Green tea (C. sinensis) extract (GTE) dose dependently produced reversal of despair in normal, reserpinised and diabetic mice, thereby demonstrating an antidepressant effect. Although the exact mechanism is yet to be explored, the possible inhibition of catechol-o-methyl transferase and monoamine oxidase enzymes may be responsible for antidepressant activity of GTE.

The antidepressant action of cannabis as well as the interaction between antidepressants and the endocannabinoid system has been reported. This study was conducted to assess the antidepressant-like activity of Delta(9)-THC and other cannabinoids. Cannabinoids were initially evaluated in the mouse tetrad assay to determine doses that do not induce hypothermia or catalepsy. The automated mouse fo...

OBJECTIVE To perform a meta-analysis of antidepressant-antipsychotic cotreatment versus antidepressant or antipsychotic monotherapy for psychotic depression. DATA SOURCES We performed an electronic search (from inception of databases until February 28, 2011) in PubMed/MEDLINE, Cochrane Library, and PsycINFO, without language or time restrictions. Search terms were (psychosis OR psychotic OR h...

BACKGROUND Growth factors play an important role in regulating neurogenesis and synapse formation and may be involved in regulating the antidepressant response to conventional antidepressants. To date, Insulin-like growth factor I (IGFI) is the only growth factor that has shown antidepressant properties in human clinical trials. However, its mechanism of action remains unclear. METHODS The an...

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.

Cross hepatotoxicity between drugs in very uncommon. We report the case of a patient in whom acute hepatitis was induced by a tricyclic antidepressant, amineptine, and recurred early after administration of another tricyclic antidepressant, clomipramine. This observation suggests that the tricyclic ring is involved in the mechanism of the deleterious effect of both drugs to the liver.

Recent evidence shows that ghrelin plays an important role in depression. However, it was little known whether ghrelin produces antidepressant-like effect in the ovariectomized mice. The present study was aimed to investigate the antidepressant-like effects of the ghrelin in ovariectomized mice. In the forced swim test, ghrelin significantly decreased immobility time, reversing the "depressive-...

Although direct-to-consumer advertising (DTCA) has generated substantial controversy, little is known about its effects on consumer and physician behavior. In this article, the authors examine the impact of DTCA and physician detailing on the choice of antidepressant medication. The authors find that detailing has a much greater effect on medication choice in the antidepressant market than does...

DHIPC (2,4-dichloro-2´-hydroxyl-4´,6´-diisoprenyloxychalcone) is a new chalconecompound. In this study, its antidepressant-like activity of compound DHIPC was evaluated bythe forced swimming test and the tail suspension test in mice. The results showed that DHIPCsignificantly reduced the immobility time for 2 h after treatment through the oral administrationat dose of 10, 20, and 30 mg/kg in th...

BACKGROUND Agomelatine, the first melatonergic antidepressant, has been postulated to enhance the dopaminergic activity at the central nervous system by 5-hydroxytryptamine receptor type 2C (5-HT2C) antagonism, yet the impact of melatonergic agonism on this pathway is unclear. Previous studies employing simplified, yet reliable, proxy (retinal) measures of the central nervous system dopaminergi...
