title: Behavioral and neuronal biochemical possible effects in experimental induced chronic mild stress in male albino rats under the effect of oral barley administration in comparison to venlafaxine.
abstract: Venlafaxine is an antidepressant of choice, whose effectiveness could be modified by a commonly used medicinal plant and nutrient. The current study had evaluated the barley extract (1 g/kg) when compared to or combined to venlafaxine (32 mg/kg) in a rat stress model. The present study was conducted on 40 male Wister albino rats; divided to five groups. Four groups were subjected to social chronic mild stress. Drugs or saline were orally daily administered one week before stress induction and extended up to ten weeks. Behavioral, brain biochemical tests and serum magnesium were assessed at the end. The study revealed significant change in the combined group on behavioral tests; forced swim test, elevated plus maze and saccharin preference test when compared to barley extract group. Furthermore, there was significant reduction in brain malondialdehyde level, no significant change in brain nitric oxide level, while significant increase in serum magnesium level was noticed. Whereas, the barley extract group recorded a lowest significant improvement in behavioral, brain and serum biochemical tests. It could be concluded that barley and venlafaxine together had muffled the oxidant stress and increased brain serotonin, serum magnesium level that might had a crucial role in experimental induced chronic mild stress in rats.
