The antidepressant-like, antianxiety-like and sedative effects of tryptophan (TRP), in the absence and presence of p-chlorophenylalanine (p-CPA), and melatonin were studied in mice using the forced-swimming test, open-field test and activity cage, respectively. Single-dose TRP caused an
Recent studies suggest the possible involvement of serotonergic and endocannabinoid systems in analgesic, anxiolytic, and anticonvulsant-like actions of paracetamol. Considering the fact that these systems play intricate roles in affective disorders, we investigated the effects of paracetamol in
Little is known about the action of neuropeptide AF (NPAF) on anxiety and depression. Only our previous study provides evidence that NPAF induces anxiety-like behavior in rats. Therefore, the aim of the present study was to investigate the action of NPAF on depression-like behavior and the
Diabetes is associated with anxiety and depression. Resveratrol, one of the most potent natural polyphenols with antioxidant properties, has been demonstrated to have benefits against diabetes. In the current study, we investigated the effects of resveratrol on depression and Anxiety and depression are pathologies that affect human beings in many aspects of life, including social life, productivity and health. Cannabidiol (CBD) is a constituent non-psychotomimetic of Cannabis sativa with great psychiatric potential, including uses as an antidepressant-like and
In this study, we investigated whether glucagon-like peptide-2 (GLP-2) had antidepressant-like effects in mice, and whether these activities were associated with monoamine systems in mice. Antidepressant-like effects were evaluated based on the immobility time in the forced-swim test. GLP-2 (1.5-6
We investigated the effectiveness of glucagon-like peptide-2 (GLP-2) against refractory depression in adrenocorticotropic hormone (ACTH)-treated mice as a model of tricyclic antidepressant (TCA)-resistant depression. Chronic ACTH treatment (0.45 mg/kg, s.c., 14 days) weakened the antidepressant-like
This study investigated the possible antidepressant-like and anxiolytic-like effects of diphenyl diselenide, (PhSe)(2) in mice. The involvement of L-arginine-nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway in the antidepressant-like effect was also evaluated. The immobility times in
Depression is a common and debilitating mental illness and is often comorbid with anxiety disorders. Altered synaptic plasticity is considered to be an important mechanism underlying antidepressant drug action. It has been reported that hydrogen sulfide (H2S), the third gaseous transmitter,
Serotonergic agents have been widely used for treatment of psychiatric disorders, but the therapeutic effects are insufficient and these drugs often induce severe side effects. We need to specify the distinct serotonergic pathways underlying each mental function to overcome these problems.
The effects of microinjection of the nitric oxide (NO) precursor l-arginine (l-Arg), the NO synthase (NOS) inhibitors N-methyl-l-arginine (l-NAME) and 7-nitroindazole (7-NI), and the cyclic guanosine 3',5'-monophosphate (cGMP) analog 8-Br-cGMP into the dorsal raphe nucleus (DRN) were assessed in
Growth factors in the brain are important to depression and it's treatment and we assessed the ability of peripherally administered insulin-like growth factor-I (IGF-I) to influence behavior related to depression. We found that mice that received chronic IGF-I treatment showed antidepressant-like
We previously reported that tipepidine, a centrally acting non-narcotic antitussive, has an antidepressant-like effect in normal and imipramine treatment-resistant depression model rats. Recently, mapping the induction of c-fos-like immunoreactivity (FLI) in the rat brain showed FLI-positive neurons
Previous studies have demonstrated that repeated submission of rats to mild hypobaric hypoxia reduces the persistent behavioral and hormonal depressive symptoms induced by exposure to footshock in the learned helplessness paradigm. The aim of this study was to determine whether hypoxic
