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...

CEREBRAL BLOOD FLOW Edited by M. Brock, C. Fieschi, D. H. Ingvar, N. A. Lassen, and K. Schurmann. (Pp. xx + 291; 113 figures; DM 58). Springer: Berlin. 1970. Measurement of the cerebral blood flow using isotope techniques is a field in which European centres have held the lead since their introduction by Lassen and Ingvar and by Harper exactly 10 years ago. Conferences at which the initiated ar...

V0 is the vascular distribution volume for the tracer in the tissue. In bolus type experiments such as H2O PET, this term is significant, whereas for inhalation of Xenon, the vascular term is not generally included, and Vo = 0. To measure CBF, the free parameters in Eq 1 are varied to obtain an optimal fit of the expression to regional uptake curves, using non-linear, least squared regression a...
