The International Society for Arterial Chemoreception (ISAC) was founded in August 1988 during the 9th International Symposium on Arterial Chemoreception which was held at Park City, Utah, USA. ISAC was established with the aim of providing a framework to support the increasing number of investigators from a wide variety of disciplines (anatomists, pathologists, respiratory physiologists and clinicians, high altitude physiologists, biochemists, biophysicists, physiologists and pharmacologists) who share a common interest in arterial chemoreception. ISAC took over the co-ordination of the international chemoreceptor meetings, with the membership deciding the venue for forthcoming meetings. During the Park City symposium Dublin was selected to host the 1993 meeting, under the Presidency of Professor Ronan O'Regan. The 12th International Meeting on Arterial Chemoreception, which was held in Dublin in August 1993, was acclaimed as a great success by all those present. The delegates not only shared in a wide-ranging feast of chemoreceptor based science, they had plenty of opportunity during the meeting for renewing acquaintances and establishing new friendships. The location for the meeting at University College Dublin's modem Belfield campus helped to promote such interaction, and the social programme was outstanding.

This volume records the papers presented in Warsaw on the meeting of the International Society of Arterial Chemoreception (LS. A. C. ) organized as a Satellite Symposium of the XXXI International Congress of the Union of Physiological Sciences (I. U. P. S. ) in Helsinki in July 1989. It is a 30 years old tradition to hold periodically international meetings on recent developments in chemoreceptor research and to exchange information between those of us interested in chemoreception. The first meeting was organized by B. B. Lloyd in Oxford in 1959. Later on, similar international meetings were held at irregular intervals. In 1966, R. W. Torrance organized the second meeting again in Oxford. In 1973, the third meeting was organized in Bristol (U. K. ) by M. J. Purves. In 1974, a fourth meeting combined with the XXVI I. U. P. S. Congress in Delhi was organized by A. S. Paintal in Srinagar (Kashmir, India). In 1976, H. Acker organized the fifth meeting in Dortmund (F. R. G. ), and in 1979, C. Belmonte in Valla dolid (Spain) organized the sixth international meeting commemorating the 50th anniversary of Fernando de Castro publishing his classical work on the structure and possible function of the carotid body. In 1982, the seventh meeting was due to D. J. Pallot in Leicester (U. K. ), in 1985 - the eighth one due to A. J.
