The intraplantar injection of PAF-acether (PAF), induced acute oedema in the rat paw, and desensitized it to subsequent challenges with the same agonist, but not to serotonin. The desensitization was maximal (up to 80% of initial response) after seven consecutive daily injections. In this condition, PAF-induced oedema of the contralateral paw was maintained. The analogue 2-methyl carbamate-PAF (2MC-PAF) was more effective than PAF as a desensitizing agent. Furthermore, the PAF-desensitized paw was refractory to challenges with 2-MC and vice-versa. PAF-acether, but not serotonin-induced rat paw oedema was inhibited by previous intravenous injection of PAF. Intravenous injections of serotonin were also effective in inhibiting selectively serotonin-induced paw oedema, but it was not possible to induce desensitization by repeated intraplantar injections of serotonin. Desensitization to PAF or the pre-treatment with the PAF antagonist BN 52021 did not block the edematogenic response induced by carrageenan.
