Numerous rodent models of depression have been reported, most requiring a long experimental period and significant effort. We explored a new potential mouse model for depression by investigating whether exposure to a 15-day chronic stress paradigm could induce depression-like behavior in ICR mice. Animals in the stress-exposed groups were subjected to 3 h of restraint while immersed in a 28°C...

UNLABELLED HISTORY AND OBJECTIVE: The aim of this study was to study the anxiolytic effects of Ocimum sanctum stress-induced anxiety. MATERIALS AND METHODS The study was carried out using male albino rats (200 ± 50 gm), male albino mice (25 ± 100) the effect of O. sanctum evaluated for anxiety and depression using forced swim test FST and rotarod test. RESULTS Restraint stress (3 hours/day ...

Perillae Herba (a leaf of Perilla frutescens) has been prescribed as one of the component herbs in certain Kampo (Japanese herbal) medicines that are used clinically for the improvement of depressive mood. l-Perillaldehyde (PAH) is a major component in the essential oil containing in Perillae Herba, but its antidepressant-like effect has not been reported. To clarify the antidepressant-like eff...

The orexin/hypocretin peptide signaling system plays a neuromodulatory role in motivation and stress; two critical components of depression. Although work has been done to identify links between orexin and depression, few specific neuroanatomical associations have been made. These studies have not investigated the relationship between orexin and orexin receptor expression in specific brain regi...

There is collecting evidence suggesting that the process of chromatin remodeling such as changes in histone acetylation contribute to the formation of stress-related memory. Recently, the ventrolateral orbital cortex (VLO), a major subdivision of orbitofrontal cortex (OFC), was shown to be involved in antidepressant-like actions through epigenetic mechanisms. Here, we further investigated the e...

This paper includes information required for establishing and conducting an occupational therapy program in an intensive care unit. Three common problems in the intensive care unit are immobility and prolonged bed rest, sensory deprivation and stress, and prolonged mechanical ventilation. The resolution of these rehabilitation problems through occupational therapy intervention is addressed.

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...

Objective: Rosa damascena mill L (R. damascena) is a medicinal plant mostly known in the world for its perfume. It also has beneficial effects on stress, tension and depression. In this experiment antidepressant effect of ethanolic extract of R. damascena by forced swimming test (FST) was evaluated. Material and Methods: Animals received ethanolic extract (15, 60 and 90 mg/kg, i.p), imipramine...
