Fabry disease is an X-linked inherited lysosomal storage disorder with intracellular accumulation of globotriaosylceramide (Gb3) due to α-galactosidase A (α-Gal A) deficiency. Fabry patients frequently report of anxiety, depression, and impaired cognitive function. We characterized affective and cognitive phenotype of male mice with α-Gal A deficiency (Fabry KO) and compared results with those ...

There is a strong association between depression and memory impairment. The present study aims to assess the nootropic activity of duloxetine and piracetam combination. Male Swiss Albino mice were divided randomly into 4 groups. Treatment of normal saline (10 ml/kg), duloxetine (10 mg/kg), piracetam (100 mg/kg), and duloxetine (5 mg/kg) plus piracetam (50 mg/kg) were given through intra-periton...

The anxiolytic-like activity of magnesium in mice during the elevated plus maze (EPM) has been demonstrated previously. In the present study, we examined the involvement of NMDA/glutamate receptor ligands on the magnesium effect on the EPM. We demonstrated that low, ineffective doses of NMDA antagonists (the competitive NMDA antagonist CGP 37849, 0.3 mg/kg; an antagonist of the glycineB sites, ...

Methamphetamines (MA) are psychostimulant drugs that are known to change individuals' behavior. Psychostimulants could either evoke positive emotions (e.g. joy and happiness) or attenuate negative emotional states (e.g. anxiety and depression) in humans. In animal experiments, the test of elevated plus-maze (EPM) is widely used. This test is appropriate f...

Systematic individual differences between male Wistar rats can be detected in paradigms such as the elevated plus maze (EPM), which is a widely used behavioral paradigm that measures fear-motivated avoidance behavior. It has been extensively used to assess anxiety profiles with face, construct and predictive validities. During a typical EPM test, animals actively avoid the open arms in favour o...

Our previous experiments have shown that adult male Wistar rats can differ systematically in elevated plus-maze (EPM) behaviour, which was related to the neurotransmitter serotonin in the ventral striatum. The EPM serves as a model of anxiety-like behaviour, and there is evidence that interleukin (IL)-2 in the brain may be related to anxiety-like behaviour, and that IL-2 interacts with the stri...

Objective: Cortexin is a polypeptide extract, used in clinics for its effects on memory, attention, and brain cortical processes. A synthetic analog of one Cortexin fraction, Cortagen (i.e. Ala-Glu-Asp-Pro peptide), was developed. Both agents stimulate neural growth in vitro, presumably in association with neurotrophic factors. We assessed the psychoactive effects of Cortexin and cortagen, usin...

Abstract We examined the activities of serotonin (5-HT) neurons in dorsal raphe nucleus (DRN) and corticotropin-releasing factor (CRF) hypothalamic paraventricular (PVN) during acute treadmill running at different speeds (control, low, high) durations (15, 30, 60 min) male Wistar rats using c-Fos/5-HT or CRF immunohistochemistry. also performed elevated plus maze test (EPM) forced swim (FST) af...

Herbal based remedies are used worldwide to treat psychiatric disorders. The aim of this study was to analyse the essential oil composition of Achillea Wilhemsii C. Koch (Asteraceae) and to evaluate its anxiolytic effects in the elevated plus maze (EPM) model of anxiety in rat. Gas chromatography/mass spectrometry (GC/MS) analysis of the essential oil showed that the main compounds of the oil w...

OBJECTIVE This research was aimed to evaluate the behaviors of short- or long-term antidepressant effects of ketamine in rats exposed to chronic unpredictable stress (CUS). BACKGROUND Ketamine, a glutamate noncompetitive NMDA receptor antagonist, regulates excitatory amino acid functions, such as anxiety disorders and major depression, and plays an important role in synaptic plasticity and le...
