This monograph on the "Ultrastructure of Human Sella Tumors" is in fact a study of the correlations of clinical findings and morphology. It is a timely and eagerly awaited publication because of the increasing interest of the endocrinologist in pituitary disorders and of the neuro surgeon in the newest aspects of surgery on pituitary tumors, and also because of the unsatisfactory but still widely accepted classification into eosinophil, basophil and chromophobe pituitary adenomas. This old classification has been mainly based on granule color as seen after hematoxylin-eosin staining, but it does not, after extensive clinical observations, reflect in many instances the type of clinical picture observed. The author has brilliantly succeeded in demonstrating in a convinc ing way, by an extensive study of the relevant literature and by his own histological work, that further insight into the biology of the hypophysis and of the pituitary tumor can be obtained only by newer methods of light microscopic staining, immuno-histochemistry and electron microscopy combined with radio-immunological blood hormone determination.

Despite recent technological innovations in neuroradiology, the ultimate diagnosis of brain tumors is still based on the histopathological findings from specimens taken during surgery. The material in this atlas represents approximately 700 brain tumor specimens collected mainly in the authors' own clinics. In most cases, complementary light-and-electron-microscopic images of the same case are presented. This volume is a clear and comprehensive guide to the pathology of tumors arising from the central nervous system and should prove useful to pathology residents, neurologists, neurosurgeons, neuroradiologists, and senior medical students.

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.

Innovative microscopic techniques, introduced during the last two decades, have contributed much to creating a new picture of the dynamic architecture of the cell, which can now be more exactly correlated with specific biochemical and physiopathological events. These developments have led to significant advances in our understanding of the physiomorphological and pathological aspects of the secretory mechanism, as well as the pharmacologic methods used to control, experimentally, the function of exocrine and endocrine glands. The integration of new ultrastructural methods such as freeze-fracture/etching, immunocytochemistry, scanning and high-voltage electron microscopy, cytoautoradiography, etc. , has proven to be of great value when applied to the study of endocrine cells and tissues. Because information on this topic has appeared in a variety of scientific and medical journals, this book: (1) reviews the results of an integrative approach presenting a comprehensive ultrastructural account of the main aspects of the field; (2) points out gaps or controversial topics in our knowledge; and (3) outlines pertinent directions for future research. The chapters, prepared by recognized authorities in the field, present traditional information on the topic in a concise manner and, with a valuable selection of original illustrations, show what the integration of new microscopic methods can contribute to the subject in terms of new concepts. This volume will be useful to cell biologists, anatomists, embryologists, histologists, pharmacologists, pathologists, and, of course, endocrinologists. It will also be of interest to students, practitioners of medicine, and to all others dealing with clinical research and diagnosis.

Prolactin Secretion: A Multidisciplinary Approach covers the proceedings of the 1982 symposium on the frontiers and perspective of prolactin secretion through a multidisciplinary approach, convened in Nabor Carrillo Hall of the Natural University of Mexico. The symposium represents a genuine interdisciplinary effort to provide insights into the complexities of prolactin. Separating 24 manuscripts into chapters, this book first discusses studies on the molecular evolution of prolactin (PRL) and the related growth hormones and placental lactogens and the relevance of these studies for biological research on PRL, with particular emphasis on PRL secretion. Significant topics on the physiology, biochemistry, synthesis regulation, structure, function, glycoconjugates, gene expression control, regulatory, and control mechanisms of PRL and its secretion are considered in the subsequent chapters. This book also examines the action(s) of dopamine on the PRL-producing cells, the effects of his-pro diketopiperazine on PRL secretion, and the role of cellular phospholipids and the Ca2+-calmodulin system as modulators of PRL release. The effect of the suckling stimulus on the induction of PRL release in different reproductive states and the role of PRL in parental behavior in selected species of mammals and birds are also considered. The concluding chapters describe the morphologic features of abnormal lactotrophs, the in vivo and in vitro secretory activity exhibited by different types of pituitary adenomas and hyperprolactinemia. This book serves as an important reference for a wide range of investigators and advanced medical students who are engaged in the study of basic and clinical prolactin physiology.

Since the time of the earliest electron microscopic studies on tumours of the human nervous system. undertaken over 20 years ago by Luse and her colleagues. there have been considerable advances in our understanding of these neoplasms. Tissue culture and specific antibodies to tumour antigens are two of the techniques which have greatly aided such advances. enabling much to be learned about the biological properties and underly ing nature of all types of nervous system tumour. Electron microscopy. however. has continued to prove of considerable value in the investigation of these tumours. and the technological advances of the last two decades have dramatically improved the resolution and overall quality of the ultrastructural images obtained. In clinical neuropathology. such improvements have encouraged a more widespread use of the electron microscope in the diagnosis of human nervous system tumours. alongside antibody techniques and more conventional histological methods. Although ultrastructural examination is often not strictly necessary to identify well-differentiated tumours such as astrocytomas or choroid plexus papillomas. study of the electron microscopic features in such cases fre quently proves useful in the diagnosis of their more malignant counterparts. Thus the recognition of astrocytic filaments in anaplastic gliomas. or of cilia in pleomorphic choroid plexus carcinomas. may enable a diagnosis to be made in cases where there is insufficient differentiation for the tumours to be recognised at light microscopic level.
