These two volumes, entitled "Purine Metabolism in Man IV" con tain the paper presented at the "IV. International Symposium on Human Purine and Pyrimidine Metabolism," held in Maastricht (The Netherlands), June 1982. The proceedings of the three previous meet ings in Tel Aviv (Israel, 1973), Baden (Austria, 1976) and Madrid (Spain, 1979) were also published by Plenum Press. In the past few years interest in purine and pyrimidine metabo lism under normal and pathological conditions has been growing rapid ly. Apart from the more or less classical topics such as hyperuricae mia, clinical gout and urolithiasis, an increasing number of papers relating to other fields have been presented at successive meetings. Knowledge derived from the study of purine metabolism in relation to lymphocyte function, for instance, has opened up new possibilities for immunomodulation and leukaemia chemotherapy, with eventual conse quences for other types of cancer. At previous meetings there have been pointers implicating purine metabolism in relation to normal cardiac and skeletal muscle function. During the present meeting much new data on both issues have been re ported which indicate clear differences in the pathways of ATP metabo lism. The widening of the field of interest is also illustrated by the recent work on infectious disease: exploitation of the differences in purine metabolic pathways in certain parasites compared with those in human cells has resulted in new rationales for therapy being devel oped.

Gout and urie acid lithiasis are known to have affected mankind for thousands of years. It is only recently, however, that great progress has been made in the understanding of the processes involved in purine metabolism and its disorders in man. The key enzymes active in the various pathways of purine synthesis and degradation have become known and their properties are the subject of intensive study. Major contributions to the knowledge of normal purine metabolism in man have derived from the study of inborn errors in patients with purine disorders, specifically complete and partial hypoxanthine-guanine phosphoribosyltransferase deficiency. Mutations of other enzymes involved in purine metabolism are being discovered. A great step forward has been made in the treatment of gout with the introduction of uricosuric drugs and more recently of the hypoxanthine analogue allopurinol, a synthetic xanthine oxidase inhibitor. Furthermore, the complex nature of the renal handling of urie acid excretion, although still posing difficult problems, appears to approach clari fication.

These volumes contain the papers which were presented at the Third International Symposium on Purine Metabolism in Man held in Madrid (Spain) in June, 1979. The previous meetings in the series were held in Tel Aviv (Israel) and in Baden (Austria) in 1973 and 1976, respectively. The proceedings were also published by Plenum. Knowledge of the pathophysiology of the purines has developed greatly since the 1950's when it was mainly related to clinical gout, and it is now relevant to many fields of Medicine and Biology. These volumes include papers reporting new work on clinical gout and urolithiasis as well as on some of the subjects which have featured prominently in the previous volumes, including: regulatory aspects of the intermediary metabolism of purines and related com pounds, enzymology, methodology, and the results of mutations which affect purine metabolism. However, there have been many new develop ments during the last three years and the scope of the communications reflects not only increasing depth of knowledge, but also a widening of the field. This publication has clinical and fundamental impli cations for internal medicine, pediatrics, urology, biochemistry, immunology, genetics, and oncology.

The study of gouty arthritis has provided a common meeting ground for the research interests of both the basic scientist and the clinician. The interest of the chemist in gout began 1776 with the isolation of uric acid from a concretion of the urinary tract by the Swedish chemist SCHEELE. The same substance was subsequently extracted from a gouty tophus by the British chemist WOLLASTONE in 1797 and a half century later the cause of the deposits of sodium urate in such tophi was traced to a hyperuricemia in the serum of gouty patients by the British physician Alfred Baring GARROD who had also received training in the chemical laboratory and was therefore a fore-runner of many of today's clinician-investigators. The recent surge of progress in understanding of some of the causes of gout in terms of specific enzyme defects marks the entrance of the biochemist into this field of investigation. The identification of the first primary defect of purine metabolism associated with over-production of uric acid, a severe or partial deficiency of the enzyme hypoxanthine-guanine phospho ribosyltransferase was achieved less than a decade ago. The knowledge of the mechanism of purine over-production that it generated led shortly to the identification of families carrying a dominantly (possibly X-linked) inherited increase in the activity of the enzyme phosphoribosylpyrophosphate synthetase as a cause of purine over-production. Yet this is only a start as these two types of enzyme defects account for less than five per cent of gouty patients.

The Fifth International Symposium on Human Purine and Pyrimidine Metabolism was held in San Diego, California (U. S. A. ) in July and August of 1985. Previous meetings in this series were held in Tel Aviv (Israel), Baden (Austria), Madrid (Spain) and Maastricht (The Netherlands). The proceedings of each of these meetings were published by Plenum. The next meeting will be in Japan. This Symposium differed from those that went before in that it per mitted us to honor Dr. J. E. Seegmiller, Professor of Medicine at the University of California San Diego, for his many contributions to our understanding of purine metabolism in man. This publication is dedicated as a Festschrift to Jay. Dr. Richard W. E. Watts delivered the keynote address outlining in scholarly fashion the history of Dr. Seegmiller's accomplishments in research on purine metabolism and the great number of currently active scientists in this field who have worked with him. This address is published as the first contribution to Volume I. Dr. Dewitt Stetten, Jr. , was scheduled to be the speaker at our banquet. Unfortunate ly, he could not be with us. Dr. Seegmiller has written an appreciation of Dr. Stetten and his contributions to our field, and this has been pub lished following Dr. Watts' paper. The growth of knowledge in purine and pyrimidine metabolism continues to be exponential. The variety of subjects included in these volumes is impressive.
