Background and Purpose The role of nitric oxide in cerebrovascular response to changes in
Pco2 is unclear. In the present study, we assessed responses at two levels of hypercapnia in …

Despite the increasing number of publications devoted to the cerebrovascular role of NO, its
precise influence in awake animals is still poorly characterized. The effect of nitric oxide …

Background and Purpose—Animal studies suggest that nitric oxide (NO) is important in
basal cerebral blood flow (CBF) regulation and that it may mediate the vasodilatory …

We studied the effect of nitro-L-arginine methyl ester (L-NAME), a nitric oxide synthase
(NOS) inhibitor, on the increases in cerebral blood flow (CBF) elicited by stepwise elevations …

The aim of the present study was to determine whether neuronal nitric oxide synthase
(nNOS)-derived nitric oxide (NO) plays a permissive role in the regulation of cerebral blood …

The role of nitric oxide (NO) synthesis in the cerebral hyperemic responses to hypercapnia
and hypoxia was investigated in anesthetized rats. Regional CBF (rCBF) measurements …

Background—From animal studies it emerged that nitric oxide is important for the
modulation of CO2-mediated cerebral blood flow (CBF chemoregulation) but not for the …

The importance of nitric oxide (NO) for CBF variations associated with arterial carbon
dioxide changes was investigated in halothane-anesthetized rats by using an inhibitor of …

The effect of the nitric oxide (NO) synthase inhibitor N ω-nitro-l-arginine methyl ester (l-
NAME) on the response of cerebrocortical oxygen consumption (CMRO2) and blood flow …

To test whether nitric oxide and prostaglandin pathways interact in hypercapnic cerebral
vasodilatation, cerebral blood flow (CBF) was measured in enflurane anaesthetized …
