title: Effects of serum albumin, indomethacin and histamine H1-antagonists on Paf-acether-induced inflammatory responses in the skin of experimental animals and man.
abstract: Cutaneous responses to synthetic platelet activating factor (Paf-acether) have been studied in guinea-pig and human skin. Intradermal injection of Paf-acether elicited an acute inflammatory response in guinea-pig skin (assessed by means of radioisotopic techniques) and acute oedema formation in human skin (assessed by means of weal volume and flare area). Acute inflammatory responses in guinea-pig and human skin are potentiated by the presence of serum albumin, a phospholipid carrier. Acute inflammatory responses induced by Paf-acether in guinea-pig and human skin are not significantly affected by concomitant administration of the cyclo-oxygenase inhibitor, indomethacin. Acute inflammatory responses induced by Paf-acether in guinea-pig and human skin are not significantly affected by concomitant administration of the cyclo-oxygenase inhibitor, indomethacin. Acute inflammatory responses induced by Paf-acether in guinea-pig and human skin are slightly modified by the H1-receptor antagonists, mepyramine and chlorpheniramine. These results indicate that the acute inflammatory response induced by Paf-acether is independent of cyclo-oxygenase products of arachidonic acid and that histamine release has a minor contribution to the inflammatory response induced by Paf-acether.
