HYDROCORTISONE‐INDUCED INHIBITOR OF PROSTAGLANDIN BIOSYNTHESIS IN RAT LEUCOCYTES

Abstract
Rat peritoneal leucocytes incubated with hydrocortisone (10 μg/ml) release a factor which inhibits prostaglandin generation. The steroid-induced inhibitor, which mediates the anti-phospholipase effect of anti-inflammatory steroids, may be a protein or a polypeptide since its formation is blocked by cycloheximide, a known inhibitor of protein synthesis.
