Constrictor and dilator effects of angiotensin II on cerebral arterioles

In light of the equivocal data on the cerebral vasoconstrictor and vasodilator actions of angiotensin II (Ang II) and the potential clinical importance of this, we investigated the effects of Ang II on rat pial arterioles. We determined the effect of Ang I (3.10(-6) mol/L) in the absence and presenc...
