Assessment of plasma leukotriene and prostaglandin levels during adjuvant arthritis and kaolin-induced paw oedema in rats.
Plasma levels of some arachidonic acid metabolites were investigated in acute and chronic models of inflammation in rats. As a model of chronic inflammation, adjuvant arthritis in rats induced by the injection of Freund's complete adjuvant, and as an acute model for inflammation, kaolin-induced paw oedama were used. Plasma leukotriene(LT) C4-like and prostaglandin(PG) E2-like activities were quantitated by bioassay in guinea-pig ileum and rat stomach fundus respectively. In the course of adjuvant arthritis, plasma levels of LTC4- and PGEi2-like activities were increased. Plasma LTC4-like activity reached a maximum within 3 weeks, while PGE2-like activity reached a maximum 10 days after adjuvant injection. In the early phase of adjuvant arthritis, levels of both LTC4- and PGE2-like activities were found to be low but both activities were increased in the late phase of inflammation.
期刊介绍：
The role of lipids, including essential fatty acids and their prostaglandin, leukotriene and other derivatives, is now evident in almost all areas of biomedical science. Cell membrane behaviour and cell signalling in all tissues are highly dependent on the lipid constituents of cells. Prostaglandins, Leukotrienes & Essential Fatty Acids aims to cover all aspects of the roles of lipids in cellular, organ and whole organism function, and places a particular emphasis on human studies. Papers concerning all medical specialties are published. Much of the material is particularly relevant to the development of novel treatments for disease.
