[Platelet activating factor inhibits irritant-induced leukocyte migration into mouse peritoneal cavity].
The effect of platelet-activating factor (PAF) on the leucocytes accumulation into mouse peritoneal cavity, that induced by high-molecular irritants carrageenan and polyacrylic acid pentaerytritol (carbopol) was studied. It was found that injection of PAF into peritoneal cavity one hour before i.p. injection of the irritants did not change their effects. On the contrary the injection of PAF simultaneously with the irritants or 3 and 6 hours after these injections inhibited the leucocyte accumulation into the peritoneal cavity and/or these injections increased the leucocyte adhesion to the peritoneal covering. It was supposed that finding effects are mediated by the change of leucocytes adhesion under action of PAF.
