Natural selection operates among individual organisms which differ in their genetic constitution. The degree of hereditary variability within a species is greatly enhanced by cross-fertilization. Indeed, the mechanism of sexual reproduction occurred very early in evolution, for it is seen today even in bacteria. In Escherichia coli, fertilization occurs by passage of the single chromosome from the male into the female bacterium (LEDERBERG, 1959). In multicellular organisms, the separation of germ from soma, and the production of haploid gametes became mandatory. The gametes were of two types. One, extremely mobile, was designed to seek out and penetrate the other, which loaded with nutrients, received the mobile gamete and intiated the development of a new individual. The foundation for true bisexuality was thus laid. In the primitive state of bisexuality, whether an individual is to be a sperm-producing male or an egg-producing female appears to be decided rather haphazardly. In the worm, Banelia viridis, the minute males are parasites in the female. Larvae that become attached to the proboscis of an adult female become males, while unattached larvae sink to the bottom and become females (BALTZER, 1935). The more sophisticated state of bisexuality was initiated by setting aside a particular pair of chromosomes for specialization and making either the male or the female a heterogametic sex. Sex chromosomes as we know them were thus born.
Immunopathology of Insulin: Clinical and Experimental Studies

Soon after the discovery of insulin in 1922, it became clear that the use of this hormone in the treatment of diabetics is often accom panied by allergy. In 1956 it became possible to determine quantita tively the insulin-binding antibodies which are responsible for the resistance to insulin. The methods developed since then make it possible to measure minute amounts of the pancreatic hormone in blood and extracellular fluids. There have been many attempts to relate insulin allergy and in sulin resistance to the primary, secondary or tertiary structure of the or B chains, or both, and more recently, to the proinsulin which is A present in all commercial preparations of insulin, i. e. to the species specific structure of the C peptide. In the great majority of papers dealing either with the immunogenic and antigenic properties of in sulin or with the relevant antibodies, the discussion has been restricted to the humoral antibodies. The existence of a brief period of delayed local allergy resulting from the cellular immune response has more or less escaped attention. It is specifically this period of delayed allergy that attracted the interest of Dr. FEDERLIN and his colleagues. Making use of immuno histological and other techniques which are rarely employed in clinical observation, and with the help of experiments on animals, Dr. FEDERLIN traces the course of insulin allergy from cellular immunity, through the production of humoral antibodies by the insulin-binding cells of the circulation, to the sessile immunological apparatus.
Tracer Methods in Hormone Research

The purpose of this monograph is to describe theoretical aspects of the interpretation of data obtained from experiments performed with labeled hormones. Quantitative endocrinologic studies involving the use of tracers include the determination of rates at which hormones are secreted by endocrine glands and are produced outside these glands by conversion of other secreted hor mones. Tracer experiments are also performed with the purpose of measuring rates of metabolic reactions. These measurements reveal the contribution of secreted hormones to the formation of circulating compounds and urinary metabolites. The estimation of rates of fetal and placental production and exchange of hormones characterizes a class of in vivo quantitative studies performed with isotopically labeled hormones (radioactive or not). In addi tion, tracers are used to measure permeability and rates of reaction in in vitro systems, and to study the uptake of hormones by tissues, both in vivo and in vitro. The stability of the steroid nucleus carrying the isotopic label and the large number of reversible metabolic reactions in which steroids are involved, both facilitated and motivated the development of a sophisticated theoretical treat ment of tracer experiments in the field of endocrinology. Although the prac tical examples used to illustrate the concepts and calculations presented in this monograph involve labeled hormones, the theory is presented in a general symbolic manner and is applicable to other fields of investigation.
Female Sex Steroids: Receptors and Function

It is the object of this series of monographs to present the experiments and interpre tations of a given laboratory. We have attempted in this volume to present our view of receptor-steroid interactions and their relation to steroid-induced responses. This view is necessarily biased by our own experimental results. While we have tried to in clude the views and results of others, this volume is not meant to be comprehensive. Rather it is selective and examines those topics within the general field of steroid hor mone action which we have addressed at the laboratory bench. The work reviewed in this volume would not exist without the help and support of many associates. Our mentors included Jorge Awapara, Jack Gorski, Henry Komer, Bill Ray, and Mike Zarrow. Associates instrumental in this work include George Barr, John Burgner, Sam Campbell, Constance Cardasis, Hitkan Eriksson, Stan Glasser, Jim Hardin, Mohammed Kalimi, Bruce Lester, Barry Markavarich, Shirley McCormick, Tony Means, Dan Medina, Ann Miller, Bert O'Malley, Helen Padyku la, Zigmund Paszko, Dale Snow, Susan Upchurch and Marian Walters. Students who have contributed to this effort include John Anderson, Joe DeLibero, Aaron Hsueh, Katrina Kelner, Debbie Metzger, Randy Richards, Jim Schaeffer, Mike Tytell, Lane von Brunt, and Cheryl Watson. Technicians without whose assistance this work could not exist include Toni Cetti, Wendy D'Attilio, Jeanie Haselby, Lily Hsueh, Helen Hyland, Jim Kovar, Kathy O'Connor, and Peggy Sansone."
Hormonal Control of Lactation

Research on the hormonal control oflactation - the subject of this monograph - has long been the major interest of this laboratory. Studies were initiated in the mid 1930s by the late Professor S. 1. Folley, FRS, who directed the work with immense enthusiasm and devotion until his untimely death in 1970. This fruitful area of basic and applied research has, in recent years, attracted widespread attention; there have been many exciting events and developments with a dramatic increase in the number of publications. These events are diverse and include the identification, isolation and sequencing of human prolactin; the identification and isolation of placentallactogens in several ruminant species with recognition of their importance in mammary growth and differentiation; the introduction of highly sensitive bioassay, radioimmuno- and radioreceptor-assay techniques for mammotrophic hormones; the growing clinical appreciation of the immunological and nutritional importance of colostrum and milk to the newborn; the intensification of studies on normal mammogenesis to establish a sound basis for studies on mammary cancer; and the exploitation of the mammary gland, with its characteristic differentiation patterns and multiple synthetic abilities, as a valuable tissue for the investigation of basic mechanisms involved in the synthesis under hormonal control of enzymes and secretory proteins; and for the study of hormone - receptor interactions.
Hirsutism

In the past 10 years hirsutism has been the object of a considerable number of fundamental studies. It provides endocrinologists with an experimental model for the investigation of androgen secretion, metabolism and mechanism of action. Plasma androgen assay, free testosterone measurement, hepatic and extrahepatic androgen metabolic clearance and androgen metabolism in the skin are the different steps which were studied by many groups and represent valuable parameters of the mechanisms of hirsutism. Determination of the origin of androgen oversecretion has become easier by technical progress in differential effiuent venous catheterism, which makes it possible to compare androgens in adrenal or ovarian effiuent veins to their peripheral levels, and to determine the ovarian or adrenal source of the androgen oversecretion as well as the side responsible, essential in the case of tumors. The study of androgen metabolism and the discovery of androgen receptors in the skin confIrm the latter as an actual target cell for androgens. This target cell uses the circulating active androgen, i. e. , testosterone and can also metabolize local inactive androgens into active ones. This is the case of androstenedione and dehy droepiandrosterone which are the two main androgens secreted in women, since women secrete very little testosterone. The capacity of the skin to transform inactive androgens into active ones varies from one individual to another. That would support the concept of variable skin receptivity from one woman to another and from one ethnic group to another.
Auto-immunity in the Endocrine System

The present monograph will concern itself with those disorders of the endocrine system, either associated with destruction, interference with function or hyper function, which are considered to be due to auto-immune processes. Endocrinopathies Non-endocrine auto-immune disorders associated with the endocrinopathies Graves' (Basedow's, Parry's) disease Pernicious anaemia Hashimoto's thyroiditis Vitiligo Idiopathic Addison's disease Myaesthenia gravis Insulinopenic diabetes mellitus Sjogren's syndrome Auto-immune oophoritis and orchitis Rheumatoid arthritis Auto-immune hypoparathyroidism Idiopathic thrombocytopenic purpura Auto-immune hypophysitis Chronic active hepatitis Possibly some cases of infertility Primary biliary cirrhosis due to anti-sperm antibodies Reproduced with permission from Volpe (1977) The above table indicates those organ-specific endocrinopathies considered to be due to auto-immune factors, as well as those non-endocrine, organ-specific auto-immune disorders which may be associated with them (Volpe 1977). It is evident that such disorders, occurring without any obvious external cause, raise the very elementary question of how immune processes directed against self constituents could be initiated. Generally, of course, the immune system acts as a regulatory and defence mechanism, and disorders of auto-immunity represent breakdowns in this regulatory system. The following chapters will be concerned with the individual components ofthe endocrine system so affected by auto-immune processes; it will first be necessary to provide an initial chapter for the purpose of summarizing some general principles of immunology, in order to place the immune disorders of the endocrine system in context.
Hormones in Human Amniotic Fluid

This monograph represents the first comprehensive review of hormones in human amniotic fluid and includes data published up to and including 1980. Recently, more extensive use of amniocentesis for prenatal diagnosis and evaluation of fetal lung maturation has shown that amniotic fluid hormone measurements can aid in the diagnosis of fetal and placental abnormalities. The material is presented in two main sections dealing with steroid and protein hormones. The methods of identification and quantitation are delineated, and the findings are discussed in relation to the clinical conditions. In addition, particular attention has been directed towards up-to-date review of the sources, metabolism and transfer of human amniotic fluid hormones. The review is intended to serve the needs of clinicians, basic scientists and students, providing detailed information on human amniotic fluid hormones in order to improve patient care and indicate possibilities for further investigations.

Cushing’s Syndrome

The unraveling of our knowledge of the functions of the adrenal gland constitutes one exciting development of modern medicine and biochemistry. We owe these advances to the felicitous cooperative efforts of the clinical investigator and the biochemist. Three centuries elapsed between the first recorded anatomical descrip tion of the adrenals and the demonstration by Dr. Addison in the mid-nineteenth century of the fatal results of the destruction of these glands by disease. It became evident from this observation that the adrenals secreted a "factor" or "factors" essential to life. It took approximately 90 years to isolate this elusive vital factor - cortisone - from beef adrenal cortices, independently by both Reichstein and his co-workers in Basle and Kendall and his group in the United States and another 10-15 years before it became more generally available for experimental and clinical use. It is perhaps difficult to believe that as recently as 35-40 years ago, before cortisone and cortisol were clinically available, the surgical removal of a benign adrenal cortical tumor in patients with Cushing's syndrome was associated with a prohibitive postoperative mortality rate. Within 12-36 h after operation, most of such patients developed an intractable state of shock, which was not manifested by significant electrolyte abnormalities or hypoglycemia and was unresponsive to the usual treatment for shock plus the generous use of salt-retaining hormone.
Prolactin: Physiology, Pharmacology and Clinical Findings

Lactogenic hormone activity was first observed in bovine pituitary extracts by Stricker and Griiter in 1928, working in Bouin's laboratory in Strasbourg. Since that time prolactin has been shown to exist in anterior pituitary extracts of almost all vertebrate species investigated. Although its biology was extensively studied in many mammalian species, the existence of prolactin in the human was generally doubted, despite the positive evidence produced by such researchers as Pasteels. This can partly be explained by the fact that human growth hormone isolated in 1961, is itself a potent lactogen, in contrast to nonprimate growth hormones, and is present in the normal human pituitary in much greater amounts than prolactin. As a result there was a lag of nearly 10 years until prolactin was unanimously accepted as a hormone of the human pituitary, separate from human growth hormone. In 1970 new bioassay techniques permitted the demonstration of prolactin bioactivity in the serum of postpartum women and galactorrhea patients, and chromatographic methods led to the isolation and purification of human prolactin allowing the establishment of a specific radioimmunoassay for this hormone. This opened the road to the understanding of prolactin physiology and pathophysiology in the human, which has revolutionized clinical neuroendocrinology and reproductive endocrinology. Particularly hyperprolactinemia has turned out to be one of the most common endocrine syndromes.
The Pituitary and Testis: Clinical and Experimental Studies

This monograph brings together our work concerning the relationships be tween the hypothalamus, pituitary and testis. The studies span approximate ly a decade of collaborative work. Over this period our contributions and those of many others have advanced greatly our understanding of many aspects of male reproductive biology. This monograph attempts to survey these developments and to highlight many unresolved issues. It also provides an opportunity to demonstrate the value of investigations which relate bio chemical to structural parameters and to illustrate the importance of animal studies in elucidating biological principles with clinical applications. The reverse is also important since the pathophysiology of human disorders of ten provides insight into hitherto unsuspected basic mechanisms. In any rapidly expanding field it is difficult to stop revising and extending a manuscript. It is equally difficult to quote every reference in the field but we trust that those of significance have not been omitted. Some of our former students have collaborated with us as co-authors in producing this monograph. It is equally important to recognise the contributions of our other former students and colleagues who have physically participated in the studies and without whose intellectual contributions a number of concepts would not have been elucidated. Their work is acknowledged in the text of the monograph and the extensive list of references.
