Initially, because of the inadequate sensitivity of devices and other limitations, only major venom components of the dominant species were studied. However, in last two decades, increased sensitivity of devices and the development of new techniques, such as transcriptomics and proteomics techniques, have permitted us to analyze the structures and functions of rare species and to identify novel minor components. As a result, the number of venom components identified is increasing dramatically and the physiological functions of each component is more deeply understood. The scope of this book provides the readers an updated and comprehensive presentation on snake venoms. The subjects are divided into six sections, starting with the overview of snake venom compositions in Malaysian species, followed by description of enzymes and enzyme inhibitors contained in snake venoms. Also discussed are the effects of snake venom on cellular receptors, ion channels, blood, and lymph, as well as cytotoxic and antimicrobial molecules present in snake venoms. The last section covers the clinical consequences of envenomation and the management of snakebites using antivenins.

Hidetoshi Inagaki is senior researcher at the National Institute of Advanced Industrial Science and Technology, in Japan, since 2001, working on the bioactive peptides of venomous animals, such as snakes and ants. During that time, from April 2006 to March 2007, he worked at CSTP (Council for Science and Technology Policy) on the "Guidelines on the Derivation and Distribution of Human Embryonic Stem Cells" and other science policies. From April 1994 to March 2001, Inagaki was a researcher at the National Industrial Research Institute of Nagoya, Japan. Inagaki received his Ph.D. from Nagoya University, Japan, in 1994, with time spent in Beth Israel Hospital, Boston, United States, from August 1991 to March 1992. He was also a graduate (April 1989--March 1991) and an undergraduate (April 1984-March 1989) at Nagoya University, Japan. For last five years, his research group has been working on the directed evolution of bioactive peptides. Using directed evolution, the group could generate agonist and antagonist like molecules of receptors, and enzyme inhibitors.

Carl-Wilhelm Vogel received his M.D. degree and Ph.D. degree in biochemistry from the University of Hamburg in Germany. For three-and-a-half years, Dr. Vogel was a postdoctoral research fellow in molecular immunology at Scripps Clinic and Research Foundation in La Jolla, California. He completed a medical internship in Germany and four years of residency training in clinical pathology at Georgetown University in Washington, D.C., and at Indiana University/Purdue University in Indianapolis. He is a licensed physician and a board-certified clinical pathologist both in the USA and Germany. He was on the faculty of Georgetown University School of Medicine for approximately nine years in the Departments of Biochemistry and Molecular Biology and Internal Medicine, and a member of the Lombardi Cancer Center, before assuming the chairmanship of the Department of Biochemistry and Molecular Biology at the University of Hamburg in 1990. In 1999 he became Director of the Cancer Research Center of Hawaii at the University of Hawaii, a position he held for about a decade. He currently is a full professor at the same institution. His research interests have been in the area of basic biomedical research with particular emphasis on the immunological aspects of cancer as well as the development of novel therapeutic concepts for diseases with complement pathogenesis, based on the complement-depleting activity of cobra venom factor. His research has been supported continuously by peer-reviewed grants since 1983, mainly from the National Institutes of Health. He is the author of well over 100 publications and patents.
