  • Abstract
  • Look Inside

The products resulting from arachidonic acid metabolism of the both cyclo-oxygenase and lipo-xygenase pathways possess strong physiological activities, such as vasoconstriction and the enhance-ment of vascular permiability. Therefore, it is likely that these metabolites are involved in cerebral cir-culatory disturbance and the formation of brain edema in cerebral ischemia. It is reported that intracerebral injection of leukotrien B4, C4, and E4 increased blood-brain barrier permeability. Thus, it is suggested that leukotrienes may induce vaso-genic cerebral edema.
