Transient cerebral ischemia and brain prostaglandins

Abstract
Prostaglandin levels were measured in gerbil brain during cerebral ischemia for up to 2 hours, and during reperfusion after various periods of transient ischemia. The levels of PGF and its metabolite (13,14-dihydro-15-keto-PGF) were low and did not change during ischemia. However, PGF, 13,14-dihydro-15-keto-PGF, PGE2, and thromboxane B2 increased during reperfusion after brief episodes of ischemia. Indomethacin or aspirin inhibited this increase. Animals pretreated with indomethacin recovered more rapidly and were more active during reperfusion than those without treatment.
