The international symposium "New Trends in Allergy", held in Munich from July 13 to 15, 1990, brought together for the third time since 1980 some of the most experienced researchers working in the field of allergy. This volume comprises the papers presented at this meeting. All over the world, and not merely in the industrialized countries, allergy is becoming a cause of evermore serious diseases. In recent years, research in the field of allergy has provided numerous impor tant and fascinating results extending our knowledge considerably. Despite the new insights into basic mechanisms of allergic reactions, improved diagnostic methods, and new therapeutic approaches, how ever, many questions remain to be answered, including: Are allergies really increasing in frequency? If so, what are the reasons? Especially, does environmental pollution playa role? Which factors influence IgE synthesis? Can the IgE immune response be switched off? Does the nervous system interact with allergic reactions? If so, what are the mechanisms? Are new approaches in allergy prophylaxis and allergy therapy effi cient? What measures have proven useful and deserve to be employed in daily practice? In this volume, these questions and other current topics are dealt with. As each issue is covered by authors competent in the respective fields, the result is an extensive and critical review of the state of the art. Going through these papers, one comes to the conviction that allergy research is a multifacetted, explosively expanding, most stimulating field of work.
