title: Purification and characterization of an anti-inflammatory factor (AIF) from bovine serum.
abstract: An anti-inflammatory factor (AIF) was highly purified from normal bovine serum. The purified AIF was a polysaccharide which was formed from a low molecular substance Pro-AIF by macromolecularization. AIF showed potent inhibitory activities against carrageenin induced edema in rats and PMN-leucocyte chemotaxis. It showed no inhibition in cutaneous reaction with serotonin, bradykinin or a mediator releaser compound 48/80. No inhibition was also observed in thermally induced pain, reversed passive Arthus reaction and adjuvant polyarthritis in rats. With these results, the role of AIF in inflammation was discussed.
