Cedrus deodara (Pinaceae) has been used traditionally in Ayurveda for the treatment of central nervous system disorders. 3,4-bis(3,4-dimethoxyphenyl)furan-2,5-dione (BDFD) was isolated from heart wood of Cedrus deodara and was shown to have antiepileptic and anxiolytic activity. Thus, the present study was aimed to explore its anti-depressant effect and to correlate the effect with serotonin an...

Objective(s): Curcumin, a plant alkaloid from Curcuma longa, possess antioxidant and anti-inflammatory properties. Recently, the antidepressant activities of curcumin were reported. Nevertheless, bioavailability of curcumin limits its therapeutic utility. Nanotechnology is a developing field that potentially enhances bioavailability and the plasma concentration of curcumin. This study investiga...

Most classical preclinical tests to predict antidepressant activity were initially developed to detect compounds that influenced noradrenergic and/or serotonergic activity, in accordance with the monoaminergic hypothesis of depression. However, central opioid systems are also known to influence the pathophysiology of depression. While the tail suspension test (TST) is very sensitive to several ...

Sickness behavior appears to be the expression of a central motivational state that reorganizes the organism's priorities to cope with infectious pathogens. To evaluate the effect of dipyrone in lipopolysaccharide (LPS)-induced sickness behavior, mice were subjected to the forced swim test (FST), tail suspension test (TST), dark-light box test, open field test, sucrose preference intake test an...

Objective: The goal of the present study was to assess antidepressant-like action Withania qaraitica in two behavioral animal models, forced-swimming test (FST) and tail suspension (TST) mice. Methods: methanolic extract prepared by maceration. antidepressant activity measured using C57BL/6 mice BALB/c Mice were divided into three groups: control (DMSO), standard (citalopram desipramine), (n = ...

CONTEXT Depression, a sustained mood disorder caused by selective diminution of specialized cells in brain is increasing at an alarming rate. It will be the second largest morbid illness by next decade and is the leading cause of suicidal deaths. The available antidepressant medications benefit only a third of its recipients and have many side effects. Hence, it is imperative to search in Ayurv...

The present study was undertaken to investigate the effect of aqueous and ethanolic extracts of T. bellirica on depression in mice using forced swim test (FST) and tail suspension test (TST). The extracts were administered orally for 10 successive days in separate groups of Swiss young male albino mice. Aqueous extract (50, 100 and 200 mg/kg) in a dose-dependent manner and ethanolic extract (10...

The role of the opioid system in mediating effects of alcoholism and stress in depression is far from clear. We studied, therefore, the effects of chronic mild stress (CMS) and alcohol drinking on depression-like behavior and nociception in lines of mice selected for high (HA) or low (LA) swim stress-induced analgesia. Compared to the LA mice, the HA animals display up-regulation of opioid rece...

Depression, a bewildering and burdensome illness, is one of the commonest psychiatric diseases. It is expected to be the second leading contributor to Global Disease Burden by 2020. The objective of the study was to determine the effect of nifedipine on the responses of imipramine, sertraline and furosemide in the forced swim test (FST) and tail suspension test (TST) in mice. Groups of mice wer...
