Neuware -Rabies-as in former times-is still today a major killer affecting man and animals especially in many tropical and sub-tropical countries of Asia, Africa and South America. Some 50,000 people and literally millions of animals suffer and die of this disease each year. This dramatic death toll and the enormous economic losses which ensue are nowadays un tolerable and no longer justified. Worldwide strategy for Rabies control has been established and the World Health Organization recently formulated an elimination programme for dog Rabies. Methods for wildlife Rabies control are also under way. For the realisation of control campaigns, careful epid emiological analysis is necessary. This involves: - antigenical characterisation of Rabies Virus Strains using monoclonal antibodies, - observation of foci, - follow-up of the front wave of the disease, - specific ecology of target populations and Rabies carrier species. The financial point of view of such campaigns has of course to be ascertained. It is for the first time ever that representatives and specialists of different biological disciplines from nearly 70 countries have had the opportunity in Tunis to discuss these important issues and to evaluate, on the basis of their own experimental results and personal epidemiological observations, the possibility of ultimate elimination of Rabies in tropical and sub-tropical countries and also to contribute their share for a better understanding of the natural history of this disease.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 808 pp. Englisch.

Neuware -The nitrates have remarkable clinical effects that have stood the test of time in the management of ischemic heart disease. What is unusual about this class of com pounds is that, after many years of clinical use, we are still exploring new avenues as to the vascular mechanisms of their effect, their applications in treating other clini cal conditions, and the development of products with more favorable pharmacoki netic properties. This volume represents the proceedings of a symposium held June 14-16, 1984, in Montreux. The papers were selected to explore the current state of knowledge re garding the mechanisms of action, pharmacokinetics, and clinical efficacy of ni trates. Particular attention has been given to newer studies utilizing the 5-mononi trate metabolite of isosorbide dinitrate, a drug whose pharmacokinetic properties may make it an important new agent in the treatment of angina and congestive heart failure. One of the benefits of an international meeting of experts sharing their views on an internationally used group of drugs is that differences in concepts and clinical practice become apparent and can be discussed. The Montreux forum made it clear that clinicians in North and South America and Europe have diverging views on how the nitrates should be used.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 336 pp. Englisch.

Neuware -Activation of the complement system gives rise to a number of molecular species which can interact with host-derived cells and regulate their function. This interaction is mediated through distinct cell surface complement receptors, and receptor engagement produces biologic responses which can either modulate host defense reactions or enhance inflammation. Although the first complement receptor was recognized more than 30 years ago [80J, detailed biochemical information concerning the receptors has only recently become available. Currently, eight distinct complement receptors are recognized. Five receptors (CRl, CR2, CR3, C3a receptor, and C3e receptor) react with various regions on C3 while the other receptors display specificity for Clq, C5a, or Factor H. This chapter focusses on the chemistry of the various ligands and receptors and discusses the biologic activities which arise as a result of receptor-ligand interaction. II. CIQ Receptor A. The Ligand Clq is the recognition molecule of the classical complement pathway [reviewed in 20, 130]. In serum, it is part of a calcium-dependent penta molecular complex containing one molecule ofClq and two molecules each of the pro enzymes Clr and CIs. During classical pathway activation, the macromolecular complex becomes associated with the activator through the Clq subcomponent. Bound Clq undergoes a conformational change and induces the proteolytic autoactivation of Clr which in turn effects the proteolytic activation of CIs. This process is controlled by the Cl inhibitor (ClINH) which binds irreversibly to activated Clr and CIs, and inhibits their enzymatic activities.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 484 pp. Englisch.
