This volume constitutes, in part, the proceedings of the Hong Kong Conference on Eicosanoids and Other Bioactive Lipids in Cancer, Inflammation, and Radiation Injury held in Hong Kong in October 1995. It contains papers by the symposium speakers, as well as poster contributions from researchers in this field. Since the discovery of PROSTAGLANDIN-LIKE’ substances 60 years ago. much has been learned. EICOSANOID is the new term that is used to include prostaglandins. thromboxanes, leukotrienes, lipoxins, isoprostanes, depoxilins, hydroxy acids, epoxy and hydroperoxy fatty acids. The conference focussed on recent development in underatanding the role of EICOSANOIDS in inflammation, cancer, and radiation damage. At the confer- ence, we also highlighted advances in newly developing areas such as NO,
A POP- TOSIS and ANANDAMIDE. The discovery of the structures of genes that encode several key enzymes and receptors of the Eicosanoid cascade, has allowed us to include reports in the Alteration of the Gene Expression section that reflects the most recent de- velopments in regulation for PGH-synthase and lipoxygenases. The editors are convinced that this volume will be an up-to-date and useful reference for investigators in both basic and clinical research.
