In this second volume in the series The Retroviridae, the readers are treated to up-to-date reviews on these viruses, which are found in a variety of animal species. The volume begins with important observations on the general fea­ tures of retrovirus entry into cells as determined by the viral envelope glyco­ proteins and the cell surface receptors (Chapter 1). Aspects of this virus-cell interaction form the basis for the variety of biologic effects associated with this virus family. A timely review of the oncogenic feline viruses is included next (Chapter 2). These viruses, along with the avian and murine retroviruses (Volume 1, Chapters 6 and 7), have provided valuable insight into cancer induction in other animal species, including humans. Two other major groups of retroviruses, the lentiviruses and the spuma­ viruses, are introduced in the present volume. Initially these groups, along with oncoviruses, were the three subfamilies in the Retroviridae. This com­ plex virus family has now been reclassified into seven separate genera (Vol­ ume 1, Chapter 2). Equine infectious anemia virus is the prototype for a lentivirus (Chapter 5). One of the first viruses discovered in nature (1904), it was only relatively recently recognized as a retrovirus. Lentiviruses are asso­ ciated primarily with immunologic disorders such as autoimmunity and AIDS (Chapters 3-5), but their association with neurologic disease is also well established (Chapters 4 and 5, and future volumes).

The books in this acclaimed series are the most detailed, up-to-date accounts of the field available. Volume 3 explores the oncogenic potential shared by retroviruses of different species, the widespread presence of retrovirues in nature, and the role of retroviruses in normal development and pathogenesis.

depth overview of the retrovirus family. I have greatly enjoyed and learned from this experience. Each chapter is an excellent introduction to the topic covered and provides a good foundation for further work in the field. Jay A.

This volume contains selected contributions from individuals who attended the Sec­ ond International Conference of the International Council for Global Health Progress (ICGHP) held at UNESCO in Paris, France, on January 15-17, 1996. This conference brought together experts in many disciplines that deal with the devastating diseases of cancer and AIDS with a focus on the concerns for quality of life. The ICGHP fosters mul­ ticultural and, multidisciplinary approaches to global health problems to help influence governments and other international health organizations to emphasize prevention and care of diseases and to understand their scientific, social, and cultural features. The Coun­ cil encourages the interchange of information on health problems and policy and supports educational funding for the public at large. Its objective is to effect diseases-free lives in the world community. Participants of the conference included scientists, sociologists, government leaders, physicians, health care providers, epidemiologists, religious leaders, company officials, ethicists, and philosophers. They examined and discussed the many variables involved in quality of life for people affected with cancer and with AIDS. The volume's text begins with introductory comments by officials attending the JCGHP conference. Subsequently, a chapter is dedicated to one aspect of quality of life, be it definition, scientific research, evolution, cultural changes, ethics, measurements, or other issues dealing with health care and treatment survival. The second part of the volume includes commentaries dealing with fi ve aspects of quality of life which merit consideration.
