Effect of noradrenalin on endogenous prostaglandin E and F2α production in cerebral and extracranial vessels of cats

  • É. A. Amroyan
  • É. S. Gabrielyan


The production of prostaglandins (PG) E and F in the isolated cerebral and extracranial vessels of cats was determined quantitatively. Basal PG production was found to be greater in the cerebral vessels, and PGF exceeded PGE. On incubation of isolated vessels with noradrenalin, production of vasopressor PGF was reduced, and this was accompanied by a considerable increase in the content of vasopressor PGE. The difference was particularly marked in the cerebral vessels. The level of endogenous PG production by the cerebral vessels, it can tentatively be suggested, has an important role for the local regulation of vascular tone, and a disturbance of their dynamic ratio may be one cause of the development of cerebrovascular pathology.
