Effects of DS on blood pressure and resting CBF. Mean arterial blood pressure (MABP) was measured from the femoral artery (a) and cerebral blood flow (CBF) was measured within middle cerebral artery branches (b) during intravenous infusion of DS. Values are expressed as a percent change from baseline immediately before infusion. DS slightly increased resting CBF in a concentration-dependent manner in the cortex (P > .05 versus baseline), although it caused mild hypotension. Values are expressed as means ± SEM of five separate experiments. *P < .05 versus control.
