salvia verticillata is one of the salvia species which possesses remarkable antioxidant activity. in the present study, we investigated the possible effects of hydro-alcoholic extract from salvia verticillata plant (sve) in various models of anxiety, depression and seizure in mice. mice were randomly divided into control (saline), sve-treated and standard treatment groups. the sve-treated group...

The forced swim test in rodents has been widely used to evaluate potential effectiveness of antidepressant medications since it was described in 1977 by Porsolt. In this test, a rodent is placed in a water container, and its immobility time is measured. The immobility time indicates the level of inactivity, interpreted as ‘hopelessness’, and has been shown to decrease when the rodent is treated...

The present study examined the effect of citalopram (7.5 and 15 mg/kg) in the modified forced swim test (FST) in Wistar rats, in comparison to the effect of desipramine at the same doses. The citalopram at both doses increased swimming behavior, at the cost of climbing and immobility. The administration of desipramine increased climbing behavior while immobility counts were decreased. The modif...

We showed previously that cAMP response element-binding protein (CREB) within the nucleus accumbens (NAc) of rats regulates immobility in the forced swim test (FST), an assay used to study depression. Because CREB regulates expression of dynorphin (which acts at -opioid receptors) in NAc neurons, these findings raised the possibility that -receptors mediate immobility behaviors in the FST. Here...

In order to evaluate the effect of olive juice on the anxiety and depression behavior, the paper uses olive juice concentrate as experimental material, and uses mice as experimental subjects. Mice are randomly divided into negative, positive, high, medium and low-dose group, administered orally for 7 days. And observe the impact on the mice elevated plus maze test, the opening acts test and for...

The forced swim test (FST) is a pre-clinical test to short and long term treatment with antidepressant drugs (ADT), which requires between-subject designs. Herein a modified protocol of the FST using within-subject design (repeated rat-FST) was evaluated. Male Wistar rats were submitted to 15 min of swimming (Day 1: pretest) followed by three subsequent 5 min-swimming tests one week apart (Day ...

In the present study, we investigated plasma corticosterone levels of genetically modified mice lacking noradrenaline transporter (NET(-/-)), in response to the forced swim test (FST) and tail suspension test (TST). FST strongly increased the plasma corticosterone level in the first minute after the test (significantly only in NET(+/+) mice), while TST was without any significant effect in both...

BACKGROUND Sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, has recently been reported to influence the antidepressant activity of some antidepressant drugs. The present study was undertaken to investigate the involvement of the nitric oxide/cyclic guanosine 3',5'-monophosphate/PDE5 (NO/cGMP/PDE5) signaling pathway in the antidepressant activity of paroxetine and to assess the inte...

The forced swim test (FST) is a preclinical test to the screening of antidepressants based on rats or mice behaviours, which is also sensitive to stimulants of motor activity. This work standardised and validated a method to register the active and passive behaviours of Swiss mice during the FST in order to strength the specificity of the test. Adult male Swiss mice were subjected to the FST fo...

We showed previously that cAMP response element-binding protein (CREB) within the nucleus accumbens (NAc) of rats regulates immobility in the forced swim test (FST), an assay used to study depression. Because CREB regulates expression of dynorphin (which acts at kappa-opioid receptors) in NAc neurons, these findings raised the possibility that kappa-receptors mediate immobility behaviors in the...
