Book Description
Interest and research in urinary enzymology were incited about three decades ago by reports that urinary enzymes are elevated in diseases of the kidney and urinary tract. Of the more than 40 hydrolases, oxidoreductases, transferases, and lyases identified in human and animal urine, only ten or so are being used as diagnostic indicators. Recognition of the quantitative distribution of enzymes in the various anatomical and functional parts of the nephron and advances in our understanding of the handling of proteins by the kidney have made it possible to associate urinary enzyme activity patterns with physiological and pathophysio logical functions of the nephron. Confidence in the diagnostic value of urinary enzymes is not unanimous among clinicians and among scientists. The main reason for the difference in opinion may well be that the variability in data exceeds the variability one is accustomed to in the diagnostic enzymology of blood plasma enzymes. In contrast to plasma enzymes, which are protected by an "enzyme friendly" milieu, enzymes released into the urine encounter an "enzyme hostile" environ ment: no or little protective protein, variable pH, variable volume, variable metabolite and salt concentrations, variable concentrations of enzyme in hibitors. Through advances in methodology some of these factors can now be controlled; standardization of urine collection periods and preanalytical treat ment are as important as optimization of assay methods.

Book Description
Diseases of the kidney, bladder, and prostate exact an enormous human and economic toll on the population of the United States. This book examines prevention of these diseases through the development of reliable markers of susceptibility, exposure, and effect and the promise that new technologies in molecular biology and sophisticated understanding of metabolic pathways, along with classical approaches to the study of nephrotoxicants and carcinogens, can be developed and prevention of the diseases achieved. The specific recommendations included in this book complement those made in the previous three volumes on biomarkers, Biologic Markers in Reproductive Toxicology (1989), Biologic Markers in Pulmonary Toxicology (1989), and Biologic Markers in Immunotoxicology (1991).

Book Description
Nephrotoxicity : Otoxicity of Drugs. Ce livre rassemble les textes des communications présentées au symposium de Rouen (mai 1981) ayant pour thème l'étude de la néphrotoxicité des antibiotiques. La majeure partie de l'ouvrage est réservée à la néphrotoxicité des aminoglycosides. Sont détaillés les aspects morphologiques, les résultats d'études autoradiographiques, d'études de fractionnement cellulaires permettant l'analyse du comportement des mitochondries ou des lysosomes. Une large part est réservée aux variations de multiples enzymes urinaires excrétées sous l'action des médicaments. Le rôle de nombreux facteurs est largement discuté : influence des doses injectées, du rythme d'administration, de la durée du traitement, de l'âge, de l'existence d'une néphropathie antérieure. À la lecture des différentes études présentées, le clinicien pourra juger des différences de potentiel néphrotique des antibiotiques qui lui sont proposés pour le traitement des infections sévères. La place consacrée à l'otoxicité des aminoglycosides est plus restreinte mais les études de variations de potentiels pour détecter les signes d'otoxicité, les études de pharmacocinétique des aminogly¬cosides sont des contributions fort intéressantes et très originales.
