objective(s):there is much evidence indicating that depression is influenced by the levels of neurotransmitters such as dopamine, gaba and adrenaline. the current study we designed to investigate the effect of exposure of pregnant rats to different colors on neurotransmitters level, as indicators of mood disorders in off springs. materials and methods:five groups of pregnant female wistar rats ...

Amber, a plant resin, exhibits an anti-stress effect and is used in traditional medicine. Recently, it has been speculated that amber may possess anti-depressive effect. However, there no evidence to support this efficacy. Thus, study investigated the oxidative-stress-ameliorating effects of extract mice subjected restraint stress. Mice were treated with (25 50 mg/kg, p.o.) bupropion (10 as pos...

The nervous system processes sensory information and controls behavior by performing an enormous number of computations. These computations occur both within cells and between cells, but it is intercellular information processing, involving complex neural networks, that provides the nervous system with its remarkable functional capacity. The principal cells involved in information processing ar...

AIM To study the effect of Corynanthe Yohimbe (Yohimbe) on germ cells in Swiss albino mice. METHODS Adult male mice were orally (gavage) treated with different doses (188, 375 and 750 mg/[kg x day]) of aqueous suspension of Yohimbe for 90 days. The following parameters were evaluated: (i) reproductive organ weight, (ii) motility and count of sperm, (iii) study on rate of pregnancy and mean im...

this review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms. several studies have established that morp...

Objective(s): Hyperthermia is one of the most common environmental stressors that affect multi-biological systems in the body including the central nervous system as well as the hematopoietic organs. The objective of the present study was to investigate the protective role of ethanolic extract of propolis (EEP) on some selective stress markers, hematological, biochemical, and histopathological ...
