Effects of a human plasma fraction on leucocyte migration into inflammatory exudates

Abstract
A fraction prepared from normal human plasma inhibits the migration of polymorphonuclear and mononuclear leucocytes into inflammatory exudates produced by the intrapleural injection of carrageenan or turpentine and by the subcutaneous implantation of polyvinyl sponges in the rat. The mechanism of the effect does not involve complement depletion.
