introduction: effective perception of fear signals is crucial for organism survival. when threated, the organism indicates defensive behaviors. methods: elevated plus–maze has high efficiency for measurement of fear behavior and is widly used for fear behavior determination. increase in two parameters percent of openarm entries (%oae) and percent of time spent in the open-arm (%oat) in the elev...

Benzodiazepines (BZDs) are widely used in clinical practice as anxiolytics, hypnotics, anticonvulsants, and muscle relaxants. However, they have some undesired effects including memory problems. In continuing our research on novel benzodiazepine ligands, we are looking for ligands with less adverse effects. Previously, 4 novel derivatives of 2-phenoxy phenyl-1,3,4-oxadiazole were synthesized as...

Portulaca oleracea (PO) overgrows in the different parts of Iran. In previous studies, ethanolic extracts of PO showed antinociceptive activity, sedative in animal. This study was designed to evaluate anxiolytic effects in different doses of the aqueous decoction extracts of PO. In this study, fourty male mice (25-30 g) were used in elevated plus maze model. Different doses of the extract. (25,...

There is growing interest in flavonoids for their wide array of biological actions. In neurodegenerative disorders these naturally occurring polyphenolic compounds, are known to inhibit proinflammatory mediators such as in TNF–? and IL-6 in lipopolysaccharide (LPS) stimulated neuronal degeneration, which are associated with Alzheimer’s and Parkinson’s disease. Recent studies on flavonoids have ...

In recently, many studies tried that fine medicinal plant that may be useful in treatment of psychological diseases. Coriandrum sativum (CS) overgrows in the different parts of Iran. In this study we investigated the effects of hydro-alcoholic extract of Coriandrum sativum on anxiety reaction in Mice. In this study, fourty male mice (25-30 gr) in elevated plus maze model were used. Different do...

Background & Aims: Iron is an essential element for correct brain function. Iron deficiency changes some behaviors such as anxiety and nociception. Recently, nano-iron, Ferric or ferro oxide (nano-Fe2O3 or Fe3O4), are used in various applications in agriculture, industry and medicine, but their effects on the heath and behavior is not clear. In this study, the effects of Fe2O3 nanoparticles on ...

The endocannabinoid system is involved in the control of many physiological functions, including the control of emotional states. In rodents, previous exposure to an open field increases the anxiety-like behavior in the elevated plus-maze. Anxiolytic-like effects of pharmacological compounds that increase endocannabinoid levels have been well documented. However, these effects are more evident ...

Previous studies indicated that Foeniculum vulgare (FV) as a folk remedy plant that overgrows in the different parts of Iran and suggested that have antinociceptive activity and sedative. In this study, we investigated of anxiolytic effects in different doses of the extracts of FV. In this study, fourty male mice (25-30 gr) were used in elevated plus maze model. Different doses of the extract o...
