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...

objective: the present study was undertaken to evaluate anti-depressant activity of myristica fragrans(ms). materials and methods: male wistar rats were subjected to imipramine and herbal extract ofms for their antidepressant activity using forced swimming test (fst), reserpine reversal test (rrt), haloperidol-induced catalepsy (hic), and pentobarbitone sleeping time (pst). results: administrat...

objective: pimpinella anisum (p. anisum) has different pharmacological properties such as anticonvulsant, analgesic, tranquilizer, antidepressant and anti-anxiety effects. in this study the antidepressant-like effect of aqueous and ethanolic extracts of p. anisum fruit in mice was investigated. materials and methods: forced swimming test (fst) and tail suspension test (tst) were used to determi...

BACKGROUND The aim of present study was to evaluate antidepressant-like activity of ellagic acid in Swiss young male albino mice; and to explore the possible underlying mechanisms for this activity. METHODS Mice were immobilized for 150 min once only for induction of stress. Ellagic acid (8.75, 17.5, 35 mg/kg, po) and fluoxetine (20 mg/kg, ip) per se were administered to unstressed and stress...

This study investigated the antidepressant activity of ethanolic extract of U. lanosa Wallich var. appendiculata Ridsd (UL(EtOH)) for two-weeks administrations by using FST and TST on mice. In order to understand the probable mechanism of antidepressant-like activity of UL(EtOH) in FST and TST, the researchers measured the levels of monoamines and monoamine oxidase activities in mice brain, and...

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...

Several lines of evidence suggest an antidepressant-like activity for 3-[(methyl-1,3-thiazol-4-yl)ethynyl]-pyridine (MTEP), a highly selective, non-competitive antagonist of metabotropic glutamate receptors subtype 5 (mGluR(5)). This effect has been observed following both acute and chronic MTEP treatments in behavioral tests and experimental models of depression, such as the forced swim test (...
