The European Study Group for Cell Proliferation held its XVth Meet ing at Sundvolden, Norway, in September 1987. The program included a symposium on the cell kinetics of the in flammatory reaction, with invited speakers. This volume of Current Topics in Pathology contains the manuscripts submitted by the speak ers. Inflammation is a very broad area, and the cell kinetics of the inflammatory reaction comprises a large number of topics. A full cover age would fill more than one book. This volume therefore contains only a few of the important aspects of the cell kinetics of the inflammatory reaction. It is hoped that it will serve as inspiration for further research in this important area. Inflammatory diseases are even more important than cancer, and there is a great need for a more detailed information about inflammation.
