total cyclo-oxygenase activity as measured by [ ( 14 ) c ] arachidonate metabolism to labelled prostaglandins by renal cortical and renal medullary microsomal fractions prepared from 6h-perfused kidneys demonstrated that renal-vein-constricted kidney-cortical cyclo-oxygenase activity was significantly greater than the contralateral-kidney-cortical conversion , whereas medullary arachidonate metabolism was comparable in both the renal-vein-constricted kidney and contralateral kidney .
