BACKGROUND In the present study, antidepressant-like activity of palmatine was evaluated in unstressed and stressed young male Swiss albino mice. METHODS The animals were subjected to unpredictable mild stress daily for 21 successive days to induce depression-like behavior. Palmatine (0.25, 0.5, 1 mg/kg, ip) was administered for 21 successive days to unstressed and stressed mice. The antidepr...

Alpha (α)-asarone is one of the main psychoactive compounds, present in Acorus species. Evidence suggests that the α-asarone possess an antidepressant-like activity in mice. However, the exact dose-dependent effect of α-asarone and mechanism(s) involved in the antidepressant-like activity are not clear. The present study aimed to investigate the dose-dependent effect of α-asarone and the underl...

Selective serotonin reuptake inhibitors, such as fluoxetine (FLX), are the most commonly used drugs in the treatment of major depression. However, there is a limited understanding of their molecular mechanism of action. Although the acute effect of selective serotonin reuptake inhibitors in elevating synaptic serotonin concentrations is well known, the clinical amelioration of depressive sympto...

Background: Recently, the role of electroacupuncture (EA) in chronic neuropathic pain has been widely reported. However, its specific mechanisms and ability to mitigate depression-like behaviors induced by remains unclear. This study aims determine analgesic antidepressant effect EA.

BACKGROUND:Post-partum depression is the most prevalent form of mental illness and herbal therapies are potential alternatives and adjuncts for its treatment. Hesperidin is the major flavonoid isolated from cit- rus fruits which has neuroprotective, antioxidant and antidepressant activity. OBJECTIVES: We studied the effect of exposure to Hesperidin during pregnancy on postpartum antide- pressan...

BACKGROUND It is a well-known fact that 5HT6 ligands increase glutamate levels. In the current study we investigated whether a 5HT6 antagonist, SB399885 would show antidepressant like property at a dose which would significantly increase the glutamate levels. Further we studied if the combination of a 5HT6 antagonist and N-methyl-D-aspartate (NMDA) antagonist, memantine would restore the antide...
