OBJECTIVES The aim of present study was to evaluate some effects of Crinum zeylanicum (C. zeylanicum) on central nervous system. MATERIALS AND METHODS C. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using Irwin test, pentobarbitone-induced sleep test, spontaneous motor activ...

Stroke is an ischemic disease caused by clotted vessel-induced cell damage. It is characterized by high morbidity and mortality and is typically treated with a tissue plasminogen activator (tPA). However, this therapy is limited by temporal constraints. Recently, several studies have focused on cell therapy as an alternative treatment. Most researches have used fixed donor cell administration, ...

Mouse models of Alzheimer’s disease (AD) show both cognitive and neuromotor impairments. We measured motor ability and motor learning of male and female triple transgenic (3×Tg-AD) and control (B6129SF1/J) mice on the accelerating Rotarod in a cross-sectional design at 2, 6, 9, 12, and 15 months of age. At all ages except for 2 months, transgenic mice performed better and had a steeper motor le...

Lurcher mutant mice represent a model of olivocerebellar degeneration. They suffer from cerebellar ataxia and deterioration of cognitive functions. The aim of the work was to study the effect of repetitive enforced motor training on spatial learning ability and motor coordination in adult Lurcher mutant mice of the C57BI strain. Experimental mice were trained repetitively on a rotarod. Control ...

Objective(s): The present study aims at examining the motor coordination performance, serum and cerebellar estrogen, as well as ERβ levels, of ovariectomized rats (as menopausal model) following regular exercise. Materials and Methods:Ten female Sprague Dawley ratsaged 12 weeks old were randomly divided into two groups; all of which underwent ovariectomy. The first group was treated with regula...

Oxidative stress and reactive oxygen species (ROS) such as hydrogen peroxide (H2O2), which is detoxified by catalase, are implicated in fetal death and birth defects, but embryonic levels of catalase are only about 5% of adult activity, and its protective role is unknown. Our approach involved the use of mice genetically modified to either: (1) express low levels of endogenous catalase (acatala...

BACKGROUND AND PURPOSE Enhanced angiogenesis facilitates neurovascular remodeling processes and promotes brain functional recovery after stroke. Previous studies from our laboratory demonstrated that valproate (VPA), a histone deacetylase inhibitor, protects against experimental brain ischemia. The present study investigated whether VPA could enhance angiogenesis and promote long-term functiona...

Linalool oxide is a monoterpene that is found in some species of aromatic plants. The effects of the inhalation of linalool oxide (0.65%, 1.25%, 2.5% and 5.0% w/w) in the elevated plus-maze and light/dark box tests as animal models of anxiety were investigated in adult male mice and compared with the effects of the reference anxiolytic diazepam (0.5 and 2.0 mg/kg), administered intraperitoneall...
