objective(s) this study planned to assess antidepressant like activity of aqueous extract from leaves of citrus maxima merr. (rutaceae). materials and methods boiling was used for aqueous extraction. acute toxicity study was performed in mice. antidepressant activity was studied using locomotor activity test, modified forced swimming test (fst) and tail suspension test (tst). three doses 100, 2...

The mating system of eastern mosquito fish (Gambusia holbrooki) is dominated by male sexual coercion, where all matings are forced and females never appear to cooperate and actively avoid all attempts. Previous research has shown that male G. holbrooki offer a model system for examining the benefits of reversible thermal acclimation for reproductive success, but examining the benefits to female...

objective: rosa damascena mill l (r. damascena) is an ornamental plant that has several therapeutic (such as sedative and hypnotic) effects. it also heals depression, grief, nervous stress and tension. in the present study we evaluated antidepressant-like effect of r. damascena using forced swimming test (fst). material and methods: three doses of aqueous extract (15, 60 and 90 mg/kg) was injec...

Effects of REM sleep (REMs) deprivation on the basal swimming activity and the tricyclic anti-depressants-induced increase in swimming activity in the forced swimming test were investigated. Immediately after a 48-hr period of REMs deprivation, the basal swimming activity in REMs-deprived mice was significantly higher than those in group-housed and socially isolated animals used as the control ...

objective: the present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of crocus sativus l. (saffron) using mice in two different regimens of acute and sub-acute administration. material and methods: in acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

asperugo procumbents l. has been used in iranian traditional medicine for the refreshing, tranquillizing and mood elevating activities. the present study was undertaken to evaluate the antidepressant and sedative-hypnotic potential of acute administration of the hydroalcoholic extract of this plant in mice.additionally, the effects of flumazenil on the hypnotic activity of the extracts were eva...

withania somnifera (ws) possess anti-inflammatory and antioxidant properties. ws preparations have a potential therapeutic role in the central nervous system (cns) related disorders in animal models. in this study, the possible protective effect of acute aqueous ws root extract on behavioral despair was explored and compared with fluoxetine, an antidepressant with selective serotonin (5-ht) reu...

Background: Sports, hypothermia and hyperthermia as some stressors inhibit male reproductive functions and are associated with subfertility or infertility. We investigated whether water temperature and chronic swimming are effective on mouse sperm parameters. Materials and Methods: Adult male mouse(N=35) were randomly divided into 7 groups: 1-controls 2-cold water (100C) with swimming 3- cold w...

A fundamental issue in locomotion is to understand how muscle forcing produces apparently complex deformation kinematics leading to movement of animals like undulatory swimmers. The question of whether complicated muscle forcing is required to create the observed deformation kinematics is central to the understanding of how animals control movement. In this work, a forced damped oscillation fra...
