Metabolic Arrest and the Control of Biological Time

Freshwater turtles and goldfish can survive for several days without oxygen, some diving turtles for several months; hibernating animals can exist without food for long periods; others can survive extreme conditions such as desiccation, freezing, and thawing. These creatures are, in effect, self-sustaining life-support systems, with a mysterious ability to regulate their own metabolisms.

These capabilities raise important questions, which Hochachka and Guppy explore in this seminal new book. What mechanisms turn down (or off) cell metabolism and other cell functions? How does an animal such as an opossum know when to activate mechanisms for slowing or stopping tissue and organ functions? How does it know when to turn them on again? How extensive is metabolic arrest as a defense against harsh environmental conditions? Can we decipher universal principles of metabolic arrest from available data? The lessons to be learned are of potentially great interest to clinicians, because the authors provide a theoretical framework in which to organize an attack on the all-too-practical problem of protecting tissues against hypoxia. Areas that may be influenced include research on cardiac arrest, strokes, acute renal failure, liver ischemia, lung injury, respiratory defense syndrome, claudication, shock, and organ transplant. Investigation of other metabolic arrest mechanisms may be similarly useful in both clinical and agricultural fields.

This is a pioneering book of great use to biomedical/clinical researchers and to biologists, biochemists, and physiologists generally.

Reviews

Hochachka has performed his survey with guile ... for the many who can't see the wood for the trees it provides an unintimidating and readable technical account of some very important physiological and biochemical phenomena.

This is an excellent book, which contains both material and insights useful to anyone interested in anaerobic life forms.

[Hochachka's] enthusiasm has led him to bring together a great diversity of material to make a coherent story. There is a point in everything he has written, and that is an unusual achievement for a work that is primarily about biochemistry, a subject prone to accumulation of disconnected facts ... what really makes this book so fascinating [is that] he puts the biochemistry into the whole picture of the physiology and life-style of the animals.
