The methanolic leaf extract of Thuja occidentalis was evaluated for possible sedative activities in mice. Sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (EPM) tests at 200mg/kg and 400 mg/kg.  The extract decreased the locomotor activity of mice in hole cross, open field and EPM test and showed the remarka...

OBJECTIVE To investigate whether lithium modifies open-field and elevated plus maze behavior, and brain phospho-glycogen synthase kinase 3 (P-GSK3beta) expression in Fmr1 knockout mice. METHODS One hundred and eighty FVB mice, including knockout and wild type, with an age of 30 days were used. An open-field and elevated plus maze was utilized to test behavior, while western blot was used to m...

The influence of the blockade of group I metabotropic glutamate receptors (I mGluRs) by AIDA on some behavioral effects of rats pretreated with baclofen, an agonist of GABA-B receptor, was investigated using behavioral tests: the open field, the passive avoidance response and the elevated "plus" maze. Baclofen, applied intraperitoneally (ip) at a dose of 0.25 mg/kg, increased the number of cros...

The influence of the blockade of group I metabotropic glutamate receptors (mGluRs) by AIDA [(RS)-1-aminoindan-1,5-dicarboxylic acid] on some behavioral effects was tested in control groups of rats and in rats that underwent short-term hypoxia. We used the following methods: the open field test, the passive avoidance test and the elevated "plus" maze test. In rats without hypoxia, AIDA (100 nmol...

Based on the extensive application of Peganum harmala (P.h) seeds in the Asian traditional medicine, we tried to investigate its possible anxiety effect. Method: The effect of P.h. extract inhalation was evaluated in adult male rats using elevated plus-maze apparatus. The humidity of prepared ethanol extract was 37%. Animals in different groups (n=6) received 2, 4, 6, 12 or 18 gr/ml doses of...

Undecided voters represent a major challenge to political pollsters. Recently, political psychologists have proposed the use of implicit association tests (IAT) to measure implicit attitudes toward political parties and candidates and predict voting behavior of undecided voters. A number of studies have shown that both implicit and explicit (i.e., self-reported) attitudes contribute to the pred...

α-galycoceramide (α-galcer) or the common name of krn7000 is an α-gelasphin derivative. the α-galcer structure consists of a galactose combined with a ceramide in an α-configuration. social isolation (si) has been linked with enhanced inflammation, through modifications in transcriptional pathways linked with glucocorticoid, to stress. our hypothesis is to investigate mediatory role of glucocor...

The present work is to evaluate the anxiolytic activity of a hydroalcoholic extract of Tephrosia purpuria (L) Pers (HAETP) in mice using the elevated plus-maze (EPM), elevated zero-maze (EZM), Y-maze and hole-board models. Furthermore, the anxiolytic effects of HAETP were compared to a known active anxiolytic drug diazepam. The extract, administered orally, in two different doses of HAETP 200 m...
