Depression is a multifactorial illness and genetic factors play a role in its etiology. The understanding of its physiopathology relies on the availability of experimental models potentially mimicking the disease. Here we describe a model built up by selective breeding of mice with strikingly different responses in the tail suspension test, a stress paradigm aimed at screening potential antidep...
OBJECTIVE Pediatric depression is associated with significant functional impairment at school and at work. Recently, we reported on depression-like behavior in juvenile mice neonatally exposed to dexamethasone (DEX) as a potential animal model for pediatric depression. The N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has promoted rapid and long-lasting antidepressant effects in pati...
Background Hydrogen sulfide (H2S) is a crucial signaling molecule with a wide range of physiological functions. Previously, we confirmed that stress-induced depression is accompanied with disturbance of H2S generation in hippocampus. The present work attempted to investigate the inhibitory effect of H2S on chronic unpredictable mild stress-induced depressive-like behaviors and the underlying me...
BACKGROUND Neuropsychiatric signs are critical in primary caregiving of Alzheimer patients and have not yet been fully investigated in murine models. METHODS 18-month-old 3×Tg-AD male mice and their wild-type male littermates (non-Tg) were used. The open field test and the elevated plus maze test were used to evaluate anxiety-like behaviors, whereas the Porsolt forced swim test, the tail susp...
The neurogenesis hypothesis of major depression has two main facets. One states that the illness results from decreased neurogenesis while the other claims that the very functioning of antidepressants depends on increased neurogenesis. In order to verify the latter, we have used cyclin D2 knockout mice (cD2 KO mice), known to have virtually no adult brain neurogenesis, and we demonstrate that t...
Background: This study used inhalation toxicity experiments, open field and tail suspension tests to investigate the antidepressant effect of a combination nine types refined oils extracted from domestic native plants.Methods: Non-irritability was confirmed through an test, locomotor activity measured using assessed by measuring immobility time during test.Results: The test that both samples we...
Salvia verticillata is one of the salvia species which possesses remarkable antioxidant activity. In the present study, we investigated the possible effects of hydro-alcoholic extract from Salvia verticillata plant (SVE) in various models of anxiety, depression and seizure in mice. Mice were randomly divided into control (saline), SVE-treated and standard treatment groups. The SVE-treated group...
Objective(s): Our previous studies have shown that MgO nanoparticles (MgO NPs) could improve anxiety and reduce pain in animals. In this study, the effect of co administration MgO NPs and vitamin C on anxiety like behavior and nociception in postpartum depression (PPD) model were investigated.Materials and Methods: Female mice (27 ± 3 g) were divided into groups: two control groups, PPD groups...
The prevalence of depression increases with aging. We hypothesized that like humans, old animals exhibit anhedonic-like behavior, along with signs of behavioral despair. In rodents, anhedonia, a reduced sensitivity to reward, which is listed as a core feature of major depression in the DSM-IVR, can be measured by a decrease in intake of and preference for sweet solutions. Here, sucrose intake, ...
Dysfunction of central serotonin (5-HT) system has been proposed to be one of the underlying mechanisms for anxiety and depression, and the association of diabetes mellitus and psychiatric disorders has been noticed by the high prevalence of anxiety/depression in patients with diabetes mellitus. This promoted us to examine these behaviors in central 5-HT-deficient mice and those also suffering ...
