comparing cerebral blood flow auto regulation in
introduction : cerebral autoregulation (ca) and mean cerebral blood flow velocity in males and females are still under controversy. the present study was scheduled to address the effect of sex on these parameters. materials and methods : the present study was interventional and performed on 30 healthy volunteers (15 males aging from 20-30 yrs and mean age of 23.9±3 years old and 15 females agin...
متن کاملCerebral Blood Flow Regulation
Rapid vascular resistance adjustments in the brain and in the circle of Willis have been continuously measured and enhanced by signal averaging methods. Naftidrofuryl, a drug chemically similar to local anesthetics and to beta adrenergic blocking agents, increases local CBF by reducing resistance in brain and in extracerebral supply arteries. It has also been reported to affect brain metabolism...
متن کاملTitle : Cerebral blood flow during exercise ; mechanisms of regulation 1
21 The response of cerebral vasculature to exercise is different from other peripheral 22 vasculature; it has a small vascular bed, and is strongly regulated by cerebral 23 autoregulation and the partial pressure of arterial carbon dioxide (PaCO2). In contrast to 24 other organs, the traditional thinking is that total cerebral blood flow (CBF) remains 25 relatively constant and is largely unaff...

متن کاملRegulation of Cerebral Blood Flow
The control of cerebral blood flow is complex, and only beginning to be elucidated. Studies have identified three key regulatory paradigms. The first is cerebral pressure autoregulation, which maintains a constant flow in the face of changing cerebral perfusion pressure. Flow-metabolism coupling refers to the brains ability to vary blood flow to match metabolic activity. An extensive arborizati...
