The Cytochemical Bioassay of Polypeptide Hormones


Book Description

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


Book Description

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.




Theory and Strategy in Histochemistry


Book Description

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.

The Pituitary Adenoma


Book Description

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.

New Actions of Parathyroid Hormone


Book Description

Shaul G. Massry Division of Nephrology, The University of Southern California, School of Medicine Los Angeles, California In the last two decades evidence has accumulated indicating that parathyroid hormone may exert a multitude of effects on many cells and a variety of organs beyond its classical targets: the kidney and the bone. These efforts have been spearheaded by nephrologists. The interest of this group of clinicians-scientists stems from the fact that patients with renal failure have secondary hyperparathyroidism and markedly elevated blood levels of PTH (1,2). If this hormone does act on various organs, it becomes plausible that excess blood levels of PTH may be harmful in these patients. Indeed, in an Editorial published in 1977, Massry suggested that the elevated blood levels of PTH in patients with renal failure may exert deleterious effects on many systems and as such may participate in the genesis of many of the manifestations of the uremic syndrome (3). Thus, the essence of the Massry hypothesis is the notion that PTH may act as a major uremic toxin. The search for uremic toxins did not yield successful results. In the last three decades many compounds have been implicated as uremic toxins. However, a cause and effect relationship between these compounds and the manifestations of the uremic syndrome has not been established in most cases.
