Prostaglandin Production by Macrophages and the Effect of Anti-inflammatory Drugs
Overview

1 Macrophages derived from peritoneal cavity inflammatory exudates of guinea-pigs produced substantial amounts of prostaglandin E2-like activity during in vitro culture, so providing the basis for an experimental model of prostaglandin production during inflammatory reactions. 2 Dose-related inhibition of prostaglandin biosynthesis was demonstrated by 16 acidic non-steroidal anti-inflammatory drugs. 3 Seven anti-inflammatory glucocorticosteroid preparations inhibited prostaglandin production in a dose-related manner. The relative potencies of dexamethasone, prednisolone and hydrocortisone were consistent with clinical anti-inflammatory ranking. Cortisone, however, failed to inhibit macrophage prostaglandin production. 4 Three other agents used in the treatment of inflammatory joint diseases were examined. Sodium aurothiomalate inhibited prostaglandin production, although higher concentrations were toxic to macrophages. D-Penicillamine did not affect macrophage prostaglandin production. Colchicine, in contrast, enhanced prostaglandin production at some concentrations. 5 The probable significance of macrophages as a source of prostaglandins, during inflammatory responses, is discussed.
