were performed on the ...
