Foreword

With the help of our European and American colleagues and friends, we have been able to prepare this book on Biologic Rhythms in Clinical and Laboratory Medicine, which includes 20 parts consisting of 47 chapters on different aspects of chronobiology and medicine.

Parts I and II present six chapters on the basic concepts and the mechanisms of biologic rhythms, followed in Part III by a review of the appropriate methodology for their study. Part IV summarizes the large amount of data accumulated on the time-dependent changes in drug effects and side effects and in toxicology. Part V presents in four chapters observations on biologic rhythms beginning in preg­nancy and extending through childhood and development to old age. Part VI is dedicated to the rhythms in physical and mental performance and is followed in Part VII by the study of the adaptation of these rhythms during shiftwork and after transmeridian flights. In Part VIII is presented the physiology and pathophy­siology of sleep. Parts IX-XIX discuss biologic rhythms in different organ systems in health and disease, including aspects of physiology, pharmacology, and toxicol­ogy. The clinically important rhythm alterations found in certain psychiatric con­ditions, i. e., in affective disorders are presented in Part IX. The eight chapters in Part X are dedicated to the rhythms of multiple frequencies found in endocrine and metabolic functions. In Part XI, the biologic rhythms in hepatic drug metabo­lism are discussed which determine, in part, circadian and other variations in drug effects. Part XII describes the rhythmicity of the gastrointestinal system with its implications for ulcerogenesis and timed treatment. In Part XIII are discussed rhythms of the cardiovascular system, including hypertension, and in Part XIV rhythms in the respiratory system with the clinically important application to the treatment of bronchial asthma. Part XV presents rhythms in renal function and pathology. The chronobiology of the inflammatory reaction is presented in Part XVI. Biologic rhythms in hematology and immunology are presented in Part XVII and include, in addition to the large-amplitude rhythms of some of the formed elements in the peripheral blood, new data on the rhythmicity of the human bone marrow, which will be of considerable importance for the effects and/or side effects of the numerous drugs and other agents acting upon this com­plex and vital tissue. This part also includes observations on biologic rhythms in cell migration, in the immune response, and of the blood coagulation system with its implications for transient risk states for thrombosis or hemorrhage. Part XVIII presents first basic data on rhythms in normal and abnormal cell proliferation, then the endocrine regulations related to the cancerogenesis in endocrine respon­sive tissues, i. e., the breast, the rhythms in the appearance of tumor markers in the circulation, possibly representing periodic variations in tumor metabolism and, fi­nally, the opportunities provided by the rhythms of host and tumor to optimize chemotherapy by treatment timed according to the biologic rhythms of the host and/or the tumor. Epidemiologic aspects of chronobiology are presented in

VI Foreword

Part XIX in regard to physiologic events like birth and to chronopathology and death from numerous causes. Finally, the implication of biologic rhythms for lab­oratory medicine are discussed in Part XX including time-qualified reference values for high-amplitude rhythms and the tools to improve laboratory diagnosis by taking into account the principles of chronobiology.

In all these chapters, our purpose is to present to the reader, whether experi­enced in chronobiology or not, a general review of the role of biologic rhythms in the normal and abnormal function of different organ systems.

Each of the contributors is a known specialist in his or her field, and we would like to express our great appreciation for their participation in this didactic team­work. We hope that this book will interest the readers who wish to extend their familiarity with chronobiology and will provide the investigators in the study of bi­ologic rhythms a general overview of the field.
