Introduction: Ischemic preconditioning (IPC) is an endogenous phenomenon that can induce ischemic tolerance (IT) in variety of organs such as brain. In this study, we examined the intermittent and prolonged dose of normobaric hyperoxia (HO) on neurologic deficit scores, infarct volume, and catalase activity. Material and Method: The rats were divided to four main groups. First two main groups w...

Background: German chamomile (Matricaria recotita) as a medicinal plant has several therapeutic effects. Since the extract of this plant contains a high amount of α-bisabolol (Terpenoid) its antibacterial properties can be considered. Staphylococcus aureus as a pathogenic bacterium is important in clinical situations and food hygiene. So, investigation of effects of antibacterial compounds agai...
