Advances in Molecular Toxicology features the latest advances in all of the subspecialties of the broad area of molecular toxicology. Toxicology is the study of poisons, and this series details the study of the molecular basis by which a vast array of agents encountered in the human environment and produced by the human body itself manifest themselves as toxins. Not strictly limited to documenting these examples, the series is also concerned with the complex web of chemical and biological events that give rise to toxin-induced symptoms and disease. The new technologies that are being harnessed to analyze and understand these events will also be reviewed by leading workers in the field. Advances in Molecular Toxicology will report progress in all aspects of these rapidly evolving molecular aspects of toxicology with a view toward detailed elucidation of both progress on the molecular level and on advances in technological approaches employed. * Cutting-edge reviews by leading workers in the discipline * In-depth dissection of molecular aspects of interest to a broad range of scientists, physicians and any student in the allied disciplines * Leading edge applications of technological innovations in chemistry, biochemistry and molecular medicine

Molecular toxicology is on the way to setting a new standard in toxic risk assessment, with the powerful help of concepts and methods developed in the fields of molecular and cellular biology. The methods of molecular toxicology are endowed with qualities not always secured in more traditional approaches to toxicity assessment. These methods are easily standardized, reliable, reproducible and require only tiny amounts of the xenobiotic. They are much simpler, faster and less costly than current tests on animals and can be implemented with modest laboratory resources. This volume of Advances in Molecular Toxicology represents a collection of invited papers presented at the First European Workshop on Molecular Toxicology in Sophia Antipolis, France, The book covers 8 selected topics in molecular toxicology. The first two are devoted to ''physics'', dealing respectively with advanced instrumentation enabling location and quantification of xenobiotics in cells and organs with ultimate precision, and computer-assisted assessment of risk (QSAR). A comprehensive and up-to-date survey of molecular toxicology in the pharmaceutical industry is contributed by a pioneer in this field. The third section addresses the effect of xenobiotics on cell-cycle actors. Sections 4--6 deal with molecular toxicology in skin, kidney, nerve, liver and pancreatic cells. The last two sections describe methods to probe DNA damage and repair, and immunotoxicity.

Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants, so widespread that it is impossible for anyone to avoid exposure to them. They are the products of partial combustion, and exposure comes from the fossil fuels that we use to drive our cars, cook our food, warm our home, and fuel our industry. Other exposure comes from tobacco smoke and oil spills. PAHs are responsible for more cancers, primarily lung cancers, than any other carcinogen. The most studied PAHs are unsubstituted multi-ring structures. These compounds are not DNA reactive, and must be modified to become carcinogenic. Metabolic pathways modify PAH during the detoxification process. Three pathways have been extensively documented: the diol-epoxide pathway, the radical cation pathway, and the o-quinone pathway. Some PAHs are generated during combustion in oxygenated forms, usually as quinones. Quinones also form as PAHs are exposed to sunlight, for example, in an oil spill. These metabolic products damage DNA through distinct mechanisms: diol epoxides form bulky adducts with DNA, radical cations form depurinating adducts and quinones undergo futile redox cycling to generate reactive oxygen. Here, we discuss the evidence for these pathways in PAH carcinogenesis.

Auf Einladung der Deutschen Forschungsgemeinschaft (DFG) fand am 9. und 10. März 2000 ein Rundgespräch über heutige und künftige Möglichkeiten des Biomonitoring in Arbeits- und Umweltmedizin statt. Das Biomonitoring hat nicht zuletzt durch die unmittelbare Umsetzung der Arbeitsergebnisse der Senatskommission zur Prüfung gesundheitsschädlicher Arbeitsstoffe in geltendes Recht durch die deutsche Arbeitsschutzgesetzgebung in den letzten dreißig Jahren in Deutschland ein hohes Niveau erreicht. Das vorliegende Buch führt die Expertise verschiedener Fachdisziplinen von der Toxikologie, Arbeitsmedizin, Immunologie und Humangenetik bis hin zur Analytik und Epidemiologie zusammen. Hierbei wird die diagnostische Aussagekraft von zytogenetischen Parametern sowie von biochemischen und biologischen Effektmarkern für die Prävention von schadstoffbedingter Erkrankungen ausführlich erörtert. Das geführte Rundgespräch hat somit einen ersten Gedankenaustausch ermöglicht, aus dem sich künftige Forschung entwickeln soll, um die führende Rolle Deutschlands auf diesem wichtigen und sich dynamisch entwickelnden Forschungsgebiet zu halten.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfängen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen für die historische wie auch die disziplingeschichtliche Forschung zur Verfügung, die jeweils im historischen Kontext betrachtet werden müssen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.

Tailored to the needs of scientists developing drugs, chemicals, cosmetics and other products this one-stop reference for medicinal chemists covers all the latest developments in the field of predictive toxicology and its applications in safety assessment. With a keen emphasis on novel approaches, the topics have been tackled by selected expert scientists, who are familiar with the theoretical scientific background as well as with the practical application of current methods. Emerging technologies in toxicity assessment are introduced and evaluated in terms of their predictive power, with separate sections on computer predictions and simulation methods, novel in vitro systems including those employing stem cells, toxicogenomics and novel biomarkers. In each case, the most promising methods are discussed and compared to classical in vitro and in vivo toxicology assays. Finally, an outlook section discusses such forward-looking topics as immunotoxicology assessment and novel regulatory requirements. With its wealth of methodological knowledge and its critical evaluation of modern approaches, this is a valuable guide for toxicologists working in pharmaceutical development, as well as in safety assessment and the regulation of drugs and chemicals.

Dieser Band zeigt die sensationell anmutenden Fortschritte der Pyrethrum Chemie, die für Forschung, Industrie und Anwender neue Aspekte eröffnet. Vor allem englische und japanische Chemiker haben in fast dreißigjähriger, intensiver Arbeit, ausgehend von den natürlich vorkommenden Insektiziden aus Pyrethrum pflanzen und bereits bekannten synthetischen Abwandlungsprodukten, wirk samere und beständigere Wirkstoffe gewinnen können. (Eine Übersicht des Forschungsstandes bis 1967 findet sich in Band I (Claussen).) Nach dem Bekanntwerden der ersten wesentlichen Erfolge durch Elliot in England ist die Forschung von fast allen großen Chemiefirmen und Forschungsinstituten auf genommen worden. Dr. K. Naumann (Bayer AG) hat gedrängt, doch möglichst vollständig die umfangreichen Forschungsergebnisse sowie die zahlreichen Versuchs- und Han deisprodukte zusammengestellt. Er zeigt, wie der Weg zu neuen Wirkstoffen über komplizierte Synthesen mit zahlreichen Zwischenstufen führt. Die höchst wirksamen Verbindungen lassen auch Vielstufen-Synthesen noch aussichtsreich erscheinen. Der Beitrag demonstriert nicht nur den hervorragenden Stand der chemischen Forschung, sondern auch den großen Aufwand, der dafür nötig ist. Nachteile früherer Verbindungen, wie die geringe Stabilität unter atmosphäri schen Bedingungen, konnten ausgeschaltet werden, ohne daß Wirkung und rascher Wirkungseintritt verloren gingen. Leider mußte bei einigen Verbindungen eine höhere Toxizität in Kauf genommen werden, doch wegen der guten Abbaueigen schaften gibt es keine Rückstandsprobleme. Diese Übersicht macht deutlich, wie es der rein chemischen Insektizid-Forschung immer wieder gelingt, entscheidende Fortschritte zu erzielen. Februar 1981 R. Wegler Inhaltsverzeichnis A.
