the anxiolytic effect of the flower of echium. amoenum was shown in several experimental studies in mice. the present study was aimed to determine whether tolerance develops to anxiolytic action of e. amoenum in mice. nmri male mice were injected intraperitoneal with hydroalcoholic extract (12.5, 25 and 50 mg/kg) or saline once each day (8 am) for period of 7 days and then tested on light/dark ...

the present study was designed to study the preventive effect of hydroalcoholic extract of ripe pistachio hulls (rph) in the elevated plus maze model of anxiety. one hundred twenty female wistar rats in their estrous cycle were divided into 15 groups of 8 each and received various concentrations of hydroalcoholic extract of rph except the control groups. elevated plus maze was used to measure t...

Several lines of research on human and rodent subjects have demonstrated that early-life stress results in multiple negative outcomes, including increased incidence of psychopathologies. The current study sought to further the research on adolescent versus adult rats on anxiety-like reactions to chronic stress. The purpose of the current study was to assess whether 7 days of chronic restraint s...

The elevated plus-maze is a widely used model of anxiety in rodents and has recently been suggested as a putative model of anxiety or fear in swine. The aim of the present experiment was to examine the effects of a pretest blood sampling procedure on the behaviour of weaned pigs in an elevated plus-maze. Animals in the control group were lifted one-by-one into a transport trolley and moved to t...

The influence of ApoE gene deletion on the anxiety state has not been previously investigated. The elevated plus maze was used in this study to determine differences in anxiety-related behavior between apoE-deficient and wild type C57BL/6 mice. The apoE-deficient mice demonstrated less anxiety on the elevated plus maze by spending more time in the open arms of the elevated plus maze compared to...
