Ursolic acid, a constituent from Rosmarinus officinalis, is a triterpenoid compound which has been extensively known for its anticancer and antioxidant properties. In the present study, we investigated the antidepressant-like effect of ursolic acid isolated from this plant in two predictive tests of antidepressant property, the tail suspension test (TST) and the forced swimming test (FST) in mi...

OBJECTIVES Hibiscus (H.) esculentus L. (Okra) is distributed from Africa to Asia, Southern European and America and widely used as food. The aim of present study was to investigate antidepressant activity of Okra seeds and leaves. MATERIALS AND METHODS Antidepressant activity of methanolic extracts were evaluated by forced swimming test (FST) and tail suspension tests (TST). Also, total pheno...

This study investigated the effect of melatonin in the mouse tail suspension test (TST), and the contribution of N-methyl-D-aspartate (NMDA) receptors and the L-arginine-nitric oxide (NO) pathway to its antidepressant-like effect. The immobility time in the TST was reduced by melatonin given either by intraperitoneal (0.1-30 mg/kg) or intracerebroventricular (0.001-0.1 nmol/site) route. The ant...

The tail suspension test (TST) is a valid tool for assessing antidepressant activity. Association between depression and lower locomotion and exploration activities is also reported. In the present study, photoactometer, hole board and elevated plus maze tests were performed to evaluate locomotion, exploration and anxiety activities on animals of first and second set, however animals of second ...

Background: Depression was considered as mental illness worldwide. Various symptoms observed with depression are loss of interest, sad mood, disturbed sleep, low energy, and appetite. Mimosa pudica is a traditional medicine having various medicinal properties. Imipramine tricyclic antidepressant drug used in depression. This study to evaluate the activity ethanolic extract M. leaves imipramine ...

In past studies conducted by our group, riparin I (rip I) isolated from the green fruit of Aniba riparia presented antianxiety effects in mice, while its analogs rip II and III showed anxiolytic and antidepressant-like actions. This time around, we investigated a possible antidepressant activity of rip I using the forced swimming test (FST) and tail suspension test (TST) as predictive tests for...

Methods Dyn KO mice were generated by replacement of the entire coding region of the prodynorphin gene [2] and backcrossed onto C57bl/6N. Age and testing experiencematched female intact and ovariectomized (OVX) Dyn KO and wildtype (WT) mice at 3-8 months age were tested in all experiments. Anxiety (open field test, OF; elevated plus maze test, EPM; light dark test, LDT) and stressrelated behavi...

The tail suspension test (TST) is widely recognized as a useful experimental paradigm for assessing antidepressant activity and depression-like behavior. We have previously identified ubiquitin-specific peptidase 46 (Usp46) as a quantitative trait gene responsible for decreasing immobility time in the TST in mice. This Usp46 mutation has a 3-bp deletion coding for lysine in the open reading fra...

Objective: The present study was undertaken to evaluate the antidepressant and nootropic potential of aqueous extract of Indigofera tinctoria (ITAE). Methods: Antidepressant activity of ITAE was evaluated in mice by using the forced swim test (FST), tail suspension test tail suspension test and tetrabenazine induced catalepsy and ptosis models at doses of 250 and 500 mg/kg orally. Nootropic act...
