Increasingly, basic knowledge about connective tissue has relevance to pathophysiology of disease. This book attempts to emphasize this concept. It is a success in parts, and a failure in others.Pérez-Tamayo is a pathologist who understands well the chemical complexities of the study and evaluation of collagenases. His chapter on "Collagen Degradation and Resorption, Physiology and Pathology" is a well interpreted review of . . .
