The cytochemical bioassay system was described in a short abstract in 1971, and more fully, in the cytochemical bioassay of corticotrophin, in 1972. Since then, cytochemical bioassays have been described for several polypeptide hormones, and these assays are already widely used. It is expedient that the subject should be reviewed, as it is in this monograph, by one writer who has had the good fortune to have taken part in the growth of cytochemistry from its early origins to its present position as the basis of possibly the most sensitive bioassay system currently available. However, it should be noted that major contributions have been made by many, both to the development of the subject and to the establishment of the bioassays. The object of this preface is to try to give some perspective to the growth of this subject and to record that the cytochemical bioassay system has been fostered by many outstanding scientists in an atmosphere of remarkable goodwill. To begin with, there could have been no cytochemical bioassays until cytochem istry had been converted from its rather unsure origins into a precise and quantitative form of cellular biochemistry. This was done with skill and enthusiastic dedication by my colleagues, Dr. Lucille Bitensky, Dr. F. P. Altman, Dr. R. G. L. W. Poulter and Mr. A. A. Silcox, first at the Royal College of Butcher, Dr.

Cytochemical Bioassays: Techniques and Clinical Applications describes the techniques and clinical applications of cytochemical bioassays, particularly with respect to polypeptide hormones. This book discusses the clinical and research implications of studies that use these techniques. This text is comprised of 14 chapters; the first of which introduces the reader to the origins and general principles of cytochemical bioassays, along with their advantages. This discussion is followed by a chapter that explains what is meant by ""an assay""; for what purpose assays are done; the basic components of an assay method; and the nature of the difference between in vivo and in vitro hormone bioassays, in vitro ligand assays, and enzyme assays. Attention then turns to the techniques of cytochemical bioassays and the cytochemical bioassay procedures for adrenocorticotropic hormones; thyroid-stimulating hormones; the thyroid-stimulating antibody of Graves' disease; thyroid growth stimulating and blocking immunoglobulins; and luteinizing hormones. The next chapters focus on the technique and clinical relevance of a cytochemical bioassay for gastrin-like activity and for measurement of antidiuretic hormones, parathyroid hormones, angiotensin II, natriuretic hormones, and hypothalamic regulating hormones. This book will be of interest to clinicians and practitioners of biology, biochemistry, and endocrinology.

If you want practical information on how to use this book please refer to "Note to the Readers" p. VII. Histochemistry and cytochemistry are essential tools in biomedical research and routine service laboratories. Most texts on histochemistry fall into one of two categories: 1. Encyclopaedic texts covering all or nearly all information available on the whole or selected parts of histochemistry. 2. Reviews or surveys of methods found to be useful by the author(s). While the former category often appeals to the more philosophically inclined reader, direct guidance on the selection of technique may be difficult to find. In contrast, the latter category are often excellent sources for details on how to perform a particular method with a reasonable chance of success. Consideration of the exact mechanism of staining, of possible reasons for failure, and of alternative techniques are, however, frequently lacking. This book is an introduction to the scientific basis of histochemistry and is intended to provide a background for the selection and development of appro priate methods. It is not a "cook book" and readers expecting exhaustive methodological descriptions will be disappointed. Although most ofthe contributors to this book would not describe themselves as histochemists, they have all at some time found it essential to develop a basic understanding of histochemistry. This book contains the information they would have greatly appreciated ready access to at that time.

First multi-year cumulation covers six years: 1965-70.

This text presents a range of topics from the molecular events surrounding hormone actions to epidemiologic studies of the effects of environmental and occupational chemicals on reproductive organs. The endocrine systems covered include the adrenal cortex, thyroid and parathyroid, gonads, and the endocrine pancreas. Of particular importance are the

The idea for this book developed as an outcome of a multidisciplinary sym posium entitled "Pituitary Adenoma Update" that was held at Tufts-New En gland Medical Center in April 1977. The purpose of that symposium was to put together our current knowledge of the cause of pituitary tumors and discuss the diagnostic evaluation and management that was now appropriate, in light of the rapid advances that had taken place so recently in this area. Those of our colleagues who had presented papers at the symposium, as well as a number of others, were invited to contribute to this volume, which should serve as a presentation of the "state of the art" on all aspects of pitu itary tumors. We felt that such a book would be of value to endocrinologists, neurosurgeons, neuroradiologists, and pathologists who are involved in the investigation or care of patients with pituitary disorders. For a number of reasons, a review of pituitary adenomas seems particu larly timely. Rapid advances have taken place coincidentally in the fields of neurosurgery, neuroendocrinology, neuroradiology, neuropathology, and neuropharmacology. Seven major developments in these areas have occurred independently and almost simultaneously that have virtually revolutionized our approach to pituitary adenomas.
