Prostaglandins (Pgs) may protect against OFR-mediated cell injury by playing a cytoprotective role 2. Pg~s are generated through cyclooxygenase, COX-1 and COX-2. COX-1 is constitutively expressed, COX-2 is inducible. Expression and activity of cox is sensitive to oxidant stress. We examined the generation of Pgs in rat cardiomyocytes exposed to hydrogen peroxide (H20 z) and DX. DX generates the superoxide anion radical (OF-) causing its cardiotoxicity. Superoxide dismutase (SOD) and catalase (CAT) were used as free radical scavengers. An ex-vivo rat heart model was used
