Advances which have been made in the field of lipid chemistry and bio chemistry during the last ten years mainly are the results of progress in metho dology. The introduction of isotopic and chromatographic techniques has not only enriched our knowledge of normal lipid metabolism but has also greatly enhanced the understanding of the various lipidoses. This is well illustrated by a comparison of the contents of the present monograph with those of my 1955 review in Handbuch der Inneren Medizin (Springer). In addition to better information about the classic lipid thesaurismoses Nie mann-Pick disease, Gaucher's disease and Tay-Sachs disease, the number of hereditary lipid storage diseases has increased considerably through the recogni tion of new syndromes such as metachromatic leukodystrophy, Fabry's disease, Refsum's disease (heredopathia atactica polyneuritiformis), a-p-lipoproteinemia, and Tangier disease. Conversely, disorders such as Hand-Scholler-Christian disease which has been considered a lipidosis up to 1958 (THANNHAUSER) must now be differentiated from the hereditary disturbances of lipid metabolism. Essential hyperlipemia which at one time seemed to be a well defined entity has now been recognized to consist of a number of subgroups, whose pathogeneses appear to be quite different, and whose classification is by no means definite. Similar problems exist for "essential hypercholesterolemia". Since the knowledge of today is the key for the solutions of tomorrow, we are fortunate that the chapters on lipidoses are supplemented by a comprehensive account of lipid chemistry and biochemistry which has been coordinated by W. STOFFEL.

Methods of Enzymatic Analysis, Volume 2 reviews developments in the determination of enzyme activity, including advances in assay techniques. It discusses the principles on which measurements of enzymes are based, with each chapter including equations and each method consisting of the pipetting protocol. This volume is divided into four parts, each discussing a group of enzymes and their determination. Part I focuses on oxidoreductases, such as sorbitol dehydrogenase, lactate dehydrogenase, malate dehydrogenase, isocitrate dehydrogenase, 6-phosphogluconate dehydrogenase, xanthine oxidase, and glutamate dehydrogenase. Part II is concerned with transferases ranging from ornithine carbamoyltransferase and transamidinase to transketolase, transaldolase, UDP-glucuronyltransferase, glutamate-pyruvate transaminase, and phosphotransferases. Part III discusses hydrolases including esterases, glycoside hydrolases, peptidases, and proteinases, whereas Part IV looks at lyases, isomerases, and ligases, such as fructose-1, 6-diphosphate aldolase, 1-phosphofructoaldolase, glucosephosphate isomerase, and tetrahydrofolate formylase. This book is a valuable resource for biochemists as well as students and researchers working in the field of analytical biochemistry.

For centuries men speculated about the process of gastric digestion, but Iate in the eighteenth and early in the nineteenth centuries physiologists, both physicians and laymen, began to accumulate experimental evidence about its nature. At the same time, others discovered that the stomach is capable of secreting a strong mineral acid, and the questions of how that secretion is produced and how it is controlled became enduring problems. A Iittle later, the discovery that an acid extract of dead gastric mucosa is capable of digesting meat put the study of gastric secretion and digestion on a firm mechanistic foundation. From that time to the present, physi ologists have assiduously investigated gastric secretion and digestion, with the result that knowledge ofthose topics is as comprehensive and penetrating as isthat about other physiological processes. In addition, that knowledge is the basis of discrimi nating and effective clinical practice. I have described the experimental study of gastric secretion and digestion for two reasons. The firstisthat the successes and some ofthe failures ofphysiologists over two centuries are important parts of intellectual history that deserve to be recorded. The second is that some of those who use the accumulated knowledge every day are curious about its genesis. I assume that my readers have the technical knowledge to understand what I have written. If my account does not fully satisfy their curiosity, I have provided references that will open the path to further study.

Volume XXV of the Handbook of Experimental Pharmacology series entitled "Bradykinin, Kallidin, and Kallikrein" was published in 1970. My aim in editing this volume of the series is not to replace, but to update the 1970 edition. During the decade preceding the publication of Vol. XXV, the existence of kinins and kallikreins gained acceptance, the protein components of the system were purified and characterized and the peptides were synthesized. Even after these accomplish ments, interest in the subject has not abated, but has increased substantially. We have learned a great deal about the role that components of the kallikrein-kinin system play in other systems and about the immensely complex and intricate inter actions in blood. Directly or indirectly, kallikrein and kinins affect the coagulation of blood, the activation of complement, and the generation of angiotensin. Kinins release or modulate the actions of other agents, including prostaglandins, histamine, and catecholamines. Inhibitors of kallikrein or kininase II are employed, for example, in extracorporeal circulation or in hypertension. Kallikrein, kinins, and kininases, present in urine, were described first in 1925 and 1954, but have been ignored for decades. These substances are now studied extensively because of their possible role in blood pressure regulation. The evidence that kinins have a metabolic function is also increasing. The abundance of active components of the system in genital organs suggests a role in the fertilization process. The book is organized into chapters which bear upon these issues.

Bradykinin is frequently referred to as an elusive substance; the editor of a comprehensive volume dealing with kinins thus has a difficult task. The com plexity of the issues calls for a large number of contributors who approach the topics from the various angles that are dictated by the sometimes divergent views of the individuals. The editor saw no reason to prescribe the mode of presentation, which was left to the authors and accounts for the variety of approaches. Contributors from nine countries were asked to participate in the volume. The chapters were organized to present, first, the history of the discoveries and methods of approach to kinin research. Then follows a discussion of the enzymes that release kinins, their substrates, and other enzymes that inactivate the peptides. If the release of kinin is important, then the inhibition of the releasing enzymes is of obvious interest and is described. Since the measurement of kinin ogen levels in blood has been frequently used as an indicator of kinin liberation, in addition to a separate chapter, kininogens are also mentioned where the functions of kinins are discussed. The conclusions drawn from establishing structure-action relationships for many analogs and the actions of kinins are indicated and summarized.

Sixteen years have passed since the first Leiden Conference on Mononuclear Phagocytes. That first meeting led to new nomenclature, i. e. , the Mononuclear Phagocytes System (MPS), which was published in the Bulletin of the World Health Organization (R. van Furth, et aI. , Bull. WHO, 1972, 46: 845-852). The paradigm of the MPS has the advantage of being much more consistent than the Reticuloendothelial System (RES) (L. Aschoff, Ergebn. Inn. Med. Kinderheilk. 1924, 26:1), because cells with similar characteristics can be classified in the same category. The essence ota new concept is, according to Popper, that it must be susceptible to falsification. This has been attempted several times for the MPS by those who adhere to the RES. However, in biology no one can be certain of truth. Any theory must be based on experimental observations and/or theoretical consider ations and both should be presented in such a way that others can try to refute it, then or later. One may have a theoretical or a pragmatic preference for a theory which at a given time is regarded as possibly truc, but later it may be shown to be false. In other words, what we present in this volume is regarded as true at this moment, but others may consider it as not true and try to disprove it. Controversies often stimulate new research.
