The integument plays an important role in the survival of meta zoans by separating and protecting them from a hostile environ ment. Its function ranges from protection against injury and in fection; partlcipation in the regulation of body temperature and water balance, to respiratory activity, monitoring of the environ ment and production of signals related to behaviour. All these result from specific structural, biochemical and physiological properties of intra-and extracellular components of the integu ment. Thus its characterization can be best accomplished by a multidisciplinary approach with authors specialized in different fields of science. This multi-author book, in two volumes, provides an up-to date survey of the literature. The first volume deals with the integument of invertebrates, the second with that of vertebrates, both organized primarily on a phylum basis. As the level of knowledge on the integument of phyla differs considerably, the information provided is correspondingly either limited or con densed. For some of the smaller groups of invertebrates little information is available, as often only a few electron micrographs are to be found in the literature; on the other hand, from the large body of knowledge existing for vertebrates, particularly for mammals, no complete overview can be provided, but publica tions giving access to further information have been reviewed critically.

An authoritative, extensively illustrated clinician's textbook, The Biology of the Skin is written expressly for practitioners and residents in dermatology, plastic surgery, and otolaryngology. Essentially an expansion of the editors' and contributing authors' popular "Structure and Function" course given annually at the meetings of the American Academy of Dermatology, the book teaches skin biology in the context of practical clinical settings. This book covers the basic biology of the skin, how the skin functions, effects of the environment, the molecules that direct cutaneous function, genetic influences, and methods in cutaneous research. The Biology of the Skin provides a selective review of all biologic processes involving the skin and will foster an appreciation of how the skin works based on our knowledge of the basic science of skin structure and function in the 21st century.

The vertebrate integument arose about 450 million years ago as an ‘armour’ of dermal bony plates in small, jawless fish-like creatures, informally known as the ostracoderms. This book reviews the major changes that have occurred in the vertebrate integument from its beginnings to the present day. Critical questions concerning the origin, structure and functional biology of the bony integument are discussed and intrinsically linked to major steps in vertebrate evolution and phylogeny—the origin of jaws and the origin of teeth. The discussions include the origins of mineralization of major vertebrate skeletal components such as the dermatocranium, branchial arches and vertebral column. The advances that led to the origin of modern fishes and their phylogenetic development are reviewed and include the evolution of fins and replacement of the bony plates with several types of dermal scales. The evolution of reptiles saw a major transformation of the integument, with the epidermis becoming the protective outermost layer, from which the scales arose, while the dermis lay below it. The biological significance of the newly-evolved β-keratin in reptilian scales, among the toughest natural materials known, is discussed in the context of its major contribution to the great success of reptiles and to the evolution of feathers and avian flight. The dermis in many vertebrates is strengthened by layers of oppositely oriented cross-fibres, now firmly entrenched as a design principle of biomechanics. Throughout the book conventional ideas are discussed and a number of new hypotheses are presented in light of the latest developments. The long evolutionary history of vertebrates indicates that the significance of the Darwinian concept of “survival of the fittest” may be overstated, including in our own mammalian origins and that chance often plays a major role in evolutionary patterns. Extensive illustrations are included to support the verbal descriptions. Professor Theagarten Lingham-Soliar is in the Department of Life Sciences at the University of KwaZulu-Natal.

Molecular Biology of the Skin: The Keratinocyte comprehensively reviews the major aspects of keratinocyte and epidermal differentiation, physiology, and pathology, primarily focusing on the molecular aspects. This exciting new resource discusses keratin genes, retinoic acid, and the use of transgenic animals in the study of dermatological pathology. The volume also highlights areas of genetic disease, new animal models to help in understanding dermatological disorders, and gene therapy using skin as a target. W.W. Franke, a pioneer in the study of the molecular biology of keratins, has written the foreword for the book. Molecular Biology of the Skin: The Keratinocyte is intended for use by dermatologists and basic researchers in cell and developmental biology. It will also be valuable for surgeons and other clinicians as well as researchers in gene therapy, virology, and pharmacology. * * Reviews keratinocyte (and epidermal) differentiation. physiology, and pathology, focusing on the molecular aspects * -Discusses keratin genes, retinoic acid, and the use of transgenic animals in the study of dermatalogical pathology * -Highlights genetic disease, new animal models, and gene therapy

Mention the words 'arthropod cuticle' to most biologists and they usually provoke a glazed expression. This is because the cuticle is commonly regarded as an inert substance. It is hoped that this book will dispel this fallacy. The study of cuticle in its proper context now involves many of the wider aspects of biology which are currently in vogue (e. g. how a hormone like ecdyson induces a specific enzyme like dopa decarboxylase; the unsolved major problem of cell gradient and polarity; the involvement of cyclic AMP in hormonal mechanisms; the extra cellular control of cuticular enzymes, of the mechanical proper ties of cuticle structural proteins, and of the orientation of fibrous molecules; and the relation of chromosome puffing to the synthesis of specific proteins). Studies on cuticle demand a variety of techniques, and examples of the following are illustrated in this book (fluorescence, phase contrast, polariza tion and Nomarski interference microscopy; infrared absorp tion; transmission and scanning electron microscopy; autora diography analyzed by electron microscopy; negative staining in the electron microscope; optical diffraction, high angle X-ray diffraction, low angle X -ray diffraction and selected area electron diffraction). I am well aware that the biophysical parts of this book are less incomplete than other aspects. A developmental biologist or a biochemist would have further elaborated other parts ofthe subject matter. Only one previous author, RICHARDS (1951)hasdevoted a book to arthropod cuticle.
