We microscopically and mechanically evaluated the femurs of rats subjected to hindlimb unloading (tail suspension) followed by treadmill training. Female Wistar rats were randomly divided into five groups containing 12-14 rats: control I (118 days old), control II (139 days old), suspended (tail suspension for 28 days), suspended-released (released for 21 days after 28 days of suspension), and ...

Asperugo procumbens L. has been used in Iranian traditional medicine for the refreshing, tranquillizing and mood elevating activities. The present study was undertaken to evaluate the antidepressant and sedative-hypnotic potential of acute administration of the hydroalcoholic extract of this plant in mice. Additionally, the effects of flumazenil on the hypnotic activity of the extracts were eva...

BACKGROUND Recently, experimental zinc deficiency has been correlated with depression-like alterations in rodents. METHODS In the first part of present study, the time course of zinc deficient diet induced alterations in the tail suspension test (TST) in mice was investigated. In the second part, the effect of imipramine and escitalopram in control and zinc-deprived for 3 weeks mice was exami...

Most classical preclinical tests to predict antidepressant activity were initially developed to detect compounds that influenced noradrenergic and/or serotonergic activity, in accordance with the monoaminergic hypothesis of depression. However, central opioid systems are also known to influence the pathophysiology of depression. While the tail suspension test (TST) is very sensitive to several ...

In the present study, we investigated plasma corticosterone levels of genetically modified mice lacking noradrenaline transporter (NET(-/-)), in response to the forced swim test (FST) and tail suspension test (TST). FST strongly increased the plasma corticosterone level in the first minute after the test (significantly only in NET(+/+) mice), while TST was without any significant effect in both...

Methods Three groups of rats were considered: SHAM, Bile Duct Ligation (BDL), BDL + hyperammonic dietary (BDLNH3). In each group, rats were treated by BNa or RFX. HE was assessed using neurocomportemental testing (6 minutes tail suspension test assessing the time of immobility). NH3 levels were assessed before sacrifice. BBB permeability was assessed by IV injection of a fluorochrome (Texas Red...

The influence of soy-protein diet on brain lipid peroxidation in female rats was studied using a tail-suspension model of weightlessness. The study tested the efficacy of diets containing 0% or 11.1% soy-protein in 4 groups of female Sprague Dawley rats that were maintained with or without tail-suspension for a period of 3 weeks. At term, the whole brain was removed, segmented, and analyzed for...

Objective(s) This study planned to assess antidepressant like activity of aqueous extract from leaves of Citrus maxima Merr. (Rutaceae). Materials and Methods Boiling was used for aqueous extraction. Acute toxicity study was performed in mice. Antidepressant activity was studied using locomotor activity test, modified forced swimming test (FST) and tail suspension test (TST). Three doses 100...

Astaxanthin (AX) is a carotenoid that exerts potent antioxidant activity and acts in the lipid bilayer. This study aimed to investigate effects of AX on muscle-atrophy-mediated disturbance mitochondria, which have Tail suspension was used establish muscle-atrophied mouse model. diet fed tail-suspension mice prevented loss muscle weight, inhibited decrease myofiber size, restrained increase hydr...
