Depression is one of the most common psychiatric disorders that may result in significant consequences in active population of the society. In traditional manuscripts there are many indications about the antidepressant effects of rose oil, but so far no scientific research has been done about this subject. The purpose of present study was to determine the antidepressant effects of rose oil and ...

The cAMP-response element binding protein (CREB) is involved in antidepressant action, but the role of related CRE-binding transcription factors in the behavioral and endocrine responses to antidepressants is unclear. Alternative transcription of the cAMP response element-modulator (CREM) gene yields activator and repressor isoforms, including the strong repressor inducible cAMP early repressor...

Here we tested the hypothesis that stress-induced alterations in Neurogranin (Ng) synthesis and/ or utilization might underlie stress-related depression and anxiety. Rats were randomly divided into five conditions: chronic swim stress (CS), acute swim stress (AS), and three control groups. The CS group was exposed to daily swim stress (5 min/day) for 14 consecutive days, the AS group received a...

Immobility time of rats in the forced swim test was reduced after bilateral infusion of an 18-mer antisense phosphorothioate oligodeoxynucleotide targeted to the glucocorticoid receptor mRNA into the dentate gyrus of the hippocampus. Vehicle-, sense- and scrambled sequence-treated animals spent significantly more time immobile than antisense-treated animals during the initial test. Immunolabeli...

Here, we investigate the effects of electroacupunture on the depressive-like symptoms in learned helplessness and forced swim tests in rats. Electroacupuncture stimulation (EA) was provided at ST-36 (Zusanli) and SP-6 (Sanyinjiao) acupoints. A positive control group was treated with imipramine. To verify the effects of EA over serotonergic system, other additional groups received daily, for thr...

The functional role of brain G protein-coupled receptor 40 (GPR40) remains unclear. We investigated GPR40 signaling in depression-related behavior in mice via the forced swim test. A repeated but not a single intracerebroventricular administration of the GPR40 agonist, GW9508, reduced the duration of immobility behavior. Moreover, the levels of hippocampal non-esterified docosahexaenoic acid an...

In leukemia patients, stress and anxiety were suggested to predict poorer prognosis. Oncological patients experience ample physiological and psychological stress, potentially leading to increased secretion of stress factors, including epinephrine, corticosteroids, and prostaglandins. Here we tested whether environmental stress and these stress factors impact survival of leukemia-challenged rats...

Rodents exposed to a 15-min pretest swim in the forced swimming test (FST) exhibit prolonged immobility in a subsequent 5-min test swim, and antidepressant treatment before the test swim reduces immobility. At present, neuronal circuits recruited by antidepressant before the test swim remain unclear, and also less is known about whether antidepressants with different mechanisms of action could ...

BACKGROUND Stress is a normal part of everyday life but chronic stress can lead to a variety of stress-related illnesses including hypertension, anxiety, and depression. In the present investigation, standardized leaf extract of Epipremnumaureum was evaluated for its anti-stress potential. MATERIALS AND METHODS For the evaluation of anti-stress activity, groups of mice (n = 6) were subjected ...
