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...

Our previous studies demonstrated that joint administration of a tricyclic antidepressant drug, imipramine (IMI) with the uncompetitive antagonist of NMDA receptor, amantadine (AMA), produced stronger "antidepressant" effect in the forced swimming test (Porsolt's test) than the treatment with either of drugs given alone. Since it has been suggested that, in addition to their other functions, do...

The present study has been designed to find out the effects of forced swimming-induced oxidative stress imposition on primary and secondary sex organs and its protection by plant extract in male Wistar strain rats. This work has been designed to find out the scientific basis of the local use of the composite extract of root of Withania somnifera, leaf of Ocimum sanctum and rhizome of Zingiber o...

Background: Strenuous exercise and temperature outside the optimum are associated with hypothalamic dysfunction and therefore disruption of fertility in females. The aim of this study was to evaluate serum Estradiol level and follicogenesis in adult mice exposed to forced swimming in different temperature waters. Materials and Methods: Adult female mice were randomly divided into four groups as...

The effects of a silk amino acid (SAA) preparation on the physical stamina and male reproductive function of mice were investigated. Eight-week-old male ICR mice (29-31 g) were orally administered SAA (50, 160 or 500 mg/kg) for 44 d during 30-min daily swimming exercise. The mice were subjected to a weight-loaded (5% of body weight) forced swimming on the 14th, 28th and 42nd day to determine ma...

This study reports the first results on telemetry of caudal differential pressure during spontaneous swimming activity in cod Gadus morhua and demonstrates that tail-beat pressure may be used as a predictor of activity and swimming costs of free-swimming cod. Tail-beat pressure was monitored using a differential pressure sensor on the caudal peduncle of cod and spontaneous swimming activity was...

We investigated whether acute stressors regulate functional properties of the hippocampal mineralocorticoid receptor (MR), which acts inhibitory on hypothalamic-pituitary-adrenocortical activity. Exposure of rats to forced swimming or novelty evoked a significant rise in density of MR immunoreactivity in all hippocampal subfields after 24 hr, whereas exposure to a cold environment was ineffecti...

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...
