Cerebrovascular and metabolic effects of bradykinin, ATP and hypercapnia in the goat.

Abstract:

:Cerebral blood flow (CBF) and cerebral O2 metabolism (CMRO2) changes were measured in these studies during treatment with three reputed cerebral vasodilators: bradykinin, adenosine triphosphate (ATP) and increased arterial PCO2. Intracerebrovascular bradykinin infusions increased CMRO2 and CBF to a similar degree. Intramaxillary ATP infusions increased CBF to an extent greater than that required for increases seen in CMRO2. Hypercapnia increased CBF without a significant change in CMRO2. Results suggest that increases in cerebral metabolism may mediate most, some and none of the cerebrovascular changes produced by bradykinin, ATP or hypercapnia, respectively.

  • Sensitivity changes in guinea-pig atria and ileum following subacute administration of dyflos.

    abstract::1. Subacute administration of dyflos to guinea-pigs (1.2 mg/kg, s.c., daily for 10 days) led to the development of subsensitivity to carbachol in the ileum but not in the electrically stimulated left atrium. 2. Atria from dyflos-pretreated animals became supersensitive to acetylcholine but the ileum became subsensitiv...
