this activity of arachidonic acid was attributed in part to its bioconversion to pge2 , since its activity was significantly reduced by the prostaglandin antagonist , diphloretin phosphate ( dpp ) ( 60 mg/kg , i.v . ) and by indomethacin ( 20 mg/kg , i.p . ) , which blocks conversion of arachidonic acid to prostaglandins .
