title: Hydrocortisone and the release of prostaglandins from spleen.
abstract: An infusion of noradrenaline (1 mug/ml/min) released a PGE-like substance (PGEs) from superfused splenic strips of rabbits and from perfused cat spleen. The release of PGEs from rabbit splenic strips was not inhibited by the treatment of strips with hydrocortisone (40-150 mug/ml), but it was completely abolished in strips obtained from animals pretreated with hydrocortisone (1 mg/kg). The release of PGEs from the perfused cat spleen was reduced by hydrocortisone and abolished by indomethacin. It is concluded that the route of administration of hydrocortisone is essential for an appearance of its inhibitory effect on the PG release.
